Answer:

Step-by-step explanation:

To determine the best estimate for the area under the curve we can use the area of boxes concept. It means we can estimate it by adding the area of the boxes .

It is easier to find the area of boxes as they are forming a rectangle .

Notice that

the length of the shaded area is 4 units (from 0.5 to 4.5)

Similarly the width of the shaded area is roughly 5 units (0 to 5)

we know that the area of a rectangle is length times width .

Rectangle because the boxes are roughly forming a rectangle with  l = 4 and w = 5

so area = 4·5

Area = 20 units ^2

ElenaW [278]

Answer:

85.36 far north from the center

10.36 far east from the center

Step-by-step explanation:

The extra direction taken in the north side is x

X/sin(360-315)=50/sin 90

Sin 90= 1

X/sin 45= 50

X= sin45 *50

X= 0.7071*50

X= 35.355 steps

X= 35.36

Then the west direction traveled

West =√(50² - 35.355²)

West = √(2500-1249.6225)

West= √1250.3775

West= 35.36 steps

But this was taken in an opposite west direction

From the center

He is 35.36 +50

= 85.36 far north from the center

And

25-35.36=-10.36

10.36 far east from the center

The centroid C divides the length of each median PY, ZQ, and XR into the ratio of 2:1 as shown in the diagram below

a) CY = 10
    PC = 2×10 = 20
    PY = 20+10 = 30

b) QC =10
    ZC = 10÷2 = 5
    ZQ = 10+5 = 15

c) PX = 20
    PQ = 2×20 = 40

Step-by-step explanation:

a^2+b^2=c^2

=> 5^2+b^2=8^2

=> 25+b^2=64

=> b^2=64-25

=> b^2=39

=> b=6.245
