The answer is false. if the quantities combine to make zero
Answer:
8. 6 shirts ($61)
9. $61
10. 32 shirts (256)
Step-by-step explanation:
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
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>



The measure of the numbered angle is 112.5°.
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!!!
