How do you write 1.74 as a mixed number?
Mnenie [13.5K]
The 1 is ur whole number because it is to the left of the decimal.
0.74....the last digit (4) is in the hundredth place...so put the 74 over 100.
74/100 reduces to 37/50.

Rewrite with only sin x and cos x. <br> sin 2x - cos 2x
Natali5045456 [20]
Making use of the following identities
sin 2x = 2 sin x cos x
cos 2x = 2 cos^2x - 1
we can write:
sin\ 2x-cos\ 2x=2\ sin\ x \cos\ x-2\ cos^{2}x+1 ..............(1)
Equation (1) can be factorized to give, on the right hand side:
2 cos x(sin x - cos x) + 1

Find the volume of a pyramid with a square base, where the side length of the base is
valina [46]

Answer:

Volume = 1114.1 in^3

Step-by-step explanation:

Recall that the formula for the volume of a pyramid is given by:

Volume=\frac{1}{3} \,B\,*\,H

where B is the area of the pyramid's base (in our case a square of side 12,8 in), and H the pyramid's height (in our case 20.4 in).

Then the square base of the pyramid has an area given by: (12.8\,\,in)^2=163.84\,\,in^2

Finally,we can now write the volume of the pyramid as:

Volume=\frac{1}{3} \,B\,*\,H\\Volume=\frac{1}{3} \,(163.84)\,*\,20.4\,\,in^3\\Volume=1114.112\,\,in^3

Rounding the answer to a tenth of a cubic inch, we get:

Volume = 1114.1 in^3
