Answer:17

Step-by-step explanation:

If the starting number is 12, and the rule is to add 5, then you will add 5 to 12 and get 17. To get the next number you will add 5 to 17 and get 22 . Then add five to 22 and so on.

Evaluate each log without a calculator

QUESTION 1

The given logarithmic expression is

$\log_4(\frac{1}{16})$

We rewrite $\frac{1}{16}$ in the index form to base 4.

This implies that;

$\log_4(\frac{1}{16})=\log_4(4^{-2})$

We now apply the power rule: $\log_a(m^n)=n\log_a(m^n)$ .

$\log_4(\frac{1}{16})=-2\log_4(4)$

Recall that logarithm of the base is 1.

$\log_4(\frac{1}{16})=-2(1)$

$\log_4(\frac{1}{16})=-2$

QUESTION 2

The given logarithm is;

$\log_2(\sqrt[5]{32})$

$\log_2(\sqrt[5]{2^5})$

This is the same as;

$\log_2(2^{5\times \frac{1}{5}})$

$\log_2(2^{1})$

$\log_2(2)=1$

A line has a slope of - 4 and includes the points (6,v) and (3,3). What is the value of v?

labwork [276]

Answer: v = - 9

Step-by-step explanation:

Since two points on the line are given, we use formula for slope.

Let (a,b) and (c,d) be two points on the line, the slope of the line is given by

m= $\frac{d-b}{c-a}$ .

Hence, using this we have

-4= $\frac{3-v}{3-6}$

Thus, we have

-4×(-3)=3-v⇒12=3-v⇒12-3=-v⇒v=-9

Zach bought his parents anniversary gifts. His dad's present cost $25. He bought his mom 3 presents (p) that all cost the same a

zaharov [31]

1) 40-25= 15
2) 15/3=5
3) each gift costs $5

Then to check:
1) 5x3=15
2) 25+15=40
Therefore p=5

HELP! BRAINLEST IF STEP BY STEP SO I CAN UNDERSTAND

vladimir1956 [14]

Since 34 only goes into 7 four times the answer is 28 with a remainder of 6:) so basically you would could by your 7s so 7, 14, 21, 28, 35 and since 35 is too much we would have to go with 28. so then we subtract 28 from 34 and that gives us 6 left over. hoped this helped:))

Write x as a logarithm in the following: 10^x=7

pochemuha

Answer:

x = log 7

Step-by-step explanation:

10^x=7

Take the log base 10 on each side

log10 (10^x)=log10 (7)

We dont need to write the 10, it is implied

log(10^x)=log (7)

The exponent goes out front since log a^b = b log a

x log 10 = log 7

log 10 = 1 since the base is 10 log10(10) =1

x = log 7
