Step-by-step explanation:

Using the Pythagorean Theorem, it is found that the length of the diagonal of the square shown below is given by:

F. [tex]h = 7\sqrt{2}[/tex]

The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:

[tex]h^2 = l_1^2 + l_2^2[/tex]

In this problem, the diagonal is the hypotenuse, while the legs are the sides of [tex]l_1 = l_2 = 7[/tex], hence:

[tex]h^2 = l_1^2 + l_2^2[/tex]

[tex]h^2 = 7^2 + 7^2[/tex]

[tex]h^2 = 2 \times 49[/tex]

[tex]h = \sqrt{2 \times 49}[/tex]

[tex]h = 7\sqrt{2}[/tex]

Hence option F is correct.

[tex]y = Acos(Bx - C) + D[/tex]

The A is amplitude, B is to find the period, C is the phase shift and D is the vertical shift

Amplitude = [tex]A = \frac{1}{7}[/tex]

Period = [tex]\frac{2\pi}{B} = \frac{2\pi}{8} = \frac{\pi}{4}[/tex]

Phase shift = [tex]C = - \frac{\pi}{6}[/tex]

Vertical shift = [tex]D = -5[/tex]

Answer:

y = - 4x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 4 and c = - 3 , thus

y = - 4x - 3 ← equation of line

Hii!

__________________________________________________________

Answer:

Below is all the info you need! ^^

Step-by-step explanation:

Do you remember the slope intercept formula?

y=mx+c is the formula, in which m denotes the slope and c denotes the y intercept.

Suppose we have the slope m and the y intercept c. What is the equation? y=mx+c.

Similarly, if we have the slope -4, and the y intercept -3, the equation is y=-4x+(-3), or y=-4x-3.

Answer:

y = 8x + 8

Step-by-step explanation:

The y-intercept is already given so we have our b = 8 so y = mx + b becomes y = mx + 8. Now we need to figure out the slope so looking at the chart I need to figure out what number when multiplied by the x value and added to b equals the y value. The answer is 8 because when we multiply it by 1 and add it to 8 we are left with 16, which supports the chart. The equation in slope intercept form is now y = 8x + 8

Answer:

height of water in the container is 3 cm.

Step-by-step explanation:

Given;

A sealed rectangular container, measuring 4 cm by 8 cm by 16 cm

the height of the container is 16 cm, when filled with water at 4 cm level from the top, thus, the height of water in the container is (16 cm - 4cm) = 12cm

Volume of water in the container when it is sitting on its smallest face = 4 cm x 8 cm x 12 cm = 384 cm³

Volume of water in the container when it is sitting on its largest face = 8 cm x 16 cm x h

where;

h is height of water in the container

384 = 8 x 16 x h

384 = 128h

h = 384 / 128

h = 3 cm

Therefore,  height of water in the container is 3 cm.

Answer:

B: 9d^8

Step-by-step explanation:

Simplify the expression using the rules of exponents.

This is a regular conditional expression because it is in the form "If P, then Q"

P = Maura is going to the library

Q = she is bringing her favorite binder

A biconditional is of the form "P if and only if Q"

The "if and only if" is the key phrase needed. It allows us to swap the positions of P and Q to say "Q if and only if P".

Answer: 3

Step-by-step explanation:

Mean simply means average. To calculate mean,we add together all the numbers given and divide them by the amount of numbers.

The Mean here will be:

= [8 +(-10) + 7 + 10 + (-3) + 6]/6

The mean is 3

Answer:

£2.20

Step-by-step explanation:

ok i don't know any thing about pounds i think those are pounds but i do know my math

2 x 1.40 = 2.80

if you gave the caster 5 pounds they would give you ? back

5 - 2.80 = 2.20

you would get 2.20 pounds in return

Answer:

£2.20 (Without paying taxes)

Step-by-step explanation:

First you multiply 1.4 x 2 to get 2.8

Then subtract that by 5 ( 5.0 - 2.8)

Finally from that you will have gotten the answer 2.2

Answer:

D

Step-by-step explanation:

You can ignore the power, since taking something to the power of one doesn't change the answer.

Anything to the 0 is going to be 1, so the answer is one over something.

The denominator is clearly going to be positive, regardless of what the symbol is.

With this in mind, it seems like the answer should be 1/9.
