Given f(x)=x^2+5 and g(x)=2x^3-1 find (f/g)(-3)

AlekseyPX

For this case we have the following functions:

$f (x) = x ^ 2 + 5\\g (x) = 2x ^ 3-1$

By definition of composition of functions we have:

$(f / g) (x) = \frac {f (x)} {g (x)}$

Then substituting:

$f (-3) = (- 3) ^ 2 + 5 = 9 + 5 = 14\\g (-3) = 2 (-3) ^ 3-1 = 2 (-27) -1 = -54-1 = -55$

So:

$(f / g) (- 3) = \frac {14} {- 55} = - 0.25$

Answer:

$(f / g) (- 3) = \frac {14} {- 55} = - 0.25$

If log 2^x = log 3, then which is the value of x?

natulia [17]

There's a property of logs I want you to remember, that is:

log(a)ᵇ = b*log(a)

We'll be using this property to solve the question

<u>Finding x:</u>

log(2)ˣ = log(3)

x*log(2) = log(3) [using the property mentioned above]

x = log(3) / log(2) [dividing both sides by log(2)]

Hence, the correct answer is option E.

For what value of b do the lines bx+3y=10 and x–2y=4 intersect at a point on the x-axis?

MatroZZZ [7]

Answer:

b=2.5

Step-by-step explanation:

every point on x axis has y coordinate =0

so bx=10

x=4

4b=10

b=10/4=5/2=2.5
