How many license plates can be made of the form ? -yy? , where x is a letter of the alphabet and y is a numeral? 0-9?

 45,697,600

Step-by-step explanation:

There are 26 letters in the alphabet and numerals to choose from.  There is nothing that says that letters and numbers cannot be repreated. So,

   X  X  X  X  - Y  Y

= 26·26·26·26·10·10

= 26⁴(10)²

= 45,697,600

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
