7(4x+4)+5x, 28x+28+5x, 33x+28. Answer: A.
Answer:
the side lengths will be 4√2- 4√2 - 8
Step-by-step explanation:
When you have missing side lengths of a right triangle, you can use special triangles to find the side lengths. Where the angles are 45-45-90, each triangle has side lengths with the relationship 1 - 1 -√2.
This means for problem 9, the side length 8 is the equivalent of the special triangle √2 * √32 = √64 = 8. So each side is multiplied by √32.
So the side lengths will be 4√2- 4√2 - 8.
These are found using:
1*√32 = √32 = 4√2
1*√32 = √32=4√2
√2*√32 = √64 = 8
Perimeter = 2L + 2W
since it’s a square, all sides are equal so
perimeter = 4s
s = 13
so multiply 13 by 4
perimeter = 13*4 = 52
Answer:
8192
Step-by-step explanation:
The pattern is mulitply by 2 to get the next term
4*2=8
8*2=16
So: 4,8,16,32,64,128,256,512,1024,2048,4096,8192
Answer:
(8) d. 4/3 (9) a. (X - 4)^2 + (y-4)^2= 25
Step-by-step explanation:
8. CENTER OF CIRCLE: O (2,6)
radius of circle : r = √4 = 2
if m = 4/3 line: y = 4/3 x
perpendicular distance (d) from center of circle to line y = 4/3 x is
d = |((4/3 x 2) + (-1) x 6)| / √((4/3)² + (-1)²) = |(-10/3)| / √(25/9) = (10/3) / (5/3) = 2
d = r means line touch with circle
9. center of circle is the intersection of the diagonals of rectangle (4,4) and its radius is 5 (illustrated)
the equation of circle: (X - 4)^2 + (y-4)^2= 25
