Answer:

Step-by-step explanation:

1. If it is to the power of a negative, you do the reciprocal, so you know the answer will be 1/y.

2. If it is to the power of 4/3, you know it is $\sqrt[3]{y} ^{4\\}$ (y cubed to the power of 4), so the whole answer is 1/ $\sqrt[3]{y} ^{4\\}$

Which inequality is shown in the graph?

sergij07 [2.7K]

Answer:

The answer to your question is: letter C

Step-by-step explanation:

Data

Find the Parabola's equation and express the equation as an inequality.

Vertex = (0, -5)

Equation

(x- h) ² = 4p(y - k)

x² = y + 5

y = x² - 5

But, we need the area upper the parabola, then

y ≥ x² - 5

Harold measures the heights in inches of the new plants that are growing in his greenhouse He records the lengths shown below an

tensa zangetsu [6.8K]

Answer:

The least value plotted on the line plot is 18.0

The greatest value plotted on the line plot is 22.0

The height of inches occurs the most often is 19.5 with 3 times

Step-by-step explanation:

A line plot is a graph that shows frequency (the number of times the data value occurs) of data along a number line.

The line plot has dots plotted on it over each value of the number line.

Two planes are orthogonal if their normal vectors are orthogonal. Find the equation of a plane that is orthogonal to the plane 3

erica [24]

Answer:

X-5Y-4Z+12=0

Step-by-step explanation:

Plan P1 = 3x-y+2z=1. with A=(1,1,2); B=(2,2,1); we must will find V1 from P1,

V1 =(3,-1,2) and AB = (2-1,2-1,1-2) = (1,1,-1) now we find V2 by vector product.

V2 =V1.X,AB = $\left[\begin{array}{ccc}i&j&k\\3&-1&2\\1&1&-1\end{array}\right] = i+2j+3k-(2i-3j-k)=V2=(-i+5j+4k)$ ; (aplying sarrus method)

according to general plan formula a(X-Xo)+b(Y-Yo)+c(Z-Zo); V=(a,b,c)

V2=(-1,5,4) ; A=(1,1,2); so -(X-1)+5(Y-1)+4(z-2)=0 → -X+1+5Y-5+4Z-8=0 →

-X+5Y+4Z+1-5-8=0 → -X+5Y+4Z-12=0 (-1) → Plan equation X-5Y-4Z+12=0
