I hope my answer helps you.
Answer:
x = 20
y = 17.32
Step-by-step explanation:
[tex]10 = x \cos 60 \degree \\ \\ \implies \: 10 = x \times \frac{1}{2} \\ \\ \implies \: 10 \times 2= x \\ \\ \implies \: \huge{ \boxed{x = 20}} \\ \\ y = 10 \tan \: 60 \degree \\ \\ \implies \: y = 10 \times \sqrt{3} \\ \\\implies \: y = 10 \times 1.732 \\ \\\implies \: \huge{ \boxed{ y = 17.32}}[/tex]

Answer:
(x-8)^2+(y+8)^2=7
Step-by-step explanation:
The equation of a circle is (x-h)^2+(y-k)^2=r^2
Substitute h, k, and r for 8, -8, and √7, respectively.
(x-(8))^2+(y-(-8))^2=(√7)^2
The two negatives in y - (-8) causes it to be a +8. Squaring √7 will make it 7.

Wayne designed the table shown below for an x-ray room. He wants to cover the shaded rectangular surfaces of the table, marked A, B and C, with a sheet of soft foam padding.
What is the total area of the 3 rectangular surfaces to be covered with foam padding?
Answers
The total surface area of surface 3 rectangular surfaces to be covered with foam padding is 36 ft²
What is an area?The area is the amount of space occupied by a two dimensional shape or object.
Area of rectangle = length * width
Area of surface A = 1 ft * 4.5 ft = 4.5 ft²
Area of surface B = 0.5 ft * 4.5 ft = 2.25 ft²
Area of surface C = 6.5 ft * 4.5 ft = 29.25 ft²
Total area = 29.25 + 2.25 + 4.5 = 36 ft²
The total surface area of surface 3 rectangular surfaces to be covered with foam padding is 36 ft²

Mrs. Reyes had some apples. If she gave each student 3 apples, she would have 2 apples left have. If she gave each students 4 apples each she would be 2 short. How many apples did she have.
Answers
Answer:
14 applesStep-by-step explanation:
Let
Number of apples = aNumber of students = sAccording to question we have equations
a = 3s + 2a = 4s - 2Find the number of students by substitution
3s + 2 = 4s - 24s - 3s = 2 + 2s = 4Find the number of apples
a = 3*4 + 2 = 12 + 2 = 14Answer:
14 apples
Step-by-step explanation:
Let x = number of students
Let y = total number of apples
Create a system of equations with the given information.
Equation 1
If she gave each student 3 apples, she would have 2 apples left:
⇒ y - 3x = 2
Equation 2
If she gave each students 4 apples each she would be 2 short:
⇒ y - 4x = -2
Rewrite Equation 1 to make y the subject:
⇒ y = 2 + 3x
Substitute this into Equation 2 and solve for x:
⇒ (2 + 3x) - 4x = -2
⇒ 2 + 3x - 4x = -2
⇒ 2 - x = -2
⇒ -x = -4
⇒ x = 4
Substitute the found value of x into the rewritten Equation 1 and solve for y:
⇒ y = 2 + 3(4)
⇒ y = 2 + 12
⇒ y = 14
Therefore, Mrs Reyes had 14 apples.

You look up at a drone at an angle of elevation of 23º. Your eyes are 5 feet above the ground, and the distance to
the drone is 210 feet. What is the altitude of the drone? Round your answer to the nnearest tenth.
Altitude: about ___
feet
Answers
Using the slope concept, it is found that the height of the drone is of about 94 feet.
What is a slope?The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.
In this problem:
The vertical change is of h - 5, in which h is the altitude of the drone.The horizontal change is of 210 ft.The angle is of 23º.Hence:
[tex]\tan{23^\circ} = \frac{h - 5}{210}[/tex]
[tex]h - 5 = 89[/tex]
[tex]h = 94[/tex]
The height of the drone is of about 94 feet.

Express the function graphed on the axes below as a piecewise function.
Answers
Answer:
f(x) = {x-3 for x ≤ -1; -3x+14 for x > 5}
Step-by-step explanation:
To write the piecewise function, we can consider the pieces one at a time. For each, we need to define the domain, and the functional relation.
__
Left PieceThe domain is the horizontal extent. It is shown as -∞ to -1, with -1 included.
The relation has a slope (rise/run) of +1, and would intersect the y-axis at -3 if it were extended.
The first piece can be written ...
f(x) = x-3 for x ≤ -1
__
Right PieceThe domain is shown as 5 to ∞, with 5 not included.
The relation is shown as having a slope (rise/run) of (-3)/(1) = -3. If extended, it would intersect the point (5, -1), so we can write the point-slope equation as ...
y -(-1) = -3(x -5)
y = -3x +15 -1 = -3x +14
The second piece can be written ...
f(x) = -3x +14 for x > 5
__
Whole functionPutting these pieces together, we have ...
[tex]\boxed{f(x)=\begin{cases}x-3&\text{for }x\le-1\\-3x+14&\text{for }5 < x\end{cases}}[/tex]
_____
Additional comment
Sometimes it is convenient to write inequalities in number-line order (using < or ≤ symbols). This gives a visual indication of where the variable stands in relation to the limit(s). Perhaps a more conventional way to write the domain for the second piece is, x > 5.

Calculate the zeros of the function f(x) = x2 – 12x + 35 by completing the square.
Answers
Answer:
x = 5, x = 7
Step-by-step explanation:
to find the zeros let f(x) = 0 , that is
x² - 12x + 35 = 0 ( subtract 35 from both sides )
x² - 12x = - 35
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 6)x + 36 = - 35 + 36
(x - 6)² = 1 ( take the square root of both sides )
x - 6 = ± [tex]\sqrt{1}[/tex] = ± 1 ( add 6 to both sides )
x = 6 ± 1
then
x = 6 - 1 = 5
x = 6 + 1 = 7
