Just need question # 12. Thanks

Natalka [10]

There are two lines from the center of the circle labeled 5.

The lines at 90 degrees from the 5 are chords. Because both lines are the same distance from the center they are the same length.

The one on the top is labeled as 9, so the line on the bottom is also 9 units long.

X is half the length, so would b 9 /2 = 4.5 units long.

9x^2+6x+5=0, solve using the quadratic formula

AleksAgata [21]

Step by step explanation:

9 $x^{2}$ +6x+5=0

Uses the "a", "b", and "c" from "a $x^{2}$ + bx + c", where "a", "b", and "c" are numbers

So in this case:

a would be 9

b would be 6

c would be 5

Then plug in from there..

Another way you can do it is using the square method.

Write the expression in factored form

olchik [2.2K]

$2.)\\ \\ n^2 - 9n +14 = 0 \\ \\ a=1 , \ b = -9, \ c = 14 \\ \\\Delta =b^2-4ac = (-9)^2 -4\cdot1\cdot 14 = 81 -56 = 25 \\ \\n_{1}=\frac{-b-\sqrt{\Delta} }{2a}=\frac{9-\sqrt{25}}{2 }=\frac{ 9-5}{2}=\frac{4}{2}= 2$

$n_{2}=\frac{-b+\sqrt{\Delta} }{2a}=\frac{9+\sqrt{25}}{2 }=\frac{ 9+5}{2}=\frac{14}{2}= 7 \\ \\ Answer : \ n^2 - 9n +14 =(n-2)(n-7)$

$3.)\\ \\ n^2 + 4n - 12 =0 \\ \\ a=1 , \ b = 4, \ c = -12 \\ \\\Delta =b^2-4ac = 4^2 -4\cdot1\cdot (-12) = 16+48=64 \\ \\n_{1}=\frac{-b-\sqrt{\Delta} }{2a}=\frac{-4-\sqrt{64}}{2 }=\frac{ -4-8}{2}=\frac{-12}{2}= -6$

$n_{2}=\frac{-b+\sqrt{\Delta} }{2a}= \frac{-4+\sqrt{64}}{2 }=\frac{ -4+8}{2}=\frac{4}{2}=2\\ \\ Answer : \ n^2 +4n -12 =(n+6)(n-2)$

second way :

$2.)\\ \\ n^2 - 9n +14 = n^2 - 9n+2n -2n +14 = n^2 - 7x -2n +14 =\\ \\ = n(n-7)-2(n-7)=(n-7)(n- 2)\\ \\ \\ Answer : \ n^2 - 9n +14 =(n-2)(n-7)$

$3.)\\ \\ n^2 + 4n - 12 = n^2 + 4n +2n - 2n - 12 = n^2 + 6n - 2n - 12 =\\ \\ = n(n+6) -2(n+6)=(n+6)(n-2) \\ \\ \\ Answer : \ n^2 +4n -12 =(n+6)(n-2)$

If the weight (in grams) of cereal in a box of lucky charms is n(479,4), what is the probability that the box will contain less

ivolga24 [154]

Answer:

about 8.8×10⁻⁵

Step-by-step explanation:

This probability is best found using a probability calculator of some sort. The z-score is ...

... (464-479)/4 = -3.75

You will have to search a bit to find a probability table that lists probability values for z-scores beyond ±3.00.
