To get the answers you could either graph the rates or create a table. Creating a table is easier to understand, graphing is much faster. I attached pictures of the graphs. Y axis being amount of $ and x axis being the amount of shirts.

Second graph is for questions 8 and 9

first graph for question 10

The difference is that i took out shipping for question 10

Table explains 8 and 9 more easily

Help me please I’m having trouble with it

gavmur [86]

Given:

Measure of arcs 50°, 115° and 85°

To find:

The measure of the numbered angle 5.

Solution:

Let the missing arc measure be A.

The arc measure of a full circle is 360°

m(ar A) + 50° + 115° + 85° = 360°

m(ar A) + 250° = 360°

Subtract 250 from both sides.

m(ar A) = 110°

<em>If two chords intersects inside a circle, then the measure of the angle formed is half of the sum of intercepted arcs.</em>

$$\Rightarrow m\angle 5 =\frac{1}{2} (110^\circ+115^\circ)$

$$\Rightarrow m\angle 5 =\frac{1}{2} (225^\circ)$

$$\Rightarrow m\angle 5 =112.5^\circ$

The measure of the numbered angle is 112.5°.

YOOOO NEED HELP ASAP !!! GIVIN BRAINIEST

Answer:

Correct answer is: f(1) = - 21 , f(n) = - 3 · f(n -1)

Step-by-step explanation:

Given geometric sequence: -21, 63, -189, 567,.........................

Formula for n-th term or a₍ₙ₎ = f(n) = a₁ · q ⁽ⁿ⁻¹⁾ where a₁ is first term and q is quotient (ratio). Formula for (n-1) th term or a₍ₙ₋₁₎ = f(n-1) = a₁ · q ⁽ⁿ⁻²⁾

In this case a₁ = -21 and q = -3

a₍₁₎ = f(1) = -21 · (-3)⁽¹⁻¹⁾ = -21 · (-3)⁰ = -21

f(n) = q¹ · f(n - 1) = q¹ · a₁ q ⁽ⁿ⁻²⁾ = a₁ · q ⁽ⁿ⁻¹⁾ = f(n)

In this case q = -3

f(n) = -3 · f(n -1)

God with you!!!
