Step-by-step explanation:

To help you, Remeber the SOHCAHTOA rule

When It asked to find sin, cos, tangent of a angleIf you finding the sin of a angle you must find the side that is Opposite then put it over the hypotenuse I'll do 3,6,7,8 for you.

For 3,The side that is opposite of c is 28 and the hypotenuse (which is the longest side of the triangle) is 35. So the answer is 28/35. or 4/5.

For 6, 32 is opposite of A and 40 is the hypotenuse so

32/40 or 4/5 is our answer.

For 7, 24 is opposite of Z and 40 is the hypotenuse so

24/40 or 3/5 is the answer.

For 8, 14 is opposite of Angle C and 50 is our hypotenuse so

14/50=7/25 is our answer

COS

To find cos it is adjacent/hypotenuse

For 2 the adjacent side to C is 16 and the hypotenuse is 34. so our answer is 16/34 or 8/17.

For 5, the adjacent side is 30 and the hypotenuse is 34 so our answer is 30/34 or 15/17

For 9, the adjacent side is 24 and hypotenuse is 30 so our answer is 24/30 or 5/6.

TAN

TO FIND TAN, it is Opposite/Adjacent

4, the opposite side is 32 and the adjacent is 24 so our answer is 32/24 or 4/3.

10, the opposite side is 27 and the adjacent is 36 so our answer is 27/36 or 3/4

Answer from: Quest

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where, $a = \frac{\sum y \sum x^2 - \sum x\sum xy}{n\sum x^2 - (\sum x)^2}$

here given table is,

price ($), x : 18 23 25 29 30 33

pairs sold, y : 16 13 10 8 6 2

so, $\sum x = 158$ , $\sum y = 55$ , $\sum xy = 1315$ ,

$\sum x^2 = 4308$ and $\sum y^2 = 629$ ,

thus, slop of the given line is,

$a = \frac{55\times 4308-158\times 1315}{6\times 4308-(158)^2}$

⇒ $a = \frac{29170}{884}$

⇒ $a =32.9977375566$ ≈ 33

Answer from: Quest

pretty sure its b

step-by-step explanation:

why? because i noticed a pattern. 60 120. those numbers without the zero, make the 6 times tables leaving your answer to be b since 6 times 4 is 24 and adding a zero making it 240.
