Which is a secant? CT MH CD

Mathematics

<h2>Answer:</h2>

The secant in the given figure is:

                                  CD

<h2>Step-by-step explanation:</h2>

We know that in geometry a secant is a line that intersect the circle or any curve in atleast two distinct points.

Here we have a curve as a circle.

Hence, the secant is:  CD

( Also   MH is not a secant since it does not intersect the curve at any point.

Also   CT is not a secant because it is not a line, it is a line segment although it intersect the curve at two distinct points )

Wind farms are a source of renewable energy found around the world. The power P (in kilowatts) generated by a wind turbine varie
kodGreya [7K]

Answer:

New power = 88 Kw (Approx.)

Step-by-step explanation:

Given:

P = a(v³)

Old power p = 700 Kw

Old wind speed v = 12 m/s

Find:

New power when v = 6m/s

Computation:

P = a(v³)

700 = a(12³)

a = 0.4050 m²

New power = a(v³)

New power = (0.4050)(6³)

New power = 87.48

New power = 88 Kw (Approx.)

The length and width of a rectangular room are measured to be 3.955±0.005m. Calculate the area of the room and its uncertainty i
Margarita [4]

Answer:

The area of the room and its uncertainty in square meters is:

15.642±0.040 m^2

Step-by-step explanation:

We know the area of a rectangular room is the multiplication of the length and width:

Area= 3.955m*3.955m\\Area= 15.642 m^2

Now we need to know the uncertainty, the uncertainty of a multiplication is:

\frac{δ_a}{|Area|} =\frac{δ_L}{|L|}+\frac{δ_W}{|W|} (1)

δ_A: Area uncertainty

δ_L: Length uncertainty

δ_W: Width uncertainty

A: Area of the room

L: Length

W: Width

Clearing the uncertainty of the area:

δ_A=(\frac{δ_x}{|x|}+\frac{δ_y}{|y|})*Area (2)

δ_A=(\frac{0.005}{|3.955|}+\frac{0.005}{|3.955|})*15.642 m^2

δ_A= 0.040 m^2

The area of the room and its uncertainty in square meters is:

15.642±0.040 m^2

Write an equation that can be used to solve the following: The sum of a number, n, and a number 5 larger than it is 41.
navik [9.2K]

n + n + 5 = 41 (4) 5n + n + 1 = 41

<em>n and "5 larger than n" </em>

'5 larger than n' = equivalent to n + 5

We now have n + n + 5

The problem says 41, thus;

<em>n + n + 5 = 41</em>
