State the Angle Relationship & Find the measure of the indicated angle that makes lines u and v parallel.
san4es73 [151]

Answer:

the indicated angle should be 121°

Step-by-step explanation:

If 2 lines are parallel to each other & a transversal intersects both of them , the corresponding angles on a same side are equal.

If the indicated angle will be equal to the given angle , they will be known as corresponding angles only when v || u.

So the indicated angle is 121°

A rectangle has dimensions 3x-1 and x+6. Write an expression for the area of the rectangle as a polynomial in standard form
WITCHER [35]

Use a graphing calculator to sketch the graph of the quadratic equation, and then state the domain and range. y=-5x^2+3x+10
Bond [772]

Answer:

The answer to your question is:

Domain: (-∞, ∞)

Range: [10, ∞)

Step-by-step explanation:

Data

Graph                                 y = 5x² + 3x + 10

Process

As it is suggested, let's use a graphing calculator. But we can sketch that because it is a quadratic equation, then the graph will be a parabola that opens upwards.

See the graph below.

Domain: are the possible values of the independent variable.

Range: are the reslunting values of the dependent variable.

Then

Domain : (- ∞, ∞)             It is an  open interval because -∞ and ∞ are

                                       not included.

Range : [10, ∞)                It is close because 10 is included.
