When x = 6.4, y=117, therefore

15*6.4 + b = 117

b = 117 -  96 = 21

Confirm this value by checking (6.6, 120).

15*6.6 + 21 = 120 (Correct)

Answer: b = 21

A rectangular room has a width of 5 yards and length of 6 yards. How many square-feet carpet will be required for carpeting the
Sindrei [870]

Answer:

Option B 270\ ft^{2}

Step-by-step explanation:

we know that

The area of the rectangle room, is equal to

A=LW

where

L is the length

W is the width

we have

L=6\ yd

W=5\ yd

Remember that

1 yard= 3 feet

Convert yards to feet

L=6*3=18\ ft

W=5*3=15\ ft

The area is equal to

A=(18)(15)=270\ ft^{2}

Volume of a cylinder pi 3.14 d=2r h=6cm d=12cm
alex41 [277]

Answer:

V = 678.24cubic cm

Step-by-step explanation:

Volume of a cylinder

V = πr^2h

V - volume of a cylinder

π - pie

r - radius of a cylinder

h - height of a cylinder

Given:

π - 3.14

h - 6

d = 12

d = 2r

Divide both sides by 2

d/2 = 2r/2

d/2 = r

r = d/2

r = 12/2

r = 6

Insert the values into the formula

V = πr^2h

V = 3.14 * 6^2 * 6

= 3.14 * 36 * 6

= 678.24cubic cm

A radar gun was used to record the speed of a swimmer (in meters per second) during selected times in the first 2 seconds of a r
Natalka [10]
Trapezoidal is involving averageing the heights
the 4 intervals are
[0,4] and [4,7.2] and [7.2,8.6] and [8.6,9]

the area of each trapezoid is (v(t1)+v(t2))/2 times width

for the first interval
the average between 0 and 0.4 is 0.2
the width is 4
4(0.2)=0.8

2nd
average between 0.4 and 1 is 0.7
width is 3.2
3.2 times 0.7=2.24

3rd
average betwen 1.0 and 1.5 is 1.25
width is 1.4
1.4 times 1.25=1.75

4th
average betwen 1.5 and 2 is 1.75
width is 0.4
0.4 times 1.74=0.7

add them all up
0.8+2.24+1.75+0.7=5.49

5.49
t=time
v(t)=speed
so the area under the curve is distance

For the inverse variation equation p = StartFraction 8 Over V EndFraction, what is the value of V when p = 4?
dedylja [7]

Answer:

V=2

Step-by-step explanation:

For the inverse variation equation p = StartFraction 8 Over V EndFraction, what is the value of V when p = 4?

P=8/V

Inverse variation is expressed as

y=k/x

Where,

k= constant.

From the question,

P=8/V

Where,

8=constant

What is the value of V when p=4

P=8/V

Make V the subject of the formula

pV=8

V=8/p

Substitute the value of p

V=8/4

V=2
