Find the logarithmic function y = logbx that passes through the points

katovenus [111]

$b\in(0,\ 1)\ \cup\ (1,\ \infty)\\x > 0\\y\in\mathbb{R}\\--------------------------\\\\y=\log_bx\\\\For\ (1,\ 0)\to x=1,\ y=0.\ Substitute:\\\\\log_b1=0\to b^0=1\to b\in(0,\ 1)\ \cup\ (1,\ \infty)\\\\For\ (116,\ 2)\to x=116,\ y=2.\ Substitute:\\\\\log_b116=2\to b^2=116\to b=\sqrt{116}\\\to b=\sqrt{4\cdot29}\to b=\sqrt4\cdot\sqrt{29}\to b=2\sqrt{29}\\\\For\ (4,\ -1)\to x=4,\ y=-1.\ Substitute:\\\\\log_b4=-1\to b^{-1}=4\to b=\dfrac{1}{4}$

Different values of b.

<h3>Answer: There is no logarithmic function whose graph goes through given points.</h3><h3 />

Maybe the second point is $\left(\dfrac{1}{16},\ 2\right)$

Substitute:

$\log_b\dfrac{1}{16}=2\to b^2=\dfrac{1}{16}\to b=\sqrt{\dfrac{1}{16}}\to b=\dfrac{1}{4}$

<h3>Then we have the answer:</h3>

$\boxed{y=\log_{\frac{1}{4}}x}$

Equivalent expression for 8+7y+2x+4y+4

KATRIN_1 [288]

Answer:

11y + 2x + 12

Step-by-step explanation:

put similar numbers together:

1. 7y + 4y = 11y

2. 8 + 4 = 12

3. 2x has no match so it is left alone

Put the numbers back together into a new equation: 11y + 2x + 12

Solve for x and round yout answer to the nearest tenth.

Evgesh-ka [11]

Answer:

x=21.35764429=21.4

Step-by-step explanation:

Take SOHCAHTOA

in this problem you're going to use SOH, which is sine= opposite/hypotenuse

sin31=11/x

Multiply by x as a way to isolate it

x(sin31)=11

divide my sin31 to isolate x

x=11/sin31

x=21.35764429

What is the lcm of 15 25 9 8.

posledela

Hi !

So,here we have to calculate the least common multiple of the numbers 15,25,9,8.

<span>We have to break down every number as a prime number product:</span>
15 = 3·525 = 5² 9 = 3² 8 = 2³

Then,we have to select <span> common and uncommon numbers at the highest power so:
</span><span>
</span><span>lcm : 2³·3²·5² = 8·9·25 = 1800
</span>
