Answer:
Bob = 4500
Al = 6300
carlo = 7200
Step-by-step explanation:
the following equations can be derived from the question
A = B + 1800 equation 1 or A - B = 1800
C = 7200 = 2/3 (A + B) equation 2
where A = Al's score
B = Bob's score
C = Carlo's score
Make A + B the subject of the formula in equation 2
A + B = 10,800 equation 3
subtract equation 1 from 3
2B = 9000
B = 4500
Substitute for B in equation 1
A = 4500 + 1800 = 6300

a) You reach a maximum height of 45 feet
b) You will land 11.2 feet from the cannon
c) The barrel of the cannon is about 11 feet above the ground.
d)At a point 13 feet from the cannon, you begin to descend.
Q: You are shot out of a cannon at the fair. The equation y=-1/5 * (x+2) (x-28) models your flight path, where y is the height above the ground and x is the horizontal distance. Which of the following statements in the comments are true?
a) You reach a maximum height of 45 feet,
b) You will land 11.2 feet from the cannon,
c) The barrel of the cannon is about 11 feet above the ground.
d)At a point 13 feet from the cannon, you begin to descend.
A: When y = 0, x = 28
y’ = 0 at x = 13 where Y is max = 15^2 / 5 = 45
Hence a is true, b is false, c is false, d is false .

Given: α is an angle in the second quadrant, csc α = 25/7; β is an angle in the first quadrant, cos β = √2/2. The value of tan ( α - β ) = _____.
-3/17
29/17
-31/17
15/17
Answer:
-31/17
Step-by-step explanation:
csc²α-cot²α=1
cot²α=csc²α-1=(25/7)²-1=(625-49)/49=576/49
α is in 2nd quadrant so cotα is negative.
cot α=-√(576/49)=-24/7
tan α=-7/24
cos β=√2/2
sec β=2/√2=√2
sec²β-tan ²β=1
tan ²β=sec²β-1
tan²β=(√2)²-1=2-1=1
β is in 1st quadrant ,so tan β is positive.
tan β=1
[tex]tan (\alpha -\beta )=\frac{tan \alpha -tan \beta }{1+tan \alpha tan \beta } \\=\frac{\frac{-7}{24} -1}{1+(\frac{-7}{24}) (1)} \\=\frac{-7-24}{24-7} \\=\frac{-31}{17}[/tex]

The 4th term of a geometric sequence is 48, and the common ratio is 2. What is the first term of the sequence?
*There are no answer choices available on Kydor*
Thank you so much for your help!
Answer:
6
Step-by-step explanation:
[tex]nth \: term \: of \: geometric \: \\ sequence \: is \: given \: as : \\ a_n = a {r}^{n - 1} \\ (a = ?, \: \: r = 2)\\ \\ a_4 =48......(given) \\ \\ \therefore \: a {(2)}^{4 - 1} = 48 \\ \\ \therefore \: a {(2)}^{3} = 48\\ \\ \therefore \: 8a = 48 \\ \\ \therefore \: a = \frac{48}{8} \\ \\ \therefore \:a = 6[/tex]
Answer:
6
Step-by-step explanation:
geometric sequence is given as Tn=ar^n-1
where Tn is the last term,a is the first term, r is the common ratio, n is the nth term
hence 48=a2^(4-1)
48=a2^3
48=a8 (divide both by 8 to ramain with a)
6=a
therefore the first term is 6 .

Arthur, Kyle, and Tom are all on the baseball team. At the end of the season, they compared how many home runs each of them hit. Arthur noticed that if he doubled the number of home runs he hit and then subtracted 1, he would get the number of home runs Kyle hit. Tom noticed that if he subtracted 1 from the number of home runs he hit and then doubled that number, he would get the number of home runs Kyle hit. Write an expression representing the number of home runs Kyle hit in terms of the number of home runs Arthur hit, a. Enter your response in the first response box. Write an expression representing the number of home runs Kyle hit in terms of the number of home runs Tom hit, t.
Answer:
k = 2a - 1
k = 2(t - 1)
Step-by-step explanation:
Let :
Number of home runs Arthur hit = a
Number of home runs Kyle hit = k
Number of home runs Tom hit = t
Kyle's home runs, k in terms of Arthur's home run : Double the value of a ; then subtract 1
k = 2a - 1
Kyle's home runs in terms of Tom's home runs ;
Subtract 1 from t `
k = 2(t - 1)

Step-by-step explanation:
First we count the number of beans in total which is 20
Then we count the number of red beans which is 6
6/20 can be simplified to 3/10
Answer:
C) 3/10
Step-by-step explanation:
There are 6 red + 5 blue + 4 green + 5 black = 20 jelly beans in total
Since there are 6 red jelly beans, the probability of randomly selecting a red jelly bean is 6 red jelly beans / 20 total jelly beans = 6/20 = 3/10

Steve and Bill had a very successful day fishing for speckled trout. Together they caught 46 trout in one morning. Steve was proud that he caught 14 more fish than Bill.
How many speckled trout did each person catch?
Answer:
Number of trout caught by Bill = 16 trout
Number of trout caught by Steve = 30 trout
Step-by-step explanation:
Given:
Total number of trout caught = 46
Number of trout caught by Steve = Number of trout caught by Bill + 14
Find:
Number of trout caught by Steve
Number of trout caught by Bill
Computation:
Assume;
Number of trout caught by Bill = a
Number of trout caught by Steve = a + 14
So,
Number of trout caught by Steve + Number of trout caught by Bill = Total number of trout caught
a + a + 14 = 46
2a = 46 - 14
2a = 32
a = 16
Number of trout caught by Bill = 16 trout
Number of trout caught by Steve = a + 14
Number of trout caught by Steve = 16 + 14
Number of trout caught by Steve = 30 trout
Marcus measured the height, In Inches, y, of plants over the course of 3 weeks, The correlation coefficient between the number of days, x, and the height of the plants is 0.85. Which could be concluded based on the correlation coefficient of the data?
A. There is a strong relationship showing that as the number of days increases, the height of the plants increases.
B. There is a strong relationship showing that as the number of days Increases, the height of the plants decreases.
С. There is a weak relationship showing that as the number of days increases, the height of the plants increases,
D. There is a weak relationship showing that as the number of days increases, the height of the plants decreases,
Answer:
A) There is a strong relationship showing that as the number of days increases, the height of the plants increases.
Step-by-step explanation:
Because the correlation coefficient of 0.85 is very close to 1, there's going to be a strong, positive linear correlation between the two variables. Therefore, option A is correct.
There is a strong relationship showing that as the number of days increases, the height of the plants increases.
What is the correlation coefficient of the data?A correlation coefficient is a bivariate statistic when it summarizes the relationship between two variables, and it’s a multivariate statistic when you have more than two variables.
Marcus measured the height, In Inches, y, of plants over the course of 3 weeks, The correlation coefficient between the number of days, x, and the height of the plants is 0.85.
When the correlation coefficient is above 0.8, the correlation cofficeint is strong.
And the function is increasing.
So, there is a strong relationship showing that as the number of days increases, the height of the plants increases.
Hence, there is a strong relationship showing that as the number of days increases, the height of the plants increases.
