CHECK THE COMPLETE QUESTION BELOW
Whitney deposits $9,000 for two years. She compares two different banks. State Banks will pay her 4.1% interest, compounded monthly. Kings Savings will pay her 4.01% interest, compounded continuously.Which bank pays higher interest? How much higher?
The Amount in the formula for compound interest is
A= P(1+r)^2
P = principal amount,
r = rate per periods,
t = number of periods,
To know the interest she got from the State bank, we say
P = $ 9000, r = 4.1% = 0.041, t = 2 years,
A= 9000(1+0.041)^2
A= 9000(1.041)^2
= 9767.74
Then interest earned = A - P
= 9767.74 - 9000
= $ 767.74
To know the interest she got from the State bank, we say
P = $ 9000, r = 4.01% = 0.0401, t = 2 years,
A= 9000(1+0.0401)^2
A= 9000(1.0401)^2
= 9751.53
Then interest earned = A - P
= 9767.74 - 9000
= $ 751.53
The difference between the two interest is ($ 767.74 - $ 751.53)
=$16.21
Hence state bank will have $16.21 higher interest
Answer:
(x+2)(x+6)
Step-by-step explanation:
that is the answer because math
A) We are told that at 2 hours, the velocity is 18 km/h and at 4 hours, the velocity is 4 km/h. Since we are relating two variables - let's give them names.
Let x = time and y = velocity. Since the velocity depends on the time (that is, the time influences velocity), this is a linear function. Any linear function can be written in slope intercept form as y = mx + b. The problem wants the situation in standard from of Ax + By = C, which can be found from slope intercept form.
So now we can make our line. Consider the ordered pairs of (2,18) and (4, 4) with them in (x, y) form. Finding the slope, m, between these points is as such:
m = y₂-y₁ / x₂-x₁
m = 4 - 18 / 4 - 2
m = -14 / 2 = -7.
Our slope is -7.
We take m = -7, x = 4, and y = 4 (it goes 4 km/h in 4 hrs) and use those three things to find the y-intercept.
y = mx + b
4 = -7 * 4 + b
4 = -28 + b
32 = b
So our equation of the line is y = -7x + 32. To put the equation into standard form, we need to place all the variables on one side of the equals sign, all the numbers on the other.
y = -7x + 32
7x + y = 32
In standard form, the equation for this situation is 7x + y = 32
***
To find out the velocity at 8 hours, we evaluate our function at x = 8. Either equation (standard form or slope intercept) works; we use standard form.
7x + y = 32
7*8 + y = 32
56 + y = 32
y = -24
At a time of eight hours, the bicycle is moving at -24 km/h.
