T=(60cos78, 60sin78)
T=(12.47, 58.69)
C=45
d=√((45-12.47)^2+58.69^2)
d≈67.1km
A. $25
The explanation would be because 365-105=206 and then double 105 which would be 210 and then subtract that from 206 which would be 50 then divide that by 2 and you would get 25
Cosine is the ratio of the adjacent side to the hypotenuse.
In short, we have this equation
cos(angle) = adjacent/hypotenuse
In the case of cos(A) = 18/19.5 we can see that
adjacent = 18
hypotenuse = 19.5
The side of 18 cm is next to angle 2, so the 18 cm side is adjacent to angle 2 (in contrast, the 7.5 cm side is the opposite leg in relation to angle 2)
So that's why the answer is angle 2
In other words, replace the '2' angle marker with 'A' to be able to write cos(A) = 18/19.5
Answer:
B)max/ opens down
Step-by-step explanation:
Parabola equation:
The equation of a parabola has the following format:
If 
, that is, x² is multiplied by a positive number, the function has a minimum value and the parabola opens up.
If 
, that is, x² is multiplied by a negative number, the function has a maximum value and the parabola opens down.
In this question:
From the graph, we already see that it opens down and has a max, and analitically, since 
, this is confirmed. The correct answer is given by option b.
Answer:
I think the answer is A.Negative
Step-by-step explanation:
From x=-5 to x=0 the slope is decreasing and from x=1 to x=6 it keeps decreasing.
