Answer:

I think c, - 1.8 is the answer

-1.6 (c)

My reasoning behind this is that the number would be logical considering the fact that the point is close to 0. Also, I ruled out the other choices, and here's how I did it:

I know that A is not the answer because that would make it farther back on the number line and the point B is closer to 0 than it is to 3.8 so, I know that A is not correct.

I know that B is not the answer because -5.23 would be farther behind point A which rules it out entirely.

I know that D is not the answer because 0.1 would be right after point c (0) meaning that the point can be ruled out right away.

That leaves the only logical answer to be C because it is closer to 0 but still in between points A and B.

Hope this helps and have a nice day.

Step-by-step explanation:

The solution of the equation 1/2x² + 3/8x - 2 using completing the square method are: 1.66 or -2.41.

To solve the equation 1/2x² + 3/8x -2 using completing the square method, follow these steps:

Step 1: Move the constant term to the right-hand side

1/2x² + 3/8x = 2

Step 2: Multiply both sides by 2 to clear the fraction

x² + 3/4x = 4

Step 3: Add the square of half of the coefficient of x to both sides of the equation

x² + 3/4x + (3/8)² = 4 + (3/8)²

The left-hand side is now a perfect square, specifically (x + 3/8)².

Step 4: Simplify the right-hand side of the equation

x² + 3/4x + 9/64 = 256/64 + 9/64

x² + 3/4x + 9/64 = 265/64

Step 5: Take the square root of both sides

x + 3/8 = ±√(265)/8

Step 6: Solve for x

x = -3/8 ± √(265)/8

x = 1.66 or - 2.41

Answer:

AC = 70

BG = 38

GC = 28

AE = 63

Step-by-step explanation:

The given parameters are;

The centroid of ΔABC = G

The length of FC = 35

The length of AG = 42

The length of BF = 57

The length of DG = 14

Given that the centroid is the intersection of the medians, we have;

FA = FC = 35 Definition of median line FB, (point F is the midpoint of AC)

AC = FA + FC = 35 + 35 = 70 by segment addition postulate

AC = 70

BG = 2/3 × BF = 2/3 × 57 = 38 Definition of median line BF

BG = 38

DG = 14 = 1/3 × DC Definition of median line

∴ DC = 3 × DG = 3 × 14 = 42

GC = 2/3 × DC = 2/3 × 42 = 28 Definition of median line DC

GC = 28

AG = 42 = 2/3 × AE Definition of median line AE

∴ AE = 3/2 × 42 = 63

AE = 63.

Answer:

$210

Step-by-step explanation:

(January - March) charge last year :

Unit consumed = 2000

Bill = $250

(July - September) charge last year:

Unit consumed = 600 units

Bill = $138

Billing :

Fixed charge + rate per unit ;

Let fixed charge = c ; rate per unit = m

Billing can be represented by the equation :

mx + c = y

x = unit consumed ; y = total charge

Expensive quarter:

2000x + c = 250 - - - (1)

Least expensive quarter:

600x + c = 138 - - - (2)

From (2)

c = 138 - 600x ; plug into (1)

2000x + 138 - 600x = 250

1400x = 250 - 138

1400x = 112

x = 0.08

0.08 = x = rate per unit

From ; c = 138 - 600x

c = 138 - 600(0.08)

c = 90

Fixed charge = 90

Billing equation :

y = 0.08x + 90

If insulation will reduce unit consumption by 25%

Then, consumption in most expensive quarter will be :

(100 - 25)% * 2000

0.75 * 2000 = 1500 units

Charge will be :

(0.08*1500) + 90

= $210

The to your question is that we can use the normal distribution to estimate the probability that the product will last between 16.536 and 8.054 years.


In this case, we want to calculate the probability for x = 16.536 and x = 8.054. The mean (μ) is 14.242 years, and the standard deviation (σ) is 3.978 years.

Using the formula, we can calculate the z-scores for both values:
For x = 16.536: z = (16.536 - 14.242) / 3.978
For x = 8.054: z = (8.054 - 14.242) / 3.978

Once we have the z-scores, we can look up the corresponding probabilities in the standard normal distribution table or use a calculator. Subtracting the probability for the lower z-score from the probability for the higher z-score will give us the probability that the product will last between 16.536 and 8.054 years.

Given that, Margaret drove to an appointment at 50 miles per hour. Her speed on her return was 40 miles per hour. The trip back took one quarter of an hour longer.

The question is asking to determine the distance Margaret drove to her appointment in miles. The formula used to solve the problem is as follows;

distance = speed × time Given that the distance to and from the appointment are the same. Distance to the appointment (going) = Distance from the appointment (returning)Distance = Distance Going = Distance Returning Let's determine the time it took Margaret to drive to her appointment using the formula above. Distance = speed × time Distance Going = 50 mph × t (where t represents time)Distance Going = 50tThe time it took her to drive back is (t + 0.25) since the return took one quarter of an hour longer. Distance = speed × timeDistance Returning = 40 mph × (t + 0.25)Distance Returning = 40t + 10Using the formula Distance = Distance Going = Distance Returning50t = 40t + 10Subtract 40t from both sides.50t - 40t = 10t = 10Thus, t = 1The distance going to the appointment is;Distance Going = 50tDistance Going = 50 × 1Distance Going = 50 , Margaret drove 50 miles to her appointment.Answer: Margaret drove 50 miles to her appointment.

The equation of the Ferris wheel's sinusoidal function is h(t) = 28 * sin(π/5 * (t - 15)) + 34. Using this equation, you can determine the rider's height after one hour by substituting t = 60 into the equation.

a) The equation of the axis of the function is the average of the maximum and minimum heights. In this situation, the average is (62 + 6) / 2 = 34 m. The axis represents the average or midpoint height of the Ferris wheel ride.

b) The amplitude of the function is half the difference between the maximum and minimum heights. In this case, the amplitude is (62 - 6) / 2 = 28 m. The amplitude represents the maximum deviation from the axis, which is the distance from the average height to the maximum or minimum height.

c) The period of the function is the time it takes for one complete cycle of the sinusoidal function. In this situation, the period is the time difference between two consecutive maximum or minimum heights, which is 25 min - 15 min = 10 min. The period represents the duration of one complete up-and-down cycle of the Ferris wheel.

d) The k-value in the equation represents the angular frequency, which is related to the period of the function. The angular frequency is given by k = 2π / period. So in this case, k = 2π / 10 = π / 5.

e) Since a single ride is 4 rotations of the Ferris wheel, the domain starts at t = 0 and ends at t = 4 times the period. Therefore, the domain is [0, 4(10)] = [0, 40] minutes. The range is the minimum and maximum heights, which are [6, 62] meters.

f) The sinusoidal function to model their height relative to time can be written as h(t) = A * sin(k(t - c)) + d, where A is the amplitude, k is the angular frequency, c is the horizontal shift, and d is the vertical shift. Plugging in the given values, we have h(t) = 28 * sin(π/5 * (t - 15)) + 34.

g) To determine the rider's height after one hour (60 minutes), we substitute t = 60 into the equation: h(60) = 28 * sin(π/5 * (60 - 15)) + 34. Calculating this value gives the rider's height after one hour.

The amount accumulated after 8 years is $5,781.84. Rounded to the nearest cent, this is $5,781.84.

What is an amount?

Using the formula A = \(P(1 + r/k)^{kt}\), where A is the amount accumulated, P is the principal, r is the annual interest rate, t is the number of years, and k is the number of times the interest is compounded per year, we can calculate the amount accumulated as follows:

P = $3,350 (given)

r = 6.2% = 0.062 (convert to decimal)

t = 8 (given)

k = 365 (given)

A = \(P(1 + r/k)^{kt}\)

A = \($3,350(1 + 0.062/365)^{365*8}\)

A = \($3,350(1.000170685)^{2920}\)

A = $5,781.84

It is a fundamental relationship between the three sides of a right triangle; you must use two sides in order to find the hypotenuse. many ways to make a formula for the Pythagorean theorem but the most popular one is a squared plus b squared equals c squared. there's a book and it's called the Pythagorean proposition it contains over 300 formulas for the Pythagorean theorem. a man who went by Pythagoras had found the Pythagorean theorem in the school of mathematics and Cortana he was a Greek Seaport in southern Italy he was going to get too many contributions to mathematics although some of them may have actually been the work of his students that he had taught. Pythagorean theorem is the most famous mathematical contribution in history.
