What future value means?

The method that results in more money after 2 years is Peggy's investment.

Which method results in more money in 2 years?

The formula for calculating the future value of an investment:

FV = P (1 + r)^nm

FV = Future value

P = Present value

R = interest rate

m = number of compounding

N = number of years

Future value of Larry's investment: $350 x [1 + (0.04/4)]^(4 x 2) = $379

Future value of Peggy's investment: $350 x [1 + (0.06/12)]^(12 x 2) = $394.51

The upper and lower bounds of each of the numbers are;

1a) Upper bound of 6 = 6.5

Lower bound of 6 = 5.5

b) Upper bound of 83 = 83.5

Lower bound of 83 = 82.5

c) Upper bound of 152 = 152.5

The range as intervals of inequality are;

i) 5.5 ≤ x ≤ 6.5

ii) 82.5 ≤ x ≤ 83.5

iii) 151.5 ≤ x ≤ 152.5

The procedure to identify the upper and lower bounds is;

1) Identify the place value of the degree of accuracy stated.

2) Divide this place value by 2.

3) Add this amount to the given value to find the upper bound, subtract this amount from the given value to find the lower bound.

ai) Since it was approximated to the nearest whole number, then we say that the place value of the degree of accuracy is 1.

Divide by 2 to get; 1/2 = 0.5

Upper bound of 6 = 6 + 0.5 = 6.5

Lower bound of 6 = 6 - 0.5 = 5.5

ii) Since it was approximated to the nearest whole number, then we say that the place value of the degree of accuracy is 1.

Divide by 2 to get; 1/2 = 0.5

Upper bound of 83 = 83 + 0.5 = 83.5

Lower bound of 83 = 83 - 0.5 = 82.5

iii) Since it was approximated to the nearest whole number, then we say that the place value of the degree of accuracy is 1.

Divide by 2 to get; 1/2 = 0.5

Upper bound of 152 = 152 + 0.5 = 152.5

Lower bound of 152 = 152 - 0.5 = 151.5

bi) The range as an inequality is;

5.5 ≤ x ≤ 6.5

ii) The range as an inequality is;

82.5 ≤ x ≤ 83.5

Equation of the new perpendicular line is  [tex]y - y_{1} = -\frac{1}{4} (x- x_1)[/tex]

How to calculate the new perpendicular line?

The given equation is:

y- 8=4 (x-5)​

This equation is of the point- slope form

[tex]y- y_{1}= m(x-x_{1})[/tex]

y - 8 = 4( x-5 )​

So, the slope (m) is m = 4

The points [tex](x_1,y_1) = (5,8)[/tex]

Hence, slope of the line perpendicular to the given line is

m = [tex]-\frac{1}{4}[/tex]

The equation of the new perpendicular line is :

[tex]y- y_{1}= m(x-x_{1})\\\\y - y_{1} = -\frac{1}{4} (x- x_1)[/tex]

The solution to the inequality expression is 5/13 ≤ x  < 2

The inequality expression is given as

-24x is less than or equal to 2x -10 is less than -6

Rewrite the expression properly as follows

-24x ≤ 2x - 10 < -6

Expand the expression

So, we have the following expression

-24x ≤ 2x - 10 and 2x - 10  < -6

Evaluate the like terms in the above statements

So, we have

-26x ≤ - 10 and 2x   < 4

Divide the constants by the coefficient of x

So, we have

x ≥ 5/13 and x  < 2

Rewrite as

5/13 ≤ x and x  < 2

Combine the inequalities

The equation of parabola is y = -8(x -3)² - 9.

A parabola is an approximately U-shaped, mirror-symmetrical plane curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. A parabola can be described using a point and a line.

Given Data

Focus = (3, -9)

Directrix: y = -5

The focus-passing line has an equation of x = -5 that is perpendicular to the directrix. The symmetry line of a parabola is seen here.

The parameter of the parabola is the separation between the focus and the directrix, so

p = -9 - 3

p = -12

p = 12

The distance between the focus and the directrix is divided into two equal portions by the parabola's vertex, which is located on the line of symmetry. Its coordinates are as follows: (3,-9).

Since a parabola moves in the opposite direction of y, its equation is

y -(-9) = -2(4(x -3)²)

y + 9 = -8(x-3)²

y = -8(x -3)² - 9

The equation of parabola is y = -8(x -3)² - 9.

Answer:  45

Step-by-step explanation:

Answer:

for calculator steps

Step-by-step explanation:

-Find out what 1% of the whole amount (B) is - to do this you divide it by 100.

-Once you know the value of 1% you can multiply this amount by the number of percent you want to find.

-If you want to find 10% of 50 you divide 50 by 100.

-From this you know that 1% of 50 is 0.5

-So to find 10% you just multiply 0.5 by 10

-0.5 x 10 = 5

-10% of 50 = 5

Factor the trinomial to find a possible combination of dimentions that the rectangle could have:

To factor the trinomial, remember that the following product of binomials is equal to:

Then, we need to find two numbers a and b such that their product is equal to the constant term -18 and their sum is equal to the linear coefficient -3.

Since the product is negative, one number is negative and the other is positive.

Since the sum is negative, the greatest number is negative.

Two numbers whose difference is 3 and whose product is 18 are 6 and 3.

Notice that:

Then:

Therefore, the dimensions of the rectangle, are:

The equation of a line is y=mx+b

m is the slope

b is the y intercept

Looking at the graph, the y intercept is 10 because the line crosses the y-axis at 10

Since they said the slope is 10, the equation of the line is:

y=10x+10

The surface area is increasing at the rate of (60 x + 150) cm² per second.

Let the side of the cube be x cm.

s = x cm

Surface area of the cube will be:

S = 6 x² cm²

Now, we are given that, the side of the cube is expanding 5 cm per second.

So, the side of the cube after 1 second will be:

s' = x + 5 cm

Surface area will be:

S' = 6 (x + 5)² cm²

S' = (6x² + 150 + 60 x) cm²

Change in the surface area is:

ΔS = (6x² + 150 + 60 x) cm² - 6 x² cm²

ΔS = (60 x + 150) cm²

Therefore, the surface area is increasing at the rate of (60 x + 150) cm² per second.

Answer:

Step-by-step explanation:

The new variance for the data is 0.35 .

In statistics and probability theory, variance is the predicted squared deviation of a stochastic process from its mean or actual values.

Dispersion, or how far apart from the mean a set of data are from one another, is measured by variance.

A few ideas that involve variance are descriptive statistics, parameter estimation, testing hypotheses, quality of fit, and Monte Carlo sampling.

Variance is a vital tool in the fields where statistical data analysis is widely used.

The standard deviation squared is a measure of the variance, which is also referred to as the second systematic of a distribution and the correlation between the random variable and itself.

We know that variance = (standard deviation)²

When the value of the data increases by 25 cents a box , then the standard deviation will remain the same as the mean will only increase and the change in mean has no effect on the SD.

Hence the variance will effectively remain the same.

therefore the new variance is 0.35

14 and 22 are not equal, Thus it does not form a proportion.

The square has sides of 12 in and the area of a square is side × side. The area of the shaded region exists 144 sq. in.

The area of a square can be estimated by squaring the number describing the measure of the side of the square.

The area of a shape exists as the number of unit squares needed to completely cover it. Therefore, it exists calculated and expressed in square units.

The area of a square exists equivalent to (side) × (side) square units. The area of a square when the diagonal, d, exists given exists d²÷2 square units.
