Answer: A
You already know that the y-intercept in -32 for every equation by plugging in 0 for x, so disregard the coordinate (0,-32). Plug in -2 and 4 as your x values and check if they are equal to your y-value 0.
The correct answer is A. +3, unless inside parentheses, indicates a positive vertical change, thus the function would move upward. If the function looked like 2(x^3 + 3) the change from the +3 would be horizontal (left) instead.
Answer:
The answer is y= -1/3x-5
Step-by-step explanation:
(9, -8) and (-6, -3)
m= y²-y¹/x²-x1
m= (-3)-(-8)/(-6)-9
m= 5/-15
m=-1/3
y=mx+b
y=-1/3x+b
-3=-1/3(-6)+b
-3=2+b
-2 -2
-5=b
The answer is y=-1/3x-5
Answer:
B) 2771 cubic centimeter
Step-by-step explanation:
first find the volume of the cylinder
V=πr^2h
V=3.14*7^2*26
V=4002.39
then find the volume of the cone
V=πr^2h
/3
V=3.14*7^2*24/3
V=1231.5
subtract the volume of the cone from the cylinder
4002.39-1231.5
2770.89
round to the nearest whole number
2771
Answer: The first option.
Step-by-step explanation:
1. To solve this exercise you need to remember that:
- An even function is a function with the following property:
f(-x)=f(x)
- An odd function is a function with this property:
f(-x)=-f(x)
2. By definition, the contangent is an odd function, therefore you have that:
cot(-θ)=-cot(θ)
Then:
3. So, you can coclude that the first step is wrong. Therefore, the answer is the first option.
