The given quadratic equation 3x^2 – 24x + 10 can be written in vertex form that is f(x) = 3(x – 4)2 – 38.

<h3>What are quadratic equations?</h3>

A quadratic equation is an equation of degree 2 and the standard form of a quadratic equation ax^{2} +bx+c where x is the variable and a,b, c are real numbers.

Following the steps already shown to transform the given function into the vertex form,

f(x) = 3(x^{2}  - 8x + 16) + 10 - 3(16)\\f(x) = 3(x - 4)(x - 4) + 10 - 48\\f(x) = 3(x - 4)2 - 38

Therefore, the function written in vertex form is f(x) = 3(x – 4)2 – 38.

What are similarities between rigid and nonrigid transformations?
Dimas [21]

Answer:

here are four main types of transformations: translation, rotation, reflection and dilation. These transformations fall into two categories: rigid transformations that do not change the shape or size of the preimage and non-rigid transformations that change the size but not the shape of the preimage

Use the information provided to write the equation of the circle Center: (10,-9) Point on Circle: (12,-13)
Zielflug [23.3K]

Answer:

(x - 10)² + (y + 9)² = 20

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

The radius is the distance from the centre to a point on the circle

To calculate r use the distance formula

r = √(x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (10, - 9) and (x₂, y₂ ) = (12, - 13)

r = \sqrt{(12-10)^2+(-13+9)^2}

  = \sqrt{4+16} = \sqrt{20}, hence

(x - 10)² + (y - (- 9))² = (\sqrt{20})², that is

(x - 10)² + (y + 9)² = 20

Question is attached
RoseWind [281]

Answer: A, 63 minutes

Step-by-step explanation:

We can start by making this into two ratios. Isa finished 30% in 27 minutes, so 30/27 is our first ratio. We want to know how long it will take for the rest of the homework to be completed. 30% is finished already, which leaves 70% (100-30=70). The time left is x. Our second ratio is 70/x. Now, we can set the two ratios equal to each other to solve for x.

\frac{30}{27} = \frac{70}{x}

We can now cross multiply.

30x= 27(70)

Now, we simplify the right side.

30x= 1890

Divide both sides by 30 to isolate x.

x= 63

And there's your answer! Hope this helped!
