27) 3 (-5) (-7)

When there is no math symbol between numbers it is multiplication.

Multiply from left to right:

3 * -5 = -15

-15 * -7 = 105

28) -2 * 2 (-3) *2 =

-2 *2 = -4

-4 * -3 = 12

12*2 = 24

31) A negative divided by a negative is positive:

-128 / -4 = 32

32 -36 / 2 / 24 /4

Divide the top and bottom first then divide those:

-36 / 2 = -18

24 / 4 = 6

-18 / 6 = -3

You take a 200 milligram dosage of aspirin. During each subsequent hour, the amount of medication in your bloodstream decreases

shepuryov [24]

Answer: The level of aspirin (mg) will be in your bloodstream in 4 hours = 35.70 mg.

Step-by-step explanation:

If the amount is decreasing by r%, then the final amount is given by :-

$A=P(1-r)^t$

, where P = initial value , t= time

Given: P= 200 milligram, r= 35% = 0.35, t= 4 hours

The level of aspirin (mg) will be in your bloodstream in 4 hours = $200(1-0.35)^4$

$=200(0.65)^4\\\\=200\times 0.17850625\\\\=35.70125\approx35.70 \ mg$

Hence, the level of aspirin (mg) will be in your bloodstream in 4 hours = 35.70 mg.

Solve the following exponential equation <img src="https://tex.z-dn.net/?f=3%20%7B%7D%5E%7B2x%20%7D%20%20-%209%20%3D%200" id

Answer:

x = 1

Step-by-step explanation:

Given exponential equation:

$3^{2x}-9=0$

Add 9 to both sides of the equation:

$\implies 3^{2x}-9+9=0+9$

$\implies 3^{2x}=9$

$\textsf{Apply exponent rule} \quad a^{bc}=(a^b)^c:$

$\implies \left(3^2\right)^{x}=9$

$\implies9^{x}=9$

$\textsf{Apply exponent rule} \quad a=a^1:$

$\implies9^{x}=9^1$

$\textsf{Apply exponent rule} \quad a^{f(x)}=a^{g(x)} \implies f(x)=g(x):$

$\implies x=1$
