Answer:
it will be equal to
okay....
Step-by-step explanation:
volume of a cuboid = l × b × h
( where l = length, b = width , h = height )
so volume of given cuboid = ( 3x × 2x × 2x )
hence volume =
Answer:
y = 2x +1
Step-by-step explanation:
y=kx+1
Substitute the point into the equation
3 = k(1) + 1
3 = k+1
Subtract 1 from each side
3-1 = k
2 = k
y = 2x +1
The slope is 2 and the y intercept is 1
Answer: 48
first you do 2x3 then divided by 2 to get one of the small triangles which is 6/3= 2 then double that to get the other small triangle so you have 2+2=4
then you find the area of the rectangle which you do 8+3 to get the whole of the length so it’s then 11x4= 44
then add the 4 from the two triangles and you get the area as 48
i think this is right
4:30 because when you add the minutes then subtract the sum from ^:00 that is answer you get
Answer:
y = (-1/19)(x - 8)² + 1521/76
Step-by-step explanation:
A parabola moves in such a way that it's distance from it's focus and directrix are always equal.
Now, we are given that directrix is y = 9.75 and focus is at (8, 0.25). Focus can be rewritten as (8, ¼) and directrix can be rewritten as y = 39/4
If we consider a point with the coordinates (x, y), it means the distance from this point to the focus is;
√((x - 8)² + (y - ¼)²)
Distance from that point to the directrix is; (y - 39/4)
Thus;
√((x - 8)² + (y - ¼)²) = (y - 39/4)
Taking the square of both sides gives;
((x - 8)² + (y - ¼)²) = (y - 39/4)²
(x - 8)² + y² - ½y + 1/16 = y² - (39/2)y + (39/4)²
Simplifying this gives;
(x - 8)² - (39/4)² = (½ - 39/2)y
(x - 8)² - 1521/4 = -19y
(x - 8)² - 1521/4 = -19y
Divide both sides by -19 to get;
y = (-1/19)(x - 8)² + 1521/76
