There is a 50/50 chance to get heads or tails on the coin.
1. f(x)=8/1+3e^(-0.7x)
to get f(-3) we substitute the value and solve the equation as follows:
f(-3)=8/1+3e^(-0.7*3)
f(-3)=8.36737
which can also be written as:
f(-3)-8.36737=0
2. f(x)=20/1+9e^(3x)
to get the y-intercept we let x=0, hence we shall have:
f(0)=20/1+9e^(3*0)
f(0)=20+9*1
f(0)=20+9
f(0)=29
the y-intercept is at point (0,29)
3. f(x)=24/1+3e^(-1.3x)
Given that the expression above has no denominator, then the domain of the expression is all real numbers then the expression has not vertical asymptote.The same applies for horizontal asymptote and the oblique.
4. f(x)=15/1+4e^(-0.2x)
The graph is not increasing at any point, this means that it does not have a point of maximum growth.
5. f(x)=24/1+3e^(-1.3x)
The graph of the function is a decay graph, this means that there is no point in which the graph is increasing hence there's not growth rate.

5:
Distribute the Negative Sign:
= 3x^2+2x−3+−1(4x^2−8x+23)
= 3x^2+2x+−3+−1(4x^2)+−1(−8x)+(−1)(23)
= 3x^2+2x+−3+−4x^2+8x+−23
Combine Like Terms:
= 3x^2+2x+−3+−4x^2+8x+−23
= (3x^2+−4x^2)+(2x+8x)+(−3+−23)
= −x^2+10x+−26
Answer:
−x^2+10x−26
6: Distribute the Negative Sign:
= −13n^2−3n−6n^4+−1(13n^2+11n−2n^4)
= −13n^2+−3n+−6n^4+−1(13n^2)+−1(11n)+−1(−2n^4)
= −13n^2+−3n+−6n^4+−13n^2+−11n+2n^4
Combine Like Terms:
= −13n^2+−3n+−6n^4+−13n^2+−11n+2n^4
= (−6n^4+2n^4)+(−13n^2+−13n^2)+(−3n+−11n)
= −4n^4+−26n^2+−14n
Answer:
=−4n^4−26n^2−14n
7: and in math means to add
Combine Like Terms:
=4y^3+−8y+−y^3+5

9: answer is −8y
i had this in my notes from a while ago on my laptop so please see the image on how to solve this!
i hope this helps a lot!
Answer:
1980 yards
Step-by-step explanation:
We need to convert 1 1/8 miles into yards. For doing so we can conclude the following and use the information gathered:
1 mile = 1760 yards.
1/8 mile = 220 yards
In that case, we will add the two shown above together to find the total as well as our answer.
1760 + 220 = 1980
Thusly, there are
yards in 1 1/8 miles.
Hope this helps!
We will start by making each of the solutions a binomial which is equal to zero.
First solution:
x = 5
x - 5 = 0
Second solution:
x = -2
x + 2 = 0
Then we can multiply the two together using FOIL.
0 = (x - 5)(x + 2)
0 = x^2 - 5x + 2x - 10
0 = x^2 - 3x - 10
Since solutions (colutions as you like to call them) are found at f(x) = 0, the 0 can be replaced with f(x).
f(x) = x^2 - 3x - 10
