Answer:
75 seconds
Step-by-step explanation:
Here, we want to get her time 6 weeks ago.
We shall have an exponential model to link this all up
The exponential model would look like;
y = I(1 - r)^n
where y is the present time
I is the initial time she started with which we are calculating
r is the rate of change which is 2% = 2/100 = 0.02
n is the week number which is 6 in this case
So we have;
66 = I(1 - 0.02)^6
66 = I(0.98)^6
I = 66/0.8858
I = 74.5 seconds
This is approximately 75 seconds
Her time 6 weeks ago is 75 seconds
Answer:
Step-by-step explanation:
Givens
Cost = 34498 + 33942x
Cost = 2614090
Solution
34498 + 33942x = 2614090 Subtract 34498 from both sides.
33942x = 2614090 - 34498
33942x = 2579592 Divide by 33942
x = 2579592/33942
x = 76
The number of employees expected to be hired is 76
Answer:
Parallel
Step-by-step explanation:
Let the required lines be y-x = 5 and y = x-1
If y-x = 5
y = x + 5
The slope m = 1
For the line y = x - 1
The slope m is also 1
Since the slope of both lines are the same, hence both liens are parallel
Answer:
12.53 units to the nearest hundredth.
Step-by-step explanation:
The formula for this length = √[ (x2 - x1)^2 + (y2 - y1)^2 ]
GH = √[ (12-6)^2 + (7-18)^2 ]
= √ ( 36 + 121)
= √(157)
= 12.53 units.
