onsider the equation 0.5 times e4z =13 solve the equation for z. express the solution as a logarithm in base e

olga_2 [115]

Answer:

$z=\frac{ln(26)}{4}$

Step-by-step explanation:

The given equation is:

$0.5\,e^{4z}=13$

so, we first isolate the exponential form that contains the unknown "z" in the exponent, by dividing both sides by 0.5:

$0.5\,e^{4z}=13\\e^{4z}=\frac{13}{0.5}\\e^{4z}=26$

Now we bring the exponent down by applying the natural log function on both sides, and then solve for "z":

$e^{4z}=26\\ln(e^{4z})=ln(26)\\4\,z=ln(26)\\z=\frac{ln(26)}{4}$

Evaluate the expression: a(b – c) if a = -8, b = 12, and c = 4

Llana [10]

Answer:

-64

Step-by-step explanation:

a(b - c)

a = -8

b = 12

c = 4

So, you'd plug in those numbers:

-8(12 - 4)

You'd start within the parenthesis's, so:

(12 - 4), which equals (8)

-8(8)

= -64
