Answer
The y-intercept = 2
Explanation
The slope and y-intercept form of the equation of a straight line is given as
y = mx + b
where
y = y-coordinate of a point on the line.
m = slope of the line.
x = x-coordinate of the point on the line whose y-coordinate is y.
b = y-intercept of the line.
So, we just have to write the given equation in this form and the y-intercept will become apparent.
x + 4y = 8
4y = -x + 8
Divide through by 4
(4y/4) = (-x/4) + (8/4)
y = -0.25x + 2
Comparing this with y = mx + b
We can see that
b = y-intercept = 2

Suppose you found a CD that pays 2.1% interest compounded monthly for 6 years. If you deposit $12,000 now, how much will you have in the account in 6 years? (Rounded to the nearest cent.) What was the interest earned? Now suppose that you would like to have $20,000 in the account in 6 years. How much would you need to deposit now?
The interest earned is the difference between the initial amount that was deposited in the bank and the amount that is in the account after six years.
[tex]\begin{gathered} A\text{ = 12000\lparen1+}\frac{2.1\%}{12})^{6*12} \\ This\text{ is from the compound interest formula.} \\ A\text{ = 13609.89} \end{gathered}[/tex]Amount in the account: $13609.89
The interest earned is therefore: 13609.89 - 12000 = $1609.89

Determine whether triangle DEF with vertices D(6, -6), E(39, -12), and F(24, 18) isscalene (no congruent sides), isosceles (two congruent sides), or equilateral (threecongruent sides).
We have three given points. We need to graph them, and then find the distances between them.
We need to remember that we can classify the triangles according to their sides:
1. A triangle with three congruent sides is an equilateral triangle.
2. A triangle with two congruent sides is an isosceles triangle.
3. A triangle with no congruent sides is a scalene triangle.
Additionally, we know that a segment is congruent to other when it has the same size as the other.
Then we can graph the three points as follows:
Now, we need to find the distances between the sides of the triangle using the distance formula as follows:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]This is the distance formula for points (x1, y1) and (x2, y2).
Finding the distance between points D and EThe coordinates for the two points are D(6, -6) and E(39,-12), and we can label them as follows:
• (x1, y1) = (6, -6) and (x2, y2) = (39, -12)
Then we have:
[tex]\begin{gathered} d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\ \\ d=\sqrt{(39-6)^2+(-12-(-6))^2} \\ \\ d=\sqrt{(33)^2+(-12+6)^2} \\ \\ d=\sqrt{33^2+(-6)^2}=\sqrt{1089+36}=\sqrt{1125} \\ \\ d_{DE}=\sqrt{1125}\approx33.5410196625 \end{gathered}[/tex]Therefore, the distance between points D and E is √1125.
And we need to repeat the same steps to find the other distances.
Finding the distance between points E and FWe can proceed similarly as before:
The coordinates of the points are E(39, -12) and F(24, 18)
• (x1, y1) = (39, -12)
,• (x2, y2) = (24, 18)
Then we have:
[tex]\begin{gathered} d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\ \\ d=\sqrt{(24-39)^2+(18-(-12))^2} \\ \\ d=\sqrt{(-15)^2+(18+12)^2}=\sqrt{(-15)^2+(30)^2}=\sqrt{225+900} \\ \\ d_{EF}=\sqrt{1125}\approx33.5410196625 \end{gathered}[/tex]Then the distance between points E and F is √1125.
Finding the distance between F and D
The coordinates of the points are F(24, 18) and D(6, -6)
• (x1, y1) = (24, 18) and (x2, y2) = (6, -6)
Then we have:
[tex]\begin{gathered} d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\ \\ d=\sqrt{(6-24)^2+(-6-18)^2}=\sqrt{(-18)^2+(-24)^2}=\sqrt{324+576} \\ \\ d=\sqrt{900}=30 \\ \\ d_{FD}=30 \end{gathered}[/tex]Now, we have the following measures for each of the sides of the triangle:
[tex]\begin{gathered} \begin{equation*} d_{DE}=\sqrt{1125}\approx33.5410196625 \end{equation*} \\ \\ d_{EF}=\sqrt{1125}\approx33.5410196625 \\ \\ d_{FD}=30 \end{gathered}[/tex]Therefore, in summary, according to the results, we have two sides that are congruent (they have the same size). Therefore, the triangle DEF is an isosceles triangle.

A loan of $43,000 is made at 5.25% interest, compounded annually. After how many years will the amount due reach $64,000 or more? (Use the calculator provided if necessary.)Write the smallest possible whole number answer.
Answer:
8 years
Explanation:
For a compound interest loan compounded annually, the amount due after t years is calculated using the formula:
[tex]A(t)=P(1+r)^t\text{ where }\begin{cases}P={Loan\;Amount} \\ {r=Annual\;Interest\;Rate}\end{cases}[/tex]We want to find when the amount due will reach $64,000 or more.

I am thinking of a number. It has two digits. When I reverse the digits and then add the new number to the original number I get 33. What is the number?
Let x and y be the digits.
The original number has two digits that means that one is the tens and the other the ones, in this case let x be the tens and y the ones, then we have the number:
[tex]10x+y[/tex]if we reverse it this means that the y become the tens and x becomes the ones then we have the number:
[tex]10y+x[/tex]And if we add them the result is 33, then we have the equation:
[tex]\begin{gathered} (10x+y)+(10y+x)=33 \\ 11x+11y=33 \\ x+y=3 \\ y=3-x \end{gathered}[/tex]This means that y has to be 3-x. Now, since we both numbers to have two digits x can't be zero nor 3. Then has to be 1 or 2.
If x=1 then y=2 and the original number is 12.
If x=2 then y=1 and the original number is 21.
Notice how in both cases we get the other one when reversed, therefore the numbers we are looking for are 12 and 21.

If the vector is pointing in the opposite direction of [-4,3], we can say it is pointing in the same direction of the vector [4,-3]. We just flipped the direction of the vector by changing the sign of the components.
We have now a vector that is pointing in the same direction of the vector we are looking for. Let's find the length of that vector to see how much it has to be scaled, or if it does not need to be scaled.
The length of the vector is calculated as the square root of the sum of the square of its components:
[tex]\text{Length}=\sqrt[]{x^2+y^2}[/tex]Then, the length of the vector is:
[tex]\begin{gathered} \text{Length}=\sqrt[]{4^2+(-3)^2}=\sqrt[]{16+9}=\sqrt[]{25} \\ \\ \text{Length}=5 \end{gathered}[/tex]Then the length of the vector [4,-3], which is pointing opposite to the vector [-4,3], happens to have a length of 5, then, that is the vector we were looking for. There is no need to scale it.
Then, the components of the vector are 4 and -3. [4,-3]

A ball is thrown in the air from a platform. The path of the ball can be modeled by the function h(t)=-16 t^{2}+32t+4 where h(t) is the height in feet and t is the time in seconds.How long does the ball take to reach its maximum height?
Answer:
1 second
Explanation:
The equation that models the path of the ball is given below:
[tex]h\mleft(t\mright)=-16t^2+32t+4[/tex]To determine how long it takes the ball takes to reach its maximum height, we find the equation of the line of symmetry.
[tex]\begin{gathered} t=-\frac{b}{2a},a=-16,b=32 \\ t=-\frac{32}{2(-16)} \\ =-\frac{32}{-32} \\ t=1 \end{gathered}[/tex]Thus, we see that it takes the ball 1 second to reach its maximum height.

You pick a card at random put it back and then pick another card at random what is the probability of picking a number greater than 5 and then picking a 5 right and then picking a 5 write your answer as a percentage
You have four cards numbered 4, 5, 6, and 7.
Step 1
To calculate the probability of picking a card at random, and that this card has a number greater than 5, you have to divide the number of successes by the number of possible outcomes.
Successes: You want to pick a card with a number greater than 5, there are only two cards that meet this condition, the card numbered 6 and the card numbered 7, so for this scenario, there are 2 successes.
Total outcomes: The number of outcomes is equal to the total number of cards you can pick from, in this case, the total number of outcomes is 4.
Next, calculate the probability of picking a card with a number greater than 5:
[tex]\begin{gathered} P(X>5)=\frac{nºsuccesses}{Total\text{ }outcomes} \\ P(X>5)=\frac{2}{4} \\ P(X>5)=\frac{1}{2}=0.5 \end{gathered}[/tex]The probability of picking a card with a number greater than 5 is 0.5.
Step 2
Next, you put the card back and pick another one at random.
You have to calculate the probability that this time you will pick the card numbered 5.
To calculate this probability you have to divide the number of successes by the total number of outcomes.
Successes: there is only one card with the number 5, so the number of successes is 1.
Total outcomes: since the first card that was drawn was returned to the deck, the total number of outcomes is still 4.
Calculate the probability of drawing a 5:
[tex]\begin{gathered} P(X=5)=\frac{nºsuccesses}{Total\text{ }outcomes} \\ P(X=5)=\frac{1}{5}=0.2 \end{gathered}[/tex]The probability of drawing a 5 is 0.2.
Finally, the probability that you have to determine is to "draw a card with a number greater than 5 and then pick a 5"
The event described is the intersection of both events "drawing a card greater than 5" and "picking a 5". Since the first card was returned to the deck before drawing the second card, both events are independent, which means that the probability of their intersection is equal to the product of the individual probabilities of the events, so that:
[tex]P(X>5\cap X=5)=P(X>5)*P(X=5)=0.5*0.2=0.1[/tex]The probability is 0.1.
Multiply the result by 100 to express it as a percentage:
[tex]0.1*100=10\%[/tex]The probability of picking a number greater than 5 and then picking a 5 is 10%.
