Multiply 3x8y9.2x5y8

ololo11 [35]

Answer:

$6x^{13}y^{17}$

Step-by-step explanation:

We need to multiply

$3x^8y^9.2x^5y^8$

We know the exponent rule of multiplication:

$x^a y^b . x^cy^d = x^{a+c}y^{b+d}$

If the bases are same the powers are added.

So,

$=3*2 *x^8*x^5*y^9*y^8\\=^{8+5}y^{9+8}\\=6x^{13}y^{17}$

So, the answer is:

$6x^{13}y^{17}$

Point (8, 11); Slope =-1/4

Sunny_sXe [5.5K]

Answer:

Step-by-step explanation:

Point (8, 11); Slope =-1/4

y - y₁ = m(x - x₁)

y - 11 = (-1/4 ) (x - 8)

4 * (y -11) = -1 * (x -8)

4y - 44 = -x + 8

x - 8 + 4y - 44 = 0

x + 4y -52 = 0

The half-life of a radioactive kind of tellurium is 25 minutes. If you start with 88 grams of it, how much will be left after 50

LUCKY_DIMON [66]

Notice that 50 minutes is twice the half-life.

After 25 minutes, half of the starting amount remains, so that 88g decays to 44g.

After another 25 minutes (a total of 50 minutes), the 44g will decay to 22g.
