Diego's club earns money for charity when members of the club perform community service after school,each student who does commu

Arlecino [84]

Answer:

No

Step-by-step explanation:

Given that:

Amount earned when a student does comminty service = $5

Number of students in club = 12

Amount earned E, is a function of number of members (n) who does community service.

Hence,

E = n * amount earned per member

Is 24 a possible output?

To test, then E = 24

24 = n * 5

24 = 5n

24/5 = 5n/5

4.8 = 5

Hence, 24 is not a possible output, be use number of membwra cannot be a decimal

Express the following quantities as ordinary decimal numbers: (step by step please)

jenyasd209 [6]

Answer:

a. 0.0000009 m

b. 6,130, 000, 000

c. 100,000 light years

d. 0.00001 mm

e. 0.0000010 kg

Step-by-step explanation:

Here, we want to come from the standard form to the decimal form

In doing this, we consider the power of 10 attached

If negative, we count leftwards, if positive, we count right-wards

The number of times we count is the power of 10 attached. The count means we are moving the decimal point

For numbers with out visible decimal point, it is at the back of the most right-ward number

Thus, we have these as;

a. 9 * 10^-7

= 0.0000009 m

b. 6.130 * 10^9

= 6,130, 000, 000

c. 1 * 10^5

= 100,000 light years

d. 1 * 10^-5 mm

= 0.00001 mm

e. 10^-7

= 0.0000010 kg

Does the data below describe a linear, quadratic, or exponential function?

Savatey [412]

Answer:

Quadratic.

Step-by-step explanation:

Both linear and exponential equations are monotone increasing or monotone decreasing functions.

This means that, as the input increases, the output will only increase or only decrease, but never both.

Here for our data, we can see that first we have:

x = -8

y = 13

Then x increases to x = -6, and y decreases to y = 9

Then x increases to x = -4 and y increases to y = 13

Then this function is not monotone increasing nor monotone decreasing, so the data can not describe a linear nor an exponential function.

Then the correct option is quadratic.

An artist is mapping out proposed new features for a triangular reflecting pool. She sketches the pool on grid paper. The coordi

xeze [42]

Answer:

C. (7, 0)

Step-by-step explanation:

Circumcenter of a Triangle

The circumcenter is a point where all the tangent lines of the midpoints of the three sides meet.

The coordinates of the vertices of the pool are (3, 3), (11, 3), and (3, −3). Please refer to the image below where the three midpoints are also shown. Since the triangle is right and two of its sides are parallel to the x-axis and the y-axis, the coordinates of the midpoints are very easy to find

Midpoint of (3, 3), (11, 3)=([3+11]/2,[3+3]/2)=(7,3)

Midpoint of (3,3), (3,-3) =([3+3]/2,[3-3]/2)=(3,0)

The intersection of both lines (shown in red) is the point (7,0) which is also the midpoint of (3,-3), (11,3). Thus this point is where all the midpoints meet.

Answer: C. (7, 0)
