if u substitute 3 for x, 3+4=7
you could also do 7-4 to get x which is 3 :)

Find the vertical and horizontal asympotote for (×-2) (×+3)/ (2×+2)

nekit [7.7K]

$\bf \cfrac{(x-2)(x+3)}{2x+2}\implies \cfrac{x^2+x-6}{2x+2}~~ \begin{array}{llll} \leftarrow \textit{2nd degree polynomial}\\ \leftarrow \textit{1st degree polynomial} \end{array} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{vertical asymptote}}{2x+2=0}\implies 2x=-2\implies x=-\cfrac{2}{2}\implies x=-1$

when the degree of the numerator is greater than the denominator's, then it has no horizontal asymptotes.

quick note:

when the degree of the numerator is 1 higher than the degree of the denominator, then it has an slant-asymptote, so this one has a slant-asymptote.

A population of deer inside a park has a carrying capacity of 200 and a growth rate of 3%. If the initial population is 80 deer,

otez555 [7]

Answer:

The population of deer at any given time = 200(e^0.03t) ÷ (1.5 + (e^0.03t))

Step-by-step explanation:

This is an example of logistic equation on population growth

carrying capacity, k = 200

Rate, r = 3% = 0.03

Initial Population, P1 = 80

P(t) =?

P(t) = (P1 (k)(e^rt)) ÷ (k- P1 + P1(e^rt))

P(t) = (80 (200)(e^0.03t)) ÷ (200 - 80 + 80(e^0.03t))

= (16000(e^0.03t)) ÷ (120 + 80(e^0.03t))

= 200(e^0.03t) ÷ (1.5 + (e^0.03t))

Last month, a basketball team scored 83, 84, 85, 87, 89, 88, 67, 79, and 81 points in their games. Which data value(s) are outli

Leto [7]

The data value that is an outlier is 67

<h3>How to determine the outlier?</h3>

The dataset is given as:

83, 84, 85, 87, 89, 88, 67, 79, and 81

To determine the outlier, we select the data values that are relatively far from others

In the above dataset, the data element 67 is far from other data values

Hence, the data value that is an outlier is 67
