An exponential decay function has the form y = ka^x where a is between 0 and 1

In the first answer a > 1 so it is an exponential growth function

In the second answer (4/5)^-x = (5/4)^x so again a growth function

In the third answer (8/7)^-x = (7/8)^x so this is an exponential decay function

Can anybody help me with this?
Anika [276]

Answer:

Step-by-step explanation:

it's 12 by 10, 12 x 10 = 120. because it's a triangle, you divide 120 by 2.

120 / 2 = 60. therefore the area of the triangle is 60. I also don't know the unit im supposed to use. is it centimeters? inches? miles?

2. Which fraction is in its simplest form?<br> 2/4<br> 2/8<br> 2/6<br> 2/5
wariber [46]

Answer:

2/5

Step-by-step explanation:

2 / 4 could be divided by two in both sides.

2 ÷ 2 = 1

4 ÷ 2 = 2

2/4 = 1/2

Same goes for 2/8 and 2/6

2 ÷ 2 = 1

8 ÷ 2 = 4

2/8 = 1/4

2 ÷ 2 = 1

6 ÷ 2 = 3

2/6 = 1/3

2/5 however, could not be divided by two on both sides because there is 5 and it is not a factor of 2. So it is in its simplest form

At the movies, a couple bought 2 medium drinks and a large popcorn for $13.85. At the same theater, a family bought 3 medium dri
yawa3891 [41]

Answer:

cost of one medium drink = $3.80

cost of one large popcorn = $6.25

Step-by-step explanation:

Let D = cost of one medium drink

Let P = cost of one large popcorn

If a couple bought 2 medium drinks and a large popcorn for $13.85:

⇒ 2D + P = 13.85

If a family bought 3 medium drinks and 2 large popcorn for a total of $23.90:

⇒ 3D + 2P = 23.90

Rewrite 2D + P = 13.85 to make P the subject:

⇒ P = 13.85 - 2D

Substitute into 3D + 2P = 23.90 and solve for D:

⇒ 3D + 2(13.85 - 2D) = 23.90

⇒ 3D + 27.7 - 4D = 23.90

⇒ D = 3.8

Substitute found value of D into P = 13.85 - 2D to find P:

⇒ P = 13.85 - (2 x 3.8) = 6.25

Therefore,

cost of one medium drink = $3.80

cost of one large popcorn = $6.25
