The answer is A because we simplify the 7 b by subtracting 6 b which gives us 1 b but in this case it will just be B and then we add 7c
Hello,
a) k=8+6=14 cm

so after 1 week Alfred is faster on 3 words
so after 4 weeks he could type 35 words per minute
Answer: C
Step-by-step explanation:
The thirty choices goes in the front because that’s the total number
For this case we have an equation of the form:
h (t) = (1/2) at2 + vot + h0
Where:
a: acceleration
vo: initial speed.
h0: initial height
Substituting values we have:
h (t) = - 16t2 + 19t + 110
The initial speed is then:
vo = 19 feet / s
Answer:
The initial velocity when the rock is thrown is:
vo = 19 feet / s
