Answer:

i. The distance between the balloon and canoe is 16.8 meters.

ii. The situation can be represented by: -12 + d = 4.8

Step-by-step explanation:

Let the surface of the lake be zero. Then any position above it is taken to be positive, while any position below is taken as negative.

So that,

the balloon's vertical position = 12 meters

the sunken canoe's position = -4.8 meters

Given that the distance between the balloon and the canoes is d, then:

d = balloon's position - canoe's position

  = 12 - (-4.8)

  = 12 + 4.8

d  = 16.8

The distance between the balloon and canoe is 16.8 meters.

Thus,

d = 12 -(-4.8)

d = 12 + 4.8

-12 + d = 4.8

The situation can be represented by: -12 + d = 4.8

The graph shows the speed of sams car over time which best describes what is happening in section c
JulsSmile [24]
The graph is missing, so I am using a graph for a similar question.

It migh even be the same question, but the important thing is that I am going to explain you the situation in several sections of this diagram and so you will be able to work this kind of problems by  your selfl.

The graph is attached (see the figure).

The graph shows the evolution of the speed (vertical-axis) over time (horizontal-axis).

In the section A, the speed increases linearly: so the car is speeding up uniformly (constant acceleration).

In the section B, the line is horizontal which shows that the speed is constant. That is a uniform motion.

In the section C, the speed is decreasing uniformly, so the car is slowing down with uniform negative acceleration.

So, for this graph, the answer is: in the setion C. the car is slowing down (uniformly).

Find the x value 4x-28 9x
andriy [413]

Answer: -5.6

Step-by-step explanation:

Simplifying

(4x + -28) = 9x

Reorder the terms:

(-28 + 4x) = 9x

Remove parenthesis around (-28 + 4x)

-28 + 4x = 9x

Solving

-28 + 4x = 9x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-9x' to each side of the equation.

-28 + 4x + -9x = 9x + -9x

Combine like terms: 4x + -9x = -5x

-28 + -5x = 9x + -9x

Combine like terms: 9x + -9x = 0

-28 + -5x = 0

Add '28' to each side of the equation.

-28 + 28 + -5x = 0 + 28

Combine like terms: -28 + 28 = 0

0 + -5x = 0 + 28

-5x = 0 + 28

Combine like terms: 0 + 28 = 28

-5x = 28

Divide each side by '-5'.

x = -5.6

Simplifying

x = -5.6

Which expression is equivalent to r to the 9th over r to the 3rd
alisha [4.7K]

Answer:

r^{6}

Step-by-step explanation:

To make this a bit easier to see, we'll expand that expression.

R to the 9th is just r times itself 9 times. R to the third is r times itself 3 times.

(excuse my bad formatting)

<u>The expression:</u>

<u>r • r • r • r • r • r • r • r • r • 1</u>

             r • r • r • 1

Remember, anything and everything has a coefficient or denominator of 1.

So, we can cancel 3 r's from the numerator and denominator.

<u>r • r • r • r • r • r • 1</u>

             1

Simplify....

\frac{1r^{6}}{1}

That just equals r^{6}.

Help please. Im trying to do my homework but i don't understand how to.
Neko [114]
V = (4/3) pi  r^3

9.  V = (4/3)(3.14)(7.62)^3 = 1852.4  meters^3
10. V = (4/3)(3.14)(33/2)^3 = 18,807.0  inches^3
11. V = (4/3)(3.14)(18.4/2)^3 = 3260.1  feet^3
12. V = (4/3)(3.14)(sqrt3)/2)^3 = 2.7 cm^3
13. C = 2*pi*r ;   24 = 2 * 3.14 * r;   24/6.28 = r ; r = 3.82
   V = (4/3)(3.14)(3.82)^3 = 233.4 in^3
14.V = (4/3)(3.14)(35.8)^3 = 192,095.6  mm^3

I can't read # 15 but follow the steps above.
