I am assuming you meant to write f(x) = 3^x -2

f(3) = 3^3 - 2 <=>

f(3) = 27 - 2 <=>

f(3) = 25

Answer:

x = 82°

y = 59°

z = 39°

Step-by-step explanation:

∠x = 1/2(134° + 30°) = 82°

∠z = 180° - 59° - 82° = 39°

arc DF = 2(39°) = 78°

arc DB + arc DF = 134° + 78° = 212°

draw a diameter down from point B to the opposite side of the circle, call that point P:

arc BDP = 180°

(arc BDF) 212° - 180° = 32° (arc PF)

∠PBG = 1/2(32°) = 16°

∠DEB = 1/2(134°) = 67°

∠DBE = 180° - 59° - 67° = 54°

(∠DBE) 54° - (∠z) 39° + (∠PBG) 16° = (∠PBE) 31°

y = 90°- 31° = 59°

Module 04.03 Exponential Functions and Models: Essential Questions:
azamat
1. Exponents are the repeated multiplication of a number. It is represented by the formula of a^n where a is the number to be repeated and n is the number of times the number is being multiplies by itself. Also include the sign of the number, no matter how it is multiplied, it is still important. For instance you have 4(4), you have 4 as the repeated number. You can see that it is multiplied by itself by two times. So you have (-4)^2.

2. Graphs and tables are the key features in finding a model between two quantities. If he data values, after plotting it into a graph, produces a straight line, then you will have a direct relationship between the two and sometimes you can get an equation of the line. Sometimes it will give you a curved line. That is why it is important to graph the values of the table to better understand the relationship between two variables.

JUST 1 PLEASEEEEEEEEEE AND HOW DO YOU KNOW!!!!! PLEASEEEEEEEEEEEEE HELLLPPPPPPPPPPPP MEEEEEEEEEEEEEE
Lemur [1.5K]

Answer:

I can't see three but I'll answer the first two.

Step-by-step explanation:

Number one: The first, third, and fifth options are correct,

Number two: A is correct because if you divide 3/4 you get 0.75. Check by multiplying 0.75 for one by 4 and you get three dollars.

So for three, one pound of pears costs two dollars. That is consistent with the graphs. Pick the answer that states that the best.

How do I do 21? (Will mark brainlest for explaining)
Maslowich
Let's say the number is x
75%of x is 15
75%x=15
0.75x=15
x=15/0.75
x=20

or you can say 3/4x=15
x=15*4/3
x=20
