Answer:
Use the formula for the distance between two points: d = √((x2 – x1)2 + (y2 – y12))
Step-by-step explanation:
d = √((5 – 0)2 + (2 – 0)2
d = √(25 + 4) = √(29) ≈ 5.385
Answer:
Step-by-step explanation:
The inner product is the sum of products of corresponding components:
(7,2) • (0,2) = 7·0 +2·2 = 4

For example, one group may have been exposed to a particular substance that the other was not. Also called retrospective study.
Step-by-step explanation:
"For an exponential function in the form of y=ab^x, if b is between 0 and 1, what happens to the graph of the function as x increases is that <span>The graph curves down away from the x-axis.

Answer:
The last answer choice is correct, I am pretty sure.
Just go on the calculator (like Desmos) and just use the decimals to determine which one is true.
