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

What value of b will cause the system to have an infinite number of solutions? A system of equations. y equals 6 x plus b. negative 3 x plus StartFraction one-half EndFraction y equals negative 3. A coordinate grid with a line labeled negative 3 x plus StartFraction one-half EndFraction y equals negative 3 and passes through the points (1, 0) and (0, negative 6).

Answers

The value of b that causes the system of equations to have infinite solutions is -6.

How to find the solution to the given system of equations?

For that, we will try solving it first using the method of substitution in which we express one variable in another variable's form and then you can substitute this value in another equation to get a linear equation in one variable.

If there comes a = a situation for any a, then there are infinite solutions.

If there comes wrong equality, say for example, 3=2, then there are no solutions, else there is one unique solution to the given system of equations.

In the given problem, our equations are:

y = 6x + b

-3x + (1/2)^y = -3

So the value of b needs to be such that these two equations must be equal.

In the second equation:

[tex](1/2)^y = -3 + 3x\\y = -3^2 + 3x^2 \\y = -6 + 6x[/tex]

Then we must have:

6x - 6 = 6x + b

-6 = b

Thus, the value of b that causes the system to have infinite solutions is -6.

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

Answers

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

Q varies inversely with x. if q = 12 when x = 5, find the value of q when x = 12.

Answers

Inverse Variation

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 = 5

To 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 = k

To 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 = 5

Answer:

The value of q is 5.

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

Answer:

Step-by-step explanation:

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 angle

Given:

[tex]\theta[/tex] = 45°O = 8A = x

Substituting 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]

[tex]\implies x=8[/tex]

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)

= 3³(0 + i(1))

Find the sum of the interior angles of the following polygon

Answers

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 )
