The answer is (20,0). We can determine the sum of two vector points by adding x1 to x2 and y1 to y2. This is like adding integers, the only difference is the answer is in vector form. In here, we have (x,y). x = 7+13 and y = 5+(-5). that is why we have the (20,0) as the answer.
Answer:
B
Step-by-step explanation:
.4 as we know can also be handled as .40, as the zero helps us determine the difference in value. 50%, though it is a percentage, can be put into decimal form. That would be .5, or again, we could add a zero to help us out, which would make it .50. As of right now, .4 is less than 50%. 3 and 13 are whole numbers, so they do not really need deep observation, except that 3 is less than 13. That would make the order of number from least to greatest .4, 50%, 3, and 13.
Answer: 137π
The usual formula for a circle centered at (a,b), with radius r,
(x - a)² + (y - b)² = r²
The area of the circle is πr², so 137π
Answer:
B, Im sorry if im wrong :(
Step-by-step explanation:
Answer:
(f o f^-1 (10)) = 10
Step-by-step explanation:
f ^ -1 = (x + 10)/10
from solving from f(x) = 10x - 10
since 10x - 10 is a one-to-one function it has an inverse
so f o f^-1 (x) = x
(f o f^-1 (10)) = 10
