7/10
9/10 - ____ = 2/10
9 - 7 = 2
So, 9/10 - 7/10 = 2/10 or 1/5
Answer:
Step-by-step explanation:
perimeter = l + b + l + b or 2(l + b)
92 = 19 + 19 + 2b
92 = 38 + 2b
2b = 92 - 38
2b = 54
b = 54 / 2
b = 27
breadth or width of the triangle = 27
length = 19
Answer:
0.1, 0.36, 0.72, 4
Step-by-step explanation:
Answer: x-2
Step-by-step explanation:
The tangent line to a curve is the one that coincides with the curve at a point and with the same derivative, that is, the same degree of variation.
We have then:
y = 5x-x²
Deriving:
y '= 5-2x
In point (1, 4)
The slope is:
y (1) '= 5-2 * (1)
y (1) '= 3
The equation of the line will be:
y-f (a) = f '(a) (x-a)
We have then:
y-4 = 3 (x-1)
Rewriting:
y = 3x-3 + 4
y = 3x + 1
Answer:
the tangent line to the parabola at the point (1, 4) is
y = 3x + 1
the slope m is
m = 3
