You can answer that based on the absolute value of both numbers. So, if absolute value of the positive number is greater than that of the negative one, you will have a positive result. In the opposite situation, it would turn into a negative result. Finally, if both absolute values are equal, the sum is zero.

A=. B= 2.6 c=6.2 using Pythagorean Theron what is a?
Kryger [21]
Hello!
So you will use the Pythagorean Theron equation which is Asquare + bsquare=C square
Plug in what you are given to find the missing piece

A square+ (2.6)square= (6.2) square
Asquare+ 6.76= 38.44
(Subtract 6.76to both sides to isolate A)
Asquare= 31.68
(Take the square root of both sides to find out what A is)
A=5.628

. 7 prizes are to be distributed between 3 people with a guarantee that each person gets at least one prize. Find the number of
ANEK [815]

Answer:

Total number of ways to distribute the prize = 2187

3^{7}= 2187

Step-by-step explanation:

Given:

Number of prizes = 7

Number of peoples = 3

We need to find the total number of ways to distribute the prize.

Solution:

From the above statement, 7 prizes are to be distributed between 3 people, wherein each person gets at least one prize.

Each prize is to be distributed among three persons. When the first prize is to be awarded, one of the three is chosen to win the prize. When the second prize is to be awarded, there are again three choices.

So, total number of distribution of the prizes is given as:

3\times 3 \times 3\times 3\times 3\times 3\times 3=3^{7}

3^{7}= 2187

Therefore, total number of ways to distribute the prizes = 2187

Based on the family the graph below belongs to, which equation could represent the graph?
tatuchka [14]

Answer: y=-0.6x^3- 1

Step-by-step explanation:

In the graph, first we must see the points where the line intersects the axis.

We can see that it goes throug the point (0, -1)

Now, of the given options the only two that are 0 when x is -1, are:

f1(x) =y = 0.6*x^2 - 1

f2(x) =y = -0.6x^3 - 1

We also can see that for all the positive values of x, y has a negative value, so let's value bot functions in x = 2, and see what happens.

f1(2) = 0.6*4 - 1 = 1.4

f2(2) = -0.6*8 - 1 = -5.8

so the correct option is

y=-0.6x^3- 1

The diameter of a cone is 34 ft. the height is 16 ft what is the volume in cubic ft?
Ilia_Sergeevich [38]

Answer:

4842.24 cubic feet

Step-by-step explanation:

Use the formula for the volume of a cone, V = \pir²\frac{h}{3}

The diameter of the cone is 34 ft, so the radius is 17 ft.

Plug in the radius and height into the formula, and solve for the volume:

V = \pir²\frac{h}{3}

V = \pi(17)²\frac{16}{3}

V = \pi(289)\frac{16}{3}

V = 4842.24

So, the volume of the cone is 4842.24 cubic feet
