(a) Estimate the area under the graph of f(x) = 2 cos(x) from x = 0 to x = π/2 using four approximating rectangles and right end

nirvana33 [79]

<span>first, we are going to define variables as the following:

a = 0
a = π/2
n = 4 rectangles

Δx = [ b - a ] / n ------>Δx = [ π/2 - 0 ] / 4 = π/8

right endpoints :
sum( seq( 4 cos(x) * π/8 , x , 0+π/8 , π/2 , π/8 ) ) = 3.163065 underestimate

left endpoints:
sum( seq( 4 cos(x) * π/8 , x , 0 , π/2-(π/8) , π/8 ) ) = 4.733861 overestimate

the reason because the actual estimate by integral as the following:
π/2
∫ 4cos(x) dx = 4

Rate of change between (2,11) and (8,14)

SCORPION-xisa [38]

Answer:

1/2

Step-by-step explanation:

the rate of change is = the change in y/ the change in x

if the points are (2, 11) and (8, 14)

Rate of change = (14-11) / (8-2) = 3 / 6 = 1/2

Tommy purchased a riding lawnmower with an original value of $2,500. If the value of the riding lawnmower decreases by $300 per

Eva8 [605]

Answer:

$1000.

Step-by-step explanation:

Let x represent number of years.

We have been given that Tommy purchased a riding lawnmower with an original value of $2,500. The value of the riding lawnmower decreases by $300 per year. We are asked to find the value of lawnmower after 5 years.

Since the value of the riding lawnmower decreases by $300 per year, so value of lawnmower decrease in 5 years would be 5 times $300.

The final value of lawnmower would be initial value minus value decreased in 5 years.

$\text{The value of the lawnmower after five years}=\$2500-\$300(5)$
