Answer:

x ≈ 7.2

Step-by-step explanation:

Given a tangent- secant from an external point to the circle, then

the the square of the measure of the tangent is equal to the product of the external part of the secant and the entire secant, that is

x² = 4(4 + 9) = 4 × 13 = 52 ( take the square root of both sides )

x = \sqrt{52} ≈ 7.2 ( to the nearest tenth )

If f(x) = 7 (x-1) + 8 , what is the value of f (1)
Flauer [41]

Answer:

f(1) = 8

Step-by-step explanation:

Step 1: Define

f(x) = 7(x - 1) + 8

f(1) = x = 1

Step 2: Substitute and evaluate

f(1) = 7(1 - 1) + 8

f(1) = 7(0) + 8

f(1) = 8

5. A sum of money is divided among Ethan, Jun Wei
anastassius [24]

Answer:

$450

Step-by-step explanation:

Let E be the amount of money Ethan starts with, J be the amount Jun Wei starts with, and R be the amount Raj starts with. Let M be the total amount of money to start with.

To start:

E:J:R = 5:6:9

This means Ethan has 5/20 of M, the money to start with. This reduces to 1/4 of M.

Afterwards:

(E-50):J:R = 3:4:6

This means Ethan has 3/13 of the remaining money (which is M-50!) after giving up 50. So

E = (M/4), or 4E = M

and

(E - 50) = 3/13 * (M - 50)

We know 4E = M, so we can substitute that in:

(E - 50) = 3/13 * (4E - 50)E - 50 = (12/13)E - 150/13E - 650/13 = (12/13)E - 150/13(1/13)E = 500/13E = 500

That's how much money Ethan had to start with. But we're asked how much he has AFTER giving $50 away, so that's $450.
