Answer 1

Hello!

[tex]\large\boxed{\frac{\pi }{4} < x < \frac{5\pi }{4}}[/tex]

To begin, we can solve the inequality:

sin(x) > cos(x)

Divide both sides by cos(x):

sin(x) / cos(x) > 1

tan(x) > 1

x > π/4

However, we can also solve it the other way to produce the end to the interval:

sin(x) > cos(x)

1 > cot(x)

x < 5π/4

Therefore, sin(x) > cos(x) on the interval π/4 < x < 5π/4.

Answer 2

Answer:

π/4 < x < 5π/4.

Answers

Step-by-step explanation:

Let x = log7(49^w).

We have 7^x = 49^w.

=> 7^x = (7^2)^w

=> 7^x = 7^2w.

=> x = 2w.

Therefore log7(49^w) = 2w.

Kara earns 12 cent for each paper she delivers. If she delivers papers to 42 customers each day, how much does she earn in 1 week ?

Answers

12x42=504

504 cents earned every day when 42 papers are delivered

For a week= 504x7

3528cents

Answer:

3,528 cents = 35 dollars and 28 cents

Step-by-step explanation:

She earns 12 cents for each paper delivered.

=> She earns: 12 x 42 = 504 cents a day

=> She earns: 12 x 42 x 7 = 3528 cents in 1 week.

That is probably the answer you're expecting.

But you shouldn't.

One customer might need more than 1 paper a day, so there's no clear answer to your question.

Answer:

x = 30°

Step-by-step explanation:

Given that,

∠A = x°

∠B = 2x°

∠C = 90°

We need to find the value of x.

We know that the sum of angles of a triangle is equal to 180°.

ATQ,

x° + 2x° + 90° = 180°

3x° = 180°-90°

3x° = 90°

x° = 30°

So, the value of x is 30°.

Answer:

3x+90=180

3x=90

x=30

Which distribution is most nearly appropriate to describe_______the number of fatalities in Texas in a given year due to poisonous snakebites.

Answer: Poisson distribution

Step-by-step explanation:

The Poisson distribution simply measures the chance for an event occuring based on a particular period of time. It is typically useful for finding the probability of events that have low probabilities of occuring.

Therefore, the distribution that will be ideal in knowing the number of fatalities in Texas in a given year due to poisonous snakebites is the poisson distribution.

By Exterior Angle Theorem,

81° + b = 117°.

=> b = 117° - 81° = 36°.

Answer:

b = 36

Step-by-step explanation:

a+117 = 180 ( being straight angle)

a = 180 - 117

a = 63

Now,

81 + 63 + b = 180 ( being sum of interior of triangle)

144 + b= 180

b = 180 - 144
