Answer:

a; exponential growth

b; linear decrease

c; exponential decay

d; linear increase

e;exponential growth

f; linear decrease

g;exponential decay

h; exponential decay

Step-by-step explanation:

perecents(like the 20% on one) are automatically exponential

then you look at context words like increase which tells you growth or depreciates which tells you decrease

numbers (like $40,000 on one) signify a linear function and you do the same with the context clues

with equations:

y=mx+b equations are linear growth

y=mx-b equations are linear decrease

y=c(0<x<1) are exponential decay

y=c(x>1) are exponential growth

hope this helps!!

west deposited $15,000 in a savings account earning 2.5% simple interest what was the total interest earned at the end od 8 year

Lelechka [254]

2.5% of 15,00$ would be 375$. Assuming the "simple interest" is yearly, you would multiply 375 by 8, which is 3000$ :P (Another way to solve this would be to multiply the 2.5 by 8, which would be 20. and 20% of 15,000$ would also be 3,000$)

Answer: 21.69 g

Step-by-step explanation:

Find the amount of compound produced when 300 mg of catalyst is added

Given:

Equation: A = 0.06c + 3.16

c = 300 mg

Substituting c = 300 into the equation and solving for A

A = 0.06 * 300 +3.69

A = 18 + 3.69

A = 21.69

Therefore 21.69 g of compound will be produced

Given: CD is a perpendicular bisector of AB . Prove: Any point on CD is equidistant from the endpoints of AB . Match each statem

Sunny_sXe [5.5K]

Answer:

The two triangles are congruent, so any point on CD will be equidistant from endpoints of AB.

Step-by-step explanation:

Let the consider the figure as per the attached image:

AB be a line whose perpendicular bisector line is CD.

CD divides the line AB in two equal line segments making an angle of $90^\circ$ on both the sides as shown in the attached figure.

Let a point on CD be E.

Here, two triangles are formed:

$\triangle AED\ and \ \triangle BED.$

Side ED is common between the two triangles.

Also, Side ED is perpendicular bisector:

$\angle EDA = \angle EDB =90^\circ$

And Sides AD = DB

According to SAS congruence (i.e. Two sides are equal and angle between them is equal):

$\triangle ADE \cong \triangle BDE$

And as per the properties of congruent triangles, all the sides are equal.

$\Rightarrow EA = EB$

EA and EB is the distance of point E on line CD from the endpoints of line AB.

Hence proved that Any point on CD is equidistant from the endpoints of AB .
