Answer:

d=\sqrt{2,537}\ m   or  d=50.37\ m

Step-by-step explanation:

we know that

the formula to calculate the distance between two points in three dimensions is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}+(z2-z1)^{2}}

Let

A(5,3,1)  -----> coordinates of the barrel of her gun

B(38,41,3)  -----> coordinates of the target

substitute the values

d=\sqrt{(41-3)^{2}+(38-5)^{2}+(3-1)^{2}}

d=\sqrt{(38)^{2}+(33)^{2}+(2)^{2}}

d=\sqrt{1,444+1,089+4}

d=\sqrt{2,537}\ m

d=50.37\ m

2(4x - 1) + 3(3 - 2x) = 0
LUCKY_DIMON [66]
2(4x-1) + 3(3-2x)=0
distribute
8x-2+9-6x=0
add like terms
2x+7=0
subtract 7 from both sides
2x= -7
divide both sides by 2
x=-7/2
