4 0

the second 3  (from the left) is in the hundreds place so we look at the  1st 7 (from the left) to determine how to round

since 7 is 5 or greater, we round the 3 to a 4

3400

Choice D

Factor 125x3 + 343y3
Annette [7]

Answer:

(5x + 7y)(25x² - 35xy + 49y²)

Step-by-step explanation:

125x³ + 343y³ ← is a sum of cubes and factors in general as

a³ + b³ = (a + b)(a² - ab + b² )

125x³ = (5x)³ ⇒ a = 5x

343y³ = (7y)³ ⇒ b = 7y

125x³ + 343y³

= (5x + 7y)((5x)² - (5x × 7y) + (7y)²)

= (5x + 7y)(25x² - 35xy + 49y²) ← in factored form

What is the equation of a sine function with an amplitude of 2 and a period of 4
antiseptic1488 [7]

Answer: C

Step-by-step explanation:

For this problem, we need to know the standard form of a sine function and the meaning of each part.

Standard form: y=asin[b(x-h)]+k

a=amplitude

b=period

h=phase shift

k=vertical replacement/shifting

Now that we know the standard form and the components, we know that we can forget about k and plug in 0 for h. This would leave us with y=asin[b(x)]. We know that the amplitude is 2, therefore, a=2. To find the period, you divide 2π by the given period. \frac{2\pi }{b} =\frac{2\pi }{4\pi } =\frac{2}{4} =\frac{1}{2}, therefore, b=1/2.

y=asin[b(x)]             [plug in a=2]

y=2sin[b(x)]             [plug in b=1/2]

y=2sin(\frac{1}{2}x)

Therefore, C is the correct answer.
