F(x) = 3(x-6)²+1
This is an up-opening parabola with vertex (6,1).
Range: [1,+∞)

Oh, I SEE what da pattern is! =D
You see, like in this problem:
2 + 5 = 12
They did 5 times 2 = 10, plus da 2 in da problem = 12.
Same with 3 + 6 = 21, 6 times 3 = 18, 18 plus da 3 given in da problem = 21.
Just like 1 + 4 = 5, 4 times 1 = 4, plus da 1 in da problem = 5.
SO,
with that strategy, 8 +11 = 96, because 8 times 11 = 88, plus da 8 given in da problem = 96.
I hope I helped! =D

ABC is an isosceles AB= 3x-4 and BC= 5x-10 what is AB?

kakasveta [241]

3x-4=5x-10
Subtract 3x from both sides
-4=2x-10
Add 10 to both sides
6= 2x
X= 3
3 times 3-4
AB=5

Given the equation:

Alisiya [41]

Answer:

x = 1 and x = $\frac{-4}{5}$

Step-by-step explanation:

In this equation, a=5, b=-1, c=-4.

Plug these into the quadratic formula:

x = $\frac{1+\sqrt{-1^{2}-(-4)(5)(-4) } }{2(5)}$ and x = $\frac{1-\sqrt{-1^{2}-(-4)(5)(-4) } }{2(5)}$

Now, simplify the equations:

x = $\frac{1+\sqrt{81} }{10}$ = $\frac{1+9}{10}$ = $\frac{10}{10}$ = 1

and

x = $\frac{1-\sqrt{81} }{10}$ = $\frac{1-9}{10}$ = $\frac{-8}{10}$ = $\frac{-4}{5}$

emmainna [20.7K]

Answer:

Step-by-step explanation:

given that a laptop company claims up to 11.0 hours of wireless web usage for its newest laptop battery life. However, reviews on this laptop shows many complaints about low battery life. A survey on battery life reported by customers shows that it follows a normal distribution with mean 10.5 hours and standard deviation 27 minutes.

convert into same units into hours.

X is N(10.5, 0.45)

a) the probability that the battery life is at least 11.0 hours

$P(X\geq 11)\\\\=1-0.8667\\=0.1333$

(b) the probability that the battery life is less than 10.0 hours

= $P(X$

=97th percentile

= 11.844

d) The time of use that is exceeded with probability 0.9 is

is 90th percentile = 10.885
