G(x) = x - 4

g(f(x)) = f(x) - 4 =

f(x) = e^x

g(x) = e^x - 4

Find the equation of a circle with a center at (7,2) and a point on the circle at (2,5)?

monitta

Answer:

$(x-7)^2+(y-2)^2=34$

Step-by-step explanation:

We want to find the equation of a circle with a center at (7, 2) and a point on the circle at (2, 5).

First, recall that the equation of a circle is given by:

$(x-h)^2+(y-k)^2=r^2$

Where (h, k) is the center and r is the radius.

Since our center is at (7, 2), h = 7 and k = 2. Substitute:

$(x-7)^2+(y-2)^2=r^2$

Next, the since a point on the circle is (2, 5), y = 5 when x = 2. Substitute:

$(2-7)^2+(5-2)^2=r^2$

Solve for r:

$(-5)^2+(3)^2=r^2$

Simplify. Thus:

$25+9=r^2$

Finally, add:

$r^2=34$

We don't need to take the square root of both sides, as we will have the square it again anyways.

Therefore, our equation is:

$(x-7)^2+(y-2)^2=34$

A farmer market has 7/9 bushel of plums when it opens in the morning.By noon ,1/3of the plums are left .How many ,plums in bushe

FromTheMoon [43]

Answer:

farmers market sold 4/9 plums in bushel

Step-by-step explanation:

We know that at the beginning of the day we have 7/9 of a bushel of plums and that after a while there are 1/3 of a bushel of plums, so to calculate how many were sold we have to subtract the bushel of plums that were left from the initial ones

7/9 - 1/3

if we want to do this subtraction we have to find a fraction equivalent to 1/3 that can be subtracted from 7/9

1/3 = (1 * 3) / (3 * 3) = 3/9

now we are just the top and leave the denominator the same as before

7/9 - 3/9 = 4/9
