A. a B. a = b
C. a>b
D. Can't be determined

Answer:

D. Graph D

Step-by-step explanation:

First, off me know that that equation is in slope-intercept form.

Therefore, your y-intercept is (0,1)

Then you need to find the slope by using two points on a graph and using the y2-y1/x2-x1 equation.

Now you need to pay attention to the sigh. It's [tex]\leq[/tex].

That means it is greater than or equal to ur y-intercept, it must be shaded do the side of numbers greater to 1 (ur y-intercept.)

Giving you D.

The number of ways you can choose 5 beach towels from a selection of 8 to bring on vacation is a combination problem

Permutation has to do with arrangement while combination has to do with selection.

When choosing an object from other pool of object, we will have what is called combination.

From the given question, we are told that the number of ways you can choose 5 beach towels from a selection of 8 to bring on vacation, since they are selecting, hence the situation involves combination.

The margin of error for the interval (200 miles, 250 miles) is 25 miles.

An equation is an expression that shows the relationship between two or more variables and number.

The confidence interval = mean (m) ± margin of error (e) = m ± e

Hence:

m + e = 250    (1)

m - e = 200    (2)

From the both equations:

m = 225, e = 25

The margin of error for the interval (200 miles, 250 miles) is 25 miles.

Answer:

40,000

Step-by-step explanation:

I took the test

There are 40,000 possible codes that start with the prime number could Genvieve create.

For the first digit, Genevieve wants to start with a prime number.

The prime numbers between 0 and 9 are 2, 3, 5, and 7.

So, there are 4 choices for the first digit.

For the remaining four digits, she can choose any number from 0 through 9, including the prime numbers.

Since there are 10 choices for each of the four remaining digits, the total number of possible codes for those digits is 10⁴.

To calculate the total number of possible codes that start with a prime number, we multiply the number of choices for the first digit (4) by the number of choices for the remaining four digits (10⁴):

4 × 10⁴ = 40,000

Therefore, the correct answer is A) 40,000.

Solution:

Factor left side:

Write the factors to 0 to get our solution:

[tex] = > 2x + 1 = 0[/tex]

[tex] = > \boxed{ x = - \cfrac{1}{2} }[/tex]

Using translation concepts, it is found that the equation for function g(x) is given by:

[tex]y = -\frac{2}{3}|x|[/tex]

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

The parent function is given by:

f(x) = |x|.

Researching the problem on the internet, function g(x) was reflected over the x-axis, and compressed by a factor of 2/3, hence it is multiplied by -2/3(negative due to the reflection), and the equation for function g(x) is given by:

[tex]y = -\frac{2}{3}|x|[/tex]

Answer:

  50.8°

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to remind you of the relationship between side lengths and trig functions for a right triangle. Here, you are given the short side and the hypotenuse, and asked for the largest acute angle.

__

The short side is adjacent to the largest acute angle, so the relevant relation is ...

  Cos = Adjacent/Hypotenuse

  cos(β) = (2√6)/(2√15) = √0.4

The angle measure is found using the inverse cosine function:

  β = arccos(√0.4) ≈ 50.8°

The larger acute angle is about 50.8°.
