Hey there! The correct answer is D.1 the reason is because the number of the data is plotted incorrectly.

Consider triangle MOP. This triangle is right triangle, because  m∠P=90°.

Since  m∠P=90°, m∠M=60°, then m∠O=180°-90°-60°=30°.

The leg opposite to the angle with measure 30° is half of the hypotenuse. Let the leg MP=x, then the hypotenuse MO=2x. By the Pythagorean theorem,

[tex]PO^2+MP^2=MO^2\Rightarrow PO^2=(2x)^2-x^2=4x^2-x^2=3x^2\Rightarrow PO=\sqrt{3}x.[/tex]

The perimeter of triangle MOP is

[tex]P_{MOP}=MO+PO+MP=x+2x+\sqrt{3}x=3x+\sqrt{3}x.[/tex]

Since [tex]P_{MOP}=12+4\sqrt{3},[/tex] then [tex]x=4.[/tex]

Answer: MP=4 units.

Answer:

mp=4 cuz in a 30-60-90 degree right triangle if the shorter leg is x, then the longer leg (po) is xsqrt3. Because the perimeter is 12+4sqrt3, that means the longer leg is probably 4sqrt3. because of this, then the shorter leg, mp is 4. Since the hypotenuse is equal to 2x, then it would be 2*4=8=PO.

You have to observe that [tex] x^4 [/tex] and 625 are both squares (of [tex] x^2 [/tex] and 25, respectively). So, you can use the "difference of square" pattern for factorization:

[tex] a^2-b^2 = (a+b)(a-b) [/tex]

to write

[tex] x^4 - 625 = (x^2+25)(x^2-25) [/tex]

Note that, again, [tex]x^2-25[/tex] is a difference of square:

[tex] x^2-25 = (x+5)(x-5) [/tex]

On the other hands, [tex] x^2+25 [/tex] admits no factorization, because it's a second-degree polynomial (thus a parabola) with no solutions.

So, the whole expression becomes

[tex] x^4 - 625 = (x^2+25)(x+5)(x-5) [/tex]

m = [tex]\frac{1}{2}[/tex],   (x₁ , y₁) = (-2, -4)

y - y₁ = m(x - x₁)

y -(-4) = [tex]\frac{1}{2}[/tex](x - (-2))

y + 4 = [tex]\frac{1}{2}[/tex](x +2)

y + 4 = [tex]\frac{1}{2}x[/tex] + 1

     y = [tex]\frac{1}{2}x[/tex] - 3

Answer: A

we know that

f(3) is the value of the function when x is equal to 3

so

For x=3

see in the graph

f(3)=6

see the attached figure

therefore

the answer is

f(3)=6

According to the graph in the problem, f(3) = 6

In the graph we have curve and line. we look out for domain of 3

The domain of 3 is the point on the graph where x axis is 3. At this point we trace to the graph and find the corresponding value on the y axis

This gives the solution of the graph

Step-by-step explanation:

(A) Bella's TV ratio of sides: 36"/27" = 1.333...

Lenny's: 52"/29.25" = 1.777...

Bella's and Lenny's TVs are NOT similar - their side ratios are different. Bella's is 4:3 while Lenny's is close to 16:9.

(B) Bella's TV has an exact ratio of 4:3 (36/27=4/3) and so is the older type.

Lenny's TV has a ratio of 52"/29.25". Divide both 52 and 29.25 by 3.25 to get 16/9, or 16:9. So Lenny's is the newer type.

[tex]\frac{w}{xy} = \frac{-6}{-3(4)} = \frac{-6}{-12} = \frac{1}{2}[/tex]

Answer: [tex]\frac{1}{2}[/tex]

The formula for 'w' in terms of the perimeter 'P' and length 'l' of the rectangle is w = (P - 2l)/2.

To solve for 'w' in the formula for the perimeter of a rectangle, P = 2(l + w), we need to isolate 'w' on one side of the equation.

P = 2(l + w)

First, distribute the 2 to both terms inside the parentheses:

P = 2l + 2w

Now, subtract 2l from both sides to move it to the other side of the equation:

P - 2l = 2w

Finally, divide both sides by 2 to solve for 'w':

w = (P - 2l)/2

Therefore, the formula for 'w' in terms of the perimeter 'P' and length 'l' of the rectangle is:

w = (P - 2l)/2

The slope is 1/3 ( the slope is the number with the variable x).

There is no other operation ( addition or subtraction) so the y- intercept is 0

For this case we have:

We define the following variable

x : Speed of the car in South direction

By definition, we know that:

[tex]Distance = Speed * Time[/tex]

For the car in north direction:

[tex]D1 = V1 * T1\\D1 = 50mph * 3h\\D1 = 150 miles[/tex]

For the car in south direction:

[tex]D2 = V2 * T2\\D2 = x * 3\\D2 = 3x[/tex]

The distance between both cars, after 3 hours, is:

[tex]D = D1 + D2[/tex]

So, we have:

[tex]345 = 150 + 3x[/tex]

Clearing x;

[tex]3x = 345-150\\3x = 195\\x = 65[/tex]

Thus, the speed of the car in the south direction is [tex]x = 65mph[/tex]

The product of the given expression of a fraction is -1/2.

It is required to find the product.

A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator. In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator. In a proper fraction, the numerator is less than the denominator.

Angle (3x+31)° and angle (2x-6)° are supplementary angles. Then the value of the variable x is 31°.

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

Angle (3x+31)° and angle (2x-6)° are supplementary angles. Then we have

(3x + 31)° + (2x - 6)° = 180°

5x + 25° = 180°

5x = 155°

x = 31°

Then the value of the variable x is 31°.

The value of  x equals 31°.

The value of (x) can be found by solving the equation formed by the two angles in the given question:

Given angles:

Linear pair property:  The sum of the measures of two angles forming a linear pair is (180°).

Now,

Set up the equation: (3x + 31) + (2x - 6) = 180

=>  (3x + 2x) + (31 - 6) = 180

=> 5x + 25 = 180

Solve for (x):  5x = 155 =>  x = 31

Therefore, the value of (x) is 31°.

Answer:

z-score will be:  7.741....  and it will be unusual.

Step-by-step explanation:

Human body temperatures have a mean of 98.20 degrees Fahrenheit and a standard deviation of 0.62 degrees Fahrenheit.

So here,  [tex]\mu= 98.20[/tex] and [tex]\sigma= 0.62[/tex]

Formula for z-score is:   [tex]z= \frac{X-\mu}{\sigma}[/tex]

Thus, the z-score for 103.00 degrees Fahrenheit will be.......

[tex]z(X=103.00)= \frac{103.00-98.20}{0.62}=7.741...[/tex]

As, here the z-score is more than 2 standard deviations above the mean, so 103.00 degrees Fahrenheit is unusual for human body temperature.

If we want to verify that g ( x ) is the inverse of f ( x ) we have to show that:

( f ° g ) = ( g ° f )

f ( g ( x ) )=  3 · ( 1/3 x ) = x

g ( f ( x ) ) = 1/3 · ( 3 x ) = x

Answer:

C ) 1/3 ( 3 x )

Answer:

Step-by-step explanation:

To verify if two functions are inverse, we have to find the composition of such functions, that is:

[tex]f(g(x))[/tex]; which results must be the variable [tex]x[/tex] to be inverse functions.

We know that: [tex]f(x)=3x;g(x)=\frac{1}{3}x[/tex].

Replacing on the composition:

[tex]f(g(x))=3(\frac{1}{3}x)=x[/tex]

Therefore, the expression that has to be used to verify that these functions are inverse is C.
