The distance between ladder and bottom of the slide is 4.9 meters.

Step-by-step explanation:

Given,

Height of ladder = 1 m

Length of slide = 5 m

The ladder will serve as perpendicular and slide will serve as hypotenuse.

The distance from bottom of the slide to ladder will be base.

a = 1

c = 5

$a^2+b^2=c^2\\(1)^2+b^2=(5)^2\\1+b^2=25\\b^2=25-1\\b^2=24$

Taking square root on both sides

$\sqrt{b^2}=\sqrt{24}\\b=4.89$

Rounding to the nearest tenth

b = 4.9 meters

The distance between ladder and bottom of the slide is 4.9 meters.

Find the distance using the modulus of the difference between z1 = -8 + 3i and z2 = 7 - 4i. Show all work for full credit.

3241004551 [841]

Answer:

$\sqrt{274}$

Step-by-step explanation:

Given $z_1=-8+3i,\ z_2=7-4i.$

1. Find the difference $z_1-z_2:$

$z=z_1-z_2=-8+3i-(7-4i)=-8+3i-7+4i=(-8-7)+(3i+4i)=-15+7i.$

This complex number has real part $Rez=-15$ and imaginary part $Imz=7.$

2. The modulus of complex number z is

$|z|=\sqrt{Re^2z+Im^2z}=\sqrt{(-15)^2+7^2}=\sqrt{225+49}=\sqrt{274}.$
