Answer:

It's the first one, the one that has the triangles.

Step-by-step explanation:

They only have a difference of 2. Multiplying the small one by 2 equals the larger one. Doing the opposite and dividing 2 by the larger one gives you thee small triangle. they both have the same angles which makes them similar.

food express is having a special promotion in which customers can win a free gallon of milk if they're receipt has a star on it.
jeka94
We know here 147 out of 156 customers are not won so far
Probability of not winning=147/156
P not wining=0.94
so probability for winning is 1-P not wining
1-0.94= 0.057

if u want an answer is numerator and denominator so u just find 1-147/156<span />

a road follows the shape of a parabola f(x)=3x2– 24x + 39. A road that follows the function g(x) = 3x – 15 must cross the stream
Nonamiya [84]

the coordinates where the bridges must be built is (3,-6) and (6,3) .

<u>Step-by-step explanation:</u>

Here we have , a road follows the shape of a parabola f(x)=3x2– 24x + 39. A road that follows the function g(x) = 3x – 15 must cross the stream at point A and then again at point B. Bridges must be built at those points.We need to find Identify the coordinates where the bridges must be built. Let's find out:

Basically we need to find values of x for which f(x) = g(x) :

⇒ f(x)-g(x)=0

⇒ 3x^2- 24x + 39-(3x - 15 ) =0

⇒ 3x^2- 24x + 39-3x + 15  =0

⇒ 3x^2- 27x + 54  =0

⇒ x^2- 9x + 18  =0

⇒ x^2- 6x-3x + 18  =0

⇒ x(x- 6)-3(x - 6)  =0

⇒ (x-3)(x- 6)  =0

⇒ x=3 , x=6

Value of g(x) at x = 3 : y=3x -15 = 3(3)-15 = -6

Value of g(x) at x = 6 : y=3x -15 = 3(6)-15 = 3

Therefore , the coordinates where the bridges must be built is (3,-6) and (6,3) .
