Assuming that you’re meant to distribute (you didn’t list expressions), this would be your answer:
-12x + 20
Hope this helps!
2(cos2x - sin2x)
Step-by-step explanation:
Y = sin2x + cos2x
Differentiate wrt x
dy/dx = cos2x . 2 - sin2x . 2
= 2(cos2x - sin2x)
I think there are no solutions but I could be wrong (╥ω╥`)
So the growth factor is the base of the exponential term, so the base of y = 34 * 4^x is 4.
the initial amount is the amount at x = 0
y = 15 * 3^xy = 15 * 3^0y = 15 * 1y = 15 is the initial amount
the decay factor of y=17×0.2^x is same as the growth factor, it is 0.2
Answer:
The cost of the electric scooter after the discount and
sales tax will be: $248.24
Step-by-step explanation:
The regular price of an electric scooter = $290
Discount = 20%
The discount price = 20% × 290
= 20/100 × 290
= $58
The price after the discount = $290 - $58 = $232
Sales tax = 7%
Sales tax amount = 7% × 232
= 7/100 × 232
= $16.24
The cost after the discount and sales tax = $232 + $16.24
= $248.24
Thus, the cost of the electric scooter after the discount and
sales tax will be: $248.24
