I think it would be 63% because it’s a square and it’s got parallel lines so it’s the same degrees because it’s diagonal

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>

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

You need to spend at least $50 in one day to receive a store discount. You have already spent $30. Let s be the amount of money

Allushta [10]

Answer: s + 30 ≥ 50; s ≥ 20

Step-by-step explanation:

let s be the amount you have yet to spend in order to reach $50 or more

you already have $30.

This means you need to spend at least $20 more ($50 - $30 = $20)

S can be greater than or equal to $20 because your total will be 50 or more, therefore qualifying for the discount.

Use an identity to solve the equation on the interval [0,2pi) sin x cos x = -1/4 x=

dolphi86 [110]

Answer:

<h3>The solution of the given equation is x = 105 °∈ ( 0 , 2pi)</h3>

Step-by-step explanation:

Step(i):-

Given equation is sin x cos x = -1/4

$2(2sinxcosx) = -1$

we know that trigonometry formula

2 sin x cos x = sin 2x

2 ( sin 2 x) = -1

sin2x = -1/2

Step(ii):-

sin2x = $\frac{-1}{2} = sin (\pi +\frac{\pi}{6}$

<h2> sin2x = sin 210</h2><h2> 2x = 7π/6</h2><h2> 2x = 210°</h2><h3> x = 105 °</h3><h3>The solution of the given equation is x = 105 °∈ ( 0 , 2pi)</h3>
