The shape of an underground pool follows a parabola with the function LaTeX: f\left(x\right)=x^2+8xf ( x ) = x 2 + 8 x. What point represents the bottom of the pool? Group of answer choices
Answer:
The point that represents the bottom of the pool is [tex](x,y) = (-4, -16)[/tex].
Step-by-step explanation:
Given that the shape of the underground pool is a parabola, that is, a second order polynomial. Then, the point that represents the bottom of the pool is the vertex, which is contained in the standard form of the parabola. That is:
[tex]y-k = C\cdot (x-h)^{2}[/tex] (1)
Where:
[tex]x[/tex] - Independent variable, dimensionless.
[tex]y[/tex] - Dependent variable, dimensionless.
[tex]h[/tex], [tex]k[/tex] - Coordinates of the vertex, dimensionless.
[tex]C[/tex] - Constant, dimensionless.
The parabola is represented by [tex]f(x) = x^{2}+8\cdot x[/tex] and we proceed to transform into the desired form:
1) [tex]f(x) = x^{2}+8\cdot x[/tex] Given.
2) [tex]f(x) = (x^{2}+8\cdot x + 16)-16[/tex] Modulative property/Existence of the additive inverse.
3) [tex]f(x) +16 = (x+4)^{2}[/tex] Compatibility with the addition/Modulative property/Existence of the additive inverse/Perfect square trinomial.
4) [tex]y + 16 = (x+4)^{2}[/tex] Notation/Result.
Hence, the point that represents the bottom of the pool is [tex](x,y) = (-4, -16)[/tex].

what is the measure of arc qr?
26
52
104
128
Answer:
104°
Step-by-step explanation:
The principle to apply here is that angle subtended at the center of a circle is twice the angle at circumference.
Angle subtended at arc = 52°
Angle at the center = 2 x 52° = 104°
Answer:
104°

The picture is my question ( 2 math/algebra questions)
Answer:
question 1. (20)X = 100
question 2. the last one
Step-by-step explanation:
Answer:
Step-by-step explanation:
1. 20 a yard and made 100. 100/20=5 yards
20x=100
2. Since they don't give the number of yards they did mow, this would be my answer. I would say half the amount. Since they cut their rates in half, they'll have to cut twice as many to even the amount as before. They would have to cut three - four times as many to make over the original amount. They only have one weekend, so that'll be hard.

A map has a scale of 1 cm: 5 km. Determine how far apart two cities are if they are 8 cm apart on the map.
Answer:
i believe the answer is 40km.
Answer:
We are given that 1 cm on the map represents 5 km on earth's surface.
Then, if the cities are 8 cm apart on the map, they will be 8*5 = 40 km apart on Earth.

I think A and C if i'm correct
Step-by-step explanation:
Patrice and her family went to the movies. The data table below represents the amount of money they spend in dollars, f(x), in terms of the number of tickets, x,
they buy.
PART A
Write a linear function, f(x), that represents the data
PART B
Explain what the slope and y-intercept of f(x) mean in the given context.
Answer:
f(x) = 7.75x + 12.5
The slope represents the cost per movie ticket.
The intercept represents the flat fee paid to see movies.
Step-by-step explanation:
From the data given :
When x = 3 ; f(x) = 35.75
When x = 5 ; f(x) = 51. 25
Linear function :
y = mx + c
f(x) = mx + c
m = slope ; c = intercept
35.75 = 3m + c - - - (1)
51.25 = 5m + c - - - (2)
Subtract
-15.5 = - 2m
m = 15.5 / 2
m = 7.75
From (1)
35.75 = 3m + c
35.75 = 3(7.75) + c
35.75 = 23.25 + c
c = 35.75 - 23.25
c = 12.5
y = 7.75x + 12.5
f(x) = 7.75x + 12.5
B.) The slope represents the cost per movie ticket.
The intercept represents the flat fee paid to see movies.
