a For any relation to be a function, an independent variable x cannot produce different dependent varible y

From the table,

when x = 5, y = 2

Also, when x = 5, y = 5

and when x = 5, y = 7

We can see that x= 5 produces 3 different values of y ( that is 2, 5, and 7). This has disobeyed the rule of a function

Question 3 Olivia is making pancakes for breakfast. The recipe calls for 0.5 quart of milk and 2.5 cups of flour. She has quart of 3/8 quart of milk and 18/8 cups of flour. Olivia makes the recipe with the milk and flour she has. Explain her error. Hint: Convert all of them to either decimal or fraction so that you can compare the values. Challenge: How much more or less milk does Olivia need? How much more or less flour does Olivia need?

Answers

ANSWER and EXPLANATION

The recipe calls for 0.5 quart of milk and 2.5 cups of flour.

She has 3/8 quart of milk and 18/8 cups of flour.

To know the error she made, we have to find the ratio of milk to flour in the recipe and the ratio of milk to flour that she used and see if the ratios are the same.

RECIPE

Ratio of milk to flour is:

[tex]\begin{gathered} 0.5\text{ : 2.5} \\ \Rightarrow\text{ 1 : 5} \end{gathered}[/tex]

That is the ratio of milk to flour.

USED BY OLIVIA

Ratio of milk and flour that she used is:

[tex]\begin{gathered} \frac{3}{8}\text{ : }\frac{18}{8} \\ =>\text{ 3 : 18} \\ \Rightarrow\text{ 1 : 6} \end{gathered}[/tex]

We can already see that the ratios are not the same.

By comparing the ratios, we see that she actually used more flour than she was supposed to.

Find the area of the shaded sector of the circle. Leave your answers in terms of pi

Answers

Answer:

D. 8pi yd^2

Explanation:

Area of a sector is expressed as;

[tex]A\text{ = }\frac{\theta}{360}\times\pi r^2[/tex]

r is the radius of the circle

theta is the angle substended at the centre

Given the following

r = 9yd

theta = 360-200

theta = 160degrees

Substitute

A = 160/360 * pi(9)^2

A = 4/9*18pi

A = 72pi/9

A = 8pi yd2

Hence the area of the shaded sector is 8pi yd2

y=-x^2-4x-8Identify the vertex, the axis of symmetry, the maximum or minimum value, and the range of the parabola.

Answers

Here we have the following parabola:

[tex]y=-x^2-4x-8[/tex]

To find the vertex, we could use the following formula:

[tex]V(x,y)=V(\frac{-b}{2a},\frac{-b^2}{4a}+c)[/tex]

Where a, b and c are the coefficients of the quadratic function:

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

As you can see, in this problem a = -1 , b = -4 and c = -8. Thus,

[tex]V(x,y)=V(\frac{-(-4)}{2(-1)},\frac{-(-4)^2}{4(-1)}-8)[/tex]

This is:

[tex]V(-2,-4)[/tex]

Then, the vertex of the parabola is (-2,-4)

The axis of symmetry of the parabola is the line x=-2. Since the vertex is situated at the coordinates (-2,-4), that means that the parabola is symmetrical around this line.

The vertex is maximum point of the parabola.

The range, is defined as all the values that the y-axis could take. If we notice, that is:

A hose for the hot tub at a rate of 3.61 gallons per minute. How many hours will it take to fill a 345 gallon hot tub?

Answers

We have a 345 gallon hot tub that fills at a rate of 3.61 gallons/min.

To calculate filling time, we need to divide as it follows:

[tex]t=\frac{345\text{gal}}{3.61\frac{\text{gal}}{\min }}[/tex]

in that way we can find how much time does it take in minutes

[tex]t=\frac{345}{3.61}=95.56786[/tex]

now, if we want to determine time in hours, we must divide by 60, because there are 60 min. in one hour.

[tex]t=\frac{345}{3.61}\cdot\frac{1}{60}=1.59279[/tex]

Then, it would take approximately 1.59 hours to fill the hot tub.

Answer:

Given that,

To find,

[tex]R(x)=\frac{f(x)}{g(x)}[/tex]

where,

[tex]f(x)=\frac{x^2-x-30}{10x+100}[/tex][tex]g(x)=\frac{-x^2-5x+66}{11x+110}[/tex]

Simplifing f(x) and g(x), we get

[tex]f(x)=\frac{x^2-x-30}{10x+10)}=\frac{x^2-6x+5x-30}{10(x+10)}[/tex][tex]=\frac{x(x-6)+5(x-6)}{10(x+10)}=\frac{(x-6)(x+5)}{10(x+10)}[/tex][tex]f(x)=\frac{(x-6)(x+5)}{10(x+10)}-----(1)[/tex]

This is the simplified form of f(x).

For g(x) we get,

[tex]g(x)=\frac{-x^2-5x+66}{11x+110}=\frac{x^2+5x-66}{-11(x+10)}[/tex][tex]=\frac{x^2+11x-6x-66}{-11(x+10)}=\frac{x(x+11)-6(x+11)}{-11(x+10)}[/tex][tex]g(x)=\frac{(x+11)(x-6)}{-11(x+10)}------(2)[/tex]

[tex]\frac{i}{g(x)}=\frac{-11(x+10)}{(x+11)(x-6)}[/tex]

Now To find R(x), we get

[tex]R(x)=\frac{f(x)}{g(x)}=f(x)\times\frac{1}{g(x)}[/tex][tex]=\frac{(x-6)(x+5)}{10(x+10)}\times\frac{-11(x+10)}{(x+11)(x-6)}[/tex][tex]=\frac{-11(x+5)}{10(x+11)}[/tex]

we get,

how would I graph 3x + 4y = -4

Answers

Answer:

To graph a line you have to find two points on the line, one way of doing this is first setting x=0 and solving for y, as follows:

[tex]\begin{gathered} 3(0)+4y=-4, \\ 4y=-4, \\ y=-1. \end{gathered}[/tex]

With the above calculations, we got that the point (0,-1) is on the line.

Now, to find another point on the line we set y=0 and solve for x:

[tex]\begin{gathered} 3x+4(0)=-4, \\ 3x=-4, \\ x=-\frac{4}{3}\text{.} \end{gathered}[/tex]

With the above calculations, we got that the point (-4/3,0) is on the line.

Once we have those points we draw the line that passes through those points.

The graph of the given equation is:

Where x is the horizontal distance in feet from the point at which the ball is thrown.How far from the child does the ball strike the ground?

Answers

To calculate the maximum distance that the ball takes, we can use the first and second derivatives of y to find out this. We have:

[tex]\begin{gathered} y=-\frac{1}{14}x^2+4x+3 \\ \Rightarrow y^{\prime}=-\frac{2}{14}x+4=-\frac{1}{7}x+4 \\ \Rightarrow y^{\doubleprime}=-\frac{1}{7} \end{gathered}[/tex]

Using the second derivative criterion, we have that y'' < 0, therefore, we have a maximum in the root of the first derivative. For that, we get the following:

[tex]\begin{gathered} y^{\prime}=0 \\ \Rightarrow-\frac{1}{7}x+4=0 \\ \Rightarrow\frac{1}{7}x=4 \\ \Rightarrow x=7\cdot4=28 \\ x=28 \end{gathered}[/tex]

Therefore, at x=28 is where the maximum distance is. Now we only substitute x=28 in y to find out:

[tex]\begin{gathered} y=-\frac{1}{14}(28)^2+4(28)+3 \\ \Rightarrow y=-\frac{1}{14}(784)+112+3 \\ \Rightarrow y=-56+112+3=59 \\ y=59 \end{gathered}[/tex]

Finally, we have that the ball will go 59 feet from the child

Answer:

[tex]\textsf{13.\;a)}\quad d=\dfrac{P}{0.5 \pi +1}[/tex]

[tex]\textsf{13.\;b)}\quad d=14\; \sf inches[/tex]

Step-by-step explanation:

Question 13

The perimeter, P inches, of a semicircle of diameter, d inches, is represented by the equation:

[tex]\boxed{P=0.5 \pi d+d}[/tex]

Part (a)

To express d in terms of P, rearrange the equation to isolate d.

Factor out the common term d from the right side of the equation:

[tex]\implies P=d(0.5 \pi +1)[/tex]

Divide both sides by (0.5π + 1):

[tex]\implies \dfrac{P}{0.5 \pi +1}=\dfrac{d(0.5 \pi +1)}{0.5 \pi +1}[/tex]

[tex]\implies \dfrac{P}{0.5 \pi +1}=d[/tex]

[tex]\implies d=\dfrac{P}{0.5 \pi +1}[/tex]

Part (b)

Given:

Perimeter = 36 in[tex]\pi \approx \dfrac{22}{7}[/tex]

Substitute the given values into the equation derived in part (a) and solve for d:

[tex]\implies d=\dfrac{36}{0.5 \left(\frac{22}{7}\right) +1}[/tex]

[tex]\implies d=\dfrac{36}{\frac{11}{7} +1}[/tex]

[tex]\implies d=\dfrac{36}{\frac{11}{7} +\frac{7}{7}}[/tex]

[tex]\implies d=\dfrac{36}{\frac{18}{7}}[/tex]

[tex]\implies d=36 \times \dfrac{7}{18}[/tex]

[tex]\implies d=\dfrac{252}{18}[/tex]

[tex]\implies d=14[/tex]

Therefore, the diameter is 14 inches.
