Given, a = -65 and b = 8.
We have to find multiplication of them.
a is negative and b is positive. When we multiply them, we know that the multiplication of positive and negative is negative. That means 
.
So 
= 
= 
= 
So we have got the required product.
Multiplication of a and b = -520.
The correct option is option C.
Answer:
positive
Step-by-step explanation:
Using the acronym ASTC (all students take calculus), this means that if sin and tan are negative, they must be in the fourth quadrant, which means that cos is positive.
ASTC is an acronym to help students remember which of the three basic trigonometric functions are positive in which quadrants.
A: all
S: sin
T: tan
C: cos
It starts from the first quadrant: all the sin, tan, cos are positive in the first quadrant, only sin is positive in the second quadrant, only tan is positive in the third quadrant, only cos is positive in the fourth quadrant.
Since you are doing decimals, know that you are mirroring what you would do on the left side
Your decimal number: .661
The first 6, which is .6 is the tenths place
The second 6, which is .06 is the hundredths place
1 which is .001 is the thousands place
The farther you go left, the bigger the digit number value
So when rounding up, you look at the digit after the number you are rounding
So what is after the hundredths place? Its the thousandths place which is 1
Is 61 closer to 60 or 70? Since 1 is smaller than the halfway point which is 5, its closer to 60
Answer: .661 rounded to the nearest hundredths is .660 or just simply written as .66
