It is a.
You multiply 9.3 and 2.5 together and get 23.25
Then just add the exponents 6+3 is 9
So the answer is 23.25 x 10^9
Hope this helps!!
HK consists of two part, HJ and JK
HK = HJ + JK
We know that:
HK = 12.2ft
JK = 3.1ft
HJ = ?
Let's plug our values into the equation above.
12.2ft = HJ + 3.1ft
Subtract 3.1ft from both sides.
9.1ft = HJ
Answer:
16:40 24:60 32:80
Step-by-step explanation:
Answer:
Option a.
Step-by-step explanation:
By looking at the options, we can assume that the function y(x) is something like:


such that, y(0) = √4 = 2, as expected.
Now, we want to have:

replacing y' and y we get:

Now we can try to solve this for "a".

If we multiply both sides by y(x), we get:


We can remove the x factor in both numerators if we divide both sides by x, so we get:

Now we just need to isolate "a"


Now we can subtract a*x^2 in both sides to get:

Then the solution is:

The correct option is option a.
Answer:
31°
Step-by-step explanation:
The theorem states that all angle sums of any triangle add up to 180°.
128 + 21 = 149, and to find ?°, subtract 149 from 180 to get 31°.
