Daniel puts $80,000 in an account that earns .6% interest compounded annually how much interest does he earn after 15 years

Daniel can earn $7510 interest he get after 15 years of investment.
What is compound interest?Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest.
Here, principal = $80,000
Time = 15 years
Rate of Interest = 0.6% compounded annually
We know that,
[tex]A = P(1+i)^n[/tex]
[tex]A = 80000(1 + 0.006)^{15}[/tex]
[tex]A = 80000 X 1.006^{15}[/tex]
A = 80000 X 1.094
A = 87,510.41
Interest = Amount - Principal
= 87510 - 80000
= $ 7,510
Thus, Daniel can earn $7510 interest he get after 15 years of investment.

A. The difference of -p and -q
B. The product of -p and -q
C. The sum of -p and -q
D. The quotient of -p and -q
Answers
The coefficient of the x-term in the trinomial is C. The sum of -p and -q, which is -p - q. therefore ,option C. The sum of -p and -q, which is -p - q is correct.
When the factors of a trinomial are (x - p) and (x - q), you can find the coefficient of the x-term in the trinomial by multiplying these factors together and paying attention to the x-term.
The product of (x - p) and (x - q) is:
(x - p)(x - q) = x^2 - qx - px + pq
Now, notice that the coefficient of the x-term is the sum of the terms that contain 'x,' which are -qx and -px:
Coefficient of the x-term = -qx - px
This can be factored as:
Coefficient of the x-term = x*(-q - p)
So, the coefficient of the x-term in the trinomial is:
C. The sum of -p and -q, which is -p - q

What is this number? +1.25 E -19
Answers
By definition we have to:
The use of this notation is based on base powers 10.
A number written in scientific notation follows the following pattern:
[tex]m * 10 ^ e [/tex]
The number m is called "mantissa" and e the "order of magnitude"
For this case we have:
[tex]m = 1.25 e = -19[/tex]
Using the definition, we have that the number can be rewritten as:
[tex]+1.25 E -19 = 1.25 * 10 ^ {-19} [/tex]
[tex] 1.25 * 10 ^ {-19} = 0.000,000,000,000,000,000,125 [/tex]
Answer:
an expression that this number is:
[tex] 1.25 * 10 ^ {-19} = 0.000,000,000,000,000,000,125[/tex]
Final answer:
The notation '+1.25 E -19' represents the number in scientific notation, equivalent to 1.25 × 10^-19.
Explanation:
The notation '+1.25 E -19' is likely intended to be represented the number 1.25 × 10-19, which is an example of scientific notation.
The Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in the decimal form. In this context, 'E' stands for exponent, indicating that the number should be multiplied by 10 and raised to the power of -19.
Therefore, +1.25 E -19 means the number is positive and equals 0.000000000000000000125.

Bryan's puppy has been gaining weight for the last year. The graph shows data about the puppy's weight over time.
Answers
I hope this helped! :-)
Answer:
Option 2. 25 pounds
Step-by-step explanation:
As per graph weight gain of Bryan's puppy is represented by a linear function which is a straight line.
Therefore equation of the line will be y = mx + c
to calculate the value of m we will take two points (endpoints) on the line (0, 0) and (50, 6)
So m = (50-0)/(6-0) = 50/6 = 8.33
since this passes through (0, 0) so c = 0
Equation will be y = 8.33x
Now we have to get the value of y (weigh of puppy) at x = 3.
y = 8.33×3 = 24.99 ≈ 25 lb.

For this case, the first thing to do is find the slope of the line:
m = (18 3/4) / (5)
m = (18.75) / (5)
m = 3.75
m = 3 3/4

ODYSSEYx varies inversely as v, and x = 48 when v = 8. Find x when v = 64.
Question 17 options:
x = 8
x = 6
x = 64
x = 48
Answers
Answer: the correct option is (B) x = 6.
Step-by-step explanation: Given that x varies inversely as v and x = 48 when v = 8.
We are to find the value of x when v = 64.
Since x varies inversely as v, so we have
[tex]x\propto\dfrac{1}{v}\\\\\\\Rightarrow x=k\dfrac{1}{v}~~~~~~~~~~~~~~~~~~[\textup{where k is the constant of proportionality}][/tex]
When x = 48 and v = 8, then, we get
[tex]48=\dfrac{k}{8}\\\\\Rightarrow k=48\times8\\\\\Rightarrow k=384.[/tex]
So,
[tex]x=\dfrac{384}{v}~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
Therefore, when v = 64, then from equation (i), we get
[tex]x=\dfrac{384}{64}=6.[/tex]
Thus, the required value of x is 6.
Option (B) is CORRECT.
