Answer: 88meters

Step-by-step explanation:

make a direct variation

so if a 2.8 meter building casts a 1.61 shadow then

2.8/1.61

and if a unknown building mark that as x gives a 50.75 shadow then

2.8/1.61=x/50.75

the you cross multiply that would give you 1.61x=142.1

then divide both sides by 1.61 you get x=88.2608696

But since it say round to the nearest meter you round to 88!

Hello!


The graph, (2/5)^x is an exponential function.


Since there is not a negative symbol in the front of the function, options A and B are incorrect.


For option 3 to be correct, there would need to be a negative symbol in front of the exponent, x.


So therefore, the answer option 4. (Also, I'll post a graph. :))

irinina [24]

Answer:

Mean: 21

Median: 23

Mode: 27

Step-by-step explanation:

order from least to greatest:

1, 15, 18, 22, 23, 25, 27, 27, 31

mean: add all the numbers and divide by 9 bc thats how many numbers there are so that means the answer is

21

Median: to find the median you order the numbers from least to greatest and find out the middle number so in that case the median is 23

Mode: to find the mode you look to see what number is repeated multiple times, so the mode is 27

Answer:

y = -1/4x^2 - x + 3

Step-by-step explanation:

(-6,0)

(-4,3)

(2,0)

36a - 6b + c = 0

16a -4b + c = 3

4a + 2b + c = 0

c = -4a - 2b

36a - 6b - 4a -2b = 0

16a - 4b -4a - 2b = 3

32a -8b = 0

12a - 6b = 3

4a - b  = 0

4a - 2b = 1

b = -1

4a + 1 = 0

4a = -1

a = -1/4

c = 1 + 2 = 3

y = -1/4x^2 - x + 3
