Answer:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 1010. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
7.1×1047.1×104
Answer:
1.938 x 10^3
Step-by-step explanation:
1938 move decimal 3 times to left and times by 10 to 3rd
Answer:
4/3
Step-by-step explanation:
Given two points, we can find the slope by using
m = (y2-y1)/(x2-x1)
= (20 - -16)/(7 - -20)
= (20+16)/(7+20)
= 36/27
=4/3
The given function sin x=0.5 represents a standard triangle which is same with sin x =1/2.
Where using SOH, we can get the value of the opposite leg which is O=1 and the hypotenuse is equal to H=2. Therefore, the adjacent leg is equal to A=√3.
Solving for cos x, we can use CAH and the result is shown below:
cos x = √3/2
The answer is cos x = √3 / 2.
Answer:
theta = + 2n, + 2n, + 2n, + 2n
Step-by-step explanation:
sin^2 theta - cos^3 theta = 1
cos^3 theta = 1 - sin^2 theta
sin^2 theta - cos^3 theta = 0
Substitute
sin^2 theta - ( 1 - sin^2 theta ) = 0
Distribute negative
sin^2 theta - 1 + sin^2 theta = 0
Combine same values
2sin^2 theta - 1 = 0
2sin^2 theta = 1
sin^2 theta =
sin theta = +-
Right Triangle: 1 - 1 -
theta = + 2n, + 2n, + 2n, + 2n
period of Sin function is 2
