Answer:
A = 153.94 sq mi
Step-by-step explanation:
In this scenario, we would be starting from the center point and searching the area of a square since the distance in every direction would the same 7 mi. This 7-mile distance would be our radius in this scenario. We now need to use the formula for the Area of a circle to calculate the search area. This formula is the following
A = [tex]\pi r^{2}[/tex]
A = [tex]\pi 7^{2}[/tex]
A = [tex]\pi 49[/tex]
A = 153.94 sq mi
A total of 153.94 square miles must be searched.

3x - 2y = -1 ; -x + 2y = -5
Answer: 1
−x+2y=−5;3x−2y=−1
Step: Solve−x+2y=−5for x:
−x+2y=−5
−x+2y+−2y=−5+−2y(Add -2y to both sides)
−x=−2y−5
−x
−1
=
−2y−5
−1
(Divide both sides by -1)
x=2y+5
Step: Substitute2y+5forxin3x−2y=−1:
3x−2y=−1
3(2y+5)−2y=−1
4y+15=−1(Simplify both sides of the equation)
4y+15+−15=−1+−15(Add -15 to both sides)
4y=−16

4
(Divide both sides by 4)
y=−4
Step: Substitute−4foryinx=2y+5:
x=2y+5
x=(2)(−4)+5
x=−3(Simplify both sides of the equation)

Trigonometric Ratios
The ratios between the sides of a right triangle are called trigonometric ratios.
If any of the acute angles is chosen as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides and the hypotenuse.
The image shows a right triangle with a tree and the ground forming a right angle and an elevation angle of 33°.
This angle of 33° has a side of 30.5 m as its adjacent leg and the height of the tree X as the opposite side.
The trigonometric ratio that relates both legs is the tangent:
[tex]\displaystyle \tan 33^\circ=\frac{X}{30.5}[/tex]
Solving for X
[tex]X=30.5\cdot \tan 33^\circ[/tex]
Using a calculator:
X = 19.81 m
The height of the tree is 19.81 m
Anna has a total of 36 goldfish in her aquarium, some are orange and some are black. The number of orange goldfish is 7 more than twice the number of black goldfish. Which system of equations below can be used to describe the number of black and orange goldfish in Anna's aquarium?
Answer:
x + y = 36.....Equation 1
x = 7 + 2y...... Equation 2
Step-by-step explanation:
Let the number of:
Orange goldfish = x
Black gold fish = y
Anna has a total of 36 goldfish in her aquarium, some are orange and some are black.
x + y = 36.....Equation 1
The number of orange goldfish is 7 more than twice the number of black goldfish.
x = 7 + 2y...... Equation 2
We can rewrite this as:
x - 2y = 7..... Equation 2
The system of equations below that can be used to describe the number of black and orange goldfish in Anna's aquarium is :
x + y = 36.....Equation 1
x = 7 + 2y...... Equation 2
I think it’s
X + y= 36
X - 2y= 7

What is the slope of a line that passes through the points (8,-3) and (-2,5)
Answer:
-4/5
Step-by-step explanation:
Please answer thank you
Answer:
0. If it's a horizontal line, then the slope if automatically 0. if the line went straight up the slope would be "no slope" or "unidentified" your problem has a horizontal line so the slope is 0

Answers:
a = 8r = -15%y = 4.9 approximatelyNote: your teacher may want you to type in a positive value for r
=========================================================
Explanation:
The given equation y = 8(1-0.15)^t is in the form y = a(1+r)^t
We have a = 8 as the initial value, or what we start with.
r = -0.15 converts to -15%, so we have a decay of 15%
Plug in t = 3 to find the corresponding value of y
y = 8(1-0.15)^t
y = 8(1-0.15)^3
y = 8(0.85)^3
y = 8(0.614125)
y = 4.913
y = 4.9
Answer:
a = 8
r = 85%
y = 4.913
Step-by-step explanation:
For a, the exponential decay function is y=a*r^t. In order to find the initial amount, you are solving for when t = 0 or, y(0). Thus, t, or time, is 0. Solve the equation with time of 0.
y = 8(1-0.15)^0 = 8*1 (anything to the 0 power equals 1)
a = 8 is the initial amount
In order to solve for r, you need to solve (1 - 0.15) = 0.85. Now, multiply by 100 to get the percent 100 * 0.85 = 85%
Lastly, when t = 3 solve the equation filling in the exponent, t with 3 like below:
y = 8(1-0.15)^3 (PEMDAS; parenthesis and exponents first)
y = 8(0.85)^3 = 8*(0.614125)
y = 4.913

Answer:
x = 2 and y = 5
Step-by-step explanation:
Given
x = y - 3.....i)
2x + 3y = 19.........ii)
Putting x = y - 3 in equation II)
2( y - 3 ) + 3y = 19
2y - 6 + 3y = 19
5y = 19 + 6
5y = 25
y = 25 / 5
y = 5
Now putting y = 5 in equation i)
x = 5 - 3
x = 2
