4z^3 + 5z^2 + z
Well that would be it... not much can be done considering the exponents of the variable :)

Volume of cylinder, write the term in pie

gladu [14]

Answer:

vol of cylinder = per. of base x height + 2 (area of base)

area of base = pi x r^2

4pi = pi r^2

4=r^2

r=2

per of base = 2 x pi x r

2xpix2=4pi (same as area cause 2x2 and 2^2 is the same thing)

4pi + 2(4pi)

4pi + 8pi

12pi = volume

hope that answers your question

What is the slope of a line perpendicular to the line whose equation is 4x+5y=35. Fully simplify your answer.

grin007 [14]

Answer:

The slope a line perpendicular to the line whose equation is 4x+5y=35, is $\frac{5}{4}$ .

Step-by-step explanation:

1. Solve the given equation for y.

$4x+5y=35\\\\5y=35-4x\\\\\frac{5y}{5} =\frac{35}{5} -\frac{4x}{5} \\\\y =7 -\frac{4x}{5}\\\\y = -\frac{4}{5}x+7$

2. Identify the slope.

The slope of a linear equation is always the number x is being multiplied for. Hence, the value of this equation is $-\frac{4}{5}$ .

3. Find the slope of the perpendicular line.

The slope of a perpendicular line is always the multiplicative and addition reciprocal of the initial function. This means that you will have to invert and fracction, and add the inverse sign before it. Let's do it by parts:

a) Find the multiplicative reciprocal (invert the fraction).

$-\frac{5}{4}$

b) Put the opposite sign before the fraction.

$+\frac{5}{4}$

4. Express a result.

The slope a line perpendicular to the line whose equation is 4x+5y=35, is $\frac{5}{4}$ .

Answer:

28 cubs

Step-by-step explanation:

Since one and a half bear produces one and a half cub, then 6 bears will produce 6 cubs in one and a half days.

We need to find 7 days, though but we have the rate for six bears for 1.5 days which 6 bears one a half day.

What is the rate for a day?

6/1.5 =

6 bears produce 4 cubs a day.

Now just do 4 x 7

4 x 7 = 28

Therefore, 6 bears produce 28 cubs in 7 days.
