The area of the circle is 28 ft square.

The area of the triangle is 30 ft square.

Step-by-step explanation:

1) The area of the circle= π*r^2

where π= 3.14(default value) and "r" is the radius of the circle.

Here, Radius of the circle(r)= 3 ft

Area = 3.14*3*3

        = 28.26 ft sq.= 28 ft sq(rounded to the nearest whole number)

2) The triangle has the base= 10 feet and height= 6 feet

The Area of the triangle= 1/2(b)(h)

where "b" is the base and "h" is the height of the triangle.

Substitute b=10 and h=6 ,

Area of triangle= 1/2(10 ft)(6 ft)= 60/2= 30 feet sq.

Answer:

-39

Step-by-step explanation:

\left(-3\right)^3-\sqrt[3]{27}-4^3\left(\sqrt[3]{64}-\left(2\right)\left(2\right)\right)-\frac{\left(3\right)^3\left(2\right)}{6}

-27-3-64\left(4-4\right)-\frac{54}{6}

-27-3-\frac{54}{6}

-27-3-9

Which gives us -39.

Graph and Label the Points on the coordinate plane below
Lapatulllka [165]
In order to graph these, you need to understand the X and Y axis.

The X-Axis contains the first number in your ordered pair, and goes left, right (horizontally) for example the first ordered pair you have.

(2,5 1/2). To do this, move 2 spaces to the right on your X-axis. now go 5 and a half spaces up, and plot the point.


(-2 1/2, 0.5) For this one, you move 2 and a half spaces to the left on the X-axis, and half a space up. put a point there.


(3.5, -4 1/2) move 3 and a half spaces to the right on your X-axis, and go 4 and a half spaces down. put a point there.

let me know if you have questions! :)

What is the inverse of the function f(x) = 2x + 1?
Liula [17]

<em><u>Inverse</u></em><em><u> </u></em><em><u>Of</u></em><em><u> </u></em><em><u>Functions</u></em>

I use a certain way to find the inverse of a function.

Replace H(x) with y.

y=2x+1

Replace y and x.

x=2y+1

Find y.

x-1=2y

Divide both sides by two.

x-1/2=y

<em>The</em><em> </em><em>Answer</em><em> </em><em>Is</em>

<em>h^{ - 1} (x) =  \frac{x - 1}{2}</em>

Can u guys help me like I’m so lost rn
Komok [63]

Answer:

The answer is A because when you take both X and Y they are both negative so the only way to keep the answer negative would be to add them.

If you subtract one from the other it adds the opposite

If you multiply them the negatives cancel each other and the answer becomes positive

If you divide them the negatives cancel out and so again the answer would be positive

Step-by-step explanation:

When you add an negative number to another negative number your number stays negative
