The equation of a parabola is y=x^2–4x+13. Write the equation in vertex form.

Korolek [52]

Answer:

y = (x - 2)² + 9

Step-by-step explanation:

To obtain the equation in vertex form use the method of completing the square.

Add/ subtract ( half the coefficient of the x- term)² to x² - 4x

y = x² + 2(- 2)x + 4 - 4 + 13

= (x - 2)² + 9 ← in vertex form

Http://prntscr.com/lkz30r What is the value of x? 28 20 36 17

ivolga24 [154]

This is a question that can be solved with Pythagorean Theorem since it is a right triangle. The longest side, 29, is the hypotenuse and the sides 21 and x are the legs. So, the Pythagorean Theorem states,

$c^{2}= a^{2}+ b^{2}$

Where,

c is the Hypotenuse, a and b are the legs. Putting the respective values gives us,

$(29)^{2}= (21)^{2} +x^{2} \\841=441+x^{2} \\400=x^{2} \\20=x$

So, 20 is the side length of x.

A large serving of soup from a take-out restaurant is 4/5 liter. The restaurant has 3 liters of soup. The diagram below models t

Airida [17]

Answer:

The quantity of total serving soup does restaurant has = T = 2 $\dfrac{2}{5}$ liters .

Step-by-step explanation:

Given as :

The quantity of large serving soup = $\dfrac{4}{5}$ liters

The total quantity of soup does restaurant has = 3 liters

Let the quantity of total serving soup does restaurant has = T liters

So, According to question

The quantity of total serving soup does restaurant has = The quantity of large serving soup × total quantity of soup does restaurant has

Or, T = $\dfrac{4}{5}$ × 3

Or, T = $\frac{4\times 3}{5}$

Or, T = $\dfrac{12}{5}$

∴ T = 2 $\dfrac{2}{5}$ liters

So, quantity of total serving soup does restaurant has = T = 2 $\dfrac{2}{5}$ liters

Hence,The quantity of total serving soup does restaurant has = T = 2 $\dfrac{2}{5}$ liters . Answer
