Which of the following polynomial functions is graphed below?
Answer: B. f(x)=(x+4)(x-2)^2(x+3)
Step-by-step explanation:
in the graph there's two negative x value and one positive x value
so the function should be in a form of f(x)= (x+a) (x-b)^2 (x+c)
the one with negative value has a square, (x-b)^{2}, because that's where the y = 0 (the point is hitting the (x,0))

Answer:
-30
-Step-by-step explanation:
Step 1: Simplify both sides of the equation.
1/2y+5=-10
Step 2: Subtract 5 from both sides.
1/2y+5-5=-10-5

A student cycles a distance of 63 km in less
than 3 hours. What is the average speed?
Answer:
About About 21 km/h
Step-by-step explanation: If they travel 63 km in 3 hours then all it is is just 63 divided by 3 or 63/3.
The average speed for the cycle will be 21 km per hour.
What is an average speed?Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance traveled by time. The unit of speed in miles per hour.
The average speed is defined as the ratio of the total distance traveled and the total time taken by the object.
Given that A student cycles a distance of 63 km in less than 3 hours. The average speed is calculated as:-
Average speed = Distance / time
Average speed = 63 / 3
Average speed = 21 km / hr

Identify the property on this equation 5(a + 3b) = 5a + 15b
Answer:
??????????????????????
Step-by-step explanation:
Answer: Distributive Property
The term "distribution" is also used in place of "distributive"
This property says
x*(y+z) = x*y + x*z
We multiply the outer term x with each inner term (y and z). Then we add the results.
In this case,
x = 5
y = a
z = 3b
So,
5(a+3b) = 5*a + 5*3b = 5a+15b

Find the area of this parallelogram.
5 cm height
7 cm width
Answer:
35 cm^2
Step-by-step explanation:
To find the area you need to find the width and height which we have.
Now all you need to do is to use the formula Height x Width= area
so replace height with 5 cm and width with 7 cm
5 cm x 7 cm = area
5 times 7 is 35 so the area of the parallelogram is 35 cm^2 (cm times cm is cm^2)
Hope this helps!
Answer:

How far from the door must a ramp begin in order to rise 3 feet with an 8 degree angle of elevation
Answer:
Step-by-step explanation:
We know that the angle of elevation is 8 degrees.
We know that the height of the opposite side of the angle is 3 feet.
We want to know the adjacent side (the side from the start of the ramp to the bottom of the opposite side)
We can do this with tangent
[tex]tan(8) = \frac{3}{adj} \\adj = \frac{3}{tan(8)} \\adj = 21.34611 feet[/tex]
The distance between the ramp and the door can be calculated using the principle of Pythagoras, Hence, the distance should be 21.34 feets
Angle of elevation = 8°Rise = opposite = 3 feets Distance, d = adjacentUsing SOHCAHTOA :
Tanθ = Opposite / Adjacent
Tan(8°) = 3 / d
0.1405408 = 3 / d
0.1405408d = 3
Divide both sides by 0.1405408 to isolate d
0.1405408d / 0.1405408 = 3 / 0.1405408
d = 21.34 feets
Therefore, the distance of the ramp from the door should be 21.34 feets

A population of values has a normal distribution with μ=152.8 and σ=26.2 . You intend to draw a random sample of size n=94 . Find the probability that a single randomly selected value is less than 149.6. P(X < 149.6) =
Answer:
P(x < 149.6) = 0.11821
Step-by-step explanation:
We start by calculating the z-score of the parameter given
Mathematically,
z-score = (x-mean)/SD/√n
z-score = (149.6-152.8)/26.2/√94
z-score = -3.2/2.70
z-score = -1.18
So the probability we want to calculate is;
P( x < -1.18)
we can use the standard normal distribution table to get this
From the standard normal distribution table, this value is 0.11821

The last one 5x-3y=15 This is the same as y= (5/3)x -5
Step-by-step explanation:
5x-3y=15
Move 5x to the right (becoming negative)
-3y = -5x +15
Divide everything by - 3
y= (5/3)x -5
y intersect= -5 ( line crosses y coordinate at -5)

You are baking a cake, and the recipe calls for 3/8 of a cup of flour and 1/2 of a cup of sugar. What is the total amount of flour and sugar, as a reduced fraction?
Answer:
[tex]\frac{7}{8}[/tex]
Step-by-step explanation:
To find the total amount of flour and sugar, you have to find a common denominator for the two fractions and then add them together.
[tex]\frac{1}{2}[/tex] multiplied by 4 equals [tex]\frac{4}{8}[/tex].
Now that the fractions both have a common denominator of 8, we can add them together:
[tex]\frac{3}{8}[/tex] + [tex]\frac{4}{8}[/tex] = [tex]\frac{7}{8}[/tex]
The total amount of flour and sugar is [tex]\frac{7}{8}[/tex]
