Solve. -1/8c=2
a. 4
b. –16
c. –4
d. 16

Answers

$(-1)/(8c) =2$
This requires that c ≠ 0 , meaning c≠0
$(-1)/(8c) =2$
Multiply by x to eliminate var in denominator
$( \not c*(-1))/( 8 \not c) =c*2$
$(-1)/(8) =c*2$
Common denominator is 8
$(\not 8(-1))/(\not 8) =8c*2$
$-1=8c*2$
$-1=16c$
$x=-16$
The answer is: b. -16

if the equation is h= -2x^2 + 12x -10

how do I find the max height?

Answers

One other way to solve this question is finding the derivative

$h=-2x^2+12x-10$

$h'=-4x+12$

now we have to find when this function will be zero

$-4x+12=0$

$\boxed{\boxed{x=3}}$

now we just replace this value at our initial function

$h=-2x^2+12x-10$

$h_(max)=-2*(3)^2+12*3-10$

$h_(max)=-18+36-10$

$\boxed{\boxed{h_(max)=8}}$

The maximum height is the ordinate value of the vertex of the parabola, ie: yV

Calculating yV:

$y_V=(-\Delta)/(4a)\n \n y_V=-[(12^2-4*(-2)*(-10)])/(4*(-2))=(-(144-80))/(-8)=(-64)/(-8)=8$

Enter the value of p so the expression 5/6 - 1/3n is equivalent to p(5-2n).

Answers

Let's solve for p when the two expressions are equal.

$p(5-2n)=\frac{5}6 - \frac{1}3n \n\n p=\frac{\frac{5}6-\frac{1}3n}{5-2n}*\frac{6}6= (5-2n)/(6(5-2n)) = \boxed{\frac{1}6}$
