To find the area of a circle you have to know the radius so to do that you’d divide 44 by 2 = 22 inches
22 inches = radius
Then multiply the radius by pi, let’s assume it 3.14
22 x 3.14 = 69
Then you multiply it by 2 bc the formula of an area of a circle is pi times the radius times 2
So, 69 x 2 = 138
So area of the table is 138 inches

Answer: 1521

Step-by-step explanation: use the equation pi times radius square. Your radius is always going to be half your diameter so you'll use 22 instead. Then plug that I'm and you should get 1520.53 rounded would be 1521.

Find the solution to the system of equations-2 + 2y = -4 3x + 3y = -18
AfilCa [17]

Answer:

\boxed{x = -2~~and~~ y = -4}

Step-by-step explanation:

-2x + 2y = -4 (times 3) -6x + 6y = -12

3x + 3y = -18 (times 2) 6x + 6y = -36

.

-6x + 6y = -12

<u>6x + 6y = -36 </u>+

12y = -48

y = \frac{-48}{12}

y = -4

.

Substitute the value of y to the one of equations

-2x + 2(-4) = -4

-2x - 8 = -4

-2x = -4 + 8

-2x = 4

x = \frac{4}{-2}

x = -2

Find an obtuse angle whose sine is<br> a) 0.25<br> b) 0.75<br> c) 0.875<br> d) 0.3465
swat32

Answer:

a) 165.52 degrees.

b)  131.41 degrees.

c)  118.96 degrees.

d)  159.73 degrees.

Step-by-step explanation:

The sine of an obtuse angle is positive as it is in the second quadrant.

a) Using a calculate the angle whose sine ( arcsin) is 0.25  = 14.478 degrees

so the obtuse angle  = 180 - 14.478 = 165.52 degrees to nearest hundredth

b) c) and d) are calculated in the same way.

Evaluate y = ex + 1 for the following values of x. Round to the nearest thousandth. x = −2, y ≈ x = 1, y ≈ x = 2, y ≈
soldier1979 [14.2K]
The equation is not clear whether it is y= e^{x+1} or y= e^{x} +1

for y= e^{x+1}

x=-2 ⇒ e^{-2+1}=0.37
x=1 ⇒ e^{-1+1} = e^{0}=1
e^{2+1}= e^{3}=20.10

for y= e^{x}+1

x=-2⇒y=e^{-2}+1 =1.14
x=1⇒y= e^{1} +1=3.72
x=2⇒y= e^{2}+1=8.39

Hint: Most scientific calculators have the template of e^{( )} which you can use to work out the value of y
