Answer:
The perfect -square trinomial
(9y+7)²
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given polynomial equation
81 y² + 126 y +49
⇒ 9² y² + 2(9)(7)y + 7²
⇒ (9y)² + 2(9)(7)y +7²
we will use formula
(a+b)² = a² + 2ab +b²
⇒ (9y+7)²
<u><em>Final answer:-</em></u>
The perfect -square trinomial
(9y+7)²
Answer:
False, True, True, False
Step-by-step explanation:
I'm pretty sure all your answers are right except the second one. I'm no genus or anything like that tho so I'm not sure. Plus I'm not good at graphs. Well depends how it is.
Answer:
<h2>f(3) = 41</h2>
Step-by-step explanation:
f(x) = 5 + 4x²
To find f(3) substitute the value of x that's 3 into f (x) which means for every x in f (x) replace it with 3
That's
f(3) = 5 + 4(3)²
= 5 + 4( 9)
= 5 + 36
We have the final answer as
<h3>f(3) = 41</h3>
Hope this helps you
Answer:
10 years
Step-by-step explanation:
The simple interest formula tells you the relationship between interest, principal, interest rate, and time. When the given values are put into the formula, it can be solved for the unknown time.
__
I = Prt . . . interest earned on principal P at rate r for t years
6000 = 1000·0.60·t . . . . use the given values for I, P, r
6000/600 = t = 10 . . . . divide by the coefficient of t
$1000 will yield an interest of $6000 in 10 years.
