Answer:
k = 1
Step-by-step explanation:
<u>Discriminant</u>
As we need to determine the value of k that will give <u>one solution</u>, set the <u>discriminant to zero</u>.
<u>Given equation</u>:
Therefore:
Substitute these values into the discriminant and solve for k:
Answer:
12
Step-by-step explanation:
Use the Pythagorean theorem which is a^2 + b^2 = c^2
c is hypotenuse and a and b are the legs
we need to find a^2 so
a^2 + 16^2 = 20^2
a^22 + 256 = 400
then subtract 256 from 400
a^2 = 144
square root 144
= 12
Answer:
It is A, 65
Hope this helps!
The answer is 194.59
(72 x 100) / 37 = 194.59
