Answer:

D, the horizontal line is a function

Step-by-step explanation:

To pass the vertical line test, a vertical line cannot go through the function more than once

A is a vertical line so it will fail the vertical line test

B will fail the vertical line test at many points. One example is at

x =0 where you can see it will intersect at two points

C will fail the vertical line test at many points. One example is at

x =0 where you can see it will intersect at two points

D is a horizontal line. This will pass the vertical line test

Write the if/else statement as the conditional expression that performs the same option result = x < y ? x * 5 : a b;

Semenov [28]

The conditional statement is

if x < y:

result = x * 5

<h3>How to write the if/else statement as the conditional expression that performs the same option?</h3>

The statement is given as:

result = x < y ? x * 5

The above means that,

the variable result is assigned x * 5 if x < y

So, the conditional statement is

if x < y:

result = x * 5

A rectangle has a length that is 9 feet less than four times its width. Its area is 90 square feet

kramer

Answer:

The length of rectangle is $15\ ft$

The width of rectangle is $6\ ft$

Step-by-step explanation:

Let

x-----> the length of rectangle

y----> the width of rectangle

we know that

The area of rectangle is equal to

$A=xy$

$A=90\ ft^{2}$

$90=xy$ -----> equation A

$x=4y-9$ -----> equation B

substitute equation B in equation A and solve for y

$90=(4y-9)y$

$4y^{2}-9y-90=0$

using a graphing calculator

The solution is

$y=6\ ft$

Find the value of x

$x=4y-9$ -----> $x=4(6)-9=15\ ft$

36, ___, ___, 32/3 is a geometric sequence, with some terms missing. First, please solve for "r", the common ratio between each

Ksju [112]

Answer: r = 2/3

Step-by-step explanation:

In a geometric sequence, the consecutive terms differ by a common ratio. The formula for determining the nth term of a geometric progression is expressed as

Tn = ar^(n - 1)

Where

a represents the first term of the sequence.

r represents the common ratio.

n represents the number of terms.

From the information given,

a = 36

The 4th term is 32/3

n = 4

Therefore,

T4 = 32/3 = 36 × r^(4 - 1)

32/3 = 36 × r^3

Dividing both sides if the equation by 36, it becomes

32/3 × 1/36 = r^3

8/27 = r^3

Taking cube root of both sides of the equation, it becomes

(8/27)^1/3 = r^3 × 1/3

r = 2/3
