You'll get -6.25
To find a negative power, put it 1 over it and remove the negative symbol. For example, to simplify 2^-4, we would do 1/2^-4, then remove the negative to get 1/2^4, which is 0.0625
Then you have that -3^3 is -27 (since -3*-3*-3 is -27). Then using the above method, you can simplify 5^-2 to 1/5^2, which is 0.4

0.0625*-27*0.4 is -27/400

2⁻⁴ * r³ * s⁻² = r³ / (s⁴ * s²) = 1 / (2 * 2 * 2 * 2) * (r * r * r) * 1 / (s * s)

2^{-4}* r^{3} *s^{-2} =  \frac{ r^{3} }{ 2^{4} * s^{2} } =  \frac{r*r*r}{2*2*2*2*s*s}

Answer:

the answer is d.

Step-by-step explanation:

D} the independent variable is cows, and the dependent variable is milk.

The independent variable is cows, and the dependent variable is milk.

The value of the independent variable, often denoted by x, does not depend on the value of another variable. The value of the dependent variable, often denoted by y, depends on the value of the independent variable.

write an equation in standard form for the line that has an undefined slope and passes through (-6,4)
Verdich [7]
Undefined slope is rise/0
run is equal to 0
that means it doesn't go left or right
means it is vertcal
means it is x=somethig

(x,y)
(-6,4)
x=-6 is the equation

oh, forgot about standard form

standard form is
ax+by=c

so

x+0y=-6 would be the equation in standard form

Radius question <br><br> * answers listed on pic but I just need a step by step explanation *
Rama09 [41]

Step-by-step explanation:

Let A(x) be the area function of given rectangle.

Radius of circle = 7x

Therefore, length of rectangle = 14x

Width of rectangle = 7x

\therefore \: A(x) =l\times w \\  =  14x   \times  {(7x)} \\ =98x^2 \\  \huge \red{ \boxed{ \therefore \: A(x) =98 {x}^{2} }}

Let P(x) be the Perimeter function of given rectangle.

P(x) =2(l + w) \\= 2(14x + 7x)\\=2\times 21x\\= 42x\\\huge \red{ \boxed{ \therefore \:P(x)= 42x}}

If the factors of function f are (x - 6) and (x - 1), what are the zeros of function f?
lidiya [134]
X=6 and x=1

You can find your zeros by determining what you have to plug into the function in order for it to equal zero

If we plug in 6, for example we’d get (6-6)(x-1)

Simplified this is 0(x-1)

Anything times 0 is 0, so this is one of our zeros.

Same goes for x-1, we just need to plug in 1 for it to equal 0

Therefore there are zeros at x=1 and x=6 :))
