Step-by-step explanation:

a^2 cancels out a^5 remaining a^3 denominator

b2 cancels b4 = b2 numerator

c3 cancels out c8 = c5 remaining denominator

Calculate the unit rate for Machine A and Machine B. Determine which is the greater rate.

Damm [24]

Answer:

Machine B

Step-by-step explanation:

Since, Machine A covers $\frac{5}{8}$ square feet in $\frac{1}{4}$ hours,

Rate at which the Machine A is covering = $\frac{\frac{5}{8}}{\frac{1}{4}}$

= $\frac{5}{8}\times \frac{4}{1}$

= 2.5 square feet per hour

Machine B covers $\frac{2}{3}$ square feet in $\frac{1}{5}$ hours,

Rate at which the Machine B is covering = $\frac{\frac{2}{3}}{\frac{1}{5}}$

= $\frac{2}{3}\times \frac{5}{1}$

= $\frac{10}{3}$

= 3.33 square feet per hour

Therefore, Rate of Machine B is greater.

What are the possible rational zeros of f(x) = x4 + 2x3 − 3x2 − 4x + 20? (1 point)

Montano1993 [528]

The possible rational zeros of polynomial function $f(x) = x^4 + 2x^3 - 3x^2-4x + 20$ could be only among the divisors of the free term of this polynomial function.

The free term is 20 and the divisors of 20 are:

$\pm 1, \pm 2, \pm 4, \pm 5, \pm 10, \pm 20.$
