find the value of Y
.....
Answer:
[tex] y = 6 \sqrt{3} \: units[/tex]
Step-by-step explanation:
In order to find the value of y, first we need to find the length of the perpendicular dropped from one of the vertices of the triangle to its opposite side.
By geometric mean theorem:
Length of the perpendicular
[tex] =\sqrt{9\times 3}[/tex]

How does the graph of f(x) = |x| compare with the graph of g(x) = −2|x|? Select all that apply.
A. The graph of g is a vertical compression of the graph of f.
B. The graph of g is a vertical stretch of the graph of f.
C. The graph of g is a reflection over the x-axis of the graph of f.
Answer:
option A
Step-by-step explanation:
y = k . f( x )
• if k > 1, the graph of y = k•f (x) is the graph of f (x) vertically stretched by multiplying each of its y-coordinates by k.
• if 0 < k < 1 (a fraction), the graph is f (x) vertically shrunk (or compressed) by multiplying each of its y-coordinates by k.
• if k < 0, the vertical stretch or shrink is followed by a reflection across the x-axis.
Given g(x ) = - |x |
= -1 × f(x)
k < 0 , therefore the graph g (x) is a vertical shrink ( or compression ) of graph f
If f (x) = 6x - 6, find f(-1).

Step-by-step explanation:
Hi Alyssa!,
For any x we multiply it by 6 and subtract 6 from it to get the F. The function tells us this. To find f(-1) it bassicly says what's f when x is -1. Well we know that. f is 6(-1)-6 whis is -12.
F is -12

Kalon has $175 and needs to save atleast $700 for a computer.if he can save $35 per week, what is the minimum number for of weeks kalon will need to reach his goal
Answer:
15 weeks
Step-by-step explanation:
First, calculate the total that is needing to be saved not including the money she already has.
So 700 minus 175 is 525.
Next, to find the number of weeks, divide 525 by 35 which gives you 15 even.
So if Kalon continues to save $35 a week, it will take him 15 weeks to reach his goal of $700.

Answer:
[tex]x = \frac{19-2y}{3}[/tex]
[tex]y=-\frac{3x+19}{2}[/tex]
Step-by-step explanation:
4x + y = 22
y = x - 3
4x + y + y = 22 + x - 3
4x + 2y = 19 + x
4x - x + 2y = 19 + x - x
3x + 2y ÷ 3 = 19 ÷ 3
[tex]x = \frac{19-2y}{3}[/tex]
[tex]y=-\frac{3x+19}{2}[/tex]
Answer:
a)Let's solve for x.
4x+y=22
Step 1: Add -y to both sides.
4x+y+−y=22+−y
4x=−y+22
Step 2: Divide both sides by 4.

10.3% of 853.93km rounded to 2 dp
Answer:
87.95479
Step-by-step explanation:
10.3% of 853.93 km
Expand 10.3÷100 by multiplying both numerator and denominator by 10.
[tex] \small \sf \frac{10.3 \times 10}{100 \times 10} = 853.93 \\ [/tex]
[tex] \small \sf \frac{103}{1000} = 853.93 \\ [/tex]
convert decimal number 853.93 to fraction 85394÷100
[tex]\small \sf \frac{103}{1000} = \frac{85393}{100} \\[/tex]
Multiplying 103÷1000 and 85393÷100 by numerator times numerator and denominator times denominator.
[tex]\small \sf \frac{103 \times 8539 3}{1000 \times 100} \\[/tex]
Do the multiplication in the fraction

Answer:
5.74
Step-by-step explanation:
The value of AC in the given right triangle is 5.74 units.
What is Pythagoras theorem?Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle) - a² + b² = c².
Given that, the right triangle ABC, AB = 4 and BC = 7.
According to Pythagoras theorem,
AC² = AB²+BC²
AC² = 7²+4²
AC = √33 = 5.74
Hence, The value of AC in the given right triangle is 5.74 units.

Find the surface area of the cylinder. Round your answer to the nearest tenth.
Answer:
62.8
Step-by-step explanation:
The formula of finding the volume of a cylinder v= pi*r^2*h
So substitute the values:
r is 2, and h is 5
v=pi*2^2*5
Then solve the equation:
v=pi*4*5
v=pi*20
v=62.8 (I multiplied 20 by 3.14, or pi)
So the answer is 62.8

write the standard form of the equation of a circle with a radius of 1 and a center of (-7,1)
Answer:
(x + 7)² + (y - 1)² = 1
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (- 7, 1) and r = 1 , then
(x - (- 7) )² + (y - 1)² = 1² , that is
(x + 7)² + (y - 1)² = 1

Answer:
∠PAO = 90°∠APO = 30°∠AOB = 120°PB ≈ 8.7Step-by-step explanation:
A tangent makes a right angle with the radius to the point of tangency. Hence ∠PAO is 90°. The ratio of the short side (OA) of the right triangle OAP to the hypotenuse (OP) is 5 : 10 = 1 : 2. These are the ratios found in a 30°-60°-90° triangle, so we know that ∠APO = 30°.
OP is a bisector of angle APB, so that angle is 60°. Angle AOB is the supplement to angle APB, so ∠AOB = 120°.
__
As we said above, triangle OAP is a 30°-60°-90° triangle, so its side lengths have the ratios 1 : √3 : 2. This means PA = PB = 5√3 ≈ 8.7.

X=2
Answer:
x = 2
Step-by-step explanation:
2.5(6x - 4) = 10 + 4(1.5 + 0.5x)
Distribute the 2.5
15x - 10 = 10 + 4(1.5 + 0.5x)
Distribute the 4
15x - 10 = 10 + 6 + 2x
Combine like terms
15x - 10 = 16 + 2x
Add 10 to both sides
15x = 26 + 2x
Subtract 2x from both sides
13x = 26
Divide both sides by 13x

The denominator of a fraction is 4 more than twice its numerator. Denominator becomes 12 times the numerator, if both the numerator and the denominator are reduced by 6. Find the fraction.
Answer: [tex]\dfrac{6}{26}[/tex]
Step-by-step explanation:
Given
Denominator is 4 more than twice its numerator
Suppose the numerator is x. So, it follows above condition, fraction becomes
[tex]\Rightarrow \dfrac{x}{2x+4}[/tex]
If both numerator and denominator are reduced by 6, they become equal
[tex]\Rightarrow 12(x-6)=2x+4-6\\\Rightarrow 12x-72=2x-2\\\Rightarrow 10x=70\\\Rightarrow x=7[/tex]
The fraction is
[tex]\Rightarrow \dfrac{x}{4x+2}=\dfrac{6}{4\times 6+2}\\\\\Rightarrow \dfrac{6}{26}[/tex]
