Answer:
The ratio 
represents the tangent of ∠I
Step-by-step explanation:
Let us revise the trigonometry ratio
In Δ HIJ
∵ m∠J = 90°
- Hypotenuse is the side which opposite to the right angle
∴ HI is the hypotenuse
∵ HJ = 3 units
∵ IH = 5 units
- Let us use Pythagoras Theorem to find HJ
∵ (HJ)² + (IJ)² = (IH)²
∴ 3² + (IJ)² = 5²
∴ 9 + (IJ)² = 25
- Subtract 9 from both sides
∴ (IJ)² = 16
- take √ for both sides
∴ IJ = 4 units
To find the tangent of ∠I find the opposite and adjacent sides to it
∵ HJ is opposite to ∠I
∵ IJ is adjacent to ∠I
- use the rule of tan above
∴ tan(∠I) = 
∴ tan(∠I) =
The ratio represents the tangent of ∠I
Hi!
Your answer should be: <em>57</em>
<u>Lets do the problem together.</u>
8(5-3)3+9*
*<em>Note, when numbers are next to brackets and there is no mathematical sign, it means multiply. For ex: (1)4=1x4 </em>
First, we start with the parenthesis.
5-3=2
So now, the equation is: 8x2x3+9
Now, we multiply from left to right.
8x2=16
So now, its: 16x3+9
Again, we multiply.
16x3= 48
So now, its 48+9
48+9=57
___________
<em>8(5-3)3+9</em>
<em>=8x2x3+9</em>
<em>=16x3+9</em>
<em>=48+9</em>
<em>=57</em>
<em>___________</em>
Hope this helps!
Let me know if you need anymore help, id be delighted to!

Answer:
x=8
x=3
Step-by-step explanation:
f(x) = −4(x − 8)² + 3
h(x)= -(x-3)² + 2
- <em>The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.</em>
f(x) = −4(x − 8)² + 3
for the first function, the vertex is:
- x-8=0 ⇒ x= 8, this is the axis of symmetry
h(x)= -(x-3)² + 2
for the second function, the vertex is:
- x-3= 0 ⇒ x=3, this is the axis of symmetry, it is also visible on the graph
