Note: Enter your answer and show all the steps that you use to solve this problem in the space provided. Solve 2s^3 - 4r^2 = if r = 1 and s = 5
The Value of the expression 2s³ - 4r² by substituting the given values into the expression is 246
Given the equation ; 2s³ - 4r²
Value of r = 1 ; value of s = 5To solve, substitute the values of r and s into the equation :
2(5)³ - 4(1)²
2(5 × 5 × 5) - 4(1 × 1)
2(125) - 4(1)
250 - 4
= 246
Therefore, the final value of the expression by substituting the value of r and s as 1 and 5 respectively is 246

A rectangular room is 11 feet by 18 feet. The ceilings are 10 feet high. If a gallon of paint covers 250 square feet. How many gallons of paint are needed to paint the room?
Answer:
2.32 gallons of paint
Step-by-step explanation:
First, find the area of all 4 sides of the room, with the equation A = lw
11(10)
= 110 (for 2 of the walls)
18(10)
= 180 (for the other 2 walls)
Add these up:
110 + 110 + 180 + 180
= 580
Then, divide this by 250:
580/250
= 2.32
So, 2.32 gallons of paint will be needed to paint the room.

Find the coordinate of the midpoint of GH with endpoints G(-5,4) and H (-5,8)
Answer:
(-5,6)
Step-by-step explanation:
G(-5,4)=(x1,y1)
H(-5,8)=(x2, y2)
midpoint=?
now,
(x,y)= x1+x2/2 y1+y2/2
-5-5/2 4+8/2
-10/2 12/2
-5 6
therefore the co ordinates of midpoint are(-5,6)

Sarah is playing a board game. Her score was -275 at the start of her turn. At the end of her turn, her score was -425. What was the change in Sarah's score (in points) from the start of her turn to the end?
Answer:
150 points
Step-by-step explanation:
Since they are asking for a change, first you need to subtract the greater number by the least number. So the equation now looks like -275 - (-425), solving this using integer skills will get you a answer of 150 points.
Answer: -150
Step-by-step explanation:
The change is obtained by subtracting the original term from the second term so you do -425 + 275 = -150, the change in Sarah’s score.
What is not a description of slope?
rise over run
the rate of change of a line
change in y over the change in x
the ratio of horizontal change compared to vertical change
Answer:
Option (d) is wrong.
Step-by-step explanation:
Slope is:
rise over runThe rate of change of a lineChange in y over the change in xThe ratio of vertical change to the horizontal change.It can be given by mathematically as follows :
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\text{and}\\\\m=\dfrac{dy}{dx}[/tex]
Hence, the option which is not a description of slope is (d) "the ratio of horizontal change compared to vertical change"
