Answer:

=1.283 , 0.779 seconds

Step-by-step explanation:

h=2+33t-16t²

when h=18 ft

then18=2+33t-16t²

→ 16t²−33t+16=0  

t= [−(−33)±√{(−33) ²−4×16×16)}]/(2×16)

= [33±√{1089−1024}]/(32)

= [33±√{65}]/(32)

=1.283 , 0.779 seconds

1-4y^2 = 0<br> Solve the equation
Romashka [77]

Answer: y = 1/2 or y = -1/2

Step-by-step explanation:

First move the 1 to the side with the 0

-4y^2 = -1 // -1 because when you move a number to the other side of the equation  you have to multiply -1

Then divide by -4 on each side

y^2 = 1/4

square root each side

|y| = 1/2 // sq rt y^2 becomes an absolute value because when you square root a square it automatically becomes an absolute value

so the answer would be y = 1/2 or -1/2

to check just put it into the equation as y. Both work.

Find the value of x?
Burka [1]

Answer:

<em>We </em><em>know </em><em>that </em><em>the </em><em>exterior </em><em>angle </em><em>of </em><em>a </em><em>triangle </em><em>is </em><em>equal </em><em>to </em><em>the </em><em>sum </em><em>of </em><em>two </em><em>opposite</em><em> </em><em>interior </em><em>angle. </em>

Step-by-step explanation:

So

25x + 57 + x = 45x

26x + 57 = 45x

57 = 45x - 26x

19x = 57

Therefore x = 3

Hope it will help you
