help me please and explain it to me on why, I dont understand how. thank you!!​

Answer:

2.14 cm^3

Step-by-step explanation:

V = 4/3 pi r^3

V = 4/3 pi 0.512

V = 2.14

Using this formula, you just plug in your current values into a calculator and out comes the answer!

[tex]\frac{4}{3}[/tex]πr³

[tex]\frac{4}{3}[/tex]π(0.512)

^ (do 0.8³, which equals 0.512)

Step-by-step explanation:

6689x 6689

There are 2 terms multiplied together and they are identical

a*a = a^2

6689x 6689 = (6689)^2

Answer:

Angle A

Step-by-step explanation:

Angle A is the opposite angle to the longest side of the triangle.

Because the angle is larger, the side opposite of it should be long enough to connect to the two other sides.

If you add the whole numbers first it's 11 and then you add the decimals .5 is also .50. so .50+.25=.75

Answer: amplitude = 6.5

Step-by-step explanation:

The amplitude of a function is the maximum displacement from the from a fixed point or from the origin.

From the graph, you take the initial position of the object from the broken red line which is equal to 3.3 at the Y axis.

The peak or the maximum value = 9.8

Amplitude = 9.8 - 3.3 = 6.5

The maximum displacement is at Y axis

Answer:

0.00000008

Step-by-step explanation:

The given value is 8.03 X 10^-8, which is already in scientific notation. None of the provided alternatives exactly match the given value. The closest number to the given value is 9.71 X 10^-8.

The given value is 8.03 X 10^-8. This is already in scientific notation, where a number is represented as a decimal number between 1.0 and 10.0, multiplied by a power of 10. Therefore, it is equivalent to itself. If you would look for the equivalent among the options you have, none of them would match exactly the given value. The number that comes closest to your value from those given is 9.71 X 10^-8, but remember, these two are not exactly the same.

Step-by-step explanation:

Secant-Secant Formula:  

(whole secant) x (external part) =         (whole secant) x (external part)

Answer:

sin O = √85/11,  csc O = 11/√85

cos O = 6/11, sec O = 11/6

tan O = √85/6, cot = 6/√85.

Step-by-step explanation:

cos = adjacent / hypotenuse = 6/11, so the opposite side to angle O

= √(11^2 - 6^2)

= √85.

csc O = 1/sin O

sec O = 1/cos O

cot O = 1/tan O.

Answer:

x = 8

DBC =  32

Step-by-step explanation:

The sum of the two smaller angles is the larger angle

23+4x = 55

Subtract 23 from each side

23+4x-23 =55-23

4x = 32

Divide each side by 4

4x/4 = 32/4

x = 8

Then we want to find DBC = 4x = 4*8 = 32

Answer:

Step-by-step explanation:

form triangle

In order for the points to form a triangle, the sum of the lengths of any two sides must be greater than the length of the third side. In this case, 5 + 6 = 11 > 2, 5 + 2 = 7 > 6, and 6 + 2 = 8 > 5. Therefore, the points form a triangle.

Answer:

[tex] \sigma^2 = 3^2 \frac{10-1}{10}= 8.10[/tex]

Step-by-step explanation:

For this case we have a sample of n =10 and we have the following statistics:

[tex]\bar X = 37.3 , s= 3[/tex]

And we want to estimate the population variance. We need to remember that the population variance is given by this formula:

[tex]\sigma^2 =\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n}[/tex]

And the sample variance is given by:

[tex] s^2 =\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}[/tex]

And we can find a formula for the population variance in terms of the sample deviation like this:

[tex] \sigma^2 = s^2 \frac{n-1}{n}[/tex]

And replacing we got:

[tex] \sigma^2 = 3^2 \frac{10-1}{10}= 8.10[/tex]

Answer:

1296 different outcomes

Step-by-step explanation:

Each cube has 6 possible values (from 1 to 6), and for each additional cube rolled, we have 6 more possible values, and the final number of different outcomes is the product of all the number of possible values for each cube.

So, if we roll the cube four times, the total number of different outcomes is:

6 * 6 * 6 * 6 = 1296

We have 1296 different outcomes from rolling the six sided cube four times.

Answer:

Length = 14 inches

Width = 3 inches

Step-by-step explanation:

length * width = area

(x + 8 ) (x - 3) = 42

Use FOIL method

x*x  - x*3 + 8*x - 8*3 = 42

x² -3x + 8x - 24 = 42

x² + 5x - 24 - 42 = 0

x² + 5x - 66 = 0

Sum = 5

Product  = 66

Factors = 11 , (-6)

x²  + 5x -66 = 0

x² + 11x - 6x - 6*11 =0

x(x + 11) - 6(x + 11) = 0

(x + 11) (x -6) = 0

x + 11 is ignored because length and width will not have negative value.

x - 6 = 0

x = 6

Length = x + 8 = 6 + 8 = 14 inches

Width = x - 3 = 6 - 3 = 3 inches

Answer:

Let us say the domain in the first case, has the numbers. And the co-domain has the students, .

Now for a relation to be a function, the input should have exactly one output, which is true in this case because each number is associated (picked up by) with only one student.

The second condition is that no element in the domain should be left without an output. This is taken care by the equal number of students and the cards. 25 cards and 25 students. And they pick exactly one card. So all the cards get picked.

Note that this function is one-one and onto in the sense that each input has different outputs and no element in the co domain is left without an image in the domain. Since this is an one-one onto function inverse should exist. If the inverse exists, then the domain and co domain can be interchanged. i.e., Students become the domain and the cards co-domain, exactly like Mario claimed. So, both are correct!
