The height of the poster is 20 inches.
The original width of the poster was 6 inches. The original height of the poster was 4 inches. The size of the poster is scaled up. This is a transformation of the size of the poster. The width of the scaled-up poster is 30 inches. We need to find out the height of the scaled-up poster.
The scaling transformation preserves the shape of the object. This means the sides must still be in the same proportion. Let the constant of proportionality be represented by the variable "k".
30 = k*6
k = 30/6
k = 5
Hence, the poster is scaled up by a factor of five.
H = k*4
H = 5*4
H = 20
Hence, the height of the scaled-up poster is 20 inches.
The complete question is given below.

A 100-gallon fish tank fills at a rate of x gallons per minute. The tank has already been filling for 5 minutes. The
function f(x)=100/x-5 represents the remaining time in minutes needed to fill the tank. How is the graph of the parent function f(x)=1/x
transformed to create the graph of the function f(x)=100/x-5?
Answer:
The parent graph has been dilated by a scale factor of 100 and has been moved to the right by 5 units
Step-by-step explanation:
The change made to f(x) = 1/x to f(x) = 100/x is a dilation by a scale factor of 100(the function has been multiplied by 100) .
The transformation of function f(x) = 100/x to f(x) = 100/x-5 is moving o the right 5 units (whenever a constant, let's call it "c", is being subtracted from the x when graphing, it means the graph has moved "c" units to the right, and vice versa--if "c" was added to x, then the graph would be moved "c" units to the left.).
TL;DR: f(x-c) means c units to the right, f(x+c) means c units to the left. f(x)*c means a dilation of c units.

raina swam 8 kilometers against the current in the same amount of time it took her to swim kilometers with the current. the rate of the current was kilometer per hour. how fast would raina swim if there were no current?
The speed at which raina can swim if there is no current is 3 km/hor 3 kilometers per hour.
Given that,
In the same length of time it took raina to swim kilometers with the river, she was able to swim 8 kilometers against it. The current flowed at a kilometer per hour rate.
Distance 1 * (Raina's velocity - current velocity) = Distance2 * (Raina's velocity + current velocity)
16 * (Raina's velocity - 1) = 8 * (Ivan's velocity + 1)
(16 * Raina's velocity) - 16 = (8 * Ivan's velocity) +8
8 * Raina's velocity = 24
Raina's velocity = 3 kilometers per hour
As a result, Raina can swim at a speed of 3 km/hr in the absence of a current.

Which ordered pairs is a solution to 5x+3y>12 Question 2 options: (3, 9) (-5, 5) (3, -6) (-2, -5) (2, 8) (-6, 0)
The solution to the expression given as 5x + 3y > 12 has the ordered pair of (3, 0)
How to determine the ordered pair of the solution?From the question, we have the following inequality that can be used in our computation:
5x + 3y > 12
Solving further, we need to collect the like terms
So, the expression becomes
3y > 12 - 5x
Next, we divide through the inequality by 3
So, we have the following representation
y > 12/3 - 5/3x
Evaluate
The equation becomes
y > 4 - 5/3x
At this point, we assume any value for x and then solve for y
Assume that the value of x is 3
So, we have the following representation
y > 4 - 5/3 * 3
Evaluate the products
y > -1
A value greater than -1 is 0
So, we have
x = 3 and y = 0
Express as ordered pairs
(x, y) = (3, 0)
Hence, the ordered pair of the solution is (3, 0)

b. What might best explain the strong correlation (as a lurking variable)?
Select one:
_____ Percent of young people
____ General economic conditions of the country
____ Percent of pop. living in cities
Which answer is correct?
(A) y = 3x − 2
y = 2x + 5
(B) y = −3x + 2
y = 2x − 5
(C) y = −3x − 2
y = −2x − 5
(D)y = 3x + 2
y = −2x + 5
Step-by-step explanation:
the slow of a line is the factor of x in a "y = ..." firm of equation.
the line going through (1, 5) has a slope of 3 (when x increases by +1, then y increases by +3, so the slope y/x = 3).
(B) and (C) are out, because there is no line with slope 3 (only -3).
the line going through (-2, 9) has a slope of -2 (when x increases by 1, y decreases by 2, so the slope y/x = -2/1 = -2).
(A) is out, as there is no line with the slope -2 (only +2).
so, (D) is the correct answer.
