Find the missing side of each right triangle. Side c is the hypotenuse. Sides a and bare
the
legs. Round your answers to the nearest tenth if necessary.
a = 8.8 ft, b = 9 ft
Answer: 12.6 ft
Step-by-step explanation:
a = 8.8 ft
b = 9 ft
c = ?
Since it is a right triangle, we can use the Pythagorean Theorem to solve for missing side c, the hypotenuse.
a^2 + b^2 = c^2
(8.8)^2 + (9)^2 = c^2
158.44 = c^2
(158.44)^(1/2) = c
12.5873 = c
c = 12.6 ft (rounded to the nearest tenth)

Complete the solution of the equation. Find the
value of y when x equals 15.
-3x - y = -51
Answer:
The solution of the equation y = 36
Step-by-step explanation:
Explanation:-
Given equation -3x-y =-51
Given that x =15 in equation -3x-y=-51
⇒ - 3(15) - y = -51
⇒ - 15 - y =-51
⇒ -15+ 51 = y
⇒ y = 36

2x + y = 11
3x - y = 4
Answer:
[tex]x=3,y=5[/tex]Step-by-step explanation:
Add the equations together and solve for x.
[tex](2x + y )+ (3x - y) = 11 + 4[/tex]
[tex]5x=15[/tex]
[tex]x=3[/tex]
Use equation [tex]2x+y=11[/tex] to solve for y.
[tex]2(3) +y=11[/tex]
[tex]6+y=11[/tex]
[tex]y=11-6[/tex]

Jamal wants to install a rectangular 2025 cm² window in his garden shed. That area of window comes in several length/width combinations, and he wants to minimize the perimeter to prevent drafts. What is the least perimeter possible for the window?
Answer:
The ideal size will be a 45cmx45cm square, giving you a perimeter of 180cm.
Step-by-step explanation:
The shortcut answer here is that the square will always be the most efficient rectangle for border to area, so the sides should be the square root of 2025 cm, or 45 cm each, giving you a total of 180 minimum perimeter.
The full solution is to express the perimeter as a function of the length and width, define either length or width as a function of the other, take the entire expression's derivative and solve for zero. Let's do it:
So first the area:
2025 = wl
l = 2025 / w
Now the sides:
[tex]p = 2w + 2l\\p = 2w + 2(2025 / w)\\p = 2w + 4050 / w[/tex]
Then we can take its derivative with respect to w
[tex]p = 2w + 4050\frac{1}{w}\\\frac{dp}{dw} = 2 + 4050\frac{-1}{w^2}\\[/tex]
Now we can set the derivative to zero, and solve for w:
[tex]\frac{dp}{dw} = 2 + 4050\frac{-1}{w^2}\\0 = 2 + \frac{-4050}{w^2}\\-2 = \frac{-4050}{w^2}\\2w^2 = 4050\\w^2 = 2025\\w = \sqrt{2025}\\w = 45[/tex]
So the width being 45, we can get the length by dividing the area by that amount, which of course is also 45.

y = 2(x – 3)2 - 4
Convert to standard form
Answer:
4x - y = 16
Step-by-step explanation:
y = 2(x – 3)2 - 4
When written in standard form, this will be the answer --->
4x - y = 16
Answer:
y = 2x² - 12x + 14
Step-by-step explanation:
The equation of a parabola in standard form is
y = ax² + bx + c ( a ≠ 0 )
Given
y = 2(x - 3)² - 4 ← expand (x - 3)² using FOIL
= 2(x² - 6x + 9) - 4 ← distribute parenthesis
= 2x² - 12x + 18 - 4
y = 2x² - 12x + 14 ← in standard form
The ordered pairs (8,12). (16, 24), (x, 21), (26, y) represent a proportional relationship
Find the value of x and the value of y.
Select the two correct answers.
A y=56
B. x= 14
C. x=7
D. y=39
Ex= 9
F. y = 42
Answer: B. x= 14
D. y=39
Step-by-step explanation:
First and foremost, we need to calculate the constant of proportionality. This will be:
(8,12).
y = kx.
12 = 8k
k = 12/8
k = 1.5
(16, 24),
y = kx
24 = 16k
k = 24/16
k = 1.5
(x, 21),
y = kx
x = y/k
x = 21/1.5
x = 14
(26, y)
y = kx
y = 26 × 1.5
y = 39
Work out the PED for each, and comment on your result. The price of a smartphone is currently £200, and the quantity demanded is 4m. Next year the price falls to £180 and the quantity demanded rises to 6m. The price of pens today is £1, and the quantity demanded is 1m. Next year the price rises to £1.10 and the quantity demanded falls to 950,000. The price of a daily newspaper today is £1.50p, and the quantity demanded is 2m. Next year the price falls by 30p and the quantity demanded rises to 2.2m Question 2
Answer:
a.) PED = 5
b.) PED = 5
c.) PED = 0.05
Step-by-step explanation:
Here , PED = Price elasticity of demand
a.)
Given - The price of a smartphone is currently £200, and the quantity demanded is 4m. Next year the price falls to £180 and the quantity demanded rises to 6m.
PED = (Change in quantity demanded)×[tex]\frac{Initial Price}{Initial Quantity demanded}[/tex]
Now,
Change in quantity demanded = [tex]\frac{6 - 4}{180 - 200}[/tex] = [tex]\frac{2}{20} = \frac{1}{10}[/tex]
⇒PED = [tex]\frac{1}{10}[/tex]×[tex]\frac{200}{4}[/tex] = 5
b.)
Given -The price of pens today is £1, and the quantity demanded is 1m. Next year the price rises to £1.10 and the quantity demanded falls to 950,000.
Change in quantity demanded = [tex]\frac{1000000 - 950000}{1.10- 1}[/tex] = [tex]\frac{50000}{0.10} = 500000[/tex]
⇒PED = [tex]500000[/tex]×[tex]\frac{1}{1000000}[/tex] = 5
c.)
Given -The price of a daily newspaper today is £1.50p, and the quantity demanded is 2m. Next year the price falls by 30p and the quantity demanded rises to 2.2m
Change in quantity demanded = [tex]\frac{2.2 - 2}{30 - 1.50}[/tex] = [tex]\frac{0.2}{28.50} = \frac{20}{2850} = \frac{2}{285}[/tex]
⇒PED = [tex]\frac{2}{285}[/tex]×[tex]\frac{1.50}{2}[/tex] = [tex]\frac{15}{2850}[/tex]= [tex]\frac{1}{190}[/tex] = 0.005
