Answer:

hypotenuse = 8[tex]\sqrt{3}[/tex] , leg = 12

Step-by-step explanation:

Using the cosine and tangent ratios in the right triangle and the exact values

cos60° = [tex]\frac{1}{2}[/tex] , tan60° = [tex]\sqrt{3}[/tex] , then

cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{4\sqrt{3} }{hypotenuse}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

hypotenuse = 4[tex]\sqrt{2}[/tex] × 2 = 8[tex]\sqrt{2}[/tex]

---------------------------------------------

tan60° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{opposite}{4\sqrt{3} }[/tex] = [tex]\sqrt{3}[/tex] ( multiply both sides by 4[tex]\sqrt{3}[/tex] )

opposite = 4[tex]\sqrt{3}[/tex] × [tex]\sqrt{3}[/tex] = 12

Answer:

Lengths are 8√3 and 12

Step-by-step explanation:

» From trigonometric ratios, using our angle as 60°

[tex]{ \tt \cos( \theta) = \frac{adjacent}{hypotenuse} } \\ \\ { \tt{ \cos( 60 \degree) = \frac{4 \sqrt{3} }{hypotenuse} }} \\ \\ { \tt{hypotenuse = \frac{4 \sqrt{3} }{ \cos(60 \degree) } }} \\ \\ { \tt{hypotenuse = \frac{4 \sqrt{3} }{0.5} }} \\ \\ { \boxed{ \tt{hypotenuse = 8 \sqrt{3} }}}[/tex]

» Using 30° as our angle:

[tex]{ \tt{ \tan( \theta) = \frac{opposite}{adjacent} }} \\ \\ { \tt{ \tan(30 \degree) = \frac{4 \sqrt{3} }{adjacent} }} \\ \\ { \tt{adjacent = \frac{4 \sqrt{3} }{ \frac{1}{ \sqrt{3} } } }} \\ \\ { \tt{adjacent = \frac{(4 \sqrt{3} ) \times ( \sqrt{3}) }{1} }} \\ \\ { \tt{adjacent = 12}}[/tex]

Hi!

Given:

[tex]\frac{4}{5} *\frac{1}{4}[/tex]

First, multiply the numerators.

[tex]4*1=4[/tex]

Second, multiply the denominators.

[tex]5*4=20[/tex]

Now we have:

[tex]\frac{4}{20}[/tex]

Last, simplify. 20 and 4 can both be divided by 4.

[tex]\frac{4/4}{20/4} =\frac{1}{5}[/tex]

Your answer is [tex]\frac{1}{5}[/tex]

Answer: 7.69

Step-by-step explanation:

3.04+w=10.73

W+3.04=10.73

W+3.04-3.04=10.73-3.04

Subtract 3.04 from both sides

W=7.69

Using correlation coefficients, it is found that the -0.63 correlation between number of absences and final exam score means that there is a strong negative correlation between number of absences and final exam score.

It is an index that measures correlation between two variables, assuming values between -1 and 1.

If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.

If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.

In this problem, the correlation is of -0.63, hence:

It means that that there is a strong negative correlation between number of absences and final exam score.

The perimeter is equal to 14x + 8 but it is also equal to 2a + 2b, so

14x + 8 = 2(4x - 4) + 2b

14x + 8 = 8x - 8 + 2b

Let's move 2b to the other side of the equation, we get:

14x + 8 - 2b = 8x - 8

Now, let's move 14x + 8 to the other side too to find what -2b is equal to

-2b = 8x - 14x + 8 - 8

Gonna simplify:

-2b = -6x

Now, let's multiply both sides with -1 to find what 2b is equal to

-2b * -1 = -6x * -1

2b = 6x

Now, we know that 2*b is equal to 6x, but we need to find what side b is equal to, so we gonna divide 6x by two to get what b is equal to

2b = 6x

b = 3x

Side b is equal to 3x
