Answer:

<u>Domain:</u> [1,∞), {x|x≥1}

<u>Range:</u> (−∞,∞), {y|y∈ℝ}

Step-by-step explanation:

The equation of that line is y^{2}=x-1, and the domain and range of y^{2}=x-1 is:

<u>Domain:</u> [1,∞), {x|x≥1}

<u>Range:</u> (−∞,∞), {y|y∈ℝ}

Hope this helps! :)

<u>Answer</u>


A) 7.3 in.



Explanation

The area of a triangle = 1/2 ×base length × height

In the question given, base length = height = x

Area = 27 in²

1/2 × x × x =27

1/2×x²=27

x² = 54

x = √54

= 7.3485 in²

Diana is painting statues. She has \dfrac{7}{8} 8 7 ​ start fraction, 7, divided by, 8, end fraction of a liter of paint remaini
anzhelika [568]

Answer:

Number of statues that can be painted are 17

Step-by-step explanation:

Initially Diana has \frac{7}{8} liters of paint remaining.

Every statue requires \frac{1}{20} liters of paint for painting.

We have to find how many statues we will be able to paint with this remaining paint.

To get the number of statues,

Number of statues = \frac{Paint remaining}{Paint required for 1 statue}

number of statues = \frac{\frac{7}{8} }{\frac{1}{20} }

                               = \frac{35}{2} = 17.5

Since the number of statues is not an integer the maximum number of statues that can be painted are 17.

Answer:

(2) 2,640 ft

Step-by-step explanation:

I'm going to assume that in this question, you are walking 1 full circle around the reservoir. That would mean you need to calculate the circumference of the circular reservoir.

The circumference formula is:

C = ⫪d

C stands for Circumference

d stands for diameter

I will use 22/7 instead of pi, so the formula looks more like this:

C = (22/7)(d)

The diameter is 840 feet, so we will substitute the variable d with 840:

C = (22/7)(840)

You can plug this part into the calculator, but by hand, it'll look something like this:

(22/7)*840 = (22*840)/7

18,480/7 = 2.640

Hope it helps (●'◡'●)

Kayla buys two pairs of jeans for j dollars each and one shirt for 15 dollars. she has 60 dollars to spend. The equation 2j+ 15-
weeeeeb [17]

Kayla buys two pairs of jeans for j dollars each and one shirt for 15 dollars. The cost of one pair of jeans is $22.5  (twenty-two dollars and fifty cents)

From the given information

  • Let the cost of two pairs of jeans be 2j
  • The cost of 1 shirt = 15
  • Total amount to spent = $60

∴

The equation is said to be expressed as:

  • 2j + 15 - 60 = 0

Collect like terms

  • 2j = 60 - 15
  • 2j = 45

Divide both sides by 2

  • \mathbf{\dfrac{2j}{2}= \dfrac{45}{2}}
  • j = 22.5

Therefore, we can conclude that the cost of one pair of jeans is  $22.5  (twenty-two dollars and fifty cents).
