Answer:
<h3>The expression for the perimeter P is
feet.</h3><h3> Area=49=lx square feet ( here
)</h3>
Step-by-step explanation:
Given that rectangle with height equals 4times width.
It can be written as
Let x be the width of the given rectangle
Therefore 
Rewritting the above equation we get
<h3>To write an expression for the perimeter P of the given rectangle :</h3>
Also given that area of the rectangle is 49 square feet.
Area=49 square feet.
We know area of rectangle = lw square units.
<h3>Therefore area=49=lx square feet ( here area=49 and w=
)</h3>
Rewritting we get
lx=49 square feet.
<h3>

(-7x + 2)^1/3 = (4 + 3x)^1/3
take the cube of both side to eliminate the 1/3 power
so you get
-7x+2=4+3x
combine like terms
-10x=2
solve for x
x=-1/5
Answer:
y=-5x+35
Step-by-step explanation:
Use the formula y = mx + b
m = slope, so plug in -5 as the slope
To find x-intercept we set y=0
We want the x-intercept to be 7 so we can plug that into the equation too
0=-5(7)+b
Answer:
x = 3
y = 1
Domain: x < 3 U x > 3
Range: y < 1 U y > 1
Step-by-step explanation:
Vertical asymptote: x = 3
Horizontal asymptote: y = 1
Domain: x < 3 U x > 3
Range: y < 1 U y > 1
The independent variable here is b, the number of mats; the dependent var. is p, the cost of b mats. Thus, p = f(b).
Here, 245 units^3 = pi*r^2*(5 units), or
245 units^3
r^2 = ------------------- = 15.61 units^2. Thus, the radius is sqrt(15.61 units^2), or
5(3.14) units 3.95 units. The DIAMETER is d = 2*r = 7.90 units.
