Answer:
The first three terms are [tex]3,6,11[/tex]
The 10th term is [tex]102[/tex]
Step-by-step explanation:
An ordered list of numbers is known as a sequence such that each number in the sequence is called a term.
The nth term is [tex]a_n=n^2+2[/tex].
To find the first 3 terms, put [tex]n=1,2,3[/tex]
[tex]a_1=1^2+2=1+2=3\\a_2=2^2+2=4+2=6\\a_3=3^2+2=9+2=11[/tex]
To find the 10th term, put [tex]n=10[/tex] in [tex]a_n=n^2+2[/tex]
[tex]a_{10} =(10)^2+2=100+2=102[/tex]
find the difference
1. 4-3/5
2.5-4/7
3.6-2/3
4.5-7/8
5.7-2/5
1) with 3/5 as a fraction one whole number can be written as 5/5
so you could rewrite 4 as 3 and 5/5 now subtract 3/5 and you are left with
3 and 2/5
2) one whole number can be written as 7/7
Now you have 4 and 7/7 minus 4/7 to get 4 and 3/7
Using the same steps for the rest:
3) 5 and 3/3 -2/3 = 5 and 1/3
4) 4 and 8/8 - 7/8 = 4 and 1/8
5) 6 and 5/5 - 2/5 = 6 and 3/5

the difference of products of a fraction with 5 whole 7/8 and 3 whole 3/4 is 11.Find the fraction.
Answer:
88/17
Step-by-step explanation:
5x · 7/8 - 3x · 3/4 = 11
35x/8 - 18x/8 = 17x/8
17x/8 = 11
17x = 88
x = 88/17
I don’t know how to do this help me
Answer:
The answer: ( 2 , -3 )
Step-by-step explanation:
equation (1): 5x + 2y = 4
equation (2): y = x - 5
step1: sub ( x-5 ) for y in equation 1:
5x + 2 ( x-5 ) = 4
step2: multiply 2 by the bracket:
5x + 2x - 10 =4
step3: add the x term together:
7x - 10 = 4
step4: add 10 for both sides:
7x = 14
step5: divide by 7 from both sides to get the value of x:
x = 2
step6: sub ( 2 ) for x in equation 2 :
y = x - 5
y = 2 - 5
step7: simplify to get the value of y:
y = -3
So the answer is:
x = 2 and y = -3
( 2 , -3 )

A shop owner increases some prices by 50%.
This is the same as:
choose one
multiplying the original price by 0.5, 1.5, 2.5 or 150?
The another way is same as;
Multiplying by 0.5 with original price.
Here,
A shop owner increases some prices by 50%.
We have to find another method to find same condition.
What is the percentage?
A relative value indicating hundredth parts of any quantity is called the percentage.
Now,
A shop owner increases some prices by 50%.
Let the original price is x.
Then, The increase value = x * 50% = x * 50/100 = 0.5x
Hence, To find the increase value we have to multiply by 0.5 with original price.

for every 5 red cars there are 8 black cars. If there are 24 more black cars than red cars how many total vehicles are there
Answer:
15 red cars + 24 black cars = 38
The total vehicles are 104.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
For every 5 red cars there are 8 black cars.
And, There are 24 more black cars than red cars.
Here, For every 5 red cars there are 8 black cars.
Hence, Number of red cars = 5x
Then, Number of red cars = 8x
And, There are 24 more black cars than red cars.
Hence, We get;
⇒ 24 + 5x = 8x
Solve for x as;
⇒ 24 = 8x - 5x
⇒ 24 = 3x
⇒ x = 8
Thus, Number of total vehicles = 5x + 8x
= 5×8 + 8×8
= 40 + 64
= 104

Answer:
I think b
Step-by-step explanation:
need a better quality photo
Answer:
B
Step-by-step explanation:
It's a little hard to see but I'm pretty sure it's B because we're looking for a graph that has a slope of -2 so it couldn't be A or D because they have positive slopes since they are pointing up. That leaves B and C. I can't really see but C doesn't look like it has a slope of -2, so I went with B because it has a y-intercept of 3 and looks like it has a slope of -2.

Tom and Katie are discussing the sequence: 22, 17, 12, 7, 2
Tom says the nth term rule is: -5n+17
Katie says the nth term rule is: 27-5n
A)Only Tom is correct
B)Only Katie is correct
C)They both are correct
D)Neither are correct
Answer:
B
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 17 - 22 = 12 - 17 = 7 - 12 = 2 - 7 = - 5
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 22 and d = - 5, then
[tex]a_{n}[/tex] = 22 - 5(n - 1) = 22 - 5n + 5 = 27 - 5n → B

If one event impacts the probability of a second event occurring, than which of the following is true?
The events are complements.
The events are dependent.
The events are independent.
Answer:
The events are dependent.
Step-by-step explanation:
Two events A and B are said to be independent if the fact that one event has occurred does not affect the probability that the other event will occur. If whether or not one event occurs does affect the probability that the other event will occur, then the two events are said to be dependent.
