In any function, f(x) = a(x-h)n + k , a negative leading coefficient means the graph is reflected. True or False

Temka [501]

Answer:

True

Step-by-step explanation:

For any function of the form $f(x) = a(x-h) ^ n + k$ the coefficient a produces a reflection of the function whenever $a$ .

We can verify it in the following way.

Take, for example, the function:

$f(x) = 2(x-1) ^ 3$

Now let's make $f(2)$

$f(2) = 2(2-1)^3\\\\f(2) = 2$

Now let's $f(2)$ in the following function:

$f(x) = -2(x-1)^3$

We have:

$f(2) = -2(2-1)^3\\\\f(2) = -2$

We can see then that the function was reflected in the axis -y by placing a negative coefficient a.

You can see more examples in the attached images

Therefore we can conclude that the statement is true.

Halla la medida del lado de un cuadrado cuya diagonal es de 14 cm

8_murik_8 [283]

Answer:

The length side of the square is $7\sqrt{2}\ cm$

Step-by-step explanation:

<u><em>The question in English is</em></u>

Find the measure of the side of a square whose diagonal is 14 cmd

Let

d ----> the diagonal of a square in cm

b ---> the length side of a square in cm

we know that

Applying the Pythagorean Theorem

see the attached figure to better understand the problem

$d^2=b^2+b^2$

$d^2=2b^2$

we have

$d=14\ cm$

substitute the given value

$14^2=2b^2$

solve for b

$196=2b^2$

$98=b^2$

take square root both sides

$b=\sqrt{98}\ cm$

simplify

$b=7\sqrt{2}\ cm$

Answer:

P(T<683) = 0.1587 = 15.87% ≈ 16%.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Sum of normal variables:

When two normal variables are added, the mean is the sum of the means, while the standard deviation is the square root of the sum of the variances.

The weights of these candles have a mean of 500g and a standard deviation of 15g. The weights of the candle stands have a mean of 200g and a standard deviation of 8g.

The package consists of one candle of each type. So

$\mu = 500 + 200 = 700$
