6. Let the measurement of ZBAC be 86° & ZBAD be 52°. What is the measurement of ZDAC? 1380 24° 52° 340
they asking me to find the answer by using compatible numbers 9÷ 5,138 9 and ? are compatible. the estimate is?
SOLUTION
Now, 9 and 51 are not compatible because 51 cannot divide 9 without a remaider.
The compatible number with 9 that is close to 51 is 54.
Hence,
9 and 54 are compatible.
This will give us
[tex]\frac{5400}{9}=600[/tex]Hence,
The estimate is 600
Hi tutor,What is the connection between the slope of a tangent of a function at a given point, and it’s derivative evaluated at that point? If possible, can you please use a diagram and derivation steps to help explain?
Given:
Derivative and sope of tangent
Required:
We want to define relation
Explanation:
The derivative of a function gives us the slope of the line tangent to the function at any point on the graph. This can be used to find the equation of that tangent line for example
and the slope of that tangent is the derivative of function at point P
Now to find equation of a tangent line
1) Find the first derivative of f(x).
2) Plug x value of the indicated point into f '(x) to find the slope at x.
3) Plug x value into f(x) to find the y coordinate of the tangent point.
4) Combine the slope from step 2 and point from step 3 using the point-slope formula to find the equation for the tangent line.

At first, we will find the volume of the cone and the volume of the sphere, then subtract them to find the answer
The rule of the volume of the cone is
[tex]V_c=\frac{1}{3}\times\pi\times r^2\times h[/tex]Since the height of the cone is 1 cm and its radius is 3 cm, then
h = 1 and r = 3
Substitute them in the rule above
[tex]\begin{gathered} V_c=\frac{1}{3}\times\pi\times(3)^2\times(1) \\ V_c=\frac{1}{3}\times\pi\times9\times1 \\ V_c=3\pi \end{gathered}[/tex]The formula of the volume of the sphere is

Two of the angles in a triangle measure 56° and 6° what is the measure of the third angle
The sum of angle in a triangle is 180°
If two of the angles in a triangle is 56° and 6°
Let x be the third angle
56 + 6 + x = 180° (sum of angle in a triangle)
62° + x = 180°
subtract 62° from both-side of the equation
x = 180° - 62°
x = 118°
Hence, the third side is 118°
Use the following figure and information to complete the proof. Given: m∥n Line l is a transversal of lines m and n. Prove: ∠3≅∠5
Answer:
1. Given.
2. Definition of vertical angles.
3. Vertical angles theorem.
4. Definition of corresponding angles.
5. Corresponding angles postulate.
6. Transitive property of congruence.
Explanation:
1. This statement is the given part of the problem
2. vertical angles are the pair of opposite angles that are formed when two line segments intersect. Angles 1 and 3 verify this definition, thus they're vertical angles.
3. The vertical angles theorem states that a pair of two vertical angles have the same measure.
4. Corresponding angles are the angles that are formed in matching corners with the transversal when two parallel lines are intersected by another line. Thus, angles 1 and 5 are corresponding angles.
5. The corresponding angles postulate states that, when two parallel lines are cut by a transversal, the resulting corresponding angles are congruent. Thus, angles 1 and 5 are congruent.
6. The transitive property of congruence states that if a is congruent to b and b is congruent to c, then a is congruent to c.
This means:
[tex]\angle3\cong\angle1\cong\angle5\Rightarrow\angle3\cong\angle5[/tex]
A swimming pool is in the form of a semicircular
The walk surrounding the pool has an area of 336.66 [tex]ft^{2}[/tex] .
A = ( Area of semicircle including side walk ) - ( Area of semicircle without side walk )
radius of smaller semicircle = 10 ft and radius of larger semicircle = 10 + 3 = 13 ft
A = [ ( 3.14 * [tex]13^{2}[/tex] ) / 2 ] - [ ( 3.14 * [tex]10^{2}[/tex] ) / 2 ]
= ( 530.66 - 314 ) / 2
= 108.33 [tex]ft^{2}[/tex]
Since we take walk on both sides , we will multiply it with 2
A = 2 * 108.33
A = 216.66[tex]ft^{2}[/tex]
One side of bigger rectangle = 20 + 3 + 3 = 26 ft
A = area of rectangle - area of square
A = ( 26 * 20 ) - [tex]20^{2}[/tex]
A = 120 [tex]ft^{2}[/tex]
Therefore ,
A = 216.66 + 120
A = 336.66 [tex]ft^{2}[/tex]
Hence , the walk surrounding the pool has an area of 336.66 [tex]ft^{2}[/tex] .

2. Kylie wants to earn $100 a month. She rakes leaves for $7 an hour and cleans windows for $6 an hour. Kylie cannot work more than 30 hours a week. Write the system of inequalities that represents this situation. Be sure to define your variables.
Let L be the amount of hours that Kylie works on raking leaves and W the amount of hours that she works on cleaning windows (on a week).
Since she cannot work more than 30 hours a week, and the total time spent working is L+W, then:
[tex]L+W<30[/tex]Since one month has 4 weeks, she should win $25 a week to earn $100 in a month. Since she gets paid $7 per hour for raking leaves, after L hours she would have won a total amount of 7L, and since she gets paid $6 for cleaning windows, she would have won 6W after W hours. The total amount of money earned would be 7L+6W, which should be greater than 25:
[tex]25\le7L+6W[/tex]Therefore, the system of inequalities that represents the situation, is:
[tex]\begin{gathered} L+W\le30 \\ 25\le7L+6W \end{gathered}[/tex]What is the answer to 720x+(-20x)

720x + (-20x) = 720x - 20x
Subtract 20 from 720
720 - 20 = 700, so
720x + (-20x) = 720x - 20x = 700x

The meaning of QUADRATIC EQUATION is any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power.
Step 2
We are required to Identify the two tables which represent quadratic relationships.
In a quadratic equation, we have a polynomial in x with degree 2. Hence the result in y or P(x) do get repeated as a polynomial contains x² in it.
Looking at the tables we will observe that;

Solution:
Given:
[tex]\begin{gathered} Head,H=4 \\ Total=12 \\ P(H)=\frac{4}{12} \\ P(H)=\frac{1}{3} \end{gathered}[/tex]From the probability, it can be deduced that as the number of trials increases, the observed frequency will get closer to the expected frequency.
Therefore, if the number of trials increases significantly, then the observed frequency of landing heads up gets closer to the expected frequency based on the probability of the coin landing heads up.

8. Bobbie is self-employed and made a profit of $22, 150 last year. She mustpay $2572 in income tax. She also must pay social security tax of 13.3% ofher profit. What is Bobbie's total tax liability? Round to the nearestdollar,a $5912b. $4998c. $5518
income tax = $2572
social security tax = 13.3% of the profit
= 13.3% of $22,150
= 13.3/100 * 22,150 = $2,945.95
So, the total tax =
2572 + 2,945.95 = $5,517.95
Rounding to the nearest dollar
the total tax = $5,518
The answer is option C. $5,518
I would like to work through how to determine whether this is even, odd or netiher.
We are given a function and are asked to determine if it's even, odd or neither. Our approach is to employ the negative test and modify the function to ascertain its status. This will be depicted below.
[tex]h(x)=-6x^3+x^2+8x+8[/tex]This is our original function, next, we find h(-x)
[tex]\begin{gathered} h(x)=-6x^3+x^2+8x+8 \\ h(-x)=-6(-_{}x)^3+(-x)^2+8(-x)+8 \\ h(-x)=6x^3+x^2-8x+8 \\ h(-x)=6x^3+x^2-8x+8 \\ h(-x)=-(-6x^3-x^2+8x-8) \end{gathered}[/tex]Looking at the function h(x) and h(-x), we have to put the polynomial in the correct degree. The input of the negative sign before the h(-x) function is to check if the function will maintain the same format with the original function, h(x). The disparity is what tells us if it is even, odd or neither of the two.
Now we know h(-x), we now use a certain set of conditions to test if function is even, odd or neither.
[tex]\begin{gathered} \text{if h(x)=h(-x), then function is even} \\ \text{if h(-x)=-h(x), then function is odd} \\ \text{if it is neither of the above, function is neither even nor odd.} \end{gathered}[/tex]In this case, based on the above criteria, the function is neither even nor odd.

Notice that the factor x is a common factor for all three terms. Then, factor out x:
[tex]x^3-2x^2-35x=x(x^2-2x-35)[/tex]Notice that the factor x²-2x-35 is a quadratic expression.
Find two numbers whose sum is -2 and whose product is -35 to factor out the quadratic expression. Since 5-7 = -2 and (5)(-7)=-35, those two numbers are -7 and 5. Then, the quadratic expression can be factored out as:
[tex]x^2-2x-35=(x-7)(x+5)[/tex]Then:
[tex]x(x^2-2x-35)=x(x-7)(x+5)[/tex]Then, the factorization of the given trinomial is:
[tex]x^3-2x^2-35x=x(x-7)(x+5)[/tex]Therefore, the correct choice is option C) x(x-7)(x+5)
