LuckyWell [14K]

Answer:

50 in ^3

Step-by-step explanation:

V = 1/3 pi r^2 h

We know that pi = 3

the diameter is 5 so the radius is 1/2 the diameter of 5/2 = 2.5

The height is 8

V = 1/3 ( 3) ( 2.5)^2 ( 8)

V = 50 in ^3

Heather measures the temperature of her coffee to be 133.4 degrees fahrenheit. It is actually 145 degrees fahrenheit. What is th

zhenek [66]

Answer:

The percent error of Heather's calculation is 8%.

Step-by-step explanation:

Given:

Heather measures the temperature of her coffee to be 133.4 degrees fahrenheit. It is actually 145 degrees fahrenheit.

Now, to find the percent error of Heather's calculation.

The temperature of coffee Heather measures = 133.4° F.

Coffee's actual temperature = 145° F.

So, to get the measurement in error we subtract the temperature of coffee Heather measures from coffee's actual temperature:

$145-133.4=11.6\°.$

Now, to get the percent error:

$\frac{11.6}{145}\times 100$

$=\frac{1160}{145}$

$=8\%.$

Therefore, the percent error of Heather's calculation is 8%.

What are the domain and range of f(x)=log(x-1)+2?

marta [7]

Answer: Domain = $(-1, \infty)$

Range = $(-\infty, \infty)$

Step-by-step explanation:

Here, the given function,

$f(x) = log(x-1) + 2$

Since log( negative number ) = not defined

Also,

$log(0) = -\infty$

Hence, f(x) is defined if x - 1 > 0

⇒ x > 1

Thus, f(x) is defined for all the values that are greater than 1,

⇒ Domain of f(x) = All real number greater than 1,

= $(1, \infty)$

Now, for the interval $(1, \infty)$ ,

f(x) can be any real number.

Thus, the range of the given function = $(-\infty, \infty)$
