Y = 3(x-2)^2 + 5
Orlov [11]

The y-intercept coordinate is at the point (0, 17)

<h3>Properties of functions</h3>

Given the following function expressed as:

y = 3(x-2)^2 + 5

  • The vertex of the function (h, k) is (2, 5) while the axis of symmetry is at x = 2
  • Domain are the input values for which the function exist. According to the function, the domain and  range exists on all real values

The x-intercept is the point where y = 0

3(x-2)^2 + 5=0\\3(x-2)^2  = -5\\(x-2)^2 = -5/3\\x - 2 = 25/9\\x = 25/9 + 2\\x = \frac{43}{9}

Hence the x-intercept is (43/9, 0)

The y-intercept is the point where x = 0

y=3(x-2)^2 + 5\\y=3(-2)^2 + 5\\y=12+5\\y=17

The y-intercept coordinate is at the point (0, 17)

treasury bills (t-bills) can be purchased from the U.S. Treasury department. You buy a t-bill for 981.60 that pays 1,000$ in 13
Mnenie [13.5K]

Answer:The simple interest rate is 7.50%

Step-by-step explanation:

Simple interest, I =( P × T × R) / 100

Where P= Principal investment

T = Time in years

R = rate

Given

P= 981.60

I = 1000 - 981.60 = 18 .40

T = 13 weeks = 13 / 52 = 0.25 year

I =( P × T × R) / 100

Cross multiply

I × 100 = P × T × R

18.40 × 100 = 981.60 × 0.25 × R

1840 = 245.4 R

R= 1840 / 245.4

R = 7.498%

To the nearest tenth

R = 7.50%

Write an equation to represent the following: Three consecutive integers add up to 11 more than the smallest.
mr Goodwill [35]

Answer:


Step-by-step explanation:

First we have to assume the smallest integer.

Let,

the smallest integer is  x

So, the other two integers are-

x+1  and   x+2

Now,  

the sum of these 3 integers is greater than smallest integer by  11

So, we get

x+(x+1)+(x+2) =x+11

This is the required equation.
