What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.
Linear function is a function whose graph is a straight line
We are given that;
The function
Now,
we need to substitute x=3 into the function and simplify it. We get:
3(3)−1+(1+3)2
=8+16
≈2.83+16
=4
Therefore, by the given function answer will be 4.

Answer:
y's go
13, 6, 5, 4, -3
Step-by-step explanation:
well so you have the equation y = 5 - x^3
you are given the x for all of them
y = 5 - (-2)^3
5 - (-8) = 13
y = 5 - 0^3
5 - 0 = 5
y = 5 - 1^3
5 - 1 = 4
y = 5 - 2^3
5 - 8 = -3

A lottery offers one $900 prize, one $600 Prize, three $400 prizes, and four $100 prizes. One thousand tickets are sold at $5 each. Find the expectation if a person buys four tickets. Assume that the player's ticket is replaced after each draw and that the same ticket can win more than one prize. Round to two decimal places for currency problems.
Answer:
Expected value for 4 tickets = $ -7.6
Step-by-step explanation:
Given - A lottery offers one $900 prize, one $600 Prize, three $400 prizes, and four $100 prizes. One thousand tickets are sold at $5 each.
To find - Find the expectation if a person buys four tickets. Assume that the player's ticket is replaced after each draw and that the same ticket can win more than one prize. Round to two decimal places for currency problems.
Proof -
Given that,
A lottery offers
one $ 900 prize
one $ 600 prize
three $ 400 prizes
Four $ 100 prizes
And
One thousand tickets are sold at $ 5 each
Now,
If the person bought 1000 tickets then the prize he gets is
= 900 + 600 + 3×400 + 4×100
= 900 + 600 + 1200 + 400
= $3100
And
The cost of 1000 tickets = 5×1000 = $ 5000
Now,
Price 1 ticket = [tex]\frac{3100}{1000}[/tex] = $ 3.1
⇒Expectation of 1 ticket = $ 3.1 - 5 = $ -1.9 (Here $5 is price of 1 ticket)
⇒Expected value for 4 tickets = $ 4× -1.9 = $ -7.6
⇒Expected value for 4 tickets = $ -7.6
Solve for y
(4y+7)
(3y+5)
Answer:
24
Step-by-step explanation:
(4y + 7) + (3y + 5) = 180. (angle on a straight line =180)
4y + 7 + 3y + 5 =180
4y + 3y + 7 + 5 = 180
7y + 12 = 180
7y = 180 - 12
7y = 168
y = 168/7
y = 24

y=3/2x-9
I need to find the x-intercept and the y-intercept with work plsss
Hi there!
x-int: (6, 0)
y-int: (0, -9)
y = 3/2x - 9
Begin by finding the x-intercept. The x-intercept is located where y = 0, therefore:
0 = 3/2x - 9
Isolate for x by adding 9 to both sides:
9 = 3/2x
Divide both sides by 3/2x:
9 * 2/3 = x
x = 6. Thus, the x-intercept is at (6, 0).
Find the y-intercept by finding the y-value at which x = 0:
y = 3/2(0) - 9
y = -9. The y-intercept is at (0, -9).

calculate the number of terms in the following arithmetic sequence. 6;1;-4;-9....... -239
Answer:
50
Step-by-step explanation:
Given
first term (a) = 6
Common Difference (d) = 1 - 6 = - 5
Last term (tn )= - 239
Number of terms (n) = ?
We know
Tn = a + ( n - 1 ) d
- 239 = 6 + (n - 1) (-5)
- 239 = 6 - 5n + 5
- 239 = 11 - 5n
5n = 11 + 239
5n = 250
n = 250 / 5
n = 50
The number of terms is 50.
