Select the correct answer from each drop-down menu. use . a boy weighing kilograms is riding a skateboard. he’s moving at 2 meters/second and has 40 joules of kinetic energy. he doubles his speed when he sees his friends ahead of him. his kinetic energy at the faster speed is joules.
Answers
If he doubles his speed when he sees his friends ahead of him. his kinetic energy at the faster speed is joules is 160Joules
Kinetic energy of an object.The formula for calculating the kinetic energy of an object is expressed as:
KE = 1/2mv²
where:
m is the mass of an object
v is the velocity
If he’s moving at 2 meters/second and has 40 joules of kinetic energy, the mass is calculated as:
40 = 0.5(2)²m
40 = 2m
m = 20 kg
If he doubles his speed when he sees his friends ahead of him, his kinetic energy will be:
KE = 0.5(20)(4)²
KE = 10*16
KE = 160joules
Hence if he doubles his speed when he sees his friends ahead of him. his kinetic energy at the faster speed is joules is 160Joules

Identify the growth factor for the following exponential function: y= 2.3(1.32)*
A. 2.3
B. 1.32
C. X
D. 32%
Answers
Answer:
D. 32%
Step-by-step explanation:
In an exponential function, exponential growth is modeled by f(x) = a(1 + [rate])ˣ. In this function, the initial value a, which is 2.3, is multiplied by 1.32 x times, so 1.32 represents the actual growth happening.
This means that to find the actual rate of exponential growth, you’d have to set 1.32 equal to (1 + [rate]). If (1 + [rate]) = 1.32, then the rate = .32, and because rates are written as percentages, we change .32 to 32%.

At the circus, an acrobat is standing on a platform that is 27 feet from the ground when he sees a peanut on the ground below. How far is the peanut away from the base of the platform if the angle of elevation from the peanut to top of the acrobat's platform is 25°?
Answers
Answer:
The peanut is 12.59 feet away from the base of the platform.
Step-by-step explanation:
When solving these equations, we can first start out by noticing that this requires a trigonometry function.
There are three types : cos, sin, and tan. (cosine, sin, and tangent)
Cos is for finding and dealing with the adjacent and the hypotenuse.
Sin is for finding and dealing with the opposite and the hypotenuse.
Tan is for finding and dealing with the opposite and the adjacent.
The opposite is the bottom base, to the peanut.
The adjacent is the height from the bottom base, to the top.
The hypotenuse is the top, to the peanut.
27 feet would be the adjacent.
Since we don't know bottom base to the peanut, we would call this x. (opposite)
*Side note* : The degrees is always in between the adjacent and hypotenuse.
For this, we need the length between the peanut and the bottom base. This would be the adjacent and the opposite. Meaning we're using tangent. The equation for tangent is :
tan (degrees) = opposite/adjacent
So, now we simply put in the data.
tan 25 = x/27
We can now, first get x alone by multipling both sides by 27.
27 * tan 25 = x
Plug this into a scientific calculator :
27 * tan 25
We the answer to be 12.59

Jacob earned a gross pay for the week of $592. If 16% was withheld for deductions, what was his net pay?
Answers
Answer:
$497.28
Step-by-step explanation:
First, you need to find 16% of 592. To do this, turn 16% into a decimal by dividing by 100:
16/100 = 0.16
Then, multiply 0.16 by 592, to get 94.72.
Then, subtract this number from 592:
592 - 94.72 = 497.28

Answer:
tanΘ = [tex]\frac{4}{3}[/tex]
Step-by-step explanation:
tanΘ = [tex]\frac{opposite}{adjacent}[/tex]
the opposite side requires to be found.
let the opposite side be x then using Pythagoras' identity in the right triangle
x² + 12² = 20²
x² + 144 = 400 ( subtract 144 from both sides )
x² = 256 ( take square root of both sides )
x = [tex]\sqrt{256}[/tex] = 16

tanΘ = [tex]\frac{16}{12}[/tex] = [tex]\frac{4}{3}[/tex]
5. For the past 10 days, a city planner has counted the number of
northbound cars that pass through a particular intersection During
that time, 200 or more cars were counted 9 out of 10 days.
a. What is the experimental probability that there will be 200 or more
northbound cars passing through the intersection on the eleventh day?
b. What is the experimental probability that there will not be 200 or
more northbound cars passing through the intersection on the
eleventh day?
Can someone please help I’m stuck ( and please show the work) thank you.
Answers
The number of cars was counted on 10 days and thus there were 10 trials.
# of trials=10
200 or more cars were counted on 9 of the 10 days and thus the event occurs 9 times.
# of times the event occurs= 9
The probability is the number of times the event occurs divided by the number of trials:
P ( 200 or more cars)= # of times the event occurs / # of trials
=9/10
0.9
90%
We know that the sum Of the probabilities Of an event And it’s Complement needs to be equal to 1.
P( event ) + P ( complement)= 1
What is it is “200 or more cars”
P( 200 or more cars) + P (not 200 or more cars) = 1
Since P ( 200 or more cars) = 9/10 we can replace P ( 200 or more cars) in the equation by 9/10
9/10 +P ( not 200 or more cars) =1
Subtract 9/10 from each side
-9/10= 1-9/10
Combine like terms
P( not 200 or more cars) = 1/10= 0.1 = 10%
A: 9/10 = 0.9 = 90%
B: 1/10= 0.1= 10%
