Answer:

3.605 ft is the answer.

Step-by-step explanation:

Applying Pythagoras theorem,

a^2 + b^2 = c^2

2^2 + 3^2 = c^2

4 + 9 = c^2

13 = c^2

3.605 = c

therefore, the answer is 3.605.

How to find the common denominator of two numbers?

Snowcat [4.5K]

Find the number that both can be divided by i.e. the common denominator of 56/8 is 8 because 56 is divisible by 8 and 8 is also divisible by 8.
so by finding the common denominator and dividing the fraction, the equation would look like this: 7/1

The diameter of a cookie is 2 inches. If pico’s 3.14, what is the area of the cookie, rounded to the nearest 10th?

Amanda [17]

For this case we must find the area of the cookie, knowing that it has a circular shape. By definition, the area of a circle is given by:

$A = \pi * r ^ 2$

Where:

r: It is the radius of the circle

According to the data we have:

$r = \frac {2} {2} = 1 \ in$

Thus, the area of the cookie is:

$A = \pi * (1) ^ 1$

We have $\pi = 3.14$

$A = 3.14 * 1\\A = 3.14$

We round:

$A = 3.1$

Thus, the area of the cookie is $3.1 \ in ^ 2$

Answer:

$3.1 \ in ^ 2$

Which function is represented by the graph below?

Ymorist [56]

Answer:

$f(x)=2^x$

Step-by-step explanation:

Exponential function:

$f(x)=a(b^x)+c$

Step 1. Find a, y-intercept

Step 2. Find b, slope

Step 3. Find c, horizontal asymptote

a = 1

m = (y₂ - y₁)/(x₂ - x₁)

m = (3 - 1)/(1 - 0) = 2/1

b = 2

c = 0

$f(x)=1(2^x)+0\\f(x)=2^x$
