Please solve: 8n+2≤8n−9! Show your work please!

1 answer:

4 0

This doesn’t make any sense, because 8n-8n<=-9-2
Which means 0<=-11 which doesn’t make sense, therefore this there are no solutions for this inequality.

What are the means and standard deviations for correct answers from attending a review session

Iteru [2.4K]

The mean from attending a review session will be the average of the numbers that are given.

Your information is incomplete. Therefore, an overview will be given. Mean simply means average.

For example, if the given numbers are 2, 4, 6, and 10. The mean will be:

= (2 + 4 + 6 + 10)/4

=22/4

= 5.5

The ratio is supposed to be pennies to total amount of coins. The total amount of coins--including pennies--is 16. This can be proven by this equation:

5 + 6 + 5 = 16

Now you put the ratio together by taking the amount of pennies (5) and total amount of coins (16). Your ratio should look like this:

5:16

Verify each of the following by evaluating the logarithms.<br> log10(103) + log10(104) = log10(107)

ioda

Answer:

log₁₀(10³) + log₁₀(10⁴)

= log₁₀( 10³ × 10⁴ )

= log₁₀( 10³⁺⁴)

= log₁₀( 10⁷)

Step-by-step explanation:

Given:

log₁₀(10³) + log₁₀(10⁴) = log₁₀(10⁷)

Now,

we know the property of log function that

log(A) + log(B) = log(AB)

therefore,

applying the above property on the LHS, we get

log₁₀(10³) + log₁₀(10⁴) = log₁₀( 10³ × 10⁴ )

also,

xᵃ + xᵇ = xᵃ⁺ᵇ

therefore,

log₁₀( 10³ × 10⁴ ) = log₁₀( 10³⁺⁴)

= log₁₀( 10⁷)

Hence,

LHS = RHS

Hence proved

What is the value of sinθ given that (3, −7) is a point on the terminal side of θ ? −758√58 758√58 358√58 −358√58?

Svetach [21]

Answer:

$\boxed{\sin(\theta)=-\frac{7}{58}\sqrt{58}}$

Step-by-step explanation

The given point $(3,-7)$ tells us that the terminal side of $\theta$ is in the fourth quadrant.

From the diagram in the attachment,

We can use the Pythagoras Theorem to find the length of the hypotenuse of the right triangle.

Let the hypotenuse be $h\: units$ . Then,

$h^2=7^2+3^2$

$h^2=49+9$

$h^2=58$

$\Rightarrow h=\sqrt{58}$

Now we use the sine ratio;

$\sin(\theta)=\frac{Opposite}{Hypotenuse}$ .

But since the terminal side of $\theta$ is in the fourth quadrant, the sine ratio must be negative.

This implies that;

$\sin(\theta)=-\frac{7}{\sqrt{58}}$ .

We rationalize the denominator to get;

$\sin(\theta)=-\frac{7}{58}\sqrt{58}$ .
