Answer:

Step-by-step explanation:

1. sin 241 = sin(61 + π) = -sin61 = -t^(1/2)

2. sin^2 + cos^2 =1, cos 61= (1-t)^(1/2)

3. [2sin^2 (x)sin(x) +2cos^2 (x)sin(x)]/2cos(x) = 2sin(x) / 2cos(x) = tan(x)

4. tan (x), x do not equal to （π/2 +or- kπ）

x do not equal to 90，270。

Answer: 36

Step-by-step explanation:

Multiply -6 by itself six times, then divide 1 by -6 four times. Multiply the products. Then multiply -6 by itself one more time and you will get 36.

The top question is 1/4. There seems to be a small multiplaction symbol next to the fractions, I'm ignoring that. To get 1/4, I multiplied 2 by itself six times because of the exponent, to get 64. I did the same with the bottom, and recieved 256. 64/256 is 1/4.

So it’s $15 per month so that is what you are gonna multiply by x. You start out with $75 so that’s the initial fee. 15x + 75 is your expression.

A student earned grades of C, A, B, and A. Those courses had these corresponding numbers of credit hours: 44, 66, 11, and

asambeis [7]

Answer:

The grade point average of the student is 49.92.

Step-by-step explanation:

A student earned grades : C, A, B, and A

Corresponding numbers of credit hours : 44, 66, 11, and 66

Assigns quality points to letter grades :

A = 4 , B = 3 , C = 2 , D = 1 , F = 0

The grade point average (GPA):

$\frac{\sum (\text{grade point}\times \text{credit hours})}{\sum (\text{grade point})}$

$=\frac{2\times 44+4\times 66+3\times 11+4\times 66}{2+4+3+4}$

$=\frac{649}{13}=49.9230\approx 49.92$

The grade point average of the student is 49.92.

Hello, happy Friday, I am just here with some geometry questions.

klasskru [66]

Answer:

U'(-14, 8)

Step-by-step explanation:

The transformations include:

T<-2,2>·D3

This is a dilation by a scale factor of 3 and then translation 2 units left and 2 units up.

The transformation applied to the point U:

U(-4,2) → U'(-4*3 - 2, 2*3 + 2) = U'(-14, 8)
