Determine if the following relation represents a function or not.
artcher [175]

Answer:

It is a function.

Step-by-step explanation:

Functions are relations in which one domain value is assigned to exactly one range value. The x-value must not repeat in the relation set for it to be a function.

{(2,3), (4,3), (6,3), (5,9), (3,9)}

There are no repeating x-values given.

The relation should be a function.

Hope this helps.

Use the grid to create a model to solve the percent problem.
Delicious77 [7]
For this case we can make the following rule of three:
 21 ------> 70%
 x --------> 100%
 Clearing x we have:
 x = (100/70) * (21)
 Rewriting we have:
 x = (10/7) * (21)
 x = 30
 Thus,
 21 is 70% of 30
 Answer:
 
21 is 70% of 30

The population of Brazil was 162,300,000 in 1995. It was growing at a rate of about 2% per decade. Predict the population, to th
stiv31 [10]

Answer:

The population is 168,900,000 to the nearest hundred thousand

Step-by-step explanation:

In this question, we are tasked with calculating the population of Brazil given its population in 1995 and her growth rate per decade.

Mathematically, we use an exponential function to calculate this population.

This can be written as P = I(1 + r)^n

where P is the population in 2015 which we are looking for,

I is the initial population which is 162,300,000

r is the rate of increase per decade given as 2% = 2/100 = 0.02,

n is the number of times between the years we are expecting this growth. The difference between the years 2015 and 1995 is 20 years which signifies 2 decades(1 decade is 10 years). Thus our n is 2

We plug these values into the equation above;

P = 162,300,000(1+0.02)^2

P = 162,300,000(1.02)^2

P = 168,856,920 which is 168,900,000 to the nearest hundred thousand

1. Sarah applies the pearl guitar fret markers to her fret board as shown. Each fret marker is in the shape of a parallelogram.
Flura [38]

Answer:

315

Step-by-step explanation:

We are told in the question that each fret marker is in the shape of a parallelogram

The area of a parallelogram is given as

Base × Height.

Each of the bottoms of the fret markers has the following values

Base = 52.5mm

Height =6 mm

The area of each of the bottom fret markers

= Base × Height

= 52.5 × 6

= 315

Therefore, the area of each of the bottom fret markers without unit is 315
