Answer:
.071 times 101
Step-by-step explanation: The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease.
Answer: -2
Step-by-step explanation:
since there are no multiplication you can simply go from left to right doing simple math. You start from a +4 that would be a positive 4, you subtract -3 so you get +1 then you subtract -4 and the result is -3 (negative 3) so now you are currently working with numbers lower than 0, adding +2 will make it -1 and finally you subtract for -1 and that will make it -2. Hope it's what u needed
Step-by-step explanation:
The union of two sets contains all the elements contained in either set,
The intersection of two sets contains only the elements that are in both sets.
A.) f(x) = x^2 because 2 > 1. So f(2) = 4.
A is correct.
B.) f(x) = x^2 because 5 > 1. So f(5) = 25.
B is incorrect.
C.) f(x) = 2x because -2 < 1. So f(-2) = -4.
C is incorrect.
D.) f(x) = 5 because x = 1.
D is correct.
So the answer is A and D.
The 20 represents the specific section, the 8 adds onto that side making the full side 8.
-> See attached
Using this, we can set up a proportion to solve;
<em>Sides of the smaller triangle are on the top, and sides of the larger triangle are on the bottom</em>
[Proportion we made]
[Cross-multiply]
20x = 140
[Divide both sides of the equation by 20]
x = 7 ✓
This is how they reached 7, I hope this answer explains it so you can understand.
Have a nice day!
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.
