Answer:  The estimate is closest to the distance d is 4.2 miles


Step-by-step explanation:

In the given image, we can see that there is a right triangle, in which d is the side opposite to the right angle (largest angle in the triangle) which means its the longest side of the triangle.

[Since side opposite to the larger angle is larger]

Therefore, by Pythagoras Theorem we have

d^2=(3.6)^2+(2.2)^2\\\Rightarrow\ d^2=12.96+4.84\\\Rightarrow\ d^2=17.8\\\Rightarrow\ d=\sqrt{17.8}\\\Rightarrow\ d=4.2190\approx4.2

The estimate is closest to the distance d is 4.2 miles.

The number of teams who entered in a 3-on-3 charity basketball tournament can be modeled by function T, where x is the number of
Svetradugi [14.3K]

Answer:

<u>Option A:</u>

R(x)=20x^2+300x+1080

Explanation:

The revenue, R(x) is the product of the number of teams who entered the tournament, T(x), times the entry fee paid by each team, F(x); then you can write:

  • R(x)=T(x)\times F(x)

Thus you must multiply the two functions (polynomials):

  • R(x)=(4x+24)\times (5x+45)

Use distributive property:

R(x)=(4x+24)\times (5x+45)=(4x)(5x)+(4x)(45)+(24)(5x)+(24)(45)

Simplify:

R(x)=(4x)(5x)+(4x)(45)+(24)(5x)+(24)(45)=20x^2+180x+120x+1080

Add like terms:

R(x)=20x^2+180x+120x+1080=20x^2+300x+1080

Whixh statement is true about the graphs of the functions shown below?
Nata [24]

Answer:

Step-by-step explanation:

Since G(0) = g(0) = 20, the parabolic graphs of these functions share a y-intercept:  (0, 20).

Completing the square puts these equations into vertex form, which simplifies comparisons of the graphs:

G(x) = 2x^2 - 12x + 20 becomes

          2(x^2 - 6x + 9 - 9) + 20, or

          2(x - 3)^2 - 18 + 20, or 2(x - 3)^2 + 2.  Comparing this result to

          a(x - h)^2 + k, we see that the vertex is located at (3, 2).

Going through the same process for g(x) 2x^2+12x+20, we get:

g(x) = 2(x + 3)^2 + 2, whose vertex is at (-3, 2).

Next time, please include ALL info pertaining to your question, including the set of possible answer choices.  Thank you.

Sandra uses her office fax machine to send fax at the rate of $0.10 per page. She decides to rent a fax machine for $80 a year.
Maksim231197 [3]
Part A: 
 First we define the variable to be used for the problem:
 x: the number of pages that Sandra should fax
 The inequality for rent is:
 0.06x <= 80
 Note that the price will be less than using the fax from the office, since for the same number of pages, we have:
 y = 0.10x
 Answer:
 
an inequality that can be used to calculate the number of pages that Sandra should fax in a year is:
 
0.06x <= 80

 Part B:
 0.06x <= 80
 From here we clear x:
 x <= 80 / 0.06
 x <= 1333.33333
 Nearest whole number
 x <= 1333
 Sandra can use the leased fax for 1333 pages and the cost will be:
 1333 * 0.06 = 79.98 $
 Using the office fax the cost will be:
 1333 * 0.1 = 133.3 $
  Answer:
 
By renting the sara machine, you save:
 
133.3-79.98 = 53.32 $
