What is 9 times 52 using mental math property

arsen [322]

Everyone works differently in mental meth.

To calculate 9*52, we note that 9=10-1, so mentally calculate
9(52)
=(10-1)(52)
=520-52 [ subtract 20 from each number]
=(520-20)-(52-20)
=500-32
=468.

Alternatively,
9*52=9*50+9*2=450+18=468

If you're good with multiplication and division,
9*52=3*3(52)=3*156=450+18=468

Describing Key Features of a Graph of a Polynomial Function:

Diano4ka-milaya [45]

End behavior:

The parent function is: f(x) = x³, which starts (from the left side) at -∞ and ends (on the right side) at +∞.

Zeroes:

f(x) = x³ + 2x² - 8x

0 = x³ + 2x² - 8x

0 = x(x² + 2x - 8)

0 = x(x + 4)(x - 2)

0 = x 0 = x + 4 0 = x - 2

x = 0 x = -4 x = 2

Intervals:

Put the zeroes in order: -4, 0, 2

since f(x) is increasing from the left then the interval from -4 to 0 is positive and the interval from 0 to 2 is negative.
