The first four terms are -6, -7, -9 and -13.
Step-by-step explanation:
- Step 1: Given first term, a(1) = -6 and the nth term, a(n) = 2a(n-1) + 5. FInd the first four terms.
⇒ a(1) = -6
⇒ a(2) = 2a(1) + 5 = 2 × -6 + 5 = -12 + 5 = -7
⇒ a(3) = 2a(2) + 5 = 2 × -7 + 5 = -14 + 5 = -9
⇒ a(4) = 2a(3) + 5 = 2 × -9 + 5 = -18 + 5 = -13
Answer:
45 - 43.7 = $1.3
Step-by-step explanation:
a) Kohl’s is selling the speaker for $60.00. Mrs. House has a Friends and Family discount coupon for 25% off.
This means that the amount that he would have to pay would be the cost of the speaker - 25% of this cost and multiplied by 100. It becomes
60 - (25/100 × 60) = 60 - 15 = $45
So she would be paying $45 at Kohl
b) Target purchased the speaker for $38.00 and marked it up by 15% to sell in the store. The price that she will pay at Target would be the sum of the price at which Target purchased it + 15% of this price. It becomes
38 + (15/100 × 38) = 38 + 5.7 = 43.7
So she would be paying $43.7 at Target.
c) she would get the best deal at Target because it is cheaper there. She would be saving
45 - 43.7 = $1.3
Answer:
486 centimeters³
Step-by-step explanation:
Surface area of a cube = 6s²
Where,
s = side length
Find the surface area of a cube-shaped jewelry gift box with a side length of 9 centimeters.
s = 9 centimeters
Surface area of a cube = 6s²
= 6 × 9²
= 6 × 81
= 486 centimeters³
Surface area of a cube-shaped jewelry gift box with a side length of 9 centimeters 486 centimeters³
