91 is 70 percent of the price
70% of 130 is 130*0.7 = 91
Answer:
4 seconds.
Step-by-step explanation:
The function f(x)=-10(x)(x-4) ........ (1), represents the approximate height of a projectile launch on the ground into the air as a function of time in seconds x.
Now, we are asked that for how long from the launch does the projectile stays in the air.
Therefore, we have to solve the equation (1) making f(x) as zero.
Hence, 10x(x - 4) = 0
⇒ x = 0 or x = 4
(As x can not be zero since at x = 0 sec, the projectile was at the ground.}
Hence, x = 4 seconds.
Therefore, the projectile was in the air for 4 seconds. (Answer)
Answer: Option A. |-7| = 7
Solution:
The distance is a positive value, then we must not take in account the sign, and using:
|a| =-a if a<0
with a=-7
|-7| = -(-7)
|-7| = 7
Answer:
x = undefined
Step-by-step explanation:
Because you have an x and then remove the x the it is not pssible to tell what x was with the given information causing it to be undefined.
