Hi again!


You need to do the same steps I used for the other one.

x² < 81

Find the critical points of the inequality

x² = 81

Then take square root

x = \pm \sqrt{81}

x = 9 or x = -9

Thus,


The answer is option B 9

Find the values of a through e that make these two relations inverses of each other. a = b = c = d = e = An image shows 2 tables
Sergio039 [100]

Answer:

a = -3.8

b = -2.6

c = 1.7

d = 4.4

e = 1.0

Step-by-step explanation:

In the figure attached, the tables are shown.

In an inverse relationship, any point (x,y) in one table is transformed to (y,x) in the other one. For example, in Table A coordinate (1, 2) is present, then in Table B (the inverse), coordinate (2, 1) must be present.

A bag contains marbles, two of which are blue. Hayley plays a game in which she randomly draws marbles out of the bag, one after
vivado [14]

Answer:

A)2/y

B)2/(y-1)

C)2/(y-2)

D)2/(y-3)

Step-by-step explanation:

Based on the information available :

Let the total number of marbles = y

Number of blue marbles = 2

Game ends when Hayley draws a blue marble.

NB: Marble is drawn without replacement

A.) P(game ends on first draw) = (number of blue marbles) / total number of marbles

P(game ends on first draw) = 2/y

B.) P(game ends on second draw) :

If game doesn't end on first draw, then no blue marble was drawn on the first pick

P(game ends on second draw) = 2/(y-1)

C.)P(game ends on third draw) = 2 / (y-2)

D.)P(game ends on fourth draw) = 2/(y-3)

There isn't enough information to solve the remaining problems

Based on a survey, 3 out of 8 households have a pet. Mike's neighborhood has 192 households.

The answer is c because if the survey says 3 out of 8 have one you divide 3/8 and multiply it by 192.

How do i write 12.009 in a word form?
tia_tia [17]
Your answer will be twelve and nine thousandths because in place value decimals are like tenths, hundredths, thousandths. In place value for regular numbers are ones, tens, hundreds and so on. So, when you have 12.009, you are going to separate the decimals with the numbers. Then, write down the number in words which would be twelve. Now, go to the decimal and write that down, which is 9 thousandths. Finally, combine the both of them to get: twelve and nine thousandths.

Hope this helps :) 
and good luck

Looking into the sky one night, Tori wondered how far into outer space she would get if she drove a car for 3.21 × 103 hours at
Westkost [7]

Answer:

         \large\boxed{\large\boxed{3\times 10^8meters}}

Explanation:

One of the applications of scientific notation is to make estimations rounding the whole part of the numbers, i.e. the digits before the decimal point, to the nearest integer, and adding the exponents of the powers of base 10.

Here, you must estimate this product of two numbers written is scientific notation:

          (3.21\times 10^3)(1.13\times 10^5)

Then, for an estimation you round 3.21 to 3 and 1.13 to 1, then multiply 3 × 1 = 3. That will be the coefficient of your new power of 10.

The power or exponent will be the sum of the powers of the numbers that are being multiplied, i.e. 3 + 5 = 8.

And the result is 3\times 10^8

The unit is meters, so you write your answer as: 3\times 10^8meters
