AleksAgata [21]3 years ago
7 0

Answer:

a. 8

b. 248

Step-by-step explanation:

first, find the derivative:

-2x^2 + 32x + 120

= -4x + 32

then, have that equal 0

-4x + 32 = 0

32 = 4x

8 = x

answer a: 8

plug in answer a into the original equation

-2(8)^2 + 32(8) +120

answer b: 248

Plot a graph of the line y = x - 3.<br>Help please ASAP!​
eduard

Step-by-step explanation:

An easy way to plot two points and connect them with line

<u>Point 1</u>

  • x = 0, this gives us y = - 3
  • So (0, - 3)

<u>Point 2</u>

  • x = 3, this gives us y = 0
  • So (3, 0)

Now plot these two points to get the line

17p + 8p3 – 4 – 5(p3 – 2). Don't solve, I just need the simplest form
frutty [35]

Answer:

26p+6

Step-by-step explanation:

17p+8p3-4-5(p3-2)

opening the bracket and multiply by -5

=17p+8p3-4-5p3+10

taking a common factor p

=p[17+(8×3)-(5×3)]+6

solve the simple mathematical calculation

=26p+6

Which is the slope of the like represented by the equation 2x+3y=-12
Burka [1]

slope = - \frac{2}{3}

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

rearrange 2x + 3y = - 12 into this form

subtract 2x from both sides

3y = - 2x - 12 ( divide all terms by 3 )

y = - \frac{2}{3} x - 4 ← in slope- intercept form

with slope m = - \frac{2}{3}

A health department spokesman speaking on a local radio station has advocated that parents download a particular app on their ph
maria [59]

Answer:

Option E is correct.

There seems to be a relationship between the app and preventing the spread of daycare illness.

Step-by-step explanation:

The study was carried out on a sample size of 1200 randomly selected parents and it was discovered that children of parents who downloaded the app, on average, had 10 fewer cases of daycare-related illness during the study period than those whose parents did not download the app.

Examining the options one at a time

a. Because downloading the app seems to decrease child illness, the app should be effective for decreasing child neglect as well.

The study showed that downloading the app seemed to truly decrease daycare-related illnesses in children, but it does not mention anything about child neglect. Hence, this is not a correct conclusion for the study.

b. Downloading the app will cause daycare workers to not spread germs.

The study did not in any way study how the app works, whether it prevents daycare workers to not spread germs, so, this conclusion seems like jumping the gun. It isn't an accurate conclusion of what the study did.

c. The study was an experiment rather than an observational study.

The study was actually more of an observational study. An observational study involves the researchers taking notes and recording the effects of a particular variable or lack of thereof, without interfering with the study.

d. The sample size of the study was too low to determine a result.

A sample size of about 1200 is a large enough sample for the sample characteristics to reflect the population characteristics. So, this statement too isn't true.

e. There seems to be a relationship between the app and preventing the spread of daycare illness.

Based on this information given, it is evident that the results of this study shows a relationship between the app. It shows a significant decrease in daycare-related illnesses in children of parents who downloaded the app. Hence, the app must have something that reduces the chances of a daycare-related illness in the children of parents who downloaded the app.

Hope this Helps!!!
