Please help me this is confusing please add an explanation to it

Answer:

Step-by-step explanation:

As it would look better.

1 would make the graph too big

12 would be useless as there are no "answers" more than 12

10 would be useless too as the biggest number used is 10. therefore, 5, 7 would be cramped and too hard to figure out.

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)

Reduce to simplest form.

Shkiper50 [21]

Answer:

11/6

Step-by-step explanation:

$\dfrac{6}{3}+\left(-\dfrac{1}{6}\right)=\dfrac{12}{6}-\dfrac{1}{6}=\dfrac{12-1}{6}\\\\=\boxed{\dfrac{11}{6}}$

As a mixed number, this is 1 5/6.

22. Find the perimeter of the square:<br> 28

sergejj [24]

Answer:

56√2 ≈ 79.20

Step-by-step explanation:

The hypotenuse of an isosceles right triangle is √2 times the side length, so the side length here is ...

s·√2 = 28

s = 28/√2

The perimeter is 4 times the side length, so is ...

P = 4s = 4·28/√2

= 4·28·(√2)/2 . . . . . multiply by (√2)/(√2) to rationalize the denominator

= 56√2 ≈ 79.195959

The perimeter of the square is 56√2, about 79.20 units.

The answer for 10 2/3×31/8 rounded to the nearest whole number?

BigorU [14]

$10 \frac{2}{3} ( \frac{31}{8})$ can be changed into this equation:

$\frac{32}{3}( \frac{31}{8} )$

The 32 and 8 have a common factor of 8 and can be simplified to become this equation:

$\frac{4}{3} ( \frac{31}{1})$

Now multiply across to get $\frac{124}{3}$ which then simplifies to $41 \frac{1}{3}$ which as a decimal is 41.333 (repeating 3s). Nearest whole number is 41.

Your answer is 41
