Answer:

2/5 cups of silver oxide

1/10 cups of water

1/10 cups of potassium

Step-by-step explanation:

5+ 5 + 10 + 10+ 20 = 50

there are 50 total cups

now we must find the number to divide 50 by to get the 1 cup that we need

50 / 50 = 1

Now that we know what to divide by to get the quantities for 1 cup of solution, time to get the quantities

there are 20 cups of Silver oxide

20 / 50 = 2/5 cups

there are 5 cups of water

5 / 50 = 1/10 cups

there are 5 cups of potassium

5 / 50 = 1/10 cups

Find the formula for an exponential function that passes through the two points give.

Ksenya-84 [330]

Answer:

$y=3(2)^{x}$

Step-by-step explanation:

Given.

Two points are given.

$(x, y)=(-1,\frac{3}{2})$ and $(x, y)=(3,24)$

An exponential function is in the general form.

$y=a(b)^{x}$ -------(1)

We know the points $(-1,\frac{3}{2})$ and $(3,24)$

put the first point value in equation 1

$\frac{3}{2}=a(b)^{-1}$

$\frac{3}{2}=\frac{a}{b}$

$a=\frac{3}{2}\times b$ --------(2)

put the second point value in equation 1

$24=a(b)^{3}$ ----------(3)

Put the a value from equation 2 to equation 3

$24=\frac{3}{2}\times b(b)^{3}$

$b^{3+1}=\frac{24\times 2}{3}$

$b^{4} = 16\\b=\sqrt[4]{16} \\b=2$

Put the b value in equation 2

$a=\frac{3}{2}\times 2$

$a=3$

Put the a and b value in equation 1

$y=3(2)^{x}$

So, the exponential function that passes through the points $(-1,\frac{3}{2})$ and $(3,24))$ are $y=3(2)^{x}$ .
