Answer:
The answers A, B, and C all work for this problem. The answer D is the only one that does not.
Step-by-step explanation:
When looking at two parenthesis being multiplied together and being equal to 0, we know that at least one of the parenthesis must be equal to 0 for it to be true. In A and C, the first parenthesis will be equal to 0 due to a = -6.
(a + 6)
(-6 + 6)
(0)
And in B, we can see that the second parenthesis would be equal to 0 due to b = 1
(b - 1)
(1 - 1)
(0)
Now we can try the D options, but will note that they do not work for either parenthesis.
(a + 6)(b - 1)
(0 + 6)(0 - 1)
(6)(-1)
There is no different in both of them. if you used both of them in a math problem you would still get the same answer as if you use the other one.
Answer:
a) 4 1/10 slices eaten
b) cannot be solved because we don't know how many slices in each pizza
Step-by-step explanation:
5*1/10=5/10
12*3/10=36/10
36/10+5/10=41/10
41/10=4 1/10 slices
ANSWER :
The answer is :

EXPLANATION :
Note that cotangent is only positive when the angle is in the first or third quadrant.
Since y is not in the first quadrant, it must be in the third quadrant.
So the x and y are both negative.
An angle with a terminal point (x, y)
The cotangent is x/y
We can equate :

Since x and y are both negatives, x = -9 and y = -13
We can have the triangle :
The hypotenuse will be :

We are asked to find the value of sec y.
In an angle with a terminal point (x, y)
The secant is :

The hypotenuse is 5√10 and x = -9
The value of sec will be :
