Answer:
m=4/3
b=0
Step-by-step explanation:
m= is the slope, which is 4/3 and b is the y intercept, which is (0,0). The equation would be y=4/3x+0 but we do not have to include the 0 making it y=4/3x. The equation is proportional becuase it goes through the point (0,0) and it is linear as it is a linear line.
by what percent will a fraction change if its numerator is decreased by 75% and denominator is decreased by 50%
Answer:
50%
Step-by-step explanation:
first the numerator is decreased by 75% so its 0.25. the denominator is decreased by 50% so its 0.5. Then, we will divide 0.25 and 0.5 which equals 0.5. to find %, do 0.5*100 which equals 50%
The fraction will decrease by 0.5 or 50%
Let the original fraction be a/b. If the numerator is decreased by 75% and the denominator is decreased by 50%, the resulting faction will be:
0.25a/0.50b
Taking the ratio of the quotient of the result will give:
0.25a/0.50b
= 25/100a * 100/50 b
= 25a/50b
= 0.5a/b
Hence the fraction will decrease by 0.5 or 50%

The equation y = 12 - 0.2x shows the amount of candle that is left (in ounces) after
burning for x hours. What is the y - intercept for the function, and what does it represent
Answer:
The y-intercept is 12.
It represents the original length of the candle.
Step-by-step explanation:
y = 12 - 0.2x
y = 0.2x + 12
y = mx + b
b is the y-intercept.
b = 12
The y-intercept is 12.
It represents the original length of the candle.

The diagram shows the number of quarts of blood the human heart pumps per minute. A drawing shows an anatomy of human heart. Label reads: Pumps 5 quarts of blood per minute. a. How many quarts of blood does the human heart pump per hour? quarts per hour Question 2 b. How many liters of blood does the human heart pump per minute? liters per minute
The unitary method is used to find the unit value of any quantity.
(a)The human heart pumps 300 quarts/hour.
(b) The human heart pumps 4.730 liters/minute.
What is Unitary method ?In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.
Given that,
Reading on the label is 5quarts/min.
Since, 60 min = 1 hour
Use unitary method to get,
1 min = 1 / 60 hour.
Therefore, pumping of blood in quarts/hour = 5 / (1 / 60)
= 5 × 60
= 300
Since, 1 quart = 0.946 liter
The pumping of blood in liter/minute = 0.946 × 5
= 4.730.
Hence, the human heart pumps 300 quarts of blood per hour and 4.730 liter of blood per minute.

What is a decimal number?A decimal number is a number that consists of a whole number and a fractional part separated by a point. For example – 3.5, 6.79, 78.32, etc.
Given here: Given the proper fraction as 1/4
To convert a fraction to a decimal, we'll just divide the numerator...by the denominator.
Thus 1/4=0.25
1/2=0.5
Now the difference between each of the given points is 1/2-1/4=0.25
And 1/4-0=0.25
Also 1-1/4=0.75
Thus the point 1/4 is equidistant from the points 0 and 1/2 but is 0.75 units away from 1

during a test of a totalizing flow meter, the water depth rose 15 inches in a tank 18 inches in diameter. What was the total flow in gallons
Answer:
The total flow in gallons is approximately 16.524 gallons
Step-by-step explanation:
The given diameter of the tank, D = 18 inches
The amount by which the water depth rose, Δh = 15 inches
The quantity being measured = The total flow = The change in volume of water in the tank
The change in the volume of the water in the tank, ΔV = (π × D²/4) × Δh
Substituting the known values, gives;
ΔV = (π × D²/4) × Δh = (π × (18 in.)²/4) × (15 in.) ≈ 3817.035 in.³
1 gallon = 231 in.³
ΔV ≈ 3817.035 in.³ = 3817.035 in.³ × 1 gallon/(231 in.³) ≈ 16.524 gallons
The change in the volume of the water in the tank, ΔV in gallons = The total flow in gallons ≈ 16.524 gallons.

The graph of absolute value function f(x) and g(x) are:
On a coordinate plane, y = g (x) opens up and goes through (6, 4), has a vertex at (7, 0) and goes through (8, 4). Y = f (x) opens up and goes through (negative 4, 4), has a vertex at (0, 0), and goes through (4, 4).
The correct answer is an option (B)
What is an absolute value function?"A function of the form f(t) = |t| ."
What is a graph of a function?"It is a set of points on the coordinate plane that follows given function."
For given question,
We have been given an absolute value function f(x) = |x|
and absolute value function g(x) = |-4(x - 7)|
The graph of f(x) = |x| is like a 'V', with its vertex at (0, 0).
Y = f (x) opens up and goes through (-4, 4), has a vertex at (0, 0), and goes through (4, 4)
Consider absolute value function, h(x) = |x - 7|
A function h(x) is the function f(x) is translated horizontally 7 units right.
The graph of h(x) = |x - 7| is like a 'V', with its vertex at (7, 0).
Now consider absolute value function g(x) = |-4(x - 7)|
A function g(x) is the function h(x) is compressed inside by factor 4.
So, the graph of y = g (x) opens up and goes through (6, 4), has a vertex at (7, 0) and goes through (8, 4).
Therefore, the graph of absolute value function f(x) and g(x) are:
On a coordinate plane, y = g (x) opens up and goes through (6, 4), has a vertex at (7, 0) and goes through (8, 4). Y = f (x) opens up and goes through (negative 4, 4), has a vertex at (0, 0), and goes through (4, 4).

A particle moves along the curve y = 5x^2 – 1 in such a way that the y value is decreasing at the rate of 2 units per second. At what rate is x changing when x = 1?
Decreasing one fifth unit/sec
Increasing one fifth unit/sec
Decreasing one tenth unit/sec
Increasing one tenth unit/sec
Answer:
The correct option is;
Increasing one fifth unit/sec
Step-by-step explanation:
The equation that gives the curve of the particle of the particle is y = 5·x² - 1
The rate of decrease of the y value dy/dt = 2 units per second
We have;
dy/dx = dy/dt × dt/dx
dy/dx = 10·x
dy/dt = 2 units/sec
dt/dx = (dy/dx)/(dy/dt)
dx/dt = dy/dt/(dy/dx) = 2 unit/sec/(10·x)
When x = 1
dx/dt = 2/(10·x) = 2 unit/sec/(10 × 1) = 1/5 unit/sec
dx/dt = 1/5 unit/sec
Therefore, x is increasing one fifth unit/sec.
