Answer:

x = -2

Step-by-step explanation:

The root will touch the axis and bounce off when the exponent is even. In that case, that means (x + 2)² is the binomial that will bounce. Therefore, the root which bounces and touches the x-axis is x = -2.

Step-by-step explanation:

The whole thing is 360 degrees. To me, it looks like the angles in the middle are divided in to 4 equal parts. 360/4=90. Now set the equation equal to 90. 90-6=84, and 84/2=42.

If a and b are positive integers, what is the value of the product ab ? the least common multiple of a and b is 48. the greatest

rjkz [21]

A and b have the greatest common factor 4, so suppose a=4x, b=4y
the least common multiple of 4x and 4y is 4xy, and 4xy=48, so xy=12
ab=4x*4y=16xy=16*12=192

(the integers are either 4 and 48 or 12 and 16, but that's not what is being asked here.)

SVETLANKA909090 [29]

Answer:

0.1419 ( (if upper and lower cases are interchangeable)

0.348 ( if upper and lower cases are distinct letters)

Step-by-step explanation:

Each digit has 36 possible choices as 26+10

computer generates six characters

there are only 26 choices for letters only, (if we assume upper and lower cases are interchangeable)

For number of letters-only arrangements = $26^{6}$ = 308915776
