Answer:

First we need to convert those feet into inches.

0.5 x 12 = 6 inches

1.5 x 12 = 18 inches

4 inches is just 4 inches

Now we just find the surface area:

6 x 4 = 24

24 x 2 = 48

18 x 4 = 72

72 x 2 = 144

6 x 18 = 108

108 x 2 = 216

Now lets add all the given areas:

48 + 144 + 216 = 408 square inches (just do the number since they tell you not to use the unit)

Please, Answer is needed.
Yuki888 [10]

Answer:

540 mins | 9 hours | 540, 9

420 mins | 7 hours | 420, 7

300 mins | 5 hours | 300, 5

180 mins | 3 hours | 180, 3

Step-by-step explanation:

1 hour = 60 mins

To convert hours into minutes, multiply the number of hours by 60 minutes:

9 hours × 60 mins = 540 mins

7 hours × 60 mins = 420 mins

5 hours × 60 mins = 300 mins

3 hours × 60 mins = 180 mins

Ex 2.8<br> 3. find the maximum value of y for the curve y=x^5 -3 for -2≤x≤1
harkovskaia [24]
y=x^5-3\\ y'=5x^4\\\\ 5x^4=0\\ x=0\\ 0\in [-2,1]\\\\ y''=20x^3\\\\&#10;y''(0)=20\cdot0^3=0

The value of the second derivative for x=0 is neither positive nor negative, so you can't tell whether this point is a minimum or a maximum. You need to check the values of the first derivative around the point.
But the value of 5x^4 is always positive for x\in\mathbb{R}\setminus \{0\}. That means at x=0 there's neither minimum nor maximum.
The maximum must be then at either of the endpoints of the interval [-2,1].
The function y is increasing in its entire domain, so the maximum value is at the right endpoint of the interval.

y_{max}=y(1)=1^5-3=-2

A patient was supposed to take 560 mg of medicine but only tool 420 mg.What percent of the medicine did the patient take?
Stolb23 [73]
75% I think.

because if you do 560 - 420 you get 140.

140 / 560 x 100 = 25

which means there is a 25% decrease, so they took 75%.
