Answer:
{-1, 5} (two real solutions).
Step-by-step explanation:
On the left side we want x^2, not x?
We need to rewrite x? = 4x - 5 in standard form, that is, as a quadratic with x terms in decreasing powers of x:
x^2 - 4x + 5 = 0
This factors easily to (x - 5)(x + 1) = 0.
We let each factor equal zero (0) separately and solve for x:
{-1, 5} (two real solutions).
Answer:
1000
Step-by-step explanation:
After 8 hours, it becomes 1000, and because it doesn’t make it to 16 hours it stays at 1000.
Answer:
B.)$80
5.29 times 16.3 is 86.227 but it is not close to 21 not 165 and not a 800 so the answer would be 80
Hyp^2 = leg1^2 + leg2^2
hyp^2 -leg1^2 = leg2^2
17^2 - 8^2 = leg2^2
leg2^2 = 289 -64
leg2^2 = 225
leg2 = 15
Im not sure just give me a minute
