Find answers below

Step-by-step explanation:

First know that any value raise to power zero is 1 and also according to the inverse law;

a⁻ⁿ = 1/aⁿ

Given the following

a) (-123)⁰ = 1 ()Note that any value raise to zero is 1

b) 43⁻⁵ = 1/43⁵

1/43⁵ = 1/147,008,443

c) 1/15⁻⁶ = 1/(1/15⁶)

1/(1/15⁶) = 1*15⁶/1

1/(1/15⁶) = 15⁶

d) -(1353348)⁰

= -1 (anything raise to zero is 1)

e) 13⁻⁴ = 1/13⁴

= 1/28,561

Answer:

Constraints:

$0.50y+2.25x\geq 125\\x\geq 35\\y\geq 3x$

Step-by-step explanation:

Let x represents the number of cards and y represents the number of cupcakes.

Carrie decides to sell cupcakes for $0.50 each.

Total amount earned from selling cupcakes $=0.50y$

Juanita decides to sell homemade cards for $2.25 each.

Total amount earned from selling cards $=2.25x$

As Carrie and Juanita need at least $125 to cover their start up costs,

$0.50y+2.25x\geq 125$

Juanita plans to make at least 35 cards.

$x\geq 35$

Carrie plans to sell cupcakes no less than 3 times the number of cards Juanita makes.

$y\geq 3x$

Constraints:

$0.50y+2.25x\geq 125\\x\geq 35\\y\geq 3x$

The path of a dirt bike rider follows during a jump is given by y=-0.35x^2+3x+12 where x is the horizontal distance (in feet) fr

Answer:

The highest height that can be reached is $\frac{129}{7}$ feet.

Step-by-step explanation:

The height is $y$ .

Therefore, the maximum height is the $y$ -coordinate of the vertex.

When an equation is in standard form, $y=ax^2+bx+c$ , we can use the following formula to compute the $x$ -coordinate of the vertex:

$\frac{-b}{2a}$ .

So let's compare our equation $y=ax^2+bx+c$ to $y=-0.35x^2+3x+12$ , this gives us:

$a=-0.35$

$b=3$

$c=12$ .

Let's begin the $x$ -coordinate computation of the vertex:

$\frac{-b}{2a}$

$\frac{-3}{2(-0.35)}$

$\frac{3}{2(0.35)}$

$\frac{3}{0.7}$

$\frac{30}{7}$ (Multiply by 10/10)

To find the corresponding $y$ -coordinate of the vertex given the $x$ -coordinate, we just replace $x$ in $y=-0.35x^2+3x+12$ with $\frac{30}{7}$ giving us:

$y=-0.35(\frac{30}{7})^2+3(\frac{30}{7})+12$

I will put the right hand side into my calculator:

$y=\frac{129}{7}$

The highest height that can be reached is $\frac{129}{7}$ feet.
