Answer:
the y intercept of the graph is the point where the graph crosses the y axis , y intercept are refer as vertical intercept
in this case
f(t) = -42 + 10t -25
let t = 0
y = - 42 + 10(0) - 25
y = - 42 - 25
y = -67
point of intercept
x;y
( 0 ; -67 )
Answer:
Step-by-step explanation:
The hard way to do this (no calculator) is
a = 3
n = 9
d = 2
Total = (a + a + (n-1)*d
Total = 2*3 + (9 - 1)*2
Total = 6 + 8*2
Total = 22 feet in 9 seconds.
Seems small.
= 6x + 6x - 6x × 7 + 6xy - 7y
36x2 - 42x + 6xy - 7y
Answer:
± sqrt(3)i = x
Step-by-step explanation:
0 = x^2 +3
Subtract 3 from each side
-3 =x^2 +3-3
-3 =x^2
Take the square root of each side
±sqrt(-3) = sqrt(x^2)
±sqrt(-3) = x
We can split sqrt(-3) into sqrt(3) sqrt(-1) and we know that the sqrt(-1) is i
± sqrt(3)sqrt(-1) = x
± sqrt(3)i = x
Answer:
117720 is the estimated number
