Step-by-step explanation:
5√x+3 = -20
÷5. : √x+3 = -4
square: x+3 = 16
-3: x = 13
√x+18 -2 = x -4
+2 : √x+18 = x -2
square: x+18 = x^2 - 4x +4
-18: x = x^2 -4x -14
-x : 0 = x^2 -5x - 14
foil: (x- 7) (x+2) = 0
x = 7, -2
You need to <span>draw the diagram to understand the problem easily. Teh diagram will show the right triangle, acute angle with the base 7º, height is 663 m, and "x" is the base of the triangle.
using the tangent ratio:
tan</span>Θ = opposite / adjacent
<span>
tan7º = 663 m / x
x = 663 m / tan7º
x = 5,399.7 m
change m to km. 1,000 m = 1km
5,399.7m * 1km/1,000 m = 5,399.7 km/1000 = 5.3997 km or 5.4 km
B. 5.4 km </span>
Answer:
well when you hear "union" you think 'joined' or 'together' since thats what it means, In a mathmatical set of numbers, union means that both of the sets are necessary for the equation to be true. I'm not sure what the sets are in this problem but in order to get "union" from anything, that means that when you checked for your domains, the values that you got had to be part of both the given sets
Answer:
The coordinates are:
A ( 4,7 )
B ( 8,10 )
c ( 7,7 )
Step-by-step explanation:
You could take the original coordinates and add the x value with 3 and y value with 6. Like for example...
The original coordinates of C is ( 4,1 ). Hence you could add the x value with 3 and y value with 6. 4 + 3 and 1 + 6 giving you the coordinates after translation = ( 7,7 )
Answer:
-0.777777...
Divide -9 by 10. It will be -0.111111... But it's <em>7</em>/9. So we multiply -0.111... by 7 which is -0.777...
So, the answer is -0.777...
(And don't write the ... It's just representing that it's repeating.)
