Answer:

Step-by-step explanation:

$x = 2\\ w = -1\\ y = 6\\ z = 4\\x^2+4w-2y\\$

$(2)^2 +4(-1) -2(6)\\4 -4 -12\\0-12\\\\=-12$

Answer:

4x² + 4w - 2y

4(2)² + 4(-1) - 2(6)

4×4 + (-4) - 12

16 - 4 - 12

12 - 12

Sort the following functions from asymptotically smallest to asymptotically largest, indicating ties if there are any. You do no

Serhud [2]

Answer:

b. n

d. 2^lgn

c. n^2.1

a. 4^2lgn

Step-by-step explanation:

Logarithm is a function of mathematics which is used to calculate inverse function of exponents. The asymptotically smallest function will be the one that has smallest or no exponents. The exponent function is calculated in reverse when log is applied. The function with highest exponents will be largest asymptotically.

Determine the average rate of change of the function between the given values of the variable. g(x)=2/x ; x=4, x=a

IrinaK [193]

Average rate of change implies the quotient f(4)-f(a)/4-a which equals (1/2-a/2)/4-a=(1-a)/(8-2a) on (4,a)

HELP. It’s LOG form. Since were out of school I forgot how I did this and it’s due so it would be a life saver.

____ [38]

Answer:

see below

Step-by-step explanation:

exponent to log: $a^b$ = c ---> logₐc = b

ie. question 6

log ₁₀(3x+1) = 2 -----> $10^{2} = 3x+1$

that will get you through questions 1 to 3, 5 to 6, and 8

in question 4, all you have to do is know that 2^2 = 4 and 2^3 = 8, by setting the bases equal, you can manipulate the exponents to get 2x+8 = 3x-3

for questions 7 and 9,

remember that:

logₐc + logₐd = logₐ(cd)

logₐc - logₐd = logₐ( $\frac{c}{d}$ )

remember change of base is $log_{a} b = \frac{log_xb}{log_xa}$ , this will be useful if you need your calculator since calculators only have base 10 and maybe if your calculator is good enough natural base e

15=x/4 - 3 how do i solve

zhuklara [117]

Answer: the answer is x=72

Step-by-step explanation:

Step 1: simplify both sides we know 15=x/4 -3 (the x holds a invisible 1)

the equation should look something Like: 15=1/4x-3 then FLIP the equation such as:

1/4x-3=15 then add 3 on both sides so 15+3=18

step 2: our equation is now 1/4x=18 (we see 4 is being divided the opposite of division is multiply) therefor multiply the 18 with 4

18*4=72 which means x=72
