The price of a tablet was increased from $180 to $207. What was the percent of increase?
Fudgin [204]

Answer:

15%

Step-by-step explanation:

The price of the tablet was increased from $180 to $207.

Increase = $207 - $180

= $27

Therefore,

Percentage increase = increase/initial amount x 100%

That’s $27/$180 x 100%

0.15 x 100

15%

The percentage increase was 15%

PLEASE HELO ME AND EXPLAIN PLEASE. AND PLEASE SHOW IN STEPS!! i will mark brainliest if you get it correct!
Dimas [21]

Step-by-step explanation:

The height of the swipe card is given by :

h(t)=-3t^2+15t+18 .....(1)

We need to find the maximum height of the swipe card and the time to reach the maximum height.

For maximum height, put dh/dt = 0

So,

\dfrac{d}{dt}(-3t^2+15t+18)=0\\\\-9t+15=0\\\\t=\dfrac{15}{9}\\\\t=1.67\ s

It will take 1.67 seconds to reach the maximum height.

Now, put t = 1.67 s in equation (1).

h(1.67)=-3(1.67)^2+15(1.67)+18\\\\=34.68\ feet

Hence, the maximum height of the swipe card is 34.68 feet and the time to reach this height is 1.67 s.
