Answer:

mass on day 1:  3

mass on day 2: 9

mass on day 3: 27

Step-by-step explanation:

using this equation, y = 3^x, you can plug in 1, 2, and 3 for 'x' to get the value of 'y' (which represents the mass on specific days)

3^1 = 3

3^2 = 9

3^3 = 27

Answer:

B, 4

Step-by-step explanation:

To do this you can use the Pathagaryos thereom a^2+b^2=c^2

So we have (x-2)^2+x^2=20

We can expand (x-2)^2 and get

x^2-4x+4

so we have x^2 -4x +4 + x^2=20

We can combine like terms and subtract 20 from both sides to get

2x^2-4x-16=0

We can factor this and get (2x+4)(x-4)

which means that x=4 and -2

Obviously the length can't be a negative and so we reject x= -2 and we get x=4

We can double check it and see that

(4-2)^2+4^2=20

and it does

Answer:

m = 7, b = -2

Step-by-step explanation:

The equation y = 7x - 2 is written in y = mx + b, also known as slope intercept.

In slope-intercept, m is the slope and b is the y-intercept.

m = coefficient of x

b = constant

Similarly,

m = 7

b = -2

Hence, m = 7 and b = -2.

Answer:

Assuming you want to simplify the expression, it can be shortened to:

-k² - 2k

Step-by-step explanation:

What you need to do here is called grouping like terms.  Like terms can be described as terms that have the same factors.  In this case, the factors we're looking at are k and k²:

Given:

k - 3k² -3k + 2k²

We'll rearrange to group like expressions:

= -3k² + 2k² + k -3k

Pull out common factors:

= (-3 + 2)k² + (1 - 3)k

And simplify:

= -k² - 2k

Answer:

The last one!

Step-by-step explanation:

Domain is always x. It is not a function because the y doesnt have a pattern.

Answer:

x = 0, y = 0

or

(0, 0)

Step-by-step explanation:

-24x - 36y = 0

divide the equation by 4

-8x - 9y = 0

-6x - 9y = 0

multiply the second equation by -1

6x + 9y = 0

add them together

-8x - 9y = 0

6x + 9y = 0

-2x = 0

x = 0

substitute into the second equation

-8 * 0 - 9y = 0

-9y = 0

y = 0

Answer:

the answer is 9/2

Step-by-step explanation:

So you have (x+3)/6=5/4

Cross multiply and it will turn to this

4(x+3)=6×5 which is 30

= 4x+12=30

4x=30-12

4x=18

Divide both sides by 4 to make x subject of the formula

then your answer is 9/2

Answer:

This is from least to greatest.

-0.89, 0.4, 1/2, 9/8, (-2)

Step-by-step explanation:

-0.89 is negative so it is the least because the other numbers are positive.

0.4 is next because 0.4 is smaller than 0.5 because 1/2 = 0.5

Then 1/2 because 9/8 is more than 1/2 of 8 which would be 4, but 9/8 is bigger than 4/8.

Finally the biggest number is (-2) Because the absolute value of -2 is 2, and 2 is a whole number, which is bigger than the decimals and fractions.

And of course 9/8 is equal to 1 1/8 but 2 is bigger than 1 1/8

Answer:

10 units; C

Step-by-step explanation:

To get this, we will

use the distance formula

That is:

D =√( (x2-x1)^2 + (y2-y1)^2

D = √(-5-3)^2 + (-2-4)^2

D = √(64+36)

D = √100

D = 10 units

Answer:

92.30

Step-by-step explanation:

The area of the banner is the amount of space on it

The approximate cost of the banner is $92.30

The dimension of the banner is given as:

Length = 9 feet

Width = 12 feet

Diagonal = 19 feet

The figure of the banner is not given.

However, the area of the banner from the complete question is 83.90

Given that the unit cost is $1.10, the total cost would be:

Total = 1.10 * 83.90

Evaluate the product

Total = 92.29

Approximate

Total = 92.30

Hence, the approximate cost of the banner is $92.30

Answer:

The asteroid will not take out Lois' penthouse.

Step-by-step explanation:

Since the distance between Clark and the base of Lois' building is x = 75 feet and the asteroid is at an angle of elevation of Ф = 62°. These two components form a right-angled triangle with opposite side h which is the height of the asteroid above the ground.

So, by trigonometric ratios,

tanФ = h/x

h = xtanФ

h = 75 ft × tan62°

h = 75 ft × 1.8807

h = 141.1 feet

Since h = height of asteroid above the ground = 141.1 feet is greater than height of the penthouse above the ground = 100 feet, the asteroid will not take out Lois' penthouse.
