<span>We know that the circumference of a circle is equal to pi times the diameter of the circle. Therefore, assuming this crater to be circular in shape, we can divide the circumference by pi, in this case 9033*7/22, yielding an answer of 2874.1 feet after rounding.</span>

Determine the value of x and y in the following systems of equations5x-2y=4 ; -2x+y=2.
V125BC [204]

Answer:(x,y)=(8,18)

Step-by-step explanation:

Given

5x-2y=4-------1

Second Equation

-2x+y=2-----2

Now multiply equation 2 by 2 and it to equation 1

5x-4x+0=8

x=8

substitute it in equation 1

5\times 8-2\times y=4

36=2y

y=18

Therefore

(x,y)=(8,18)

How much of the 8% solution should we use to make 100g of a 3% solution?
sp2606 [1]
Suppose x grams of 8% solution should be mixed to make 100 g of 3% solution.
here we shall have:
the amount of 3% solution in the 100 g will be:
3/100*100=3 grams
the the equation will be, 8% of what quantity becomes 3g?
(8/100)*x=3
hence solving for x we shall have:
0.08x=3
x=3/0.08
x= 37.8 grams
The implication of this is that, when you have 37.5 grams of 8% solution, that will contain 3  of pure chemical and hence when you add more solvent on top of 37.5 g until you reach 100g, that will be 3% solution.

Find all critical numbers of the function <img src="https://tex.z-dn.net/?f=g%28x%29%3Dx%5E%7B%5Cfrac%7B3%7D%7B4%7D%20%7D-2x%5E%
postnew [5]

Differentiate g using the power rule:

g'(x) = \dfrac34 x^{\frac34-1} - 2\cdot\dfrac14 x^{\frac14-1}

g'(x) = \dfrac34 x^{-\frac14} - \dfrac12 x^{-\frac34}

g'(x) = \dfrac14 x^{-\frac34} \left(3 x^{\frac12} - 2\right)

g'(x) = \dfrac{3\sqrt x - 2}{4 x^{\frac34}}

The critical points of g occur where g' is zero or undefined.

We have

g'(x) = 0 \implies 3\sqrt x - 2 = 0 \implies \sqrt x = \dfrac23 \implies \boxed{x = \dfrac49}

and the derivative is undefined for

\dfrac1{g'(x)} = 0 \implies 4x^{\frac34} = 0 \implies \boxed{x=0}
