Answer:
Option 2) 82°
Step-by-step explanation:
The dilation means the enlargement of the figure or reduction in the size of the figure.
If the scale factor is greater than 1, its an enlargement
If the scale factor is smaller than 1, it is a reduction.
But what ever be the case,
the triangles always remain similar.
Hence the size of the sides changes,
But the size of the angles always remains the same.
Now the largest angle of triangle ABC is 82°.
Hence the largest angle of the triangle DEF shall be 82°.
Second option 82° is the right answer.
As you know, to get the inverse of any expression, we start off by switching the variables about and then solving for "y",
Answer:
17/2
Step-by-step explanation:\
7 3/2 is equal to 17/2 because 2 x 7 is 14 and 14+3 is 17 and you keep the dem so its 17/2 and you cant simplify so it just becomes 7 3/2. i hope this helped.
Answer:
The function that represents the mass of the sample after t days is
.
The percentage rate of change per hour is of -2.46%.
Step-by-step explanation:
Exponential amount of decay:
The exponential amount of decay for an amount of a substance after t days is given by:

In which A(0) is the initial amount, and r is the decay rate, as a decimal.
Element X is a radioactive isotope such that its mass decreases by 59% every day. The experiments starts out with 390 grams of Element X.
This means, respectively, that 
So



The function that represents the mass of the sample after t days is
.
Hourly rate of change:
Decreases by 59% every day, which means that for 24 hours, the rate of change is of -59%. So
-59%/24 = -2.46%
The percentage rate of change per hour is of -2.46%.
