Answer: 3/8 (Keep Change Flip)
Step-by-step explanation: -3/10 divided by 4/5, Keep Change Flip = -3/10 x -5/4 = 15/40 simplified to 3/8. Two negetives equal a positive.
Answer:
Step-by-step explanation:
Data Given: m = 70 kg , g = 9.8 ms^-2, h =10m.
For this case we can use the following formula:

For this case we need to find an expression for the force in terms of the distance. And since on this case the total distance is 10 m long we can write the expression like this:

The only acceleration on this case is the gravity and if we replace the values given we got:

Now we can find the required work with the following integral:


Answer:
Step-by-step explanation:
Let h represent the number of hours of babysitting.
C represents the total cost of babysitting for h hours.
For babysitting, Nicole charges a flat fee of $3, plus $5 per hour. Therefore, the equation would be
C = 5h + 3
Comparing the equation with the slope intercept form, y = mx + c,
The slope = 5
The y intercept = 3
If she babysits for 5 hours, the cost would bee
C = 5 × 5 + 3
C = $28
Answer:
A = 24t² + 2t
Step-by-step explanation:
The shaded area (A) is calculated as
A = area of outer square - area of rectangle
= (5t)² - t(t - 2)
= 25t² - t² + 2t
= 24t² + 2t
