Answer:
A = x^2 + 5x - 14
Step-by-step explanation:
A = L × W
A = (x+7) × (x-2)
A = x^2 + 7x - 2x - 14
Answer:
y = sin( x/2)
Step-by-step explanation:
The amplitude is 1
The period is 4pi
y = A sin ( Bx)
where A is the amplitude and B is 2pi/ period
y = 1sin (2pi/ 4pi x)
y = sin( x/2)
From indices : when you have a fraction like 3⁶/5
we can also write it as (5√3)^6
and we were given (c√a )^b
meaning that anywhere the letters are, we put them as the numbers there.
therefore: a = 3 , b = 6 , c = 5
Hope this helps and you understood it.
you're super free to ask any more questions eh.
Good luck ✅.

Step-by-step explanation:
<u>Recursive Formula for Arithmetic Sequences</u>
- <u />

represents the nth term
represents the preceding term
represents the common difference
<u>Explicit Formula for Arithmetic Sequences</u>
- <u />

represents the nth term
represents the 1st term
represents the common difference
<u>Ernest's Schedule Recursive Formula</u>
We can see that the common difference is
because for each week, Ernest swims 0.25 more kilometers than the preceding one. Therefore, the recursive formula for Ernest is 
<u>Ernest's Schedule Explicit Formula</u>
Given our common difference
from earlier and the fact that
is our first term, the explicit formula for Ernest is 
<u />
<u>Denise's Schedule Recursive Formula</u>
We can see that the common difference is
because for each week, Denise swims 0.5 more kilometers than the preceding one. Therefore, the recursive formula for Denise is 
<u>Denise's Schedule Explicit Formula</u>
Given our common difference
from earlier and the fact that
is our first term, the explicit formula for Denise is
