Answer:
x≅11.49 or x=2√33
Step-by-step explanation:
8^2+x^2=14^2
64+x^2=196
(subtract 64 from both sides)
x^2=132
(square root both sides)
x≅11.49
The vertex form of a quadratic function is f(x) = a(x - h)2 + k. What is the vertex of each function? Match the function rule with the coordinates of its vertex.
Answer:
For [tex]f(x)=6(x-5)^2-9[/tex] the vertex is: (5, -9)
For [tex]f(x)=9(x+5)^2-6[/tex] the vertex is: (-5, -6)

The domain of f(x) is the set os all real numbers greater than or equal to 0 and less than or equal to 2. True of false
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. Row 7, Inequality: a is less than x is less than or equal to b. Interval notation: Open parenthesis, a, b, close bracket. Row 8, Inequality: a, less than or equal to x is less than or equal to b. Interval notation: open bracket, a, b, close bracket.
PLEASE HELP 1) A lake near the Arctic Circle is covered by a 2-meter-thick sheet of ice during the cold winter
months. When spring arrives, the warm air gradually melts the ice, causing its thickness to
decrease at a constant rate modeled by h(t) = 2 - 0.25t, where h(t) represents the thickness of
the sheet of ice and t represents the time in weeks.
a. What is the initial value of this function?
b. What is the rate at which the ice sheet is melting?
c. How thick will the ice sheet be after 3 weeks?
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
= 1.25 meters

Wich is the result of 23*1/5?
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.

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

Which calculator correctly shows the quotient 6.47x10^-15/3.36x10^-29
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.
What are mathematical operations?
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

f(x) = e2x- x-6 closet to the point 0.95
Leave
your answer to five decimal places
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]
what is (3²-2³)⁶⁶ total
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

You bought carpet for a room that measures 18 feet by 14 feet Carpet costs $4.00 per square yard. How much did you pay?
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.
