The 1st one: y=(1.008¹/¹²)¹² →y=(1.008⁽¹/¹²⁾⁽¹²⁾ = y = 1.008¹. No change
The 2nd one: y=(2500+0.004)^t → Growth
The 3rd one: y=[(1-0.004)¹/₅₆]⁵⁶ → Decay
Tfe 4th one y= 12,00(1/2)^t → Decay
Let us assume base of the window = b feet.
Height is 3 feet less than base, that is = (b-3).
Given area of the triangle = 20 feet square.
We know formula for area of a triangle:
Area = × Base × Height
Plugging values in formula, we get
20 =
Factoring quadratic, we get
=0
b+5=0
b=-5
b-8=0
b=8.
For base we can take only positive value.
<h3>Therefore, base of the triangle = 8 feet and height = 8 -3 = 5 feet.</h3>

Answer:
a2 - ab + 2b2
Step-by-step explanation:
Answer:
Step-by-step explanation:
So we know that:
Recall that tangent represents the side opposite over the side adjacent.
This means that the opposite side is 3 while the adjacent side is 4.
Therefore, by using the Pythagorean Theorem, we can solve for the third side, which is the hypotenuse:
Substitute a for 3 and b for 4. Thus:
Square and add:
Square root:
Now, recall that cosecant is the reciprocal of sine. So, find sine first.
Sine is opposite over hypotenuse. From tangent, the opposite is 3 and the hypotenuse as we now know is 5. Thus:
And cosecant is the reciprocal of that. Thus:
And that's our answer :)
