Weight = k/(distance)². Let's find the value of k when distance = earth radius:
180 = k/(3900)² → k = 180 x 3900² → k = 2,737,800,000
If he is at 325 miles ABOVE the earth, the distance becomes: 3,900+325=4,225 miles and his weight becomes:
Weight = k/(distance)² → Weight = 2,737,800,000/(4225)² = 153.37
Weight = 153.37 lb
(0,1)(2,7)
slope(m) = (7-1) / (2-0) = 6/2 = 3
y = mx + b
slope(m) = 3
use either of ur points...(0,1)....x = 0 and y = 1
now sub and find b, the y int
1 = 3(0) + b
1 = b
so ur equation is : y = 3x + 1....or 3x - y = -1
Answer:
(-2.5, ∞)
Step-by-step explanation:
You can add the opposite of the right side.
5.1(3 +2.2x) +14.25 +6(1.7x +4) > 0
15.3 +11.22x +14.25 + 10.2x +24 > 0 . . . eliminate parentheses
21.42x +53.55 > 0 . . . . . . . . . . . . . . . . . . collect terms
x + 2.5 > 0 . . . . . . . . . . . . . . . . . . . . . . . . .divide by the coefficient of x
x > -2.5 . . . . . . add the opposite of the constant
Answer:
The found the slope incorrectly
The found x over y instead of y over x
Step-by-step explanation:
We first need to find the slope
m = (y2-y1)/(x2-x1)
= (6-3)/(4 --2)
= 3/6
=1/2
The found the slope incorrectly
The found x over y instead of y over x
Algebra tiles would not be a good tool to use to factor the trinomial because you would need to drag an x-squared tile, 18 x-tiles, and 80 plus tiles. That is a total of 99 tiles. It would take a lot of time to drag that many tiles on the board and there might not be enough space to hold all of them. You would also need to determine how to arrange all those tiles to make a rectangle. Since 80 is a multiple of 10, you might recognize that 10 and 8 are the factors that add to 18, which would give you the values to use in the X method.
