Answer:

±10 i

Step-by-step explanation:

sqrt(-100)

We know that sqrt(ab) = sqrt(a) sqrt(b)

sqrt(-1) * sqrt(100)

sqrt(-1) = i

i * ±10

A right triangle has one leg that is 12 units long and a hypotenuse that is 15 units long. Find the length of the other leg.
viva [34]

Answer:

9

Step-by-step explanation:

let's assume ;

12=a

15=c

?=b

so;

a2+b2=c2

(12)2+b2=(15)2

144+b2=225

b2=225-144

b2=81 (square root both sides)

You'll get

b=9

NB; 2 is used as squared

On a piece of paper, graph y&gt;x-1. Then determine which answer choice
zepelin [54]

The graph that matches the given equation is y≥x-1 is Graph A.

Option: C.

<u>Step-by-step explanation:</u>

The given equation y≥x-1 is a linear inequality equation.

Graphing Linear Inequalities differs from graphing regular linear equations. That is it has certain rules to be followed to draw the graph.

  1. First, rearrange the equation as y in the left and other terms in the opposite side.
  2. Check for the line: y= , y≤ and y≥ comes with straight line where as y< and y> comes with a dotted line.
  3. Shading: If y> greater than or y≥ greater than or equal is present then the space above the line has to be shaded. If y< less than or y≤ less than or equal  is present then the space below the line has to be shaded.

For the given equation y≥x-1,

The line will be solid passing through (0,-1) and (3,2) since it has y≥. Also, the region above the line is shaded.

So the graph A is the graph that matches the equation y≥x-1.
