<span>The axis of symmetry of the quadratic function has the value of (-b/2a)
As b=0, then </span><span>the axis of symmetry is (x=0)</span>
After reading through the story problem, I ended up with this equation:
(35-2)(x+.5) =?
or
(35-2)(10+.5)=?
Explanation:
He sells 35 books for usual weeks. Since he is selling his books at $.50 more his average number of copies decreased by 2.
35-2 = 33
Next, we know that he adds $.50 for his price for each copy. If the price is $10 per copy than it looks like this:
$10+$.50= 10+.5
or if the price is not $10 it will be
$x+$.5= x+.5
Answer:
x ≈ 36.2
Step-by-step explanation:
Since the legs are congruent then the triangle is isosceles.
The altitude bisects the base and divides the triangle into 2 right triangles.
Using the right triangle on the right with legs 33 and 15
Apply Pythagoras' identity to the right triangle, that is
x² = 33² + 15² = 1089 + 225 = 1314 ( take the square root of both sides )
x = ≈ 36.2 ( to 1 dec. place )
Answer:
FG = 18
Step-by-step explanation:
24
---E--------------F--------------------------------G
1/3FG
4/3FG = 24
FG= 24×3/4
FG= 6×3
FG= 18
