Please help!! i don’t understand how to find mBOC

Mathematics
1 answer:
Arturiano [62]4 years ago
3 0

Answer:

m∠BOC = 60°

Step-by-step explanation:

m∠AOB and m∠BOC have to add up to m∠AOC.

Step 1: Define

m∠AOB = 7x + 30

m∠BOC = 9x + 42

m∠AOC = 104

Step 2: Set up

7x + 30 + 9x + 42 = 104

Step 3: Solve for <em>x</em>

<u>Combine like terms:</u> 16x + 72 = 104

<u>Subtract 72 on both sides:</u> 16x = 32

<u>Divide both sides by 16:</u> x = 2

Step 4: Find m∠BOC

m∠BOC = 9(2) + 42

m∠BOC = 18 + 42

m∠BOC = 60°

The rate of change will be positive and a point in the graph will be (1,250);
the function then would be y = 250x;
after 1 year she will owe USD 5,250;
she will have to make 33 payments.

How to form equation using slope and one point?
y - y1 = m(x - x1) is the equation of a straight line's point slope form, where m is the line's slope and (x1, y1) is the point through which the provided line passes.

Using slope-point equation, the equation for the payment can be taken as:
y-250 = [(500-250)/(2-1)]*(x-1)
y - 250 = 250*(x-1)
y = 250 + 250x - 250 = 250x;
Putting x = 12, for a year the amount paid is USD 3,000.
Amount she owes = USD (8250-3000) = USD 5,250;
Total amount to be paid (in USD) = 8250
Amount paid per month (in USD) = 250
Thus, number of payments required = 8250/250 = 33

Thus, the rate of change will be positive and a point in the graph will be (1,250); the function then would be y = 250x; after 1 year she will owe USD 5,250; she will have to make 33 payments.

Robin Cline is a computer analyst. Her annual salary is $52,789. What is her monthly salary? *
Helen [10]

Answer:

<h2>$43999.08 per month</h2>

Step-by-step explanation:

step one:

We can calculate her monthly salary by dividing her annual salary by 12

given that her annual salary is  $52,789

so we divide  $52,789 by 12,

step two:

Note: we are dividing by 12 because in a year we have 12months

so  $52,789/12

=$43999.08

step three:

from the division, we can see that in a month Robin Clines monthly salary is  

$43999.08 per month

If the endpoints of the diameter of a circle are (8, −6) and (4, −2), what is the standard form equation of the circle?
Gennadij [26K]
We do the midpoint formula to find the center of the circle to get the left side of the equation.

Midpoint = [(X₁ + X₂) / 2 , (Y₁ + Y₂) / 2] 

Now plug in:

[(8 + 4) / 2 , (- 6 - 2) / 2]
(12 / 2 , - 8 / 2)
(6, - 4)

The center of the circle is (6, -4)

Now we plug it into the equation of a circle:

(x - h)² + (y - k)² = r² where (h, k) is the center of the circle and r is the radius. 

(x - 6)² + (y + 4)² = r² is the left side of the equation. This will eliminate options A and C

Now we do the distance formula using the center and an endpoint to get the radius. The formula for distance is:

√((X₂ - X₁)² + (Y₂ - Y₁)²)

We plug in using either of the endpoints. 

√((4 - 6)² + (- 2 - (- 4))²)
√((-2)² + 2²)
√(4 + 4)
√8

√8 is your radius

(√8)² = 8

Your correct answer is (x - 6)² + (y + 4)² = 8, Option D

SOMEONE HELP
pantera1 [17]

Answer:

D

Step-by-step explanation:

Given y varies directly as x and z then the equation relating them is

y = kxz ← k is the constant of variation

To find k use the condition y = \frac{8}{3} when x = 1 and z = 4 , then

\frac{8}{3} = k × 1 × 4 = 4k ( divide both sides by 4 )

\frac{2}{3} = k

y = \frac{2}{3} xz ← equation of variation

When x = 6 and z = 3 , then

y = \frac{2}{3} × 6 × 3 = \frac{2}{3} × 18 = 2 × 6 = 12
