Answer:
Step-by-step explanation:
Krystal was given $3000 when she turned 2 years old. Her parents invested at a 2% interest rate compounded annually. No deposits or withdrawals were made. Determine how much money Krystal had in the account when she turned 18.
Answer:
4131.38
Step-by-step explanation:
Since it's compounded annually, and no time needs to be converted, we can use the formula [tex]y=Pe^r^t[/tex], where P is the starting amount, e is Euler's number, r is the rate in decimals, and t is time. The first task would be to find the t. The question set us a timeframe of 2 to 18, so 18-2=16, therefore our t is 16. Plugin the known into the formula and calculate:
[tex]y=3000e^0^.^0^2^*^1^6\\y=3000*e^0^.^3^2\\y=4131.38[/tex]

Solve for 'x' in both of the following problems.
Answer:
x = 73° , x = 7
Step-by-step explanation:
(1)
the measure of an inscribed angle is half the measure of its intercepted arc.
∠ B = [tex]\frac{1}{2}[/tex] AC = [tex]\frac{1}{2}[/tex] × 128° = 64°
the sum of the 3 angles in Δ ABC = 180°
then
x = 180° - (64 + 43)° = 180° - 107° = 73°
(2)
2 chords iintersecting in a circle, then
the products of the parts of one chord is equal to the product of the parts of the other chord, that is
KH × HI = JH × HG ( substitute values )
10x = 14 × 5 = 70 ( divide both sides by 10 )
x = 7
Each interior angle of a regular polygon has a measure of 40.how many sides does the polygon have?
Given Information :-
⠀
Each exterior angle of a regular polygon has a measure of 40°⠀
To Find :-
⠀
The number of sides of the polygon⠀
Formula Used :-
⠀
[tex] \qquad \star \: \underline{ \boxed{ \green{ \sf No.~of~sides = \dfrac{360^ \circ}{exterior ~angle}}}} \: \star[/tex]
⠀
Solution :-
⠀
Using the formula,
⠀
[tex] \sf \dashrightarrow No. ~of~sides= \dfrac{360}{40} \\ \\ \\ \sf \dashrightarrow No. ~of~sides= \frac{ \cancel{360}}{ \cancel{40} } \\ \\ \\ \sf \dashrightarrow No. ~of~sides= \underline{ \boxed{ \blue { \frak{9}}}} \: \star[/tex]
⠀
Thus, the polygon is a nonagon, and hence has 9 sides.

Multiply: (3x+7)(5x^2-3x+6)
Answer:
15x^3+26x^2-3x+42
Step-by-step explanation:
(3x+7)(5x^2-3x+6)
15x^3-9x^2+18x+35x^2-21x+42
15x^3-9x^2+35x^2+18x-21x+42
15x^3+26x^2-3x+42
Answer:
15x³ + 26x² - 3x + 42
Step-by-step explanation:
Hi there!
We are given the polynomials 3x+7 and 5x²-3x+6
We want to multiply them together
(3x+7)(5x²-3x+6)
To that, we need to distribute each term of the binomials to each other, and then add them together.
What this means is that we need to multiply 3x by 5x², -3x, and 6, then add them together. Then, multiply 7 by 5x², -3x, and 6. Add those together, and then add everything together.
So, let's first start by multiplying 3x by everything:
3x * 5x² = 15x³
3x * -3x = -9x²
3x * 6 = 18x
Add them together: 15x³ + -9x² + 18x
Now with 7:
7 * 5x² = 35x²
7 * -3x = -21x
7 * 6 = 42
Add them together: 35x² + -21x + 42
Now add 15x³ + -9x² + 18x and 35x² + -21x + 42 together:
15x³ + -9x² + 18x + 35x² + -21x + 42
Combine like terms:
15x³ + 26x² - 3x + 42
Hope this helps!

The area of a circle is 9π m². What is the circumference, in meters? Express answer in terms of π
Answer:
20.25 pi
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
9 pi = 2 * pi *r
Divide each side by 2pi
9pi / 2 pi = 2 pi r / 2 pi
4.5 = r
Now we can find area
A = pi r^2
= pi ( 4.5)^2
20.25 pi

Step-by-step explanation:
volume of 1 can = πr²h = 22/7 × 5/2 × 5/2 × 8
= 157.14 cm³
volume of juice in 6 cans = 6 × 157.14 = 942.84cm³

Using the z-distribution, it is found that the margin of error for a 95% confidence interval is of $0.04.
What is a z-distribution confidence interval?The confidence interval is:

A car rental agency rent compact, midsize, and luxury cars. Its goal is to purchase 48 cars for a total of $932,000 and to earn a daily rental of $ 1,265 from all the cars. The compact cars cost $13,000 each earn $ 20 per day in rental, the midsize cars cost $ 25,000 each earn $ 27 per day, and the luxury cars cost $ 29,000 each and earn $ 45 per day. Your task will be to find the number of each type of car the agency should purchase to meet its goal.
Answer:
25 compact15 midsize8 luxuryStep-by-step explanation:
The set of relationships can be formulated as three equations in three unknowns. These can be written as an augmented matrix and solved using a calculator.
Let x, y, z represent the numbers of compact, midsize, and luxury cars, respectively. Then the relations are ...
x + y + z = 48 . . . . . . total number of cars purchased
13x +25y +39z = 932 . . . . . total cost in thousands
20x +27y +45z = 1265 . . . . daily rental revenue
The augmented matrix of coefficients looks like ...
[tex]\left[\begin{array}{ccc|c}1&1&1&48\\13&25&39&932\\20&27&45&1265\end{array}\right][/tex]
And its solution is ...
(x, y, z) = (25, 15, 8)
The agency should purchase 25 compacts, 15 midsize, and 8 luxury cars.

Find the solutions to the equation below.
Check all the apply.
16x^2 - 64 = 0
A. x = 4
B. x = 2
C. x = -64
D. x = -2
E. x = -4
F. x = -8
Answer:
x = 2
x = - 2
Step-by-step explanation:
⇒ 1: Common Factor
16x² - 64 = 016(x² - 4) = 0⇒ 2: Use the sum-product pattern
16 (x² - 4) = 016 (x² + 2x - 2x - 4) = 0⇒ 3: Common factor from the two pairs
16((x² + 2x) + (-2x - 4) = 016(x(x+2)-2(x+2))=0I dont feel like adding more details.
- rewrite in factored form
16(x(x+2)-2(x+2))=0
16(x-2)(x+2)=0
- create seperate equations
16(x-2)(x+2)=0
x-2=0
x+2=0
- solve
*rearrange and isolate the variable to find each solution
x = -2
x = 2
Answer:
B.x=2
Step-by-step explanation:
[tex]16x ^{2} - 64 = 0[/tex]
[tex]16x ^{2} = 64[/tex]
[tex]4 ^{2} {x}^{2} = {4}^{3} [/tex]
