The answer is 11. don't worry, I often forget the basics too XD
Answer:
Quadrant 4
Step-by-step explanation:
Csc = 1/sin
Cos is positive in quadrants 1 and 4
Sin is negative in quadrants 3 and 4
Answer:
D=-4<0, the equation has no real solutions, it has two imaginary solutions.
Step-by-step explanation:
The quadratic equation 
has coefficients
a=1,
b=4,
c=5.
The discriminant D is the expression
Hence,
Since the discriminant is negative, the equation has no real solutions, it has two imaginary solutions.
5 rational numbers between 0.5 and 0.6 can be any 5 numbers up to any number of decimal places that lies between 0.5 and 0.6. Or, it can also be 0.5124, 0.5676, 0.588, 0.59, 0.5789.S
Given :7872 ÷ 305.
Because it's estimation. So, we need to estimate the number 7872 to 8000.
In order to divide 8000 by a number we need to estimate 305 to the 400. Because 400 is exact divisor of 8000.
If we divide 8000 by 400 we get 20.
And it's obviously less then 60000 ÷ 300= = 200.
20 < 200.
<h3>Therefore, Harrison is absolutely correct.</h3>
