In the diagram, AC is a diameter of the circle with center 0. If m ZACB = 50°, what is ZBAC?

Snowcat [4.5K]

Answer:

40degrees

Step-by-step explanation:

Find the diagram attached

Since the triangle ina semi circle is a right angle, hence <B = 90degrees

Also frm the diagram

<A + <B + <C = 180

<A + 90 + 50 = 180

<A + 140 = 180

<A = 180 - 140

<A = 40degrees

Hence the measure if m<BAC is 40degrees

Answer:

$7.5 plus $65 per hour

Step-by-step explanation:

We are trying to find the minimum she can make in one day. The minimum amount of hours she can work is 1, so find y when x=1:

y=7.5x+65

y=7.5(1)+65

y=7.5+65

Suppose f(x) = 1/4 over the range a ≤ x ≤ b, and suppose P(X > 4) = 1/2.

Anettt [7]

Answer:

a=2

b=6

Step-by-step explanation:

Assuming a uniform distribution and that a ≤ x ≤ b, if f(x) = 1/4, then:

$f(x) =\frac{1}{4}=\frac{1}{b-a}\\b-a = 4$

If P(X > 4) = 1/2, then:

$\frac{1}{2} = 1-(\frac{x-a}{b-a})=1-(\frac{4-a}{4})\\a-4+4 =\frac{1}{2}*4\\ a=2\\b=4+a\\b=6$

The values for a and b are, respectively, 2 and 6.

Part 1: Use the information provided to write the standard form equation of each circle. Please show the work.

dusya [7]

Answer:

1. (x + 2)² + (y - 9)² = 64

2. (x + 6)² + (y - 9/2)² = 100

3. (x - 15)² + (y + 10)² = 1

Step-by-step explanation:

Equation of a circle:

(x - h)² + (y - k)² = r²

1. Center: (-2, 9), Radius: 8

(x - (-2))² + (y - 9)² = 8²

(x + 2)² + (y - 9)² = 64

2. Center: (-6, 9/2), Radius: 10

(x - (-6))² + (y - (9/2))² = 10²

(x + 6)² + (y - 9/2)² = 100

3. Center: (15, -10), Radius: 1

(x - 15)² + (y - (-10))² = 1²

(x - 15)² + (y + 10)² = 1
