Answer:
x = 120
Step-by-step explanation:
First you want to get the equation into the form cosx = a
2 cos=1
Divide both sides by two to get it into the form.
cos=
Now, on your calculator, use the inverse of cos, to solve for .
=
(
)
= 60
Now you want to find x, so multiply both sides by 2.
x = 60 * 2 = 120
x can have many solutions; however, I have only given you one.
Y is between X and Z
The value of d=2 and the value of YZ = 16
Given :
Y is between X and Z.
XY = 11d, YZ = 9d – 2, XZ = 5d + 28
We need to find the value of d
we know that Y is between X and Z
So,
Replace the given expression and solve for d
The value of d=2
Now we find out YZ using d=2
The value of YZ is 16

In exponential decay, the value under the exponent must be less than 1 and more than 0
but wait, we have exponents that are negative values, that's interesting
it's a trick, we need to convert it to form
remember that
also that
therefor
so those ones that have the -x exponent, we need to flip the fraction
first one is 7/4, that is more than1
2nd one has a negative exponent so it becomes (3/4)(5/4)^x and 5/4 is greater than 1
3rd one has negative exponent so it becomes (3/2)(7/8)^x and 7/8 is less than 1
4th one is 9/2 and that's more than 1
3rd one is answer or
