Answer:
2.73 divided by 30 is 0.091
Exponential
Step-by-step explanation:
So let’s start off by looking at how much x is growing by each time
X is growing by 8 each time
Next look at how much y is growing by
-6 to -24 is a difference of 18
-24 to -96 is a difference of 72
And lastly -96 to -384 is a difference of 288
So we can now say that it is not linear because a linear equation grows by a constant number (like adding)
To determine if it is exponential see if it is growing by a constant multiplier
24 divided by 6 is 4
96 divided by 24 is 4
384 divided by 96 is 4
It is exponentially growing by 4
Answer:
see explanation
Step-by-step explanation:
The perimeter is the sum of the 3 sides, that is
perimeter = 8 + 12 + 17 = 37 cm
To use Heron's formula for area (A)
A = 
where a, b and c are the lengths of sides and s the semi perimeter
s = 37 ÷ 2 = 18.5
let a = 8, b = 12 and c = 17, then
A = 
= 
= 
≈ 43.52 cm² ( to 2 dec. places )
Answer:
N times 4-1
Step-by-step explanation:
4 times number is not a squared number where you multiply- the number
by it's self and then you subtract 1
