The perimeter is 18 sq cm.

2(4) + 2(5)
8 + 10 = 18.

Choose the correct vertex of the function f(x) = x2 - X + 2.

8_murik_8 [283]

Answer:

The vertex of the function is $(\frac{1}{2}, \frac{7}{4})$

Step-by-step explanation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

$f(x) = ax^{2} + bx + c$

It's vertex is the point $(x_{v}, y_{v})$

In which

$x_{v} = -\frac{b}{2a}$

$y_{v} = -\frac{\Delta}{4a}$

Where

$\Delta = b^2-4ac$

If a<0, the vertex is a maximum point, that is, the maximum value happens at $x_{v}$ , and it's value is $y_{v}$ .

f(x) = x² - X + 2.

Quadratic equation with $a = 1, b = -1, c = 2$

$\Delta = b^2-4ac = (-1)^2 - 4(1)(2) = 1 - 8 = -7$

$x_{v} = -\frac{(-1)}{2} = \frac{1}{2}$

$y_{v} = -\frac{-7}{4} = \frac{7}{4}$

The vertex of the function is $(\frac{1}{2}, \frac{7}{4})$

Answer:

The coordinates of the Midpoint of AB will be: (1/2, 5)

Step-by-step explanation:

Given the points

A(-2, 6)

B(3, 4)

Finding the midpoint between (-2, 6) and (3, 4)

$\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)$

$\left(x_1,\:y_1\right)=\left(-2,\:6\right),\:\left(x_2,\:y_2\right)=\left(3,\:4\right)$

$M.P=\left(\frac{3-2}{2},\:\frac{4+6}{2}\right)$

$=\left(\frac{1}{2},\:5\right)$

Therefore, the coordinates of the Midpoint of AB will be: (1/2, 5)

The stadium is like a hemisphere with a radius of 150 feet last month the owners of the stadium paid 0. 05 per cubic foot to cov

GREYUIT [131]

The total cost for utilities last month is 353,571.43.

<h3>What is the total cost for utilities last month?</h3>

The total cost for utilities last month can be determined by multiplying the volume of the stadium by the cost per cubic foot.

The volume of the stadium can be determined by using the formula for the volume of a hemisphere.

Volume of a hemisphere = Volume of a hemisphere = (2/3) x (n) x (r^3)

n = 22/7

r = radius

2/3 x 22/7 x 150³ = 7071,428.57

The total cost for utilities last month = 7071,428.57 x 0.05 = 353,571.43
