The roof of a barn rises vertically 2.5 meters through the horizontal distance of 10 meters. What is the pitch (slope) of the ro

Lesechka [4]

Answer:

The pitch (slope) of the roof is $0.25$ or $25\%$

Step-by-step explanation:

we know that

The formula to calculate the slope is equal to

$m=\frac{y2-y1}{x2-x1}$

where

In this problem we have

${y2-y1}=2.5\ m$ -----> is the vertical distance (rises)

${x2-x1}=10\ m$ -----> is the horizontal distance (run)

substitute the values

$m=\frac{2.5}{10}=0.25$

convert to percentage form

$0.25*100=25\%$

<u>Corrected Question</u>

Is the function given by:

$f(x)=\left\{\begin{array}{ccc}\frac{1}{4}x+1 &x\leq 4\\4x-11&x>4\end{array}\right$

continuous at x=4? Why or why not? Choose the correct answer below.

Answer:

(D) Yes, f(x) is continuous at x = 4 because $Lim_{x \to 4}f(x)=f(4)$

Step-by-step explanation:

Given the function:

$f(x)=\left\{\begin{array}{ccc}\frac{1}{4}x+1 &x\leq 4\\4x-11&x>4\end{array}\right$

A function to be continuous at some value c in its domain if the following condition holds:

f(c) exists and is defined.

$Lim_{x \to c}$ f(x)$ exists.

$f(c)=Lim_{x \to c}$ f(x)$

At x=4

$f(4)=\dfrac{1}{4}*4+1=2$

$Lim_{x \to 4}f(x)=2$

Therefore: $Lim_{x \to 4}f(x)=f(4)=2$

By the above, the function satisfies the condition for continuity.

The correct option is D.

The next term in 3, 12, 48, 192,768,...

geniusboy [140]

3 * 4 = 12

12 * 4 = 48

48 * 4 = 192

192 * 4 = 768

The next number in the sequence is the previous number multiplied by 4:

The next number would be 768 x 4 = 3072

Describe the relationship between 2/3 of 3/4 and 3/4 of 2/3?

nexus9112 [7]

The relationship between 2/3 of 3/4 and 3/4 of 2/3 is that the product will equal the same because in multiplication, it doesn't matter what order you put the numbers in because it will equal the same product.
