Find the area of the composite figure below.

Answer:

a = 45 degrees

Step-by-step explanation:

Since both angles are a, they are equal to each other

Also, we know that the right angle means it measures 90 degrees

So, (180-90)/2 = a

a = 45 degrees

Answer:

4239 cubic feet

Step-by-step explanation:

V=[tex]\pi[/tex][tex]r^{2} *h[/tex]

V=3.14*225*6

V=3.14*1350

V=4239

Answer:

B.   x < -4  and x > 3

Step-by-step explanation:

Factor and set = to 0

[tex]x^{2} + x - 12\\( x + 4)(x - 3)[/tex] = 0

x = - 4  or x = 3     I call these critical values

The two numbers would divide a number line into 3 intervals.  Pick a value in one of the intervals and put it in the original expression.  If it makes the function positive, then all the values in that interval make the function positive.  If the value you picked makes the function negative, then the values in the other intervals will make the function negative.  Let's pick the value of 0 and substitute it into the function

We get [tex]0^{2}[/tex] + 0 - 12 = -12 which is not positive.  Therefore, all the values between -4 and 3 will make the function negative.  So, the values less than -4 or greater than 3 will make the function positive.  Therefore, B is the correct answer.

Another way to do this problem is to graph the function and see where the graph is above the x-axis.  But, sometimes it is not easy to graph the function.

The solution will be the intersection points thus options A (1,-3) and B (-2,0) will be correct.

The graph is a geometrical representation of a function and can be plotted by taking x's and y's corresponding values within the interval.

For example plot of y = x³ ,y = sinx.

The solution will be the intersection points of both functions.

At the intersection point,

x² - 4 = -x - 2

x² + x - 2 = 0

x² + 2x - x - 2 = 0

x(x + 2) - (x + 2) = 0

(x - 1)(x + 2) = 0

x = 1,-2

At x = 1

y = -1 - 2 = -3 so first intersection is (1,-3)

At x = -2

y = -(-2) - 2 = 0 so second intersection is (-2,0)

Hence "The solution of the given system of equations is (1,-3) and (-2,0)".

Answer:

B

Step-by-step explanation:

x- intercept = 2  .So, Coordinate(2 , 0)

y-intercept = 8 . So, Coordinate (0, 8)

[tex]Slope = \frac{8-0}{0-2}\\\\=\frac{8}{-2}\\\\=-4[/tex]

Slope y-intercept form: y = mx + b  {Here, b is y-intercept}

y = -4x + 8

Answer:

x = -5/3

Step-by-step explanation:

2(3x + 2) = 2x - 1 + x

2 × 3x + 2 × 2 = 2x + x - 1

6x + 4 = 3x - 1

3x = -5

x = -5/3

Answer:

w = 5

Step-by-step explanation:

Answer: 4cm

Step-by-step explanation:

The area of a parallelogram is calculated by multiplying the height by the length:

Area = Height * length

Assume the length is x, substituting values would make the formula:

16 = 4 * x

4x = 16

x = 16/4

x = 4 cm

its - 5 why becase look at the question if im wrong sorry

its - 5

Answer:

5

Step-by-step explanation:

Plug in each number into the equation to its corresponding variable

So 9+6/3

Add the top numbers 9+6=15

now you have 15/3

Simplify 15/3

Answer:

41/2

Step-by-step explanation:

2x - 2(9) = 23

2x - 18 = 23

    +18   +18

2x = 41

/2    /2

x = 41/2

$200

Step-by-step explanation:

I just took away the tens and ones from the 2 numbers, so you have 900 and 700, subtract both of those and you get 200, BAM! hope this helped it's my first time doin thiS :)

19.625cm squared because you have to divide the diameter by 2 to get the radius.

Area of circle = pi times radius times radius

= 3.14 times 2.5 times 2.5

= 19.625cm squared

Answer: Fred's Slope

Step-by-step explanation:

Comparing the slope were are looking at the numerator or y of the slope to find which one takes you the highest compared to the others.

Start with Sam who has a slope of 2/11 or rise 2 run 11 which is pretty flat so sam is out

Fred and Anne both have a slope that is a whole number so we're lloking for the bigger number which would be Fred

Anne's slope is 4.75

sams slope is 2/11

and fred’s is 5
