The answer is AB= 4.62; mA= 22; mB=68
You could quickly find the answer by just using Pythagorean theorem to find AB.
4.3^2 +1.7^2 = AB^2

Solve 4^x+2=12 for x using the change of base formula logby=logy/logb
yulyashka [42]

Answer:

x = \frac{1}{log(4)}

Step-by-step explanation:

Here, the given expression is :

4^x+2=12

Now, simplifying the given expression ,we get:

4^x+2=12  \implies  4^x=12 - 2 = 10\\\implies 4^x = 10

Now, using the logarithmic property:

log(b -y)=\frac{log (b)}{log(y)}

log(a^m)  = m log(a)

Now, in the expression 4^x = 10take log on the Both sides, we get:

4^x = 10  \implies  log(  4^x ) = log(10)\\\implies x log(4) = 1

or, x = \frac{1}{log(4)}

slope is change in y over change in x

 use 2 points from the table so -3,-21 and -6,-39

change in Y: -39 - -21 = -18

change in x = -6 - -3 = -3

slope = -18/-3 = 6

slope = 6

What is the explicit formula for arithmetic sequence {-20, -5, 10, ...}? Use f(n) where is 1, 2, 3, and so on.
vekshin1
Answer: B

Work:
Since the general formula of an arithmetic sequence is f(n) = (the first term) + (common difference)*(n-1), you just plug in what was given to you in the problem to that equation. The first term is -20 and the common difference is +15 since the the increase from one term to the next is 15. Doing so produces the equation f(n) = -20 + 15(n-1), which is choice B.
