Answer:
The starting balance of the 3rd year is $811.20.
The ending balance for the 3rd year is $843.65.
The interest earned in the 4th year is $33.75.
Step-by-step explanation:
750 × (1 + 4%)^n
750 × (1.04)^n
750 × 1.04² = 811.2
(End of second year, starting of third year)
750 × 1.04³ = 843.648
In third year: 843.648 - 811.2
= 32.448
750 × 1.04⁴ = 877.39392
During the fourth year:
877.39392 - 843.648
33.74592
Answer:
The starting balance of the 3rd year is $811.20.
The ending balance for the 3rd year is $843.65.

What is the value of log27 9
Write the equation in vertex form for the graph below.
Given:
The graph of the parabola with vertex (-2,-4)
We need to determine the equation of the parabola in vertex form.
Equation in vertex form:
The general form of the equation of the parabola in vertex form is given by
[tex]y=a(x-h)^2+k[/tex]
where a is the constant and (h,k) is the vertex.
Substituting the vertex (-2,-4) in the above formula, we get;
[tex]y=a(x+2)^2-4[/tex] -------- (1)
To determine the value of a, let us substitute the point that the parabola passes through.
Hence, substituting the point (0,8) in equation (1), we get;
[tex]8=a(0+2)^2-4[/tex]
[tex]8=a(2)^2-4[/tex]
[tex]8=4a-4[/tex]
[tex]12=4a[/tex]
[tex]3=a[/tex]
Thus, the value of a is 3.
Substituting the value a = 3 in equation (1), we get;
[tex]y=3(x+2)^2-4[/tex]
Thus, the equation of the parabola in vertex form is [tex]y=3(x+2)^2-4[/tex]

What is a right-angled triangle?A right-angled triangle is a geometric shape that has one internal angle measuring exactly 90 degrees. This angle, known as the right angle, is formed by the intersection of two sides of the triangle.
The other two angles in the triangle are acute angles, which means they measure less than 90 degrees. The side opposite the right angle is called the hypotenuse, and it is the longest side in the triangle.
The other two sides are called the legs, and they form the right angle. The lengths of the legs and the hypotenuse of a right-angled triangle are related by the Pythagorean theorem, which states that the square of the hypotenuse is equal to the sum of the squares of the legs.

Elian won a sweepstakes and will receive money every week for 52 weeks. The first week, he will receive $500. Every week after that, he will receive $50 more than he received the previous week.
The amounts of money Elian receives each week form an arithmetic sequence. What is the explicit formula for the sequence?
The answer needs to be in simplified form.
Here is the explicit formula for the arithmetic sequence: an = 500 + 50(n - 1)
What does the explicit formula mean?where:
an is the amount of money Elian receives in week n
500 is the first payment
50 is the common difference
n is the week number (1-indexed)
For example, in week 2, Elian will receive $550 because 500+50(2−1)=550.

The probability that a child will learn to swim before age 6 is 0.312. If you take a group of 12 children, what is the probability that 1 or fewer of the children will learn to swim before age 6? (Round your answer to 3 decimal places if necessary.)
Answer:
The probability of 1 or less children from that group to learn how to swim before 6 years of age is 0.072
Step-by-step explanation:
In this case we need to compute the probability of none of these 12 children learns to swim before 6 years of age. This is given by:
p(0) = (1 - 0.312)^(12) = 0.688^(12) = 0.01124
We now need to calculate the probability that one child learns to swim before 6 years of age.
p(1) = 12*0.312*(1 - 0.312)^(11) = 3.744*(0.688)^(11)
p(1) = 3.744*0.01634
p(1) = 0.0612
The probability of 1 or less children from that group to learn how to swim before 6 years of age is:
p = p(0) + p(1) = 0.01124 + 0.0612 = 0.07244
The probability that 1 or fewer of the 12 children will learn to swim before age 6 is approximately 0.072 when rounded to three decimal places.
1. Given:
- Probability that a child will learn to swim before age 6, ( p = 0.312 )
- Number of children, ( n = 12 )
2. Calculating ( P(X = 0) ):
[tex]\[P(X = 0) = \binom{12}{0} (0.312)^0 (1 - 0.312)^{12}\]\[P(X = 0) = 1 \times 1 \times (0.688)^{12}\]\[P(X = 0) \approx (0.688)^{12}\][/tex]
Using a calculator for [tex]\((0.688)^{12}\)[/tex]:
[tex]\[(0.688)^{12} \approx 0.0088\][/tex]
3. Calculating ( P(X = 1) ):
[tex]\[P(X = 1) = \binom{12}{1} (0.312)^1 (1 - 0.312)^{11}\]\[P(X = 1) = 12 \times 0.312 \times (0.688)^{11}\][/tex]
Using the binomial cumulative distribution function (CDF):
[tex]\[P(X \leq 1) = \sum_{k=0}^{1} \binom{12}{k} (0.312)^k (0.688)^{12-k}\][/tex]
Using the binomial probability tables or calculator, we get:
[tex]\[P(X = 0) \approx 0.0088\]\[P(X = 1) \approx 0.0623\][/tex]
Summing these:
[tex]\[P(X \leq 1) \approx 0.0088 + 0.0623 = 0.0711\][/tex]
Thus, the probability that 1 or fewer of the 12 children will learn to swim before age 6 is approximately 0.0711, which rounds to 0.072.
rip van winkle sell asleep for a very long time when he fell asleep, his beard was 8 millimeters long and each passing week and grew 2 additional millimeters
graph the relationship between the length of rip van winkle‘s beard (in millimeters) and time (in seconds)
please answer asap
Answer:
Time in weeks you mean not seconds.
His beard should be graphed at point xy 1, 8 and continue at a gradient rate 8 rise / 1 rise showing m = 8/1 . to show one week to be able to meet up with .
Step-by-step explanation:
There are 604800 seconds in a week so first multiply by 5.5 weeks to find the first green dot. 604800 x 5.5 = 3326400 so we know the .5 option shows a rounded next week number.
We can either work downwards to zero or start at 1,8 ever way they will be even balance as 8/32 = 4 8/36 = 4.4 growth and this for example would show a rounded amount, so that 8/8 would be 8 and show the first week, or can be skipped out and start with y = 2x + 10 and then when referring to show .5 growth it would still be a whole number within the equation representing 12 and still be a whole number representing 2 weeks.
The graph does not speak of seconds but weeks, but if you want to use the above and try for 604800 seconds as shown for 1 week, you will have a tough time graphing. Stick to 2,4,6 8, 10, 12, 14, 16, 18 weeks multiplied by 12 = y = 1 + 8 = 0
y = 2x +8 +2 = 1
y = 3x + 8 +2 = 2

How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
Ax+By=C is the usual form for two-variable linear equations. A standard form linear equation is, for instance, 2x+3y=5.
In other words, an equation is a set of variables that are constrained through a situation or case.
To form an equation we must know the constraint of that condition,
For example x < 5 is a constraint.
Another example of a constraint is;
7x + 3y = 8 like that
Let say
Your age is = x
21 year ago your age were = x - 21
Now it was half the age x so,
x - 21 = (1/2)x
2x - 42 = x
x = 42
So your current age will be 42 years old.

Equation is y=kx. We have four chance to figure out k; hopefully they all give the same result
x=9, y=63, y=kx becomes 63=k(9) so k=63/9=7
x=4, y=28, 28=k(4), k=7
The constant of proportionality is 7; we check 2×7=14, 11×7=77
Answer: k=7, y=7x
Answer:
y=kx
y=k(7)x
y=7x(11)
y=7*11
y=77

The Kendall family was preparing to go hiking with the Smith family. In preparation,
the Kendall's bought 8 Cliff Bars and 4 appleslfor $12.40. The Smith family spent
$24.30 on 15 Cliff Bars and 9 apples. What is the difference in price between a cliff
bar and an apple?
Answer:$9.3 is the bars and the rest is the apples
Step-by-step explanation:because you take away from the bars than what is left is the apples.
The difference in price between a cliff bar and an apple is $0.50.
To determine the difference in price between a cliff bar and an apple, we must create two equations based on the information provided:
8C + 4A = 12.40 (equation 1 for the Kendall family)
15C + 9A = 24.30 (equation 2 for the Smith family)
We can solve these equations using substitution or elimination. Let's use the elimination method:
Multiply equation 1 by 2 to get 16C + 8A = 24.80 (equation 3).
Subtract equation 3 from equation 2: (15C + 9A) - (16C + 8A) = 24.30 - 24.80 which gives us -C + A = -0.50.
From this simplified equation, we gather that the price difference between a cliff bar and an apple is $0.50.
Therefore, the difference in price between a cliff bar and an apple is $0.50.

A can of orange juice has a circular base with an area of 156 square centimeters. The height of the can is 20 centimeters.
What is the volume of the can of orange juice in cubic centimeters?
A. 3120
B. 62,400
C. 176
D. 8000
Final answer:
To calculate the volume of the orange juice can, the formula V = πr²h is used. By finding the radius from the given area of the base and then using the height of the can, the volume is calculated as 3120 cm³, which corresponds to answer choice A.
Explanation:
The student has asked a question about calculating the volume of a cylindrical can of orange juice. Given the area of the circular base is 156 square centimeters and the height of the can is 20 centimeters, the volume can be found by using the formula V = πr²h, where V stands for volume, r is the radius of the base, and h is the height of the cylinder. First, we need to find the radius (r) of the base from the given area, and then substitute it into the volume formula along with the height (h).
To find the radius, we use the formula for the area of a circle, A = πr², where A = 156 cm². Solving for r, we have r = √(A/π). Plugging the area into this formula, the radius (r) is:
r = √(156/π) cm
Then we substitute the radius and height into the volume formula:
V = πr²h
V = π(√(156/π))^2 × 20 cm
V = 156 × 20 cm³
V = 3120 cm³
Therefore, the correct answer is A. 3120 cubic centimeters.
