While performing a vertical line test on a graph, you notice that the graph intercepts the vertical line twice. Which of the fol

pav-90 [236]

Answer:

The correct statement is:

Because the vertical line intercepted the graph more than once, the graph is of a relation, but it is not a function. ⇒ C

Step-by-step explanation:

We use the vertical line test on a graph to show the graph represents a function or a relation

If the graph and the vertical line intersected at an only ONE point then the graph represents a function

If the graph and the vertical line intersected at more than one point, then the graph does not represent a function it represents a relation

Let us use these facts to answer the question

∵ While performing a vertical line test on a graph, you notice that

the graph intercepts the vertical line twice

→ That means the line intersected the graph at more than 1 point

∴ The graph does not represent a function it represents a relation

The correct statement is:

Because the vertical line intercepted the graph more than once, the graph is of a relation, but it is not a function.

Which of the following algebraic expressions is not simplified?

Hunter-Best [27]

Answer:

B. $x+2x$

Step-by-step explanation:

we will verify each options

option-A:

we have

$x+1$

we can see that x and 1 are different terms

so, they are not like terms

so, we can not combine or simplify it

so, this is in simplest form

this is FALSE

option-B:

we have

$x+2x$

we can see that 2x and x are same type of terms

so, they are like terms

so, we can combine or simplify it

$x+2x=3x$

So, this expression is not in simplest form

this is TRUE

option-C:

we have

$x^2+x$

we can see that x^2 and x are different terms

so, they are not like terms

so, we can not combine or simplify it

so, this is in simplest form

this is FALSE

option-D:

we have

$5x^3-x$

we can see that 5x^3 and x are different terms

so, they are not like terms

so, we can not combine or simplify it

so, this is in simplest form

this is FALSE

How far must the outfielder throw the ball to return it to the pitcher? Round to the nearest foot. 112 feet 125 feet 145 feet 15

shusha [124]

The distance the outfielder must throw the ball to return it to the pitcher is 125 feet.

Given

On a softball field, the home plate is 43 feet from the pitcher’s mound.

A ball is hit at an angle of 27° east of the pitcher’s mound.

The ball travels 162 feet before it is caught by an outfielder.

<h3>How to use the cosine rule to find the distance?</h3>

Distance of the home plate from the pitcher's mound = 43 feet

The angle at which the ball is hit = 27° east of the pitcher's mound

The distance the ball travels before it is caught = 162 feet

The sides, b and c, and the included angle, A, of the triangle drawn are respectively;

b = 43 feet

c = 162 feet

A = 27°

The length of the third side, of the triangle, is the distance from the outfielder to the pitcher.

According to the law of cosines, we have;

a² = b² + c² - 2·b·c·cos(A)

a² = 43² + 162² - 2 × 43 × 162 × cos(27°) ≈ 15679.497105

Approximating to the nearest foot, we get;

a = 125 feet

Hence, the distance the outfielder must throw the ball to return it to the pitcher is 125 feet.
