Answer:
[tex]a_{n}[/tex] = 30 - 5n
Step-by-step explanation:
There is a common difference between consecutive terms, that is
20 - 25 = 15 - 20 = 15 - 20 = 10 - 15 = 5 - 10 = - 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 = 25 and d = - 5, thus
[tex]a_{n}[/tex] = 25 - 5(n - 1)
= 25 - 5n + 5
= 30 - 5n
2.1 If an event has a probability that is greater than 0.4, what does it mean?
2.2 What is meant when two events are said to be mutually exclusive?
Answer:
Step-by-step explanation:
1) i think for the first question any probability greater than 0.4 has more likelihood that it will happen
2) mutually exclusive events are ones that cannot occur at the same time as it's impossible e.g. a single coin toss cannot result in you getting heads and tails

Answer:
h = V/πr²h = 10 inchesStep-by-step explanation:
V = πr²h1. Solving for h:
V = πr²hπr²h = Vπr²h/πr² = V/πr²h = V/πr²2. Finding the height of given cylinder, using formula above:
V = 90π, r = 3 inches, h = ?h = V/πr²h = 90π/π3²h = 10 inches4. Lines 1 and 2 are parallel, and lines 3 and 4 are parallel.

What is the coordinate of the midpoint of DA?
D
Answer:
6
Step-by-step explanation:
Coordinate of point D = -6
Coordinate of point A = 18
The coordinate of the midpoint of DA = the coordinate of the point that is half the distance from D to A.
Distance of DA = |18 -(-6)| = |18 + 6| = 24
Midpoint = ½ the distance of DA = ½*24 = 12
Coordinate of the midpoint of DA = coordinate of D + 12 = -6 + 12 = 6
Or,
Coordinate of A - 12 = 18 - 12 = 6
Therefore, coordinate of the midpoint of DA = 6.

Evaluate the function f(x) = 7x - 8 at the given values of the independent variable and simplify.
a. f(7)
b. f(x + 5)
c. f(-x)
Answer:
Step-by-step explanation:
Given the function :
f(x) = 7x - 8
Evaluate the given values of the independent variable and simplify.
a. f(7)
b. f(x + 5)
c. f(-x)
A.) f(7)
f(7) = 7(7) - 8
= 49 - 8
= 41
B.) f(x + 5)
7(x + 5) - 8
7x + 35 - 8
7x - 27
C.) f(-x)
7(-x) - 8
-7x - 8
Study these equations:
f(x) = 2x - 4
g(x) = 3x + 1
What is h(x) = f(x)g(x)?
O h(x) = 6x2 – 10x - 4
O h(x) = 6x2 – 12x - 4
O h(x) = 6x2 + 2x - 4
O h(x) = 6x2 + 14x + 4
Answer:
A. h(x) = 6x2 – 10x – 4
Step-by-step explanation:
Got 100% on edge.
The value of h(x) is h(x) = 6x^2 -10x + 4
How to determine the composite function?The functions are given as:
f(x) = 2x - 4
g(x) = 3x + 1
So, we have:
h(x) = f(x)g(x)
This gives
h(x) = (2x - 4) * (3x+ 1)
Evaluate
h(x) = 6x^2 + 2x - 12x - 4
This gives
h(x) = 6x^2 -10x + 4
Hence, the value of h(x) is h(x) = 6x^2 -10x + 4

A garden table and
bench cost $897 combined. The garden table costs $47 more than the bench. What is the cost of the bench?
Answer:
472
Step-by-step explanation: First subtract the additional cost from the overall cost, than you find the value of the bench by dividing by 2, than add the additional cost to the price of the bench to find the total cost of the Garden Table.
897-47=850
850 divided by 2 = 425
425 + 47 = 472

Is(0,-2) a solution of x+y=6
Answer:
no
Step-by-step explanation:
x+y=6
Substitute the point into the equation and see if it is true
0 + -2 = 6
-2 =6
This is not true so the point is not a solution
Answer: No
Step-by-step explanation:
To see if (0.-2) is a solution of x+y=6, we can plug it in and solve.
0+(-2)=6 [add]
-2≠6
Since -2 does not equal 6, we know that (0,-2) is not a solution.

Answer:
Total variable costs for the summer at each price:
a. = $10,185
b. = $5,820
c. = $1,455
Step-by-step explanation:
a. 35 lawns per week x 12 weeks x $24.25 variable cost
= 35 * 12 * $24.25
= $10,185
b. 20 lawns per week x 12 weeks x $24.25 variable cost
= 20 * 12 * $24.25
= $5,820
c. 5 lawns per week x 12 weeks x $24.25 variable cost
= 5 * 12 * $24.25
= $1,455
d. The variable cost, as can be seen from above, changes based on the volume of activity or production. The number of lawns influenced the cost, since the other indexes are the same in each case.
The largest perfect square factor of 252 is _____
Answer:
18
Step-by-step explanation:
252 is a composite number. The exponents in the prime factorization are 2, 2, and 1. Adding one to each and multiplying we get (2 + 1)(2 + 1)(1 + 1) = 3 x 3 x 2 = 18. Therefore 252 has 18 factors.
