g(x)=9x^3-x^2+2 for g(2)
Step-by-step explanation:
g(2)=9.2^3-2^2+2
=18^3-2^2+2
=18^1^4
=18^4
=104,976

38.07 is 9% of what number?
[tex]38.07 = \frac{9}{100} x[/tex]
[tex]38.07 \times \frac{100}{9} = x[/tex]
[tex] \frac{3807}{9} = x[/tex]
[tex]423 = x[/tex]
Answer:
423
Step-by-step explanation:
Use proportions to get (38.07/9) = (x/100). Cross multiply to get 3807 = 9x. Divide 3807 by 9 to get 423.

A hallow metal pipe has an outer diameter of 3 inches and a thickness of 1/4 inch. The length of the pipe is 12 inches. Compute the amount of material needed to make the pipe.
Answer:
Step-by-step explanation:
I don"t really know the answer but i might have and explanation to help. Hollow everyday circular objects appear differently than drawn two-dimensional circles. Objects like pipes and hoses have two different diameters. The outside diameter measures the distance of a straight line from one point on the outside of the object, through its center, and to an opposite point on the outside. The internal diameter measures the inside of the object. Calculating the internal diameter depends on the outside diameter and the thickness of the outer circle.
I need help with the answer
Hi there!
Looking at the graph, we can see zeroes at x = -4, 0 (bounce, degree of 2) and 3. The graph is also face up, so it is positive. We can write an equation in factored form:
f(x) = x²(x + 4)(x - 3)
Find the equation of g by translating each zero left. The new zeros would be:
x = -6, x = -2, and x = 1
Write the polynomial:
g(x) = (x + 2)²(x + 6)(x - 1)
Answer:
f(x)= x²(x+4)(x-3), g(x)= (x+2)²(x+6)(x-1)
Step-by-step explanation:
you have the roots at -4,0, and 3
look at what the graph is doing at those points and see that
-at -4 and at 3 the graph crosses the x-axis so in the equation you will have (x-root)
-at 0 the graph is touching the x-axis and then goes back above/under it so in the equation you will have (x-root)²
f(x)= x²(x+4)(x-3)
g(x) left 2 units
when you move a function to the left/ right you add/subtract that amount to the value of x so
g(x)= (x+2)²(x+2+4)(x+2-3)
g(x)= (x+2)²(x+6)(x-1)

What is the solution set for 7x – 3 = 18, given the replacement set {0, 1,2,3,4} ? O
x = 0
X= 1
X= 2
x= 3
X= 4
Answer:
X = 3
Step-by-step explanation:
Given the expression :7x - 3 = 18
To obtain the solution set ; we solve for X in the equation ;
7x - 3 = 18
Add 3 to both sides
7x - 3 + 3 = 18 + 3
7x = 21
Divide both sides by 7
7x / 7 = 21 / 7
x = 3
Hence, x = 3
Answer:
x=3

All the edges of a cube are expanding at a rate of 4 in. per second. How fast is the volume changing when each edge is 10 in. long
Given:
All the edges of a cube are expanding at a rate of 4 in. per second.
To find:
The rate of change in volume when each edge is 10 in. long.
Solution:
Let a be the edge of the cube.
According to the question, we get
[tex]\dfrac{da}{dt}=4\text{ in./sec}[/tex]
[tex]a=10\text{ in.}[/tex]
We know that, volume of a cube is
[tex]V=a^3[/tex]
Differentiate with respect to t.
[tex]\dfrac{dV}{dt}=\dfrac{d}{dt}a^3[/tex]
[tex]\dfrac{dV}{dt}=(3a^2)\times \dfrac{da}{dt}[/tex]
Putting the given values, we get
[tex]\dfrac{dV}{dt}=(3(10)^2)\times 4[/tex]
[tex]\dfrac{dV}{dt}=3(100)\times 4[/tex]
[tex]\dfrac{dV}{dt}=300\times 4[/tex]
[tex]\dfrac{dV}{dt}=1200\text{ in}^3\text{/sec}[/tex]
Therefore, the rate of change in volume 1200 cubic inches per second.
The length of a vegetable garden is 8 feet more than the width, w. If the area of the garden is 240 square feet, find the width of the garden
Answer:
the width is 30
Step-by-step explanation:
first if the width was there you would multiply it ( the width ) with the length to find the area so you simply do the opposite , divide you should divide 240 with 8 and that's going to make 30 ( the width )
A flamingo's leg length is proportional to its body length. A flamingo with a body length of 1.2 feet has a leg length of 2.5 feet.
Required:
a. Determine to the nearest thousandth the leg length of a flamingo whose body length is 1.4 feet, showing all work.
b. Convert the leg length determined in part A from feet (ft) to centimeters (cm), showing all work. Round the answer to the nearest tenth.
Answer:
a) 3.125feet
b) 95.3cm
Step-by-step explanation:
a) Let the flamingo leg length be l
Let the body length be b
If a flamingo's leg length is proportional to its body length then;
l ∝ b (direct proportionality)
l = kb
k is the constant of proportionality
If a flamingo with a body length of 1.2 feet has a leg length of 2.5 feet, then;
when b = 1.2, l = 2.5
Substitute into the formula
2.5 = 1.2k
k =2.5/1.2
k = 2.083
We ate to find l when b = 1.5
Since l= kb
l = 2.083(1.5)
l = 3.125feet
Hence the leg length of a flamingo is 3.125feet to the nearest thousandths
b) Convert 3.125feet to centimeters
Using the conversion factor
1foot =30.48cm
3.125feet = x
Cross multiply
x = 30.48×3.125
x = 95.25cm
Hence the length length in cm to nearest tenth is 95.3cm
Marissa is tying bows to use as decorations for the holidays. She has 72 ribbon, and each bow requires 2.4 inches of ribbon. How many bows will marissa be able to tie?
Answer:
30 bows
Step-by-step explanation:
I assume there are 72 inches of ribbon...
You divide the total by how much is needed for each, so the expression for this would be 72/2.4
If you simplify this expression, you get 30 bows for your answer.
Checking the answer:
30 bows that each needs 2.4 inches of ribbon would need a total of 30×2.4 inches of ribbon.
30×2.4 = 72, and Marissa has 72 inches of ribbon.
