Remember
√(ab)=(√a)(√b)
and
√x²=x
so

note: x⁴=(x²)(x²)
and y³=(y²)(y)
√(18x⁴y³)=
(√18)(√x⁴)(√y³)=
(√9)(√2)(√x²)(√x²)(√y²)(√y)=
(3)(√2)(x)(x)(y)(√y)=
3x²y√(2y)

C is the answer

Answer:

The center (2, 2.5), radius $\sqrt{37}$ / 2

Step-by-step explanation:

The standard form of the equation of a circle is:

( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius

Rewrite the given equation in the standard form:

2x^2 + 2y^2 - 8x + 10y + 2 = 0
x^2 - 4x + y^2 + 5y = -1
x^2 - 4x + 2^2 + y^2 + 5y + (5/2)^2 = -1 + 4 + 25/4
(x - 2)^2 + (y + 2.5)^2 = 37/4

The center is:

(2, 2.5)

And radius is:

$\sqrt{37}$ / 2

Which set of ordered pairs could be generated by an exponential function ?

lawyer [7]

Answer:

The third choice is the correct answer

Step-by-step explanation:

The set of ordered pairs which could be generated by an exponential function is

$(1,\frac{1}{2}),(2,\frac{1}{4}),(3,\frac{1}{8}),(4,\frac{1}{16})$

If we examine the y-values of this set of ordered pairs, we can see that they have a common ratio of

$r=\frac{1}{4}\div \frac{1}{2}$

$r=\frac{1}{4}\times 2$

$r=\frac{1}{2}$

This makes it exponential.

Answer:

12.50h = 2500.75

Step-by-step explanation:

He earned $12.50 for 1 hour of work.

For 2 hours, he earned $12.50 × 2.

For 3 hours, he earned $12.50 × 3.

For h hours, he earned $12.50 × h which can be simply written as 12.50h

He earned altogether $2500.75, so 12.50h must equal 2500.75.

Answer: B 12.50h = 2500.75

A machine shop produces metal frames on two different machines. The average daily production on machine 1 is 300 frames, and the

statuscvo [17]

Answer:

The daily shop productivity is 480 frames

Step-by-step explanation:

The daily machine productivity refers to the TOTAL production made in a day.

The problem says that a shop produces metal on two different machines. It means that you must take into account the daily production of each one for finding the total production.

The first machine produces 300 frames in a day.

The second machine produces 180 frames in a day too.

So, if the first and the second machines are working together in a single day, the TOTAL daily production is the sum of the production of each one.

$production=300+180=480$

Thus, the daily shop productivity is 480 frames
