1 - yes 100 and 75 are both collinear both are the same line.

2 - She can conclude that there both similar because the both go the same direction and both same shape.

3 - AB would equal 150 because the other one was 100 and the other angle was 25 down. So AB would equal 150.

Hope I helped

The length of rectangle is represented by x and the width by y. The square of the diagonal of the rectangle is equal to the sum
maksim [4K]
To solve this problem you must apply the proccedure shown below:

 1- You have the following information given in the problem above:

 - <span>The square of the diagonal of the rectangle is equal to the sum of the squares of the length and the width.
 - The length is 25 meters and the diagonal is 45 meters.

 2- Therefore, you have:

 x: diagonal of the rectangle.

 x^2=l^2+w^2

 3- You have:

 w^2+l^2-x^2=0
 w^2+(25)^2-(45)^2=0
 w^2-1400=0
 w=37.41

 The answer is: </span>w^2-1400=0

I really need help pls helppp meee
zhenek [66]

Answer:

2.50t + 350 = 3t + 225

Step-by-step explanation:

Let t represent the number of tickets that each class needs to sell so that the total amount raised is the same for both classes.

One class is selling tickets for $2.50 each and has already raised $350. This means that the total amount that would be raised from selling t tickets is

2.5t + 350

The other class is selling tickets for $3.00 each and has already raised $225. This means that the total amount that would be raised from selling t tickets is

3t + 225

Therefore, for the total costs to be the same, the number of tickets would be

2.5t + 350 = 3t + 225

The function f(x) = –x2 + 20x – 75 models the profit from one customer, in dollars, a shop makes for printing photos, where x is
trasher [3.6K]
The function is graphed as shown below

Part A:

We use the formula - \frac{b}{2a} to find the vertex of the function. A quadratic function of the form of a x^{2} +bx+c and equating this form to the given function - x^{2} +20x-75, we have
b=20 and a=-1.

Substituting a and b into the vertex formula, we have
x=- \frac{20}{2(-1)}=10, as shown in the graph

This calculation means that the highest profit is achieved when the number of photo printed equals to ten photos

Part B:

We can find solution to this equation by factorising

- x^{2} +20x-75=0
-( x^{2} -20x+75)=0
x^{2} -20x+75=0
(x-5)(x-15)=0
x=5 and x=15, as shown in the graph

The two values means that the company makes no profit when they either produce 5 or 15 photos
