Answer:
4x² + 4x + 1
Step-by-step explanation:
to evaluate (g ￮ f)(x) , substitute x = f(x) into g(x)
g(f(x))
= g(2x + 1)
= (2x + 1)² ← expand using FOIL
= 4x² + 4x + 1

If you have a distribution of 100 scores, and you want 20 intervals, what should be the size of your class interval
Answer:
5
Step-by-step explanation:
You simply just divide 100 by 20 and get your answer which is 5.
When you distribute something, you are dividing it into parts. In math, the distributive property helps simplify difficult problems because it breaks down expressions into the sum or difference of two numbers

Use the Unit Circle to find the exact value of the inverse trig function.
Answer:
330
Step-by-step explanation:
When we are at 30 degrees on the unit circle, we are at the point ([tex]\sqrt3[/tex]/2, 1/2) so if we go to -30 degrees (330 degrees), we will be at point (-[tex]\sqrt3[/tex]/2, -1/2).

Find the area of the shaded region.
Step-by-step explanation:
total area
20 × 17 = 340cm²
unshaded region
9 × 6 = 54cm²
area of shaded region
340 - 54 = 286cm²
What is the area of this shape
Answer:
63
Step-by-step explanation:
Calculate the area of the rectangles separately. The bottom rectangle is [tex]6\cdot 8=48[/tex] [tex]\text{in}^2[/tex] and the top one is [tex]3\cdot 5=15[/tex] [tex]\text{in}^2[/tex]. Adding, the total area is 48 + 15 = 63 [tex]\text{in}^2[/tex].
Which of the following ratios is equal to 5 to 30?
Answer:
D
Step-by-step explanation:

PLS GIVE WORKING OUT
THANKS :)
Answer:
for a three hour job it would be £105

to find how much he charges an hour, we divide 140 by 4 and get 35.
from there we multiply 35(£) by 3(hours) and get 105(£).
What is the horizontal and vertical shift for the absolute value function below?
f(x) = |x -5|+ 1
Answer:
Moving to the right by 5 units
Moving up by 1 unit
Step-by-step explanation:
The basic absolute value function is f(x) = |x|
The graph vertex is at the origin.
Adding a value inside the absolute value brackets changes the vertex of the graph horizontally.
Adding a term moves it to the leftSubtracting a term moves it to the rightAdding a value outside the absolute value brackets changes the vertex vertically.
Adding a term moves it upSubtracting a term moves it downHere, in the absolute value, we are subtracting by 5, so we move to the right 5
Outside the brackets, we are adding 1, so we move up 1.

Imagine the following scenario: A student is about to take the final exam and has completed all assignments except the final exam. Out of 100 possible Project Assignment points, they have received 61 points. Out of 100 possible Quiz points, they have received 54 points If the student wanted to receive an overall B grade in the class, what do they need to score on the final exam? Give your answer as a percentage rounded to the nearest for decimal place (no percentage sign necessary), e.g., if I calculated 99.68%. I would enter 99.7.
Project Assignments: 60%
quizzes: 10%
final exam:30%
Answer:
126.7 if B=80
93.3 if B=70
Step-by-step explanation:
Let F represent the student's score on the final exam, and let B represent the percentage required for a grade of B. Then we must have ...
0.60(61) +0.10(54) +0.30F = B
B = 0.30F +42
F = (B -42)/0.3
__
If a grade of B requires 80 points or more, then the required grade on the final is ...
F = (80 -42)/0.3 = 38/0.3 = 126 2/3
The student must get 126.7% on their final to achieve an overall average of 80.
__
If a grade of B requires 70 points or more, then the required grade on the final is ...
F = (70 -42)/0.3 = 28/0.3 = 93 1/3
The student must get 93.3% on their final to achieve an overall average of 70.
Find the volume of a sphere with a radius of 7.5 inches. Give your answer in terms of u.
Answer:
1767.15cm^3
Step-by-step explanation:
volume of a sphere is V= 4/3 *pi* r^3
and pi is 22/7 or 3.142
and the value for r is 7.5
therefore v is 4/3 *3.142*7.5^3
v= 1767.15

nine times a number y plus seven is equal to a number y . Write the word sentence as an equation.
PLZ HELP
Answer: 9y + 7 = y
Explanation:
The phrase, "nine times a number y" is "9y" in the form of an equation. When any term is by a number, they are meant to be multiplied together. So, "9y" means "9 times y".
The phrase, "plus seven" simply means to add seven.
The phrase, "equal to number y" is "= y" because "number y" refers to that term.
And so, all together, you get 9y + 7 = y.
(Brainliest would be appreciated)
