14 people  chose the tiger  and this equals 100-72 = 28%

So the percentage who shose the eag;e and the polar bear = 17/14 * 28  = 34%

So 100 - 28 - 34 = 38% chose the Viking  This equals  38 * 0.5 =19 students.<---- Answer

Total number of students =  100 * 0.5 = 50. answer

Answer:

19 students chose viking.

Step-by-step explanation:

Jesse spilled water on the paper but he knows that 72% of the students chose a mascot other than a tiger.

11 people chose the eagle six people chose the polar bear 14 people chose the tiger.

Let the total students be = x

And 14 people chose tiger this means only 28% students chose tiger.

0.28x=14

x=50

Hence, total students are 50.

Now, out of 50, 14 chose tiger, 11 chose eagle, 6 chose polar bear. Total are : 14+11+6=31

Hence, 50-31=19 students chose Viking.

<h3>Answer: Choice D)  31.2 miles</h3>

This value is approximate.

============================================================

Explanation:

Let's focus on the 48 degree angle. This angle combines with angle ABC to form a 90 degree angle. This means angle ABC is 90-48 = 42 degrees. Or in short we can say angle B = 42 when focusing on triangle ABC.

Now let's move to the 17 degree angle. Add on the 90 degree angle and we can see that angle CAB, aka angle A, is 17+90 = 107 degrees.

Based on those two interior angles, angle C must be...

A+B+C = 180

107+42+C = 180

149+C = 180

C = 180-149

C = 31

----------------

To sum things up so far, we have these known properties of triangle ABC

  • angle A = 107 degrees
  • side c = side AB = 24 miles
  • angle B = 42 degrees
  • angle C = 31 degrees

Let's use the law of sines to find side b, which is opposite angle B. This will find the length of side AC (which is the distance from the storm to station A).

b/sin(B) = c/sin(C)

b/sin(42) = 24/sin(31)

b = sin(42)*24/sin(31)

b = 31.1804803080182 which is approximate

b = 31.2 miles is the distance from the storm to station A

Make sure your calculator is in degree mode.

Find cscθ.<br><br>pls answer
ExtremeBDS [4]

Answer:

The answer to your question is csc Ф = \frac{-5}{4}

Step-by-step explanation:

Process

1.- Determine the sign

We must determine csc Ф in the forth quadrangle, here csc is negative.

2.- Determine the hypotenuse

     c² = a² + b²

     c² = 3² + (-4)²

     c² = 9 + 16

     c² = 25

     c = 5

3.- Determine csc Ф

    csc Ф = \frac{hypotenuse}{opposite side}

    csc Ф = \frac{5}{-4}  = \frac{-5}{4}

Step-by-step explanation:

must use PEMDAS (order of operations)

step 1: multiply 7 and 6

8 + 42 / 3 x 3

step 2: divide 42 by 3

8 + 14 x 3

step 3: multiply 14 and 3

8 + 42

Add to get 50

Determine whether the improper integral converges or diverges, and find the value of each that converges.
Vanyuwa [196]

Answer:

The integral diverges

Step-by-step explanation:

Consider the integral from 0 to infinity of

xe^{4x}

We can do this in parts

\int {xe^{4x} } \, dx =\int {x} \, d(e^{4x})/4\\ = x/4 e^{4x}-e^{4x}/16

When we substitute limits infinity we find that the values become infinity

Hence the integral diverges

The given improper integral diverges
