Which logarithmic equation has the same solution as x-4=2^3

romanna [79]

Answer:

log₁₀ (10¹²)

Step-by-step explanation:

First you should find the solution to the given equation

x-4=2³

x-4=8

x=8+4=12

Now observe the behavior of logarithmic equations with the base 10

log₁₀ 100=2

log₁₀ 10000=4

log₁₀ 1000000=6

To get the answer to

log₁₀ y=12

Then y=10¹².........................how?

check for the first case

log₁₀ 100=2 this can be written as

10²=100

This means to get y in log₁₀y=12 you should rise the base to power 12

y=10¹²

This is to say that

log₁₀ (10¹²) = 12

Find the missing lengths:<br> LO=5 and OK=4, find OH and KH.

hodyreva [135]

Answer:

The length of KH is 6 units and OH is 6.3 units.

Step-by-step explanation:

Given the figure with lengths LO=5 and OK=4. we have to find the length of OH and KH.

In ΔLOH

By Pythagoras theorem

$LH^2=LO^2+OH^2\\\\LH^2=5^2+OH^2$ → (1)

In ΔKOH,

$KH^2=OH^2+OK^2\\\\KH^2=OH^2+4^2$ → (2)

In ΔKHL,

$KL^2=LH^2+KH^2$

Using eq (1) and (2), we get

$KL^2=5^2+OH^2+OH^2+4^2$

$9^2=25+2OH^2+16$

⇒ $2OH^2=81-25-16=40$

⇒ $OH=\sqrt{20}=6.324\sim6.3units.$

Put the above value in eq 2, we get

$KH^2=20+4^2=36$

⇒ KH=6 units.

Which of the following choices is a good estimate for the slope of the Line of Best Fit in the scatter plot?

svetoff [14.1K]

Answer:

A good estimate for the slope is 95/60

Step-by-step explanation:

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

From the graph take the points

(0,0) and (80,125)

substitute

$m=\frac{125-0}{80-0}$

$m=\frac{125}{80}$

simplify

$m=\frac{25}{16}$

Multiply by 3.75 both numerator and denominator

$m=\frac{25*3.75}{16*3.75}$

$m=\frac{93.75}{60}$

$m=\frac{94}{60}$

therefore

A good estimate for the slope is 95/60
