It is A) horizontal. The directix lies directly above the vertex of a parabola, and it is a straight horizontal line.
Hope it helps :)

A) because the directix it the line in which the parabola does not pass through so it can only go though the horizontal because the parabola never ends given that its a line and it slanted so it will always pass through the y axis but if the vertex is above the x axis then it will never pass below it.

F(x) =17x and g(x) = 4x. Find f(x)-g(x) when x=3

bogdanovich [222]

Answer:

Step-by-step explanation:

f(x)=17x

f(3)=17(3)

f(x)=51

g(x)=4x

g(3)=4(3)

g(x)=12

f(x)-g(x)

51-12= 39

An ol television was sold for $30 at a loss of20%. find cost in price with explanation

marusya05 [52]

Well I’m guessing it went down by 20% to get to thirty pounds so

30 x 1.2 = $36 original price

Or if it’s lowered by 20% then

30 x 0.8 = $24

Of great importance to residents of central Florida is the amount of radioactive material present in the soul of reclaimed phosp

alukav5142 [94]

Answer:

See figure attached and explanation below.

Step-by-step explanation:

For this case we have the following dataset given:

0.74, 0.32, 1.66, 3.59, 4.55, 6.47, 9.99, 0.7, 0.37, 0.76, 1.9, 1.77, 2.42, 1.09, 2.03, 2.69,2.41, 0.54, 8.32, 5.70, 0.75, 1.96, 3.36, 4.06, 12.48

And for this case we can use the followinf R code to create the frequency histogram.

> x<-c(0.74, 0.32, 1.66, 3.59, 4.55, 6.47, 9.99,0.7, 0.37, 0.76, 1.9, 1.77, 2.42, 1.09, 2.03, 2.69,2.41, 0.54, 8.32, 5.70, 0.75, 1.96, 3.36, 4.06,12.48)

> length(x)

[1] 25

> hist(x, prob=TRUE)

And for this case we have the histogram on the figure attached. For the number of classes we use the formula of sturges:

$k = 1 +3.322 log (n)= 1+3.3 log(25)= 5.61$

And for this case we have approximately 6 classes. And that's what we can see on the figure attached

As we can see most of the values are on the left so then we have a right skewed to the right and the distribution is assymetrical, with most of the values between 0 and 6
