Answer:
≈ (3.578, 5.789)
Step-by-step explanation:
We can substitute for y and solve for x.
(x -h)^2 +(y -k)^2 = r^2 . . . equation of a circle with center (h, k), radius r
x^2 +(y -4)^2 = 4^2 . . . . . . the equation of the given circle
x^2 +((0.5x +4) -4)^2 = 16
(5/4)x^2 = 16
x = 8/5√5 . . . . multiply by 4/5 and take the square root
y = 0.5x +4
y = 4/5√5 +4
The point of intersection is (8/5√5, 4+4/5√5), approximately (3.578, 5.789).
How what size is the large block?
Convert the measurements of the large block to cm.
Then calculate the Volume of the large cube.
The answer will be in cubic cm. That is the number of 1 cm cubes.
Answer:
width = 6 and length = 8
Step-by-step explanation:
perimeter = 2*(length + width). (1)
and we have that length = 2 + width
in (1)
28 = 2 *(width + 2 + width)
14= 2*width +2
width =6
and so length will be 8
Answer: this is the awnser
