The answer is C because you should look if it’s an open circle and which way the arrow is facing.

Given cos 0 = 1/6 and angle 0 is in Quadrant IV, what is the exact value of sin 0 in

Vinil7 [7]

cos 0 = 1/6

1 - cos²0 = sin²0

sin²0 = 35/36

in quadrant IV (4) the cos is positive sin is negative.

sin0 = - √35/6

Which ratios are equivalent to 10:16? Check all that apply. 30 to 48 25:35 StartFraction 40 Over 64 EndFraction 8:32 5 to 15

schepotkina [342]

Answer:

30 to 48, 40/64

Step-by-step explanation:

Which ratios are equivalent to 10:16, and they gave us 30 to 48, 25:35, 40/64, 8/32 and 5 to 15.

For 30 to 48, we can mulitply the 10:16 by 3 to give us 30:48, so it is equal.

For 25:35, we simplify it to 5:7, while 10:16 is 5:8, so they are not equal.

For 40/64, we can take 10:16 and multiply them by 4, getting the same number. Therefore, it is equal.

For 8/32, we can simplify it down to 1/4, while 10:16 simplifies down to 5:8, it is not equal.

Lastly, for 5 to 15, w can simplify that to 1/3, and get 5:8 for 10:16, so it won't be equal.

The first three terms of a sequence are given round to the nearest thousand if necessary 204,200,196 find the 31 st term

yanalaym [24]

Answer:

The 31st term is 84

Step-by-step explanation:

Here, we want to calculate the 31st term of the sequence

Firstly, we need to determine the type of sequence herein

As we can see;

200-204 = 196-200 = -4

The relationship between the numbers is a sum, that means the sequence is arithmetic

and; -4 represents the common difference

Mathematically, the nth term of an arithmetic sequence can be calculated using the equation;

Tn = a+ (n-1)d

with respect to the question;

a is the first term = 204

n = 31 and d = -4

Substituting these numbers;

T31= 204 + (31-1)-4

T31 = 204 - 4(30)

T31 = 204 - 120

T31 = 84
