Answer:

x=75

Step-by-step explanation:

2 * ln (e ^ ln (2x)) - ln (e ^ ln (10x)) = ln (30)

Apply exponent rules

2 * ln (2x) - ln (10x) = ln (30)

Apply log rules

2 * ln (2x) - ln (10x) = ln (30)

Apply log rule: logc(ab) = logc(a) +logc (b)

Apply exponent rules

2 * ln (2x) - ln (10x) = ln (30)

Apply log rules

2 * ln (2x) - ln (10x) = ln (30)

Apply log rule: logc(ab) = logc(a) + logc (b)

ln (2x) = ln (2) + ln (2)

2(ln (2) + ln (x)) - ln (10x) = ln (30)

Apply log rule: logc(ab) = logc(a) + logc (b)

ln (10x) = ln (10) + ln (x)

ln (2x) = ln (2) + ln (2)

2(ln (2) + ln (x)) - ln (10x) = ln (30)

Apply log rule: logc(ab) = logc(a) + logc (b)

ln (10x) = ln (10) + ln (x)

Apply log rule: logc(ab) = logc(a) + logc (b)

ln (10x) = ln (10) + ln (x)

2(ln(2)+ln(x))-(ln(10)+ln(x))=]

Expand 2(ln(2) +ln(x)

ln (x) + 2 * ln (2) - ln (10) = ln (30)

Subtract 2 * ln (2) - ln (10) from both sides

In(x) + 2ln(2) - In(10) - (2ln(2) - In

Simplify

ln (x) = ln (30) - 2 * ln (2) + ln (10)

Simplifify ln (30) - 2 * ln (2) + ln 10

ln (x) = ln (75)

Apply log rule: If logb(f(x)) = logb (g(x)) then f(x) = g(x)

x = 75

Verify Solutions: X = 75

Check the solutions by plugging them

into 2 * ln (2x) - ln (10x) = ln (30) Remove the ones that don't agree with the equation.

Plug in x =75

2 * ln (2 * 75) - ln (10 * 75) = ln (30)

2 * ln (2 * 75) - ln (10 * 75) = ln (30)

ln (30) = ln (30)

The statements that describe the variables x and y are:

In the graph that relates variables x and y (see attachment), we can see that the points are scattered on the coordinate plane and they do not follow a specific pattern.

If the points are scattered, then the graph shows no association.

Hence, the graph shows no association

Answer:

40

Step-by-step explanation:

40 because 39 will round up to 40 by 1

The probability in percentage that the next customer will pay with a debit card will be 68.42%.

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences. Then the probability is given as,

P = (Favorable event) / (Total event)

She knows that in the last week, 13 customers paid cash, 39 customers used a debit card, and 5 customers used a credit card.

The probability that the next customer that will pay with a debit card will be given as,

P = 39 / (13 + 39 + 5)

P = 39 / 57

P = 0.6842 or 68.42%

here the polynomial has degree 6

6 can be all negative or positive

Answer:

Both positive (or) negative

Step-by-step explanation:

The polynomial's degree is 6 and so the polynomial has 6 zeroes. These zeroes can be either positive or negative.

Answer:

5 for both.

Step-by-step explanation:

Multiplying exponents rule with like bases;

Add powers with like bases.

So, if we look at x to the power of the blank multiplied by x to the power of 5, we know that 5 added to that unknown/blank power would equal in 10(using the multiplication of exponents rule), because in the results it says x^10.

Thus,

x to the power of __       ·       x to the power of 5 = x to the power of 10

And, 5 would make a solution for the blank, because;

x to the power of 5      ·       x to the power of 5 = x to the power of 10, which is true because their exponents added together would be 10 → (5 + 5).

Now, if we look at y to the power of 3 multiplied by y to the power of the blank, we know that 3 added to the unknown/blank power would equal in 8(using the multiplication of exponents rule) because in the results says y^8.

Thus,

y to the power of 3       ·       y to the power of __ = y to the power of 8

And, 5 would make a solution for the blank, because;

y to the power of 3       ·       y to the power of 5 = y to the power of 8,  which is true because their exponents added together would be 8 → (3 + 5).

Overall you're basically just multiplying all those exponents together.

Answer:

y = 3/5x + 1

Step-by-step explanation:

Formula:

y - y1 = m(x - x1)

Plug in:

y - (-2) = 3/5(x - (-5))

Two negatives make a positive:

y + 2 = 3/5(x +5)

Distribute 3/5 to (x + 5):

y + 2 = 3/5x + 3

Get y by itself by - 2:

y = 3/5x + 1

Step-by-step explanation:

If two solids are similar with a scale factor of a/b, then the surface areas are in a ratio of [tex]\rm \left (\dfrac{a}{b } \right )^2[/tex].

If two solids are similar with a scale factor of a/b, then the volumes are in a ratio of [tex]\rm \left (\dfrac{a}{b } \right )^3[/tex].

Two shapes are similar if all their corresponding angles are congruent and their corresponding sides are proportional.

Two solids are similar if they are the same type of solid and their corresponding radii, heights, base lengths, widths, etc. are proportional.

When two shapes are similar in two dimensions, the ratio of their areas is the square of the scale factor.

A comparable relationship holds in three dimensions as well.

Surface Area Ratio: If two solids are similar with a scale factor of a/b, then the surface areas are in a ratio of [tex]\rm \left (\dfrac{a}{b } \right )^2[/tex].

Volumes of Similar Solids; Just like surface area, volumes of similar solids have a relationship that is related to the scale factor.

Volume Ratio: If two solids are similar with a scale factor of a/b, then the volumes are in a ratio of [tex]\rm \left (\dfrac{a}{b } \right )^3[/tex].

Answer:

Area = 245 ft

(Width

Step-by-step explanation:

l = 5w

Where l is length and w is width.

We also know that the perimeter is 84 ft, so:

2l + 2w = 84

Now we can plug in 5w for l since we found the equality earlier:

2(5w) + 2w = 84

and then solve for w:

10w + 2w = 84

12w = 84

w = 7

so

l = 5 × 7

l = 35

The length is 35 and width is 7 so

the area of the rectangle is

[tex]\textsf{Let}\:(x_1,y_1)=(h,k)[/tex] → new center of the circle

[tex]\textsf{Let}\:(x_2,y_2)=(x,y)[/tex] → point on the circle

Therefore, the radius (r) is the distance between (x, y) and (h, k)

Use the distance formula:

[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}=d[/tex]

[tex]\implies \sqrt{(x-h)^2+(y-k)^2}=r[/tex]

x = 16

m

Angle1 = 80°

mAngle2 = 10°

Step-by-step explanation:

Angle 1 + Angle 2 adds up to 90°. The tiny square in the corner of the image shows you that the whole thing is 90°.

So write the equation base on that.

5x + x - 6 = 90

Combine like terms(add the x's)

6x - 6 = 90

Add 6.

6x = 96

Divide by 6.

x = 16

Fill in 16 for x to find the measures of the angles.

Angle 1 = 5x

= 5(16)

= 80°

Angle 2

= x - 6

= 16 -6

= 10°

And 80°+ 10° is 90° so that's a good check. Hope this helps!
