The Ferrari Sports Car is a tenth second slower than the Lamborghini Sports Car.
The Renault Sports Car is three tenths of a second faster than the McLaren Sports Car.
What time does the Renault Sports Car displays to reache a maximum speed of 200km/h?

Answers

The Renault Sports Car displays 15.70 seconds to reache at maximum speed of 200km / h.

Since the Lamborghini Sports Car reaches a maximum speed of 200km / h in 15.50s, the McLaren Sports Car displays the same time as the Ferrari Sports Car, the Ferrari Sports Car is a tenth second slower than the Lamborghini Sports Car, and the Renault Sports Car is three tenths of a second faster than the McLaren Sports Car, to determine what time does the Renault Sports Car displays to reache a maximum speed of 200km / h the following calculation must be performed:

15.5 - 0.1 + 0.3 = X 15.4 + 0.3 = X 15.7 = X

Therefore, the Renault Sports Car displays 15.70 seconds to reache at maximum speed of 200km / h.

Answer:

x=8°

Step-by-step explanation:

Let's make an equation with this problem, since all side have to add up to 180 degrees we can solve it

(5x-2)+(9x+3)+(11x-21)=180°

lets add up light terms

25x-20=180°

add both sides by 20 and we get 25x=200°

divide both sides by 25 and we get x=8°

We have: (9x+3) + (5x-2) + (11x-21) = 180
=> 9x + 5x + 11x = 180 + 21 + 2 - 3
=> 25x = 200
=> x = 8

The graph of a quadratic function is always a parabola. The vertex of the parabola after transformation is (-1,-4).

What is a quadratic equation?

A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.

The graph of the two functions can be made as shown below. Therefore, the two functions are,

y=2x² → Drawn by the red line

y = 2(x + 1)² − 4 → Drawn by the blue line

Now, the vertex of a quadratic function or a parabola is the point at which the function or the parabola changes its slope, it's either the maximum of the function or the minimum of the function, depending on which side the parabola opens.

Hence, The vertex of the parabola after transformation is (-1,-4).
