Isaac invested $1,800 in an account paying an interest rate of 4.7% compounded continuously. Assuming no deposits or withdrawals are made, how much money, to the nearest hundred dollars, would be in the account after 15 years?
Answer:
First, convert R as a percent to r as a decimal
r = R/100
r = 4.7/100
r = 0.047 rate per year,
Then solve for A,
[tex]A = P\cdot e^{rt}\\\\A= 1800 \cdot (2.71828)^{(.047)(15)}, \ where \ e = 2.71828\\A = 3642.92[/tex]
The amount he receives after 15years $3,642.92
If a rectangular. Prism. Has 5cm. 10cm on one side and 4cm on the. Other. What is the volume of the rectangle?
Answer: [tex]200\ cm^3[/tex]
Step-by-step explanation:
Given
The dimension of the rectangular prism is
[tex]l=5\ cm\\w=10\ cm\\h=4\ cm[/tex]
The volume of the prism is given by [tex]V=l\times w\times h[/tex]
[tex]\Rightarrow V=5\times 10\times 4\\\Rightarrow V=200\ cm^3[/tex]
Therefore, the volume of the prism is [tex]200\ cm^3[/tex].

How do you Write a problem in Standard Form?
Answer:
Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 × 103 = 4000
Step-by-step explanation:
First, Switch sides,
y-y^1=m\left(x-x^1)
Second, apply the rule a^1=a
y^1=y
m(x-x^1)=y-y
Third, add similar elements: y-y=0,
m(x-x^1)=0
Fourth, using the Zero Factor Principle: If ab=0 then a=0 or b=0
x-x^1=0
Finally, simplify,
0=0

Which polynomial function has zeros at -3, 0, and 4?
f(x) = (x + 3)(x2 + 4)
f(x) = (x2 - 3)(x - 4)
f(x) = x(x + 3)(x - 4)
f(x) = x(x - 3)(x + 4)
Answer:
If 5 is zero then (x - 5) is a factor.
Only 4. has this factor.

Solve for x.
[tex] {x}^{2} - 13x + 12 = 0[/tex]
Answer:
Solution given:
[tex] {x}^{2} - 13x + 12 = 0[/tex]
doing middle term factorization
x²-12x-x+12=
x(x-12)-1(x-12)=0
(x-12)(x-1)=0
either
x=12
or
x=1
value of x is 1 or 12.

Four chairs and two tables cost £218.
Six chairs and seven tables cost £587.
Find the total cost of buying twenty chairs and five tables.
Answer:
x = cost of a chair = £22
y = cost of a table = £65
£765
Step-by-step explanation:
Let
x = cost of a chair
y = cost of a table
4x + 2y = 218 (1)
6x + 7y = 587 (2)
Multiply (1) by 6 and (2) by 4
24x + 12y = 1,308 (3)
24x + 28y = 2,348 (4)
Subtract (3) from (4) to eliminate x
28y - 12y = 2,348 - 1,308
16y = 1,040
y = 1,040/16
y = 65
Substitute y = 65 into (1)
4x + 2y = 218 (1)
4x + 2(65) = 218
4x + 130 = 218
4x = 218 - 130
4x = 88
x = 88/4
x = 22
x = cost of a chair = £22
y = cost of a table = £65
Find the total cost of buying twenty chairs and five tables
20x + 5y
Substitute the values of x and y
20x + 5y
= 20(22) + 5(65)
= 440 + 325
= £765
simplify (21a² × 21a⁴) ÷ (21a² × 21a²)
y^2 -1 is a factor of y4 + my3 +2y2 -3y +n
