If an archer shoots an arrow straight upward with an initial velocity of 160
HACTEHA [7]

Answer:

maximum height of the arrow will be 408 m

Step-by-step explanation:

We have given the function of height as h(t)=-16t^2+160t+8

We know that first derivative of height will be velocity

So first derivative of height

\frac{dh}{dt}=-32t+160

v(t)=-32t+160

We know that at maximum height velocity will be zero

-32t+160=0

t = 5 sec

Sp arrow will be at maximum height at t = 5 sec

So height at t = 5 sec will be

h(5)=-16\times 5^2+160\times 5+8=408m

So maximum height of the arrow will be 408 m

What is m∠1? Help me, please
vesna_86 [32]

Answer:

119

Step-by-step explanation:

By using exterior angle theorem, we know that 31+angle 1 =150. therefore angle 1=119. Exterior angle theorem is where an angle exterior of an angle in the triangle addus up to 180 degreees, we also know the angles in a triangle sum to 180 degrees. Both sides have a common angle. If we subract it from the equation, we get what is said above.

A report states that 32% of New Jersey residents think that a nice car costs too much money. Which element should probably be be
SOVA2 [1]

You should probably define what makes a car "nice", and also quantify the "too much money".


Qualitative words are often not welcomed in maths/science in general, because people can disagree on their meaning.


So, for example, if you change the sentence into


"A report states that 32% of New Jersey residents think that mercedes cars cost 30% more than they should"


Then everything would be "fixed", and there is no ambiguity anymore
