Jack and Jill start driving from the same location. Jack drives 30 miles south while Jill drives west. If Jack and Jill are 78 m
arsen [322]

Answer:

72 mles

Step-by-step explanation:

For better understanding, I'll make use of an attachment.

From the attachment,

O represents the start point

OB = 30 --- Jack

AB = 78 -- Distance between them

Required

Find OA; Jack's distance

To do this, we make use of Pythagoras theorem

AB^2 = OA^2 + OB^2

This gives:

78^2 = OA^2 + 30^2

6084 = OA^2 + 900

Subtract 900 from both sides

OA^2=  6084 - 900

OA^2=  5184

Take square roots

OA = \sqrt{5184}

OA = 72

<em>Hence, Jill drove 72 miles</em>

If c-d=7 and c=3-8i what is d<br> a) -4+8i<br> b)-4-8i<br> c)4+8i<br> d)4-8i
Zigmanuir [339]

Answer:

Step-by-step explanation:

c - d = 7

c = 3 - 8i            Substitute into the top equation

3 - 8i - d = 7      Subtract 3 from both sides

- 8i - d = 7 - 3    Combine

-8i - d =4            Add 8i to both sides

-d = 4 + 8i           Multiply through by -1

-1*-d = -4 - 8i

d = - 4 - 8i

Looks like B is the answer.
