Answer:

y = 1 · 5^x

Step-by-step explanation:

Use the given values in the given formula and solve for 'a' and 'b'.

y = a·b^x

5 = a·b^1 . . . . . . for (x, y) = (1, 5)

125 = a·b^3 . . . . for (x, y) = (3, 125)

Divide the second equation by the first:

125/5 = (a·b^3)/(a·b^1)

25 = b^2 . . . simplify

5 = b . . . . . . . take the square root

Substituting into the first equation, we can find 'a':

5 = a·5

1 = a . . . . . . . divide by 5

Written in the given form, the equation is ...

y = 1 · 5^x

Find the length of side xx in simplest radical form with a rational denominator.

borishaifa [10]

Answer:

x = 3sqrt(2)/2

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse

The two legs are equal, x

x^2 + x^2 = 3^2

2x^2 = 9

Divide each side by 2

x^2 = 9/2

Take the square root of each side

sqrt(x^2) = sqrt(9/2)

x = sqrt(9)/ sqrt(2)

x = 3 / sqrt(2)

x = 3 sqrt(2) / sqrt(2)*sqrt(2)

x = 3sqrt(2)/2

A farmer sells 7.7 kilograms of apples and pears at the farmer's market.

vagabundo [1.1K]

Answer:

She sold 5.775 kilograms of pears at the farmer's market.

Step-by-step explanation:

Let's first determine the information that the question gives us, and what we need to find.

Given:

The farmer sold 7.7 kilograms of apples and pears

1/4 of the weight is apples

The rest of the weight is pears

Find:

Kilograms of pears that the farmer sold

Start by finding the fraction of the whole weight that was pears...

$1-\frac{1}{4}=\frac{4}{4}-\frac{1}{4}=\frac{3}{4}$

Now, find 3/4 of 7.7...

$\frac{3}{4}(7.7)=\frac{23.1}{4}=5.775\ kg$

She sold 5.775 kilograms of pears at the farmer's market.
