M=(y2-y1)/(x2-x1)

you can find y2, x2, y1, and x1 by picking any numbers that goes through the line segment.

Hope it helped!! :)

Given the functions k(x) = 2x2 − 5 and p(x) = x − 3, find (k ∘ p)(x). (k ∘ p)(x) = 2x2 − 6x 4 (k ∘ p)(x) = 2x2 − 12x 13 (k ∘ p)(

$(k \circ p)(x)=k(p(x))=k(x-3) \\ \\ =2(x-3)^2-5 \\ \\ =2(x^2 - 6x+9)-5 \\ \\ =\boxed{2x^2 - 12x+13}$

Where is the removable discontinuity of f(x)=x+5/x^2+3x-10 located?

mario62 [17]

We are looking to find the point where the curve discontinued

Step 1: Factorise both numerator and denominator (if possible)
$\frac{x+5}{ x^{2} +3x-10}= \frac{(x+5)}{(x+5)(x-2)}$

Step 2: Recognise the common factor, which is $(x+5)$

Step 3: Equate the common factor to 0
$x+5=0$
$x=-5$

Answer: -5

1. What is the perimeter of the figure below. Simplify.<br> 4x^3-5x 2x^3+6x 6x^3+x

____ [38]

Answer:

$12x^3+2x$

Step-by-step explanation:

The perimeter of a polygon is equal to the sum of its sides.

The sides in the triangle shown have lengths $2x^3+6x$ , $4x^3-5x$ , and $6x^3+x$ in no specific order.

Since its perimeter is given by the sum of its sides, the perimeter is equal to:

$2x^3+6x+4x^3-5x+6x^3+x$

Combine like terms:

$\boxed{12x^3+2x}$

Answer:

Reminder that is this form a(b)^x where a > 0

When b > 0 but < 1 that is a decay function

When b > 1 than its a growth function

Step-by-step explanation:

So following this you can figure out the answer

g(x)=0.3(x)

this is neither since there is no exponent (linear)

H=72(56)^t

this is growth since b = 56

A=(43)^t

this is growth since b = 43 ("a" is understood as "1")

H=5.9(0.82)^t

this is decay since b = 0.82

y=0.8(3.6)^t

this is growth since b = 3.6

f(t)=0.72(15)^t

this is growth since b = 14

A=49(8)^t

this is growth since b = 8
