They are inversely proportional hence v=s/t
Answer:
4 pounds, 14 ounces
Step-by-step explanation:
he said triple = *3
converting all the pounds to ounces, 1 pound is 16 ounces
16+10=26
26*3=78
78/16
4 pounds, 14 ounces
Answer:
- increasing: (π/2, 3π/2)
- decreasing: [0, π/2) ∪ (3π/2, 2π]
- minimum: -16 at x=π/2
- maximum: 16 at x=3π/2
Step-by-step explanation:
If all you want are answers to the questions, a graphing calculator can provide them quickly and easily. (see attached)
___
If you need an algebraic solution, you need to find the zeros of the derivative.
f'(x) = -16cos(x)sin(x) -16cos(x) = -16cos(x)(sin(x) +1)
The product is zero where the factors are zero, at x=π/2 and x=3π/2.
These are the turning points, where the function changes from decreasing to increasing and vice versa.
(sin(x)+1) is non-negative everywhere, so the sign of the derivative is the opposite of the sign of the cosine function. This tells us the function f(x) is increasing on the interval (π/2, 3π/2), and decreasing elsewhere (except where the derivative is zero).
The function local extrema will be where the derivative is zero, so at f(π/2) (minimum) and f(3π/2) (maximum). We already know that cos(x) is zero there, so the extremes match those of -16sin(x).
Answer: C
Step-by-step explanation:
The answer would be C because you have to look at the two closest perfect squares that the number is in between. 47 is in between six squared (36) and seven squared (49). That is why the answer would be somewhere between six and seven.
<span>What is the surface area of the figure?
0.5x0.5=0.25
0.4x0.5=0.2 that for two so do that again 0.2+0.2=0.4
0.25+0.4= 0.65
A
I hope this helps</span>
