Answer:

192π^3

Step-by-step explanation:

the formula for calculating volume of a cylinder is πr^2h (r : radius, h : height)

π×4^2×12 = 192π^3

Find the indicated values, where g(t)=t^2-t and f(x)=1+x g(f(2)+3)

sleet_krkn [62]

Answer:

$g(f(2)+3)=30$

Step-by-step explanation:

We have the two functions:

$g(t)=t^2-t\text{ and } f(x)=1+x$

And we wish to find:

$g(f(2)+3)$

First, let’s find f(2) first. So, we will substitute 2 for x for f(x):

$f(2)=1+(2)=3$

Hence, we can now substitute 3 for f(2):

$g(f(2)+3)=g(3+3)=g(6)$

Now, we can find g(6). Substitute 6 for t for g(t):

$g(6)=(6)^2-(6)=36-6=30$

Therefore:

$g(f(2)+3)=30$

7. A sales girl is paid Rs 5,000 per month as salary and a 4 commission of % on total sales. If she receives Rs 5,192 at the end

kari74 [83]

Answer:

Sh 4800

Step-by-step explanation:

5192 - 5000 = 192 ( which is the total commission)

4% = 192

100%=? ( so we get the total sales)

100*192/4 = 4800 ( which is the total sales )

Answer:

14 ft

Step-by-step explanation:

Focus on the triangle, and temporarily neglect the 2 ft measurement at the top of the triangle. Then the 2 legs of the triangle have lengths h - 2 ft and 5 ft, and the hypotenuse is 13.

Applying the Pythagorean Theorem, we get:

13^2 = (h - 2)^2 + 5^2, or

169 = h^2 - 4h + 4 + 25, or

144 = h^2 - 4h + 4, or

140 = h^2 - 4h, or, finally,

h^2 - 4h - 140 = 0. We must find the value of h.

I graphed this function on a calculator and found that -10 is a zero. Thus, the function factors into (h + 10)(h - 14) = 0, or h = 14.

The total height of the piece of plywood is 14 ft.

Check this: does a right triangle with legs (14 - 2) and 5 have a hypotenuse of 13? Yes.

The teacher passed out math books.The length is 10 inches and the width is 8 inches.What is the perimeter of each book?

miv72 [106K]

Answer: The perimeter of each book is: " 36 in. " .

__________________________________________________

Step-by-step explanation:

__________________________________________________

Note that the given units are all in "inches (in.)" .

Use the formula for the "perimeter of a rectangle" ;

{which happens to work for a "square" as well;

since a "square" is a rectangle.}.

__________________________________________________

This is based on the assumption that the book is shaped like a

"rectangle" (or "square" —which is a rectangle).

__________________________________________________

The formula for the Perimeter of a rectangle is:

P = 2 L + 2 w ;

in which:

P = the perimeter of the rectangle;

for which we shall solve; [in "inches (in.)" ] ;

L = the length of the rectangle = 10 in. (given) ;

w = the width of the rectangle = 8 in. (given) .

___________________________________________________

Now, plug the given values for the "length (L)" and the "width (w)" ;

as follows:

___________________________________________________

P = (2 * 10 in.) + (2 * 8 in.) ;

P = (20 in.) + (16 in.) ;

P = 36 in.

___________________________________________________

Answer: The perimeter of each book is: " 36 in. " .

Hope this helps!
