Fernando wants to know how much interest he will earn on the $4000 he puts into a savings account. He has the interest rate. What other information does he need to know?
Answer:
the time period, and what compounding is usedStep-by-step explanation:
You want to know what else Fernando needs to know to figure how much interest he will earn on $4000, if he has the interest rate.
InterestThere are two interest formulas. One is for simple interest, and one is for compound interest. So, one bit of information Fernando needs is whether interest is being compounded.
The formulas are ...
I = P·r·t . . . . . . . simple interest
I = P((1 +r/n)^(nt) -1) . . . . . . compound interest
If Fernando knows the invested amount P and the interest rate r, then he needs to know 'n' and 't' to be able to choose and use the correct interest formula.

The quadratic function with roots -9 and 7 is f(x) = x² + 2x - 63
What is the quadratic function with zeros -9 and 7?First, recall that a quadratic function has the form:
f(x) = ax² + bx + c
where a, b, and c are constants.
Given the roots of the quadratic function:
-9 and 7
x = -9 and x = 7 are the two distinct solutions to the quadratic equation.
Hence:
x + 9 and x - 7 are the factors of the quadratic equation.
( x + 9 ) ( x - 7 )
Expanding this expression Using FOIL method:
x( x - 7 ) + 9( x - 7 )
x² - 7x + 9x - 63
Collect and add like terms
x² + 2x - 63
Therefore, the function is f(x) = x² + 2x - 63.

Answer:
3y+8x
Step-by-step explanation:
To solve this problem we first have to add similar terms
Adding like terms:
So let us add up the sides that have the same variable. Let us solve for the variable y first ->
[tex]4+y+2y-2\\\\(y+2y)+(4-2)\\\\3y+2[/tex]
Now we have the simplified form of the y. Now let us solve for x ->
[tex]6x+2+2x-4\\\\(6x + 2x) + (2 - 4)\\\\8x - 2[/tex]
Combine both expressions:
To combine these expressions we add the constants and leave the variables. (We do this because different variables cannot be added together)
[tex]8x - 2 +3y +2\\\\8x + 3y + (-2 + 2)\\\\8x+3y+0\\\\8x+3y[/tex]

(10x-23) how do i find x with 106 as an arc
I'm assuming you mean "How do I find the value of x such that the arc length of the circle defined by (10x-23) is 106?" So, there are two possible values of x that would give a circle with arc length 106: x ≈ 2.71 and x ≈ 1.89.
To find the value of x such that the arc length of the circle defined by (10x-23) is 106, we can use the formula for the arc length of a circle:
Arc Length = θr
where θ is the central angle in radians, and r is the radius of the circle.
In this case, we know the arc length is 106, and we need to find the value of x such that the radius is defined by (10x-23). Let's call this radius r.
We can rearrange the formula to solve for the radius:
r = Arc Length / θ
We also know that the central angle in radians is equal to the arc length divided by the radius.
So we can write:
θ = Arc Length / r
Substituting in the values we have:
θ = 106 / (10x-23)
Now we can solve for x. We know that the central angle for a full circle is 2π radians, so the central angle for a circle with radius (10x-23) is:
θ = (2π)(10x-23)
Setting this equal to our previous expression for θ, we have:
106 / (10x-23) = (2π)(10x-23)
Solving for x:
106 = (2π)(10x-23)(10x-23)
106 = (2π)(100x^2 - 460x + 529)
53 = π(100x^2 - 460x + 529)
53/π = 100x^2 - 460x + 529
100x^2 - 460x + (529 - 53/π) = 0
We can solve this quadratic equation using the quadratic formula:
x = [460 ± sqrt(460^2 - 4(100)(529 - 53/π))] / (2(100))
x ≈ 2.71 or x ≈ 1.89
Therefore, there are two possible values of x that would give a circle with arc length 106: x ≈ 2.71 or x ≈ 1.89.

farmer gibson has a heard of 200 cows he sold 60 cows what percentage of his heard remains? Please hurry I need it today!
To find the percentage of Farmer Gibson's herd that remains after he sold 60 cows, we need to calculate the new total number of cows he has.
Number of cows remaining = Total number of cows - Number of cows sold
Number of cows remaining = 200 - 60
Number of cows remaining = 140
So, Farmer Gibson has 140 cows remaining in his herd.
To find the percentage of cows remaining, we can use the following formula:
Percentage = (Number remaining ÷ Total number) x 100
Plugging in the values we have:
Percentage = (140 ÷ 200) x 100
Percentage = 0.7 x 100
Percentage = 70%
Therefore, Farmer Gibson has 70% of his herd remaining after selling 60 cows.

The world record in the long jump is 29 feet 4 inches. How many inches short of 10 yards is the record long jump?
The record long jump is 8 inches short of 10 yards.
We know that 1 yard is equal to 3 feet, so 10 yards is equal to 10 x 3 = 30 feet.
To find out how many inches short of 10 yards the record long jump is, we need to first convert 29 feet 4 inches to inches only.
We can do this by multiplying the number of feet by 12 (since there are 12 inches in a foot) and then adding the number of inches:
29 feet 4 inches = (29 x 12) + 4
= 348 + 4
= 352 inches
Now we can find out how many inches short of 10 yards the record long jump is:
30 feet = 30 x 12 = 360 inches
360 - 352 = 8
Therefore, the record long jump is 8 inches short of 10 yards.

Answer:
26.5
Step-by-step explanation:
The formula for the area of a trapezoid is:
A = (1/2)h(b₁ + b₂)
where h is the height, b₁ and b₂ are the lengths of the parallel bases.
Substituting the given values:
A = (1/2)(4.3 m)(9.2 m + 3.2 m)
A = (1/2)(4.3 m)(12.4 m)
A = 26.52 m²
Rounding to the nearest tenth:
A ≈ 26.5
Therefore, the area of the trapezoid is approximately 26.5 square meters.

Assume the population of circumferences is normally distributed. Determine the minimum sample size
required to construct a 95% confidence interval for the population mean. Assume the population
standard deviation is 0.10 inch..
The minimum sample size required to construct a 95% confidence interval for the population mean is 16.
To determine the minimum sample size required to construct a 95% confidence interval for the population mean circumference of tennis balls within 0.05 inch, we need to use the formula for the margin of error:
Margin of error = Z* (σ/√n)
Where Z* is the z-score corresponding to the desired confidence level, σ is the population standard deviation, and n is the sample size.
Since we want a 95% confidence interval, Z* = 1.96 (from a standard normal distribution table).
We are given that σ = 0.10 inch and we want the margin of error to be 0.05 inch. Plugging in the values, we get:
0.05 = 1.96 * (0.10 / √n)
Solving for n, we get:
n = [(1.96 * 0.10) / 0.05]² = 15.36
We can't have a fractional sample size, so we round up to the nearest whole number. Therefore, the minimum sample size required is 16.
This means that the manufacturer needs to randomly select and measure the circumferences of at least 16 tennis balls to estimate the population mean circumference with 95% confidence and a margin of error of 0.05 inch.

The z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is obtained by the equation presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution of the data-set, depending if the obtained z-score is positive(above the mean) or negative(below the mean).The z-score table is used to obtain the p-value of the z-score, and it represents the percentile of the measure X in the distribution.The mean and the standard deviation for this problem are given as follows:
[tex]\mu = 515, \sigma = 125[/tex]
The proportion of scores less than 675 is the p-value of Z when X = 675, hence:
Z = (675 - 515)/125
Z = 1.28
Z = 1.28 has a p-value of 0.8997.
Hence the percentage is 89.97%.
The proportion of scores greater than 550 is one subtracted by the p-value of Z when X = 550, hence:
Z = (550 - 515)/125
Z = 0.28
Z = 0.28 has a p-value of 0.6103.
1 - 0.6103 = 0.3897, hence the amount is given as follows:
