Convert the mixed number to an improper fraction first
step 2
To convert the fraction as a percent multiply by 100
Answer:
A non-calculus solution follows afterward.
For a calculus solution, the gradient is the first derivative with the point put in.
y = -x²+3x
dy/dx or y’ = -2x +3 is the gradient at any point.
but the tangent is at x = 2 so put it in
y’ = -(2*2)+3 = -1 is the gradient of the tangent at point (2,2)
Non-calculus solution:
y = -x²+3x 1️⃣but slope of tangent m = (y-2)/(x-2)2️⃣
put 1️⃣ into 2️⃣ and rearrange ⟹ mx-2m+x²-3x+2 = 0
or x²+(m-3)x+2–2m =0
but for a tangent the discriminant b²-ac = 0
(m-3)²-4*1*(2–2m) = 0
m²+2m+1 = 0
(m+1)(m+1) = 0
m = -1 is the is the gradient of the tangent at point (2,2)
Step-by-step explanation:
For this case we must follow the following rules of rounding
1) If the previous number is greater than or equal to five, then the next number increases by one unit
2) If the previous number is less than five, then the next number stays the same
Therefore, the steps for rounding to the nearest tenth is:
1) We observe that 3 is less than 5.
2) Therefore, the next number stays the same
Rounding to the nearest tenth is:
5.6
Answer:
1) We observe that 3 is less than 5.
2) Therefore, the next number stays the same
5.6
32. The absolute value of a number x (|x|) will always be positive. It just means how far the number is from 0 on the number line.
