Solve for x. Assume that lines are diameters?

Answer:

y=9x

Step-by-step explanation:

First let's find the slope of this.

To find the slop we can take two points.

(1,9) & (3,27)

27-9/ 3-1 (slope equation) = 18/2=9

The slope of the equation is 9.

Now let's use point-slope form to find the equation.

(1,9)

y-9=m(x-1) (substitute the x2 and y2 values for the coordinate values)

y-9=9(x-1) (substitute m for the slope)

y=9x-9+9

y=9x

Answer:

a) 24 degrees

b) 50 degrees

Step-by-step explanation:

part a : use sine-1

sine-1 = [tex]\frac{opposite}{hypotenuse}[/tex]

sine-1 = [tex]\frac{17}{42}[/tex]

sine-1 = 0.405

missing angle = 23.89

round to the nearest degree = 23.89 = 24

part b : use cosine-1

cos-1 = [tex]\frac{adjacent}{hypotenuse}[/tex]

cos-1 = [tex]\frac{16}{25}[/tex]

cos-1 = 0.64

missing angle = 50.208

round to the nearest degree = 50.208 = 50

20)452.39ft²

Step-by-step explanation:

Step-by-step explanation:

To find the diameter of a circle, you multiply the radius (the radius is the distance from the outside of the circle to the middle) by 2.

Ex: the first one has 6m as the radius. So you would multiply the 6 by 2. Which would be 12.

The radius is half of the diameter. So for number 8, the answer would be 2.

Answer:

C = 101

E = 46

Step-by-step explanation:

79 + 134 = 213

180 - 79 = 101 (C+F has to equal 180)

79 + 134 + 101 = 314

360 - 314 = 49 (trapezoids have a total degree of 360)

The measure of angles are ∠C = 101°, ∠E = 46°, ∠J = 83°, ∠L =97°, and ∠M = 97°.

It is given in the picture that measures the angles of a trapezoid.

It is required to find the other angles.

It is defined as the quadrilateral having four sides in which two sides are parallel to each other it is a 2-dimensional geometry.

We have a trapezoid CDEF in which ∠D = 134° and ∠CFE = 79°

We know in trapezoid:

∠C+∠F = 180° and

∠D+∠E = 180°

For ∠C = 180° - ∠F ⇒ 180° - 79° ⇒ 101°

For ∠E = 180° - ∠E  ⇒ 180° - 134° ⇒46°

We have another trapezoid JKLM in which ∠K = 83°

We know in isosceles trpezoid:

∠K = ∠J = 83° and

∠L = ∠M

∠L = 180° - ∠K ⇒ 180° - 83°  ⇒ 97° ⇒ ∠M

Thus, the measure of angles are ∠C = 101°, ∠E = 46°, ∠J = 83°, ∠L =97°, and ∠M = 97°.

Answer:

Step-by-step explanation:

add them and add 1

An expression equivalent to m + m + m + m as a sum of two terms is 4m.

An expression is combination of variables, numbers and operators.

The given expression is:

m + m + m + m

Equivalent expressions are expressions that work the same even though they look different.

We can combine like terms to simplify the expression:

m + m = 2m

Now plug in the expression of m+m in the given expression.

So the expression becomes:

m + m + m + m = 2m + 2m

Now we have expressed the given expression as a sum of two terms, which are both 2m:

2m + 2m = 4m

Therefore, an expression equivalent to m + m + m + m as a sum of two terms is 4m.

Answer:

x = 25

Step-by-step explanation:

2x + 70 = 120      {Subtract 70 from both sides}

        2x = 120 -70

        2x = 50      {divide both sides by 2}

Answer:

56πx² + 36πx + 6π square inches

Step-by-step explanation:

The radius of a cylindrical gift box is ​(3x+1​) inches. The height of the gift box is twice the radius. What is the surface area of the​ cylinder? Write your answer as a polynomial in standard form.

The surface area of a cylinder is given as:

2πr(r + h)

The radius of a cylindrical gift box is ​(3x+1​) inches.

The height of the gift box is twice the radius = 2(3x + 1) inches

= 6x + 2 inches

The surface area of the cylinder is:

= 2 × π × 3x + 1( 3x + 1 + 6x + 2) square inches

= 2 × π × 3x + 1(9x + 3) square inches

= 2π × 3x + 1(9x + 3) square inches

= 6πx + 2π( 9x + 3) square inches

= 6πx (9x + 3) + 2π( 9x + 3) square inches

= 56πx² + 18πx + 18πx + 6π square inches

= 56πx² + 36πx + 6π square inches

The surface area of the​ cylinder is 56πx² + 36πx + 6π square inches

x= 128*

Step-by-step explanation:

180*-52*=128*

Answer:

x = 128

Step-by-step explanation:

well we know that for a polygon, the interior angles always add up to 360.

One angle is 52, and since the other two have squares it means that they are a perfect 90 degree angle. add those up to get 232, and then subtract 232 from 180 to get 128
