Answer:
1) 
2) 
3) 
4) 
Step-by-step explanation:
1) Value of
since sin45° = 1/√2
Therefore 
2).Value of 
Since cos 30° = √3/2
Therefore 
3). Value of 
since tan 60° = √3
therefore 
4). Value of 
Since sin90°=1
Therefore 
We could answer this if we were able to see the other questions. ;-;
To evaluate this expression, we simply plug the value of the variable into the expression and solve.
Since m = -4, plug a -4 in for m every time the m appears in the expression.
So we have (-4)^2 + 6(-4) + 3.
Start by simplifying the exponent.
(-4)^2 is 16.
Now multiply.
A positive times a negative is a negative.
So 6(-4) is -24.
So we have 16 + 24 + 3 which is 43.
This line has a slope of
1
2
(same as the first one), but a different y-intercept. These two lines are parallel.
hope you have a good day!
The probability that one of the children will be a boy is 75%. This is because if the other 3 children were girls, there is no longer a 50% chance there will be a girl. The more girls, the lower the probability.
