Answer:

(a) 25°

Step-by-step explanation:

The angle marked 93° is the average of the arcs intercepted by the secant lines.

(161° +AD)/2 = 93°

161° +AD = 186° . . . . . multiply by 2

AD = 25° . . . . . . . . . . .subtract 161°

A man receives an annual increase of #30000 and after a period of 10 years service, the man has the salary of #1014. Find his in

Paladinen [302]

I think you intended writing #30 as his pay rise instead of #30000. I solved the problem using #30 as his annual pay rise.

Answer:

The man's initial salary was #714

Step-by-step explanation:

Extracting the key information from the question:

*** A man got a pay raise for 10 years.

*** His current salary is #1,014

*** He gets a pay raise of #30 annually.

*** We are simply required to calculate his initial salary before he started receiving pay rise.

Now, To calculate his initial salary before he started receiving pay rise, let us denote that initial salary that we are currently unaware of by "a".

Since his salary as at today is #1,014 and he has also received this pay rise of #30 for 10 years, we can calculate his initial salary before he started receiving pay rise every year with the following equation:

a + 30(10) = 1014

That is -

Initial salary + [pay rise × number of years] = current salary.

a + 30(10) = 1,014

a + 300 = 1014

a = 1014 - 300

a = #714

Therefore the man's initial salary was #714

What is the simplest form of this expression w^2(-4w^2-2)+(-5w^2)(-2w^2-2)

VikaD [51]

Answer:
6w⁴ + 8w²

Explanation:
Before we begin, remember the following:
xᵃ * xᵇ = x⁺ᵇ
+ve * -ve = -ve
-ve * -ve = +ve
+ve * +ve = +ve

To solve this problem, we will follow the following steps:
1- get rid of the brackets using the distributive property
2- combine like terms

This can be shown as follows:
w²(-4w² - 2) + (-5w²)(-2w² - 2)
w²(-4w²) + w²(-2) + (-5w²)(-2w²) + (-5w²)(-2)
-4w⁴ - 2w² + 10w⁴ + 10w²
w⁴(-4+10) + w²(-2+10)
6w⁴ + 8w²

Hope this helps :)
