Given:

ABC is a right triangle.

Opposite of C = AB = 6

Adjacent of C = BC = 8

Hypotenuse = AC = 10

To find:

The value of sin C.

Solution:

Using basic trigonometric ratio formula:

$$\sin \theta = \frac{\text{Opposite of }\theta}{\text{Hypotenuse}}$

$$\sin C = \frac{\text{Opposite of C}}{\text{Hypotenuse}}$

$$\sin C = \frac{AB}{AC}$

$$\sin C = \frac{6}{10}$

Cancel the common factors.

$$\sin C = \frac{3}{5}$

The value of sin C is $\frac{3}{5}$ .

The voltage across the capacitor increases as a function of time when an uncharged capacitor is placed in a single loop with a r

dmitriy555 [2]

Answer:

1. Exponential

Step-by-step explanation:

The simplest RC-Circuit, that is, a capacitor and a resistor in a series configuration can be modeled by using Ohm's Law and Kirchhoff's Circuit Laws:

$C \cdot \frac{dV}{dt} + \frac{V}{R} = 0$

By rearranging the formula, an homogeneous linear first-order differential equation is found:

$\frac{dV}{dt} + \frac{1}{R \cdot C} \cdot V = 0$

Whose solution has the form of a exponential model:

$V(t) = V_{o} \cdot e^{-\frac{t}{R \cdot C} }$

Select the three ratios that represent the numbers of blue marbles to red marbles, there are 6 blue marbles and 9 red marbles

Agata [3.3K]

Answer:

6:9 or (2:3)

Step-by-step explanation:

A ratio is a term that gives comparison of values. It helps to determine

how much of a particular thing that is compare to other thing.

Given:

numbers of blue marbles= 6

numbers of red marbles= 9

Hence, ratios that represent the numbers of blue marbles to red = 6:9

We can reduce it using factor of 3, hence the ratio becomes(2:3)
