Answer:
Two zeros are 17 and -5
Step-by-step explanation:
Given:
f(x) = x² - 12x - 85
Find:
Zeros of the function
Computation:
f(x) = x² - 12x - 85
f(x) = x² - (17 - 5)x - 85
f(x) = x² - 17x + 5x - 85
f(x) = x(x - 17) + 5(x - 17)
f(x) = (x - 17) (x + 5)
So,
x - 17 = 0 , x + 5 = 0
So,
x = 17 , x = -5
Two zeros are 17 and -5
Answer:
(0,4)
(1/2,7)
(2.25,7)
(3,4)
Step-by-step explanation:
you want to take each point and subtract five from the 'x' value and add two to the 'y' value
(5,2) → (5-5, 2+2) → (0,4)
(5.5,5) → (5.5-5, 5+2) → (0.5,7)
(7.25,5) → (7.25-5, 5+2) → (2.25,7)
(8,2) → (8-5, 2+2) → (3,4)
Answer:8 y
Step-by-step explanation:
Answer:
breadth = 25m
length= 35m
Step-by-step explanation:
perimeter is distance all round a figure
in a rectangle we have two pairs of opposite but equal lines
breadth = 2x( because of the two breadths in a rectangle) - 20
length = 2x( because of the two lengths in a rectangle)
perimeter = 2x + 2x - 20
120 = 4x - 20
120 + 20 = 4x
140 = 4x
35 = x
to get the dimensions, we have to divide by 2 as we took both parts of each dimension
breadth =<u> 2x - 20</u>
2
<u>=2(35) - 20</u>
2
<u>= 70 - 20</u>
2
<u>= 50m</u>
2
= <u>25m</u>
length =<u> 2x</u>
2
<u>= 2(35)</u>
2
<u> = 70m</u>
2
= <u>35m</u>

Answer:
- $38,500
- $1,400
Step-by-step explanation:
1. According to the Accrual Principle of Accounting, revenue should only recognized when the goods or services for which it was paid for have been delivered. In other words, revenue should only be recognized when earned.
As of December 1, 20X1, Ginzel had only completed 7 of the 20 reports so the revenue recognized should be for the completed reports alone.
Total revenue for 20 reports = $110,000
Revenue for 7 reports = 7/ 20 * 110,000
= $38,500
2. The Accrual principle also applies to expenses and states that expenses should only be accounted for when incurred. As the $4,000 relates to all the reports, it should be apportioned evenly.
The costs of extraction and conversion of data for the year should therefore be;
= 7/20 * 4,000
= $1,400
