The zeros of a quadratic function are 4 and 8. What is the axis of symmetry of the function?

1 answer:

3 0

So if you want to have a factored form...

If the zeroes are +4 and +8, you would write
(X-4) (x-8)
Then you would multiply it out to get to quadratic form...

So, (x-4)*(x-8)
X^2 - 12x + 32

Then you would plug it into the formula for axis of symmetry...
X= -b/2a

X=12/2 = 6

X=6

Can someone tell me what 5/9 + 4/6 = in fractions

Katyanochek1 [597]

Answer:

1 2/9 or 1.2222222222222

Step-by-step explanation:

5/9 + 4/6

= 5 * 2/9 * 2 + 4 * 3/6 * 3

= 10/18 + 12/18

= 10+12/18

=22/18

= 22 ÷ 2/18 ÷ 2

= 11/9 = 1 2/9

A criminologist developed a test to measure recidivism, where low scores indicated a lower probability of repeating the undesira

Citrus2011 [14]

Answer:

157.6

Step-by-step explanation:

The formula for calculating a z-score is is z = (x-μ)/σ,

where x is the raw score,

μ is the population mean, and

σ is the population standard deviation.

From the question:

Mean = 140

Standard deviation = 40

Recidivism score = x score = ??

z = z score of 67th percentile = 0.44

Hence,

0.44 = x - 140/40

Cross Multiply

0.44 × 40 = x - 140

17.6 = x - 140

x = 140 + 17.6

x = 157.6

Therefore, his corresponding recidivism score is 157.6

Help please! any1 know this

ra1l [238]

Answer:

C, 3

Step-by-step explanation:

By creating a best line of fit you can get the sets of points (16,50) and (12,40)

Using these to find the slope we can get $\frac{40-50}{12-16} =\frac{-10}{-4}$

-10/-4 is 2.5 The best approximation would be C, because if you round it up to the nearest number you would get 3.

Solve 10 + 6(–9 – 4x) = 10(x – 12) + 8

Leviafan [203]

1. 10 + 6(-9-4x)=10(x-12)+8
2.10 +-45-24x=10x-120+8
3.10 +7 = 34x -120 +8
4.17=34x-120+8
5.17=34x +128
6. 34x=115
7.x= 0.29565217391
