Step-by-step answer:

Given:

Initial monthly salary = $5000

New salary = 10% less

Salary a year after = 15% more

Solution:

New salary

= 5000 * (100-10)%

= 5000 * 90%

= 5000 * 90/100

= 4500

Salary a year after

= 4500 * (100+15%)

= 4500 * 115%

= 4500 * 115/100

= 45*115

= 5175

Use the properties of exponents to rewrite the expression.<br> (-3yz)(-3yz)(-3yz)(-3yz)

Lera25 [3.4K]

Answer:

Answer is 81y^4z^4

Step-by-step explanation:

The expression is (-3yz) (-3yz) (-3yz) (-3yz).

Since all the four terms have power 1:

(-3yz)^1 (-3yz)^1 (-3yz)^1 (-3yz)^1

We know that we can add the powers if the terms have same base

So,

=(-3yz)^1+1+1+1

=(-3yz)^4

=(-3)^4(y)^4(z)^4.

If the power is an even number than the negative sign changes into positive sign.

=3^4y^4z^4

=81y^4z^4

Thus the answer is 81y^4z^4....

Charlie is at a small airfield watching for the approach of a small plane with engine trouble. He sees the plane at an angle of

Akimi4 [234]

Refer to the diagram shown below.

Let d = the horizontal distance from Charlie to the plane.
By definition,
tan(32°) = 1694.8/d
1694.8/d = 0.6249
d = 1694.8/0.6249 = 2712.2 ft

Answer: 2,712.2 ft
