Answer:
DAB = 53
Step-by-step explanation:
ABC is congruent to ABD
Therefore
CAB = DAB
ABC = ABD
And
BCA =BDA
We are looking for angle DAB
We know CAB is 53, and that CAB = DAB
DAB = 53
Answer:
As I understand it asks for (fog)(x)
We know f(x)= 2x + 2
And g(x) = x^2 + 1
It is going to be like we are putting g(x) inside the f(x).
So you are going to write g(x) wherever you see a x.
Step-by-step explanation:
f(x)= 2x + 2 <-- do you see the x there, so just wrote g(x) formula instead of x.
g(x) = x^2 + 1
So, it will look like this:
(fog)(x) = 2(x^2 + 1) + 2
You also can simplify this with multiplying by 2 in front ; 2x^2 + 2 +2 and you can add two 2s finally it will be, 2x^2 +4
Hope it was clear, let me knoq if you have any questions.
The top base is : 14mm
The bottom base is: 36mm
The height is: 15mm
First you need to add the top and bottom bases together and divide it by 2
(14mm + 36mm) / 2
= 50mm/2
=25mm
Then you need to times it by the height
25mm x 15mm = 375mm^2
<span>Assuming the reaction is of 1st order, we can
start using the formula for rate of 1st order reaction:</span>
dN / dt = k * N
Rearranging,
dN / N = k dt
Where N = amount of sample, k = rate constant, t = time
Integrating the equation from N = Ni to Nf and t = ti to
tf will result in:
ln (Nf / Ni) = k (tf – ti)
Since k is constant, we can equate to situations.
Situation 1 is triple in size every days, situation 2 is after 20 days.
ln (Nf / Ni) / (tf – ti) = k
ln (3Ni / Ni) / 4 = ln (Nf / 40) / 20
Calculating for Nf,
