What is an equation of the line that passes through the points (8,0) and (3,-5)?
Answer:
y = x - 8
Step-by-step explanation:
You want an equation for the line through the points (8, 0) and (3, -5).
SlopeThe slope of the line can be found using the formula ...
m = (y2 -y1)/(x2 -x1)
m = (-5 -0)/(3 -8) = -5/-5 = 1
InterceptThe y-intercept can be found from the equation ...
b = y1 -m(x1)
b = 0 -1(8) = -8
Slope-intercept equationThe slope-intercept equation of the line is ...
y = mx +b
y = 1·x +(-8)
y = x -8 . . . . . an equation for the line

1. Two containers are being filled with water. One begins with 10 gallons of water and is filled at a rate of 2.5 gallons per minute. The other begins with 24 gallons and is filed at 2.25 gallons per
minute.
Part A: Write an equation that represents the amount of water w, in gallons, with respect to time t, in minutes, for each container
Part B: Solve the system of equations. Show your work
Part C: How long would it take for both of the containers to have the same amount of water? How much water would be in each container?
Answer: PART A:
w-3.5 t=8
w-3.25t=24
PART B:
t=64
and w= 232
PART C:
It will take 64 minutes for both of the containers to have the same amount of water.
The amount of water in each container is:
232 gallons.
Step-by-step explanation:
PART A:
Let the water is filling in 't' minutes.
and 'w' denotes the amount of water in the container.
for container 1:
One begins with 8 gallons of water and is filled at a rate of 3.5 gallons per minute.
The equation is given by:
or
for container 2:
The other begins with 24 gallons and is filled at 3.25 gallons per minute.
The equation is given by:
or
PART B:
on solving equation (1) and equation (2) by method of elimination we get:
subtract equation (2) by equation (1) to obtain:
t=64
and putting the value of t in equation (1) to obtain:
w= 232
PART C:
Hence it will take 64 minutes for both of the containers to have the same amount of water.
The amount of water in each container is:
232 gallons.

Answer:
[tex] \sf \: -n + 1 [/tex]
Step-by-step explanation:
Given information,
→ h(n) = n + 2
→ g(n) = 2n + 1
Now we have to,
→ find the value of h(n) - g(n).
Then required value will be,
→ h(n) - g(n)
→ (n + 2) - (2n + 1)
→ n + 2 - 2n - 1
→ (n - 2n) + (2 - 1)
→ (-n) + (1)
→ -n + 1
Hence, the value is -n + 1.

Which ratio best defines relative frequency? Number of nonfavorable outcomes:Number of possible outcomes Number of possible outcomes:Number of nonfavorable outcomes Total number of times an experiment is performed:Number of times an event occurs Number of times an event occurs:Total number of times an experiment is performed.
The ratio which best defines relative frequency is, number of times an event occurs:Total number of times an experiment is performed.
What is relative frequency?Relative frequency of a event is the measure of something happens relative to the total outcomes of that event.
The relative frequency can be given as,
[tex]f_r=\dfrac{f}{n}[/tex]
Here, (f) is the frequency of the number of times data occurred in an event and (n) is the total number of outcomes.
The relative frequency can also be defined as, it is the ratio of subgroup frequency to the total frequency of any event.
Now, the ratio has to be find out which best defines relative frequency. Lets check options,
Number of non-favorable outcomes:Number of possible outcomes-Here, the non-favorable outcomes is asked but for the relative frequency the favorable outcomes is considered. Number of possible outcomes:Number of non-favorable outcomes-The number of total outcomes is considered for a relative frequency. Total number of times an experiment is performed:Number of times an event occurs-This ratio is inverse as the ratio of relative frequency.Number of times an event occurs:Total number of times an experiment is performed-This is the correct option, as it justify the definition of the relative frequency.Hence, the ratio which best defines relative frequency is, number of times an event occurs:Total number of times an experiment is performed.

a cone has a volume of 150.72 cubic millimeters and a height of 9 millimeters what is the radius
The volume of a cone is the amount of space in the cone
The radius of the cone is 4.00 millimeters
How to determine the radiusThe given parameters are:
Volume = 150.72 cubic mL
Height = 9 mL
The volume of a cone is calculated as:
[tex]V = \frac 13 \pi r^2h[/tex]
So, we have:
[tex]150.72 = \frac 13 \pi * r^2 * 9[/tex]
Divide
[tex]150.72 = \pi * r^2 * 3[/tex]
Divide both sides by 3
[tex]50.24 = \pi * r^2[/tex]
Rewrite the equation
[tex]50.24 = \frac{22}{7} * r^2[/tex]
Solve for r^2
[tex]r^2 = 50.24 * \frac{7}{22}[/tex]
Solve for r
[tex]r = 4.00[/tex]
Hence, the radius of the cone is 4.00 millimeters

When a polynomial P(x) is divided by (x-t) then the remainder of the division is equal to P(t). If P(t)=0, then the (x-t) is the factor of the polynomial. The factors of x³-5x+6 are (x+5)(x-2)(x-3).
What is the Remainder theorem?According to the remainder theorem, when a polynomial P(x) is divided by (x-t) then the remainder of the division is equal to P(t). If P(t)=0, then the (x-t) is the factor of the polynomial.
Since f(–5) = 0, therefore, (x+5) is a factor of the polynomial f(x).
