The given function in slope-intercept should be used to complete the table of values as follows;
x y
9 4
6 2
0 -2
-3 -4
A function that relates the distance (d) traveled to the time (t) is d = 120t.
A graph of the function is shown in the image attached below and it is a linear function.
How to complete the table of values?Mathematically, the slope-intercept form of a line can be calculated by using this equation:
y = mx + c
Where:
m represents the slope.x and y are the points.c represents the y-intercept.Next, we would use the given function in slope-intercept to complete the table of values as follows;
When y = 9, the value of x is given by:
y = 3x/2 + 3
9 = 3x/2 + 3
3x/2 = 9 - 3
3x/2 = 6
3x = 12
x = 12/3
x = 4.
When y = 6, the value of x is given by:
y = 3x/2 + 3
6 = 3x/2 + 3
3x/2 = 6 - 3
3x/2 = 3
3x = 6
x = 6/3
x = 2.
When y = 0, the value of x is given by:
y = 3x/2 + 3
0 = 3x/2 + 3
3x/2 = -3
3x = -6
x = -6/3
x = -2.
When y = -3, the value of x is given by:
y = 3x/2 + 3
-3 = 3x/2 + 3
3x/2 = -3 - 3
3x/2 = -6
3x = -12
x = -12/3
x = -4.
How to write a function for the distance and time?Mathematically, a constant of proportionality (speed) for this train's journey (distance) can be represented with the following mathematical expression:
d = kt
Where:
d represents the distance.t represents the time.k represents the constant of proportionality (speed).Next, we would determine the constant of proportionality (k) as follows:
Constant of proportionality (k) = d/t
Constant of proportionality (k) = 360/3
Constant of proportionality (k) = 120
Therefore, the required function that relates the distance (d) and time (t) is given by;
d = kt
d = 120t

Answer:
P(X > 2.6) = 0.0475 = 4.75%
Step-by-step explanation:
Let X is the random variable that represents percent of childhood asthma prevalence.
We want to find out the probability that the mean childhood asthma prevalence for the sample is greater than 2.6%
The z-score corresponding to 1.67 is 0.9525
P(X > 2.6) = 1 - 0.9525
P(X > 2.6) = 0.0475
P(X > 2.6) = 4.75%
Therefore, there is 4.75% probability that the mean childhood asthma prevalence for the sample is greater than 2.6%
How to use z-table?
Step 1:
In the z-table, find the two-digit number on the left side corresponding to your z-score. (e.g 1.6)
Step 2:
Then look up at the top of z-table to find the remaining decimal point in the range of 0.00 to 0.09. (e.g. if you are looking for 1.67 then go for 0.07 column)
Step 3:
Finally, find the corresponding probability from the z-table at the intersection of step 1 and step 2.

If an arrow is shot straight upward on the surface of the moon with initial velocity 60m/s, its height after t seconds is given by h(t) = 60t - 0.8t². (a) What is the velocity of the arrow after 1 second? (b) At what time t > 0 will the arrow hit the moon? (c) What is the velocity of the arrow when it hits the moon? (d) At what time does the arrow reach its maximal height? Show your working out!
The motion of the arrow, described by the kinematic equation for the height, h(t) = 60·t - 0.8·t² are as follows;
(a) The velocity after 1 second is 58.4 m/s
(b) The arrow hits the moon after 75 seconds
(c) The velocity of the arrow when it hits the moon is 60 m/s
(d) The arrow reaches the maximum height in37.5 seconds.
What is a kinematic equation?A kinematic equation is an equation that describes the motion of an object moving under constant acceleration.
The kinematic (equation) function for the height of the arrow is; h(t) = 60·t - 0.8·t²
The initial velocity of the arrow = 60 m/s
(a) The velocity of the arrow = The rate of change of the height, therefore;
v = h'(t) = 60 - 2 × 0.8·t = 60 - 1.6·t
The velocity after 1 second = h'(1) = 60 - 1.6 × 1 = 58.4
The velocity of the arrow after 1 second is 58.4 m/s
(b) When the arrow hits the moon, we get;
h(t) = 0, therefore;
h(t) = 60·t - 0.8·t² = 0
( 60 - 0.8·t)·t = 0
t = 0 or 60 - 0.8·t = 0
t = 60/0.8 = 75
The time the arrow hit the moon is 75 seconds after being shot
(c) The velocity of the arrow when it hits the moon is found using the equation;
h'(37.5) = 1.6 × 37.5 = 60
The velocity when it hits the moon, the velocity is 60 m/s
(d) The motion of the arrow is symmetrical, therefore, the time it takes the arrow to reach the the maximal height is the time it takes the arrow to reach back to the moon surface, which indicates;
The time it takes the arrow to reach maximum height is half the time it takes the arrow to hit the moon after being shot = 75/2 seconds = 37.5 seconds

The expression that shows how many comic books Tessa has is 14t
How to determine the expression?From the question, we have the following parameters that can be used in our computation:
Tessa = t times as many as Joseph
Joseph = 14 comic books
These parameters means that
Tessa = t times Joseph
So, we have
Tessa = t * Joseph
Substitute the known values in the above equation, so, we have the following representation
Tessa = t * 14

An orchard has 468 pear trees. The number of rows exceeds the number of trees per row by 8. How many trees are there in each row
If an orchard has 468 pear trees and The number of rows exceeds the number of trees per row by 8. the number of trees that are in each row would be 18
How to solve for the number of treesWe have to define T as the number of trees that are in a row.
Then we have to define t + 8 as the number of rows that we have
This would give us the equation that is written as
t(t + 8) = 468
then we would have
t² + 8t -468 = 0
We would have to find the factors of 468 which when inputted in the equation would give us the value 468
t(t + 8) = 468
This factor would be 18
such that
18 ( 18 + 8) = 468
18 * 26 = 468
468 = 468
Hence the number of trees that are in each row would be 18

The value of angle RPQ in the circle is 115 degrees.
How to find the angle in the circle?The intersecting chords theorem, also known as the chord theorem, is an elementary geometry statement that describes a relationship between the four line segments formed by two intersecting chords within a circle.
If two chords intersect inside a circle, then the measure of the angle formed is one-half the sum of the measure of the arcs intercepted by the angle and its vertical angle.
Therefore,
∠RPQ = 1 / 2 (arc angle RQ + arc angle SA)
arc angle RQ = 175 degrees
arc angle SA = 55 degrees
Hence,
∠RPQ = 1 / 2 (175 + 55)
∠RPQ = 1 / 2 (230)
∠RPQ = 115 degrees.
