Answer:
f(x) = x² - 6x + 14
Step-by-step explanation:
Standard form is ax² + bx + c = 0 or f(x) = ax² + bx + c
So we are going to expand the equation and combine like terms:
f(x) = (x - 3)² + 5
f(x) = x² - 3x - 3x + 9 + 5
f(x) = x² - 6x + 9 + 5
f(x) = x² - 6x + 14
the value of the dimes is 10(21 - 5)
hope this helps
Answer:
y = x^2+3x-4 y=3x+5
(3, 14)
Step-by-step explanation:
hope this helps and have a nice day!! :)
And also you should try to use Desmos calculator it really helps with these problem/ equations!! you just have to put y = x^2+3x-4 then press enter and on the second one you put y=3x+5 and then it shows you a graph and plus the answer!! :))
Given :
<span>Triangle fgh is inscribed in circle o
</span>
oh = 6 = radius of the circle
<span>∵ fh is congruent to og
</span>
<span>∴ fh = og = radius og the circle = 6
</span>
<span>∵ of = radius of the circle = 6
</span>
<span>∴ oh = fh = of = radius of the circle = 6
</span>
∴ Δ foh is Equilateral Triangle
<span> </span>∴∠ foh = 60° ⇒⇒⇒ property of <span>the equilateral Triangle
</span>
∵ total area of the circle = π r² and total central angle of the circle = 360°
∴ Area of sector foh = (60°/360°) * π r²
∴ Area of sector foh = (60°/360°) * π * 6² ≈ 18.85
The answer is:
<span>the area of the sector formed by angle foh
= 18.85</span>
