Answer:
23 m and 15 m
Step-by-step explanation:
THE BASE OF A RECTANGLE IS 8 M GREATER THAN THE HEIGHT, THE AREA MEASURES 65 SQUARE METERS HOW MUCH DO THE BASE AND HEIGHT MEASURE?
Let the height of the rectangle is h.
Base = 8+h
Area of the rectangle, A = 65 m²
We need to find the base and height of the rectangle. The area of a rectangle is given by :
A = bh
So,

Neglecting negative value, h = 15 m
Base = 8+15 = 23 m
So, the base and height of the rectangle is 23 m and 15 m respectively.
The slope of the function is given by its derivative. You want to find the values of x such that the derivative is between -1 and 1.
... f'(x) = 0.4x +5
... -1 < 0.4x +5 < 1 . . . . . your requirement for slope
... -6 < 0.4x < -4 . . . . . . subtract 5
... -15 < x < -10 . . . . . . . multiply by 2.5
Any value of x that is between -15 and -10 will be one where the tangent line has a slope between -1 and 1.
_____
The graph shows tangent lines with slopes of -1 and +1. You can see that the slope of the graph of f(x) is between those values when x is between the tangent points.
Answer:
$250
Step-by-step explanation:
Let x = amount he started with in his drawer
x + $823.27 - $734.87 = $338.40
$823.27 would be added because it is money going in
$734.87 would be subtracted because it is the money going out
solve for x
x = $250
It is much too low as if he runs 4 every year for the past 11 years he’s ran about 44 marathons and each marathon is 26 miles
Answer:
45m/hr
Step-by-step explanation:
Divide 270 by 6 to determine the unit rate.

Therefore, the unit rate is 45 miles per 1 hour.
