Y varies directly as x and inversely as the square root of w; write the sentence as an equation.

Answers

Answer 1
Y varies directly as x
y = kx

Y varies inversely as the square root of w
y = [tex] \frac{k}{ \sqrt{w} } [/tex]
Answer 2
Final answer:

The relationship where y varies directly as x and inversely as the square root of w can be represented by the equation y = k * (x / sqrt(w)). Here, k is a constant of proportionality.

Explanation:

From the statement given, we can deduce an equation representing a direct proportionality to x and an inverse proportionality to the square root of w.

In mathematics, direct and inverse proportionality relationships are commonly depicted as y = kx and y = k/x respectively, where k is a constant. For direct proportionality, as x increases, y also increases. Contrastingly, for inverse proportionality, as x increases, y decreases.

Given the statement, we can represent the relationship as follows: y = k * (x / sqrt(w)).

Here, y varies directly as x and inversely as the square root of w. The constant k is the constant of proportionality which can be determined based on specific values of x, y and w.

A-They're easier to get than both car loans and credit cards.

Answer:

A.) They are easier to get than both car loans and credit cards.

Step-by-step explanation:

Payday loans are also called cash advance loans or check advance loans.

These loans are comparatively very easy loans for a person to get. These are short term loans that come with high interest rates. The rates are based on the borrower's income and credit profile.

In this loan the principal amount is typically a small portion of the borrower's next paycheck.

Is triangle ABC similar to triangle ADE? Justify your answer.

Answers

They aren't the exact same. But they do look pretty similar

No!  Triangle ABC is not similar to triangle ADE.

Triangle ABC is not similar to triangle ADE because the sides of triangle ADE is not corresponding to that of Triangle ABC.

Similar triangles are triangles that share the same shape but may differ in size. This means that while their corresponding angles are equal, their corresponding sides are proportional.

For two triangles to be considered similar:

Their corresponding angles must be congruent (equal).Their corresponding sides must be in proportion.

In practical terms, this means that if you were to resize one triangle while maintaining the same angle measurements, you could transform it into the other triangle. The concept of similarity plays a crucial role in various mathematical fields, including geometry, trigonometry, and calculus. It enables us to solve problems involving indirect measurements, scale drawings, and geometric relationships.

Answers

Final answer:

No, the classmate is not correct. The difference between (x+2)² and (x²+4) is 4x.

Explanation:

No, your classmate is not correct. The difference between (x+2)² and (x²+4) is not necessarily 0. To find the difference, we need to expand both expressions and then simplify:

(x+2)² = x² + 4x + 4

(x²+4) = x² + 4

So, the difference between the two expressions is (x² + 4x + 4) - (x² + 4) = 4x. Hence, the difference is not 0.

Find the slope and the y-intercept of the equation y − 3(x − 1) = 0.



slope = -3 and y-intercept = -3



slope = 3 and y-intercept = 3



slope = -3 and y-intercept = 3



slope = 3 and y-intercept = -3

Answers

The slope and the y-intercept of the equation y − 3(x − 1) = 0 are: slope = 3 and y-intercept = -3. The correct option is the fourth option (slope = 3 and y-intercept = -3)

To determine the slope and y-intercept of the equation, we will rewrite the equation in the form of the slope-intercept form of the equation of a straight line.

The slope-intercept form equation of a straight line is

y = mx + c

Where m is the gradient

and c is the y-intercept

From the question, the given equation is  y − 3(x − 1) = 0

This can be rewritten in form of the equation of a straight line as

y -3x +3 = 0

Then,

y = 3x - 3

Now, compare this to y = mx + c  (the slope-intercept form of the equation of a straight line)

Then,

m = 3 and c = -3

That is,

slope = 3 and y-intercept = -3

Hence, the slope and the y-intercept of the equation y − 3(x − 1) = 0 are: slope = 3 and y-intercept = -3. The correct option is the fourth option (slope = 3 and y-intercept = -3)

Due to his good credit history, Francis was able to purchase a home with a good interest rate on his loan. Assuming Francis has the ability to choose the length of his loan and the amount of the down payment, what method would help Francis decrease the total cost of the loan? Select the best answer from the choices provided. reducing the down payment increasing the length of the loan increasing the length of the loan and reducing the down payment reducing the length of the loan and increasing the down payment

Answers

Answer:
Reducing the length of the loan and increasing the down payment.

Explanation:
Increasing the down payment will reduce the total amount you will owe to the bank so there will be less interest charges.

The smaller the term, the higher the interest rate but the smaller the time the less the bank will actually receive from you.

Answer:

Reducing the length of the loan and increasing the down payment

Step-by-step explanation:

Assuming Francis has the ability to choose the length of his loan and the amount of the down payment.

The method that would help Francis to decrease the total cost of the loan is - reducing the length of the loan and increasing the down payment.

When a person pays more amount in down payment, then he will have to loan out a smaller amount. And he will have to pay less interest. If the loan is short, the interest to be paid will be less. If the loan term is long, the interest also increases. One has to pay interest for the whole tenure of the loan.

So, if someone wants to reduce the loan amount, he must pay more in down payment.

Laura has $18.45 left after buying a shirt for $16.80 and a sweater for $24.75
How much money did Laura start with?
plz explain

Answers

Just add all the numbers together
18.45+16.80+24.75 which equal $60

If you want to check your answer just subtract the amount spent on the shirt and sweater by 60 and you should get 18.45

Laura started with $60.00 before purchasing a shirt for $16.80 and a sweater for $24.75, and then had $18.45 remaining.

Calculating Laura's Starting Amount

To find out how much money Laura started with, we need to add the amount she spent on the shirt and sweater to the amount she had left over. Laura spent $16.80 on a shirt and $24.75 on a sweater. After these purchases, she had $18.45 remaining.

We calculate the total amount spent by adding the costs of the shirt and sweater together:

Cost of the shirt: $16.80

Cost of the sweater: $24.75

Total spent: $16.80 + $24.75 = $41.55

We now add the amount left after the purchases to find the total amount Laura started with:

Total spent: $41.55

Amount left: $18.45

Total amount Laura started with: $41.55 + $18.45 = $60.00

Answers

Answer: The experimental probability of rolling a 4 is 0.14

Experimental probability of rolling a 4 = (frequency of rolling a 4) / (Total number of rolling the number cube)

Frequency of rolling a 4 = 14
Total number of rolling the number cube = 100

Replacing in the formula above:
Experimental probability of rolling a 4 = 14 / 100
Experimental probability of rolling a 4 = 0.14

Answer:

The experimental probability of rolling a 4 is 0.14.

Step-by-step explanation:

Given : Caleb performed an experiment in which he rolled a number cube 100 times. He recorded the results in a table.

Number Rolled - Frequency - Experimental Probability

1                                 15                    0.15

We use the sine rule for solving triangles.

This is given by the formula,

From the triangle,

[tex] \frac{ \sin(x) }{60} = \frac{ \sin(40) }{50} [/tex]

We multiply both sides of the equation by 60 to get,

[tex] sin(x) = \frac{ 60\sin(40 \degree) }{50} [/tex]


[tex] sin(x) = 0.7713[/tex]



We solve for x to obtain,

[tex] x = arcsin(0.7713)[/tex]


[tex] x = 50.475[/tex]

Why are angles measured in degrees minutes and seconds?

Answers

 The sexagesimal system is a numbering system that uses the base sixty. It is used to measure times (hours, minutes and seconds) and angles (degrees, minutes and seconds). In this system, 60 units of an order form a unit of higher order. Thus, 60 seconds form 1 minute, and 60 minutes form 1 hour or 1 degree, according to time or angles.
 
 The use of the number sixty as a basis for the measurement of angles, coordinates and time measurements is linked to old astronomy and trigonometry. It was common to measure the elevation angle of a star and trigonometry uses right triangles.
