It has to be A) Right Isosceles because 2 of the sides are the same length,
Hope this helps!!
Answer:

Step-by-step explanation:
Ana started the work nicely by multiplying out factors to get:\
She multiplied 
correctly using difference of two squares to get: 
Unfortunately: She made a mistake in multiplying 
she mistakenly got 
instead of 
. <em>She left out the coefficient of 2.</em>
Therefore the second step should have been:
The next step will now be:
This simplifies to
We have that the data have a high point at the start (4). Then, it drops to a lowest point (3) and then it increases again. Hence, an exponential fit is a bad idea; exponential functions are always increasing. The same applies to square root functions, they are always decreasing or increasing and they do not have up and downs.
A quadratic function is the most appropriate function to model the data. While it is true that also cubic functions can act like this, the simplest choice is quadratic functions; they have a lowest dip and then they increase on either side of the dip, just like the data.
The correct answer is d.
Answer: 38.46
Step-by-step explanation:
Answer:
Perimeter = 12.0 m
Step-by-step explanation:
Perimeter = AB + AC + BC
AB = 5 m
B = 53°
Use trigonometric functions to find AC and BC respectively.
✔️Find AC:
Reference angle = 53°
Opposite side length = AC
Hypotenuse = 5 m
Apply SOH, which is:
Sin 53 = Opp/Hyp
Sin 53 = AC/5
5*Sin 53 = AC
AC = 3.99317755 ≈ 4 m
✔️Find BC:
Reference Angle = 53
Hypotenuse = 5 m
Adjacent = BC
Apply CAH, which is:
Cos 53 = Adj/Hyp
Cos 53 = BC/5
5*Cos 53 = BC
BC = 3.00907512 ≈ 3.0 m
✔️Perimeter = 5 + 4 + 3 = 12.0 m
