Answer:
there is a 0.02 or 2% difference
Answer:
a) 
b) 
Dividing both sides by 0.448 we got:

We can appy the exponent
in both sides of the equation and we got:

Step-by-step explanation:
For this case we know the following function:

The notation is: x is the weight of the crab in grams, and the output f(x) is the weight of the claws in grams.
Part a
For this case we just need to replace x = 2 gram in the function and we got:

Part b
For this case we know tha value for
and we want to find the value of x who satisfy this condition:

Dividing both sides by 0.448 we got:

We can appy the exponent
in both sides of the equation and we got:

Every point in the unit circle is identified either by its coordinates
or by the angle it forms with the x-axis,
.
The trigonometric functions associate with every angle
and the correspondant
coordinates the two values

This procedure can be done for every angle
, so you don't have to work with acute angles only.
Answer: A
Step-by-step explanation:
The answer is a because the measure of angle KGH is 25 degrees since it is an inscribed angle. Angle GKJ is 130 degrees because angle GKL is 50 degrees. Therefore angle J is equal to 25 degrees which makes the triangle an isosceles triangle since angle J and angle KGH are equal to one another.
