Answer:
B: 378 cm^2
Step-by-step explanation:
22 * 24 = 528
528 - (10 * 15) = 378
Answer:
1 and 3 are both perpendicular to segment NY
Step-by-step explanation:
1. Find the slope of line NY
slope of NY = 5-(-7)/-11-5 = - 3/4
Any line that is perpendicular to NY should have a slope of the inverse of negative slope of NY.
2.Find the slope of perpendicular lines
the inverse of negative slope of NY = - (-4/3) = 4/3
You have not given enough information for us to complete the full equation for a circle but we can get close.
The equation of a circle is: (x - h)² + (y - k)² = radius²
where the center is represented by (h , k). I shorted the word 'radius' to variable r.
You would just plug in your given information and simplify:
(x - (- 1))² + (y - 0)² = r²
Your answer would be:
(x + 1)² + y² = r²
You did not provide a radius or another point on the circle so we could find the radius so you are left with this incomplete equation of a circle.
Answer:
For the diagonal of the floor:
20^2 + 48^2= c^2
400+2304= c^2
c=52
For the diagonal of the cube:
52^2 + 10^2 = c^2
2704+100=c^2
c=52.95
Rounded= 53
