Answers
[tex]10=2d[/tex]
Given:
The sum of the first three terms of a sequence Is 42.
The fourth term is 24.
To find:
The u₁ and the common difference
Step-by-step explanation:
nth term of a sequence is
[tex]u_n=u_1+(n-1)d[/tex]
where, u₁ is first term and d is common difference.
4th term is 24.
[tex]u_4=u_1+(4-1)d[/tex]
[tex]24=u_1+3d[/tex] ...(i)
Sum of nth term of an AP is
[tex]S_n=\dfrac{n}{2}[2u_1+(n-1)d][/tex]
Sum of first three terms is 42.
[tex]S_3=\dfrac{3}{2}[2u_1+(3-1)d][/tex]
[tex]42=\dfrac{3}{2}[2u_1+2d][/tex]
Divide both sides by 3.
[tex]14=u_1+d[/tex] ...(ii)
On subtract (ii) from (i), we get
[tex]10=2d[/tex]
[tex]5=d[/tex]
Put d=5 in equation (ii).
[tex]14=u_1+5[/tex]
[tex]14-5=u_1[/tex]
[tex]9=u_1[/tex]
Therefore, the first term is [tex]u_1=9[/tex] and common difference is [tex]d=5[/tex] .

expand and simplify 3(2x+1)+2(x+4)
Answers
Answer:
8x+11
Step-by-step explanation:
1. 6x+3+2x+8
2. 8x+11
Answer:
8x + 11
Step-by-step explanation:
3(2x+1)+2(x+4)
distribute the 3 & 2 within the parentheses. first, multiply 3 and 2x, then multiply 3 and 1 to get 6x + 3. next, multiply 2 and x, then multiply 2 and 4 to get 2x + 8. this gives you:
6x + 3 + 2x + 8
then add like terms (6x + 2x and 3 + 8) to get your simplified final answer:
8x + 11
Suppose g(x) = 3 + 5x.

9514 1404 393
Answer:
4
Step-by-step explanation:
Substitute the given value for g(x) and solve the 2-step equation for x.
g(x) = 3 + 5x
23 = 3 +5x
20 = 5x . . . . . . subtract 3
4 = x . . . . . . . . divide by 5
The value of x is 4 when g(x) is 23.
?!?can someone tell me how to solve for domain and range on a graph!!!
Answers
Answer:
The domain is all of the x values for which the function has a y value and visa versa for the range. So the domain is the minimum x value to the maximum x value and the range is from the minimum y value to the maximum y value. Filled in circles include the point its on and open circles do not. You can show this difference using parentheses and brackets. brackets include the point, parentheses.

Solution,
Given; x^3-7x^2-x+7=0
Using factor theorem,
we have,
i)x^3-7x^2-x+7=0
let's check whether 1 is the factor of given equation or not by replacing the value of x by one..
or, 1^3-7.1^2-1+7=0
or, 1-7-1+7=0(.°. Cancellation of +1&-1 and +7&-7 in equation)
.°.0=0
which proves that 1 is one of the factor of x
therefore(x-1) is a factor of x^3-7x^2-x+7=0.
Now,
Expanding the x^3-7x^2-x+7=0 to get (x-1) as a factor...
ii)x^3-7x^2-x+7=0
or,x^3-x^2-6x^2+6x-7x+7
or,x^2(x-1) - 6x(x-1) - 7(x-1) = 0
or,(x-1) (x^2-6x-7)w = 0
or,,(x-1) (x^2-(7-1)x-7) =0
or,,(x-1) (x^2-7x + x -7) =0
or,(x-1) [x(x-7)+1(x-7)] = 0
or,(x-1) (x+1) (x-7) = 0
Either,
i) x - 1=0
.°.x = 1
And,
ii)x + 1 = 0
.°. x = -1
Or,
iii) x - 7 = 0
.°.x =7
Hence, the required value of x are -1 ,+1 & 7.

Phil Dunphy, a real estate agent, is considering whether he should list an unusual $451,299 house for sale. If he lists it, he will need to spend $3,925 in advertising, staging, and fresh cookies. The current owner has given Phil 6 months to sell the house. If he sells it, he will receive a commission of $20,283. If he is unable to sell the house, he will lose the listing and his expenses. Phil estimates the probability of selling this house in 6 months to be 37%. What is the expected profit on this listing.
Answers
Answer:
The expected profit on the listing is $5031.96
Step-by-step explanation:
Given that:
The probability of selling the house in 6 months is p = 0.37
The probability of not selling the house = 1 - 0.37 = 0.63
Suppose Y represents the profit on the listing,
Then: the expected profit on the listing can be computed as:
E(X) = ($20283* 0.37) - ($3925*0.63)
E(X) = $7504.71 - $2472.75
E(X) = $5031.96
Thus, the expected profit on the listing is $5031.96
The expected profit on the listing is $5031.96.
Calculation of the expected profit:Since
The probability of selling the house in 6 months is p = 0.37
The probability of not selling the house = 1 - 0.37 = 0.63
here Y means the profit on the listing,
So, the expected profit is
E(X) = ($20283* 0.37) - ($3925*0.63)
E(X) = $7504.71 - $2472.75
E(X) = $5031.96
Thus, the expected profit on the listing is $5031.96.

Roberto Clemente, born in Puerto Rico, became the first Latino baseball player to be inducted in the National Baseball Hall of Fame in 1973. He held many records including reaching 3,000 career hits. During that game, the umpire briefly stopped the game to give the ball to Clemente, who tossed it from second base to the first base coach. If the first base coach was standing 3 feet behind first base and Clemente was standing on second base, which is 90 feet from first base, which expression describes the distance between Clemente and the first base coach?
Answers
Answer:
93ftStep-by-step explanation:
Kindly find a simple sketch of a baseball pitch, the circle with a dot inside represents the first base coach(don't mind my drawing please I will improve).
So, from the diagram, we can see that the expression that describes the distance and the first base coach is
y=90+3
y=93
so the distance between Roberto Clemente and the first base coach is 93ft

Find the value of a and b
Answers
Answer: a = 40 degrees and b = 104 degrees
Step-by-step explanation:
Since a is directly across from 40 degrees those are vote equal. Now that we know a is 40 we also have b which lies on a straight line, meaning that it is a part of 180 degrees. We also have a and a 36 degree angle on that line. Since we know a is 40 we can add angle a and 36 to get 76 degrees. Now that we know part of the 180 degrees is 76, we subtract that from 180 to get angle b, meaning that b=106.
