Answer:
The inverse function is C (H) = H+10.53/2.15. The approximate head circumference of a child who is 26 inches tall is 16.99 inches.
Step-by-step explanation:
Using the inverse function, the head circumference of a child who is 26 inches tall is;
16.99 inches
We are given the function;
H(C) = 2.15C - 10.53
Where;
H s height of the child
C is head circumference of a child the
To get the inverse of the function, we will make C the subject to get;C(H) = (H + 10.53)/2.15
At H = 26 inches, we have;
C(26) = (26 + 10.53)/2.15
C(26) = 16.99 inches

Answer:
The answer to the question provided is 16 units.
.
Step-by-step explanation:
☆Well, we simply use the distance formula, which is:
[tex]d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2} }[/tex]
...
☆All we need to do is plug in!
[tex]d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2} } \\ \\ d = \sqrt{(9 - 25) {}^{2} + (12 - 12)^{2} } \\ d = \sqrt{( - 16)^{2} + (0) ^{2} } \\ d = \sqrt{256 + 0} \\ d = \sqrt{ 256 } \\ d = 16[/tex]

at a sale, dresses sold for 22.00 each. This price was 55% of a dress's original price.
Answer:
22.00x55%=12.10. 22-12.10=9.90
Answer:
$40
Step-by-step explanation:
22/55 = dollar per percent
dollar per percent = 0.4
0.4 x 100 will equal to 100% of the original price
0.4 x 100 = 40
to check, 40 x 55% = 22

Damon's father pays him one dollar to start the work and
doubles his pay for each hour of work. Write a function that
models this situation.
Answer: p(x) = $1*(2)^x
Step-by-step explanation:
First, the father pays him $1 for only starting the work, and for each hour, the payment is doubled.
So after the first hour, the payment wil be 2*$1 = $2.
After the second hour, the payment will be 2*(2*$1) = $1*(2)^2
After another hour, the payment will be 2*($1*(2)^2) = $1*(2)^3
We already can see the pattern here, after x hours, the payment will be:
p(x) = $1*(2)^x
This is the function that models this situation.
Solve for x in this inequality: -13 < 3x – 7 < 5
-13 < 3x – 7 < 5
Add 7 to all 3 terms;
-6 <3x<12
Divide all 3 terms by 3:

Coffee costs $3.59 per pound. How much would 5.7 pounds of coffee
cost?
Answer:
20.463
Step-by-step explanation:
3.59x5.7
5.7 pounds of coffee would cost $20.463.
What is simplification?When a mathematical expression is converted into an equivalent, typically shorter statement, it becomes simpler. Procedure simplification is one method to encourage uniformity in work effort, expense, and duration. It reduces diversity and variation that is detrimental, pointless, or unnecessary.
Given, Coffee costs $3.59 per pound. Since,
1 pound of coffee costs = 3.59$
5.7 pounds of coffee costs = 3.59 * 5.7
5.7 pounds of coffee costs = 20.463
Therefore, $20.463 would be the cost of 5.7 pounds of coffee.

Given the Vertex (1,0) and the Directrix y = -¼, find the equation of the quadratic
(x - 1)2
(x + 5)2
2(x - 1)2
-x2 - 1
Answer:
y = (x - 1)²
Step-by-step explanation:
A parabola is the locus of a point such that its distance from a fixed point (known as the focus) and a fixed line (known as the directrix) is always constant. The equation of a parabola is a quadratic equation.
The equation of a parabola with a horizontal directrix is given by:
(x - h)² = 4p(y - k).
Where the directrix (y) = k - p, vertex = (h, k)
Given that: Vertex (1,0) and the Directrix y = -¼, Therefore:
vertex = (h, k) = (1, 0). h = 1 and k = 0.
y = k - p
but y = -1/4. Hence:
-1/4 = k - p
p = k + 1/4
p = 0 + 1/4
p = 1/4
Since the equation of the parabola is:
(x - h)² = 4p(y - k).
Substituting:
(x - 1)² = 4(1/4)(y - 0)
(x - 1)² = y
y = (x - 1)²
y = x² - 2x + 1
