A population of 805 cheetahs decreases by 10% per year. How many cheetahs will there be in the population after 6 years?

Phantasy [73]

Answer:

Step-by-step explanation:

y = a(b)^x

a would represent the initial value.

b would represent the change

x represents the number of years

y = 805(0.9)^6

y = 805(0.531441)

y = 427.8

y = 427 cheetahs

Six football players, all defensive linemen, decide that they'll gain an average of 10 pounds over the summer. At the start of t

noname [10]

Answer: b. 14 pounds

Step-by-step explanation:

Formula to calculate average :

$\text{Average}=\dfrac{\text{Sum of all observations}}{\text{Number of observations}}$

Let x denotes the number of pounds the last person have to gain so that the group can attain its goal.

Required average = 10 pounds

Observations = 9, 13, 11, 6, 7 and x (pounds)

Number of observations= 6

Sum of all observations = 9+13+ 11+ 6+7+x=46+x

According to the question , we have

$10=\dfrac{46+x}{6}\\\\ 46+x=10\times6\\\\ 46+x=60\\\\ x=60-46=14$

i..e the last person has to gain 14 pounds so that the group can attain its goal.

Hence, the correct answer is b. 14 pounds .

I’m having a lot of trouble with this question

Allushta [10]

Answer:

Function C has the greatest initial value

Function B has the greatest rate of change

Step-by-step explanation:

C is greatest for initial value because the line intercepts at 2 and i think B intercepts at -1 then as u can see A intercepts at 0 or origin

B is the greatest rate of change or slope because it goes up by 3 and then A goes up by 5/2 and C goes up by 1/3

Please can you help me??

yulyashka [42]

Answer:

Step-by-step explanation:

you put the -9 above where it says the -9 and same to the -3

or to solve the equation:

Divide both sides of the equation by the same term

−9=−3−9−3=−3−3

Divide the numbers

−9−3=−3−3

3=−3−3

Cancel terms that are in both the numerator and denominator

Move the variable to the left =3x=3

Solution =3
