A social networking site has an estimate 5000 members.This number is expected to increase 80% each month. Which function and graph model the number of members in thousands over time in months?
Answer:
y = 5(1.8)^x
Step-by-step explanation:
the formula for an exponential equation is y = a(b)^x
the a in this case is the starting number which is 5000
y = 5000(b)^x
the b is the percentage in decimal form
0.8 BUT it is an increase so we add 1
1.8
y = 5000(1.8)^x
because the graph is in thousands we can make 5000 into 5

Given
In your notebook, set up the following addition using a vertical format and find the sum of the given polynomials.
Vertical Format:Write each polynomial below their like term and then combine it.
First expression: [tex]\rm 2mn+4n^2[/tex]
Second Expression: [tex]\rm 5m^2-7mn[/tex]
Now, we will add vertically. If the variable part of the term is the same then it would be like a term.
By using the vertical format the addition is;
[tex]\rm 2mn+4n^2+0m^2[/tex]
[tex]\rm 5m^2-7mn+0n^2[/tex]
Now, combine their coefficient and write the variable as same.
[tex]\rm -5mn+4n^2+5m^2[/tex]
We can rearrange the term according to options.
[tex]\rm 5m^2+4n^2-5mn[/tex]
Hence, the sum of the polynomial is [tex]\rm 5m^2+4n^2-5mn[/tex].

Delyth borrows £3450 from a family member who charge her 2% per year simple interest. She pays all the money back in one payment after 1 year 3 months. How much interest does Delyth pay?
simple interest = principal × rate × time in years
= 3450 × (2/100) × ( 1.25)
= 3450 × 0.02 × 1.25
= 86.25
If Delyth borrowed £3450 for a year and three months at a simple interest rate of 2% per year, she would be responsible for paying interest of £86.25.
What is simple interest?Simple interest is the amount of interest charged on a specific principal amount at a specific interest rate. Compound interest, on the other hand, is the interest that is computed using both the principal and the interest that has accumulated over the preceding period.
First, we must determine how much interest Delyth would pay if she borrowed £3450 for a year and three months at a simple interest rate of 2% per year.
Since interest is charged annually, we may begin by figuring out the yearly interest rate. The interest rate yearly would be:
2% per year = 0.02 per year
Next, we can calculate the interest owed for 1 year and 3 months. Since there are 12 months in a year, 1 year and 3 months would be 15 months. Therefore, the interest owed would be:
Interest = Principal x Rate x Time
Interest = £3450 x 0.02 x (15/12)
Interest = £86.25
So, Delyth would owe £86.25 in interest for borrowing £3450 at a simple interest rate of 2% per year for 1 year and 3 months.

Find the Value of X.
Answer:
x =6
Step-by-step explanation:
angles opposite of each other in a parallelogram are congruent
∠C and ∠A are opposite from each other and it appears that they are in a parallelogram so we can assume that ∠C = ∠A
∠A = 13x - 25 and ∠C = 9x - 1
Hence 13x - 25 = 9x - 1
13x - 25 = 9x - 1
add 25 to both sides
13x = 9x + 24
subtract 9x from both sides
4x = 24
divide both sides by 4
x = 6

Andrew researched the depreciation of cars and found that the value of the car he just bought halved every 5 years. Andrew purchased the car for $20,000 and he wants to find how many years it will take for the value of the car to reduce to $15,000. He wrote the equation 20000(5)^t/2=15000, and plans to solve for t. What change(s) should Andrew make to the equation to find the value of t in the above scenario? Use the half-life decay formula, m(t) = m o (1/2)^t/h, to answer the question.
A. t/2 should be replaced with 2t
B. 15000 and 20000 should be interchanged
C. 5 should be replaced with 1/2, and t/2 should be replaced with t/5
D. 5 should be replaced with 1/2, and t/2 should be replaced with 5t
Answer:
C. 5 should be replaced with 1/2, and t/2 should be replaced with t/5
Step-by-step explanation:
The problem statement tells you the half-life of the car is 5 years. Using the value h = 5 in the given equation, you have ...
m(t) = m₀(1/2)^(t/5)
The problem statement tells us the initial value of the car is $20,000, so we have ...
m₀ = 20000
m(t) = 20000(1/2)^(t/5)
Since Andrew wants the value of t when m(t) = 15000, his equation would read ...
15000 =20000(1/2)^(t/5) . . . equation for finding when the value is 15000
__
The equation Andrew proposes to solve is ...
20000(5)^(t/2) = 15000
In order to make his equation look like the the one above, the changes should be ...
5 should be replaced with 1/2, and t/2 should be replaced with t/5.
_____
Additional comment
The equation can be solved as follows:
15000/20000 = (1/2)^(t/5)
log(3/4) = (t/5)log(1/2) . . . . take the log of both sides, simplify the fraction
t = 5log(3/4)/log(1/2) . . . . divide by the coefficient of t
t ≈ 2.08
Andrew's car will have a value of about $15,000 after 2 years and 1 month.

Name a decimal between 3.14 and 3.15
I ALREADY GOT THE ANSWERS
BUT I WANT TO KNOW HOW TO GET THEM
(please explain it to me in a simple and detailed way)
Answer:
3.141
Step-by-step explanation:
To find a decimal between 3.14 and 3.15, we have to look at the ten-thousandths place. 3.14 becomes 3.140 and 3.15 becomes 3.150. The 3.1 at the front is the same, so we keep it. Look at the 40 and 50. Name a number between those two. For example, 41. Put that number behind the 3.1 to get the final answer. In my example, the answer was 3.141.

[tex]3(4x-5)-4x+1=-6[/tex]
Answer:
[tex]x=1[/tex]
Step-by-step explanation:
Expand the brackets by multiplying each term in the bracket by the expression outside the bracket:
[tex]3(4x-5)-4x+1=-6[/tex]
⇒ [tex]12x-15-4x+1=-6[/tex]
Gather like terms and combine:
⇒ [tex]12x-4x+1-15=-6[/tex]
⇒ [tex]8x-14=-6[/tex]
Add 14 to each side of the equation:
⇒ [tex]8x-14+14=-6+14[/tex]
⇒ [tex]8x=8[/tex]
Divide both sides by 8:
⇒ [tex]8x \div8=8\div8[/tex]
⇒ [tex]x=1[/tex]
Given that : 3(4x-5)-4x+1 = -6
⇒ 12x-15-4x+1 = -6
⇒ (12x-4x)+(1-15) = -6
⇒ 8x+ −14 = −6
⇒ 8x = -6+14
⇒ 8x = 8
⇒ x = 8÷8
⇒ x = 1
So, value of x is 1

A customer purchased 9 avocados at the same price each. The customer had $46 to spend on groceries. After purchasing the avocados, the customer was left with $27.19. How much did each avocado cost?
Answer:
each avocado cost = $2.09
Step-by-step explanation:
He spent : $46 - $27.19 = $18.81
so lets the cost of each be x
9 * x = $18.81
x = $18.81 / 9
x = $2.09
