Answer: There was a total of 173 animals left by the river
Step-by-step explanation:187+266 = 453
You subtract 453 from the total number of animals which is 632
632-453 = 179

Find an equation equivalent to r = 10 sinθ in rectangular coordinates
Answer:
[tex]x^{2} + y^{2} - 10\cdot y = 0[/tex]
Step-by-step explanation:
The following expressions are used to transform from polar into rectangular form:
[tex]r = \sqrt{x^{2}+y^{2}}[/tex]
[tex]\sin \theta = \frac{y}{\sqrt{x^{2}+y^{2}}}[/tex]
Now, the variables are substituted and equation is finally simplified:
[tex]\sqrt{x^{2}+y^{2}} = 10\cdot \frac{y}{\sqrt{x^{2}+y^{2}} }[/tex]
[tex]x^{2}+y^{2} = 10\cdot y[/tex]
The equivalent equation in rectangular coordinates is:
[tex]x^{2} + y^{2} - 10\cdot y = 0[/tex]

Mr. Wilson wants to build a square roof for his square deck in the back yard.
The roof will be 12 feet long on each side. He uses the formula (A = s) to
find the area of the roof. What will be the area of the square roof on Mr.
Wilson's deck? (give only the number value of your answer) *
Answer:
The area of the square roof is 144 square feet.Step-by-step explanation:
Givens
He wants to build a square roof.The roof will be 12 feet long.We know that the area of a square is
[tex]A=s^{2}[/tex]
Where [tex]s=12 \ ft[/tex], according to the problem.
Replacing this value, we have
[tex]A=(12 \ ft)^{2} =144 \ ft^{2}[/tex]
Therefore, the area of the square roof is 144 square feet.
Answer: the area of the roof is 144 feet squared for each side (up and down), adding to a total of 288 ft^2
Step-by-step explanation:
If the roof is a square with a side lenght L = 12 feet, then we use the fact that the area of a square is equal to the square of the side lenght of the square, this is:
A = L^2 = (12 ft)^2 = 144 ft^2
Now, Mr. wilson uses the equation A = s, this is because the roof has 2 surfaces, one up and one bottom, then the total area is 2 times the value that we find earlier:
2*144 ft^2 = 288 ft^2

Answer:Surface Area of a Solid
The surface area of a 3-dimensional object is the measure of the total area of all its faces. This means that one way to find the surface area of a solid is to find the area of its net. The surface area of a rectangular prism is the area of the six rectangles that cover it.

Solve for x: 1/2(6x - 10) = 2x - 7
Answer:
X=-2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
1/2(6x-10)=2x-7
(1/2)(6x)+(1/2)(-10)=2x+-7(Distribute)
3x+-5=2x+-7
3x-5=2x-7
Step 2: Subtract 2x from both sides.
3x-5-2x=2x-7-2x
X-5=-7
Step 3: Add 5 to both sides.
X-5+5=-7+5
X=-2

Question
A gymnast, who can stretch her arms up to reach 6 feet, jumps straight up on a trampoline. The height of
her feet above the trampoline can be modeled by the equation h =-16x2 + 12x, where x is the time in
seconds after her jump.
Do the gymnast's hands reach a height of 11 feet above the trampoline? Use the discriminant to explain.
(Hint: Since h = height of feet, you must use the difference between the heights of the hands and feet.)
The value of the discriminant is
The discriminant is a (select) number. So, there
(select) real solutions for this height. The gymnast hands (select) reach a height of 11 feet.
Answer:
The discriminant of the equation is less than zero. The gymnast's hands do not reach a height of 11 feet
Step-by-step explanation:
The gymnast's hands does not reach a height of 11 feet above the trampoline.
What is Quadratic Equation?A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is a[tex]x^{2}[/tex] + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term.
It is given that ,
h= [tex]-16x^{2} +12x[/tex]
11-6= [tex]-16x^{2} +12x[/tex]
5 = [tex]-16x^{2} +12x[/tex]
[tex]-16x^{2} +12x[/tex] -5=0
Comparing the above equation with the standard form of quadratic equation [tex]ax^{2} +bx+c=0\\[/tex]
we get ; a=-16, b=12, c=-5
Using Discriminant method
D= [tex]\sqrt[]{b^{2} - 4*a*c}[/tex]
= [tex]\sqrt[]{(12)^{2} - 4* (-16)*(-5)}[/tex]
= [tex]\sqrt[]{144-320}[/tex]
= [tex]\sqrt[]{-176}[/tex]
Hence D<0, which means there is no real value.
So, the gymnast's hands does not reach a height of 11 feet above the trampoline.

c)24°
d)31°
Answer:
b) 14°
Step-by-step explanation:
To solve this, you need to make an equation. since a line is equal to 180°, you can add the two angles together. for example, x+96+5x=180. you would write this because these two angles are on a line, which makes the total sum 180°. now you solve: 6x+96=180. 6x=84. x=14°. :)

C. [tex]F(x) = -x^2 - 3[/tex]
Step-by-step explanation:
The function, F(x), has flipped over the x-axis (as seen) meaning that the function has to have a negative sign in front. The function has also shifted downwards 3 units, meaning that 3 has to have been subtracted from the function.
This makes "C," the correct answer, as it fulfills these requirements.

Half wanted to quit to improve their appearance (yellow teeth and bad breath, etc) and half wanted to quit to improve their health (life expectancy, etc).

2000 m²2827 m²B. MarciStep-by-step explanation:
It is convenient to compute the areas in terms of grid squares. Then those results can be converted to square meters by multiplying by the area of a grid square: (10 m)² = 100 m².
(a) The area of the school is the product of its side dimensions. The short side is (in terms of grid squares) ...
W = √(1²+3²) = √10
The long side is ...
L = √(2²+6²) = √40
Then the area is ...
A = LW = (√40)(√10) = √400 = 20
The area of the school is 20 grid squares = 2000 m² . . . . . where s = 10 m
__
(b) The area of the museum is given by the formula ...
A = πr² = π(3)² = 9π grid squares = 2827 m²
The area of the museum is 2827 m².
__
(c) Marci says the museum has a larger area than the school. She is correct.
Marci should win the debate.
