Answer:

$51,282

Step-by-step explanation:

100*1.75%=1.75*504 months (42 years)=882

100*504 months (42 years)=50,400

50,400+882=$51,282

Hope this is correct, and helps you out :)

He will have $74,356.50 in his account.

Interest is the price you pay to borrow money or the cost you charge to lend money.

Initial investment (PV)= $100

Number of periods (n)=42 years

Interest rate (i)= 1.75%

So, FV= P(1+r/100)^(nt) -1)) / (r/n)

FV= 100(1+0.0175/100)^(12*42) -1)) / (0.0175/12)

FV= $74,356.50

Step-by-step explanation:

An odd function is a function f such that, for all x in the domain of f, -f(x) = f(-x). A one-to-one function is a function f such that f(a) = f(b) implies a = b.

The required value of a number of people is 20 who don't do either.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

here, we have,

Column 1 has the entries run, do not run, and total. Column 2 is called lift weights, and it has the values 40, blank, and 65. Column 3 is captioned "do not lift weights" and has entries blank, x, and blank. Column 4 is called total and has the entries 75, blank, and 120.

As per the given information, the required solution would be as:

The number of people who do not run or lift weights by first determining that 55 individuals do not lift weights and 35 people run but do not lift weights. When you subtract 35 from 55, you get 20 people who don't do either.

Thus, the required value of a number of people is 20 who don't do either.

The number x represents the number of people who do not run and do not lift weights. To calculate x, subtract the number of people who lift weights from the total number, then subtract the number of people who run and lift weights.

To find the number that x represents, we can use the information given in a table with a row and column structure. From the total number of people (120) and the number of people that lift weights (65), we deduct the number that run and lift weights (40), leaving us with the number of people who either do not run or do not lift weights.

The total number of people that run is given as 75. Therefore, the number who do not run is 120 - 75 = 45. We know that 65 people lift weights, so by subtraction, 120 - 65 gives us the total number of people who do not lift weights.

Now, using the total number of people who do not lift weights, we can calculate the value of x, which represents the number of people who do not run and also do not lift weights. Subtracting the number of people who run but do not lift weights from the total number who do not lift weights gives us:

Number of people who do not lift weights = Total number of people - Number of people who lift weights

Number of people who do not lift weights = 120 - 65 = 55

Therefore, x equals 55 - 40, since 40 is the number of people who run and lift weights.

x = 55 - 40 = 15

The answer to your question is 42°

Step-by-step explanation:

Data

m∠BOC = 6x - 6

m∠AOB = 5x + 8

m∠BOC = ?

Process

We know that the segments OA ⊥ OC so they are complementary angles.

1.- The sum of complementary angles equals 90°

                 m∠BOC + m∠AOB = 90°

2.- Substitution

                6x - 6 + 5x + 8 = 90°

3.- Solve for x

                6x + 5x = 90 + 6 - 8

4.- Simplify

                       11x = 88

5.- Result

                          x = 88/11

                          x = 8

6.- Calculate m∠BOC

             m∠BOC = 6(8) - 6

                            = 48 - 6

                            = 42°

Answer:

y = x² + 2x + 1

Step-by-step explanation:

Same y value at x = -2 & x = 0

So line of symmetry is at:

x = (-2+0)/2

x = -1

Vertex: (-1,0)

y = a(x - -1)² + 0

y = a(x + 1)²

At x = 1, y = 4

4 = a(1 + 1)²

4 = 4a

a = 1

y = (x + 1)²

y = x² + 2x + 1

The general form of the equation of the quadratic function is x² + 2x + 1

The formula expressing the equation of the quadratic function will be expressed as:

y = a(x -h)² + k

From the table shown, we can see that the y-values are the same at where x = -2 and 0

Get the line of symmetry:

[tex]x =\frac{-2+0}{2}\\x=\frac{-2}{2} \\x=-1[/tex]

We can see that when x = -1, y = 0. Hence the vertex will be at (-1, 0)

h = -1

k = 0

Substitute into the formula y = a(x -h)² + k

y = a(x -(-1))² + 0

y = a(x+1)²

From the table at where x = 1, y = 4. On substituting to get "a" we have:

4 = a(1+1)²

4 = 4a

a = 1

Get the required quadratic function by substituting the parameters into the general formula as shown:

y = a(x -h)² + k

y = 1(x +1)² + 0

y = (x+1)²

y = (x+1) (x+1)

y = x² + x +x + 1

y = x² + 2x + 1

Hence the general form of the equation of the quadratic function is x² + 2x + 1

Answer:

s ≥ 170

Step-by-step explanation:

The problem raises the following statement: "The cruising speed of the bullet train will be at least 170 miles per hour"

Which means that the train has a speed of 170 miles for now or higher, knowing this we can pose the inequality.

Knowing that "s" is the train's cruising speed (in miles per hour), we have to:

s ≥ 170

This would be the inequality that the statement represents.

The inequality representing the bullet train's cruising speed being at least 170 miles per hour is s ≥ 170.

The situation described involves finding an inequality for the train's cruising speed. To represent the train's cruising speed in miles per hour, we use the variable s.

Given that the cruising speed of the bullet train will be at least 170 miles per hour, we need an inequality that expresses this condition.

The inequality is:

s ≥ 170

This means that the cruising speed s can be 170 miles per hour or higher.

Answer: 1256cm

Step-by-step explanation:

Final answer:

When Josie doubles the radius of the bird bath to build a larger one, the new surface area will be 1256 cm², as surface area quadruples when doubling the radius of a circle.

Explanation:

Josie calculated that the surface area of her small bird bath with a radius of 10 cm is 314 cm^2. If she doubles the dimensions for a larger bird bath, the new radius will be 20 cm. To find the surface area of the larger bird bath, we use the formula for the area of a circle, A = πr².

Plugging in the new radius:

A = 3.14 × (20 cm)^2

A = 3.14 × 400 cm^2

A = 1256 cm2

This means the surface area for the larger bird bath Josie plans to build will have 1256 cm^2 for bird bathing. This calculation demonstrates how the surface area of a circle quadruples when the radius is doubled, which is consistent with the principle that surface area scales with the square of the dimension changes.
