The height of water shooting from a fountain is modeled by the function f(x) = -4x2 + 24x - 29 where x is the distance from the spout in feet. Complete the square to determine the maximum height of the path of the water.
Step-by-step explanation:
f(x) = -4x^2+24x-29
= -4(x^2-6x)-29
= -4(x-3)^2 -4(-9) -29
= -4(x-3)^2 +36-29
= -4(x-3)^2 +7
maximum height = 7m

The cost of shipping a package overnight from San Antonio to Dallas is $5.50 plus $0.85 per ounce. Which function rule could you use to find
the cost to ship a package that weighs x ounces?
c(x) = 5.50x + 0.85
c(x) = 0.85x + 5.50
c(x) = 5.50 - 0.85x
c(x) = (0.85 +5.50)x
Answer:
B
Step-by-step explanation:
5.50+0.85x=
The function rule to find the cost to ship a package that weighs [x] ounces is c[x] = 0.85x + 5.5.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is the cost of shipping a package overnight from San Antonio to Dallas, which is $5.50 plus $0.85 per ounce.
We can write -
Fixed cost of shipping overnight = $5.50
Cost per ounce for shipping = $0.85
The function rule that could be used to find the cost to ship a package that weighs [x] ounces will be -
c[x] = 0.85x + 5.5
Therefore, the function rule to find the cost to ship a package that weighs [x] ounces is c[x] = 0.85x + 5.5.

Given the function h(x)=-4+6,
Find the value of h(-2)
h(x) = -4 + 6
h(x) = 2
h(-2) = 2 because It's a constant function, when you substitute any x-values, you still get the same y-value.
Even if you substitute x = 1000, you still get y = 2.
Therefore, h(-2) = 2
-----------
If you mean h(x) = -4x+6
then h(-2) = 8+6 = 14
therefore, h(-2) = 14 for h(x) = -4x+6

The equation below shows the cost, in dollars, of a T-shirt, selling at $12.00, and 3 pairs of socks. What is the cost of one pair of socks, s? 12 + 3s = 42
Answer:
The answer is one pair of socks = $10
Step-by-step explanation:
I subtracted 42 by 12 and got 30. I then divided 30 and 3 and got 10.
42-12=30
30/3=10
Or you can subtract 12 from both sides to get the variable on one side. Then you divide the variable by the coefficient (3) and divide 30 by 3 to get 10.

A cheetah can run 97 km/hour. How fast can it run in 90 seconds? Round your answer
to the nearest hundredth.
The cheetah can run 2.42 km in 90 seconds
Calculating distanceFrom the question, we are to determine how fast the cheetah could run in 90 seconds
First, we will convert the speed to meter/seconds
The given speed = 97 km/hour
97 km/ hour = (97 × 1000 /3600) m/s
97 km/hours = 26.9444 m/s
Now, using the formula,
Distance = Speed × Time
From the given information,
Time = 90 seconds
∴ Distance = 26.9444 × 90
Distance = 2424.996 m
Distance = 2.424996 km
Distance ≅ 2.42 km
Hence, the cheetah can run 2.42 km in 90 seconds

What is the equation of the line that is perpendicular to the line y equal minus 1 over 2 open parentheses x minus 18 close parentheses and intersects the y-axis at open parentheses 0 comma space minus 1 close parentheses ?
Given:
The equation of line is
[tex]y=-\dfrac{1}{2}(x-18)[/tex]
The perpendicular line intersect the y-axis at (0,-1).
To find:
Equation of perpendicular line.
Solution:
Point slope form of a line is [tex]y-y_1=m(x-x_1)[/tex], where m is slope.
We have,
[tex]y=-\dfrac{1}{2}(x-18)[/tex]
Thus, the slope of this line is [tex]m_1=-\dfrac{1}{2}[/tex].
Product of slopes of two perpendicular lines is -1.
Let the slope of perpendicular line is [tex]m_2[/tex]. Then,
[tex]m_1\times m_2=-1[/tex]
[tex]-\dfrac{1}{2}\times m_2=-1[/tex]
[tex]m_2=2[/tex]
Slope of perpendicular line is 2 and it passes through (0,-1). So, the equation of perpendicular line is
[tex]y-(-1)=2(x-0)[/tex]
[tex]y+1=2x[/tex]
[tex]y=2x-1[/tex]
Therefore, equation of perpendicular line is [tex]y=2x-1[/tex].
