Answer:
r = 3x + 1
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here
πr² = π(9x² + 6x + 1) ← divide both sides by π
r² = 9x² + 6x + 1 ← perfect square
r² = (3x + 1)² , thus
r = 3x + 1
Answer:
x = 4 ±9i
Step-by-step explanation:
x^2 - 8x + 97 = 0
Complete the square by subtracting 97 from each side
x^2 - 8x =- 97
Take the coefficient of x
-8 and divide by 2
-8/2 = -4
Then square it
(-4)^2 = 16
Add it to each side
x^2 - 8x + 16 = -97+16
(x-4)^2 = -81
Take the square root of each side
x-4 = ±sqrt(-81)
x-4 = ±9i
Add 4 to each side
x = 4 ±9i
SInce you are wanting to find the distance between the game store and furniture store, you will want to add 16.7 km and 18 km so that you will have the total distance between the two stores.
(Train station) 25.4 km (Game store) 16.7 km (Radio Tower) 18km (Furniture store)
34.7 km is your final answer.
Answer:
g(-3) = -13
Step-by-step explanation:
Plug in -3 for n in the equation:
g(n) = 3n - 4
g(-3) = 3(-3) - 4
Remember to follow PEMDAS. First, multiply, then subtract:
g(-3) = 3 * -3 = -9
g(-3) = -9 - 4
g(-3) = -13
-13 is your answer for g(-3).
