\bf \stackrel{\textit{volume of a cylinder}}{V=\pi r^2 h}\qquad \qquad \stackrel{\textit{volume of a cone}}{V=\cfrac{\pi r^2 h}{3}}\\\\
-------------------------------\\\\
\stackrel{\textit{volume of this cylinder}}{\pi (4)^2(12)}~~+~~\stackrel{\textit{volume of this cone}}{\cfrac{\pi (4)^2(6)}{3}}
\\\\\\
192\pi ~+~32\pi \implies 224\pi

What is the slope of the line y = - 5/4x - 5 ?
Jobisdone [24]

Answer:

-5/4

Step-by-step explanation:

Slope is rise over run which means that the -5 will apply to your y values and the 4 will apply to your x values. This slope would have a point move down 5 units and to the right 4 units to get the location of the next point when going left to right. Because the slope contains a negative, the slope will be angled downward left to right. The negative only applies to the 5.

Use trigonometric expressions to build an equivalent trigonometric identity with the given expression: sec (x) tan (x) cos (x) c
Bess [88]

Answer:

sec (x)

Step-by-step explanation:

sec (x) tan (x) cos (x) csc (x) =

We know sec = 1/ cos

Tan = sin/cos

csc = 1/sin

Replacing into the expression

1/ cos (x) * sin(x)/ cos (x) * cos (x) * 1 / sin(x)

Canceling like terms

1/ cos (x)

sec(x)

Apply the distributive property to write an equivalent expression in factored form: 12s + 18r
Kryger [21]
The most simplified answer is the greatest factor being six. Divide both by six and six is on the outside of parentheses to be equivalent making the answer 6(2s+18r) or -6(-2s-18r) if you used negatives as I would jot down negative and positive

What is 8.545 kilograms rounded to the nearest hundredth?
ohaa [14]
8.545 rounded to the nearest hundredth is 8.55. I think so because the number in the hundredth place is 4, the number on the right of it is 5. 5 is equal to 5 so the 4 turns into 5
