Answer: 1.25 p , where p= Weight of Jordan's dog
Step-by-step explanation:
Let p = Weight of Jordan's dog .
Given: Emmett apostrophe's dog with 25% more than Jordan star.
Then, weight (in pounds) of Emmett apostrophe s dog = p +25% of p
= p +0.25 p [We divide a number by 100 to remove %]
= p(1+0.25)
= p(1.25)
=1.25 p
Hence, the expression represents the weight in pounds of Emmett apostrophe's dog=1.25 p
Answer:
For 4 seconds the projectile will be in the air.
Step-by-step explanation:
The function f(x) = –10(x)(x – 4) represents the approximate height of a projectile launched from the ground into the air as a function of time in seconds, x.
Now, if the projectile stays for x seconds in the air then after x seconds its height will be zero.
Hence, 0 = - 10x(x - 4)
⇒ x = 0 or x = 4
Now, x cannot be 0 as at time = 0 the projectile starts its motion.
So, for 4 seconds the projectile will be in the air. (Answer)
