The discriminant of the quadratic equation 2x + 5x2 = 1 is 24.

--

Use this formula

Plug in

You get 24

Answer:

24

Step-by-step explanation:

Discriminant

b² - 4ac   (when ax² + bx + c = 0)

Assuming the given equation is:   2x + 5x² = 1

Rewrite the equation so that it equals zero:

⇒ 5x² + 2x - 1 = 0

Therefore,  a = 5    b = 2    c = -1

Input these into the discriminant formula and solve:

⇒ 2² - 4(5)(-1) = 4 + 20

                      = 24

Therefore, the discriminant of the quadratice equation is 24.

The thermometer reading would be 73.48°C.

The boiling point of water is generally considered to be 100°C. According to the given information, the temperature of the liquid in the thermometer is 26.52°C lower than the boiling point of water. Therefore, to find the thermometer reading, we subtract 26.52 from 100.

100 - 26.52 = 73.48

Hence, the thermometer reading would be 73.48°C.

In this scenario, we are assuming that the thermometer is calibrated to measure temperature in Celsius. The boiling point of water at standard atmospheric pressure is 100°C, and the given information states that the liquid in the thermometer is 26.52°C lower than the boiling point.

By subtracting 26.52 from 100, we obtain a reading of 73.48°C.

Thermometers work by utilizing the principle that certain substances, such as mercury or alcohol, expand or contract with changes in temperature. The expansion or contraction is measured using a scale, which is marked with various temperature values.

In this case, the thermometer is calibrated in Celsius, so we refer to the Celsius scale. By subtracting 26.52 from 100, we find the temperature at which the liquid in the thermometer is settled, which is 73.48°C.

Answer:

Rounded to the nearest hundredths, the volume of the cylinder is approximately 58.91 cm^3.

Step-by-step explanation:

To find the volume of a cylinder, you need to know its radius (r) and height (h). In this case, the radius is given as 5 cm and the height is 0.75 cm.

The formula for the volume of a cylinder is:

V = π * r^2 * h

where π is a mathematical constant approximately equal to 3.14159.

Let's substitute the given values into the formula:

V = π * (5 cm)^2 * 0.75 cm

V ≈ 3.14159 * (25 cm^2) * 0.75 cm

V ≈ 58.909 cm^3

The percent y (in decimal form) of battery power remaining x hours after you turn on a laptop computer is given by

Let us graph the above equation

a. What is the x-intercept? What does it represent?

The x-intercept is the point where the line intersects the x-axis.

From the graph, we can see that the x-intercept is (5, 0)

The x-intercept represents that it takes 5 hours for the battery power to go to 0%

You can manually find out the x-intercept by substituting y = 0 into the given equation

Therefore, the x-intercept is (5, 0)

b. What is the y-intercept? What does it represent?

The y-intercept is the point where the line intersects the y-axis.

From the graph, we can see that the y-intercept is (0, 1)

The y-intercept represents that the battery power is 1 (100%) when x = 0 hours.

You can manually find out the y-intercept by substituting x = 0 into the given equation

Therefore, the y-intercept is (0, 1)

c. After how many hours is the battery power at 75%

We need to substitute y = 0.75 (that means 75%) into the equation to find out x (number of hours)

Therefore, after 1.25 hours, the battery power is at 75%

d. what is the percentage of battery power remaining at 3 hours?​

We need to substitute x = 3 hours into the equation to find out y (remaining battery power)

Therefore, the remaining battery power is 40% after 3 hours.

Answer:

Depends.

If you defined \(cos\ \theta\) and \(sin\ \theta\) based on the unit circle, as in the coordinates of the point at a distance of \(\theta\) from the point \((1;0)\) measured counterclockwise along the circle, then. it's proven by the fact that since that points sit on a circle of center the origin and radius 1, it's coordinates needs to satisfy the equation \(x^2+y^2 = 1\).

If you define them based on right triangles, as in the ratios between adjacent (cosine) or oppsite (sine) sides and the hypotenuse, then it's simply applying the Pythagorean theorem. In particular let a be the hypotenuse of a right triangle of which one of the angles measures \(\theta\), let b the adjacent side to said angle, and c the opposite side.

By definition, \(\frac ba = cos\ \theta ; \frac ca = \sin\ \theta\). clearing denominators we get \(b= a\cdot\cos\ \theta; c= a\cdot sin\ \theta\), and applying the Pythagorean theorem:

\(a^2= b^2+c^2 = (a\cdot\cos\ \theta)^2 + (a\cdot sin\ \theta)^2\) And, taking the first and last step in this chain, dividing everything by \(a^2\) which is obviously non-zero we're left with \(1= cos^2\theta + sin^2\theta\), QED.

A formula for y in terms of x and c is y = c⁵√x

In inverse variation, as the value of one of the variables increases, the value of the other decreases and as the value of one of the variable decreases, the other increases.

From the information given, we have that;

y ∝1/√x

Now, let's find the constant value, k, we have;

y√x = k

We have that their values are;

y = c⁴, x = c²

Substitute the values, we have;

c⁴√c² = k

k = c⁵

The time take to fill the pool will be 494 hours.

Inlet pipe fills in  38 hours = 1 pool

Inlet pipe fills in 1 hours = 1/38

Drain pipe empty in 39 hours = 1 pool

Drain pipe empty in 1 hour = 1/39

If both pipes are opened together then in pool fills in 1 hour =  1/38 - 1/39

= 1/1482

Therefore, 1/1482 fills in 1 hour.
