Answer: =34
=3⋅3⋅3⋅3
=81
For example, 3 to the power of -4:
=3−4
=134
=13⋅3⋅3⋅3
=181
=0.012346
Step-by-step explanation: the solution is expanded when the base x and exponent n are small enough to fit on the screen. Generally, this feature is available when base x is a positive or negative single digit integer raised to the power of a positive or negative single digit integer. Also, when base x is a positive or negative two digit integer raised to the power of a positive or
negative single digit integer less than 7 and greater than -7.
hopefully this is right :/
If you use this equation then you say that the ground is h=0 and solve as a quadratic.
The quadratic formula is (-b±<span>√(b^2-4ac))/2a when an equation is in the form ax^2 + bx + c
So the equation you have been given would be -16t^2-15t-151 = 0
This equation has no real roots which leads me to believe it is incorrect.
This is probably where your difficulty is coming from, it's a mistake.
The equation is formed from S=ut+(1/2)at^2+(So) where (So) is the initial height and S is the height that you want to find.
In this case you want S = 0.
If the initial height is +151 and the initial velocity and acceleration are downwards (negative) and the initial velocity (u) is -15 and the initial acceleration is -32 then you get the equation S=-15t-16t^2+151
Solving this using the quadratic formula gives you t = 2.64 or t = -3.58
Obviously -3.58s can't be the answer so you're left with 2.64 seconds.
Hope this makes sense.

Answer:
9 cups of flour
Step-by-step explanation:
Multiply by 3. 8 cups of water multiplied by 3 is 24 cups of water so you do the same to the flour to keep them balanced and ratioed. So 3 cups of flour times 3 is 9 cups of flour. 8:3 is the ratio.
