<h3>Answer: The vertex is located at (2, 2)</h3>

====================================================

Explanation:

The general vertex form is

y = a(x-h)^2 + k

When we compare the function your teacher gave you to this template, then we see that

a = 1
h = 2
k = 2

The vertex is therefore (h,k) = (2,2)

The value of 'a' has no role in the vertex's location. This value determines how vertically stretched or compressed the parabola will be. Also, it determines if the parabola opens upward or downward (a > 0 for upward; a < 0 for downward).

X-Intercepts?

valkas [14]

Answer:

x-ints: (2,0) & (4,0)

y-int: (0,-8)

vertex: (3,1) *highest point of the graph

line of symmetry: x = 3 *x-value in the middle of x-ints

a value is -# *if parabola points done it's negative, if it points up it's positive

In the equation z/6 =

Nikitich [7]

Hi there!

»»————-　★　————-««

I believe your answer is:

"Isolate the variable using inverse operations."

»»————-　★　————-««

Here’s why:

To solve for a variable, we would have to isolate it on one side.

To isolate it, we would use inverse operations on both sides on the equation until the variable is isolated.

There are no like terms in the given equation.

⸻⸻⸻⸻

$\boxed{\text{Solving for 'z'...}}\\\\\frac{z}{6} = 36\\-------------\\\rightarrow (\frac{z}{6})6 = (36)6\\\\\rightarrow \boxed{z = 216}$

Hope this helps you. I apologize if it’s incorrect.

Each day, the human heart pumps about 7500 liters of blood. As a simple approximation, assume that the work done by the heart is

erik [133]

Answer with Step-by-step explanation:

We are given

Volume of blood=V=7500 L= $7500\times 0.001=7.5 m^3$

1 liter= $0.001 m^3$

Height of person=h=1.5 m

Density of blood, $\rho=1050 kg/m^3$

We have to find the work done and power of person's heart.

We know that

Work done, $W=mgh=\rho Vgh$

Where $g=9.8 m/s^2$

Using the formula

$W=1050\times 7.5\times 9.8\times 1.5=1.16\times 10^5 J$

Time,t=1 day= $24\times 60\times 60=86400 s$

Power, P= $\frac{W}{t}$

Using the formula

$P=\frac{1.16\times 10^5}{86400}=1.34 Watt$
