A woman leaves home and walks 3 mi. west, and then 4 mi. south. What is the magnitude of her displacement? Note: they are not asking you to add how far she went west and south. They are asking how far she is from home if she went directly back. Think of a triangle.
Answer:
5 milesStep-by-step explanation:
The route makes a right triangle with legs 3 mi and 4 mi, and the hypotenuse of x mi.
Use Pythagorean to find the distance:
x = [tex]\sqrt{3^2 + 4^2}[/tex] x = [tex]\sqrt{25}[/tex]x = 5 milesVector Review Practice Answers:

Step-by-step explanation:
no proof but a g00gle calculator, you're just gonna have to trust me on this one
Answer:
SA = 376.8 in²
Step-by-step explanation:
area of top:
π4² = 50.24 in²
50.24 x 2 = 100.48 in² (for both ends)
area of side:
circumference = 2 x 4 x π = 25.12 in
area = 25.12 x 11 = 276.32 in²

What is the measure of angle PQR?
Answer:
40
Step-by-step explanation:
It tells you what Q, R is for the opening. That means that it is 40
The measure of angle PQR is 70 degrees
We have a right triangle - r is 90 degrees
based on geometric rules: angle RPQ = 20
40 : 2
90 + 20 = 110
110 + x = 180
What is the perimeter of the triangle?
The perimeter of the triangle is 180 degrees
The triangle has 180 degrees.
This means that 180 - 110 =70 degrees.
The measure of angle PQR is 70 degrees.
Ao se olhar para a história da Álgebra, desde os primórdios quando o objeto de estudo eram equações algébricas específicas até o estabelecimento de uma área de pesquisa que hoje é essencialmente abstrata (se levarmos em conta muitos dos problemas considerados atualmente pelos pesquisadores), perceberemos um longo caminho de busca de padrões e sedimentação teórica. Essa mesma história nos ensina como aconteceu o difícil estabelecimento dessa área de conhecimento. Houve a necessidade da construção de uma linguagem simbólica apropriada às questões tratadas aliada à consequente emersão de conceitos algébricos cada vez mais abstratos. Só assim a Álgebra se consolidou como área de conhecimento, área essa que é, portanto, fruto de um desenvolvimento histórico e não inata ao ser humano. Dito de outra forma, o conhecimento da Álgebra precisa do meio social para ser aprendido e assimilado pelo indivíduo. De acordo com a nossa estrutura social, esse ensino compete à escola ou, mais especificamente, à disciplina de Matemática. Calcule o produto dos monômios : (4 y²) . (4y)

Genies is making cookies. She needs 1 2/3 cups of flour for one batch, but she wants to make 2 1/3 batches. Write an equation that can be used to find how many cups of flour genies will need
Equation: (1 2/3)(2 1/3) = x
Answer: 3 8/9 cups
Step-by-step explanation:
x represents the amount of flour she will need in cups.
To solve, convert the mixed numbers to improper fractions and multiply...
1 2/3 becomes 5/3
2 1/3 becomes 7/3
Now we have
(5/3)(7/3) = x
35/9 = x
35/9 is 3 8/9 as a mixed number

A circle has a circumference of 113.04113.04113, point, 04 units.
What is the diameter of the circle?
Answer:
around 36 is the diameter
Step-by-step explanation:
C=2Pir or pi*d
113.04=pi*d
113.04/pi=d
d≈36
give me brainliest[tex]≈[/tex]
36 units is the diameter of the circle.
What is Perimeter?The perimeter of a two-dimensional form is the space surrounding it. It represents the total length of the shape's sides. The units used to measure the sides of the form, such as meters, centimeters, inches, or feet, determine the units used to measure the perimeter.
We can use the formula for the circumference of a circle, C = πd,
where C is the circumference and d is the diameter.
Substituting the given value, we have:
113.04 = πd
To solve for d, we can divide both sides by π:
d = 113.04/π
Using a calculator to evaluate this expression, we get:
d ≈ 36
Therefore, the diameter of the circle is approximately 36 units.

Don’t quite understand.
Answer:
(a) Same slope and different y intercept
Step-by-step explanation:
Given
[tex]y = \frac{3}{7}x + 11[/tex]
[tex]-3x + 7y = 13[/tex]
Required
Are the lines, parallel?
To do this, we first convert both equations to slope intercept;
[tex]y = mx+ b[/tex]
Where
[tex]m = slope[/tex]
So, we have:
[tex]y = \frac{3}{7}x + 11[/tex]
[tex]-3x + 7y = 13[/tex]
Solve for 7y
[tex]7y = 3x + 13[/tex]
Solve for y
[tex]\frac{7y}{7} = \frac{3x}{7} + \frac{13}{7}[/tex]
[tex]y = \frac{3}{7}x + \frac{13}{7}[/tex]
So, the two equations are now:
[tex]y = \frac{3}{7}x + 11[/tex]
[tex]y = \frac{3}{7}x + \frac{13}{7}[/tex]
When two lines have the same slope but different y intercepts, then they are parallel.
Recall that:
In [tex]y = mx + b[/tex]
[tex]m = slope[/tex]
[tex]b = y \ intercept[/tex]
So:
In [tex]y = \frac{3}{7}x + 11[/tex] and [tex]y = \frac{3}{7}x + \frac{13}{7}[/tex]
The slopes are:
[tex]m = \frac{3}{7}[/tex] and [tex]m = \frac{3}{7}[/tex]
The y intercepts are:
[tex]b = 11[/tex] and [tex]b = \frac{13}{7}[/tex]
Since the values of m (the slope) are the same and the values of b (the y intercepts) are differenr, then they are parallel

Seventy million pounds of trout are grown in the U.S. every year. Farm-raised trout contain an average of 32 grams of fat per pound, with a standard deviation of 7.5 grams of fat per pound. A random sample of 34 farm-raised trout is selected. The mean fat content for the sample is 30.5 grams per pound. Find the probability of observing a sample mean of 30.5 grams of fat per pound or less in a random sample of 34 farm-raised trout.
Answer:
0.121 = 12.1% probability of observing a sample mean of 30.5 grams of fat per pound or less in a random sample of 34 farm-raised trout.
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Farm-raised trout contain an average of 32 grams of fat per pound, with a standard deviation of 7.5 grams of fat per pound.
This means that [tex]\mu = 32, \sigma = 7.5[/tex]
Sample of 34:
This means that [tex]n = 34, s = \frac{7.5}{\sqrt{34}} = 1.2862[/tex]
Find the probability of observing a sample mean of 30.5 grams of fat per pound or less in a random sample of 34 farm-raised trout.
This is the pvalue of Z when X = 30.5. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{30.5 - 32}{1.2862}[/tex]
[tex]Z = -1.17[/tex]
[tex]Z = -1.17[/tex] has a pvalue of 0.121
0.121 = 12.1% probability of observing a sample mean of 30.5 grams of fat per pound or less in a random sample of 34 farm-raised trout.

Order of operations on this equation
Answer:
The answers to your questions are given below.
Step-by-step explanation:
x² – 24 = 10x
Using the format given in the question above, we shall determine the value of x as follow:
I. Make the equation equal to zero
x² – 24 = 10x
Rearrange
x² – 10x – 24 = 0
II. Find two numbers that multiply to __ and add to ___
Multiply the first term (i.e x²) and the last term (i.e –24). The result is –24x².
Find two factors of –24x² such that their sum will result to the 2nd term (i.e –10x). The numbers are 2x and –12x
Thus, Find two numbers that multiply to –24x² and add to –10x
III. Factored equation
x² – 10x – 24 = 0
x² + 2x – 12x – 24 = 0
x(x + 2) – 12(x + 2) = 0
(x – 12)(x + 2) = 0
Thus, the factored equation is:
(x – 12)(x + 2) = 0
IV. The solution are:
(x – 12)(x + 2) = 0
x – 12 = 0 or x + 2 = 0
x = 12 or x = –2
Thus, the solutions are x = 12 or x = –2
