Answer:
5m² - 6m + 1
Step-by-step explanation:
f(x) = 5x² + 4x - 5
substituting value,
f(m-1) = 5(m-1)² + 4(m-1) - 5
so,
5(m-1)² + 4(m-1) - 5
= 5(m²-2m+1) + 4m -1 - 5
= 5m² - 10m + 5 + 4m - 4
= 5m² - 6m + 1
Answer:
A.) the balance is payed off during the grace period
Step-by-step explanation:
Paying only the minimum payment would cause the remainder of the balance to draw interest charges, whether paid during the grace period or before the due date.
Paying off the balance during the next billing cycle will still result in interest charges for the current billing cycle.
Paying off the balance during the grace period, however, will not result in interest charges.
Answer:
Step-by-step explanation:
The line that passes through the two points (6, -23) and (11, r) has a slope of 4.
We want to determine the missing value of r.
We can use the slope formula:
Let (6, -23) be (x₁, y₁) and let (11, r) be (x₂, y₂). The final answer should be 4. Therefore:
Simplify and evaluate:
Multiply both sides by 5:
Therefore:
Answer:
Full drum 80 dollars
one lid missing
earn 10 dollars less
Step-by-step explanation:
We need to find the surface area
SA = 2 pi r^2 + 2 pi rh
The diameter is 2 so the radius = 2/2 =1
SA = 2 * pi * 1^2 + 2 * pi * 1 * 3
= 2 pi + 6pi
= 8pi
Using pi = 3.14
SA = 8 *3.14 = 25.12 ft^2
We get 3.18 per ft^2
25.12 * 3.18 =79.88
To the nearest dollar
80 dollars
If one of the lids is missing
SA = pi r^2 + 2 pi rh
pi + 6pi
7 pi
Using pi = 3.14
SA = 7 *3.14 = 21.98 ft^2
We get 3.18 per ft^2
21.98 * 3.18 =69.90
To the nearest dollar
70
The difference is 10 dollars
D & E
D) if you divide the ratios by 2 you get 1:6
E) if you multiply each ratio by 4 you get 8:48
You can’t divide or multiply any of the other numbers with 2 and 12 (together) to get you the other answers
