Which of these statements describes the situation?-it will take less than 10 years to double the initial investment-it will take less than 20 years to triple the initial investment-it will take more than 15 years to double the investment-it will take more than 30 years to triple the initial investment
ANSWER
It will take less than 20 years to triple the investment.
EXPLANATION
We want to identify the statement that best describes the situation represented by the graph of the compound interest over time.
To do this, let us find at what point the compound amount doubles and triples.
Since the initial investment is $600, it implies that double this investment is $1200, and triple this investment is $1800.
Hence, we have to identify what happens at these points on the graph.
Notice that when y approaches $1200 on the vertical axis, x is greater than 10 and less than 15. It occurs at about x = 12 years.
Also, notice that when y approaches $1800 on the vertical axis, x is less than 20 years (also less than 30 years). It occurs at about x = 19 years.
Hence, the only correct statement that describes the situation is that it will take less than 20 years to triple the investment.
The correct answer is the second option.

What is the first step to solving the following equation?5x – 11 = 42
Answer:
add 11 on both sides
Step-by-step explanation:
to solve this, you want x alone on one side. To achieve this, you first add 11 on both sides, so you only have the 5x alone.
Second step then is something to get only one x on the left side ;-)
(divide both sides by 5)
Answer:
the first step is to get the x term by itself on one side

I need some help with this I don’t understand how I would do it can I have some help
from the graph shown in the question,
we could deduce that:
x = -3,
which means x + 3 = y,
we can also deduce that x = 4,
which means that, x - 4 = y
so, the eqaution of the graph could be
y = (x - 2) (x + 3) (x - 4)
since the graph is a cubic graph
therefore the correct option is B

Using long division divide y cubed + 0y squared minus 1 by y +4
Given the expression:
[tex]\frac{y^3+0y^2-1}{y+4}[/tex]Step 1:
Divide the leading term of the dividend by the leading term of the divisor. Multiply the result by the divisor and subtract the final result from the dividend as follows:
[tex]\begin{gathered} \frac{y^3}{y}=y^2 \\ \\ \\ y^2(y+4)=y^3+4y^2 \\ \\ \\ (y^3-1)-(y^3+4y^2)=-4y^2-1 \end{gathered}[/tex]Step 2: Divide the leading term of the obtained remainder by the leading term of the divisor, multiply it by the divisor, and subtract the remainder from the obtained result:
[tex]\begin{gathered} \frac{-4y^2}{y}=-4y \\ \\ \\ -4y(y+4)=-4y^2-16y \\ \\ \\ (-4y^2-1)-(-4y^2-16y)=16y-1 \end{gathered}[/tex]Step 3: Divide the leading term of the obtained remainder by the leading term of the divisor, multiply it by the divisor, and subtract the remainder from the obtained result:
[tex]\begin{gathered} \frac{16y}{y}=16 \\ \\ \\ 16(y+4)=16y+64 \\ \\ \\ (16y-1)-(16y+64)=-65 \end{gathered}[/tex]Since the degree of the remainder is less than the degree of the divisor, we would stop.
Therefore, the answer is:

A 17-1b bag of Zollipops is $120.00. Connecticut 3 sales tax is 6.35% and Missouri's is 4.225%. How much more sales tax does a customer in Connecticut pay for the bag than one in Missouri?
step 1
Find out how much is the sales tax in Connecticut
we have
6.35%=6.35/100=0.0635
Multiply by $120.00
120.00*(0.0635)=$7.62
step 2
Find out how much is the sales tax in Missouri
we have
4.225%=4.225/100=0.04225
Multiply by $120.00
120.00*(0.04225)=$5.07
step 3
Find the difference
so
7.62-5.07=$2.55
therefore

Make use of structure. For rectangle ABCD, two vertices are A(-2, 3) and B(4, 6). Find the slopes of BC, CD, and DA. Explain your answer.
We are given a rectangle ABCD
A(-2, 3)
B(4, 6)
We are asked to find the slopes of sides BC, CD, and DA.
Let me first draw a rectangle to better understand the problem
Recall that the slope is given by
[tex]m=\frac{y_2−y_1}{ x_2−x_1}[/tex][tex]\text{where}(x_1,y_1)=(-2,3)\text{and}(x_2,y_2)=(4,6)[/tex]So the slope of side AB is
[tex]m_{AB}=\frac{6-3}{4-(-2)}=\frac{3}{4+2}=\frac{3}{6}=\frac{1}{2}=0.5[/tex]The sides BC and DA are perpenducluar to the side AB.
So their slopes will be
[tex]m_{BC}=m_{DA}=\frac{1}{-m_{AB}}[/tex]Substituting the value of slope of AB
[tex]m_{BC}=m_{DA}=\frac{1}{-0.5}=-2[/tex]The side CD is parallel to the side AB.
Parallel sides have equal slopes so
[tex]m_{CD}=m_{AB}=\frac{1}{2}[/tex]Therefore, the slopes of the rectangle ABCD are
[tex]\begin{gathered} m_{AB}=m_{CD}=\frac{1}{2} \\ m_{BC}=m_{DA}=-2 \end{gathered}[/tex]Taylor wants four different pairs of sneakers, but can only afford to buy three of thepairs? How many sets of three pairs of sneakers can she possibly choose?
We have a set of four pairs of sneakers {A; B; C; D} and want to know how many sub-sets of three pairs of sneakers can be made with this.
To calculate that, we just need to have in mind that, for the first pair which Taylor will choose, there are four possibilities. After Taylor chooses the first pair, will be three possibilities for the second pair. And, for the third pair, we will have only the las two possibilities.
So, to gete the total number of sets of three pairs of sneakers that can be made, we just multiply the three correspondent possibilities for each choose: 4*3*2 = 24
Let f(x) = -2x^2– 7 and g(x) = 4x – 7.(fog)(x) =(gof)(x) =(fog)(1) =
Part 1.
The compositon fog is given by
[tex](f\circ g)(x)=-2(4x-7)^2-7[/tex]which gives
[tex]\begin{gathered} (f\circ g)(x)=-2(16x^2-56x+49)^{}-7 \\ (f\circ g)(x)=-32x^2+112x-98^{}-7 \\ (f\circ g)(x)=-32x^2+112x-105 \end{gathered}[/tex]Then, the answer is:
[tex](f\circ g)(x)=-32x^2+112x-105[/tex]Part 2.
The composition gof is given by
[tex](g\circ f)(x)=4(-2x^2-7)-7[/tex]Then, the answer is:
[tex](g\circ f)(x)=-8x^2-35[/tex]Part 3.
In this case, we need to substitute x=1 into the answer of Part 1, that is,
[tex]\begin{gathered} (f\circ g)(1)=-32(1)^2+112(1)-105 \\ (f\circ g)(1)=-32^{}+112-105 \end{gathered}[/tex]Therefore, the answer is:
[tex](f\circ g)(1)=-25[/tex]Below, the function f(x) =3x-2 f(x)=3x-2 and the function f(x)= 3x+1f(x)=3x+1 are graphed. Compare and contrast the lines. What is similar about the equations and graphs? What is different?
You have the lines associated to the following functions:
f(x) = 3x - 2
f(x) = 3x + 1
The general equation of a line is given by:
y = mx + b
where m is the slope and b the y-intercept.
By comparing the given functions with the general form, you can notice that the slope of the lines are equal (m = 3) and the y-intercept are different, b=-2 and
b = 1.
Due to the slopes are the same you have two parallel lines.
A circle has a diameter of 300m. What is his circumference using pi?
To find the circumference using π = 3.14, we can proceed as follows:
1. The formula to find the circumference of a circle is:
[tex]C=2\pi r\Rightarrow D=2r\Rightarrow C=D\pi[/tex]2. That is, given the diameter, we can use it directly into the answer, since twice the value of the radius is the diameter of the circle:
[tex]C=300m\cdot3.14=942m[/tex]If we find the radius as:
[tex]D=2r\Rightarrow r=\frac{D}{2}=\frac{300m}{2}=150m[/tex]And If we use the next formula:
[tex]C=2\pi r=2\cdot3.14\cdot150m=942m[/tex]As we can see, in both cases, we found that the value for the circumference is equal to 942 meters (if we use π = 3.14).
In summary, the circumference of a circle that has a diameter of 300 meters is equal to 942 meters (C = 942m) (using π = 3.14).
