Given f(x) = 1/2(4 – x)2, what is the value of f(16)?
Step-by-step explanation:
Just replace x with 16....
f (x) = 1/2 (4-x) 2
f (16) = 1/2 (4-16) 2
f (16) = (2 - 8) × 2
f (16) = -6 × 2
f (16) = -12

Answer:
The answer could vary. it really just depend on how much of the area he is planning on using.
For all we know, he could use all of either the 15ft or the 3 cm to draw the width.
Answer: The width of 10 lanes in the drawing will be 10 cm
Step-by-step explanation: If 3 cm = 15 ft, divide both sides by 3 to ro finf that 1 cm will represent 5 ft.
If each lane is 5 ft, the width on the drawing will be 1 cm for each lane.
10 lanes will be 10 cm.
And the 60 ft length will be 6 cm in the drawing.

The height of a prism with equilateral triangular base is 25 cm. If the perimeter of the base of the prism is 18 cm, find the volume
Answer:
450[tex]cm^{3}[/tex]
Step-by-step explanation:
The volume of prism is Base times the height.
The Base you count from surface area. The formula is a*b/2. The a is 18/3, because you have the equilateral triangle. So you count 6*6/2 and get 18 square cm.
After that you just multiply 18 and 25 and get 450[tex]cm^{3}[/tex]
I hope this is right
The volume of the prism given with a base of equilateral triangle is 389.71 cm³.
What is the volume of a prism?The volume of a prism is the product of the base area and the height of the prism.
The base of the prism is an equilateral triangle that has a perimeter of 18 cm.
Therefore, each side of the prism is
= (perimeter/3)
= (18/3) cm
= 6 cm
Now, the base area of the triangle is
= (√3/4) × (side)²
= (√3/4) × (6)² cm²
= 9√3 cm²
Now, the volume of the prism is
= base area × height
= 9√3 × 25 cm³
= 225√3 cm³
= 389.71 cm³

A theater group made appearances in two cities. The hotel charge before tax in the second city was $500 higher than in the first. The tax in the first city was 5.5%, and the tax in the second city was 7.5%. The total hotel tax paid for the two cities was $492.50. How much was the hotel charge in each city before tax?
Answer:
The amount before tax at the first hotel be x = $3500
The amount at the second hotel will be x+500 = $4000
Step-by-step explanation:
Let the amount before tax at the first hotel be x
The amount at the second hotel will be x+500
The tax in the first city was 5.5% = 0.055
the tax in the second city was 7.5% = 0.075
Hence, we have
0.055(x) + 0.075(x + 500) = $492.50
0.055x + 0.075x +37.5 = 492.50
0.13x = 492.50 -37.5
0.13x = 455
x = 455/0.13
x = $3500
The amount before tax at the first hotel be x = $3500
The amount at the second hotel will be x+500 = $3500 + $500
= $4000

C. Combinations are difficult to understand.
D. The order does not matter in combinations.
The order does not matter in combinations. is the statement about combinations which is true.
What is Combination?An arrangement of objects where the order in which the objects are selected does not matter.
we need to find the statement which is not true about combinations.
The order matters in some combinations but not in others.
Combinations never happen in real life is a false statement because we can see combinations in real life.
Combinations are difficult to understand is also a false statement because combinations are easy to understand.
The order does not matter in combinations is true because when the order doesn't matter, it is a Combination and When the order does matter it is a Permutation.
Hence, the order does not matter in combinations. is the statement about combinations which is true.

Submit
Reset
Answer:
In the first week, Micah bought 11 gallons of gas.
In the second week, Micah bought 8 gallons of gas.
Step-by-step explanation:
Given:
First week
x gallons of gas at $2.39 per gallon
x gallons = $2.39x
Second week
3 fewer gallons of gas than the first week at $2.49 per gallon
x - 3 gallons = $2.49(x-3)
Total spent = $46.21
$2.39x + $2.49(x-3) = $46.21
2.39x + 2.49x - 7.47 = 46.21
4.88x - 7.47 = 46.21
Add 7.47 to both sides
4.88x - 7.47 + 7.47 = 46.21 + 7.47
4.88x = 53.68
Divide both sides by 4.88
x = 53.68/4.88
= 11
x = 11
First week = x = 11 gallons
Second week
= x - 3
= 11-3
= 8 gallons
Therefore,
In the first week, Micah bought 11 gallons of gas.
In the second week, Micah bought 8 gallons of gas.

The expression 8x+2 factored using the GCF is
The expression 8x+2 factored using the GCF is 2(4x + 1)
Equations are expressions separated by an equal sign
Given the expression 8x + 2
First we need to find the factors of each terms
8x = 2 * 4 * x
2 = 2 * 1
From bot factors, we can see that 2 is common. Factoring out 2 from the expression will give;
8x + 2 = 2(4x + 1)
Hence the expression 8x+2 factored using the GCF is 2(4x + 1)

let f(x) = 2x + 2 write a function g whose graph is a translation 2 units to the right of the graph of f.
Answer:
g(x)=2x
Step-by-step explanation:
A translation of two units to the right basically means -2 so you subtract two from the original equation and get your new equation g(x)=2x.
Geometry// question #8
Answer:
see explanation
Step-by-step explanation:
The translation rule
(x, y ) → (x + 3, y - 2 )
Means add 3 to the original x- coordinate and subtract 2 from the original y- coordinate, thus
A(- 4, 1 ) → A'(- 4 + 3, 1 - 2 ) → A'(- 1, - 1 )
B(1, 1 ) → B'(1 + 3, 1 - 2 ) → B'(4, - 1 )
C(1, - 2 ) → C'(1 + 3, - 2 - 2 ) → C'(4, - 4 )
D(- 4, - 2 ) → D'(- 4 + 3, - 2 - 2 ) → D'(- 1, - 4 )
