What is the measure of the central angle of a circle with radius 18 centimeters that intercepts a12π centimeters arc?

Answer:

D

Step-by-step explanation:

you can use the slope intercept form: y = mx + b.

y = y cooordinate

m = slope

x = x coordinate

b = y intercept

the y intercept is 4.

the point (1, 7) is what we're going to use.

so the new equation is

7 = m + 4 (it would be 1m, but i rewrote it to be mathmatically correct)

subtract 4 from both sides, you should have 3 = m.

the slope is 3

The function in the given graph obtained from the y and x-intercept is the option;

[tex]y = cot \left( \frac{3}{4} \cdot \left(x - \frac{\pi}{6} \right)\right)[/tex]

From the given graph, we have;

Similarly;

The above relationship corresponds with the following function;

[tex]y = cot \left( \frac{3}{4} \cdot \left(x - \frac{\pi}{6} \right)\right)[/tex]

The function graphed is therefore;

[tex]y = cot \left( \frac{3}{4} \cdot \left(x - \frac{\pi}{6} \right)\right)[/tex]

The diagonals of parallelogram RYUF each measure 24 units.

An equation is an expression that shows the relationship between two or more numbers and variables.

Diagonals of parallelogram are congruent and bisect each other.

Point N is the intersection point of the diagonals of parallelogram RYFU. Hence, RF is the diagonal and N is the midpoint:

2 * NF = RF

2(2x + 2) = 7x - 11

x = 5

RF = 7(5) - 11 = 24

The diagonals of parallelogram RYUF each measure 24 units.

The cyclist that will come to stop first when the brake is applied, is the cyclist with lesser mass which is Cyclist B because of its lesser inertia.

The law of inertia states that an object at rest or uniform motion in a straight line will continue in that path unless acted upon by an external force.

Inertia depends on mass of the object, the more massive an object is, the more reluctant it will be to stop and vice versa.

Thus, the cyclist that will come to stop first when the brake is applied, is the cyclist with lesser mass which is Cyclist B because of its lesser inertia.

Explanation

The first five months Paul paid  and in the next seven months he paid 24.

Discounts are defined as lowered prices or the sale of an item for less than it would typically cost. The fundamental formula for calculating a discount is to multiply the original price by the given percentage rate in decimal form. We must deduct the discount from the original price to determine the item's sale price. A discount is an amount that is subtracted from the regular price of an item.

Paul represent his plan in the form of equation:

[tex]5 x+7(x+8.50)=245.50[/tex]

Where x  is an amount for the first [tex]5[/tex] months that is paid by Paul after the discount and [tex](x+8.50)[/tex]  is an amount for the next [tex]7[/tex] month after discount.

[tex]&\Rightarrow \quad 5 x+7 x+59.50=245.50 \\&\Rightarrow \quad 12 x=186 \\&\Rightarrow \quad x=\frac{186}{12} \\&\Rightarrow \quad x=15.50\end{aligned}[/tex]

For the next 7 month:

[tex](x+8.50)=(15.50+8.50)=\$ 24[/tex]

Therefore, The first [tex]5[/tex] months Paul paid $ 15.50, and in the next [tex]7[/tex] months he paid $ 24.

The height of the cone is 4√2  inches.

The circumference of the base of each cone will be the arc length of one of the sectors  

= 2 [tex]\pi[/tex] (6)  / 3  

=  4 [tex]\pi[/tex]  inches

So, the radius, r, of each cone (in inches) is given  by :

4pi  =  2 [tex]\pi[/tex] * r

4  = 2r

2  = r  

Using the Pythagorean Theorem, the cone height, h, is given by :

h  = √[ slant height^2  - radius^2 ]  

=  √ [ 6^2  - 2^2 ]

= √32  

=  4√2  inches

Answer:

Step-by-step explanation:

Making 10 chairs would take Marjorie and Blaine 21 hours and 40 minutes.

The total time it takes Marjorie and Blaine to perform their respective tasks in building a chair is multiplied by 10 chairs, respectively.  This time is known as their speed.

The resulting figures are summed to get the total time.

The total time it takes Marjorie to build a chair is 15 hours (1.5 hours x 10)

The total time it takes Baline to sew cushions per chair is 400 minutes (40 x 10) or 6 hours and 40 minutes.

Therefore, the total time to build 10 chairs is 21 hours, 40 minutes (15 hours + 6 hours and 40 minutes).

The coordinates of the vertices of the translated triangle are A'(x, y) = (1, 8), B'(x, y) = (2, 6) and C'(x, y) = (- 1, 6).

Graphically speaking, triangles can be generated by knowing its three vertices. In this question we must apply a kind of rigid transformation known as translation, whose formula is:

P'(x, y) = P(x, y) + T(x, y)     (1)

Where:

If we know that A(x, y) = (3, 4), B(x, y) = (4, 2), C(x, y) = (1, 2) and T(x, y) = (-2, 4), then the new coordinates are:

A'(x, y) = (3, 4) + (- 2, 4)

A'(x, y) = (1, 8)

B'(x, y) = (4, 2) + (- 2, 4)

B'(x, y) = (2, 6)

C'(x, y) = (1, 2) + (- 2, 4)

C'(x, y) = (- 1, 6)

The statement presents typing mistakes, correct form is:

Translate the triangle with the vector <- 2, 4>, then enter the new coordinates:
