f(3)=
f(-4)=
please give working for better understanding
Answer:
46 and 277
Step-by-step explanation:
Given
f(x) = [tex]x^{4}[/tex] - 8x - 11 ← substitute x = 3, x = - 4 into f(x)
f(3) = [tex]3^{4}[/tex] - 8(3) - 11 = 81 - 24 - 11 = 81 - 35 = 46
f(- 4) = [tex](-4)^{4}[/tex] - 8(- 4) - 11 = 256 + 32 - 11 = 288 - 11 = 277

Explain why the exponents cannot be added in the product 12^3 x
11^3.
Answer:
see explanation
Step-by-step explanation:
The exponents can only be added if the bases are the same
Here one base is 12 and the other is 11
So the rule of addition is not applicable.
Answer:
Because the bases (12 and 11) are different.
Step-by-step explanation:
You can only add exponents when the bases are the same.

A 480 people
B 425 people
C 324 people
D) 32 people
Answer:
324 people, C
Step-by-step explanation:
You first make 60 percent a decimal by moving the deciaml point up two digits, which makjes the number .60. Then, multiply 540 x .60 which gets your 324.

A construction worker drops a wrench from a height of 484 feel the function
h =
16x
+ 484 gives the height h of the wrench after a seconds When does the wrench hit the ground?
The wrench hits the ground blank
seconds after it is dropped
Answer:
30.25 seconds
Step-by-step explanation:
If you want to find the time at which the wrench hits the ground, you must recognize that the height of the wrench is 0 feet. If h represents the height, then 0 can be plugged in for h. The equation is now 0=16x+484. You then must subtract 484 from both sides, giving you -484=16x. You then divide both sides by 16 to give you x by itself. -484/16=-30.25. Because this is dealing with time and negative time does not exist, the negative sign on the 30.25 can be neglected.

Genny is arranging flowers in vases for every 1 rose shes uses 6 tuilps .How many tulips would she use for every 5 roses
Answer:
30
Step-by-step explanation:
Ah okay, so this is a simple proportion.
If 1 rose = 6 tulips, then you just multiply however many roses you have by 6. So in your case, 5 x 6 = 30. So in short, for every 5 roses Genny uses, she will use 30 tulips.
Answer:
30 tulips
Step-by-step explanation:
This question gives us the amount of tulips for one rose.
Let us make 1 rose as r and a tulip is t. Now write an equation for the tulips.
Tulip = 6r
If we have 5r:
5r = 6t x 5
Solve!
5r = 30t
5 roses = 30 tulips
Hope this helps :)
What is the equation of the line that passes through (4, 3) and (-4, -1)?
y = 2 x + 7
y = + 1
2 x + 1
y = + 7
Answer:
Step-by-step explanation:
First find the slope of the line
(4 , 3) ; x₁ = 4 ; y₁ = 3
(-4,-1) ; x₂ = -4 ; y₂ = -1
slope [tex]= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\[/tex]
[tex]=\frac{-1-3}{-4-4}\\\\=\frac{-4}{-8}\\\\=\frac{1}{2}[/tex]
m = 1/2 , and take any one point (4 , 3)
y -y1 = m(x - x1)
[tex]y - 3 = \frac{1}{2}(x - 4)\\\\y -3 = \frac{1}{2}x-4*\frac{1}{2}\\\\y - 3 =\frac{1}{2}x - 2\\\\y = \frac{1}{2}x - 2 + 3\\\\y =\frac{1}{2}x + 1[/tex]
