Pierre deposits $9,000 in a certificate of deposit that pays 1.4% interest, compounded semi-annually
How much interest does the account earn in the first six months?
What is the balance after six months?
Answer:
Interest = $63
Balance = $2,063
Step-by-step explanation:
Compound Interest Formula
[tex]\boxed{\sf I=P\left(1+\frac{r}{n}\right)^{nt} -P}[/tex]
where:
I = Total interest.P = Principal amount.r = Interest rate (in decimal form).n = Number of times interest is applied per year.t = Number of time periods (years) elapsed.Given:
P = $9,000r = 1.4% = 0.014n = 2 (semi-annually)t = 0.5 (half a year)Substitute the given values into the formula and solve for I:
[tex]\implies \sf I=9000\left(1+\dfrac{0.014}{2}\right)^{2 \times 0.5}-9000[/tex]
[tex]\implies \sf I=9000\left(1+0.007\right)^{1}-9000[/tex]
[tex]\implies \sf I=9000\left(1.007\right)-9000[/tex]
[tex]\implies \sf I=9063-9000[/tex]
[tex]\implies \sf I=63[/tex]
Therefore, the account earns $63 interest in the first six months.
The balance after six months is $2,063.

Form a polynomial whose zeros and degree are given Zeros: -2, multiplicity 1; 3, multiplicity 2; degrees 3
The polynomial of 3rd degree whose zeros and degree are given as for zero of (-2), multiplicity 1 and for zero of (3), multiplicity 2 is [tex]f(x)=(x^{3}-10x^{2} -15x+18)[/tex]
As per the question statement, a 3rd degree polynomial has a zero of (-2), multiplicity 1 and another zero of (3), multiplicity 2.
We are required to determine the polynomial.
Since, (-2) is a zero of the polynomial, then [tex][x-(-2)]=(x+2)[/tex] will be a factor of the polynomial. And since for zero of (-2), multiplicity is 1, this means that the factor of (x + 2) is only multiplied once.
Similarly, as (3) is another zero of the polynomial, then [tex](x-3)[/tex] will be a factor of the polynomial. And since for zero of (3), multiplicity is 2, this means that the factor of (x - 3) will be multiplied twice, i.e., [tex](x-3)^{2}[/tex].
Therefore, our function, say, f(x) will be [tex](x+2)(x-3)^2[/tex]
[tex]or, f(x) = (x+2)(x-3)^2\\or, f(x) = (x + 2)(x^{2} +9-12x)\\or,f(x) =x^{3}+9x-12x^{2} +2x^{2} +18-24x\\ or, f(x)=x^{3}+(2x^{2}-12x^{2})+(9x-24x)+18\\or, f(x)=(x^{3}-10x^{2} -15x+18)[/tex]
Hence, our required polynomial is [tex]f(x)=(x^{3}-10x^{2} -15x+18)[/tex]

The cost of 12 oranges and 7 apples is $5.36. 8 oranges and 5 apples cost is $3.68. Find the cost of each.
Answer:
oranges €0·2б apples€0·32
Step-by-step explanation:
Answer:
apple $0.32 , orange $0.26
Step-by-step explanation:
let o and a represent the cost of an orange and apple, respectively , then
12o + 7a = 5.36 → (1)
8o + 5a = 3.68 → (2)
multiplying (1) by 8 and (2) by - 12 and adding will eliminate o
96o + 56a = 42.88 → (3)
- 96o - 60a = - 44.16 → (4)
add (3) and (4) term by term to eliminate o
0 - 4a = - 1.28
- 4a = - 1.28 ( divide both sides by - 4 )
a = 0.32
substitute a = 0.32 into either of the 2 equations and solve for o
substituting into (1)
12o + 7(0.32) = 5.36
12o + 2.24 = 5.36 ( subtract 2.24 from both sides )
12o = 3.12 ( divide both sides by 12 )
o = 0.26
the cost of an apple is $0.32 and the cost of an orange is $0.26
Give the rate in miles per hour round to the nearest tenth Rachel jogs 20 feet in three seconds
According to the formula speed = distance / time The rate in miles per hour is 4.54
If you know how far something has traveled and how long it took to get there, you can calculate its average speed. Speed is calculated as follows: speed = distance * time. Knowing the units for distance and time is necessary to calculate the units for speed.
Rachel jogs 20 feet in 3 seconds
then by the formula
speed = distance/time
speed = 20 feet / 3 seconds
speed = 6.666667 feet per hour
but this speed is in feet per seconds to convert the speed from feet per seconds to miles per hour we need to multiply by 0.681818,
speed = 6.66667*0.681818
speed = 4.5454 miles per hour

Answer:
angle 1 = 51
angle 2 = 39
Step-by-step explanation:
The sum of two angles is equal to 90° since they are complementary angles
angle 1 + angle 2 = 90° rewrite equation using given values
x + 38 + 3x = 90 add like terms
4x + 38 = 90 subtract 38 from both sides
4x = 52 divide both sides by 4
x = 13 now to find the measure of each angle replace x with 13
angle 1 = 51

The value of the variable x in the expression is 9.
How to solve for a variable in an expression?The mathematical expression is as follows:
(x+12) + (4x-16) = 6x-13
Therefore, let's open the brackets
(x+12) + (4x-16) = 6x - 13
x + 12 + 4x - 16 = 6x - 13
Combine the like terms
x + 12 + 4x - 16 = 6x - 13
x + 4x + 12 - 16 = 6x - 13
Do the arithmetic of the like terms on both sides
x + 4x + 12 - 16 = 6x - 13
5x - 4 = 6x - 13
Add 4 to both sides
5x - 4 = 6x - 13
5x - 4 + 4 = 6x - 13 + 4
5x = 6x - 9
subtract 6x from both sides
5x = 6x - 9
5x - 6x = 6x - 6x - 9
-x = -9
divide both sides by -1
Therefore,
x = 9
The value of the variable x in the expression is 9.
