What is the inverse of the function h(x) =3/2(x-11)
Answer:
Step-by-step explanation:
Answer:
[tex]h^{-1}[/tex](x) = [tex]\frac{2}{3}[/tex] x + 11
Step-by-step explanation:
let y = h(x) and rearrange making x the subject , that is
y = [tex]\frac{3}{2}[/tex] (x - 11 ) ← multiply both sides by 2 to clear the fraction
2y = 3(x - 11) ← distribute
2y = 3x - 33 ( add 33 to both sides )
2y + 33 = 3x ( divide all terms by 3 )
[tex]\frac{2}{3}[/tex] y + 11 = x
Change y back into terms of x with x = [tex]h^{-1}[/tex](x) , thus
[tex]h^{-1}[/tex](x) = [tex]\frac{2}{3}[/tex] x + 11

a speedboat that costs $45,000 is depreciating at a rate of 20% per year. Find the value of the boat after 4 years.
Answer:
$18,432
Step-by-step explanation:
After the first year, the speedboat is now worth $36,000 because 20% of 45,000 is 9,000, and 45,000 - 9,000 = 36,000. After the second year, it is now worth $28,800. After the third year, it is worth $23,040 since 20% of 28,800 is 5,760 and 28,800 - 5,760 = 23,040. After four years, the boat that once was worth $45,000 is now worth $18,432.
After 4 years, the value of boat is $9,000.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
We have to given that;
A speedboat costs $45,000 is depreciating at a rate of 20% per year.
So, The depreciating amount after one year = 20% of $45,000
= 20/100 × 45,000
= $9,000
Thus, The value of boat after 4 years = $45,000 - 4 × $9,000
= $45,000 - $36,000
= $9,000

what is the y-value of the solution to the system?
Answer:
y=7.51
Step-by-step explanation:
First, you have to simplify one of the equations down
3x-y=4
y=-4+3x
Second, you insert the value of y into the other equation and then solve for x
9x+5(-4+3x)=8
9x-20+15x=8
24x=28
x=1.17
Last, insert the value of x into the original equation and then solve for y
y=4+3(1.17)
y=7.51

Solve: 8- (y + 3) = 11
y = 6
y = 3
y=0
y = -6
Answer:
y = - 6
Step-by-step explanation:
Given
8 - (y + 3) = 11 ← distribute and simplify left side
8 - y - 3 = 11
5 - y = 11 ( subtract 5 from both sides )
- y = 6 ( multiply both sides by - 1 )
y = - 6

Find the area of △ABF. Round the area to the nearest whole number, if necessary.
Answer:
Area of ΔABF = 6 square units
Step-by-step explanation:
A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The area of the ΔABF is 6 units².
What is a triangle?A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°.
To find the area of the ΔABF, we need to find the length of the base and the altitude of the triangle. Therefore, we can write the lengths as,
Base, FA = [tex]\sqrt{[-5-(-2)^2]+[4-1]^2}[/tex]
=√[(-5+2)² + (3)²]
= √[(-3)² + (3)²]
= √(9 + 9)
= √18
= 3√2
Altitude, BF = [tex]\sqrt{[0-(-2)^2]+[3-1]^2}[/tex]
=√[(0+2)² + (2)²]
= √[(2)² + (2)²]
= √(4 + 4)
= √8
= 2√2
Now, the area of the triangle can be written as,
Area of the triangle = (1/2) × Base × Altitude
= 0.5 × 3√2 × 2√2
= 6 units
Hence, the area of the ΔABF is 6 units².

What is the mean absolute deviation? Round to the nearest tenth.
Answer:
The mean absolute value is 7.7, when rounded to the nearest tenth.
Step-by-step explanation:
1.) To get the mean absolute deviation you have to find the mean first:
32 + 35 + 20 + 16 + 28 + 13 = 144 ÷ 6 = 242.) Then, you have to find the difference of each element in your data set that is away from the mean. Then, you have to find the absolute values of the answers:
32 - 24 = | 8 | → 835 - 24 = | 11 | → 1120 - 24 = | -4 | → 416 - 24 = | -8 | → 828 - 24 = | 4 | → 413 - 24 = | -11 | → 113.) Then, you have to find the mean of the absolute values:
8 + 11 + 4 + 8 + 4 + 11 = 46 ÷ 6 = 7.6666666666666666666666666666667 = 7.7Answer:

determined the daily water intake is about 15.5 cups for males per day
How much water should a young man drink per day in liters?
4 cups = 1 qt, 1.06 gts = 1 L
Greetings from Brasil...
According to the annex, we note that
1 qt = 1 quart = 0.95L
To solve this problem, just apply some rules of 3.....
1st - how many qt's are in 15.5 cups
qt cup
1 ---------- 4
X ---------- 15.5
4 · X = 1 · 15.5
4X = 15.5
X = 15.5 ÷ 4
X = 3.875qt
Last rule of 3 to know how many liters there are in 3.875qt:
qt litres
1 ---------- 0.95
3.875 ---------- Y
1 · Y = 0.95 · 3.875
Y = 3.68LIn a day a young man should drink 3.68L of water
