(x^2+1)(x+2)(x −2)
*ps the ^ means it’s a exponent
Hope I helped <3 sorry if I was wrong :(
Use a variable to represent the number of hours the technician will work, plus the $50.
50+25x
This would be the expression used to find the amount of money the technician needs.
The correct answer is: Proust Was a Neuroscientist<span> by Jonah Lehrer
Science ordinarily applies a reductionist approach. To structure a testable theory that could Additionally make faultlessly retested, simulated constructs would made. This is carried will permit clean analyses Also information about statistically huge correctness. However, the test will be we should constantly make what we’ve discovered et cetera check whether it fits Previously, with the bigger picture of how things worth of effort. Our particular social order regularly imitates this reductionist approach Concerning illustration it may be progressively disjointed, with accentuation on the need will practice. As a rule A large portion researchers don't completely appreciate, understand, alternately worth the human experience Also practically specialists don't completely appreciate, understand, alternately quality those rigors of the experimental technique. [I will concede on this continuum, i might fit additional under the experimental outlook battling on like craftsmanship. ] what i might have been laid open should for perusing Proust might have been An neuroscientist is how frequently all the Workmanship predated science. With watchful investigation under those reality of the human experience there may be extraordinary knowledge under mankind's nature, our senses, and the route our universe meets expectations. Mind blowing specialists intuited the thing that the researchers of the day didn't have confidence alternately Might not yet substantiate. With occasion when science need made up for lost time with the thing that symbolization recently knew, Be that i wonder how regularly this transaction of the two planets might have been acknowledged what's more entryway much speedier we Might have gotten here whether science seen art.

Let h(t) represent the height of the projectile after t seconds. If the projectile is being launched from the ground, then h(0)=0, and h(t)=-4.9t²+98t. When the equation is in this form, the maximum height is determined by -98/2(-4.9), or after 10 seconds. Thus
-4.9(100)+98(10)=490 m as the highest point of the projectile
Then, when it hits the ground, h(t)=0, so
0=-4.9t²+98t
98t=4.9t²
4.9t=98
t=20
