Answer:
D.648 inches
Step-by-step explanation:
A yard is a unit that mostly used in America and Canadia to measure the length of something field-size, so it's used a lot in sport. One yard equal to three feet, while one foot equals to 12 inches. There is a higher unit than yard called miles which equals to 1760 yards or 1.60934 kilometers.
Since the measurement is 18 yards, the length in feet will be: 18 yards * 3 feet/yard= 54 feet.
The measurement in inch will be: 54 feet * 12 inches/feet = 648 inches.
Valid because 3 x 3 is 9 :))
Answer:
Option B, (-9, -5), 3
Step-by-step explanation:
<u>The point slope form in: y - y1 = m(x - x1)</u>
m is the slope
(x1, y1) is the point
<u>Step 1: Determine what the slope and point is their equation</u>
y + 5 = 3(x + 9)
3 is the slope
(-9, -5) is the point
Answer: Option B, (-9, -5), 3
<span>A Binomial experiment has independent trails, and the outcome of a trial can be classified as either a success or a failure. Which two of the following statements also describe features of a binomial experiment?

Answer:
The graph is positive and decreasing for all real values of x where x < -1
Step-by-step explanation:
we have

The function is a vertical parabola open up
The roots (x-intercepts) are x=3 and x=-1
The vertex is the point (1,-4 ) is a minimum
using a graphing tool
see the attached figure
we know that
In the interval (-∞,-1) ---> the function is positive and decreasing
In the interval (-1,1) ---> the function is negative and decreasing
In the interval (1,3) ---> the function is negative and increasing
In the interval (3,∞) ---> the function is positive and increasing
therefore
The graph is positive and decreasing for all real values of x where x < -1
