Answer:

y = (1/2) cos (x)

Step-by-step explanation:

It has the same period as cos x but only goes half as high and half as low. Normalyy, cos(x) goes up to 1 and down to -1.

Answer:

6.9

Step-by-step explanation:

Arc Length Formula: 2rπdata/360

First find data:

In this case, data is the length of arc AB

Arc AB is the central angle: 165 degrees

Substitute radius and data into the formula

2(2.40)(165)π/360

This form(792/360π) is not acceptable since the question is asking for the answer in decimal form. Multiply pi.

Make sure to use the pi symbol, not 3.14.

792/360π

6.91 to the nearest tenth is 6.9

Hope this helps!

-2 is the biggest number because in the negatives the bigger number us always the smaller one.

Answer:

In the form of (x,y) there are 2 solutions:

(-3,4)

(-24/5, -7/5)

Step-by-step explanation:

First isolate one of the letters (for me I'm using the y of equation 2 because it's easier to solve)

[tex]y-3x=13\\y=13+3x[/tex]

Now that we have y isolated, substitute y in equation 1 with the equation we got previously (y=13+3x)

[tex]x^2+(13+3x)^2=25[/tex]

Now simplify:

[tex]x^2+(13+3x)^2=25\\x^2+9x^2+78x+169=25\\10x^2+78x+169=25[/tex]

Now turn the equation into ax^2+bx+c=0 form by transferring 25 to the other side of the equation:

[tex]10x^2+78x+169=25\\10x^2+78x+169-25=0\\10x^2+78x+144=0[/tex]

Using the quadratic formula we will have the 2 following values:

[tex]x=-3[/tex]

[tex]x=-\frac{24}{5}[/tex]

Substitute the following values into any equation you want (this time I'll pick equation 2 again since its the easiest to solve)

[tex]y-3x=13\\y-3(-3)=13\\y-(-9)=13\\y+9=13\\y=13-9\\y=4[/tex]

[tex]y-3x=13\\y-3(-\frac{24}{5})=13\\y-(-\frac{72}{5})=13\\y+\frac{72}{5}=13\\y=13-\frac{72}{5}\\y=-\frac{7}{5}[/tex]

Answer:

[tex]2\ln 3+\ln 8=\ln 72[/tex]

Step-by-step explanation:

Logarithms

Some properties of the logarithms are:

[tex]\ln xy = \ln x+\ln y[/tex]

[tex]\ln x^n=n\ln x[/tex]

We have:

[tex]2\ln 3+\ln 8[/tex]

Applying the exponent property:

[tex]2\ln 3+\ln 8=\ln 3^2+\ln 8=\ln 9+\ln 8[/tex]

Applying the product property:

[tex]2\ln 3+\ln 8=\ln (9*8)=\ln 72[/tex]

[tex]\boxed{2\ln 3+\ln 8=\ln 72}[/tex]

Answer:

3579.6 [tex]ft^{3}[/tex]

Step-by-step explanation:

First, write out the equation used to find the volume of a cylinder and place the values in place of the variables. The equation is [tex]\pi[/tex][tex]r^{2}[/tex]*h where r is the radius and h is the height. When we place the values of the variables into the equation we get: [tex]\pi[/tex][tex]10^{2}[/tex]*11.4. Next, square 10 to get 100. This would give you 3.14*100*11.4. When you multiply this together you get 314 times 11.4 which gives you 3579.6 ft cubed.

I believe it's 3581.42 (if the answer needs be rounded to 2 decimal places.

Step-by-step explanation:

area of circle = r×r×π

area of circle × height = volume

10 × 10 × π = 314.16

314.16 × 11.4 = 3581.42

   2. | given (note this is a side) |

   3. | given |

   4. | definition of a midpoint (a midpoint bisects the line it is one because it is equidistant from the two endpoints; basically, the two pieces of a line bisected by a midpoint will always be equal) |

   5. | SSS Theorem (the two givens beside the midpoint were two sets of equal corresponding sides; since we have three sets of corresponding sides equal, the theorem used here is the SSS Theorem) |

Answer:

X=-4

Step-by-step explanation:

-2x + 4 = 12

so what you would do is subtract 4 from itself and 12

4 - 4 = 0

12 - 4 = 8

then we have-

-2x = 8

we then divide 2 from 2 and 8

2 divided by 2 = 0

2 divided by 8 = 4

so x = -4

Answer:

m=[tex]\frac{-1}{3}[/tex]

Step-by-step explanation:

Answer:

Im not good at math

Step-by-step explanation:

Answer:

a) P = 24.2 units

b) A = 13.9 square units

Step-by-step explanation:

Perimeter = [tex]\sqrt{10}[/tex]+[tex]\sqrt{10}[/tex] + 4[tex]\sqrt{5}[/tex] + 4[tex]\sqrt{5}[/tex]

P = 2[tex]\sqrt{10}[/tex] + 8[tex]\sqrt{5}[/tex] which is approx 24.2 units

To find area you must find the height which can be done using the Pythagorean Theorem (we can do this for the small triangle on the left):

([tex]\sqrt{5}[/tex]²) + h² = ([tex]\sqrt{10}[/tex]²)

5 + h² = 10

h² = 5

h = [tex]\sqrt{5}[/tex]

A = bh

A = [tex]\sqrt{5}[/tex] (4 + [tex]\sqrt{5}[/tex])

A = 4[tex]\sqrt{5}[/tex] + 5 which is approx 13.9 square units

Answer:

a. greater than 75 J

Step-by-step explanation:

Potential Energy at the top = mgh

Mass m = 2kg

g = 9.8m/s^2

height h  = 10m

Potential Energy at the top = 2 * 10 * 9.8

Potential Energy at the top = 196Joules

The object is not moving at the bottom, hence the KE of the body at the bottom is 0Joules

difference between the PE at the top and the KE at the bottom = 196 - 0 = 196Joules

Hence the difference between the PE at the top and the KE at the bottom is greater than 75Joules

Answer:

-30 5/6

Step-by-step explanation:

You are adding two negative numbers, so add their absolute values and make the answer negative.

-28 1/3 + (-2 1/2) =

= -(28 1/3 + 2 1/2)

We add the absolute values 28 1/3 and 2 1/2. We need a common denominator for the fractions. The LCD of 2 and 3 is 6.

= -(28 + 2 + 1/3 + 1/2)

= -(30 + 2/6 + 3/5)

= -(30 5/6)

= -30 5/6

the answer is 4 than me later
