Step-by-step explanation:

using the property of logarithms

ln \(x^{n}\) = nlnx ( ln is the natural logarithm )

given

\(17^{(0.3x+5)}\) = 12

take the ln of both sides

ln \(17^{(0.3x+5)}\) = ln 12 , then

(0.3x + 5) ln 17 = ln 12 ( divide both sides by ln 17 )

0.3x + 5 = \(\frac{ln12}{ln17}\) ≈ 0.877063 ( subtract 5 from both sides )

0.3x ≈ - 4.12293 ( divide both sides by 0.3 )

x = \(\frac{-4.12293}{0.3}\) ≈ - 13.7431 ( to the nearest ten thousandth )

Answer:

2/3 quarts

Step-by-step explanation:

Paint used by 9 artists = 6 quarts

So, paint used by 1 artist if shared equally among the 9 artists

= 6 quarts/9

= 2/3 quarts

= 0.6666...... quarts

Rounding to the nearest hundredth, each artist would get approximately 0.67 quarts of paint.

To determine how many quarts of paint each artist gets when six quarts of paint are equally shared among nine artists, we can divide the total amount of paint by the number of artists. 6 quarts ÷ 9 artists = 0.6667 quarts per artist

To "equally share" means to divide or distribute something equally among a group of individuals or entities. It implies that each person or entity involved receives an equal portion or share of the item being distributed. This division ensures fairness and equal opportunities for everyone involved. The goal is to ensure that each recipient receives an equal amount or proportion of the item being shared.

Answer:

The vertex of the function is at (–3,–16)

The graph is increasing on the interval x > –3

The graph is positive only on the intervals where x < –7 and where

x > 1.

Step-by-step explanation:

The graph of \(f(x)=(x-1)(x+7)\) has clear zeroes at \(x=1\) and \(x=-7\), showing that \(f(x) > 0\) when \(x < -7\) and \(x > 1\). To determine where the vertex is, we can complete the square:

\(f(x)=(x-1)(x+7)\\y=x^2+6x-7\\y+16=x^2+6x-7+16\\y+16=x^2+6x+9\\y+16=(x+3)^2\\y=(x+3)^2-16\)

So, we can see the vertex is (-3,-16), meaning that where \(x > -3\), the function will be increasing on that interval

If a company's sales decreased 1% this year, to $7958 then the sales last year was $8036.36.

To find the sales last year, we need to reverse the 1% decrease and calculate it based on the current sales.

Let's denote the sales last year as X.

1% decrease from X can be represented as: X - (1/100) × X

= X - 0.01X

= 0.99X

According to the given information, the sales this year is $7958, which is equal to 0.99X.

0.99X = $7958

To find X, we divide both sides of the equation by 0.99:

X = $7958 / 0.99

X ≈ $8036.36

Therefore, the sales last year were approximately $8036.36.

The digits after the decimal point repeat in a pattern of 6's. This is because 22/6 is a rational number,

A rational number is a number that can be expressed as a ratio or fraction of two integers (a numerator and a non-zero denominator).

We can see that the next three digits in the decimal points are 6, 6 and 6, respectively. Therefore, the decimal equivalent of 22/6 is:

22/6 = 3.666666...

We notice that the digits after the decimal point repeat in a pattern of 6's. This is because 22/6 is a rational number, which means that its decimal representation either terminates (ends) or repeats in a pattern. In this case, it repeats in a pattern of 6's.

Each of the digits after the decimal point will be 6 because this number is a rational number and repeating decimal with a repeating digit of 6.

The difference between 40 and the product of these digits and 6 is always 4.

Answer:

All are rational except 2.36473....

Step-by-step explanation:

Any integers are rational, which means the top option (1000892) is rational.

Anything that can be written as a fraction is also rational, so \(\frac{1}{4}\) is rational.

0.89 can also be written as a fraction as \(\frac{89}{100}\) and 0.37373737... as \(\frac{37}{99}\)

Therefore the only number that is not rational is the last, as it never repeats itself so can't be written as a fraction.

The possible values for a third quiz score that would give her an average between 85 and 90, inclusive is: 97 ≤ x ≤ 112.

In Mathematics, the average of these quiz scores can be calculated by using the following formula:

Average = Sum of quiz score/Number of quiz scores

Note: Let the variable q represent the student's score on the third (3rd) quiz.

Substituting the given parameters into the formula, we have the following;

Average = (75 + 83 + q)/3

Average = (158 + q)/3

This ultimately implies that, an average between 85 and 90, inclusive is given by this compound inequality:

85 ≤ (158 + q)/3 ≤ 90

Multiplying all through by 3, we have the following:

255 ≤ (158 + q) ≤ 270

Subtracting 158 from both sides of the inequality, we have the following:

97 ≤ x ≤ 112

The angle at X connected to S and U is the angle number.

Answer:

Step-by-step explanation:

This is a parallelogram. It's a quadrilateral. All quadrilaterals interior (inside) angles add up to 360 degrees.

Because it's a parallelogram, we know that the opposite angles are equal.

So x is equal to that angle in the opposite corner (diagonal), and 122 is the measure of the other opposite corner angle, too.

So add up those angles:

x + x + 122 + 122 = 360

Combine like terms

2x + 244 = 360

Solve for x

2x = 116

x = 58

Double check that it's correct:

58+58+122+122 = 360.

Answer:

x=58°

Step-by-step explanation:

The sum of the interior angles of a rhombus is 360 degrees. Therefore, if angle A of a rhombus is 122 degrees, then the opposite angle (angle C) is also 122 degrees. The adjacent angles (angle B and angle D) are supplementary to angle A and angle C, meaning that they add up to 180 degrees. So, angle B and angle D are each 180 - 122 = 58 degrees. To summarize, the angles of the rhombus are:

Answer:

144ft^3

Step-by-step explanation:

To start, we have your formula: \(V=\frac{1}{2} (bh) (l)\)
b = base length of the triangle.
h = height of the triangle.
l = length of the prism

Fill in for each of those values:
\(V = \frac{1}{2} (6x6)(8)\)

\(V=\frac{1}{2} (36)(8)\)

\(V=(18)(8)\)

\(V=144\)

Your answer, because it is a 3D shape, should be cubed, so:
\(V=144ft^{3}\)

Step 1: Pick any two points

The points are represented as (x1,y1), (x2,y2).

where x1= -4, y1= -8, x2= 0, y2= 4

Step 2: Write out the formula of the equation to use

The equation that represents the graph is y= 3x+4.

Option A is the correct answer.

Step-by-step explanation:

In an hour, there are 60 minutes.

100km * (12/60) = 20km.

Hence the train runs 20km in 12 minutes.

The correct order from least to greatest is log₂ 26, log₂ 33, log 26, eln 4, the correct option is D.

We are given that;

The logs log, 26, log, 33 and log3 26

Now,

We can simplify these expressions using the following identities:

eln x = x

log a a = 1

log a (b × c) = log a b + log a c

log a (b / c) = log a b - log a c

Using these identities and the properties of logarithms listed above, we can compare the given expressions as follows:

A. eln 4 = 4; log 26 < log 33; so we have:

4 < log 26 < log 33

B. eln 4 = 4; so we have:

log 33 < 4 < log 26 < log 26

C. eln 4 = 4; so we have

log₂ 26 < log 26 < log 33 < 4

D. eln 4 = 4; so we have:

log₂ 26 < log₂ 33 < log 26 < 4

Therefore, by logarithm the answer will be log₂ 26, log₂ 33, log 26, eln 4.
