A circle has the equation (x-2)^2 +y^2 =5. What are the coordinates of the circle's center?

1 answer:

3 0

The circle with center (h, k) and radius r has equation
.. (x -h)^2 +(y -k)^2 = r^2

You have
.. h = 2
.. k = 0
.. r = √5

The center is (h, k) = (2, 0).

Given the parent function f(x)= log10^x and g(x)= 5x-2, what is f(x) • g(x)?

olchik [2.2K]

Answer:

$5x \log_{10}(x)-2 \log_{10}(x)$

(If that closed circle is an open circle, please let me know because that means something totally different)

Step-by-step explanation:

I think you are given:

$f(x)=\log_{10}(x) \text{ and } g(x)=5x-2$

and that you are asked to find:

$f(x) \cdot g(x)$

That operation means multiplication. (Let me know if is an open circle because that means something difference).

$f(x) \cdot g(x)$

$(\log_{10}(x) \cdot (5x-2)$

Distribute:

$\log_{10}(x)(5x)-\log_{10}(x)(2)$

Reorder a little (commutative property):

$5x \log_{10}(x)-2 \log_{10}(x)$

There are 16 sixth graders and 24 seventh graders attending a play. The teachers want to have the same number of students in eac

IRINA_888 [86]

8 students can be in a row.

If the same amount of students must be in each row across the grades, determine their greatest common factor. That would be 8 (8*2=16, 8*3=24). Any more than that, and the rows are uneven. There can be a max of 8 people in a row (2 rows for 6th grade, and 3 rows for 7th)

Hope it helps! I can explain further if needed
