In the given quadratic function, the domain is [-2, 0] and the range is y ≥ -4.

Quadratic function;

A polynomial function with one or more variables and a highest exponent of two is referred to as a quadratic function.

Given,

The graphic below displays the graph of a quadratic function with the vertex (-2, 4).

Here, we need to determine the function's domain and range.

We are aware that the domain of the quadratic function presented is all real values of x. And for the specified domain, the range is all real values of y. (real values values of x).

With reference to this description, we can see from the graph that the x axis' values range from -2 to 0.

The domain can therefore be written as [-2, 0].

Similar to the x axis, the y axis only accepts values greater than or equal to -4.

The range is therefore y ≥ -4 .

Answer:

Step-by-step explanation:

Both angles can add up to 180, so what I did was 7t-6 plus 5t+6=180. From there, I combined both positive 6 and negative 6 to which they cancel out. All that leaves is 7t+5t, which is 12t. Finally leaving 12t=180, so divided both sides by 12 to remove the 12 from 12t. 180/12=15. I think this is correct, but I am not sure. Please do check

Answer:  \(y=\frac{13}{2} x+3\)

Step-by-step explanation:

Remember the point-slope equation which is \(y-y_{1} = m(x-x_{1} )\)  where\((x_{1} , y_{1} )\) is your point and \(m\) is your slope.

Given that we substitute what you have:

\(y-(-10) =\frac{13}{2} (x - (-2))\)

Minus and minus give us positive:

\(y+10 =\frac{13}{2} (x +2)\)

Multiply slope into the parenthesis:

\(y+10= \frac{13}{2}x + \frac{13}{2}*2\\\)

Calculate it:

\(y+10= \frac{13}{2}x +13\)

Isolate the \(y\) by subtracting 10 from both sides:

\(y=\frac{13}{2} x + 13 -10\)

Your final equation is:

\(y=\frac{13}{2} x +3\)

The quantity of water left in the barrel is 5.175 gallons. The correct option is the second option 5.175 gallons

From the question, we are to determine how much water is left in the barrel

From the given information,

"The barrel is filled with 18 gallons of water"

and

"Ryan used 9.7 gallons to water his garden in June"

After this time,

The quantity of water that would be left in the barrel will be 18 gallons - 9.7 gallons

= 8.3 gallons

Then,

3 and one eighth gallons in July

3 and one eighth = 3 1/8 = 3.125 gallons

The quantity of water that would be left is 8.3 gallons - 3.125 gallons

= 5.175 gallons

Hence, the quantity of water left in the barrel is 5.175 gallons. The correct option is the second option 5.175 gallons

Answer:

Penguins can swim at a speed of 19.77 miles per hour.

Step-by-step explanation:

Since penguins can swim at speeds of up to 29 feet per second, to convert this speed to miles per hour, knowing that 1 mile is equal to 5280 feet, the following calculation must be performed:

1 hour = 60 minutes

1 minute = 60 seconds

1 hour = 60x60 seconds = 3,600 seconds

29 x 3,600 = feet per hour = 104,400

104,400 / 5,280 = miles per hour = 19.77

Thus, penguins can swim at a speed of 19.77 miles per hour.

The required value of x is 40 which is determined by the substitute that equals the vertical angles.

When two lines intersect at a location, vertical angles are generated. They are always equal to each other.

As per the given accompanying diagram, lines AB and CD intersect at point E.

Since ∠AED and ∠BEC are vertical angles then they are congruent, thus

⇒ ∠AED = ∠BEC

⇒ (x + 10) = 50

Subtract 10 from both sides of the above equation,

⇒ x + 10 - 10 = 50 - 10

⇒ x = 40

Thus, the required value of x is 40.

An arithmetic sequence with a common difference of −2 is 20,18,16,14,12..

Step-by-step explanation:

An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms is same. Here, the common difference is -2, which means that each term in the sequence is obtained by subtracting 2 from the previous term.

To find the arithmetic sequence with a common difference of -2, you can start with an first term and then subtract 2 successively to find the subsequent terms.

Let the initial term is 20. Subtracting 2 from 20, we get 18. Subtracting 2 from 18, we get 16. Continuing this pattern, we subtract 2 from each subsequent term to generate the sequence. The arithmetic sequence with a common difference of -2 starting from 20 is

20,18,16,14,12

In this sequence, each term is obtained by subtracting 2 from the previous term, resulting in a common difference of -2.

Option (C), t≈33 min

Step-by-step explanation:

Using Newton's law of cooling to answer the given question.

Given:

\(T_0=210 \ \textdegree F\\\\T_a=68 \ \textdegree F\\\\T(10)=200 \ \textdegree F\)

Find:

\(T(??)=180 \ \textdegree F\\\\\\\hrule\)

Newton's law of cooling is given as:

\(T(t)=T_a+(T_0-T_a)e^{-kt}\)

Substitute our know values into the equation.

\(\Longrightarrow T(t)=68+(210-68)e^{-kt}\\\\\\\Longrightarrow \boxed{T(t)=68+142e^{-kt}}\)

Now using the initial condition to solve for the value of "k."

\(T(t)=68+142e^{-kt}; \ T(10)=200\\\\\\\Longrightarrow 200=68+142e^{-k(10)}\\\\\\\Longrightarrow 132=142e^{-10k}\\\\\\\Longrightarrow \dfrac{66}{71} =e^{-10k}\\\\\\\Longrightarrow \ln\Big(\dfrac{66}{71}\Big) =-10k\\\\\\\Longrightarrow k=\dfrac{\ln\Big(\dfrac{66}{71}\Big)}{-10} \\\\\\\therefore k \approx 0.007303\)

Now we have the following function,

\(T(t)=68+142e^{-0.007303t}\)

Finding the value of "t" now.

\(\Longrightarrow 180=68+142e^{-0.007303t}\\\\\\\Longrightarrow 112=142e^{-0.007303t}\\\\\\\Longrightarrow \dfrac{56}{71}=e^{-0.007303t}\\\\\\\Longrightarrow \ln\Big(\dfrac{56}{71}\Big)=-0.007303t\\\\\\\Longrightarrow t=\dfrac{\ln\Big(\dfrac{56}{71}\Big)}{-0.007303} \\\\\\\therefore \boxed{\boxed{t \approx 33 \ min}}\)

Thus, option (C) is correct.

If total sales including tax are $2739.45 , the portion that is the tax amount is $155.06. So, correct option is C.

To find the portion that is the tax amount, we need to first determine the portion of the total sales that is the cost of the item before taxes. To do this, we can use the fact that the sales tax is 6%, which means that the total sales including tax is 106% of the cost before taxes.

Thus, we can set up the equation:

total sales including tax = cost before taxes + tax amount

Or, in terms of percentages:

106% cost before taxes = cost before taxes + tax amount

Simplifying this equation, we get:

0.06 cost before taxes = tax amount

Now we can substitute the given information into this equation. If total sales including tax are $2739.45, then the cost before taxes is:

cost before taxes = total sales including tax / 1.06

cost before taxes = $2584.39

Finally, we can calculate the tax amount:

tax amount = 0.06 * $2584.39

tax amount = $155.06

Therefore, the answer is option C, $155.06.

Westside Carpet charges more per square foot for the carpet

Since the Carpet City charges $5 per square foot for a type of carpet. They charge an additional $95 for installation.

we can write the linear function for Carpet City charges as:

y = 5x + 95

where x is the number of square foot

From the table:

rate for Westside Carpet = 3250/642 = $5.06 per carpet

The the linear function for Westside Carpet is y = 5.06x

Thus, Westside Carpet charges more because 5.06 is greater than 5.
