The equation is <span>h(t) = -16t2 + 1600</span>.
When the package hits the ground, h(t) = 0: 0 = -16t2 + 1600 To solve by factoring: 0 = -16(t2-100)0 = -16(t+10)(t-10) t = -10 and +10 seconds.
Since we aren't interested in negative time, t = 10 seconds.
2) 2/7 divided 1/3 = 6/7
3) 4/9 times 3/8 = 1/6
4) 5/8 times 2/15 = 1/12
5) 1 divided 3/4 = 1 1/3
6) 1/8 times 8 =1/64
7) 2 1/4 times 1/6 = 3/8
8) 5/8 times 2 2/3 = 1 2/3
9) 1 1/8 times 4 = 4 1/2
10) 2 1/5 divided 11 = 1/5
11) 4 1/2 times 1 1/3 =6
12) 2 1/7 divided 3 3/7
13) 2 2/9 times 7 = 16
The equation for the sum of interior angles is :
Sum = (n-2) x 180, where n is the number of sides.
Replace sum with the given sum:
3960 = (n-2) x 180
Divide both sides by 180:
22 = n-2
Add 2 to each side:
24 = n
It has 24 sides.
For Each interior angle, divide the total sum by the number of sides:
3960 / 24 = 165 degrees
The interior and exterior angle needs to equal 180 degrees. To find the exterior angle, subtract the interior angle from 180:
180 - 165 = 15 degrees.
So we look at the conditions
if x<1 and if x≥1
x<1 means x is less than 1
x≥1 means x is greater than 1 including 1
that includes all real numbers
so domain is all real numbers
range is (sart with top and go up, if x=1 then f(1)=7 so from 7 to infinity, then other one, x<1, -inifinity to 4 not including 4
so the range with interval notation is (-∞,4) U [7,∞)
graph is the graph of each, but pt together (see attachmetn)
