Answer:

1)54° 2)5π 3)a=3π 4)b 5)(x – 11)^2+ (y – 6)^2=36 6)center=(7,-6) radius=5 8)b

Step-by-step explanation:

1- π radians = 180°

so 3π/10=(3*180)/10=54°

2- in order to find arc length we need to find the ratio of the angles then make that equal to the ratio of the arc length to the perimeter:

x=arc length of HN

150/360=x/2πr

5/12=x/2*6π

5/12=x/12π

12*5π=12x

x=5π

3- in order to find the area of the shaded region we have to take the ratio of the angles and make that equal to the ratio of the area of the shaded region to the whole area:

a=area of the shaded region

30/360=a/πr^2

1/12=a/36π

36π=12a

a=3π

4- a slice of a 16 inch pizza has an area of 64π/8=8π

two slices of a 10 inch pizza has an area of 2*(25π/8)= 6.25π

therefore we would be more satisfied with a slice of an 16 inch pizza, which is b.

5- the formula for the equation of a circle is: (x – h)^2+ (y – k)2 = r2

h=x-coordinate of the center point k= y-coordinate of the center r=radius

in this question the center is (11,6) so h=11, k=6 and the radius is 6 so r=6

we plug in

(x – 11)^2+ (y – 6)^2=36

6- h=7 k=-6 so the center is (7,-6)

radius=5

8- center=(1,3) and radius=2

so the graph that corresponds to these values is b

Answer:

  x = -6

Step-by-step explanation:

The curve is symmetrical about the vertical line through the minimum point. That minimum is 6 grid squares left of the y-axis, so the equation is ...

  x = -6

Answer:

Step-by-step explanation:

"100" or any constant at the end of the equation is r² (radius squared). So, the radius is 10.

the center of the circle is (-6, 2)

the equation template of a circle is (x -h)² + (y - k)² = c

(h,k) is the center of the cirlce.

Answer:6

Step-by-step explanation:

Answer:

We can use the Pythagorean theorem and properties of sines, cosines, and tangents to solve the triangle, that is, to find unknown parts in terms of known parts.

Step-by-step explanation:

Pythagorean theorem:   a2 + b2 = c2.

Sines:   sin A = a/c, sin B = b/c.

Cosines:   cos A = b/c, cos B = a/c.

Tangents:   tan A = a/b, tan B = b/a.

Answer: Smaller

Step-by-step explanation:

Multiplying a number by 1.25 increases it by a quarter

Multiplying a number by 0.75 decreases it by a quarter

1.25 / 0.75 = 0.9375

Thus, increasing something by a quarter then decreasing it by a quarter, you are effectively multiplying that number by 0.9375, which is less than 1, so the number will decrease.

The total distance around the track is 332.2 meters

The complete question is in the attached image

The given parameters are:

Radius, r = 25 m

Length, l = 87.6 m

Start by calculating the circumference of the two semi-circular ends using:

[tex]C = 2\pi r[/tex]

So, we have:

C = 2* 3.14 * 25

Evaluate

C = 157

The total distance around the track is then calculated as:

Total = 2l + C

This gives

Total = 2 * 87.6 + 157

Evaluate

Total = 332.2

Hence, the total distance around the track is 332.2 meters

Answer:

Q= (5,4)

Step-by-step explanation:

The x value went up by 4 units and the y value up by 6 units from the first point to the midpoint. Since the midpoint is equal distance from both points, we know it will go up by the same amounts for Q.

Answer:

[tex]a_{n}[/tex] = 20 - 9n

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 2 - 11 = - 7 - 2 = - 9

This indicates the sequence is arithmetic with nth term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 11 and d = - 9 , then

[tex]a_{n}[/tex] = 11 - 9(n - 1) = 11 - 9n + 9 = 20 - 9n
