Find the length the length of AB.
Answer:
19 cm
Step-by-step explanation:
I believed the answer is 19 cm because
AC = 7cm
CB= 12cm
AB= AC+CB
AB= AC+CBAB=7cm+12cm
AB=19cm

find a unit vector in the same direction as the vector (-4,7)
To find out the unit vector in the same direction of other vector, we can calculate the magnitude of its vector and then divide all coordinates by the magnitude, remember that the definition of a unit vector is that its magnitude is 1.
We can calculate the magnitude of a 2D vector as
[tex]\Large\displaystyle\text{$\begin{gathered}v = \left(x, y\right)\\ \\\|v\| = \sqrt{x^2 + y^2}\end{gathered}$}[/tex]
I'll call the vector (-4, 7) as v, so the magnitude of v is
[tex]\Large\displaystyle\text{$\begin{gathered}v = \left(-4, 7\right)\\ \\\|v\| = \sqrt{\left(-4\right)^2 + \left(7\right)^2}\\ \\\|v\| = \sqrt{65}\\ \\\end{gathered}$}[/tex]
So the unit vector that i'll call as v with an hat is
[tex]\Large\displaystyle\text{$\begin{gathered}\hat{v} = \frac{v}{\|v\|}\end{gathered}$}[/tex]
The vector divided by its magnitude, when we divide a vector by a scalar it's the same as divide all the coordinates, so
[tex]\Large\displaystyle\text{$\begin{gathered}\hat{v} = \frac{v}{\|v\|}\\ \\\hat{v} = \frac{v}{\sqrt{65}}\\ \\\hat{v} = \frac{\left(-4, 7\right)}{\sqrt{65}}\\ \\ \boxed{\hat{v} = \left(-\frac{4}{\sqrt{65}}, \frac{7}{\sqrt{65}}\right)}\end{gathered}$}[/tex]
We can also remove the square root from the denominator, then
[tex]\Large\displaystyle\text{$\begin{gathered}\hat{v} = \left(-\frac{4}{\sqrt{65}}, \frac{7}{\sqrt{65}}\right)\\ \\\hat{v} = \left(-\frac{4}{\sqrt{65}}\frac{\sqrt{65}}{\sqrt{65}}, \frac{7}{\sqrt{65}}\frac{\sqrt{65}}{\sqrt{65}}\right)\\ \\\hat{v} = \left(-\frac{4\sqrt{65}}{65}, \frac{7\sqrt{65}}{65}\right)\\ \\\end{gathered}$}[/tex]

The dwarf planet Eris has no atmosphere and has been easier to measure than Pluto. At its
largest, the diameter of Eris is 2,338 km. Using 2376.6 km as the diameter of Pluto. As a
percent difference, how much larger is Pluto than Eris?
Answer:
1.6%
Step-by-step explanation:
2376/2338= 1.016
1.016-1 = .016 * 100
1.6%
hope it helps :)
The percent difference is 1.6% Eris larger than Pluto.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
Given that
The diameter of Eris is 2,338 km and
The diameter of Pluto is 2376.6 km
So the ratio of diameter = 2376/2338 = 1.016
The percent difference = (1.016 - 1)×100
The percent difference = 0.016 × 100
The percent difference = 1.6%
Hence, the percent difference is 1.6% Eris larger than Pluto.

solve ln(x^2+x)-ln(x^2-x)=-1
Step-by-step explanation:
Using the following property of logarithms,
[tex]\ln{\left(\dfrac{a}{b}\right)} = \ln{a} - \ln{b}[/tex]
we can write the given equation as
[tex]\ln{(x^2 + 1)} - \ln{(x^2 - 1)} = \ln{\left(\dfrac{x^2 + 1}{x^2 - 1}\right)}[/tex]
[tex]\:\:\:\:\:\:\:\:\:= \ln{\dfrac{x(x + 1)}{x(x - 1)}} = \ln{\left(\dfrac{x + 1}{x - 1}\right)}[/tex]
But recall that [tex]\ln{e} = 1[/tex] so we can write our original equation as
[tex]\ln{\left(\dfrac{x + 1}{x - 1}\right)} = \ln{e}[/tex]
or simply
[tex]\dfrac{x + 1}{x - 1} = e[/tex]
Multiplying both sides by [tex](x - 1),[/tex] we get
[tex]x + 1 = e(x - 1)[/tex]
Solving for x, we get
[tex]x = \dfrac{e + 1}{e - 1}[/tex]

If ab = 5 and a² + b² = 25, then (a + b)2 =?
Answer:
35.
Step-by-step explanation:
a^2 + b^2 = (a + b)^2 - 2ab
Substituting the given values:
25 = (a + b)^2 - 2*5
(a + b)^2 = 25 + 10
(a + b)^2 = 35
simplify without using a calculator :
[log_{x}(64) + log_{x}(4) - log_{x}(8)] ÷[log_{x}(1024)]
Since log(ab) = log(a) + log(b) and log(a/b) = log(a) - log(b) for any logarithm base, we have
[tex]\dfrac{\log_x(64) + \log_x(4) - \log_x(8)}{\log_x(1024)} = \dfrac{\log_x\left(\dfrac{64\times4}8\right)}{\log_x(1024)} = \dfrac{\log_x(32)}{\log_x(1024)}[/tex]
Then using the change-of-base identity, we have
[tex]\dfrac{\log_x(32)}{\log_x(1024)} = \log_{1024}(32)[/tex]
But we also know that 2¹⁰ = 1024 and 2⁵ = 32, so we can back up slightly and instead write
[tex]\dfrac{\log_x(32)}{\log_x(1024)} = \dfrac{\log_x(2^5)}{\log_x(2^{10})} = \dfrac{5\log_x(2)}{10\log_x(2)}[/tex]
Then the logarithms cancel and you're left with 5/10 = 1/2.

In triangle ABC, a = 3, b = 5, and c = 7. Find the approximate value of angle A.
22°
38°
142°
158°
9514 1404 393
Answer:
a) 22°
Step-by-step explanation:
Side 'a' is the shortest side, so angle A will be the smallest angle. Its value must be less than 60°, eliminating the last two answer choices. The actual value can be found from the Law of Cosines.
a² = b² +c² -2bc·cos(A)
cos(A) = (b² +c² -a²)/(2bc) = (5² +7² -3²)/(2(5)(7)) = 65/70
A = arccos(65/70) ≈ 21.7868°
Angle A is about 22°.

Two functions are ________
equivalent if they
produce the same output for a specific input value. always, sometimes, or never
Answer:
always
Step-by-step explanation:
They would always be equivalent if the left side equals the right side no matter what value you place into the variable
Two functions are always equivalent if they produce the same output for a specific input value. always, sometimes, or never.
Given that,
A statement is given, we have to fill the black statement is to be determined.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
Let two function, f(x) , g(x),
at x = a
both functions give the same value, then the two functions are equivalent. So,t wo function are always equivalent if they produce the same output for a specific input value. always, sometimes, or never.
Thus, two functions are always equivalent if they produce the same output for a specific input value. always, sometimes, or never.
