What change(s) should Sylvia make to the equation to find the value of t in the above scenario?
finlep [7]

Answer:

Option (D).

Step-by-step explanation:

Initial population of the deer P_{0} = 4800

Decrease in the population of the deer after every 8 years = \frac{1}{2}\times (\text{Initial population})

Decrease in population is an exponential process, so the expression representing population will be,

P_{t}=P_{0}(1-r)^x

Where P_{t} is the population after 'x' slots of 8 years.

r = fraction of decrease in the population

x = \frac{\text{Number of years}}{8}

By substituting the values of r and x in the expression,

P_{t}=P_{0}(1-\frac{1}{2})^{\frac{t}{8}}

P_{t}=4800(\frac{1}{2})^{\frac{t}{8}}

Therefore, Sylvia should do few corrections in her expression.

(8) should be replaced by (\frac{1}{2}) and \frac{t}{2} should be replaced by \frac{t}{8}.

Option D. will be the answer.

What is the median of the data set?
Arturiano [62]
First we need to arrange the numbers in this number set from smallest to biggest:17,18,24,27,31,39,42,47,55,65. Then there are 10 numbers in this number set. So when we calculate the median, we need to find the middle two numbers and calculate their average. So the median is (31+39)/2=35. SO the answer is B

-x + y = 8
podryga [215]

Answer:

No solution

Step-by-step explanation:

-x + y = 8..............(1)

1/2x - 1/2y = 3......(2)

Multiply (2) by 2

x - y = 6 ............(3)

Adding (1) and (3)

-x + x + y - y = 8 + 3

x and y are both eliminated so no solution

Mark bought gifts for his friends, and each gift cost $9. Let y represent the total cost and x represent the number of gifts. Wr
olga nikolaevna [1]

Answer:

y = 9x

Step-by-step explanation:

You can set up linear equations like this: y = mx + b, where m is the slope or rate, and b is the y-intercept.

9 would be the slope, since he has to pay $9 per gift.

The y-intercept is when x = 0, but if he doesn't buy any gifts, he won't have to pay anything, so b = 0. You don't have to include it since it's 0.

So, it's just y = 9x

Hope that helps! :D

Write g(x) = 4x2 + 88x in vertex form. The function written in vertex form is g(x) = (x +11)2 + .
romanna [79]

Answer:

y = 4(x + 11)² - 484

Step-by-step explanation:

y = 4x² + 88x

factor the expression

y = 4(x² + 22x)

complete the square

y + ? = 4(x² + 22x + ?)

y + ? = 4(x² + 22x + 121)

add 4 • 121 to the left side

y + 4 • 121 = 4(x² + 22x + 121)

multiply

y + 484 = 4(x² + 22x + 121)

y + 484 = 4(x + 11)²

subtract both sides by 484

y = 4(x + 11)² - 484
