ANSWER:
A. y= -4x - 4
EXPLANATION:
y2-y1
——— This is used to find the slope
x2-x1
4-(-4)=8
0-2=-2
8/-2=-4
So the slope should be -4.
Since the y-intercept is shown in (0,4), the y-intercept is 4.
Answer:
Step-by-step explanation:
Alright, lets get started.
Using sin Law,

Plugging the value of a, b and angle A




taking sin inverse on both sides

The may be another value of B that will called B' = 
We will not consider this B' value because the um of angle B' and A will exceeds 180 degree (
)
Thats why only one triangle is possible. : Answer
Hope it will help :)
The equation of the height as a function of time for this case is given by:
h (t) = - 16t ^ 2 + 10t + 100
By the time the egg hits the ground we have:
-16t ^ 2 + 10t + 100 = 0
We look for the roots of the polynomial:
t1 = -2.2069555463432966
t2 = 2.8319555463432966
As it is about time, we use the positive root:
t = 2.83 s
Answer:
it hits the ground at:
t = 2.83 s
Answer:
Step-by-step explanation:
breadth = x
length = 2x
Perimeter = 540m
2*( length + breadth ) = 540
2 *(2x + x) = 540
3x = 540/2
3x = 270
x = 270/3
x = 90 m
Breadth = 90m = 90 *100 = 9000 cm
Length = 2*90 = 180 m = 180 * 100 = 18000 cm
No.of bricks = Area of room/ area of one brick
= 9000 * 18000 / 20 * 12
= 675000 bricks
Answer:
None, unless c was a typo
Step-by-step explanation:
Distributing gets us xy+2x=5
None of the options is that
If you meant option c as xy+2x = 5 though, then it would be correct
