Answer:

B. 34°

Step-by-step explanation:

We have been given an image of a triangle and we are asked to find the measure of angle K.

We will use law of sines to solve our given problem.

\frac{Sin(A)}{a}=\frac{Sin(B)}{b}=\frac{Sin(C)}{c}, where, a, b and c are sides corresponding to angle A, angle B and angle C respectively.

Upon substituting our given values in above formula we will get,

\frac{Sin(K)}{2.7}=\frac{Sin(105^{\circ})}{4.7}

Upon multiplying both sides of our equation by 2.7 we will get,

\frac{Sin(K)}{2.7}\times 2.7=\frac{Sin(105^{\circ})}{4.7}\times 2.7

Sin(K)=\frac{0.965925826289}{4.7}\times 2.7

Sin(K)=0.2055161332529787\times 2.7

Sin(K)=0.55489355978304249

Now we will use arcsin to find the measure of angle K.

K=Sin^{-1}(0.55489355978304249)

K=33.703383757351^{\circ}

Upon rounding our answer to nearest whole number we will get,

K\approx 34^{\circ}

Therefore, the measure of angle K is approximately 34 degrees and option B is the correct choice.

The value, V(m), of a comic book m months after publication has an average rate of change of –0.04 between m = 36 and m = 60. Wh
german

Answer:

C. The value of the comic book decreased by an average of $0.04 each month between m = 36 and m = 60.

Step-by-step explanation:

The average rate of change for the function f(x) from x_1=a and x_2=b is

\dfrac{f(b)-f(a)}{b-a}

It is a measure of how much the function changed per unit, on average, over that interval.

Actually, this is the slope of the line passing through two points on the graph of the function.

If the average rate of change of the function f(x) between m = 36 and m = 60 is -0,04, it means that the value of the comic book decreased (because of negative number -0.04) by an average of $0.04 each month (a unit in this case is a month) between m = 36 and m = 60.

What is the volume of the sphere shown below??<br> R=13
kvasek [131]

Here is your answer

D. \frac{8788}{3}π {units}^{3}

REASON:

Formula for volume of sphere

= 4/3×π× r^3

Here, r= 13

So,

volume=4/3×π× 13^3

= 4/3×π× 2197

= 8788/3 ×π
