Answer:

The answer is 82 square feet

Step-by-step explanation:

An easy way to do this is to split it into two rectanlges. You can do 10*5 and 8*4 as the dimensions to the two rectangles or you can do 2*4 and 9*8.

I am going to do the first option.

The area of a rectangle is length times width.

Rectangle one can be the one with the dimensions 10 and 5 and the length and width.

Rectangle two can be the one with the dimensions 8 and 4 and the length and width.

Area of rectangle one = 50 feet^2

Area of rectangle two = 32 feet^2

Since we split a large irregular shape into two bits, we must add them together, which results in 82 feet^2.

Find the area of a semi circle with a diameter of 28cm
Alexandra [31]

since it has a diameter of 28, then its radius must be half that or 14.

\textit{area of a circle}\\\\ A=\pi r^2~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=14 \end{cases}\implies A=\pi (14)^2\implies A=196\pi ~\hfill \stackrel{\stackrel{semi-circle}{half~that}}{98\pi }

Help ASAP!!<br>Using the graphed function above, find the following
Alenkinab [10]

Answer:

Maximum: 1, Minimum: -3, Midline y = -1, Amplitude = 4, Period = \pi, Frequency \displaystyle =\frac{1}{\pi},  equation : f(x)=-4cos(2x)+1

Step-by-step explanation:

<u>Sinusoid Functions</u>

It refers to the oscillating functions like the sine or cosine which range from a minimum and maximum value periodically.

The graph shown can give us all the information we need to answer these questions:

Maximum: 1

Minimum: -3

The midline goes through the center value (mean) of the max and min values, i.e.

Equation of the midline:

\displaystyle y=\frac{1-3}{2}=-1

Amplitude is the difference between the maximum and minimum values

A=1-(-3)=4

The period is the time it takes to complete a cycle. We can see the minimum value is first reached at x=0 and next at x=\pi

Thus the period is

T=\pi

The frequency is the reciprocal of the period:

\displaystyle f=\frac{1}{T}=\frac{1}{\pi}

The angular frequency is

\displaystyle w=2\pi f=\frac{2\pi }{\pi}=2

The equation of the function is a negative cosine (since it starts at the minimum) or a shifted sine or cosine. We'll choose the negative cosine, knowing all the parameters:

f(x)=-4cos(2x)+1

How is the vertex related to the maximum or minimum of a parabola?
USPshnik [31]

Answer:

Vertical parabolas give an important piece of information: When the parabola opens up, the vertex is the lowest point on the graph — called the minimum, or min. When the parabola opens down, the vertex is the highest point on the graph — called the maximum, or max.

Natalija [7]

Answer:

  25

Step-by-step explanation:

Synthetic division shows the remainder to be 25-c. In order for that remainder to be zero, the value of c must be 25.
