The property shown is commutative multiplication. This property says that the product of two factors is not affected by the order in which they're multiplied. In this case, the product remains the same i.e., 2*8*5 = 80 while 2*5*8 <em>also </em>equals 80.

Answer: p X 0.7

Step-by-step explanation: i think this is the correct answer because when you buy something with a discount you are paying that much less from the initial value (1.0). So your answer would be price X (1.0-discount in decimal form). im really sorry if that was wrong or confusing

Simplify 5(81/3 + 241/3)1/4

madreJ [45]

Answer:

$214\frac{2}{3}$

Step-by-step explanation:

$8\bigg(\frac{81}{3}+\frac{241}{3}\bigg)\frac{1}{4} \\\\= 8\bigg(\frac{81+241}{3}\bigg)\frac{1}{4} \\\\= 8\bigg(\frac{322}{3}\bigg)\frac{1}{4} \\\\= 8\times\frac{322}{3}\times\frac{1}{4} \\\\= 2\times\frac{322}{3}} \\\\= \frac{644}{3}} \\\\= 214\frac{2}{3} \\$

Match each function to the equation of the tangent line to its graph at x = 2.

Llana [10]

1) The function is:

$f(x) = {x}^{2} + 6x - 16$

At x=2,

$f(2) = {2}^{2} + 6(2) - 16 \\ f(2) = 4 + 12 - 16 = 0$

Find the first derivative,

$f'(x) = 2x + 6$

Find the slope at x=2

$f'(2) = 2 \times 2 + 6 = 10$

The equation of the tangent line is given by:

$y - f(2) = f'(2)(x - 2)$

$y - 0= 10(x - 2) \\ y = 10x - 20$

Therefore

$\boxed{f(x) = {x}^{2} - 6x + 16 \to \: y = 10x - 21}$

2) The given function is

$g(x) = {x}^{2} - 49x - 456$

$g(2) = {2}^{2} - 49 \times 2 - 456 = - 550$

$g'(x) = 2x - 49 \\ g'(2) = 2 \times 2 - 49 = - 45$

The equation of the tangent is

$y - g(2) = g'(2)(x - 2) \\ y + 550 = - 45(x - 2) \\ y + 550 = - 45x + 90 \\ y = - 45x + 90 - 550 \\ y = - 45x - 460$

$\boxed{g(x) = {x}^{2} - 45x - 456 \to \: y = - 45x - 460}$

3) The function is

$h(x) = - {x}^{2} - 7x + 44$

Now

$h(2) = - {2}^{2} - 7 \times 2 + 44 = 26$

The first derivative is

$h'(x) = - 2x - 7$

$h'(2) = - 2 \times 2 - 7 = - 14$

The equation of tangent at:

x=2

$y - h(2) = h'(2)(x - 2) \\ y - 26 = - 14(x - 2) \\ y - 26 = - 14x + 28 \\ y = - 14x + 28 + 26 \\ y = - 14x + 54$

$\boxed{h(x) = - {x}^{2} - 7x + 44 \to \: y = - 14x + 54}$

At one store, Matt saved $15 with a coupon for 30% off his total purchase. At another store, the 24$ he spent on books is 48% of

Goryan [66]

STEP 1:

$15 = 30%
Y = 70%

Y = (15x70) / 30
Y = $ 35 (Total purchase at store 1)

STEP 2:

$24 = 48%
Z = 100%

Z = (24x100) / 48

Z = $50 (Total purchase at store 2)

STEP 3:

$35+$50

= $85 (TOTAL PURCHASE)
