For some medical imaging, the scale of the image is 5 : 1. That means that if an image is 5 cm long, the corresponding length on

the person's body is 1 cm. Find the actual area of a lesion if its image has area 7.5 cm squared.

I believe it would be 1.5 cm squared because 7.5/5 = 5

Find the average rate of change for the given function over the indicated values of x. If necessary, round your final answer to

Pavlova-9 [17]

Answer:

The average rate of change of the function in this interval is of 18.

Step-by-step explanation:

The average rate of change of a function $f(x)$ in an interval from a to b is given by:

$A = \frac{f(b) - f(a)}{b - a}$

In this question:

$f(x) = x^2 + 6x$

Where x goes from 5 to 7.

This means that $b = 7, a = 5$ . So

$f(7) = 7^2 + 6(7) = 49 + 42 = 91$

$f(5) = 5^2 + 6(5) = 25 + 30 = 55$

The rate of change is:

$A = \frac{f(7) - f(5)}{7 - 5} = \frac{91 - 55}{2} = 18$

The average rate of change of the function in this interval is of 18.

horrorfan [7]

For this case, the first thing we are going to do is define the following equation:
N = (number of cups) / (capacity of a quart container)
Where,
N: number of containers.
We have then:
N = (240) / (1/4)
N = 960 containers
Answer:
kat will need:
N = 960 containers

A diver swims 20 m under water to the anchor of a buoy that is 10 m below the surface of the water. On the surface how far is th

djverab [1.8K]

Answer:

There the buoy is 17.3 m from the place where the diver started.

Step-by-step explanation:

a² + b² =c²

⇒ 10² + b² = 20²

⇒ 100 + b² = 400

⇒ b² = 400 - 100

⇒ b²= 300

⇒ b = $\sqrt{300}$

⇒ b = 17.3 m

There the buoy is 17.3 m from the place where the diver started.

evablogger [386]

Answer:

1.8 or 9/5

Step-by-step explanation:

4 $\frac{1}{2}$ ÷ $2\frac{1}{2}$

Change into improper fractions

$\frac{9}{2}$ ÷ $\frac{5}{2\\}$

Flip the second fraction and then multiply

$\frac{9}{2}$ × $\frac{2}{5}$ = $\frac{18}{10}$

18/10 is 1.8 as a decimal and 9/5 simplified
