Answer: The last option.
Step-by-step explanation:
1. By definiton, the rotation rule 90° about the origin is:
(x,y)⇒(-y,x)
2. You know that the coordinates of triangle X'Y'Z' are the following:
X'(-2,2)
Y'(0,6)
Z'(1,1)
3. Now, when you apply the rule, you obtain that the coordianates of the pre-image are the following:
X(2,2)
Y(6,0)
Z(1,-1)
Therefore, the answer is the last option.
Answer:
19 meters
Step-by-step explanation:
if he goes straight up at 90 degreed to the surface of water, it would be 19 metres
Answer:
it does not
this is because his income increases at a constant rate. At any given week, his income increases by double
Step-by-step explanation:
An exponential function is usually in the form :
where a = positive constant other than 1
x = variable component
for example ,
Assume that Jordan saves $15. he increases this amount by 10% weekly. this statement represents an exponential function.
The amount he would have in 7 weeks = 15 x (1.1)^7 = 29.23
Answer:
In the case of a decimal number, we round down to find the actual number of guesses. Therefore, for a 1000-element array, binary search would require at most 10 guesses. (which is 2,097,152), so we would need at most 22 guesses.
