Answer:
about 21.3
Step-by-step explanation:
I found the hypotenuse value by doing the Pythagorean theorem.
a^2+b^2=c^2.
"a" and "b" are the values of the legs, and "c" is the value of the hypotenuse. So, "a" is 14 and "b" is 16.
14^2+16^2=c^2
196+256=452.
Now, I found the square root of 452. The square root of 452 is 21.26029163. This value rounded to the nearest tenth is 21.3.
In conclusion, the length of the hypotenuse rounded to the nearest tenth is 21.3 inches.
Answer:
-12i^2 + i +6
Step-by-step explanation:
(2 + 3i)(3-4i)
6 - 8i + 9 i - 12i^2
combine like terms
-12i^2 + i + 6
Hope this Helps!!!
replace the numbers given for x & y so
the equation becomes 3*(-3) + 2*(-4) =
3*-3 = -9
2*-4 = -8
-9 + -8 = -17
Yes choice D is the correct answer. Nice job.
If you wanted, you can simplify the linear approximation L(x)
L(x) = f(a) + (x-a)*f'(a)
L(x) = f(-0.5) + (x-(-0.5))*f'(-0.5)
L(x) = 2 + (x+0.5)*4
L(x) = 2+4x+2
L(x) = 4x+4
Then plug in x = 0
L(x) = 4x+4
L(0) = 4(0)+4
L(0) = 4
But your method is a shorter route.
