Answer:
e^2 -7 = x
Step-by-step explanation:
2=ln(x+7)
Raise each side to the base of e
e^2 = e^ln (x+7)
The e^ln cancel
e^2 = x+7
Subtract 7 from each side
e^2 -7 = x +7-7
e^2 -7 = x
To set up this let's add all the milligrams together
(1)225×(2)0.125×(1)0.75=226
the total daily dosage is 226 milligrams
I hope I've helped!
Answer:
3. 
Step-by-step explanation:
All the polynomials in the given option are quadratic.
By the fundamental theorem of algebra, the quadratic polynomial has two roots.
Since the solution set is given as {5}, the quadratic has a repeated root.
In other words the root has a multiplicity of 2.
Hence we have the equation:
, multiplicity 2
This implies that;

We expand to obtain;


The correct choice is the third option.
Answer:
False; True; True
Step-by-step explanation:
If the radius is 4, the area of the circle is
pi*r*r = pi * 4 * 4 = 16pi; The second statement is true.
The entire circle's "angle" is 2pi, so the sector takes (2pi/3) / 2pi of it all, equal to 1/3 of the entire circle - hence the area of the sector is
16pi * 1/3 = 16pi/3; the first statement is false
The length of the entire circle is 2 * pi * r = 2 * pi * 4 = 8pi
The sector is 1/3 of that, so 8pi/3; the third statement is true.
$10.50 for the folders
the change would be $3.50
multiply 14x.75 to get 10.50
subtract 10.50 from 15
