Answer:

99 degrees

Step-by-step explanation:

measure angle RST= measure angle RSU+ measure angle UST

measure angle RST=81+18

measure angle RST=99 degrees

The measure angle RST is 99 degrees.

To find measure angle RST.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle and corner whether constituting a projecting part or a partially enclosed space.

Given that:

SU is angle bisector of <RST. So it can divide into 2 parts.

Measure angle RST= measure angle RSU+ measure angle UST

Measure angle RST=81+18

Measure angle RST=99 degrees

So, the measure angle RST is 99 degrees.

Step-by-step explanation:

Answer:

-8

Step-by-step explanation:

Answer:

The answer is [tex]\frac{23}{5}[/tex] or [tex]4.6[/tex] .

Step-by-step explanation:

Solve the following equation:

[tex]23 \times \frac{1}{5}[/tex]

-Multiply [tex]23[/tex] and [tex]\frac{1}{5}[/tex] to get

[tex]23 \times \frac{1}{5} = \frac{23}{5} = 4.6[/tex]

So, now you have found the answer.

Answer:

23/5 as an improper fraction or  4 3/5 as a mixed number

or 4.6 as a decimal or 460% as a percent

Step-by-step explanation:

What I did: 23/1 * 1/5

For this, you just multiply numerators and denominators, getting 23/5 as your answer.

Then I simplified that fraction to get 4 and 3/5 as a mixed number. There's a number of ways you can do this, but I just knew 23 goes into 5, 4 times and added the remaining into the fraction.

For the decimal I knew 4 is just 4 as a whole number and i calculated 3/5 as .6 or 60 percent.

For the percent I just removed the decimal, or in other words, shifted the decimal 2 times to the right.

1.92559524e+14

Step-by-step explanation:

6.47 x 10^-15 and 3.36 x 10^-29 are written in scientific notation. In this way, we have a quotient of two numbers written in scientific notation. To solve this problem, we have:

6.47/3.36 x 10^{[-15-(-29)]}=1.92559524 x 10^{(-15+29)}

Therefore 1.92559524 x 10^{14}  or 1.92559524e+14

1.92559254e+ 14 is the correct value of the given expression.

The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.

given a number  6.47x10^-15/3.36x10^-29

Solving this given number using PEMDAS

=> 6.47x10^-15/3.36x10^-29

=> (6.47 * 10⁻¹⁵) / (3.36 * 10⁻²⁹)

=> (6.47 / 3.36) * 10⁻¹⁵ ⁺ ²⁹

=> 1.92559254 * 10¹⁴

in Scientific notation:

=> 1.92559254e+ 14

therefore, the correct value of the given expression is 1.92559254e+ 14.

Answer:

x =-2

Step-by-step explanation:

1/5^(2x - 1) =3125

5^-2x +1 =5^5

1-2x =5

-2x =5-1

-2x =4

X =4/-2

x =-2

Answer:

1/5^-(2x-1) = 3125

Write them in positive exponent form

We get

5^(2x-1) = 3125

5^(2x -1) = 5^5

2x - 1 = 5

2x = 5+1

2x = 6

x = 3

Answer:

1

Step-by-step explanation:

(3²-2³)⁶⁶ = (9 - 8)⁶⁶ = (1)⁶⁶ = 1

(3²-2³)⁶⁶ total​ is 1

To evaluate (3²-2³)⁶⁶, we will first simplify the expression we have in the bracket before carrying out the power operation

From (3²-2³)⁶⁶

(3²-2³) can be simplified as shown below

3² = 3 × 3 = 9

and

2³ = 2 × 2 × 2 = 8

∴ (3²-2³) = (9 - 8) = (1)

∴ (3²-2³)⁶⁶ becomes (1)⁶⁶

(1)⁶⁶ = 1

(NOTE: 1 raised to any power is 1)

Hence, (3²-2³)⁶⁶ total​ is 1

Answer:

0.97087

Step-by-step explanation:

Given the function:

[tex]f(x) = e^{2x} - x - 6[/tex]

Its first derivative is:

[tex]f'(x) = 2e^{2x} - 1[/tex]

Using Newton's method:

[tex]x_{n+1} = x_n - \frac{f(x_n)}{f'(x_n)}[/tex]

and starting with the point:

[tex]x_1 = 0.95[/tex]

we get:

[tex]f(x_1) = e^{2(0.95)} - 0.95 - 6 = -0.26410[/tex]

[tex]f'(x_1) = 2e^{2(0.95)} - 1 = 12.37178[/tex]

[tex]x_2 = x_1 - \frac{f(x_1)}{f'(x_1} = 0.95 - \frac{-0.26410}{12.37178} = 0.97134[/tex]

[tex]f(x_2) = e^{2(0.97134)}- 0.97134 - 6 = 0.00608[/tex]

[tex]f'(x_2) = 2e^{2(0.97134)} - 1 = 12.95485[/tex]

[tex]x_3 = 0.97134 - \frac{0.00608}{12.95485} = 0.97087[/tex]

[tex]f(x_3) = e^{2(0.97087)} - 0.97087 - 6 = -2.6240413 \cdot 10^{-7}[/tex]

Answer:

$112

Step-by-step explanation:

18 × 14 = 252

252 ft = 84 yrds

84 yrds = 28 sq yrds

4 × 28 = 112

Step-by-step explanation:

The area of the carpet is 18 * 14 = 252 sq. ft. In one sq. yard there are 3 * 3 = 9 square feet so 252 / 9 = 28 sq. yards. That means you pay 28 * 4 = $112.

Answer:

True

Step-by-step explanation:

In Functions and Function Notation, we were introduced to the concepts of domain and range. In this section, we will practice determining domains and ranges for specific functions. Keep in mind that, in determining domains and ranges, we need to consider what is physically possible or meaningful in real-world examples, such as tickets sales and year in the horror movie example above. We also need to consider what is mathematically permitted. For example, we cannot include any input value that leads us to take an even root of a negative number if the domain and range consist of real numbers. Or in a function expressed as a formula, we cannot include any input value in the domain that would lead us to divide by 0.

Diagram of how a function relates two relations.

Figure 2

We can visualize the domain as a “holding area” that contains “raw materials” for a “function machine” and the range as another “holding area” for the machine’s products.

We can write the domain and range in interval notation, which uses values within brackets to describe a set of numbers. In interval notation, we use a square bracket [ when the set includes the endpoint and a parenthesis ( to indicate that the endpoint is either not included or the interval is unbounded. For example, if a person has $100 to spend, he or she would need to express the interval that is more than 0 and less than or equal to 100 and write

(

0

,

1

0

0

]

(0, 100]. We will discuss interval notation in greater detail later.

Let’s turn our attention to finding the domain of a function whose equation is provided. Oftentimes, finding the domain of such functions involves remembering three different forms. First, if the function has no denominator or an even root, consider whether the domain could be all real numbers. Second, if there is a denominator in the function’s equation, exclude values in the domain that force the denominator to be zero. Third, if there is an even root, consider excluding values that would make the radicand negative.

Before we begin, let us review the conventions of interval notation:

The smallest term from the interval is written first.

The largest term in the interval is written second, following a comma.

Parentheses, ( or ), are used to signify that an endpoint is not included, called exclusive.

Brackets, [ or ], are used to indicate that an endpoint is included, called inclusive.

The table below gives a summary of interval notation.

Summary of interval notation. Row 1, Inequality: x is greater than a. Interval notation: open parenthesis, a, infinity, close parenthesis. Row 2, Inequality: x is less than a. Interval notation: open parenthesis, negative infinity, a, close parenthesis. Row 3, Inequality x is greater than or equal to a. Interval notation: open bracket, a, infinity, close parenthesis. Row 4, Inequality: x less than or equal to a. Interval notation: open parenthesis, negative infinity, a, close bracket. Row 5, Inequality: a is less than x is less than b. Interval notation: open parenthesis, a, b, close parenthesis. Row 6, Inequality: a is less than or equal to x is less than b. Interval notation: Open bracket, a, b, close parenthesis.

Answer:

a). 2 meters

b). 0.25 meters per week

c). 1.25 meters

Step-by-step explanation:

Thickness of the ice sheet on the lake = 2 meters

Thickness decreases with a constant rate and thickness is modeled by the function,

h(t) = 2 - 0.25t  [t = time or duration in weeks]

a). Initial value of this function will be it's y-intercept,

h(t) = 2 meters

b). Rate of the melting of this sheet  (slope of the line) = 0.25 meter per week

c). After 3 weeks or t = 3 weeks,

h(3) = 2 - 0.25 × (3)

      = 2 - 0.75
