Answer:
27
Step-by-step explanation:
The rule will be
Ni=(i-1)*5+2
- i=1 → N=(1–1)*5+2=0*5+2=0+2=2
- i=2 → N=(2–1)*5+2=1*5+2=5+2=7
- i=3 → N=(3–1)*5+2=2*5+2=10+2=12
- i=4 → N=(4–1)*5+2=3*5+2=15+2=17
- i=5 → N=(5–1)*5+2=4*5+2=20+2=22
- i=6 → N=(6–1)*5+2=5*5+2=25+2=27

Answer:
Therefore the object will hit the ground after 3 seconds.
Step-by-step explanation:
Given that an object is dropped from a height of 141 feet.
Given function is
h(t)= - 16t²+141
When the object hits the ground, the height of the object will be zero.
It means h(t) = 0
Putting the h(t)=0 in the given function
0 = - 16t²+141
⇒-16t²+144=0
⇒ -16t² = -144
⇒16t²=144
Square rooting both sides
⇒t = 3
Therefore the object will hit the ground after 3 seconds.
Answer:
last year = 530570
this year = 424456
decreased plants = 530570-424456 = 106114
decreased percent = 106114÷530570×100%
= 20%
therefore 20% is the decrease precent in the number of potted plants ordered anually
Answer:
4i
Step-by-step explanation:
break up the radicand up into product of known factors 4 and 2. In this case its a negative so you put an i to indicate imaginary number because you can't rationally find the square root of a negative number
