What is the answer? x^2-y^2=55

Mathematics
1 answer:
LenKa [72]3 years ago
3 0

Answer:

To solve for x we can write:

x² - y² = 55

x² = y² + 55

x = ±√(y² + 55)

To solve for y:

x² - y² = 55

y² = x² - 55

y = ±√(x² - 55)

valentina_108 [34]

Answer:

The answer is 1/n⁴. option 2.

Step-by-step explanation:

1) You have to use the Quotient rule.

{n}^{6 - 10}

2)Then, Simplify 6 - 10 to -4.

{n}^{ - 4}

3) And lastly you have to use the negative power rule:

\frac{1}{ {n}^{4} }

And Therefor, the answer is, 1/n⁴.

The equation that represents the relationship between the number of liters, x, and the number of liquid pints, y is y = 2.11x

<h3>How to determine the equation?</h3>

The attached table of values represents the missing piece in the question.

Start by calculating the rate of change using:

m = (y2 - y1)/(x2 - x1)

This gives

m = (14.77 - 10.55)/(7- 5)

Evaluate

m = 2.11

The equation is then calculated using:

y = m(x - x1) + y1

This gives

y = 2.11(x - 5) + 10.55

Evaluate

y = 2.11x - 10.55 + 10.55

y = 2.11x

Hence, the equation that represents the relationship between the number of liters, x, and the number of liquid pints, y is y = 2.11x

Find y if the line through (3, 1) and (9, y) has a slope of 4.
klio [65]

Answer:

y = 25

Step-by-step explanation:

To find slope, we use this expression: \frac{y2-y1}{x2-x1}

Since we already know the slope and are trying to figure out a y-value, we can input all of the values we do know in the expression and solve for the missing y.

\frac{y-1}{9-3}=4

Simplify the denominator:  \frac{y-1}{6}=4

Multiply both sides by 6 to isolate the y - 1:   y - 1 = 24

Add 1 to both sides to isolate the y:  y = 25

y = 25

An advertisement for a circular rug says that the rug has a diameter of 6 feet. Find the relative error of this measurement
Aleonysh [2.5K]

Answer:

1. 8.3%

Step-by-step explanation:

Relative error = absolute error/expected measurement

The expected measurement is given as 6 ft.

Now, the absolute error is usually equal to half of a unit of the measure.

This means the absolute error in this case is ½ × 1 = 0.5 ft

Thus, the exact measurement will be;

6 ± 0.5

Thus;

Relative error = 0.5/6

Relative error = 0.083

Expressing it in percentage gives 8.3%
