I kept getting the answer 401.92 and says it’s not correct, am I doing something wrong? This is what I did
V= π 4^2(8)
V= π 16(8)
V= π 124
V= 3.14 • 124 = 401.92
Reply with reasoning.
Answer:
v=pie r² ×h
v=3.14×2²×8
v= 100.48
Step-by-step explanation:
you are using diameter as the radius that is why exactly you are not getting it right! divide the diameter by 2 to get radius and use it with the formula
9. A population of bears decreases exponentially. 400 a. What is the annual factor of decrease for the bear population? Explain how you know. 300 bear population 200 100 b. Using function notation, represent the relationship between the bear population, b, and the number of years since the population was first measured. I. That is, find a function, . so that b = f(t). 2 3 4 5 years since 2010 (From Unit 5, Lesson 8.) 10. Equations defining functions ab.c.d. and are shown here. Select all the equations that represent exponential functions. A. a(x) = 2x B. b() = (?) Ccm) = 2" D. dx) = 32 E. (t) = 3.2
Answer:
9a. 0.8
9b. f(t) = 400(0.8^t)
10. B, C, E
Step-by-step explanation:
The growth factor (or factor of decrease) for a time period will be found by taking the ratio of the value at the end of the time period to the beginning value.
9a.The population is 320 after 1 year. It started at 400 at the beginning of the year, so the factor of decrease is 320/400 = 0.80.
b.The exponential function can be written as ...
f(t) = a·b^t . . . . . where 'a' is the initial population, and 'b' is the factor of decrease
The initial population is shown on the graph as 400; the factor of decrease is what we just computed.
f(t) = 400(0.80^t)

2. Find the circumference?
I need help I don’t know if that is the right answer
Answer:
50.24 cm
Step-by-step explanation:
circumference = 2πr
circumference = 2 × 3.14 × 8 cm
circumference = 50.24 cm
Remember to include cm in the answer. It should read 50.24 cm.
You got it right. Good job!
Which of the following functions best describes this graph?
We see that the zeros of the function are 4 and 5.

Jane made a poster that had a length of feet and a width of feet. What is the perimeter of her poster?.
Answer:
Im not completely sure what this question is asking, however I'll try...
Well, if the length is in feet and the width is in feet, that would conclude that the perimeter would also be in feet. If you're asking for the actual number answer for what the perimeter is, I will not be able to help since there is a lack of information; you can only determine the perimeter when given the exact number of feet, both the width and length are.
Step-by-step explanation:
If f(1) = 0, what are all the roots of the function f (x) = x cubed 3 x squared minus x minus 3? Use the Remainder Theorem. X = –1, x = 1, or x = 3 x = –3, x = –1, or x = 1 x = –3 or x = 1 x = –1 or x = 3.
All the roots of the provided function If f(1) is equal to the zero are -3, -1 and 1.
What is polynomial?
Polynomial equations is the expression in which the highest power of the unknown variable is n (n is real number).
The function given in the problem is,
[tex]f(x)=x^3+3x^2-x-3[/tex]
If f(1) = 0
[tex]f(1)=(1)^3+3(1)^2-(1)-3\\f(1)=1+3-1-3\\f(1)=0[/tex]
Thus, (x-1) is one of the factor of polynomial. Equate the polynomial equal to the zero, to find other roots as,'
[tex]x^3+3x^2-x-3=0\\x^2(x+3)-1(x+3)=0\\(x+3)(x^2-1)\\(x+3)(x+1)(x-1)=0[/tex]
Equate all the groups to zero to find the roots as,
[tex]x+3=0, x=-3\\x+1=0, x=-1\\x-1=0, x=1[/tex]
Hence, all the roots of the provided function If f(1) is equal to the zero are -3, -1 and 1.

Answer: The equation for a straight line is a linear equation. Since linear usually stands for anything straight or in a line, thus the equation for lines in the XY plane is referred to be a linear equation. For example, 2x+3y = 5 is a linear equation in two variables.

Last week the price of gas was $2. 25. This week, the price has decreased by 15%. What is the price of gas this week
Answer:
$ 1.9125
Step-by-step explanation:
price of gas last week= $2.25
15% of $2.25 = 15/100 × 2.25
= $0.3375
since the price of the gas decreased by 15% this week, the new price will be 2.25- 0.3373 =$1.9125.
Factor the following polynomials by finding a GCF
Answer:
Step-by-step explanation:
To factor out a GCF from a polynomial we first need to identify the GCF of all the terms, this is the part that goes in front of the parenthesis, then we divide each term by the GCF, the answer is what is left inside the parenthesis. This is shown in the following examples Example 3. 4x2−20x+16 4x2 −20x16GCF is4, divide each term by4
