Answer:

$615

Step-by-step explanation:

50 points please give step by step instruction

Answer:

 x = 90, 199.5, 270, 340.5 degrees

Step-by-step explanation:

cos2x + 2sinx = sin^2x

Change cos2x to 1 - 2sin^2x:

1 - 2sin^2x + 2 sinx = sin^2x

Shift the terms to make it a quadratic equation:

3 sin^2x - 2sinx - 1 = 0

Factorise the quadratic equation:

(sinx - 1)(3sinx + 1) = 0

sin x = 1 or sin x = -1/3

Solve for sin x = 1:

From graph of sin x, x = 90 and 270 degrees when sin x = 1.

x = 90, 270 degrees

Solve for sin x = -1/3

Sin x = -1/3

Basic angle = sin inverse (1/3)

= 19.471 degrees

Since sin x < 0, x is in the 3rd or 4th quadrant

x = 180 + 19.471, 360 - 19.471

x = 199.5, 340.5

Hence, x = 90, 199.5, 270, 340.5 degrees

Which situation could this graph represent?

HACTEHA [7]

Situation: The answer is D because running up a hill first takes less time, which you can see in the graph. Then, walking up a hill takes more time and you are going upward, which is expressed in the graph. Next, you run down the hill, which takes less time than walking which is on the graph. Finally, you walk the remainder of the hill downwards, which takes more time and is shown in the graph. Hope this helps!

Solve the proportion

Vinvika [58]

Answer:

1. (3/2)

2. (20)

3. (3)

4. (-9/5)

5. (-8/7)

6. (-2/3), (4)

Step-by-step explanation:

1. 2. 3. 4.

x 3 12 3 x 1 x + 3 3

/ = / / = / / = / / = /

4 8 x 5 9 x 2 5

8x = 12 60 = 3x x² = 9 5x + 15 = 6

÷8 ÷8 ÷3 ÷3 x = √9 -15 -15

5x = -9

x = (3/2) x = 20 x = 3 ÷5 ÷5

x = (-9/5)

5. 6.

4 - x 3 1 x - 3

/ = / / = /

12 7 2x + 1 9

28 - 7x = 36 9 = 2x^2 - 5x - 3

-28 -28 + 3 + 3

12 = 2x^2 - 5x

-7x = 8 -12 -12

÷-7 ÷-7

2x^2 - 5x - 12 = 0

x = (-8/7)

-b +-√b^2 - 4ac

/ = -(-5)√-5^2 - 4 (2)(-12)

2a /

2(2)

= 5-+√121 5 - 11 -6

/ = / = / = (-2/3)

-4 4 4

= 5 + 11 16

/ = / = (4)

4 4

I hope this helps!
