<h3>Solution(s):</h3>

1) What distance did a car travel that went 70 mph for 6 hours?

Given:

70 miles = 1 hour

Multiply the RHS by 6 to see what distance was covered by the car in 6 hours.

70 miles = 1 hour
=> 70 x 6 miles = 6 hours
=> 420 miles = 6 hours

The car traveled 420 miles in 6 hours.

2) What is the perimeter of a rectangle with a length of 7 cm and a width of 4 cm?

Given:

Length: 7 cm
Breadth: 4 cm

Formula to find perimeter: 2(L) + 2(B)

Substitute the values into the formula to find the perimeter.

2(L) + 2(B)
=> 2(7) + 2(4)
=> 14 + 8
=> 22 cm

The perimeter of the rectangle is 22 cm.

Arlecino [84]

Answer:

Minimum 8 at x=0, Maximum value: 24 at x=4

Step-by-step explanation:

Retrieving data from the original question:

$f(x)=x^{2}+8\:over\:[-1,4]$

1) Calculating the first derivative

$f'(x)=2x$

2) Now, let's work to find the critical points

Set this

$2x=0\\x=0$

0, belongs to the interval. Plug it in the original function

$f(0)=(0)^2+8\\f(0)=8$

3) Making a table x, f(x) then compare

x| f(x)

-1 | f(-1)=9

0 | f(0)=8 Minimum

4 | f(4)=24 Maximum

4) The absolute maximum value is 24 at x=4 and the absolute minimum value is 8 at x=0.
