To calculate the amount of money that needs to be set aside today to purchase a new piece of equipment in 3 years, we need to find the future value of the equipment and calculate the present value of that future amount.

First, let's find the future value of the equipment:

The cost of the equipment is expected to increase by 3% per year, so after 3 years the cost will be:

$75,000 * (1 + 0.03)^3 = $78,225

Next, let's find the present value of that future amount:

The money is expected to earn 9% interest compounded annually, so to find the present value, we need to discount the future amount by the interest rate. We can use the formula:

PV = FV / (1 + r)^t

where PV is the present value, FV is the future value, r is the interest rate, and t is the number of years.

Plugging in the values, we get:

PV = $78,225 / (1 + 0.09)^3 = $73,232.57

So, to purchase the equipment in 3 years, we need to set aside $73,232.57 today.

Answer:

4x² + 4x + 9 = 0 , has no real solutions

Step-by-step explanation:

given a quadratic equation in standard form

ax² + bx + c = 0 ( a ≠ 0 )

then the nature of the solutions can be determined using the discriminant.

Δ = b² - 4ac

• if b² - 4ac > 0 , then real solutions

• if b² - 4ac = 0 , then real and equal solutions

• if b² - 4ac < 0 , then no real solutions

4x² + 4x + 9 = 0 ← in standard form

with a = 4, b = 4 , c = 9

b² - 4ac

= 4² - (4 × 4 × 9)

= 16 - 144

= - 128 ← no real solutions

------------------------------------------

- 4x² + 56x - 196 = 0 ← in standard form

with a = - 4 , b = 56 , c = - 196

b² - 4ac

= 56² - (4 × - 4 × - 196)

= 3136 - 3136

= 0 ← has real solutions

-------------------------------------------

- 5x² - 10x + 10 = 0 ← in standard form

with a = - 5 , b = - 10 , c = 10

b² - 4ac

= (- 10)² - (4 × - 5 × 10)

= 100 - (- 200)

= 100 + 200

= 300 ← has real solutions

Based on the given trapeziums, each problem's answers are:

Let's discuss each problem we have:

1. The given trapezium is an isosceles trapezium, hence:

J = K = 7x  + 2

M = L = 25x - 14

Since trapezium is a part of parallelogram, then:

∠J + ∠K + ∠L + ∠M = 360°

2∠J + 2∠M = 360°

2(7x + 2) + 2(25x - 14) = 360°

14x + 4 + 50x - 28 = 360°

64x - 24 = 360°

64x = 384

x = 6

∠J = ∠K = 7x + 2

∠J = ∠K = 7(6) + 2 = 44°

∠M = ∠L = 25x - 14

∠M = ∠L = 25(6) - 14 = 136°

2. Since EFGH is an isosceles trapezoid, then:

EH = FG

4x - 27 = x + 9

3x = 36

x = 13

EG = FH

3y + 19 = 11y - 21

40 = 8y

y = 5

3. It was given that:

PQ = 27

SR = 39

WX?

WX is the mig segment, where:

Mid segment = (base + top) / 2

WX = (PQ + SR) /2

WX = (27 + 39) / 2

WX = 66/2

WX = 33

4. It was given that:

MN = 22

DC = 29

AB ?

MN is mid segment

MN = (AB + DC) / 2

22 = (AB + 29) / 2

44 = AB + 29

AB = 15

5. JK = 3x + 11

NP = 45

ML = 10x - 12

NP is mid segmet

NP = (JK + ML) / 2

45 = [(3x + 11) + (10x - 12)] / 2

90 = (3x + 11) + (10x - 12)

90 = 13x - 1

13x = 91

x = 7

ML = 10x - 12

ML = 10(7) - 12

ML = 58

6. BC = 19

GH = 9x - 3

FE = 5x + 1

GH is mid segment

GH = (BC + FE) / 2

(9x - 3) = (19 + (5x + 1)) / 2

18x - 6 = 19 + (5x + 1)

18x - 6 = 20 + 5x

13x = 26

x = 2

GH = 9x - 3

Answer:    a = 2    f(x) = x^5

Step-by-step explanation:

The rule for the function is P(t) = 170 + 680t

Let's call Julia's final position after t hours as P.

If she drove at a constant speed v (in miles per hour), then the distance traveled can be given as:

P - P0 = vt

Given that she was 170 miles east from Denver after driving for a quarter of an hour (0.25 hours), we can write the first equation:

170 = v * 0.25

v = 680

This means that her speed was 680 miles per hour.

Using this speed, we can write the second equation:

P = 680 * t

100 = 680 * t

t = 100 / 680 = 0.147

Combining the two equations, we can find the function that gives Julia's position east from Denver after t hours as:

P(t) = P0 + v * t ----- P0 = 170 i.e. her initial position

P(t) = 170 + 680 * t

So, the rule for the function P(t) is:

P(t) = 170 + 680t

P^-1(16) is the inverse of the function P(t) at the value 16.

In other words, it gives us the time t after which Julia is 16 miles east from Denver.

To find its value, we can use the equation of the function P(t):

P(t) = 170 + 680 * t

16 = 170 + 680 * t

-154 = 680 * t

t = -154 / 680

Time cannot be negative.

So, it does not exist

P^-1(-141) is the inverse of the function P(t) at the value -141.

In other words, it gives us the time t after which Julia is 16 miles east from Denver.

So, we have

-141 = 170 + 680 * t

-311 = 680 * t

t = -311 / 680

Time cannot be negative.

So, it does not exist

We simply make t the subject in P(t)

So, we have

P^-1(t) = (t - 170) / 680

Step-by-step explanation:

To solve this problem, we'll use the exponential growth formula:

P(t) = P0 * e^(rt)

Where P(t) is the population after t years, P0 is the initial population (1543), r is the growth rate (0.038), and t is the number of years (5.2).

P(5.2) = 1543 * e^(0.038 * 5.2)

Using a calculator or natural logarithm rules:

P(5.2) = 1543 * e^0.199

P(5.2) = 1543 * 1.22

P(5.2) = 1887.46

So the population will be approximately 1887.46 after 5.2 years.

In standard position, 2.280° refers to an angle in the Cartesian plane with its beginning side on the positive x-axis and its terminal side establishing an angle of 2.280° with the positive x-axis counterclockwise.

An angle is a figure in Euclidean geometry created by two rays, called the sides of the angle, that share a common termination, called the vertex of the angle. Angles created by two rays are located in the plane containing the rays. Angles are also generated when two planes intersect. These are known as dihedral angles. An angle is formed by joining two rays (half-lines) that have a shared terminal. The latter is referred to as the angle's vertex, while the rays are referred to as the angle's sides, legs, and arms.

The length of DE is  25. So correct option is (4).

In geometry, the term "parallel" refers to two lines that are equidistant from each other over their entire length and will never intersect, no matter how far they are extended. In other words, two parallel lines are parallel if they lie in the same plane and maintain the same distance between them at all times.

Since AB is parallel to DE and BD is perpendicular to both AB and DE, by alternate interior angles, we have:

angle BDA = angle DEC

Since BD is 7 and BC is 15, we have:

triangle BCD is a 7-15-17 right triangle (the Pythagorean theorem)

So, angle BDA = angle DEC = 90 - arctan(7/15) = arctan(15/7).

Also, since AB is parallel to DE, and BD is perpendicular to both AB and DE, we have:

angle ABD = angle CDE

So, by the vertical angles theorem, we have:

angle ABD = angle CDE = 90 degrees - arctan(15/7) = arctan(7/15)

Then, by the Pythagorean theorem, the length of DE can be found as:

[tex](DE)^{2}[/tex] = [tex](AB)^{2}[/tex] + [tex](BD)^{2}[/tex] = [tex]21^{2}[/tex] + [tex]7^{2}[/tex] = 441 + 49 = 490

What is the exponential equation?

In combinatorial mathematics, the exponential formula (called the polymer expansion in physics) states that the exponential generating function for structures on finite sets is the exponential of the exponential generating function for connected structures.

a. To write the exponential equation, let t be the number of years and let P be the amount of money in the account after t years. The exponential equation can be written as:

P = 7000 * (1 + 0.08)ᵗ

b. To solve for t, we need to find the number of years it takes for P to reach $30,100. We can set up an equation and solve for t:

30,100 = 7000 * (1 + 0.08)ᵗ

Dividing both sides by 7000:

30,100 / 7000 = (1 + 0.08)ᵗ

Taking the natural logarithm of both sides:

ln (30,100 / 7000) = t * ln (1 + 0.08)

Solving for t:

t = ln (30,100 / 7000) / ln (1 + 0.08)

Using a calculator, we get:

t = 21.1397

Rounding up to the nearest whole number, it will take Fred 22 years to have $30,100 for a new car.
