Answer:

3x³+3x so C

Step-by-step explanation:

Multiply both the given equations

x²(3x) = 3x³

What is the equation for the line that has a slope of 0 and passes through the point (3, 7)?

Harrizon [31]

Answer:

Step-by-step explanation:

PART 1

y=mx+b

m is slope and slope is 0 sooo

y=0x+b

it passes through (3,7)

7=0(3)+b

7=0+b

b=7

y=0x+7

so just y=7

PART 2

y=mx+b

y=1/5x+b

1/2=1/5(-2/3)+b

1/2=-2/15+b

1/2+2/15=b

15/30+4/30=b

19/30=b

y=1/5x+19/30

Emily has x amounts of apples, Peter has 4 apples less than Emily and Joshua has 2 times the number of apples of Peter. The tota

VladimirAG [237]

Answer:

Emily: 13, Peter: 9, Joshua: 18

Step-by-step explanation:

Emily = x

Peter = Emily - 4 = x - 4

Joshua = 2(Peter) = 2(x - 4)

Total = 40 = Emily + Peter + Joshua = (x) + (x - 4) + 2(x - 4)

40 = 2x - 4 + 2x -8

40 = 4x - 4 - 8

40 = 4x - 12

52 = 4x

x = 13

Emily = 13

Peter = 13 - 4 = 9

Joshua = 2(13 - 4) = 2(9) = 18

13 + 9 +18 = 40

A mountain is in the shape of a cone whose height is about 3.7 kilometers and whose base radius is about 3 kilometers. Approxima

Lelu [443]

Answer:

34.54 $km^{3}$

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Height (h) = 3.7 km

Base radius (r) = 3 km

We can calculate the volume of mountain by using following formula,

So, volume of cone = (1/3)π $r^{2}$ h

By putting the value in the formula, we get

= (1/3) π × $3^{2}$ × 3.7

= 11.1π

= 34.54 $km^{3}$

Hence, the volume of the mountain is 34.54 $km^{3}$ .
