Answer:
18
Step-by-step explanation:
30*0.4=12
This means 40% of 30 is 12 and Ana has completed 12 problems.
30-12 = 18, so she still needs to do 18 problems.
Replace x in the given equation with each value:
a. f(4) = 2(4) -5
= 8-5
=3
b. (f-3) = 2(-3) - 5
= -6 -5
= -11
Yep exponential functions are shown in the answer 2
The ratio the point P partition the directed line segment from M to N is 9:2
<u>Step-by-step explanation:</u>
Let the total distance between M and N be 'd'
Point P distance from M = (9/11) d
Point P distance from N = (1 - 9/11) d
= (2/11) d
The ratio of the distance = (9/11) d / (2/11) d
= 9/2
= 9:2
The ratio the point P partition the directed line segment from M to N is 9:2
