Find the domain and range. Write your answers as compound inequalities.

Answer:

The solution to this equation is (9t)^(12) / (4a)^(6).

Step-by-step explanation:

It is given that [(4a³t²)/(9at^6)]^-3 which is to be simplified and solved to get the final answer.

Now,

let us have a look at the equation and observe the powers given;

=> [(4a³t²)/(9at^6)]^-3

So, let us convert the powers using the rules;

=> [(4a²)/(9t^4)]^-3

Further, we will apply the rule known as product of powers and we get an equation that is;

=> (4a)^(-6) / (9t)^(-12)

Now, after reciprocating both the powers as per the rules we get;

=> (9t)^(12) / (4a)^(6)

Therefore, the solution to this equation is (9t)^(12) / (4a)^(6).

After rotating a parallelogram 270° counterclockwise points of D will be (2,7).

There are 4 types of translation they are, translation, rotation, and dilation.

We know when we rotate a shape 270° counter-clockwise the coordinates (x,y) becomes (y, -x) that is we switch x and y and make x negative.

Given a parallelogram with points C(-4,6), D(-7,2), E(6,6) and F(3,2).

Assuming point D when rotated 270° becomes D'.

∴ The points of D will switch which is (2,-7) and then we will make x negative.

The solution for the inequality | x | + 9 ≤ 7 is (option d) x ≤ -2 and x > -16

You can solve an inequality by: adding the same amount to each side; taking the same amount away from each side; multiplying or dividing each side by the same positive amount. The inequality symbol needs to be turned around if either side is multiplied or divided by a negative number. Therefore, the answer is x > 1.

Given,

The expression:   | x | + 9 ≤ 7

If | x | ≤ a ⇒ -a ≤ x ≤ a

Then,

-7 ≤ | x | + 9 ≤ 7

⇒ -7 - 9 ≤ x ≤ 7 - 9

⇒ -16 ≤ x ≤ -2

That is x ≤ -2 and x > -16.

In mathematics, a variable is a symbol and placeholder for any mathematical object. In particular, a variable may represent a number, a vector, a matrix, a function, the argument of a function, a set, or an element of a set

While multiplying two integer numbers, the rule is simple.

If both the integers have the same sign, then the result is positive.

If the integers have different signs, then the result is negative.

Answer:

[tex] \sf \: x=0.4[/tex]

Step-by-step explanation:

-0.5x-3.69=x-1.9-2.39

Step 1: Simplify both sides of the equation.

−0.5x−3.69=x−1.9−2.39

−0.5x+−3.69=x+−1.9+−2.39

−0.5x−3.69=(x)+(−1.9+−2.39)(Combine Like Terms)

−0.5x−3.69=x+−4.29

−0.5x−3.69=x−4.29

Step 2: Subtract x from both sides.

−0.5x−3.69−x=x−4.29−x

−1.5x−3.69=−4.29

Step 3: Add 3.69 to both sides.

−1.5x−3.69+3.69=−4.29+3.69

−1.5x=−0.6

Step 4: Divide both sides by -1.5.

−1.5x/−1.5 = −0.6/−1.5

x=0.4

The value of x will be 0.4.

In mathematics, an equation is a connection of two expressions that is expressed as an equality on all sides of the corresponding sign.  A statement that uses the equal sign to show that both of the expressions possess the same value is called an equation.

1) the mathematical model for given situation is f(t) = 2t + t, where t is the time in minutes

2) the amount of water in the pool after 50 minutes = 105 gallons

3) and the amount of time required to fill the pool =  12 hours 46 minutes

In this question,

a small pool hold 1500 gallons of water.

When there's is 5 gallons of water in the pool, the person decided

that not to stand outside and watch the pool fill.

This means, from the time he had decided, the amount of water in the pool = 5 gallons.

the water was filling the pool at a rate of 2.

Let t be the time in minutes.

So, the amount of water in the pool after 't' minutes would be,

f(t) = 2t + 5

We get an mathematical model for given situation,

f(t) = 2t + 5, where t is the time in minutes

We need to find the amount of water in the pool after 50 minutes

For t = 50 minutes

f(50) = 2(50) + 5

f(50) = 100 + 5

f(50) = 105 gallons

Also, we need to find the amount of time required to fill the pool.

1500 = 2t + 5

1495 = 2t

t = 747.5 minutes

t = 12 hours 46 minutes

Therefore, 1) the mathematical model for given situation is f(t) = 2t + t, where t is the time in minutes

2) the amount of water in the pool after 50 minutes = 105 gallons

An absolute value equation that has the given solution is  mathematically given as

I3 + xI - 7 = 0 where the solutions (or roots) are in X= 4 and X= -10

This is further explained below.

Generally, in this case, we want an absolute value equation that has the solutions x = 4 and x= -10.

A cheap way to do this is to look for a number N that:

N + 4 = -(N - 10)

then, isolating N we get:

2N = 6 + 10 = 6

N = 6/2 = 3

then

=N +4  

= 3 + 4

The equation to find the nth term of the sequence is aₙ = 4n - 17

The equation of the sequence can be represented as follows;

a₃ = - 5, a₄ = - 1, a₅ = 3, a₆ = 7, a₇ = 11

Therefore, let's find the equation of the nth term.

Using arithmetic formula,

aₙ = a + (n - 1)d

where

Therefore,

d = 11 - 7 = 4

Hence, let's find the first term using 7th term

11 = a + 6(d)

11 = a + 6(4)

11 - 24 = a

a = - 13

Therefore, the equation to find the nth term of the sequence is as follows:

Answer:

The values of x for the equation 5x² - 9x - 10 is x = 9 ± √(281) / 10.  

Step-by-step explanation:

In this question we need to solve the given equation that is 5x² - 9x - 10 to obtain the value of x using the complex solution method.

Now, the given equation is 5x² - 9x - 10 in which we need to apply the quadratic formula to find the solution;

So, the quadratic formula is => -b ± √(b² - 4ac) / 2a

Now, on comparing the equation 5x² - 9x - 10 we get the values;

a = 5

b = -9

c = -10

Further, on substituting the values given above in the quadratic formula to obtain the value of x.

=> -(-9) ± √((-9)² - 4(5×(-10)) / 2×5

=> 9 ± √(81 +200) / 10

=> 9 ± √(281) / 10

After simplifying the above equation we obtained the value of x that is;

=> x = 9 ± √(281) / 10

Now, the final values of x from the above condition are;

=> x = 9 + √(281) / 10  

and

=> x = 9 - √(281) / 10

It can be further represented in the decimal form;

=> x = 2.57630546...

and

=> x =  −0.77630546...

Thus, the values of x for the equation 5x² - 9x - 10 is x = 9 ± √(281) / 10.
