rewona [7]

Answer:

D

Step-by-step explanation:

when flipping and turning the second triangle, so that it is oriented as the first triangle (we see DE corresponds to AB - consider at what corner point the right angle is : at A and at D; DF corresponds to AC, EF corresponds to BC), we see immediately that BCA is the same sequence of corners as the corresponding EFD.

What is the value of x in the question 5/8=x/52

skad [1K]

X= 32.5

You have to change the denominators (8 and 52) to be the same (52).

52/8=6.5

So 6.5 is your scale factor.

Simply multiply your numerator (5) by 6.5 to get 32.6

<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.
