Answer: 40
Step-by-step explanation: -5 x -8 is 40 since the negatives cancel each other out, the product is positive :)
The 71 degree angle cuts off the arc containing the 104 degree arc and the c degree arc. Thus, 2 * 71 = 104 + c, so c = 38 degrees. Hope this helps!
Answer:
<em>1. (-1)(x^2+x-6)</em>
<em>2. (-1)(x+3)(x-2)</em>
Step-by-step explanation:
<u>Factoring</u>
It's given the trinomial
1. There is no common factor (given).
2. Factor out -1:
Each term is divided by -1:
3. Now we factor the remaining trinomial. We find two numbers whose sum is 1 and the product is -6. These are 3 and -2, thus the trinomial is:
(-1)(x+3)(x-2)
They both get their cars washed on every 60th day.
You can solve this equation by finding the lcm (least common multiple):
15 30 45 60 75 90 105
20 40 60 80 100
The lowest common multiple is 60 as it is the first multiple the two have in common.
So, in sixty days, they’ll both get their car washed again
Answer:
Step-by-step explanation:
y=4 times 1/2 to the power of x can be written symbolically as
4 4
y = 4(1/2)^x. This is the same as y = ------- or y = -------- * 2^(-x)
2^x 1
This function is a "decaying exponential."
A suitable table follows:
x 4(2^[-x]) x y
0 4(2^0) (0, 4)
1 4(2^1) (1, 8)
2 4(2^2) (2, 16)
and so on.
