You have to use SohCahToa to figure out the length of AB
Answer:
Option B. y = 2x; 20 feet
Step-by-step explanation:
1. Determination of the equation that represents the relationship.
Let y be the distance travelled.
Let x be the time taken.
Let K be the speed.
From the question given above, the following data were obtained:
Distance (y) = 80 ft
Time (x) = 40 s
Speed (k) =.?
Speed = Distance /time
K = y/x ......... (1)
K = 80/40
K = 2 ft/s
Substitute the value of k into equation 1
K = y/x
K = 2 ft/s
2 = y/x
Cross multiply
y = 2x
Therefore, the equation that represents the relationship is y = 2x
2. Determination of the distance travelled in 10 s.
Speed (k) = 2 ft/s
Time (x) = 10 s
Distance (y) =.?
y = 2x
y = 2 × 10
y = 20 ft
Therefore, the person will travel 20 feet in 10 seconds.
From the above calculations, the right answer to the question is
Option B. y = 2x; 20 feet
Answer:
Step 2
Step-by-step explanation:
The quadratic formula is given by 
Our equation is y = 2x²-x-6
So here our a = 2, b = -1, and c = -6
We can now plug these numbers into our formula
Step 2 is incorrect because it states that "x equals the negative of negative 1 plus or minus the square root of negative one plus forty-eight all over two times 2."
The correct statement would be "x equals the negative of negative 1 plus or minus the square root of positive one plus forty-eight all over two times 2.", because the square of a negative is positive, resulting in a positive one.
Since this step is incorrect, the steps after are also incorrect, but Harry went wrong at Step 2
Answer:
C. II only
Step-by-step explanation:
Basically all you need do is plug these answers in and if the complete the inequality to make a true statement.
Yes i know no body want to do that but that whats need to be done lol.
once i plug 7 12/7+8 = 12.83
12.83>20
is incorrect
so we need continue
7*2.5+8>20
7*2.5= 17.5
17.5+8= 25.5
25.5>20
this a true statement
so we know 2.5 is an answer
now we need plug in -3
7*-3= -21
-21 +8 = -13
-13>20
this is incorrect
