Answer:
The rate of change is 4
Step-by-step explanation:
The rate of change can be calculated using the formula;
f(b)-f(a)/b-a
According to this question, a = -1 and b = 1
f(a) = f(-1) = 2(-1+1)^2 -3 = -3
f(b) = f(1) = 2(1+1)^2 - 3 = 8-3 = 5
So the rate of change is;
5-(-3)/1-(-1) = (5+ 3)/(1 + 1) = 8/2 = 4
Answer :
98°
Step by step explanation :
As we can see in figure,
∠F = 53°
∠H = 45°
So,

[Angle sum property, which states that the sum of all the angles of a triangle is 180°]
=> ∠FGH + 45° + 53° = 180°
=> ∠FGH = 180° - 98°
=> 
Now,
∠x + ∠FGH = 180°
[linear pair]
=> ∠x = 180° - 82°
=> 
<h2><u>Alternative Method :</u></h2>
We know that sum of two opposite interior angles is equal to the exterior angle.
So
∠x = ∠GHF + ∠HFG.
=> ∠x = 45 ° + 53°
=> 
Hope this helps!
2.8 is the andwer because when you divide 8.40 divide 3 it is equal to 2.8
Answer:
3.45652173913
Step-by-step explanation:
the equation is 159 divided by 46
Answer:
1. x = 15
2. x = 26
3. x = 7.6157731059 (you can round this answer to 8 or 7.6)
4. x = 11.7
5. x = 25
6. x = 1.4
7. x = 22.5
8. x = 38.4
9. x = 10.3 v = 5.8
For some of them, I had to use estimation.
I used this formula : a^2 + b^2 = c^2
