Answer:

15/17

Step-by-step explanation:

Cosine is equal to adjacent/hypotenuse. Since we don't have the hypotenuse in this case, we need to solve for it.

15^2+8^2=c^2

c=17

We get 17 for the hypotonuse.

Plug it into the equation adjacent/hypotenuse and you get 15/17

Answer:

D. 4(s + 3) & (s + 3) + (s + 3) + (s + 3) + (s + 3)

Step-by-step explanation:

We know this is a square (which is a polygon, which requires at least 3 sides), so A & B are out. C is also out because of the first expression. All 4 sides are s + 3; what the first expression on C is saying is we're adding a 5th side of 3 to 4 sides with length s. That leaves D as our answer. Bonus: Another expression that could work for this is 4s + 12 (which is both of D's expressions simplified.).

Answer:

151

Step-by-step explanation:

So you have to start by finding the total number of degrees inside the shape. The shape has 5 sides.

So using this formula:

(n-2) * 180

(5-2) * 180

= 540 degrees inside the shape

Then solve for x.

5x +2 + 10x - 3 + 8x -19 + 13x - 31 + 7x -11 = 540

43x -62 = 540

43x = 602

x = 14

Plug in for S.

4ab

Step-by-step explanation:

4(-3b)(+a)+8ab÷2a×4a

4(-3ab)+8ab÷2a×4a

-12ab+8ab÷2a×4a

-12ab+4b×4a

-12ab+16ab

16ab-12ab = 4ab

Answer/Step-by-step explanation:

First create a range for the number line. Label the number line. Then plot the minimum, lower quartile, median, upper quartile, and maximum values in this order. Draw a box from the lower quartile to the upper quartile, the line in the middle will go at the median. Now draw the line from the minimum & maximum values to the box.

Answer:

105 cm^2

Step-by-step explanation:

perimeter of the pentagon = 3 x 5 = 15 cm

lateral area of the prism = perimeter x height = 15 x 6 = 90 cm^2

lateral area of the pyramid = (slant height x perimeter)/2 = (2x15)/2 = 15 cm^2

total lateral area = 90 + 15 = 105 cm^2

Answer:

They are the same

Step-by-step explanation:

We are to check if (-5 + -3 ) =( -5 - +3)​

First you must know that the product of a positive and a negative n=sign will result in a negative sign i.e. + * - = -

Applying this in question;

(-5 + -3 )

= -5 - 3

= -8

similarly

( -5 - +3)​

= -5 - 3

= -8

Since both values are the same hence, (-5 + -3 ) =( -5 - +3)​

Answer: 2(12 × 8)

Step-by-step explanation:

The area of the rug will be gotten by multiplying the length by its width. This will be:

= 12 foot × 8 foot

= 96feet²

Since the area of the room is twice the area of the rug, the equation you will use to solve for x will be:

= 2(12 × 8)

= 2(96)

= 192feet²

Answer:

b = -5 and c = -4

Step-by-step explanation:

The common ratio here is r = 20/(-5), or -4, and the first term, a(1), is -5.  Thus, the explicit formula is

a(n) = a(1)*r^(n -1)    (must use parentheses, as shown)

and so we have a(n) = -5*(-4)^(n - 1).  b = -5 and c = -4

Answer:

B. The rate at which the balloon is rising.

Step-by-step explanation:

Mathematically speaking, the slope of the line represents the change in dependent variable (Height) divided by the change in independent variable (Time). According to the graph, a postive change in time leads to a positive change in height, meaning that slope is positive. Physically speaking, the slope represents the rate of change at which the height of the ballon is rising.

Hence, correct answer is B.

Answer:

0.841 (equivalent to 84.1%

Step-by-step explanation:

Chances are that your calculator has several different probability distribution functions built in.  Here we need the function    normal(

Typing that into a calculator, as follows, returns a decimal fraction which also represents the percentage of the time that a randomly selected class member scored above 79:

normalcdf(79, 1000, 84, 5) = 0.841 (equivalent to 84.1%)

Answer:

slope is undefined

Step-by-step explanation:

If the line was horizontal it would be 0 but this is verticle

Answer:

Undefined

Step-by-step explanation:

There's really no equation to this as it is a vertical line.

if it was horizontal it would be 0

but since it is a vertical line you can't really calculate meaning the answer is just undefined.

The graph of the function is the set of all points (x,y) in the plane that satisfies the equation y=f(x) .

The y value of a point where a vertical line intersects a graph represents an output for that input x value.
