[tex] \frac{3}{10} \\ \\ or \: in \: alternate \: \: form \\ \\ 0.3[/tex]

Answer:

B)29

Step-by-step explanation:

[tex] {x}^{2} = {21}^{2} + {20}^{2} [/tex]

[tex] {x}^{2} = 441 + 400[/tex]

[tex] {x}^{2} = 841[/tex]

[tex]x = \sqrt{841} [/tex]

[tex]x = 29[/tex]

Answer:

B

Step-by-step explanation:

Using Pythagoras' identity

The square on the hypotenuse is equal to the sum of the squares on the two legs, that is

x² = 21² + 20 ² = 441 + 400 = 841 ( take square root of both sides )

x = [tex]\sqrt{841}[/tex] = 29 → B

Answer: 1. it doesnt since the velocity is so high, it will land in the water.

2. the ball goes about 500 feet in the air.

3. the ball reaches its max height when it starts to go down

4. the ball is at 250 since it takes 8.6 seconds for it to reach 500 feet

Step-by-step explanation:

Answer:

x = 6+3y

y = y (any number)

the rest should follow the same steps

Step-by-step explanation:

2x-6y=12 -> divide both sides by 2 (GCF)

x-3y = 6 -> solve for x, because it has 1 as its coefficient, or the lowest coefficent

x = 6+3y

-5x+15y=-30 -> divide both sides by 5

-1x+3y=-6 -> plug in x from previous equation

-(6+3y) + 3y = -6

-6-3y+3y = -6

y = y

[tex] \frac{1}{3} {x}^{2} = - 3 \\ = > {x}^{2} = - 3 \times 3 \\ = > {x}^{2} = - 9 \\ = > {x} = \sqrt{ - 9} \\ = > x = ±3[/tex]

Answer:

C) x = ±3

Hope you could get an idea from here.

Doubt clarification - use comment section.

Answer:

No solution

Step-by-step explanation:

Since both x's are positive, there's no way to put to x on either side, because when you transfer sides, you add/subtract the opposite, so there can't be a value for x

Answer:

  A.  {-1, 2, 7}

Step-by-step explanation:

For a set of ordered pairs, the domain is the set of first-numbers (x). The range is the set of second numbers (y, or g(x)).

The first step here is to find the g(x) values for each of the listed x-values.

The attachment shows a table.

Often, we like to list the domain and/or range values in numerical order, eliminating any duplicates. That is, the set of range values {2, -1, -1, 7} would be listed as ...

  {-1, 2, 7} . . . . . . matches choice A

_____

You find the g(x) values by substituting for x and doing the arithmetic.

  g(-2) = (-2)² -2 = 4 -2 = 2, for example

I think correct answer is-3

Answer: The Third option

Step-by-step explanation:

1/36a^4b^10

Hope this is right!

The expression equivalent to the given expression is 1/36a⁴b¹⁰. Therefore, option C is the correct answer.

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

The given expression is ((2a⁻³b⁴)²/(3a⁵b)⁻²)⁻¹.

Now, ((2²a⁻⁶b⁸)/(3⁻²a⁻¹⁰b⁻²))⁻¹

= (2⁻²a⁶b⁻⁸)/(3²a¹⁰b²)

= (a⁶)/(3²2²a¹⁰b²b⁸)

= 1/36a⁴b¹⁰

Therefore, option C is the correct answer.

Answer:

length = 5x + 6

Step-by-step explanation:

35x + 42 = 7*L    since area of a rectangle is length * width

(35x + 42) divide by 7  =  7L divide by 7

5x +6 = y

Hi!

To calculate the rate of change between days 4 and 6, we simply take those points, (4, 1503) and (6, 2196) and use the equation in the picture below:

Now, when we plug it in the equation, it looks like this:

[tex]\frac{2196-1503}{6-4} = \frac{693}{2} = 346.5[/tex]

Therefore, your answer is 346.5 or, rounded, 347.

Meaning, your answer is C

Answer:

1   7/16

Step-by-step explanation:

If c = 7, then

12 - 2c

= 12 - 2(7)

= 12 - 14

= -2

c - 5

= (7) - 5

= 2

=》+2 > -2.

So, c - 5 has greater value than 12 - 2c, if c = 7.
