Answer: [tex]\dfrac{32\pi }{5}\ \text{unit}^3[/tex]
Step-by-step explanation:
Given
The area is bounded by [tex]y=x^2[/tex] and x-axis from [0,2]
The volume generated for [tex]y=f(x)[/tex] when rotated about the x-axis in the interval [a,b] is
[tex]V=\int_a^b\pi y^2dx[/tex]
Insert the values
[tex]\Rightarrow V=\int_0^2\pi x^4dx\\\\\Rightarrow V=\pi \int_0^2x^4dx\\\\\Rightarrow V=\pi \left[ \dfrac{x^5}{5}\right]_0^2\\\\\Rightarrow V=\dfrac{2^5\pi }{5}\\\\\Rightarrow V=\dfrac{32\pi }{5}\ \text{unit}^3[/tex]

A circle has a radius of 1.5 meters.
Find its circumference and area.
help bestiess :)
Answer:
C=9.42
Step-by-step explanation:
Formulas: C=2πr or C=πd
Were gonna use C=2πr
"r"stands for radius from the problem we know that the radius is 1.5 .
Now we substitute the "r" for 1.5, it looks like this C=2π1.5 .
Now we multiply 2x1.5=3 . Now you are left with C=3π
Now you need to multiply 3xπ (Instead of π use 3.14) it would look like this 3x3.14= 9.42
Factor the expression below.
x² - 64
A. (x+3)(x-8)
B. (x-8)(x-8)
C. (x - 16)(x - 4)
D. (x+16)(x-2)
Answer:
(x + 8) (x - 8)
Step-by-step explanation:
To factorise the expression follow the steps:
Think the factorising means you want like:-
( x + _ ) ( x + _ )
Now, add the numbers to get 0 & multiple together to get -64
-64 = 8 x -8
8 + -8 = 0
Now fill the numbers in the factorising mean which will give you,
( x + _ ) ( x + _ ) --> ( x + 8 ) ( x - 8 )
Therefore, the answer will be: ( x + 8 ) ( x - 8 )

Answer:
0
Step-by-step explanation:
If you plug two points into the equation y2-y1/x2-x1, you will find the slope or rate of change. In this case I used the points (0,3) and (2,3). Plug them in to get 3-3/2-0. 0/2=0. Therefore, the rate of change is 0.
If this helps please mark as brainliest
Answer:
0
Step-by-step explanation:
there is no rate of change. rate of change means what is the slope or the distance the beginning and end of the line. since it is going in a straight line there is no rate of change.

if 3 tacos at taco el primo cost $5.31, how much would 8 tacos cost?
Answer:
[tex]\$14.16[/tex]
Step-by-step explanation:
Since the question implies a constant rate, we can set up the following proportion:
[tex]\frac{3}{5.31}=\frac{8}{x},\\3x=8\cdot 5.31,\\x=\frac{8\cdot 5.31}{3}=\boxed{\$14.16}[/tex]
3t = 5.31
t = 1.77
We're looking for 8t.
t = 1.77
8t = 14.16

A recipe for peanut butter cookies uses only peanut butter ,sugar ,syrup and egg in the ratio 5:4:2:1
A) wants to makes 2.4kg of cookies
How much of each ingredient should he use.
B) using this recipe 10ph of syrup is needed to make 15 of these cookies
A)butter= 12
sugar = 9.6
syrup= 4.8
eggs= 2.4
What is ratio?A ratio indicates how many times one number contains another.
Given:
5:4:2:1
Let the common ratio be x
So, butter= 5x
sugar= 4x
syrup = 2x
egg= x
As, eggs= 2.4 kg
So, x= 2.4
Now,
butter= 5x = 5* 2.4 = 12
sugar= 4x = 4* 2.4 = 9.6
syrup = 2x = 2* 2.4 = 4.8

the public school enrollment of a city is 13,500. Enrollment is declining at a rate of 4.5% per year. predict the enrollment in 5 years.
Answer:
The enrollment after 5 years is 10,724
Step-by-step explanation:
Generally, we can have the depreciation formula written as follows;
A = P(1 - r)^t
A is the number of enrollment in after a certain number of years t
P is the initial population which is 13,500
r is the rate of depreciation which is 4.5% = 4.5/100 = 0.045
t = 5 years
Substituting these values, we have it that;
A = 13,500(1-0.045)^5
A = 10,723.84
Solve for X
x = ___ (Round to the nearest hundredth)
Answer:
12.62
Step-by-step explanation:
imagine a circle with the center at the corner (let's call it A) with the 31 degree angle. the radius is AB.
so,
x = sin(31)×AB
and
21 = cos(31)×AB
therefore,
AB = 21/cos(31) = 24.4993...
=> x = sin(31)×24.4993... = 12.62 (12.61807...)

What is the ratio of the side length of the smaller square to the side length of the larger square?
FAST RESPONSE PLEASE!!!
Answer:
the smaller square length is 3cm
the larger square length is 6cm
hence their ratio will be 3:6
Simplify the ratio
we have our final answer to be 1:2
The required ratio of the side length of the smaller square to the side length of the larger square is 1 : 2.
The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Here,
Side of smaller square, a = 3
Side of the larger square, b = 6
According to the question,
The ratio of the side length of the smaller square to the side length of the larger square,
= a / b = 3 / 6
= 1 / 2
Thus, the required ratio of the side length of the smaller square to the side length of the larger square is 1 : 2.

Help, I dont get it, Like how do I do the division?
Answer:
Step-by-step explanation:
you actually dont have to do any division in this problem. since you know the area of the square and its depth, you simply multiply to two fractions, so [tex]\frac{25}{4} *\frac{8}{5}[/tex] when you multiply fractions all you do is multiply the tops and and bottoms, so 25 * 8=200 and 5 * 4=20, so the fraction is now 200/20, so when divide both sides by 20, the answer is 10. another way to demonstrate this in case you didnt understand is that you can rewrite your equation as [tex]\frac{25 * 8}{4 * 5}[/tex] then all you have to do is perform the opperation.

Shows the termination of the parking lot of Helen healings health food store parking lot is how many square yards
Answer:
1100 yd²
Step-by-step explanation:
The parking lot can be divided into 2 rectangles :
Area of a rectangle = Length * Width
First rectangle :
Dimension = 40 yards by 20 yards
Area = 40 * 20 = 800 yd²
Rectangule 2 :
30 yards by 10 yards
Area = 30 * 20
Area = 30 * 10 = 300 yd²
Total area of parking lot :
800 + 300 yd²
= 1100 yd²
