What is the rate for 4 shirts for $32:00

2 answers:

4 0

32/4 = 8
this means that each shirt costs 8 dollars

hope this helps

so x = x(8) or (for every shirt, multiply the number by 8)

The answer should be $8 if you are trying to find the unit rate. All you have to do is divide 32 by 4 and you get 8. Hope that helped.

Answer:

$\boxed{\sf \dfrac{41}{63}}$

Step-by-step explanation:

hi, it means that we have to compute

$\dfrac{2}{9}+\dfrac{3}{7}=\dfrac{7*2+3*9}{7*9}=\dfrac{14+27}{7*9}=\dfrac{41}{63}$

This question has several parts that must be completed sequentially. If you skip a part of the question, you will not receive an

Answer:

Step-by-step explanation:

Given that there is a function of x,

$f(x) = 2sin x + 2cos x,0\leq x\leq 2\pi$

Let us find first and second derivative for f(x)

$f'(x) = 2cosx -2sinx\\f"(x) = -2sinx-2cosx$

When f'(x) =0 we have tanx = 1 and hence

a) f'(x) >0 for I and III quadrant

Hence increasing in $(0, \pi/2) U(\pi,3\pi/2)\\$

and decreasing in $(\pi/2, \pi)U(3\pi/2,2\pi)$

$x=\frac{\pi}{4}, \frac{3\pi}{4}$

$f"(\pi/4)$

Hence f has a maxima at x = pi/4 and minima at x = 3pi/4

b) Maximum value = $2sin \pi/4+2cos \pi/4 =2\sqrt{2}$

Minimum value = $2sin 3\pi/4+2cos 3\pi/4 =-2\sqrt{2}$

f"(x) =0 gives tanx =-1

$x= 3\pi/4, 7\pi/4$

are points of inflection.

concave up in (3pi/4,7pi/4)

and concave down in (0,3pi/4)U(7pi/4,2pi)

Andrej [43]

I have no idea what to do in problem 1

but I will do problem 2

A. 2⁵ = 32 (2×2×2×2×2=32)

B. 4³/2 = 32 (4×4×4=64 and then 64÷2=32

the others are not equal to 32
