Re-write the quadratic function below in Standard Form y=-3 (x - 2)² – 7

Mathematics
1 answer:
pav-90 [236]2 years ago
3 0

Answer:

y=-3x^2+12x-19

Step-by-step explanation:

we know that

The quadratic equation in standard form is equal to

y=ax^{2} +bx+c

we have

y=-3(x-2)^{2}-7

This is a quadratic equation in vertex form

Convert to standard form

y=-3(x^2-4x+4)-7

Apply distributive property

y=-3x^2+12x-12-7

Combine like terms

y=-3x^2+12x-19 ----> quadratic equation in standard form

An object is launched from a launching pad 208 ft. above the ground at a velocity of 192ft/sec. what is the maximum height reach
loris [4]

Answer:

The maximum height is 784 feet

Step-by-step explanation:

In this problem we use the kinematic equation of the height h of an object as a function of time

h(t) = -16t ^ 2 + v_0t + h_0

Where v_0 is the initial velocity and h_0 is the initial height.

We know that

v_0 = 192\ \frac{ft}{sec}

h_0 = 208\ ft.

Then the equation of the height is:

h(t) = -16t ^ 2 + 192t +208

For a quadratic function of the form ax ^ 2 + bx + c

where a

the maximum height of the function is at its vertex.

The vertice is

x = -\frac{b}{2a}\\\\y = f(\frac{-b}{2a})

In this case

a = -16\\b = 192\\c = 208

Then the vertice is:

t = -\frac{192}{2(-16)}\\\\t = 6\ sec

Now we calculate h (6)

h(6) = -16(6) ^ 2 +192(6) +208\\\\h(6) = 784\ feet

The maximum height is 784 feet

A hairstylist earns $12.95/h and works 32 hours a week.
Mrac [35]
So you multiply her hourly wage by how many hours she works

12.95x32=414.40

But then you have to add the amount she makes in tips

414.40+219=633.40

Hope this helps you!

If 400 students at the school took the SAT, how many scored in the 1301 to 1600 range?
harina [27]

Answer:

56 students scored in the range of 1301 to 1600.

Step-by-step explanation:

The given question is without any figure or attachment. Here is the figure attached with the answer.

In the figure attached,

total number of students who took SAT = 400

Percentage of the students who scored 1301 to 1600 range = 14% (given in the pie chart)

Total number of students who are in this range = 14% of total number of students

= 400\times\frac{14}{100}

= 56

Therefore, 56 students scored in the range of 1301 to 1600.
