write the following degrees in radian measure (a) 80 degrees(b) 120 degrees (c) 90 degrees (d) 270 degrees(e) 135 degrees

Answers

Answer 1

Answer

(a) 80 degrees = (4π/9) radians = 0.444π radians = 1.397 radians.

(b) 120 degrees = (2π/3) radians = 0.667π radians = 2.095 radians.

(c) 90 degrees = (π/2) radians = 0.50π radians = 1.571 radians.

(d) 270 degrees = (3π/2) radians = 1.50π radians = 4.714 radians.

(e) 135 degrees​ = (3π/4) radians = 0.75π radians = 2.357 radians.

Explanation

To do degree to radians conversion, we need to first note that

360° = 2π radians

So, for each of these cases, if we let the value of the angle given in degree be x in radians, then we can easily solve for x for each ot them

(a) 80 degrees

80° = x radians

360° = 2π radians

We can write a mathematical relationship by cross multiplying

(360) (x) = (80) (2π)

360x = 160π

Divide both sides by 360

(360x/360) = (160π/360)

x = (4π/9) = 0.444π

80° = (4π/9) radians = 0.444π radians = 1.397 radians

(b) 120 degrees

120° = x radians

360° = 2π radians

We can write a mathematical relationship by cross multiplying

(360) (x) = (120) (2π)

360x = 240π

Divide both sides by 360

(360x/360) = (240π/360)

x = (2π/3) = 0.667π

120° = (2π/3) radians = 0.667π radians = 2.095 radians

(c) 90 degrees

90° = x radians

360° = 2π radians

We can write a mathematical relationship by cross multiplying

(360) (x) = (90) (2π)

360x = 180π

Divide both sides by 360

(360x/360) = (180π/360)

x = (π/2) = 0.50π

90° = (π/2) radians = 0.50π radians = 1.571 radians

(d) 270 degrees

270° = x radians

360° = 2π radians

We can write a mathematical relationship by cross multiplying

(360) (x) = (270) (2π)

360x = 540π

Divide both sides by 360

(360x/360) = (540π/360)

x = (3π/2) = 1.50π

270° = (3π/2) radians = 1.50π radians = 4.714 radians

(e) 135 degrees​

135° = x radians

360° = 2π radians

We can write a mathematical relationship by cross multiplying

(360) (x) = (135) (2π)

360x = 540π

Divide both sides by 360

(360x/360) = (270π/360)

x = (3π/4) = 0.75π

135° = (3π/4) radians = 0.75π radians = 2.357 radians

Step-by-step explanation:

as this is a right-angled triangle, we use Pythagoras to get also c :

c² = a² + b² = 2² + 7² = 4 + 49 = 53

c = sqrt(53)

we know, sine = opposite/Hypotenuse.

so,

sin(A) = 2/sqrt(53) = 0.274721128...

from the norm circle we know cosine is the other leg of the right-angled triangle :

cos(A) = 7/sqrt(53) = 0.961523948...

tan(A) = sin(A)/cos(A) = 2/7 = 0.285714286...

sec(A) = 1/cos(A) = sqrt(53)/7 = 1.040015698...

csc(A) = 1/sin(A) = sqrt(53)/2 = 3.640054945...

cot(A) = 1/tan(A) = cos(A)/sin(A) = 7/2 = 3.50

Be sure to fully show the system of equations for each problem and the process used to solve the system.You are starting an office-cleaning service. You decide to charge both large and small offices. You charge $55 for a small office and $85 for a large office. You clean 14 offices and make $920. How many small offices and how many large offices did you clean?

Answers

Given:

The charge for a small office = $55.

The charge for a large office = $ 85.

The total number of offices = 14.

The total amount = $ 920.

Required:

We need to find a number of small offices and large offices.

Explanation:

Let x be the number of the small office and y be the number of the large office.

The equation of the total number of offices.

[tex]x+y=14[/tex]

[tex]x=14-y[/tex]

The equation of the total amount.

[tex]55x+85y=920[/tex]

Substitute x =14-y in the equation.

[tex]55(14-y)+85y=920[/tex]

[tex]55\times14-55y+85y=920[/tex]

[tex]770+30y=920[/tex]

Subtract 770 from both sides of the equation.

[tex]770+30y-770=920-770[/tex][tex]30y=150[/tex]

Divide both sides by 30.

[tex]\frac{30y}{30}=\frac{150}{30}[/tex][tex]y=5[/tex][tex]Substitute\text{ y=5 in the equation x=14-y.}[/tex][tex]x=14-5[/tex][tex]x=9[/tex]

Final answer:

The equations are

[tex]x+y=14[/tex]

[tex]55x+85y=920[/tex]

The number of small offices are 9.

The number of large offices are 5.

Choose the correct way to end the sentence.The lines x – 2y = 4 and y = 2x – 2 areA. parallelB. neitherC. perpendicular

Answers

Given the equations of the lines:

[tex]\begin{gathered} x-2y=4\rightarrow(1) \\ y=2x-2\rightarrow(2) \end{gathered}[/tex]

We will write both equations in slope-intercept form to find the slope of each line:

The equation of the first line:

[tex]\begin{gathered} x-2y=4 \\ -2y=-x+4\rightarrow(\div-2) \\ \\ y=\frac{1}{2}x-2 \end{gathered}[/tex]

so, the slope of the line (1) = 1/2

the equation of the second line:

[tex]y=2x-2[/tex]

so, the slope of the second line = 2

Comparing the slopes of the lines:

1) the slopes are not equal, so the lines are not parallel

2) the product of the slopes = 1/2 * 2 = 1

So, the lines are not perpendicular

so, the answer will be option B. neither

Patrick has a swimming pool that needs to be drained. His pool holds9,644.6 gallons of water and will need to drain completely in 8 hours.What is the change in the water level per hour for Patrick's swimmingpool? Round your answer to the nearest hundredth.

Answers

Explanation

We are asked to find the change in the water level per hour for Patrick's swimming

We have to use the formula

[tex]change\text{ in water level per hour=}\frac{Volume\text{ of water}}{Time\text{ taken to drain}}[/tex]

Thus

[tex]change\text{ in water level per hour=}\frac{9644.6}{8}=1205.575\text{ gallons per hour}[/tex]

Note: The rate will be negative because we are draining

Therefore, the change in water level will be -1205.58 gallons per hour

QuestionsWhat is the equation of the line?y = 2x - 4y = 1/2x + 2y = 2x + 2y = 1/2x-4

Answers

We have the graph of the equation, and we want to know the equation of the line.

We remember that we need to parts: the slope and the y-intercept. On the graph, we see that when x=0, the graph passes through the point 2, and thus the y-intercept is 2.

[tex]b=2[/tex]

Lastly, we will find the slope. For doing so, we will find two values of the line. In this case, we saw that the y-intercept is 2, so a point is (0,2).

Other point is (-4,0), as the x-intercept is -4.

For finding the slope, we remember the formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}=\frac{2-0}{0-(-4)}=\frac{2}{4}=\frac{1}{2}[/tex]

And thus, the slope is 1/2.

This means that the line equation will be:

where (x1,y1) and (x2,y2) are points through the graph.

Function 1.

From the table we have that the functions passes through the points (-11,8) and (-7,13), pluggin the values in the formula above we have:

[tex]\begin{gathered} m=\frac{13-8}{-7-(-11)} \\ m=\frac{5}{11-7} \\ m=\frac{5}{4} \end{gathered}[/tex]

Therefore the rate of change of functions 1 is 5/4

Function 2.

From the graph we notice that the functions passes through the points (-3,-4) and (1,-1), hence:

[tex]\begin{gathered} m=\frac{-1-(-4)}{1-(-3)} \\ m=\frac{-1+4}{1+3} \\ m=\frac{3}{4} \end{gathered}[/tex]

Therefore the rate of change of function 2 is 3/4.

Comparing both rates of change we conclude that Function 1 has the greater change of rate.

Answers

Answer:

Form:

[tex]\boxed{(x-9)^2=11}[/tex]

Solution:

[tex]x=12.32,5.68[/tex]

Explanation:

Step 1. The expression we have is:

[tex]x^2-18x+70=0[/tex]

And we are required to find the appropriate form after completing the square, and then the solution or solutions to the equation.

Step 2. Compare the given equation with the general quadratic equation:

[tex]ax^2+bx+c=0[/tex]

Our values for a, b, and c are:

[tex]\begin{gathered} a=1 \\ b=-18 \\ c=70 \end{gathered}[/tex]

Step 3. Using the value of b, find the following expression:

[tex](\frac{b}{2})^2[/tex]

The result is:

[tex](-\frac{18}{2})^2\longrightarrow(-9)^2[/tex]

Step 4. Take the original equation

[tex]x^2-18x+70=0[/tex]

Move the +70 as a -70 to the right-hand side:

[tex]x^2-18x=-70[/tex]

And now add to both sides the expression found in step 3 for (b/2)^2:

[tex]x^2-18x+(-9)^2=-70+(-9)^2[/tex]

Step 5. Factor the left-hand side of the equation as a perfect square binominal:

[tex]\begin{gathered} P\operatorname{erf}ect\text{ square binomial formula:} \\ (a\pm b)^2=a^2\pm2ab+b^2 \end{gathered}[/tex]

Applying this to our expression:

[tex](x-9)^2=-70+(-9)^2[/tex]

Step 6. Solve the operations on the right-hand side:

[tex]\begin{gathered} (x-9)^2=-70+81 \\ \downarrow\downarrow \\ \boxed{\mleft(x-9\mright)^2=11} \end{gathered}[/tex]

The form is the equation is:

[tex]\boxed{(x-9)^2=11}[/tex]

Step 7. To find the value or values of x, solve for x in the previous equation:

[tex]\begin{gathered} (x-9)^2=11 \\ \downarrow\downarrow \\ x-9^{}=\pm\sqrt[]{11} \\ \downarrow\downarrow \\ x^{}=\pm\sqrt[]{11}+9 \end{gathered}[/tex]

Step 8. To find the two solutions we use the '+' and '-' signs separately:

[tex]\begin{gathered} x^{}=\sqrt[]{11}+9\longrightarrow x=3.3166+9=12.3166 \\ x^{}=-\sqrt[]{11}+9\longrightarrow x=-3.3166+9=5.6834 \end{gathered}[/tex]

Rounding these values for x to the nearest hundredth (2 decimal places):

[tex]\begin{gathered} x=12.32 \\ x=5.68 \end{gathered}[/tex]

A root of the polynomial P(x) is the value of x for which the polynomial P(x) is equal to zero.

That is, any value of x that makes P(x) = 0, is a root of P(x).

The Multiplicity of a Root: This is the number of times a particular root appears as a root in a polynomial.

To find the root of a polynomial, say P(x), you have to equate P(x) to zero, and then solve for the value of x.

So, we shall follow the above procedures to find the root(s) of P(x), and thereafter determine if there are multiple roots.

[tex]\begin{gathered} P(x)=2x^4-4x^3-16x^2=0 \\ \text{Factoring out 2x}^2,\text{ we have} \\ 2x^2(x^2-2x-8)=0 \end{gathered}[/tex]

This means that:

[tex]\begin{gathered} x^2-2x-8=0 \\ or \\ 2x^2=0 \end{gathered}[/tex]

Solving quadratic equations above by Tthe Factorization Method, we get

[tex]\begin{gathered} x^2-2x-8=0 \\ x^2-4x+2x-8=0 \\ x(x-4)+2(x-4)=0 \\ (x-4)(x+2)=0 \end{gathered}[/tex]

So,

[tex]\begin{gathered} P(x)=2x^2(x-4)(x+2)=0 \\ \text{This means} \\ 2x^2=0\text{ }\Rightarrow x=0 \\ x-4=0\text{ }\Rightarrow x=4 \\ x+2=0\text{ }\Rightarrow x=-2 \\ So,\text{ the roots of P(x) are 0, -2, and 4} \end{gathered}[/tex]

Looking at the roots of P(x) above, there is no root that appears more than once, hence, the multiplicity of each of the roots is one.

How many kg of water are in a 132 kg person ?

Answers

Answer:

[tex]88kg\text{ of water}[/tex]

Explanation:

Here, we want to get the number of kg of water in a 132 kg person

From the question, there is a direct variation between kg of water in the human body and the mass of the body

Let the mass be m and the amount of water be w

By direct variation, with k as the proportionality constant, we have it that:

[tex]w\text{ = }km[/tex]

From the question, a 72 kg mass boy has 48 kg of water

Mathematically, we have it that:

[tex]\begin{gathered} 48\text{ = k }\times72 \\ k\text{ = }\frac{48}{72} \\ \end{gathered}[/tex]

Now, we want to get the kg of water in a 132 kg person

What we have to do here is to have k as 48/72 and solve for w

Mathematically, we have that as:

[tex]\begin{gathered} w\text{ = }\frac{48}{72}\times132 \\ \\ w\text{ = 88 }kg \end{gathered}[/tex]
