Y = <span>b^x
when x = 1
y = b^1
y = b
Therefore, the value of b is the same as the value of y when x =1
From the graph,
When x = 1, y = 0.5
Therefore, b = 0.5
To confirm this
From the graph,
When x = -1, y = 2
Since </span>y = b^x<span>
2 = </span>b^-1
2 = 1/b
2b = 1
b = 0.5
When x = -2, y = 4
Since y = b^x
4 = b^-2
4 = 1/(b^2)
b^2 = 1/4
b = √(1/4)
b = 1/2
b = 0.5
Therefore, it is conformed that b = 0.5
1. Divide 95 million by the amount of days in a year
95 million divided by 365 = $260273.97
$260273.97 is made in a day.
Multiply it by 9.
So, 260273.97 x 9 = $2342465.75
$2342465.75 is made in 9 days.
Answer:
x = - 3.42443 or 6.42443
Step-by-step explanation:
Answer:
slope= 11
Step-by-step explanation:
(12,23) = (x1,y1)
(14,45) = (x2,y2)
Now,
slope(m)= (y2-y1)/(x2-x1)
=(45-23)/(14-12)
=22/2
=11
Subtract 7.8 points by 4.8 and you get 3.4 !!
