What is exponential growth and exponential decay?
Answer:
In exponential growth, the rate of growth is proportional to the quantity present. In other words, y′=ky. Systems that exhibit exponential growth have a constant doubling time, which is given by (ln2)/k. Systems that exhibit exponential decay have a constant half-life, which is given by (ln2)/k
Step-by-step explanation:
There is your answer good luck! - Alexsys
Answer:
In some cases with exponential functions, as the value of x increases, the value of y also increases. This is a direct relationship known as exponential growth. As the value of x increases, the value of y grows rapidly. ... This is an inverse relationship known as decay.

A line contains the points (6,-4) and (0,-2). What is the equation of the line?
Answer:
The equation of the line is:
[tex]y = -\frac{1}{3}x - 2[/tex]
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope and b is the y-intercept, that is, the value of y when x = 0.
(0,-2)
This means that the y-intercept is -2, that is, [tex]b = -2[/tex]. So
[tex]y = mx - 2[/tex]
Finding the slope:
When we have two points, the slope is given by the change in y divided by the change in x.
We have points (6,-4) and (0,-2).
Change in y: -2 - (-4) = -2 + 4 = 2
Change in x: 0 - 6 = -6
Slope: [tex]m = \frac{2}{-6} = -\frac{1}{3}[/tex]
So the equation of the line is:
[tex]y = -\frac{1}{3}x - 2[/tex]

Answer:
x ≈ 0.309906932381 or 4
Step-by-step explanation:
There are no algebraic methods of solving a mixed exponential and polynomial equation. The value of x can be found by guessing, or by other means such as trial and error or graphing.
Attached is a graph showing two solutions. x = 4 is the integer solution (2^4 = 4·4). The irrational solution is approximately x ≈ 0.309906932381. That precision is obtained by Newton's method iteration, easily done by a graphing calculator.

The weight of adult female panthers in one habitat area are normally distributed with a mean of 82 pounds and a standard deviation of 9.8 pounds. What percent of the panthers weigh less than 76 pounds?
Answer:
27.09% of the panthers weigh less than 76 pounds
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 82 pounds and a standard deviation of 9.8 pounds.
This means that [tex]\mu = 82, \sigma = 9.8[/tex]
What percent of the panthers weigh less than 76 pounds?
The proportion is the pvalue of Z when X = 76. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{76 - 82}{9.8}[/tex]
[tex]Z = -0.61[/tex]
[tex]Z = -0.61[/tex] has a pvalue of 0.2709
0.2709*100% = 27.09%
27.09% of the panthers weigh less than 76 pounds

The length of a swimming poollane
is 10 more than 2 times the width.
If the area is 300 square meters,
find the width of the lane. Write a
quadratic equation which can be
used to find x, the width of the
pool.
Answer:
x²+5x - 150 = 0
Step-by-step explanation:
Let the length be y and width be x
If the length of a swimming pool is 10 more than 2 times the width, then;
y = 2x+10 ...1
Since the Area is 300m²
A = xy
300 = xy .... 2
Substitute 1 into 2
300 = x(2x+10)
300 = 2x²+10x
Rearrange
2x²+10x - 300 = 0
Divide through by 2
x²+5x - 150 = 0
This gives the required quadratic expression

A theory predicts that the mean age of stars within a particular type of star cluster is 3.3 billion years, with a standard deviation of .4 billion years. (Their ages are approximately normally distributed.) You think the mean age is actually greater, and that this would lend support to an alternative theory about how the clusters were formed. You use a computer to randomly select the coordinates of 50 stars from the catalog of known stars of the type you're studying and you estimate their ages. You find that the mean age of stars in your sample is 3.4 billion years.

Triangle a: 44.7°
Triangle b: 30.5°
Triangle c: 67.4°
Triangle d: 56.6°
Step-by-step explanation:
Recall: SOHCAHTOA
a. Reference angle = [tex] \theta [/tex]
Opposite = 19
Hypotenuse = 27
Apply SOH:
[tex] sin(\theta) = \frac{Opp}{Hyp} [/tex]
[tex] sin(\theta) = \frac{19}{27} [/tex]
[tex] \theta = sin^{-1}(\frac{19}{27}) [/tex]
[tex] \theta = 44.7 degrees [/tex] (nearest tenth)
b. Reference angle = [tex] \theta [/tex]
Opposite = 33
Adjacent = 56
Apply TOA:
[tex] tan(\theta) = \frac{Opp}{Adj} [/tex]
[tex] tan(\theta) = \frac{33}{56} [/tex]
[tex] \theta = tan^{-1}(\frac{33}{56}) [/tex]
[tex] \theta = 30.5 degrees [/tex] (nearest tenth)
c. Reference angle = [tex] \theta [/tex]
Opposite = 12
Adjacent = 5
Apply TOA:
[tex] tan(\theta) = \frac{Opp}{Adj} [/tex]
[tex] tan(\theta) = \frac{12}{5} [/tex]
[tex] \theta = tan^{-1}(\frac{12}{5}) [/tex]
[tex] \theta = 67.4 degrees [/tex] (nearest tenth)
d. Reference angle = [tex] \theta [/tex]
Hypotenuse = 20
Adjacent = 11
Apply CAH:
[tex] cos(\theta) = \frac{Adj}{Hyp} [/tex]
[tex] cos(\theta) = \frac{11}{20} [/tex]
[tex] \theta = cos^{-1}(\frac{11}{20}) [/tex]
[tex] \theta = 56.6 degrees [/tex] (nearest tenth)

Find the amplitude and the period of the graphed function; please show work or steps.
Answers:
Amplitude = 2Period = 5pi/2===========================================
Explanation:
The lowest point occurs when y = -2. The highest point occurs when y = 2.
The vertical distance between the highs and lows is 4 units (since 2-(-2) = 2+2 = 4). This cuts in half to get 4/2 = 2.
The amplitude is 2. It measures the vertical distance from the midline to either the peaks or valleys.
-----------------------------
Note that this curve has two lowest points and one highest point shown. What we'll do is shift the graph over to the right so that each of those lowest points snap to a grid point. The lowest point on the left will move to where x = -pi, while the lowest point on the right snaps to x = 3pi/2. We'll keep each point at the same y coordinate.
The horizontal distance from x = -pi to x = 3pi/2 is
(3pi/2) - (-pi) = 3pi/2 + 2pi/2 = 5pi/2
This represents the horizontal distance from the left valley point to the right valley point. This is one full period of the curve. After we arrive at the right valley point, we repeat the process of going up and coming back down in this exact same fashion. The process is repeated forever to generate the cosine curve. The curve repeats itself every 5pi/2 units along the x axis.
Side note: any phase shift of a curve will have the same period as the original curve. This is why we're allowed to shift left or right to help find the period.
Constructed line PQ is the _______________ of line segment CD.
Answer:
Perpendicular bisector
Step-by-step explanation:
Construction done:
1). An arc is drawn from point O which intersects line 'l' at two points C and D.
2). From the points C and D two equal arcs on both the sides of the line 'l' have been drawn intersecting each other at points P and Q.
3). Points P and Q have been joined with the help of a straightedge.
Hence constructed line PQ is the PERPENDICULAR BISECTOR of the line segment CD.
