In the half-angle formula for sine and cosine, notice that a plus/minus sign appears in front of each radical (square root). Whether your answer is positive or negative depends on which quadrant the new angle (the half angle) is in

Can someone help me find the median of this question please.
vodomira [7]

Answer:

median = 2.8 m

Step-by-step explanation:

the median is the middle value of the data set in ascending order.

If there is no exact middle value then it is the average of the values either side of the middle.

the stem- leaf diagram shows the data in ascending order from 1.6 to 4.5

there are 10 data values so no exact middle value.

the median lies between 2.7 and 2.9

median = (2.7 + 2.9) ÷ 2 = 5.6 ÷ 2 = 2.8 m

Simplify the given expression. Assume that no variable equals 0. (14x20y10 / 28x12y14)4
liq [111]

Answer:

\frac{1}{2^{4}*14^{3} *x^{28}*y^{46}}

Step-by-step explanation:

To simplify the expression \frac{14x^{20}y^{10}}{(2*14*x^{12} y^{14} )^{4}} first we need to raise every member of the denominator to the given exponent, number 4

Remember that (x^{b} )^{c} =z^{b*c} where 'a' and 'b are natural numbers (any numbers you want

\frac{14x^{20}*y^{10}}{2^{4}*14^{4}*x^{48}*y^{56}}

Where we can make some operations, remember that \frac{x^{a} }{x^{c} }=x^{a-c}

\frac{1}{2^{4}*14^{3} *x^{28}*y^{46}}

We have assumed that nor x, nor y equals 0 in any moment, since if that would happen, we ca not simplify anything bacause error math 0/0.

The length of a rectangle is 2 times the width. If the perimeter is to be less than 96 meters. What are the possible
tiny-mole [99]

Answer:

W>16

Step-by-step explanation:

The formula for calculating the perimeter of a rectangle:

P = 2L+2W

L is the length of the rectangle

W is the width of the rectangle:

Given

P = 96m

If the length of a rectangle is 2 times the width, then L = 2W

Substitute into the formula:

Since the perimeter is less than 96m

96 < 2(2W)+2W

96 < 4W+2W

96 < 6W

Divide both sides by 6:

96/6 < 6W/6

16 < W

W>16

Hence the possible values of the width are all values greater than 16.
