Answer:

n= 2x-6y

Step-by-step explanation:

So we might look at this and have an immediate panic attack, but if there is one thing we might look to to help us, it would be logarithms. Logarithms have many wonderful properties that will help us solve this equation. Let's get started:

1.  This is the starting equation. [tex](2^{\frac{1}{2} } )^{n} =\frac{2^x}{8^y}[/tex]

2. Let's use the power to power rule on the left and multiply 1/2 by n:

a. [tex]2^{\frac{1}{2}n } =\frac{2^x}{8^y}[/tex]

3. Next, lets take the log of both sides and use the properties of logarithms:

a. [tex]2^{\frac{1}{2}n } =\frac{2^x}{8^y}[/tex]

b. [tex]log(2^{\frac{1}{2}n }) =log(\frac{2^x}{8^y})[/tex]

c. One property we are allowed to use is bringing down the exponent on the left, and another property we can use is when you have the log of a fraction, that is the same thing as the log(numerator)-log(denominator)

d. [tex]\frac{1}{2}n *log(2) =log(2^x)-log(8^y)[/tex]

e. After we do this, we can use the same property of bringing down the exponent on the right side:

f. [tex]\frac{1}{2}n *log(2) =x*log(2)-y*log(8)[/tex]

g. After this, because log(2) and 1/2 are both numbers and are multiplied by n, we can divide them from both sides, and simplify:

h. [tex]\frac{1}{2}n =\frac{x*log(2)-y*log(8)}{log(2)}[/tex]

i. [tex]2(\frac{1}{2})n =2\frac{x*log(2)-y*log(8)}{log(2)}[/tex]

j. [tex]n =2\frac{x*log(2)-y*log(8)}{log(2)}[/tex]

k. After this, we must simplify the fraction because log(2)/log(2)=1, and log(8)/log(2)=3, these are both because 2^1=2 and 2^3=8 respectively:

l. [tex]n =2(\frac{x*log(2)}{log(2)}-\frac{y*log(8)}{log(2)} )[/tex]

m. Lastly, let's cancel and distribute:

n. [tex]n =2(x-3y)[/tex]

o. [tex]n=2x-6y[/tex]

Answer:

1. (5)(8) = (4)(x)

Step-by-step explanation:

We have two chords intersecting each other.

Intersecting chords theorem states that when two chords cut each other, the product of the segments of one is equal to the product of the segments of the other.

Therefore, we would have:

(5)(8) = (4)(x)

Answer:

the answer is .5 I think I'm sorry if I'm wrong

Answer:

1 / 7

Step-by-step explanation:

Given the distribution above :

P(grade B or higher) can be defined explicitly as :

P(Grade A) + P(Grade B)

P(grade A) = 2/35

P(Grade B) = 3 / 35

Hence,

P(Grade B or higher) = 2/35 + 3/35 = 5/35 = 1/7

18.1

Step-by-step explanation:

In solving this question, remember the annotation SOHCAHTOA

1. We are given the value of the hypotenuse and we are to determine the value of the adjacent side. COS would be used to determine this value

Cos 26 = Adjacent / hypotenuse

cos 26 = x / 15

x / 15 =0.8988

x = 15 x 0.8988 = 13.5

2. We are given the value of the hypotenuse and we are to determine the value of the opposite side. SIN would be used to determine this value

Sin = opposite / hypotenuse

sin 49 = x / 24

0.7547 = x / 24

x = 0.7547 x 24

x = 18.1

3. We are given the value of the opposite side and we are to determine the value of the adjacent side. TAN would be used to determine this value

Tan = opposite / adjacent

tan 14 = 18 /x

18 / 0.2493 = 72.2

4.  We are given the value of the adjacent and we are to determine the value of the hypotenuse side. COS would be used to determine this value

cos 67 = opposite / hypotenuse

0.3907 = 5/x

x =5/  0.3907 = 12.8

to determine the missing angle

7. tan^-1 = opposite / adjacent

8. cos^-1 = adjacent / hypotenuse

9 = sin^-1 = opposite / hyotensue

Answer: D) The value of [tex]\sqrt{215}[/tex] is between 14.5 and 15

Step-by-step explanation:

Let's start by taking the squaring these numbers.

[tex]13^2=169\\13.5^2=182.25\\14^2=196\\14.5^2=210.25\\15^2=225[/tex]

215 is in between 14.5 squared and 15 squared. That means its square root will be between 14.5 and 15.5

Step-by-step explanation:

I don't see really the actual answer options (you made a bad copy here).

so, I can only tell you what it is in my own terms and you need to associate to the actual answer option.

based on real numbers (not complex or imaginary) we cannot use the square root function on negative numbers.

the domain defined what values can be used for x.

so,

Answer: c

Step-by-step explanation: just took it

Answer:

for the lengths, just double the numbrrs

1.5 -> 3

2.5 -> 5

bc the scale factor is two (the upper edge is given)

the angles are just the same, no matter the zoom factor

There are two polygons where B is greater than A.

One side in polygon A has a length of 2.5 and the corresponding length in polygon B is 5.

So, the scale factor is

[tex]\dfrac{5}{2.5}=2[/tex]

So, the missing sides in polygon B are

[tex]1.5\times2=3[/tex]

[tex]2.5\times 2=5[/tex]

The angles in polygon A will be the same as B as all the sides of the polygon have changed according to the scale factor.

So, the missing sides in polygon B are 3 and 5, and the angles in polygon A are [tex]53^{\circ}[/tex] and [tex]82^{\circ}[/tex].

Explanation:

Rule: if |x| > k, then x < -k or x > k

Using that rule for the given inequality means we have these steps

|x-4| > 3

x-4 < -3  or x-4 > 3

x < -3+4 or x > 3+4

x < 1  or  x > 7 ..... choice E

-------------

Here's a visual way to see why this is the case.

|x-4| represents the distance from x to 4 on the number line.

When we say |x-4| > 3, we want to know which points are more than 3 units away from 4 on the number line.

We can plot 4 on the number line, and then measure 3 units below it (to get to 1) and then 3 units above it (to get to 7). If we're in the region 1 < x < 7, then we're within 3 units of 4 on the number line. Otherwise, we're more than 3 units away from the target we're after.

Answer:

−0.2542372881

Answer:

length = 12

width = 15

Step-by-step explanation:

if you foil (x+7)(x+10) you get:

x²+17x-110 = 0

the factors are:

(x+22)(x-5) = 0

x = -22 and 5

we can dismiss the negative as irrelevant for a measure; therefore, x = 5

length = 5+7, or 12

width = 5+10, or 15

Answer:

c. normal probability distribution

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

In this question:

By the Central Limit Theorem, it is a normal distribution, so option c.

Step-by-step explanation:

Two poin on this line are (-2, 3) and (0, -3).  Both points are formed where grid lines meet precisely.

The change in x as we go from (-2, 3) to (0, -3) is +2 and the change in y is -6.  Thus, the slope of the line shown is m = rise/run = -6/2, or m = -3.

Answer:

C

625

Step-by-step explanation:

We must first find the length of the side

So remember that the area of a square is side squared

So to find the length of the side we square root A

Since the perimeter of a square is 4 times the side we end up with 4square root(A)

And the whole thing must equal less than 100

So its C

Answer:

0.5185 kg are needed to make 2 kg of cat food

Step-by-step explanation:

Chicken bones and chicken pieces in the ratio 20:7

This means that [tex]\frac{20}{20 + 7} = \frac{20}{27}[/tex] of the total weight is of bones and [tex]\frac{7}{27}[/tex] is of pieces.

What weight of chicken pieces is needed to make 2 kg of cat food?

7/27 of 2kg. So

(7/27)*2 = 14/27 = 0.5185 kg

0.5185 kg are needed to make 2 kg of cat food

Answer:

Angle 2 = 124 degrees

Step-by-step explanation:

Angles 1 and 2 are corresponding angles since the two lines are parallel.

We can put both numbers into an equation.

3x + 25 = 2x + 58

Subtract both sides by 2x which will give:

x + 25 = 58

Now, we can solve for x, which is:

x = 58-25 = 33

Put back x = 33 into angle 2.

Hence, angle 2 is 2*33 + 58 = 124

Answer:

m∠2 = 124 degrees

Step-by-step explanation:

By the definition of "Same Side Corresponding Angles" the 2 angles given are congruent to each other, therefore we can say;

3x + 25 = 2x + 58

x + 25 = 58

x = 58 - 25

x = 33

Now that we have x = 33, we can substitute 33 in for x, in equation given for angle 2 to find it's measure;

∠2 = 2(33) + 58

∠2 = 66 + 58

∠2 = 124

Therefore m∠2 = 124 degrees.
