Lana71 [14]

P=100ft
H=135ft

We need base

Apply Pythagorean theorem

B²=H²-P²
B²=135²-100²
B²=18225-10000
B²=8225
B=90.697ft
B=90.7ft

Show all work to identify the discontinuity and zero of the function f of x equals 4 x over quantity x squared minus 16

Leto [7]

Answer:

Discontinuity of function occurs when x = 4 or x = -4

zero of function is when x=0

Step-by-step explanation:

We are given:

$f(x) = \frac{4x}{x^2 - 16}$

Discontinuity of the function occur when the denominator is equal to zero.

So, we need to find the values of x that makes the denominator zero.

The denominator is x^2 - 16

x^2 - 16 =0

x^2 = 16

x = ± 4

So, if the value of x = 4 or value of x=-4 then the function will be discontinuous.

Zero of the function i.e f(x)=0

So, Putting the function equal to zero and finding the value of x

$\frac{4(x)}{(x)^2 - 16}=0\\4x =0((x)^2 - 16)\\4x=0\\x=0$

So, zero of function is when x=0

The triangles are similar. Which side of triangle JGH corresponds to side PM of PMO? I think it’s JG.

nexus9112 [7]

It is JG! You must rotate the second triangle so both triangles are at the same angle. Then, look at the lines and find the corresponding line segment on the other triangle.
