Ur answer will be marked as brainliest...
Julli [10]

Answer:

92.75 cm^2

Step-by-step explanation:

Area of triangle ADC

= (1/2)×4.5×12 = 27

Area of triangle ACB

=(1/2)×12×5 = 30

Find AB using pythagoras theorem on triangle ABC:

AB^2 = 5^2 + 12^2 = 25 + 144

AB^2 = 169

AB = 13cm

Area of triangle AGB

= (1/2)×13×5.5 = 35.75

Total area = sum of the areas of the 3 triangles found above

= 27 + 30 + 35.75 = 92.75 cm^2

Find a function whose graph is a parabola with vertex (7, 8) and that passes through the point. (6, −9).
lukranit [14]
Work backwards from vertex form. Vertex form of a quadratic equation/parabola is the following: 

f(x) = a(x - h)² + k, where (h, k) is the vertex. 

f(x) = a(x - 6)² - 9 

Now, plug in the point that you're given to SOLVE FOR A. Remember that f(x) is just another way of writing y. 

8 = a(1)² - 9 
8 = a - 9 
a = 17 

So, plug in a = 17 into the equation. 

<span>f(x) = 17(x - 6)² - 9 ←← your answer.


I hope my answer has come to your help. Thank you for posting your question here in Brainly.
