the answer is 153.86 ft squared

= the formula for the area of a circle is A=πr2

= area = pi x radius squared

= the radius is 7 feet, square that to get 49

= multiply 49 by pi to get the area: 153.86 square feet

Answer:

153.86 ft squared

Step-by-step explanation:

As per given question we have provided that :

➟ Radius of circular pool = 7 feet

We need to find :

➟ Area of circular pool

Here's the required formula :

${\dashrightarrow\sf{A = \pi {r}^{2}}}$

↝ A = Area
↝ π = 3.14
↝ r = radius

Substituting all the given values in the formula to find the area of circular pool :

${\dashrightarrow{\sf{Area = \pi {r}^{2}}}}$

${\dashrightarrow{\sf{Area = 3.14{(7)}^{2}}}}$

${\dashrightarrow{\sf{Area = 3.14{(7 \times 7)}}}}$

${\dashrightarrow{\sf{Area = 3.14{(49)}}}}$

${\dashrightarrow{\sf{Area = 3.14 \times 49}}}$

${\dashrightarrow{\sf{Area = 153.86}}}$

$\star{\underline{\boxed{\sf{\red{Area = 153.86 \: {ft}^{2}}}}}}$

Hence, the area of circular pool is 153.86 ft².

please help!!! the study conducted was 6 days long: there was 72mm of plant food and it decreased an equal amount each day.

Anuta_ua [19.1K]

Answer:

$f(x) = 72 - 12x$

Step-by-step explanation:

No. of days of study = 6

Amount of food to use for the 6 days = 72 mm

Given that equal amount of food was used each day, amount used per day = $\frac{72}{6} = 12 mm$

This would enable us derive a function for the amount of food remaining f(x), which can be expressed as a function of the number of days that have passed, (x).

Thus, we would have:

$f(x) = 72 - 12x$

Let's check if this equation expresses the relation of the function well.

At the end of day 1, if we used, 12mm, we would have 72 - 12 = 60mm of food remaining.

If we replace x in the equation we derived, we would get the same 60mm as the amount of food remaining.

If you try 2, 3, 4, 5 days, you'd get same thing.

At the end of the study, after the 6th day, the food would remain nothing.

Replace 6 for x in the relation function derived, you'd get a value of 0.

What is the derivative of y with respect to x if y = 2/X4

zepelin [54]

You're correct, the answer is C.

Given any function of the form $y=x^n$ , then the derivative of y with respect to x ( $\frac{dy}{dx}$ ) is written as:
$\frac{dy}{dx}=nx^n^-^1$

In which $n$ is any constant, this is called the power rule for differentiation.

For this example we have $y= \frac{2}{x^4}$ , first lets get rid of the quotient and write the expression in the form $y=x^n$ :
$y= \frac{2}{x^4} =2x^-^4$

Now we can directly apply the rule stated at the beginning (in which $n=-4$ ):
$\frac{dy}{dx}=(2)(-4)x^{-4-1}=-8 x^{-5}= -\frac{8}{x^5}$

Note that whenever we differentiate a function, we simply "ignore" the constants (we take them out of the derivative).

Sarah is purchasing pencils to share. Each package has 12 pencils. The equation n = 12p, where n is the total number of pencils

podryga [215]

Answer and Step-by-step explanation:

Each package has 12 pencils

total number of pencils Sarah purchased: n = 12p

n = total number of pencils

p = number of packages

n depends on p, because the total number of pencils dependos on how many packages she will buy, so:

independent variable: p

dependent variable: n
