Answer:

7. A ≈ 60.1°

8. B ≈ 34.0°

9. C ≈ 33.1°

Step-by-step explanation:

7.

The Law of Sines states that for a triangle with lengths a, b, and c and angles A, B, and C: \frac{a}{sinA}= \frac{b}{sinB} =\frac{c}{sinC}.

Here, we can say that a = 7, b = 8, and B = 82, and we want to find A. Plug these values in:

\frac{a}{sinA} =\frac{b}{sinB}

\frac{7}{sinA} =\frac{8}{sin(82)}

Solve for A:

A ≈ 60.1°

8.

Again, use the Law of Sines as above:

\frac{b}{sinB} =\frac{c}{sinC}

\frac{14}{sin(37)} =\frac{13}{sinB}

Solve for B:

B ≈ 34.0°

9.

Use the Law of Sines as above:

\frac{a}{sinA} =\frac{c}{sinC}

\frac{17}{sin(68)} =\frac{10}{sinC}

Solve for C:

C ≈ 33.1°

Answer:

7. 60.1°

8. 34.0°

9. 33.1°

Step-by-step explanation:

7. 7/sinA = 8/sin82

sinA = 7 × sin82/8

sinA = 0.8664845601

A = 60.05265736

8. 14/sin37 = 13/sinB

sinB = 0.5588282358

B = 33.97480112

9. 10/sinC = 17/sin68

sinC = 10 × sin68/17

sinC = 0.5454022674

C = 33.05215746

Which expression could represent the length of a rectangle that has an area equal to 4x2+12x?
grandymaker [24]

there are two expressions that can represent the length of the rectangle, these two expressions are:

L = x

or

L = (4x + 12)

<h3>Which expression could represent the length of the rectangle?</h3>

Remember that for a rectangle of length L and width W, the area is given by:

A = L*W

In this case, we know that the area is:

A = 4x^2 + 12x

We can factorize that expression into:

A = x*(4x + 12)

So there are two expressions that can represent the length of the rectangle, these two expressions are:

L = x

or

L = (4x + 12)

Simplify your answer to the previous part and enter a differential equation in terms of the dependent variable xx satisfied by x
rusak2 [61]

Answer:

x'-5x=0, or x''-25x=0, or x'''-125x=0

Step-by-step explanation:

The function x(t)=e^{5t} is infinitely differentiable, so it satisfies a infinite number of differential equations. The required answer depends on your previous part, so I will describe a general procedure to obtain the equations.

Using rules of differentiation, we obtain that x'(t)=5e^{5t}=5x \text{ then }x'-5x=0. Differentiate again to obtain, x''(t)=25e^{5t}=25x=5x' \text{ then }x''-25x=0=x''-5x'. Repeating this process, x'''(t)=125e^{5t}=125x=25x' \text{ then }x'''-125x=0=x'''-25x'.

This can repeated infinitely, so it is possible to obtain a differential equation of order n. The key is to differentiate the required number of times and write the equation in terms of x.
