Consider the standard form of an exponential function:
\(y=a(b)^x\)
How does changing the base number (inside the parentheses) change your graph?
Answers
Answer:
Step-by-step explanation:
Challenge 1
We have exponential decline if 0 b 1. As you move from left to right, the curve will get less steep.
If b is greater than 1, exponential growth is present, and the curve slopes upward from left to right.
Examples include exponential decline (y = 2(0.5)x) and exponential growth (y = 2(1.2)x).
Remember that b cannot be negative.
===========================================
Challenge 2
In the general template provided, enter x = 0.
y = a(b)^x
y = a(b)^0
y = a(1) (1)
y = a
When x = 0 is plugged in, the result is y = a.
The curve is therefore on the point (0,a). The y intercept appears here. It is the point when the curve veers off the y axis. The y intercept is altered if the value of "a" is altered.

Step-by-step explanation:
To find the answer you do, 72+36+x=180, as angles of triangle add up to 180°.
You add 72 and 36 together and get 108. Then you do 180-108 which give you 72. Since a triangle is equal to 180.

What is linear equation?A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept. Occasionally, the above is called a "linear equation of two variables," where y and x are the variables.
The equation ,-2x +3y = 6
the y intercept is obtained when x = 0
-2(0) + 3y = 6
3y = 6
y = 6/3
y = 2.
The x intercept is obtained when y = 0
-2x = 6
x = 6/-2
x = -3
therefore the y and x intercept for the graph are 2 and -3 respectively.
For equation x+4y = 8
when x= 0
4y = 8
y = 8/4
y = 2
when y = 0
x = 8
therefore the y and x intercept are 2 and 8

U R A GOOD FRIEND!
Step-by-step explanation:
A manufacturer determines that the cost of making a computer component is $2.232323. Write the repeating decimal cost as a fraction and as a mixed number.
Answers
Answer:
\(\frac{221}{99}\), which as a mixed number is \(2\frac{23}{99}\)
Step-by-step explanation:
Let's say n = 2.232323... (our repeating decimal. In order to write our decimal number as a fraction, we need to find some way to get rid of the repeating decimal. We can do that by multiplying our number by 100:
100n = 100*2.232323... = 223.232323...
Now, we can set up a system of equations and subtract n from 100n:
\(100n=223.232323...\\n=2.232323...\\(100n-n)=223.232323...-2.232323...\\99n=221\\n=\frac{221}{99}\)
When we subtracted the two equations, we ended up eliminating the repeating decimal and we were able to solve for n in fraction form. The improper fraction is 221/99
We are also asked to write this as a mixed number. We know that 99*2 is 198. 221 - 198 is 23, which means 221/99 is 2 with a remainder of 23. We can re-write this as a fraction to get the following:
\(2\frac{23}{99}\)
The repeating decimal cost $2.232323 can be written as the fraction 221 / 99 and as the mixed number 2 23/99.
Given data:
To write the repeating decimal cost $2.232323 as a fraction:
Let x = 2.232323...
Multiply both sides of the equation by 100 to shift the decimal point two places to the right:
100x = 223.232323...
Subtract the original equation (x) from the shifted equation (100x):
100x - x = 223.232323... - 2.232323...
99x = 221
Divide both sides of the equation by 99 to solve for x:
x = 221 / 99
Now, simplify the fraction 221 / 99:
221 / 99 = 221 / (3 * 3 * 11)
= (13 * 17) / (3 * 3 * 11)
= (13 / 3) * (17 / 11)
So, the repeating decimal cost $2.232323 can be written as the fraction 221 / 99.
Now, express the fraction 221 / 99 as a mixed number:
Divide 221 by 99:
221 ÷ 99 = 2 with a remainder of 23
Therefore, the mixed number representation is 2 23/99
Hence, the repeating decimal cost $2.232323 can be written as the fraction 221 / 99 and as the mixed number 2 23/99.

y = 0
And x is equal to 1
x is equal to one because we substitute the x in the equation starting from 1 or -1 however you want to go and substitute the x to get what 6. So like you see how I solved the equation using 1 as x you get (1, 0)

Step-by-step explanation:
First, find the slope using the points (3, 2) and (-1, -1):
Slope = m = y2 -y1 / x2 -x1 = -1 -2 / -1 -3 = -3/-4 = 3/4
Find the y-intercept, b, by substituting x = -1, y = -1 and m = ¾ in y = mx + b.
-1 = ¾(-1) + b
-1 = -¾ + b
Add ¾ to both sides
-1 + ¾ = b
(-4 + 3)/4 = b
-¼ = b
Substitute m = ¾ and b = -¼ in y = mx + b.
The equation would be:

You have to look at both x and y and it’s power. You have to look for the lowest power for x and y. For y as you can see that the lowest power is 2. As for x it can be either power of 3 or even 2. When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.
When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.
