The function in vertex form is f(x) = (x-4)2-11
the y-intercept of the function is (0,5)
the function crosses the x-axis twice
Answer:
12 miles by 8 miles
Step-by-step explanation:
Let length be represented by x
Since width is 4 miles less than the length, therefore, the width will be (x-4) miles
Area=Length*Width
Area=x(x-4)=
Area is given hence
To write the above equation as a quadratic equation
By factorization, we find two numbers whose sum is -4 and product is -96, these are 8 and -12. Therefore, taking these two numbers back to our equation
(x+8)(x-12)=0
Therefore, x=-8 or 12
Equally, using quadratic formula of
for equation and in our case a=1, b=-4 and c=-96
x=-8 or 12
Since length can't be negative, hence x=12
The length is 12 miles
Width=12-4=8 miles
Dimensions: 12 miles by 8 miles
14 times 6 is 84, sorry if I didn’t understand your question
X/sin 42 = 43/sin 87
x = (43 * sin 42)/(sin 87)
x = 28.812
Answer: 28.8
