Answer:
y=-(x+11)(x-23)
Step-by-step explanation:
y=-(x+11)(x-23)
use the x intercepts they give you, and make it the opposite i.e. if it positive, then make it negative if it is negative make it positive
i.e. -11 equals 11
thus (x+11)
then, the graph is concave down, so it is negative at the front

If two objects travel through space along two different curves, it's often important to know whether they will collide. (Will a missile hit its moving target? Will two aircraft collide?) The curves might intersect, but we need to know whether the objects are in the same position at the same time. Suppose the trajectories of two particles are given by the vector functions for t 0. Do the particles collide? If they collide find t. If not enter NONE.

What's the probability of the compound event for. A bag contains 4 red, 8 blue, 6 yellow and 2 green marbles. Maria selects a marble, puts it back and then selects a second marble. P (blue, red)
Answers
Given:
Number of red marbles = 4
Number of blue marbles = 8
Number of yellow marbles = 6
Number of green marbles = 2
To find:
The probability of getting a blue marble then a red marble, i.e., P(blue, red).
Solution:
Using the given information,
The total number of marbles = 4+8+6+2
= 20
Probability of getting a blue marble in first draw is
[tex]P(Blue)=\dfrac{\text{Number of blue marbles}}{\text{Total number of marbles}}[/tex]
[tex]P(Blue)=\dfrac{8}{20}[/tex]
[tex]P(Blue)=\dfrac{2}{5}[/tex]
Maria selects a marble, puts it back and then selects a second marble. It means the total number of marbles remains the same.
[tex]P(red)=\dfrac{\text{Number of red marbles}}{\text{Total number of marbles}}[/tex]
[tex]P(red)=\dfrac{4}{20}[/tex]
[tex]P(red)=\dfrac{1}{5}[/tex]
Now, the probability of getting a blue marble then a red marble is
[tex]P(blue,red)=\dfrac{2}{5}\times \dfrac{1}{5}[/tex]
[tex]P(blue,red)=\dfrac{2}{25}[/tex]
Therefore, the required probability P(blue, red) is [tex]\dfrac{2}{25}[/tex].

the total cost of kurts required textbooks this quarter is $342.50. optional textbooks cost a total of $65.25. whicg inequality shows the total cost C that kurt could pay for his textbooks?
Answers
Answer:
342.5 + 65.25 = C
407.75 = C
Step-by-step explanation:
Given that the total cost of Kurt's required textbooks this quarter is $ 342.50, while optional textbooks cost a total of $ 65.25, to determine which inequality shows the total cost C that Kurt could pay for his textbooks, the following mathematical reasoning must be performed:
Mandatory books + optional books = Cost
342.5 + 65.25 = C
407.75 = C
Thus, Kurt could pay a total cost of $ 407.75 for his textbooks this quarter.

1. 10
2. 14.1421
3. 8
4. 6.9282
Step-by-step explanation:
To find 1, you need to use tangent. Let's say the missing side is x. You need to use tan(45) = x/10 to be able to solve. If you don't know how to do that, you just need to multiply by 10 on both sides, that way the 10 cancels out and all you get is x. Tan(45) multiplied by 10 is 10.
Now, find 2 with sine. The equation is sin(45) = 10/x. First, you need to multiply both sides by x so you get 10 alone. Now, divide both sides by sin(45) to cancel out the left side and get the answer to 2. 10/sin(45) = 14.1421 (I don't know if you need to round).
To find 3, you need to use cosine. The equation would be cos(60) = 4/x. Again, multiply both sides by x to get 4 alone. Next, divide both sides by cos(60). 4/cos(60) is 8.
To find 4, you need to use sine again. The equation is sin(60) = x/8. Multiply both sides by 8, and there's your answer. 6.9282.

American League baseball teams play their games with the designated hitter rule, meaning that pitchers do not bat. The league believes that replacing the pitcher, traditionally a weak hitter, with another player in the batting order produces more runs and generates more interest among fans. Below are the average numbers of runs score in American League and National League stadiums for the first half of the 2001 season. **American:** 11.1, 10.8, 10.8, 10.3, 10.3, 10.1,10.0, 9.5, 9.4, 9.3, 9.2, 9.2, 9.0, 8.3 **National:** 14.0, 11.6, 10.4, 10.3, 10.2, 9.5, 9.5, 9.5, 9.5, 9.1, 8.8, 8.4, 8.3, 8.2, 8.1, 7.9 (a) Create two box plots to display this data and comment on what you see.

**National:**
14.0, 11.6, 10.4, 10.3, 10.2, 9.5, 9.5, 9.5, 9.5, 9.1, 8.8, 8.4, 8.3, 8.2, 8.1, 7.9
Kindly view attached picture for boxplot :
Using the relation :
Mean ± Zcritical * s/sqrt(n)
Zcritical at 95% = 1.96
National league :
Mean = 9.58125
Standard deviation = 1.5
9.58125 - 1.96 * 1.5/4 = 8.84625
9.58125 + 1.96 * 1.5/4 = 10.31625
(8.84625 ; 10.31625)
American League :
Mean = 9.807
Standard deviation = 0.805
9.807 - 1.96 * 0.805/sqrt(14)= 9.3853152
9.807 + 1.96 * 0.805/sqrt(14) = 10.228684

The multiplicative inverse of an expression is its reciprocal. It is the value that, when multiplied by the original, give a product of 1 (the multiplicative identity element).
Here, that is ...

The formula for compound interest is:
Where:
A = the future value of the investment (including interest)
P = the principal investment amount (the initial deposit amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per year
t = the number of years the money is invested for
If Josh invests $500 in a 5-year fixed interest savings bond that pays 5% per annum, how much will his entire investment be worth at the end of the term?
Answers
Answer:
Future value, A = $642
Step-by-step explanation:
Given the following data;
Principal = $500
Interest rate = 5% = 5/100 = 0.05
Time, t = 5 years
n = 365
To find the future value, we would use the compound interest formula;
[tex] A = P(1 + \frac{r}{n})^{nt}[/tex]
Where;
A is the future value.
P is the principal or starting amount.
r is annual interest rate.
n is the number of times the interest is compounded in a year.
t is the number of years for the compound interest.
Substituting into the equation, we have;
[tex] A = 500(1 + \frac{0.05}{365})^{365*5}[/tex]
[tex] A = 500(1 + 0.000137)^{1825}[/tex]
[tex] A = 500(1.000137)^{1825}[/tex]
[tex] A = 500*1.2840 [/tex]
Future value, A = $642
