Using translation concepts, the transformations are given as follows:
a) The function is horizontally compressed by a factor of 3 and shifted down one unit.
b) The function is shifted right 3 units and vertically stretched by a factor of 2.
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
Item a:
The transformations are:
x -> 3x, hence the function is horizontally compressed by a factor of 3.y -> y - 1, hence the function is shifted down one unit.Item b:
The transformations are:
x -> x - 3, hence the function is shifted right 3 units.y -> 2y, hence the function is vertically stretched by a factor of 2.More can be learned about translation concepts at https://brainly.com/question/4521517

Jin has $0.20 worth of pennies and nickels. He has a total of 12 pennies and nickels altogether. By following the steps below, determine the number of pennies, x, and the number of nickels, y that Jin has.
The number of pennies, x, and the number of nickels, y that Jin has is 10 and 2 respectively.
Pennies and nickelsA penny = $0.01A nickel = $0.05number of pennies = xNumber of nickels = yThe equation:
x + y = 12
0.01x + 0.05y = 0.20
from (1)
x = 12 - y
substitute 12-y into (2)
0.01x + 0.05y = 0.20
0.01(12 - y) + 0.05y = 0.20
0.12 - 0.01y + 0.05y = 0.20
- 0.01y + 0.05y = 0.20 - 0.12
0.04y = 0.08
y = 0.08/0.04
y = 2
substitute y = 2 into (1)
x + y = 12
x + 2 = 12
x = 12 - 2

What is the assessed valuation of a house with a $152,740 market value and a 60 percent assessment rate?
O $254,567
O $244,384
$91,644
O $61,096
Answer:
$254,567
Step-by-step explanation:
The houses market value is $152,740 and has a 60% assessment rate, the assessed valuation of this house would be $254,567. How we got this was by dividing the house total which is $152,740 by the assessment percentage rate which is 60 percent. Simply $152,740÷0.60

How many times will the lines intersect?
Step-by-step explanation:
here we have to know that, if A/B=A'/B' is equal to 1 it means it doesn't cut. if it isn't equal to 1, it does.
A=3 B=4
A'=4 B'=3
3/4=4/3 it cuts. Now, they are straight lines because we don't have x² or anything, so they can just intersect once between them.

The estimated probability that at least one of the next four fish Roxanne catches will be a perch is 34%
What is Probability ?Probability is the likeliness of an event to happen. It has a range of 0 to 1, where 0 indicates uncertainty and 1 indicates certainty.
It is given that
0, 1, and 2 represent trout , 3 and 4 represent bass , 5 represent perch , 6, 7, 8, and 9 represent other fish
From the data it can be observed that
Total number of single digits numbers = 80
No. of Perch , "5 " = 8
Probability of getting a perch in next fish = 8/80 = 0.1
Probability that at least one of the next four fish Roxanne catches will be a perch = 1- P(no perch)
P ( no perch) = 1 - 0.1 = 0.9
for 4 fishes
= 1 - 0.9⁴

Given An outlier is a data value that is numerically distant from_________ of the other data points in a set of data.
We have to fill the blank. We can fill " most" in the blank.
If a number in data is more than 1.5 times the length of the box away from either of the upper and lower quartile of the distribution then that number is said to be an outlier.
There are two types of outliers: upper outliers, lower.

Jaylen and ken started jogging from the same place in the opposite directions along a straight path. jaylen's speed was 30 m/min faster than ken's speed. both of them did not change their speeds throughout the jog. at the end of the jog, they were 13.6 km apart. jaylen jogged 2.4 km more than ken. what was ken's average speed?
The average speed of Ken is 70 m/min. Using the relation between the speed and distance, the required speed for Ken is calculated.
What is the relation between speed and distance?The relationship between speed S and distance D with a period T is formed as
S = D/T
Units: m/sec (basic unit)
Calculation:Given that,
Jaylen and Ken started jogging from the same place in opposite directions along a straight path.
This means, that the sum of distances traveled by both of them in opposite directions = 13.6 km (since it is given that at the end of their jogging, they are 13.6 km apart)
Consider,
The distance traveled by Jaylen = x km
Then the distance traveled by Ken = x - 2.4 km (since Jaylen jogged 2.4 km more than Ken)
Step 1: Finding the distance traveled by them:
x + x - 2.4 = 13.6
⇒ 2x = 13.6 + 2.4
⇒ 2x = 16
⇒ x = 8 km
So, the distance travelled by Jaylen = 8 km and by Ken = 8 - 2.4 = 5.6 km
Step 2: Finding the average speed traveled by Ken:
Since it is given that,
Jaylen's speed was 30 m/min faster than Ken's speed.
So,
For 30 m, the time = 1 min
then for 2.4 km i.e., 2400 m, the time = 80 min.
Therefore,
the average speed of Ken S = D/t
⇒ S = 5600 m / 80 min
∴ S = 70 m/min.
So, the average speed of Jaylen will be 70 m/min + 30 m/min = 100 m/min.
Thus, the average speed of Ken is 70 m/min.

What is the value of the discriminant of the quadratic equation-2x^2=-8x+8,and what does its value mean about the number of real number solution the equatioj has?
The value of the discriminant is zero and therefore the equation has two equal and real roots.
What is discriminant ?For a quadratic Equation ax²+bx+c = 0 , the discriminant is D = b²-4ac
The given quadratic equation is -2x² = -8x+8
comparing with the standard equation
a = 1
b = -4
c = 4
Simplifying the equation given
[tex]\rm -2x^2+8x-8 = 0\\\\ -2(x^2-4x+4) = 0\\\\x^2-4x+4 = 0[/tex]
The discriminant is given by
D = (-4)²-4 * 1 *4
