Which function is represented by the graph?
Answer:
square root function; y = -√(x + 2) - 1
Step-by-step explanation:
the graph shown is a square root function
the parent of a square root function is y = √x
you transform this equation using y = a√(x - h) + k
it is reflected across the x axis so you put the negative before the a
since there is no dilation the a is blank
y = -√(x - h) + k
the h is the horizontal shift
it went 2 to the left so that is -2
that makes it y = -√(x - -2) + k
which is also y = -√(x + 2) + k
the k is the vertical shift
it went 1 down
that makes it y = -√(x + 2) - 1
that is your equation

You are riding the bus to school and you realize it is taking longer because of all the stops you are making. The time it takes to get to school, measured in minutes, is modeled using the function gox)=x²-3x²
number of stops the bus makes if the bus makes 2 stops after you board, how long does it take you to get to school?
01 minute
03 minutes
07 minutes
O11 minutes
4x-5, where x is the
F
The time taken for the person to get to school based on the equation will be 7 minutes.
How to calculate the time?From the information given, the equation is given as:
g(x) = x⁴ - 3x² + 4x - 5
Then, we'll put 2 as x. This will be:
= 2⁴ + 3(2)² + 4(2) - 5
= 16 - 12 + 8 - 5
= 7
Therefore, the time taken for the person to get to school based on the equation will be 7 minutes.

Answer:
Step-by-step explanation:

x^2 + 1936 = 3025
3025-1936 = 1089
sqrt(1089) = 33

What are the y-intercept and the asymptote of g(x) = 2x – 3?
The y-intercept of g(x) is (0, -3) and there are no asymptotes for g(x).
The function is given as g(x) = 2x - 3 and we need to find the y-intercept and the asymptote of this function g(x).
What are the y-intercept and asymptotes of a given function?Y-intercepts of a given function are the points on the y-axis that the given function passes through.
In y-intercept points we always have x=0.
Asymptotes are straight lines on the graph that meets the given function as it moves towards infinity.
Asymptotes occur only when the given function is a rational function or when one term of the function approaches zero as one term approaches infinity.
Find the y-intercept of g(x).
We have,
g(x) = 2x - 3
Since x = 0.
we get,
g(x) = 0 - 3
g(x) = -3 or y = -3
Thus the y-intercept of g(x) is (0, -3)
Find the asymptotes of g(x).
We see that g(x) is not a rational function and when x approaches infinity g(x) does not approach zero.
Hence we can say that g(x) has no asymptotes.
The y-intercept and asymptotes of g(x) are (0, -3) and no asymptotes.

Determine the vertex form of g(x) = x^2 + 2x – 1. Which graph represents g(x)?
Answer:
Graph D
Step-by-step explanation:
Move the constant to the opposite side of the equation and group terms that include the same variable.
g(x) + 1 = x^2 + 2x
Finish the square. Remember to keep the equation balanced by using the same constants on both sides.
g(x) + 1 + 1 = x^2 + 2x + 1
g(x) + 2 = x^2 + 2x + 1
Rewrite as perfect squares
g(x) + 2 = (x + 1)^2
Equation in vertex form:
g(x) = (x + 1)^2 - 2

Four students were discussing how to find the unit rate for a proportional relationship. Which method is valid? “Look at the graph of the relationship. Find the y-value of the point that corresponds to x = 1. That value is the unit rate.” “Look at the graph of the relationship. Count the number of units up and the number of units to the right one must move to arrive at the next point on the graph. Write these two numbers as a fraction.” “Look at the graph of the relationship. Find the x-value of the point that corresponds to y = 2. That value is the unit rate.” “Look at the graph of the relationship. Find two points which have y-values that are one unit apart. The unit rate is the difference in the corresponding x-values.”

Find the surface area of the shape below. Round your answer to two decimal places.
The surface area of the given shape is 285.01 ft²
Surface area of a coneFrom the question, we are to calculate the surface area of the given shape.
The given shape in the diagram is a cone.
The surface area of a cone is given by the formula,
[tex]S = \pi r(r+l)[/tex]
Where S is the surface area
r is the radius
and [tex]l[/tex] is the slant height
First, we will calculate the slant height of the cone
[tex]l^{2}=9^{2} +5.6^{2}[/tex] (Pythagorean theorem)
[tex]l^{2}=81+31.36[/tex]
[tex]l^{2}=112.36[/tex]
[tex]l}=\sqrt{112.36}[/tex]
[tex]l=10.6 \ ft[/tex]
∴ The slant height is 10.6 ft
Now, for the surface area
[tex]S = \pi \times 5.6(5.6+10.6)[/tex]
[tex]S = \pi \times 5.6(16.2)[/tex]
[tex]S = 90.72\pi \ ft^{2}[/tex]

After 15 seconds rocket reaches to maximum height is 225 units.
What is Differentiation?Differentiation means the rate of change of one quantity with respect to another. The speed is calculated as the rate of change of distance with respect to time.
Here, the given equation of height
h(t) = -t² + 30t
y = -t² + 30t
Now, on differentiating both side with respect to t, we get
dy/dt = -2t + 30
put dy/dt = 0, we get
0 = -2t + 30
2t = 30
t = 15
Now, at t = 15 sec. rocket reach at its maximum height.
maximum height at t = 15 sec is
h(15) = -(15)² + 30(15)
h(15) = -225 + 450
