combine like terms4ln(x) = 8

divide both sides by 4.ln(x) = 2

exponentiate both sides.eln(x) = e^2

inverse property of exponents and logs x = e^2

Which equation can be used to find the surface area of the cylinder

Phoenix [80]

2πr^2 + 2πrh.
r is the radius circle face.
h is the length/height of the cylinder.
πr^2 is the formula for circles, and there are 2 circles in a cylinder. So 2 x πr^2 would be determine the area of the 2 circles.
2πr is the formula for circumference. 2πr x h would the area of the curved face.

Let x1 = 12, y1 = 15, and y2 = 3. Let y vary inversely with x. Find x2.

Ostrovityanka [42]

We have that an inverse variation in a function is given by:
$y = k / x
$
We must find the value of the constant k.
To do this, we substitute the values of x1 = 12, y1 = 15.
We have then:
$15 = k / 12
$
Clearing k we have:
$k = (15) * (12)

k = 180$
Substituting the value of k we have that the inverse variation is:
$y = 180 / x
$
For y2 = 3 we have:
$3 = 180 / x2
$
Clearing x2 we have:
$x2 = 180/3$
$x2 = 60$
Answer:
$x2 = 60$

An executive invests $27,000, some at 8% and the rest at 7% annual interest. If he receives an annual return of $2,050, how much

Ierofanga [76]

8%X + 7%(27000-X) = 2050
.08X + 1890 + .07X = 2050
.15X = 160
X = $1067.67
