D.) 7 units
WILL MARK BRAINLIEST!!!!

Answers

Answer: The correct answer is 29 units

Step-by-step explanation: Can i Get the brainliest answer?

The distance between points (8, 3) and (3, 1) on the coordinate plane is √29 units.

Given that, the distance between points (8, 3) and (3, 1) on the coordinate plane.

What is distance formula?

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On 2D plane the distance between two points (x1, y1) and (x2, y2) is Distance = √[(x2-x1)²+(y2-y1)²].

Now,

Put, (x1, y1)=(8,3) and (x2, y2)=(3,1) in distance formula, that is

Distance = √[(1-3)²+(3-8)²]

= √(4+25)

= √29 units

Therefore, the distance between points (8, 3) and (3, 1) on the coordinate plane is √29 units.

1) A city has a population of 21,517 based on a census taken in 1998. If the
population is expected to grow by 11% annually, what will the population
be in the year 2030? *
A None of these
B 606,900
C 492,573
D 517

Answers

Answer:

B, 606,900

Step-by-step explanation:

First you'll need to calculate the percentage growth after 32(2030 - 1998) years. to do this you'll need to find 1.11^32 or 28.205, 1.11 being the percentage growth per year and 32 being the number of years passed. then 21,517*28.205 = 606,899.8 which can be rounded to 606,900.

Solve using the order of operations. (9+9+72)-4+9

PLZ ANSWER PLZ HURRY​

Answers

Answer:

95

Step-by-step explanation:

The order of operations is PEMDAS

Equations in PARENTHESES come first

Numbers with EXPONENTS come second

MULTIPLICATION/DIVISION problems come next (depending on which comes first in the equation

ADDITION/SUBTRACTION comes last (again, depending on which comes first in the equation)

So we do (9+9+72) first

So that equals 90

And then we subtract 4 from 90

90 - 4 = 86

Then we add 9 to 86

86 + 9 = 95
