The sample size of this two-stage experiment would be 1 fair coin and 1 deck of cards; 1 half deck of only clubs and spades, and one half deck of only hearts and diamonds.
I think the answer would be A
Tangent is the ratio opposite/adjacent
tan(angle) = opposite/adjacent
tan(x) = 8/5
tan(x) = 1.6
x = arctan(1.6)
x = 57.9946
x = 58 degrees which is the answer
The answer is approximate to the nearest whole number. Make sure your calculator is in degree mode.
Well in order to get a factor you have to set the 2 x seperat and the last number too.. this will give you (x )(x ) they are both negative so one sign has to be a positive and the other a negative, lets find out what can we seperate the last term to, well lets see what numbers multiplied that give you -16 when adding or subtracting it gives you -6
E.J. 4 times -4 is 16 but when adding or subtracting it give you 0
lets try this 8 and 2 wehn multiplied it gives you 16 and when adding or subtracting it gives you eitehr 10 or 6!! Wow 6 that is what you need in order to get the factors of the trinomial.... SO now our factors look like (x 2)(x 8), our last step is to find out where the signs go, well if we know that the 6 is negative then we want to make our largest number a negative, this means 8 is negative so 2 will be positive so our factors now are (x+2)(x-8)... now which of these are in your choices?? well only the (x+2) so your second option would be the answer...
Hope this helps
Answer:
- Hypotenuse
- Leg 1
- Leg 2
Step-by-step explanation:
Represent the dimensions as:
So, we have:
Required
Determine the dimensions
Apply Pythagoras theorem
This gives:
Open bracket
Collect Like Terms
Solve for S2
Recall that:
Hence, the dimensions are:
