HELP PLEASE <br><br> how do i put this into a piecewise function?

Nonamiya [84]

Answer:

Step-by-step explanation:

2 functions start by making a domain

Function 1: -3≤x<1

Function 2: -1≤x≤1

Now come up with equations

Function 1= x+3

Function 2= 5

Now put it all together

f(x)= x+3 for -3≤x<1 and 5 for -1≤x≤1

Which two properties of equality could Zoe use to finish solving for x

7nadin3 [17]

3x-4= - 10
add both side 4 so its a addition property
3x=- 6
now divide both side 3 so it is a <span>division property.
so x=-2</span>

Which set of measurements can represent the lengths of a triangle's sides?

zepelin [54]

Triangle, not a triangle, not a triangle, triangle

Determining if three side lengths can make a triangle is easier than it looks. All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.[

Which is the equation of a line that has a slope of 3/2 and has the point of (-10,4)

Daniel [21]

Y = 3/2x + b
4 = 3/2(-10) + b
4 = -15 + b, b = 19
Y = 3/2x + 19

How long did it take to reach the bottom of the slope

mafiozo [28]

To solve this we are going to use the kinematic equation for final velocity: $V_{f}=V_{i}+at$
where
$V_{f}$ is the final velocity
$V_{i}$ is the initial velocity
$a$ is the acceleration
$t$ is the time

We know for our problem that the the velocity at the beginning of the slope is $2.0ms^{-1}$ , so $V_{i}=2.0$ . We also know that the speed ad the bottom of the slope is $20ms^{-1}$ , so $V_{f}=20$ . We also know that the acceleration is $6ms^{-2}$ , so $a=6$ . Lets replace those values in our formula and solve for $t$ :
$V_{f}=V_{i}+at$
$20=2+6t$
$6t=18$
$t= \frac{18}{3}$
$t=3$ seconds

We can conclude that it takes the roller coaster 3 seconds to reach the bottom of the slope.
