An ordinary piece of copier paper has a dimension of 8.5 inches by 11 inches. Converting inches to feet:

8.5 in * (1 ft / 12 in) = 0.708 ft

11 in * (1 ft / 12 in) = 0.917 ft

Therefore the area is simply:

Area = 0.708 ft * 0.917 ft

Area = 0.65 ft^2

Solve for g. what is g equal to?

sweet [91]

Answer:

$\displaystyle g=\frac{4\pi^2l}{T^2}$

Step-by-step explanation:

Equation Solving

Given the equation

$\displaystyle l=\frac{gT^2}{4\pi^2}$

It's required to solve it for g. Let's swap sides of the equation:

$\displaystyle \frac{gT^2}{4\pi^2}=l$

Multiply by $4\pi^2$ to remove the denominator:

$\displaystyle gT^2=4\pi^2l$

Divide by $T^2$

$\boxed{\displaystyle g=\frac{4\pi^2l}{T^2}}$

F(x) = 8cos(2x) on (0,2π)

Leviafan [203]

Answer:

Step-by-step explanation:

First put the lower limit, i.e., x=0,

F(x)=8cos[2(0)]=8cos(0)=8(1)=8

;cos(0)=1

Now,put the upper limit of given interval, i.e., x = π,

F(x)=8cos[2(π)]=8cos(2π)=8(1)=8

;cos(2π)=1

Pierce draws a circle with a radius of 3 centimeters. Ginna draws a circle with a radius that is twice as long as the radius of

erastova [34]

Answer:

Circumference of the circle drawn by Ginna is twice the Circumference of the circle drawn by Pierce.

Step-by-step explanation:

Given:

Radius of the circle drawn by Pierce = 3 cm

We need to find circumference of gianna's circle compare with the circumference of Pierce's circle.

Solution:

Radius of the circle drawn by Pierce = 3 cm

so we will find the Circumference of circle drawn by Pierce.

Now we know that;

Circumference of the circle is given by 2 times π times radius of the circle.

framing in equation form we get;

Circumference of the circle drawn by Pierce = $2\pi\times 3=6\pi\ cm$

Now Given:

Ginna draws a circle with a radius that is twice as long as the radius of pierce's circle.

So we can say that;

radius of the circle drawn by Ginna is equal to 2 times radius of circle drawn.

so we can say that;

radius of the circle drawn by Ginna = $2\times3 = 6\ cm$

Circumference of the circle drawn by Ginna = $2\pi\times 6=12\pi\ cm$

Now we can see that;

Circumference of the circle drawn by Ginna is $12\pi \ cm$ while Circumference of the circle drawn by Pierce is $6\pi \ cm$

So we can say that;

Circumference of the circle drawn by Ginna is twice the Circumference of the circle drawn by Pierce.

Find the distance from point A(15, -21) to the line 5x +2y = 4

jarptica [38.1K]

The distance from a point to a line is
distance(ax+by+c=0,(x0,y0)) = abs(ax0+by0+c)/sqrt(a^2+b^2)
So first convert the formula for the line to standard form
5x+2y=4
5x+2y-4=0

a=5, b=2, c=-4, x0=15, y0=-21

abs(5*15+2*(-21)-4)/sqrt(5*5+2*2)
= abs(75-42-4)/sqrt(25+4)
= 29/sqrt(29)
= sqrt(29)
= 5.385165 (approximately)
