The 11 foot long bed of a dump truck loaded with debris must rise an angle of degrees before the debris will spill out. Approxim
Ymorist [56]

Answer:

The answer is below

Step-by-step explanation:

The question is not complete. The complete question is:

The 12 foot long bed of a dump truck loaded with debris must rise an angle of 30 degrees before the debris will spill out. Approximately how high must the front of the bed rise for the debris to spill out.

Solution:

Let x be the height of the front of the bed rise needed to be raised for the debris to spill out. We can find x using trigonometric identities. That is:

sin θ = opposite / hypotenuse

Using trigonometric identities, we can get that:

sin(30) = x / 12

This gives:

0.5 = x / 12

Cross multiplying the terms to get:

x = 12 * 0.5

x = 6 ft

Therefore the front of the bed rise must be raised 6 ft for the debris to spill out.

Find the fifth term in the sequence that is defined as follows an=n^2+2
Vedmedyk [2.9K]

Answer:

a(5) = 2 + 5^2 = 2 + 25 = 27

Step-by-step explanation:

This sequence is defined as a(n) = 2 + n^2.

Thus, a(1) = 2 + 1^2 = 2 + 1 = 3

Then a(5) = 2 + 5^2 = 2 + 25 = 27

-3(y+3)=2y+3 <br> Please solve this question
NARA [144]

Answer:

y=-2.4y

Step-by-step explanation:

First you want to restate the problem.

-3(y+3)=2y+3

Now distribute the negative.

-3y-9=2y+3

Add 3y to both sides.

-9=5y+3

Subtract 3 from both sides.

-12=5y

And solve.

-2.4=y
