Answer:
y = 2x^2 + 8x + 3
Step-by-step explanation:
Step 1: use the vertex form of the quadratic equation
y = a*(x - h)^2 + k
vertex = (-2, -5) = (h, k)
y = a*(x + 2)^2 - 5
Step 2: determine a using the given point
point = (0, 3)
y = a*(x + 2)^2 - 5
3 = a*(0+2)^2 - 5
3 + 5 = a*(2)^2
8 = a*4
a = 2
vertex equation is now y = 2*(x + 2)^2 - 5
Step 3: simplify vertex equation to standard quadratic equation
quadratic equation = Ax^2 + Bx + C
y = 2*(x + 2)^2 - 5
y = 2*(x^2 + 4x + 4) - 5
y = 2x^2 + 8x + 8 - 5
y = 2x^2 + 8x + 3

Shape A can be transformed to shape B by a rotation 90° clockwise about (-1, 1) followed by a translation by vector
(a b)
Find the values of a and b
The values of a and b if the coordinate is rotated 90° clockwise is -1 and -1
Rotation of coordinatesThe rotation is a transformation technique that changes the position of an object in an xy plane. If the coordinate (x, y) is rotated 90° clockwise, the resulting coordinate will be at (-y, x)
If the coordinate (-1, 1) is therefore rotated 90° clockwise about the origin, the resulting coordinate will be (-1, -1).
Comparing
a = -1 and b = -1
Hence the values of a and b if the coordinate is rotated 90° clockwise is -1 and -1

The correct value of (3cis(pi/6))³ is 27i.
What is Complex Number?Complex numbers are numbers that consist of two parts — a real number and an imaginary number. Complex numbers are the building blocks of more intricate math, such as algebra.
Given the complex number in polar coordinate expressed as
z = r(cos∅+isin∅)
zⁿ = {r(cos∅+isin∅)}ⁿ
According to DeMoivre’s Theorem;
zⁿ = rⁿ(cosn∅+isinn∅)
Given the complex number;
(3cis(pi/6))³
= {3(cosπ/6 + isinπ/6)}³
Using DeMoivre’s Theorem;
= 3³(cos3π/6 + isin3π/6)
= 3³(cosπ/2 + isinπ/2)

Find the sum of the interior angles of the following polygon
Answer:
540° and x = 85°
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 5 , then
sum = 180° × 3 = 540°
2
sum the interior angles and equate to 540°
x + 115° + 95° + 115° + 130° = 540°
x + 455° = 540° ( sum 455° from both sides )
x = 85°

Answer:
P = 156 units
Step-by-step explanation:
the perimeter (P) is the sum of the 3 sides of the triangle.
tangents from an external point to the circle are congruent , that is
HK = HJ ( substitute values )
13x - 8 = 7x + 4 ( subtract 7x from both sides )
6x - 8 = 4 ( add 8 to both sides )
6x = 12 ( divide both sides by 2 )
x = 2
Then
HK = HJ = 7x + 4 = 7(2) + 4 = 14 + 4 = 18
and
KI = IL = 21
then
GL = GJ = 60 - 21 = 39
Thus
P = HK + KI + IG + GJ + JH = 18 + 21 + 60 + 39 + 18 = 156 units
Q varies inversely with x. if q = 12 when x = 5, find the value of q when x = 12.
q varies inversely as x: qx = k, such k is constant
Given values:
q = 12x = 5To determine the constant of variation, substitute the first two given values of q and x to the equation of variation.
qx = k(12)(5) = k60 = kTo determine the value of q, substitute the second given value of x together with the constant of variation.
x = 12, q = ?qx = 6012q = 60q = 60/12q = 5Answer:

A landscaping company has giving quotes to 2 different customers the first customer quote is $287 to install 13 bushes and 7 trees and the second customer' quote is $392 to install 8 bushes and 12 trees
The cost of installing a bush is $7 and the cost of installing a tree is $28
How to determine the cost of bushes and trees?Represent the trees with t and the bushes with b.
So, we have the following equations:
13b + 7t = 287
8b + 12t = 392
Make t the subject in 13b + 7t = 287
t = (287 - 13b)/7
Substitute t = (287 - 13b)/7 in 8b + 12t = 392
8b + 12 * (287 - 13b)/7 = 392
Multiply through by 7
56b + 12 * (287 - 13b) = 2744
Expand
56b + 3444 - 156b = 2744
Collect like terms
56b - 156b = 2744 - 3444
-100b = -700
Divide both sides by -100
b = 7
Substitute b = 7in t = (287 - 13b)/7
t = (287 - 13*7)/7
Evaluate
t = 28
Hence, the cost of installing a bush is $7 and the cost of installing a tree is $28

Hello!
The missing angle in the triangle can be found by subtracting 90° and 45° from 180°. The missing angle is 45°.
This means that the triangle is isosceles, as there are two congruent base angles, 45° and 45°.
The side lengths opposite these two angles are congruent.
We can see that 8 is opposite 45°, and x is opposite 45°. Therefore, x must be equal to 8.
The value of x is 8.
Answer:
x = 8
Step-by-step explanation:
The interior angles of a triangle sum to 180°.
The given triangle is a right triangle, so the missing angle is 45°
⇒ 180° - 90° - 45° = 45°
As the triangle has 2 equal angles, this means it is an isosceles triangle (with its vertex at the right angle). An isosceles triangle has legs of equal measure, therefore [tex]x=8[/tex].
Proof
This can be proven by using the tan trigonometric ratio to calculate the value of x.
Tan trig ratio
[tex]\sf tan(\theta)=\dfrac{O}{A}[/tex]
where:
[tex]\theta[/tex] is the angleO is the side opposite the angleA is the side adjacent the angleGiven:
[tex]\theta[/tex] = 45°O = 8A = xSubstituting the given values into the equation and solving for x:
[tex]\implies \tan (45^{\circ})=\dfrac{8}{x}[/tex]
[tex]\implies x=\dfrac{8}{\tan (45^{\circ})}[/tex]
[tex]\implies x=\dfrac{8}{1}[/tex]
