Answer:
Number of instructors are 225.
Step-by-step explanation:
Given:
Total number of employees at bright mind learning = 300
Number of instructors = 75%
We have to convert this percentage and find the number.
So,
can be written as
Now 75% of 300 employees are the instructors at Bright mind learning.
Can be written as
Number of instructors at Bright mind learning =225
f(x) = x^3 + 5x^2 - 4x - 20
The zeros of the polynomial function: x^3 + 5x^2 - 4x - 20 = 0
x^3 + 5x^2 - 4x - 20 = 0
x^2(x + 5) - 4(x + 5) = 0
(x^2 - 4)(x + 5) = 0
(x + 2)(x - 2)(x + 5) = 0
(x + 2) = 0; x = -2
(x - 2) = 0; x = 2
(x + 5) = 0; x = -5
Answer is the first one
x = -5, x = -2, x = 2
Answer : x = 40
move the constant to the right it changes to
3/4x = 23 + 7
then u add the numbers
23 + 7 = 30
3/4x = 30
after that u multiply both sides by 4/3
and you’ll get x = 40
Answer:
1.
Step-by-step explanation:
The cell phone experiments an exponential depreciation, which is defined by the following formula:
, for . (1)
Where:
- Initial cost, measured in monetary units.
- Depreciation rate, no unit.
- Time, measured in years.
- Current value of the cell phone, measured in monetary units.
If we know that and , then the exponential decay function that represents the situation is:
Which means that correct answer is 1.
