Answer:

Radius of the circle is 4 and center (0, 10).

Step-by-step explanation:

Equation of the circle is given as x² + (y -10)² = 16

We have to find the radius and the center of the circle.

As we know the standard equation of the circle is (x-h)²+ (y-k)² = r²

Now we will compare the equation of the circle given with the standard form of the equation.

Our equation is (x -0)²+ (y - 10)² = 4²

Radius of the circle will be 4 and center will be (0, 10)

The center of the circle is at (0, 10). This is because they are the numbers being subtracted from the x and y values.

The rule is that you add 1/16 each time. You can see this if you find the common denominator (16):

1/16, 2/16, 3/16, 4/16, 5/16, 6/16

Marcus earns $8.40 per hour. He works for 26 hours each week, 48 weeks each year. If he earns over $10,000, then Marcus has to p

MAVERICK [17]

We have been given that Marcus works for 26 hours each week and 48 weeks each year.

Thus in a year he works for $26 \times 48 = 1248$ hours.

Now, we have been given that Marcus earns $8.40 per hour.

Therefore, in 1248 hours, he earns

$1248 \times 8.40\\
\\
=\$ 10483.2$

Marcus has to pay tax if he earns more than $10,000. Now we have calculated that he earns $ 10483.2 which is higher than $10,000.

Therefore, Marcus has to to pat tax.

a man casts a 3 feet long shadow. if the suns rays strike the ground 62°, what is the height of the man?

Romashka [77]

Answer:

h = 3*tan(62) where h is the height

Step-by-step explanation:

You basically have a right triangle. the standing man is the vertical line, the shadow is the horizontal line and the 62 degrees is the angle betweenthe horizontal line and the hypotenuse.

So, relative to the angle we have the adjacent angle and opposite. What uses those? Tangent. tan(x) = opp / adj

tan(62) = h/3

h = 3*tan(62) where h is the height

If f(x) = 1/3x+13, then f^-1(x) =??

Sergeeva-Olga [200]

Step-by-step explanation:

Given

f(x) = 1/3x + 13

f^-1(x) = ?

Now

Let y = f(x)

or y = 1/3x + 13

Interchanging the role of x and y

x = 1/3y + 13

x - 13 = 1/3y

y = x - 13

Therefore f^-1(x) = x - 13

Hope it will help you.
