Answers

Step-by-step explanation:

Divide the figure into a rectangle and a triangle.

area of triangle = 0.5×5×10 = 25 square units

total area = 50+25 = 75 square units

Write the equation of
the circle with diameter
endpoints of (17,-3) and
(-13, 3).

Answers

The equation of the described circle is:

(x - 2)² + y² = 234

How to write the circle equation?

Remember that the equation for a circle whose center is (a, b) and has a radius R, is:

(x - a)² + (y - b)² = R²

Here the endpoints of the diameter are (17,-3) and (-13, 3), then the center is at:

( [17 - 13]/2, (-3 + 3)/2)

(2, 0)

And the radius is the distance between the center and any of these points:

R = √( (2 - 17)² + (0 + 3)²)

R = √234

Then the equation is:

(x - 2)² + (y - 0)² = √234²

(x - 2)² + y² = 234

Step-by-step explanation:

Perpendicular lines have negative-reciprocal slopes

The line will have a slope of:

The equation is:

y = -1/3x + b

How far will he travel if the rear wheel makes 1200 revolutions on the road? For all the years I knew my grandma, she could barely see. Grandma was legally blind, and yet she knew, by feel, the location of every dish in her kitchen and every work of literature on the bookcase in the living room. I remember especially the bird-like way she peered at things. I'd bring her a copy of my latest school picture, and she'd hold the photo an inch or two from her face, tilt her head to one side, and inspect it before saying, "Very pretty." I used to think she was just being polite, that she really couldn't see me in the picture. But then she'd add, "That pin you're wearing was your mother's." How did she see that little blur on my jacket? The things she could see never failed to amaze me. Watching television with Grandma, I never failed to learn something. Usually it was the complicated plot twist of one of her favorite soap operasThe Guiding Light or As the World Turns. We grandkids would curl up on the big couch while Grandma pulled up a footstool and planted herself right next to the TV, elbows on her knees, to watch the screen. At the commercial break, she'd explain who was marrying whom and who was in the hospital and who had recently come back from the dead. She seemed to have no trouble identifying the characters whom she could barely see. Whether or not she could bring them into sharp focus, they were as real to her as her giggling grandkids. For a treat, we'd sometimes pile into our grandparent's black car for a drive around town: my grandfather at the wheel, my long-legged older brother in the front seat, and Grandma sandwiched between me and my little brother in the backbut sitting so far forward she was practically in the front. I'd imagined all she could see was a blur of images rushing past, yet she could always tell when Grandpa had missed a turn or forgotten to turn on his headlights. Returning home, Grandma would wave at the boy who mowed their lawn and point out the new fruit on the plum tree in their yard. In later years, when I visited from college, Grand Consider a 95 percent confidence interval constructed for the difference between two populationproportions PR and Ps.
