Answer:

the answer is D. 38.15

Step-by-step explanation:

the lunch meat is 5.50 for 5lbs. She only needs 2 1/2 lbs so you would just divide 5.50 by 2 (because 2 1/2 is half of 5). for the soft drinks, it is 9.99 for 3 so each one 3.33 (divide 9.99 by 3). When you add two more to get five cases in total, you get 16.65 (because 9.99 plus 3.33 plus 3.33 = 16.65). the lunch meat is 4.25 each and you need 3 so you just multiply 4.25 by 3. the snack mix bags are 2 for 1.50 each. that means that two is 3.00. you need four so you just do 3.00+3.00 which equals 6. when you add these totals together, you get 38.15

Which polynomial is a quadratic trinomial?
il63 [147K]
<h3>Answer: Choice C</h3>

The largest exponent here is 4, so that makes it a quartic.

There are 3 terms, so we have a trinomial. Each term is separated by either a plus or a minus.

Choice A shows a quartic polynomial. Choice B is a cubic polynomial. Choice d is a quadratic trinomial.

Free_Kalibri [48]

The equation for the situation is y=200(\frac{2}{3})^{x}

It will take around 9 years for her to have around 5 sheep

Step-by-step explanation:

The exponential decay growth/decay equation is y=a(b)^{x} , where

  • a is the initial value
  • b is the growth/decay factor
  • If b > 1, then it is a growth factor
  • If 0 < b < 1, then it is a decay factor

Erica is a sheep farmer. She is having a problem with wolves attacking the flock. She starts with an initial 200 sheep and notices that the population is two-thirds of the previous year

∵ The population is decreased

∴ The equation is decay

∵ The population is two-thirds of the previous year

∴ The decay factor is \frac{2}{3}

∵ She starts with an initial 200 sheep

∴ the initial value is 200

∵ The decay equation is y=a(b)^{x} , where y represent the

   population in x years

∵ a = 200

∵ b = \frac{2}{3}

∴ y=200(\frac{2}{3})^{x}

The equation for the situation is y=200(\frac{2}{3})^{x}

∵ The population after x years is around 5 sheep

- Substitute y by 5 to find x

∵ 5=200(\frac{2}{3})^{x}

- Divide both sides by 200

∴ 0.025=(\frac{2}{3})^{x}

- Insert ㏒ for both sides

∴ log(0.025)=log(\frac{2}{3})^{x}

∴ log(0.025)=xlog(\frac{2}{3})

- Divide both sides by log(\frac{2}{3})

∴ 9.098 = x

∴ x is around 9 years

It will take around 9 years for her to have around 5 sheep

Solve: 2 + = 2. Give solutions in interval [0, 2)
Dovator [93]
\because\cos 2x+\sin x=\sin 2x\because\sin 2x=2\sin xcosx\because\cos 2x=\cos ^2x-\sin ^2x

→ Substitute cos 2x and sin 2x by their expressions

\therefore\cos ^2x-\sin ^2+\sin x=2\sin x\cos x

→ Subtract both sides by sin x

\cos ^2x-\sin ^2x=2\sin xcosx-\sin x

→ Take sin x as a common factor in the right side

\therefore\cos ^2x-\sin ^2x=\sin x(2\cos x-1)

From the graph, the equation has 4 solutions, the intersection points between the 2 graphs
