If what it's trying to say is 48b=3926 then the answer would be 81.8. All you have to do is divide 3926 by 48, however I don't know if that's exactly what's trying to be said

F(x) = 2x2 + 12x + 1<br> Determine the vertex !

stealth61 [152]

Answer:

(-3, -17)

Step-by-step explanation:

The best way to find the vertex is to rewrite the given quadratic in vertex form: y - k = a(x - h)^2.

The given quadratic is f(x) = 2x2 + 12x + 1. We will focus on the first two terms and "complete the square." f(x) = 2x2 + 12x + 1 can be rewritten as

f(x) = 2(x^2 + 6x) + 1, which, after completing the square, is

f(x) = 2(x^2 + 6x + 9 - 9) + 1, or

f(x) = 2( (x + 3)^2 - 9 ) + 1, or

f(x) = 2(x + 3)^2 - 17

Comparing this to

f(x) = a(x - h)^2 + k, we see that the vertex is located at (h, k): (-3, -17)

What is the velocity of an object dropped from a height of 180 m when it hits the ground?

Helen [10]

You can use this formula: <span>vf^2=0+2(9.8)(M)
solve it out like so:
vf^2=0+2(9.8)(180)
vf^2=2(1764)
vf^2=3528
now, square both sides to cancel out the power of 2. you are left with:
about 59.4 m/s</span>

a recent study showed that the average high school basketball team score 76 points a game with a standard deviation of 8.4 point

krok68 [10]

Answer: 0.0766

Step-by-step explanation:

Let x be the random team scores.

Given: Mean = 76

Standard deviation = 8.4

We assume that x follows normal distribution.

The probability that a random team scores less than 64 points = P(x<60)

$=P(\frac{x-\mu}{\sigma}$

Hence, the probability that a random team scores less than 64 points =0.0766

What is the next number in the pattern below? 3, 5, 9, 15, 23, ___ 31 33 35 37

DaniilM [7]

Each term in this pattern is created by adding consecutive multiples of 2 to the previous term.
$a_1=3 \\
a_2=3+ 2 \times 1=5 \\
a_3=5+2 \times 2=9 \\
a_4=9+2 \times 3=15 \\
a_5=15+2 \times 4=23$

You can write the formula for this pattern as:
$\left \{ {{a_1=3} \atop {a_n=a_{n-1}+2(n-1)}} \right.$

The next number is $23+2 \times 5=23+10=33$ .
The answer is 33.
