Answer:

y = 5/2

Step-by-step explanation:

-4y+6<-4 subtract 6 from both sides

-4y + 6 - 6 < -4 - 6 = -4y < -10 since both sides are negative we multiply it by -1 and get ➡ 4y < 10

Now divide both sides by 4

4y ÷ 4 < 10 ÷ 4 ➡ y < 5/2

Alexus [3.1K]

The answer is A.0.5 moles

a mole of sodium chloride weighs approximately 58 grams: 1 M - 58 g
you have 29 grams of sodium chloride, how many moles of sodium chloride do you have: xM - 29g

1 M : 58g = x : 29 g
x = 1 M : 58g * 29 g = 0.5 M

A soccer ball is kicked from the ground at an upwards velocity of 90 feet per second. The equation h(t)=-16t^(2)+90t gives the h

garri49 [273]

Answer: 2.81 s

Step-by-step explanation:

Given

Ball is kicked upward with velocity $u=90\ ft/s$

Height of the ball is given by the function $h(t)=-16t^2+90t$

Derivative of a function gives the maxima or minima at certain point

$\Rightarrow \dfrac{dh}{dt}=-32t+90\\\\\Rightarrow \dfrac{dh}{dt}=0\\\\\Rightarrow -32t+90=0\\\\\Rightarrow t=\dfrac{90}{32}\\\\\Rightarrow t=2.81\ s$

Thus, it takes ball 2.81 s to reach the top.
