The function that gives the amount of money in dollars, J(t), in Jamie's account t years after the initial deposit is A = 627(1.00875)^{4t} (in dollars)
How to calculate compound interest's amount?If the initial amount (also called as principal amount) is P, and the interest rate is R% per unit time, and it is left for T unit of time for that compound interest, then the interest amount earned is given by:
[tex]CI = P(1 +\dfrac{R}{100})^T - P[/tex]
The final amount becomes:
[tex]A = CI + P\\A = P(1 +\dfrac{R}{100})^T[/tex]
For this case, we're given that:
Initial amount Jamie deposits = P = $627Rate of interest = 3.5% compounding quarterlyTime = t yearsRate of interest is compounding quarterly.
Each year has 4 quarters.
Rate of interest is usually annual rate of interest. Since compounding is done quarterly, let we express everything in quarter years.
Quarterly interest rate compounding quarterly = 3.5/4 = 0.875% = R%
t years has 4t quarters = T
Thus, we get the final amount in Jamie's account as
[tex]A = P\left(1 +\dfrac{R}{100}\right)^T\\\\A = 627 \left(1 +\dfrac{0.875}{100}\right)^{4t}\\\\A = 627(1.00875)^{4t} \: \rm \text{(in dollars)}[/tex]
Thus, the function that gives the amount of money in dollars, J(t), in Jamie's account t years after the initial deposit is [tex]A = 627(1.00875)^{4t}[/tex] (in dollars)

In rhombus ABCD shown below, AB=17 and AC=16 determine the length of BD without (hint , not with trigonometry)
Answer:
[tex]BD = 30[/tex]
Step-by-step explanation:
Given
[tex]AB = 17[/tex]
[tex]AC = 16[/tex]
See attachment
Required
Find BD
If AC = 16, then:
[tex]AO = 16/2[/tex] i.e. half the diagonal AC
[tex]AO = 8[/tex]
The diagonals of a rhombus are perpendicular.
This implies that we can apply Pythagoras theorem.
Using Pythagoras theorem on triangle AOB, we have:
[tex]AB^2 = AO^2 + OB^2[/tex]
[tex]17^2 = 8^2 + OB^2[/tex]
[tex]289 = 64 + OB^2[/tex]
Collect like terms
[tex]OB^2 = 289 - 64[/tex]
[tex]OB^2 = 225[/tex]
Take positive square roots of both sides
[tex]OB = 15[/tex]
To solve for BD, we use:
[tex]OB = \frac{BD}{2}[/tex] --- i.e. half the diagonal BD
[tex]BD = 2 * OB[/tex]
[tex]BD = 2 * 15[/tex]
[tex]BD = 30[/tex]

Andrew has a round trampoline with a diameter of 4 yards. What is the circumference of the trampoline?
You would use this formula for the problem...
(C=2πr) The circumference equals 2 multiplied by pi and radius.
In this problem it says diameter, but the diameter is just twice the length of the radius, so just multiply the radius by 2. Plugin your number.
C=2π(2) since 2 is half of 4, that's your radius.
Your answer is roughly C= 12.57.
You're welcome.

A community center rents thier hall for special events. They charge a fixed fee of $200 plus an hourly fee of $22.50. Lin has $300 to spend on renting the hall for a fundraiser white and solve an inequality that represents this situation
Answer
[tex]300 \geqslant 22.5x + 200[/tex]
Step-by-step explanation:
300 is less than or equal to 22.5x + 200
the budget is 300 so you can't go past that number. the appropriate inequality sign for this would be less than or equal to the following equation: $22.5 x (where x= number of hours) + the fixed fee of $200
don't include $ (or other units of measurements) in equations!!

Answer:A
Step-by-step explanation:
For positive acute angles AA and B,B, it is known that \cos A=\frac{24}{25}cosA= 25 24 and \sin B=\frac{11}{61}.SinB= 61 11 . Find the value of \sin(A+B)sin(A+B) in simplest form.
Answer:
684/1525
Step-by-step explanation:
Given
cosA = 24/25
SinB = 11/61
Sin(A+B) = SinAcosB + CosAsinB
Get SinA
Since
Cos A = adj/hyp
adj = 24
hyp = 25
opp² = 25² - 24²
opp² = 625 - 576
opp² = 49
opp = √49
opp = 7
sinA = opp/hyp
sinA = 7/25
Also if SinB = 11/61
opposite = 11
Hypotenuse = 61
adj² = 61² - 11²
adj² = 3,721 - 121
adj² = 3600
adj = √3600
adj = 60
Cos B = adj/hyp
CosB = 60/61
Sin(A+B) = SinAcosB + CosAsinB
Sin(A+B) = 7/25(60/61) + 24/25(11/61)
Sin(A+B) = 420/1,525 + 264/1,525
Sin(A+B) = 684/1525
QUICKK The Johnson family went to a socially distance movie and paid $30 for two adults and two children the modern family went to the same movie and paid 35 for two adults and three children what was the price of an adult ticket
Answer: adults = $10
Step-by-step explanation:
x = adults
y = children
2x + 2y = 30
2x + 3y = 35
Using the elimination method:
2x + 2y = 30
-2x - 3y = -35 (multiplied by -1, to give 2x -2x = 0)
Solve for y...
2y = 30
-3y = -35
Add together...
-y = -5
Multiply by -1 to give positive value for y...
y = $5
Plug into one of the original equation to find x...
2x + 10 = 30
2x = 20
x = $10
