If they have the same charge
x+x+x+x+x+x+x=-42
7x=-42
x=-6
so to check our answer
-6-6-6-6-6-6-6=-42
-12-12-12-6=-42
-24-18=-42
-42=-42
Answer:
47
Step-by-step explanation:
the formula is πr²h/3= pi=22/7, so 22/7x 3x 5/3= 47.12389 simplified= 47
Answer:
y=5x-2
Step-by-step explanation:
5*-2=-10 -10-2=-12
5*-1=-5 -5-2=-7
5*0=0 0-2=-2
5*1=5 5-2=3
5*2=10 10-2=8
Answer:
1/2
Step-by-step explanation:
The slope is given by
m = (y2-y1)/(x2-x1)
= (6 - -1)/(12 - -2)
= (6+1)/(12+2)
7/14
1/2
Answer:
Part A) 
Part B) 
Part C) 
Step-by-step explanation:
Part A) we know that
In the right triangle ABC of the figure the sine of angle A is equal to divide the opposite side angle A by the hypotenuse
so

substitute the values

Part B) we know that
In the right triangle ABC of the figure the cosine of angle A is equal to divide the adjacent side angle A by the hypotenuse
so

substitute the values

Part C) we know that
In the right triangle ABC of the figure the tangent of angle A is equal to divide the opposite side angle A by the adjacent side angle A
so

substitute the values
