C. Which is (0,-2).
Plugging in C into the first equation:
y<(x^2) + 2 = (0^2) + 2 = 2 which is greater than -2
[2 > -2]

Then the second eqaution:
y>(x^2) - 6 = (0^2) - 6 = 0 - 6 = -6 which is less than -2
[-6 < -2]

How do you write an exponential equation for this problem
Serhud [2]

Let's think about the information in the problem. The problem tells us a few key points:

  • The number of rabbits grows exponentially
  • We start with 20 rabbits (t = 0, a = 20)
  • After 6 months (t = 6), we have 100 rabbits (a = 100)

Since we know we are going to be working with an exponential model, we can start with a base exponential model:

a = P \cdot r^t

  • P is the principal, or starting amount
  • r is the growth/decay rate (in this case, growth)
  • t is the number of months
  • a is the number of rabbits

Based on the information in the problem, we can create two equations:

20 = P \cdot r^0 = P

100 = P \cdot r^6


The first equation tells us that P = 20, or that we start with 20 rabbits.  Thus, we can change the second equation to:

100 = 20 \cdot r^6

5 = r^6


Now, we don't know r, but we want to, so let's solve for it.

5 = r^6

r = \sqrt[6]{5}


Now, the problem is asking us how many rabbits we are going to have after one year (t = 12), so let's find that:

a = 20 \cdot (\sqrt[6]{5})^{12}

a = 20 \cdot (5^{\frac{1}{6}})^{12}

a = 20 \cdot 5^2

a = 500


After one year, we will have 500 rabbits.

nikdorinn [45]

Answer:

I'm pretty sure the answer would be 102

Step-by-step explanation:

you divide 408 by 4 because the cheeseburgers sold 3x as much as the hamburgers.

AABC - DEF. What sequence of transformations will move A ABC onto A DEF? 10 8 A(0.4) B(0,0) C(3.0) -10 -8 -6 -4:1-2 6 8 10 -2D(0
lesya [120]

Answer:

Option B

Step-by-step explanation:

It's clear from the graph attached,

ΔABC has been dilated and shifted downwards.

Length of segment AB = 2 units

Length of segment DE = 4 units

Scale factor by which the dilation has been done = \frac{\text{Dimension of the image triangle}}{\text{Dimension of the original triangle}}

Scale factor = \frac{DE}{AB}

                    = \frac{4}{2}

                    = 2

Therefore, triangle ABC is dilated by a scale factor of 2 about the origin.

Lets consider a point B(0, 0) from the given graph and analyze the transformations done.

If a point B(0, 0) is shifted to point E(0, -10) which follows the rule,

B(0, 0) → E(0 + h, 0 + k)

Here, 'h' and 'k' are the translations of the given point over x-axis and y-axis.

Therefore, (0 + h) = 0 ⇒ h = 0

0 + k = -10

k = -10

Hence, triangle ABC has been dilated by a scale factor of 2 centered at origin and followed by the translation (x, y - 10)

Option B is the correct option.
