If William has 195 marbles, let's find 4/5 of that.
195 * 4/5 = 156
156 is 2/5 of the marbles Daniel has.
Now we must multiply by the reciprocal
156 * 5/2 ( to find all of Daniel's marbles, not just 2/5) = 390 marbles
Daniel has 390 marbles.
we are given

we know that
whenever nothing is given in base
we will assume base =10

so, we can solve for x
we can take exponent 10 on both sides

now, log will be cancelled with 10
we get

Answer:
The inner function is
.
The outer function is
.

Step-by-step explanation:
The inner function is the one we apply the outer function to.
So

We apply the outer function tangent to
.
So, the inner function is
.
The outer function is
.
The derivative of a compositve function
in which
is given by the following function.

Answer:
A. -11
Step-by-step explanation:
In the function, replace x with -2
R(x) = x^2 - 3x - 1 ➡ R(-2) = (-2)^2 - 3 × 2 -1 = -11
