W=4L/9
A=LW, using W found above gives us
A=L(4L/9)
A=4L^2/9 and we were told that A=576 so
4L^2/9=576 multiply both sides by 9
4L^2=5184 divide both sides by 4
L^2=1296 take the square root of both sides
L=36, and we know that W=4L/9 so
W=4(36/9)=16
So the dimensions are: width=16in and length=36in
Slope-intercept form of a line:
y=mx+b
m=slope
other perpendicular line to this line (y=mx+b) will have the next slope:
m´=-1/m
We have this line in slope-intercet form:
y=1/3x-7
m=1/3
A perpendicular line will have the next slope:
m´=-1/m=-1(1/3)=-3
Now, we have a point (5,-2) and the slope (-3).
point-slope form: given a point (x₀,y₀) and the slope m, the point-slope form will be:
y-y₀=m(x-x₀)
In this case:
y-(-2)=-3(x-5)
y+2=-3x+15
y=-3x+15-2
y=-3x+13
Answer: The equation of a line (slope intercept form) that is perpendicular to the line y=1/3x-7 and passes throught the point (5,-2) is:
y=-3x+13
Answer:
y = 1/25
Step-by-step explanation:
Reciprocal of y^(1/2) : 1/y^(1/2)
1/y^(1/2) = 5
y^(1/2) = 1/5
y = (1/5)^2
Answer:
Step-by-step explanation:
d
The answer to that is 0.80 which is f because you convert the answer like you would do normal equations
