Suppose the function H(t) = 8.5sin(0.017t – 1.35) + 12 models the hours of sunlight for a town in Alaska, where t = 1 is the fir

Vitek1552 [10]

Answer:

3.5 to 20.5 hours

Step-by-step explanation:

The range of the sine function is -1 to 1, so the range of H will be ...

-8.5 +12 = 3.5

8.5 +12 = 20.5

The length of the day varies by 17 hours from 3.5 hours to 20.5 hours.

The diagram shows a scale drawing of a rectangular banner with a scale of 1:30. Calculate

AlexFokin [52]

Answer:

Part 1) The actual length of the banner is $1.2\ m$

Part 2) The area of the banner is $3.24\ m^{2}$

Step-by-step explanation:

we know that

The scale of the drawing is $\frac{1}{30}$

That means ----> 1 cm on the drawing represent 30 cm in the actual

Using proportion

Find out the actual dimensions of the banner

Let

L the actual length of the banner

W the actual width of the banner

For a length of 4 cm in the drawing

$\frac{1}{30}=\frac{4}{L}\\ \\ L=30*4\\ \\L=120\ cm$

Convert the actual length to meters

$L=120/100=1.2\ m$

For a width of 9 cm in the drawing

$\frac{1}{30}=\frac{9}{W}\\ \\ W=30*9\\ \\W=270\ cm$

Convert the actual width to meters

$W=270/100=2.7\ m$

Find the area of the banner

$A=1.2*2.7=3.24\ m^{2}$

the phrase “is a function of” gets used in non-mathematical speech as well as mathematical mathematical speech in sentences like

Tanya [424]

Answer:

Step-by-step explanation:

This is a very interesting question. I'm going to answer no, but don't take that to mean that the question is not worthwhile. It is.

In math, function has the meaning of considering ordered pairs. Here are 4 such ordered pairs.

(1,2)

(2,4)

(1,-3)

(5,9)

They are really not related to one another except all are ordered pairs.

Here's the math definition. If one of the x values (1,2,1,5) has more than 1 y value, you do not have a function.

1 has 2 y values, 2 and -3. Therefore the 4 points do not form a function

if you change the first (1,__) to 0 and your ordered pair becomes (0,2), all is well and you do have a function.

Whether you understand this or not, you have to see that a math function and a biology function are very different. The math function has numbers and those numbers have to obey a rule.

The biology function seems to be saying that how your mom and dad brought you up will determine what foods you like.

Those two uses are very different. How your mom brought you up is related to food. It could be anything else like "Being a knife carrying gang member is a function of where you live."
