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

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

find the measure of angle 1
Answer:
42
Step-by-step explanation:
Angle 1 and the angle that is 138 degrees is on the same line. A line is 180 degrees, so you subtract 138 from 180 and you get 42. I hope this helps (:
Answer:
42 degrees
Step-by-step explanation:
every line is 180 degrees, right, so you need to subtract the number you know another angle to find the missing number.
180-138
42
angle 1 is 42 degrees

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.

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].
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.
