d
a
Step-by-step explanation:
f(3)= 3(3)-1
f(3)=9-1=8
f(x+1)= (x+1)^2-3(x+1)+2
=x^2+2x+1-3x-3+2
=x^2-x
It's called perfect cubes
Answer:
P = 30 degrees, PQ = 6.93, PN = 8
Step-by-step explanation:
For the angle, just subtract the angles you already know from 180, so 180 - 90 - 60= P. P = 30 degrees.
For PQ, use tan60 = x/4, or 4tan(60), which equals 6.93.
For PN, use cos60 = 4/x, or 4/cos60, which equals 8.
Hopefully this helps- let me know if you have any questions!
proportional relationship in our everyday life: When we put gas in our car, there is a relationship between the number of gallons of fuel that we put in the tank and the amount of money we will have to pay. In other words, the more gas we put in, the more money we'll pay.
1/2=3/6
3/6+1/6=4/6 goodluck
