There are 7 cards. The number of possible correct picks is 2 (if you pick an 'S') plus 1 (if you pick the 'U') = 3 ways to succeed. So the probability of success is 3/7 ... about 43% .
You need to multiply another number each time.
For Example:
3x2=6
6x3=18
18x4=72
72x5=360
360x6= 2,160
It's a pattern
Answer: The equations of the tangents that pass through
y = -x- 1 and
y = 11x -25
Step-by-step explanation: The gradient of the tangent to a curve at any particular point is given by the derivative of the curve at that point. So for our curve (the parabola) we have
y= x^2 +x
Differentiating wrt x we get:
dy/dx = 2x +1
Let P (a, B) be any generic point on the curve. Then the gradient of the tangent at P is given by:
Answer:
First of all, we can see that this shape have 4 90° angles.
Secondly, since x = 5 we have:
3 × 5 -2 = 15 - 2 = 13 (cm)
And: 5 + 8 = 13 (cm)
=> The two adjacent sides that make up the angle is equal to each other
So this shape is a quare.
=> This shape is a square.
