Answer:
There are 40 problems on the test
Step-by-step explanation:
Let p = the number of problems on the test

In a unit circle, 0 = 360°. What is the terminal point?
Answer:
The terminal point would be (1,0)
Step-by-step explanation:
Recall that in a unit circle, x° is located at the point (cosx°,sinx°) therefore the terminal point would be (cos(360°),sin(360°)) -> (1,0)
In a unit circle, it is given that 0 = 360°. The terminal point would be equal to (1,0).
what is the terminal point?The circle unit terminal Points in the unit circle to locate the terminal point, begin with (1,0).
In a unit circle, x° is located at the point (cosx°,sinx°)
In a unit circle, 0 = 360°.
therefore the terminal point would be
(cos(360°),sin(360°)) -> (1,0)

A professor wants to determine the best way to present an important topic to his class. He has the following three choices: he can lecture, he can lecture plus assign supplementary reading, or he can show a film and assign supplementary reading. He decides to do an experiment to evaluate the three options. He solicits 15 volunteers from his class and randomly assigns 5 students to each of the three conditions. The students were subsequently tested on the material. The following scores (percentage correct on the test) were obtained:
LECTURE Lecture + Reading Film + Reading
92 86 81
86 93 80
87 97 72
76 81 82
80 94 83

This is the floor plan of jack's toy room. Jack needs to determine the area of the floor so he can order new flooring. Enter the area, in square feet, of Jack's toy room floor.
Answer:
205.75
Step-by-step explanation:
first, separate the floor into 3 different rectangles to calculate the area and then add them together.
area of rec=L*B
rec 1: 11.5*8=92
rec 2: (12.5-5)*(18.5-8-7)=26.25
rec 3:7*12.5=87.5
Then:
92+26.25+87.5=205.75

Answer:
x^2+7x +49/4 and (x+7/2)^2
x^2+bx +b²/4 and (x+b/2)^2
Step-by-step explanation:
Given the expression
x^2+7x+c
We need to find the constant that completes the expression
Take the half of the cpeffiecient of x = 7/2
Taking the square of the result
Square of the result = (7/2)^2
Hence c = (7/2)^2
The expression becomes;
x^2 + 7x + (7/2)^2
= x^2+7x +49/4
= (x+7/2)^2
For x^2+bx+d
We need to find the constant that completes the expression
Take the half of the cpeffiecient of x = b/2
Taking the square of the result
Square of the result = (b/2)^2
Hence d = (b/2)^2
The expression becomes;
x^2 + bx + (b/2)^2
= x^2+bx +b²/4
= (x+b/2)^2

obtuse scalene triangle
Step-by-step explanation:
All angles in a triangle add up to 180°.
[tex]3x-5+x+10+x=180[/tex]
[tex]5x+5=180[/tex]
[tex]5x=175[/tex]
[tex]x=35[/tex]
So, x=35.
When we plug in x to each angle, we see that the 3x-5 angle is above 90°, and all of the angles are different. So, this is an obtuse scalene triangle.
