Adrian invested $790 in an account paying an interest rate of 6.9% compounded continuously. Assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $2,550?
Answer:17
Step-by-step explanation:
trust me its right, no cap
As per compound interest, it would take 17 years for the value of the account to reach $2,550
What is the compound interest?If the invested amount is 'P', the rate of interest is r%, and the time of investment is 'n' years, then the compound interest after mentioned duration is = P[1 - [tex]e^{rn}[/tex]]
Given, the invested amount (P) = $790.
Rate of interest (r) = 6.9% = 0.069.
Let, the amount is invested for 'n' years.
The value of the amount after 'n' years = $2550.
Now, as per compound interest:
A = P. [tex]e^{rn}[/tex]
⇒ 2550 = 790 [tex]e^{(0.069n)}[/tex]
⇒ [tex]e^{(0.069n)}[/tex] = (2550 ÷ 790)
⇒ [tex]e^{(0.069n)}[/tex] = 3.23
⇒ 0.069n = 1.172
⇒ n = 17

Arun's family took a road trip to Niagara Falls. Arun fell asleep 69% of the way through the trip. If Arun fell asleep after they had traveled 690 miles, what was the total length of the trip?
Answer:
69% × 690 =
(69 ÷ 100) × 690 =
(69 × 690) ÷ 100 =

Which inequality is represented by this graph?
A. 0>x
B.x>0
C. 0>_x
D.x>_0
Answer:
B. X > 0
Step-by-step explanation:
The dot it at 0, but is not filled in, so that means that it is not equal to.
The arrow is pointing to terms greater than 0 which can be described as (X). Since X is greater than 0, and not equal to 0, we get B as our answer.

Answer:
4 ft by 8 ft
Step-by-step explanation:
Answer:
D. 4ft by 10ft
Step-by-step explanation:
Since each square represents 4 feet and the door is 2 blocks plus a bit up it can't be 8 ft since 8ft would only be 2 blocks exactly, this also rules out B since 12 ft would need to be 3 blocks high. this leaves A and D. The third square is only half of a normal square which means its half of 4, 2. You add this to 8 to get 10.

Solve the inequality. 5(x + 1) – 10 ≥ 2x + 3(x + 2)
The solution of the inequality 5(x + 1) - 10 ≥ 2x + 3(2x + 2) is x ≤ - 16/3.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
Given, Inequality is 5(x + 1) - 10 ≥ 2x + 3(2x + 2).
5x + 5 - 10 ≥ 2x + 6x + 6.
5x + 5 - 10 ≥ 8x + 6.
5x - 8x ≥ 10 + 6.

Answer:
[tex]\displaystyle \log_7\frac{1}{81}\approx -2.2[/tex]
Step-by-step explanation:
We want to find:
[tex]\displaystyle \log_7{\frac{1}{81}}[/tex]
First, using the quotient rule:
[tex]\displaystyle \log_b\frac{a}{c}=\log_b a-\log_b{c}[/tex]
We can rewrite our expression as:
[tex]=\log_7 1-\log_7 81[/tex]
The logarithm of 1 is always 0. Therefore:
[tex]=-\log_781[/tex]
We can rewrite this as:
[tex]=-\log_7 9\cdot 9[/tex]
Using the product rule:
[tex]\log_b ac=\log_ba+\log_bc[/tex]
This is equivalent to:

Consider the standard form of an exponential function:
y = a (b)^x
1. How does changing the base number (inside the parentheses) change your graph? (10 points)
2. How does changing the number outside the parentheses change your graph? (10 points)
3. Create three new exponential equations to represent Alison, Cindy, and Javier. (30 points)
Alison loves social media and likes for her posts to be shared as much as possible while Cindy and Javier prefer for their posts to stay amongst their friends primarily.
I have number one please help with 2 and 3.
Answer:
2. If we plug in X = 0 into our problem ( Y = A(B)^X ) I would get Y = A which drastically changes the initial value, the Y-intercept, and the point on the graph. The point changes to (0,a) which becomes the new Y-intercept.
3. Cindy and Javier would be ln(x) and x^(1/2) as they will grow somewhat fast at first and then die out.
While Alison would be 1/(1+e^-x) representing an s curve showing a lot of growth and later evening out.
Step-by-step explanation:
The answer to part [2] and [3] are given above.
What is a mathematical function? What is an exponential function? Differentiate between equation and expression? exponential function : An exponential equation is given by -y = A(B)ˣ
function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is the standard form of an exponential function -
y = a (b)^x
[2] - Changing the number outside the parenthesis will determine the amplitude scaling of the graph of (A)ˣ. For -
a > 1 (Magnitude will increase)
a < 1 (Magnitude will decrease)
a = 0 (Magnitude will become zero)
[3] - For Alison, we can write the expression as -
y{A} = 5000(1000)ˣ
For Cindy and Javier, we can write -
y{C} = (2)ˣ
y{J} = (3)ˣ

find the value of x in the angle
Answer:
The answer would be B
Step-by-step explanation:
Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle. If you are working with equilateral triangles, divide 180 by three to find the value of X.
