How can I show that 3sin^2 x-cos^2 x=2 can be written as 4sin^2 x=3?
no answer needed, just take the points.

Answer:

-2/3

Step-by-step explanation:

Rise: 4

Run: -6

Slope = Rise over run

Slope = 4 / -6

4 / -6 = -2/3

Answer:

4833 m

Step-by-step explanation:

Given that her angle of elevation at the first recording is 47.3 at an altitude of 4900 m

We use Pythagoras Theorem to get this done

We can say that the opposite of the angle is the altitude, while the hypotenuse of the triangle, is the distance between herself and the top

Using the sine angle rule, we have

Sine 47.3 = 4900 / h

h = 4900 / sin 47.3

h = 4900 / 0.7349

h = 6668 m

This means that she was 6668 m away from the top of the mountain

She then moves 1000 m closer to the mountain top, this means that our h = 6668 - 1000

Using the same sine angle rule, we have

Sine 58.5 = o / 5668

o = 5668 * sine 58.5

o = 5668 * 0.8526

o = 4833 m

She is 4833 m above the sea level

Answer:

y=5x-12

Step-by-step explanation:

y=5x+3, and just replace the x and y to get the b. The slope is the same.

1) 3=5(3)+b

2)3=15+b

3)-12=b

4) y=5x-12

Answer: Sale Price = $84.99 (answer). This means the cost of the item to you is $84.99. You will pay $84.99 for a item with original price of $99.99 when discounted 15%. In this example, if you buy an item at $99.99 with 15% discount, you will pay 99.99 - 14.9985 = 84.99 dollars.

Answer:

if u multiply 20 times 5 u would get 100 and and if u add 20+20+20+20+20 u would get 100 so either way ur answer may be 5

Answer:

-3, +3, 7/5

Step-by-step explanation:

(5x³-7x²)+(-45x+63)=0

X²(5x-7)-9(5x-7)=0

(X²+9)(5x-7)=0

Either x²-9=0

X²=9 so x=+3 and -3

Or 5x-7=0

5x=7 so x=1.4 (or 7/5)

Answer:

y = -3x - 3

Step-by-step explanation:

Going from the point (0,3) to the point (1,0), we see that the rise (change in y) is -3 and the run (change in x) is 1.  Thus, the slope of the new line is

m = rise/run = -3/1 = -3.

Using the coordinates of the given point (-1, 0), we'll find the equation of this line in point-slope form:

y - 0 = m(x + 1), or y = -3(x + 1), or (in slope-intercept form)  y = -3x - 3

Complete Question:

Yanay gets a lot of spam calls. An area code is defined to be a three digit number from 200-999 inclusive. In reality, many of these area codes are not in use, but for this question we'll simplify things and assume they all are.

Assuming each area code is just as likely as any other, what's the probability that the area code of two back to back spam calls are 804?

Answer:

1/6400 or 0.0000015625

Step-by-step explanation:

Given

Area Codes = 200 to 999 (inclusive)

Required

Determine the probability that back to back calls have area code 804

[First, we need to calculate the totality of area codes]

Total Area Codes = 999 - 200 + 1

Total Area Codes = 800

The probability of each code is 1/800

So, the probability of having back to back code of 804 is:

Probability = 1/800 * 1/800

Probability = (1/800)²

Probability = 1/640000

Hence, the required probability is 1/640000 or 0.0000015625
