Find geometric mean between 2 and 8​

Mathematics
1 answer:
tester [92]3 years ago
3 0

Answer:  4

===================================

Rule: The geometric mean of two numbers x and y is sqrt(x*y)

In this case, x = 2 and y = 8

So we have the geometric mean equal to sqrt(2*8) = sqrt(16) = 4

If you wanted to find the geometric mean of three values, then you'll multiply the numbers and take a cube root. If you had four values, then you multiply and apply a fourth root. And so on.

6) Suppose that $5000 is deposited into an account that earns 3.5%
pantera1 [17]

Answer:

the future value is $5,750.01

Step-by-step explanation:

The computation of the future value is shown below;

As we know that

Future value = Present value × (1 + rate of interest)^number of years

= $5,000 × (1 + 0.035 ÷ 12)^4 × 12

= $5,000 × (1 + 0.2916%)^48

= $5,750.01

Hence, the future value is $5,750.01

The city is planning to add a fishpond to a neighborhood park the figure below is a scale drawing of the fishpond it's scale is
notsponge [240]
I saw the figure of the fishpond. It composed of a rectangle and a circle. The circle is cut into two and each half is attached to the width of the rectangle making an oblong shaped fishpond.

Length of the rectangle: 2.5 inch
Width of the rectangle and diameter of the circle: 1 inch

1/2 inch equals 15 feet.

2.5 inches = 75 feet
1 inch = 30 feet

Area of a rectangle = 75 ft * 30 ft = 2,250 ft²
Area of a circle = 3.14 * (15ft)² = 3.14 * 225ft² = 706.50 ft²

Total Area = 2,250 ft² + 706.50 ft² = 2,956.50 ft²

Can someone please explain the Pythagorean theorem to me?
Leona [35]

Answer:

Pythagoras theorem is is a mathematical law that states that the sum of squares of the lengths of the two short sides of the right triangle is equal to the square of the length of the hypotenuse.

Step-by-step explanation:

The hypotenuse is the side opposite to the right angle and so the equation for finding the hypotenuse would be:

a^2+^b^2=c^2

Carlos buys a game for $7.89 and some batteries for $5.49. He pays with a $20 bill. What is the best estimate of how much change
Molodets [167]

Given:

Carlos buys a game for $7.89 and some batteries for $5.49. He pays with a $20 bill.

To find:

The best estimate of the amount of change he should get.

Solution:

First we need to approximate the data values.

\$7.89\approx \$8.00

\$5.49\approx \$5.50

Now, the total cost of game and batteries is

\$8.00+\$5.50=\$13.50

He pays with a $20 bill.

Change=\$20-\$13.50

Change=\$6.50

Therefore, the estimated amount of change is $6.50.
