Answer:
length = 2x = 2(9) = 18 yds
Step-by-step explanation:
Let width = x
Let length = 2x
Area = 162 yd2
length × width = Area
2x(x) = 162
2x2 = 162
Divide by 2 on both sides of equation.
x2 = 81
Square-root both sides of equation to undo the exponent.
x = √(81)
x = 9
Substitute this x value into the initial variables.
width = x = 9 yds
length = 2x = 2(9) = 18 yds
Answer: A false, B true, C true
Step-by-step explanation:
A) intercept with y axis
That means x=0
y= 3*0-2
y= -2 So A is false
B) intercept with x axis
That means y=0
0= 3x-2
2=3x
2/3= x B is true
C) The form of linear function is
f(x)= mx +n, where m is the slope
In this case m= 3 so C is true
Answer:
t=1/2
Step-by-step explanation:
No type of correlation is shown but do you have a graph
We have point
, so first calculate
. There will be:
Now, we can write the equation of the normal line as:
Normal line (and every line) crosses x-axis when y = 0, so coordinates of A:
