The answer is 15 feet 7 inches :)

1 foot = 12 inches

so

6 feet + 8 feet = 14 feet

10 inches + 9 inches = 19 inches

19 inches = 1 foot 7 inches

14 feet + 19 inches = 15 feet 7 inches

I need help on number 2
Nina [5.8K]

9514 1404 393

Answer:

  a. 405

  b. -2

  c. 5

  d. 43

Step-by-step explanation:

I don't like doing arithmetic any more than you do, so I let a calculator do it for me. A spreadsheet works well for this, too. The function values are shown in the attachment.

Put the function argument where the variable is and do the arithmetic.

  a. h(4) = 5·3^4 = 405

  b. d(2) = 7 -9(2 -1) = -2

  c. h(0) = 5·3^0 = 5

  d. d(-3) = 7 -9(-3 -1) = 43

Make z the subject 9d= 6z - 5d
yarga [219]

Answer:

z=2\frac{1}{3}d

Step-by-step explanation:

9d=6z-5d

6z=9d+5d

6z=14d (combine like terms)

z=2\frac{1}{3}d

What force would have been applied to the bus from t=16 s to t=21 s? Assume the mass of the bus was 50 kg.
Svetllana [295]

Applying Newton's Second Law, it is found that the force, in Newtons, is given by:

F = 10[v(21) - v(16)]

Newton's Second Law states that Force, in Newtons, is <u>mass times acceleration</u>, that is:

F = ma

In this problem, mass of 50 kg, thus m = 50

Acceleration is <u>change in velocity divided by change in time</u>, that is:

a = \frac{\Delta_v}{\Delta_t}

In this problem, we don't know the velocities, but know that time is from 16s to 21s, thus:

\Delta_t = 21 - 16 = 5

\Delta_v = v(21) - v(16)

Thus, the force is given by:

F = ma

F = m\frac{\Delta_v}{\Delta_t}

F = 50\frac{[v(21) - v(16)]}{5}

F = 10[v(21) - v(16)]

Math Homework please help!
rewona [7]

Answer:

30....:)

Step-by-step explanation:

So looking at the graph. L to the midpoint of K is 15.

lets ignore N.

The graph has a line between k to the midpoint of L.  So does L to the midpoint of k, which was 15.

This line means they are parrelel, so we can conlude that they both equal 15.

Adding the two together, we find KL is 30 in length.

The graph says KL is parrelel to JM.

So we can conclude that JM is 30.

<u>That looks like D on your answer sheet</u>

The only thing I am not sure of is what the N has to do with the answer.

They give you the value of N, and say the use N, however you do not need N to find the answer.

I think that the answer is 30, and it is included on the answer sheet as well. But fair warning that N did not have a use in it.

Hope this helps :)
