answer
D.-9/2, - 3, 1/2, sqrt(6), 4.2
----------------------------------
sqrt(10) is irrational number and real numbers
answer is B.irrational number and real numbers
-------------------------
square root (81) = 9
square root (100) = 10
square root (93) is between 9 and 10
so answer
9< sqrt(93) < 10
Mmm me too, and a big glass of coca cola Yummy! :)
Answer:
y maximum is at 1 for both the points (4,1) and (-4,1)
Step-by-step explanation:
The equations are,
3x + y = 8 ——— 1
4x - 2y = 3 ——— 2
Multiply equation 1 by 2
Which gives,
6x + 2y = 16 ——— 3
Now , add equation 2 and equation 3
Which gives,
10x = 19
From there , x = 19/10
Therefore x = 1.9
Now substitute x = 1.9 in the equation 1
So the equation becomes ,
3*1.9 + y = 8
From that ,
y = 8 - 5.7
Therefore , y = 2.3
So , x = 1.9 and y = 2.3.
Okay?
Answer:
- 112 ft
- 3 - 7 seconds interval
Step-by-step explanation:
<u>Given function:</u>
<u>The height of the platform is the y-intercept, when t = 0:</u>
- f(0) = - 16*0 + 96*0 + 112 = 112 ft
The ball's height is decreasing once it reaches the maximum, which is at vertex.
<u>The vertex is at x = -b/2a:</u>
<u>The ball hits the ground when f(t) = 0:</u>
- - 16t² + 96t + 112 = 0
- t² - 6t - 7 = 0
- (t - 7)(t + 1) = 0
- t = 7 (positive root)
The interval is between 3 seconds and 7 seconds
