the answer is 153.86 ft squared
= the formula for the area of a circle is A=πr2
= area = pi x radius squared
= the radius is 7 feet, square that to get 49
= multiply 49 by pi to get the area: 153.86 square feet
153.86 ft squared
Answer:
153.86 ft squared

As per given question we have provided that :
➟ Radius of circular pool = 7 feetWe need to find :
➟ Area of circular poolHere's the required formula :
[tex]{\dashrightarrow\sf{A = \pi {r}^{2}}}[/tex]
↝ A = Area ↝ π = 3.14 ↝ r = radiusSubstituting all the given values in the formula to find the area of circular pool :
[tex]{\dashrightarrow{\sf{Area = \pi {r}^{2}}}}[/tex]
[tex]{\dashrightarrow{\sf{Area = 3.14{(7)}^{2}}}}[/tex]
[tex]{\dashrightarrow{\sf{Area = 3.14{(7 \times 7)}}}}[/tex]

From a rectangular 5×13 piece of cardboard, four congruent squares with sides of length x are cut out, one at each corner. (See the accompanying figure.) The resulting crosslike piece is then folded to form a box. Answer the following.
a) Find the volume V of the box as a function of x.
b) Sketch the graph of y=V(x).
The Dimensions of box be:
L = 2.21406 ftD= 10.78594 ftH = 1.10703 ftVolume, V = 24.4366 ft³What is Volume of Cuboid?The volume of the cuboid is the measure of the space occupied within a cuboid. The cuboid is a three-dimensional shape that has length, breadth, and height.
a)Each side of the future box is
L = 5-2x ,D = 13-2x
and let the height of box is x
Then, volume of the box as function of x is:
V(x)= (5-2x)*(13-2x)*x
V(x)= (65-10x-26x +4[tex]x^{2}[/tex])*x
V(x)= 65x-36[tex]x^{2}[/tex]+4[tex]x^{3}[/tex]
Differentiate the above equation, we get
V'(x)= 65-72x+12[tex]x^{2}[/tex]
If V'(x) = 0, then
65-72x+12[tex]x^{2}[/tex]=0
[tex]x_{1,2} = (-b\pm \sqrt{ b^{2} - 4*a*c} ] /2a[/tex]
[tex]x_1[/tex]=4.89297
[tex]x_2[/tex]=1.10703
We will take x= 1.10703
Then the sides of the box are:
L = 5-2(1.10703) = 2.21406 ft
D = 13 - 2*x = 13 - 2x(1.10703)= 10.78594 ft
H = x = 1.10703 ft
Now, volume is
V = 2.21406*10.78594*1.10703 = 24.4366 ft³

if a fire ranger on a tower 150 ft spot a fire at an angle of 30-depression, how many feet away is the tower is from the fire.
By using trigonometric relations, we will see that the distance to the fire is .173.21 ft
How to find the distance to the fire?
Here we can compare this with a right triangle. We know that one angle on the right triangle is 30°, and the adjacent cathetus to that triangle is 150ft.
Now, we want to find the hypotenuse of said triangle, which is the distance to the fire.
So we can use the trigonometric relation:
cos(a) = (adjacent cathetus)/(hypotenuse).
Replacing what we know, we get:
cos(30°) = 150ft/hypotenuse
hypotenuse = 150ft/cos(30°) = 173.21 ft
So the distance to the fire is 173.21 ft

The speed that marina can run from the given parameters is; 4 miles per hour
How to Solve Algebraic Problems?Let x be Marina's speed running.
Marina's speed biking is x + 9.
Thus, the time she spent is calculated as;
19.5/(x + 9) = 6/x
Cross Multiply to get;
19.5x = 6(x + 9)
19.5x = 6x + 54
Solving this gives;
x ≈ 4 mph

Kami is in charge of creating a five-digit code to lock and unlock a secure chamber. She can use any digit from 0 through 9, and she can use each digit as many times as she wants. She knows she wants to start the code with an even number.
How many possible codes that start with an even number could Kami create?
40,000 codes
50,000 codes
400,000 codes
500,000 codes
We will see that there are 50,000 different possible codes that start with an even number.
How many possible codes are there?
We know that the code has 5 digits, each one with 10 possible options (except the first one, when we only can use even digits, so there we have 5 options).
And the numbers can be repeated any number of times through the code, then the total number of different codes that can be made is equal to the product between the numbers of options for each of the digits, we will have:
[tex]C = 5*10*10*10*10 = 50,000[/tex]

y>2x−2
Answer:
y > -2x + 2
Step-by-step explanation:
The dashed line tells us the answer doesNOT have the "or=to" under the inequality symbol. Then the y-intercept is positive 2. So it must be
