Answer:
Percentage change in price = 13.80%
Step-by-step explanation:
Given that:
Original price = £57.99
Decreased price = £49.99
Difference = Original price - Decreased price
Difference = 57.99 - 49.99
Difference = £8.00
Percent change =
Percent change =
Percent change in price = 13.80%
Hence,
Percentage change = 13.80%
Answer:
1. False 2. True
Step-by-step explanation:
For a geometric sequence,
1. The sequence is :
3, 13, 23, 33,...
It is not geometric. It is false
2. The sequence is :
5, -25, 125, -625
So, the sequence is geometric as the common ratio is same. It is true.
F(2a)=35
f(2a)=(2a)^2-1=35
(2a)^2-1=35
add 1 both sides
(2a)^2=36
sqrt both sides
2a=+/-6
divde 2
a=+/-3
a=3 or -3
Answer:
V ≈ 714 in³
Step-by-step explanation:
The volume of a triangular prism can be found using the formula:
V = Bh, where B = the area of the base and h = the height of the prism. Since the base is a triangle, you will need to use the formula for area of a triangle: A = bh.
In this figure, the base of the triangle = 23.25 and the height of the triangle is 10.25. So, the area = ()(23.35)(10.25) ≈ 119 in²
With the B = 119 and the height of the prism = 6:
V = 119(6) = 714 in³
