Answer:

3.9 and -3.3

Step-by-step explanation:

1) cot 70=x/12

Cot 70=[opposite side]/[adyacent side]=x/12

The option 1 is correct

2) cot 70=12/x

Cot 70=[opposite side]/[adyacent side]=x/12

The option 2 is not correct

3)sec 20=x/12

Sec 20 =1/cos20

Cos 20==[opposite side]/[hypotenuse]=12/z

1/(1/cos20)-------> 1/(12/z)------> z/12

The option 3 is not correct

 
4) sec 20=12/x

Sec 20 =1/cos20

Cos 20==[opposite side]/[hypotenuse]=12/z

1/(1/cos20)-------> 1/(12/z)------> z/12

The option 4 is not correct

Answer:

A:  cot 70 degrees = x/12

Answer:

x + 3 + x

Step-by-step explanation:

3x :

This is a product of two terms, where x is any variable.

3 + x :

This is sum of two terms,where x is any variable.

x^3 :

This expresses x to the power of three. It can also be written as  (x times x times x ). Thus it is the product of three terms, where x is any variable.

x + 3 + x :

This is the sum of three terms, where x is any variable.

Thus answer is x + 3 + x

Final answer:

The surface area of a rectangular prism increases by four times when each of the dimensions is doubled because surface area scales in proportion to the square of the linear dimensions.

Explanation:

When the dimensions of a rectangular prism are doubled, the surface area of the prism increases by a factor of four. This is because the surface area is proportional to the square of the linear dimensions. If the length, width, and height of the prism are doubled, the new surface area (A') compared to the original surface area (A) is calculated as follows:

A' = 2l × 2w + 2l × 2h + 2w × 2h

A' = 4(lw + lh + wh)

A' = 4A

Thus, if each dimension is doubled, the surface area increases by four times.

The mean weight of five complete computer stations is 167.2 pounds.

The weights of four of the computer stations are 158.4 pounds, 162.8 pounds, 165 pounds, and 178.2 pounds.

We have to determine the weight of fifth computer station.

Let the weight of fifth computer station be 'x' pounds.

Mean is calculated by sum of all the observations divided by the total number of observations.

So, [tex] \frac{158.4+162.8+165+178.2+x}{5}=167.2 [/tex]

[tex] \frac{664.4+x}{5}=167.2 [/tex]

[tex] {664.4+x}=167.2 \times 5 [/tex]

[tex] {664.4+x}=836 [/tex]

x= 171.6 pounds

The weight of fifth computer station is 171.6 pounds.

To find the weight of the fifth computer station, subtract the sum of the weights of the four given stations from the mean weight.

The mean weight of five complete computer stations is 167.2 pounds. To find the weight of the fifth computer station, we can calculate the sum of the weights of all five stations and then subtract the sum of the weights of the four given stations. The weight of the fifth station can be found by subtracting the sum of the weights of the four given stations from the mean weight.

Sum of the weights of all five stations = 5 * 167.2 pounds

Sum of the weights of the four given stations = 158.4 pounds + 162.8 pounds + 165 pounds + 178.2 pounds

Weight of the fifth station = Sum of the weights of all five stations - Sum of the weights of the four given stations

late but i need points

Step-by-step explanation:

Answer:  The correct options are

(A) ML ∥ NO,

(C) LO ≅ MN.

Step-by-step explanation:  Given that in quadrilateral LMNO, LO ∥ MN.

We are to select the correct additional information that would be sufficient along with the given information to conclude that LMNO is a parallelogram.

PARALLELOGRAM:  A parallelogram is a quadrilateral if ine of the following conditions are satisfied:

(i) Two pairs of opposite sides parallel

or

(ii) one pair of opposite sides parallel and congruent.

The given condition is

LO ∥ MN.

So, the other additional sufficient condition will be

either the other pair of opposite sides parallel, i.e., ML ∥ NO,

or

the same pair of parallel sides are congruent, i.e,  LO ≅ MN.

Thus, the correct statements are ML ∥ NO and  LO ≅ MN.

Option (A) and (C) are correct.

Answer:

a and c

Step-by-step explanation:

Answer:

Option A. (0, -2)

Step-by-step explanation:

In the given graph coordinates of point A are (2, 0).

Now this point is rotated by -90° about the origin, that means rotation has been done clockwise by 90°.

Now after rotation this point A will lie on the negative side of the y-axis and the new coordinates become (0, -2).

Therefore, option A. (0, -2) is the correct option.

Final answer:

To find the equation of a circle, use the formula (x - h)² + (y - k)² = r², where (h,k) is the center of the circle and r is its radius. You apply this knowledge to other circular calculations, such as the angular velocity or the position and velocity of a moving point on the perimeter of the circle.

Explanation:

Finding the Equation of a Circle

To find the equation of a circle, you need to know the circle's radius (r) and the coordinates of its center (h,k). The general form of the equation is (x - h)² + (y - k)² = r². The values of h and k are the x and y coordinates of the center of the circle, respectively. If you recall the formula for the circumference of a circle, which is 2πr, and the area, which is πr², you can see that these both incorporate the radius of the circle in their calculations, similar to how the radius is used in the equation of the circle. When given certain dimensions or related motion problems, you can substitute known values into the equation to solve for the unknowns.

For example, if a circle has a radius of 5 units and its center is at the point (3,4), the equation would be (x - 3)² + (y - 4)² = 25. To find equations related to circular motion, like in the scenario of a student on a merry-go-round, knowing the radius also allows for determining the angular velocity and the velocity of a shadow or any point moving in circular motion.

The GCF of the given expression is:

                          [tex]5x^2y[/tex]

The GCF ( greatest common factor ) is the greatest divisor which divides all the terms completely.

Here we have the expression as:

[tex]10x^4y^3-5x^3y^2+20x^2y[/tex]

Here we see that the factors of the first term are:

[tex]10x^4y^3=2\times 5\times x\times x\times x\times x\times y\times y\times y[/tex]

The factor of the second term is:

[tex]-5x^3y^2=-1\times 5\times x\times x\times x\times y\times y[/tex]

and the factor of the third term is:

[tex]20x^2y=2\times 2\times 5\times x\times x\times y[/tex]

i.e. the factor which is common to all the three terms are:

[tex]5\times x\times x\times y=5x^2y[/tex]

Hence, the GCF is:   [tex]5x^2y[/tex]

Answer:

The measure of the smallest angle is 27°

Step-by-step explanation:

The triangle has angles with measure ratio 8:3:9, so the sizes of the angles are going to change depends on the ratio.

Let’s name the common value as “α”.

Basing on the angle-sum property, we already know that the sum of the angle in a triangle is 180°.

The measure of each one are:

8α, 3α, 9α

The sum of these is 180°.

Then,

8α + 3α + 9α = 180°

Let’s sum similar values:

20α =180°

α= 180°/20

α= 9

Replacing values, we going to find the measure of each angle:

8(9) = 72°

3(9) = 27°

9(9) = 81°

The measure of the smallest angle is 27°
