What is the length of AB? Enter your answer In the box, round only your final answer to the nearest tenth.
Answers
Angle B = 79°
Side a = 12
AB = side b
Use the Law of Cosines to find the length of side b.
b^2 = a^2 + c^2 − 2ac cos(B)
b^2 = (122 + 182) − ( 2 x 12 x 18) cos(79°)
b^2 = (144 + 324) − 432 x 0.191
b^2 = 468 - 432 x 0.191
b^2 = 468 - 82.429
b^2 = 385.571
b = √385.571
b = 19.636
Rounded to the nearest tenth is 19.6 cm.

What are the zeros of the polynomial function?
f(x)=x^2−16x+48
Enter your answers in the boxes.
The zeros of f(x) are ( ) and ( ).
Answers
the zeros are 12 and 4
Final answer:
The zeros of the polynomial function f(x) are (12) and (4).
Explanation:
The zeros of the polynomial function f(x) = [tex]x^2[/tex] - 16x + 48 can be found by factoring the quadratic equation or using the quadratic formula. To factor, we look for two numbers that multiply to give the constant term (48) and add to give the coefficient of the middle term (-16). After finding such numbers, the polynomial can be factored into two binomials.
In this case, the two numbers are -12 and -4 because (-12) * (-4) = 48 and (-12) + (-4) = -16. Therefore, the factored form of the polynomial is (x - 12)(x - 4).
To find the zeros, we set each factor equal to zero:
x - 12 = 0 ⇒ x = 12
x - 4 = 0 ⇒ x = 4
Hence, the zeros of the polynomial function f(x) are (12) and (4).

One side of a right triangle is 2 cm shorter than the hypotenuse and 7 cm longer than the third side. find the lengths of the sides of the triangle.
Answers
If the hypotenuse - H
Then one side is - H - 2
Third side is 7 cm shorter then H-2
Therefore it’s H -2-7 = H -9
According to Pythagoras theorem
Square of hypotenuse = sum of the squares of the other 2 sides
H² = (H-9)² + (H-2)²
H² = H² -18H + 81 + H² -4H + 4
0 =H² -22H +85
This is a quadratic equation
0 = H² - 17H -5H +85
0 = H (H - 17) -5(H-17)
(H-17) (H-5) =0
H -17=0 or H-5=0
H could be 17 cm or 5 cm
If H =5 cm then
Side 1 -H-2 = 3 cm
And side 2 - H-9 = -4 cm
Since lengths cannot be negative values
H isn’t 5 cm
Therefore H =17 cm
1 side is H-2 = 15 cm
2nd side H -9 = 8 cm
Three sides are 17 cm, 15 cm and 8 cm
The sides will be 17, 15, and 8.
TriangleIt is a polygon of three sides and the sum of the internal angle of a triangle is 180 degrees.
Given
One side of a right triangle is 2 cm shorter than the hypotenuse
And 7 cm longer than the third side.
To findThe lengths of the sides of the triangle.
How do find the lengths of the sides of the triangle?Let the hypotenuse is H
Then the One side of a right triangle is 2 cm shorter than the hypotenuse which means H - 2
And another side is 7 cm longer than the third side which means H -2 -7 that becomes H - 9
Then according to Pythagoras theorem
[tex]\rm H^{2} = P^{2} +B^{2}[/tex]
Then
[tex]\begin{aligned} \rm H^{2} &= (H-2)^{2} +(H-9)^{2}\\\rm H^{2} &= H^{2} -4H + 4+ H^{2} -18H +81\\ H^{2} -22H + 85 &= 0 \\(H-17)(H-5) &=0\\\end{aligned}[/tex]
Hence the value of H is 17 and 5.
5 is neglected because H - 9 is negative.
So the sides will be 17, 15, and 8.

Please be sure your calculator is set to degrees (not radians) when you do this problem.
(2) Here since P & Q are complimentary it means that their sum is 90 degrees. Since this is a right triangle that means that the remaining angle (R) must be the right angle. See below for a diagram.
sin = opp/hyp. As the sin Q = 9/41 this means that 9 is the length of the side opposite Q (the side PR) and 41 is the length of the hypotenuse. This makes the remaining side (QR) 40 in length.
cos = adj/hyp. If we focus on angle P the side adjacent (next to) is 9 and the hypotenuse is 41. Thus the cos of P = 9/41.
You could have also realized that if P & Q are complimentary the sin P = cos Q and the cos P = sin Q. We were not asked about tangent but it is also the case that tan P = cot Q and cot P = tan Q.

Answer: The correct option is (B) 81°.
Step-by-step explanation: We are given to find the measure of the missing angle of the quadrilateral shown in the figure.
The measures of three angles of the quadrilateral are 65°, 78° and 136°.
To find the value of x, the measure of the fourth angle.
We know that
the sum of the measures of four angles of a quadrilateral is 360°. so, we must have
[tex]65^\circ+78^\circ+136^\circ+x=360^\circ\\\\\Rightarrow 279^\circ+x=360^\circ\\\\\Rightarrow x=360^\circ-279^\circ\\\\\Rightarrow x=81^\circ.[/tex]

To determine whether voters would be willing to vote for a tax increase to improve the city's parks, the park commission surveys 500 park users. Why is this sample likely to be biased?

B. Park users are too busy to be bothered with surveys.
C. There are not enough people in the sample.
D. The entire population of the city was not surveyed.

Step-by-step explanation: Think about the question and what it is asking about, raising taxes to improve the city's parks, now think about who benefits from the parks. Park users right? Okay, but since tax increase will be put on everyone living in the city, some do not use the park. Is it fair to base the survey question just to park users? No, it's biased to base it on park users only. Of course the park users will be okay improving the parks they use. An unbiased survey would ask a sample of citizens in the city whether it's a good idea to raise taxes to improve the city parks.

Answers
.. all real numbers greater than or equal to -2 . . . . the last selection
The range of the function f(x) = |x - 1| - 2 is all real numbers greater than or equal to -2.
Explanation:The function f(x) = |x - 1| - 2 represents the absolute value of x minus 1, subtracted by 2.
The range of the function can be determined by finding the minimum and maximum values it can take.
Since the absolute value of a number is always greater than or equal to zero, the lowest value that f(x) can take is when |x - 1| = 0, which happens when x = 1.
Therefore, the minimum value of f(x) is -2.
As x increases or decreases from 1, the value of f(x) increases.
So, there is no upper bound for the range of f(x).
Therefore, the range of the function is all real numbers greater than or equal to -2.

A photograph measures 12 inches wide by 20 inches long. If the picture is reduced so that the length is 8 inches. What is the new width?
Answers
0.4×12=4.8
The width is 4.8 inches
To find the new width of a photograph after reducing its length to 8 inches, while maintaining the original aspect ratio, set up a proportion based on the original dimensions and solve for the new width, which results in 4.8 inches.
The question involves a proportional reduction of a photograph's dimensions. To determine the new width, we need to maintain the same ratio between the width and the length as in the original photograph. Initially, the photograph measures 12 inches wide by 20 inches long. If reduced so that the length is 8 inches, the width will also reduce in the same ratio.
Let's denote the new width as w. The original ratio is 12/20, which should be equal to the new ratio w/8.
Now, creating a proportion, we have:
12/20 = w/8
By cross-multiplying, we get:
20 × w = 12 × 8
w = (12 × 8) / 20
w = 96 / 20
w = 4.8
Therefore, the new width of the photograph is 4.8 inches.
