Quincy found 120 shells during four days at the beach. if quincy found the same number of shells each day, how many shells did he find each day?

Answers

Answer 1

If Quincy finds 120 shells in 4 days, we can use the equation 4x = 120 to find how many shells she found each day. 4x = 120 If we divide both sides by four we get x = 30 So Quincy found 30 shells each day.

Answer 2

120 shells over 4 days
120/4 gives shells per day
30 shells per day.

find all the zeros of the function y=x^3+6x^2+x+6

Answers

Final answer:

The zeros of a function are the values of x for which the function equals zero. The function given here is a cubic function, and finding its zeros can be complex, often requiring numerical methods or advanced mathematical approaches like the cubic formula.

Explanation:

This problem deals with finding the zeros of the cubic function y=x^3+6x^2+x+6. A zero of a function is a value of x for which the function equals zero. You can find the zeros of this function by setting the equation equal to zero and solving for x.

Unfortunately, this particular cubic equation does not have an easy solution using basic algebraic methods. We can't factor it in an easy and straightforward manner. However, you can use numerical methods, or online calculator tools, to get an approximate value for the zeros. Alternatively, you can use the cubic formula (somewhat similar to the quadratic formula), but this requires knowledge of more advanced mathematics.

Please consult your teacher or textbook for more detailed instructions on how to use higher level methods to solve cubic equations. Remember that each method has its own level of accuracy and complexity, so choose the method that best suits your abilities and the requirements of your task.

Which of the following is not a way to prove a quadrilateral is a parallelogram?

Answers

I think it's the second answer choice.

The way to not prove a quadrilateral is a parallelogram is; Show one set of opposite sides of the quadrilateral is congruent.

Parallelogram and Congruence

A parallelogram is a quadrilateral which has opposite sides to be congruent and parallel as the name implies and hence, opposite angles of the parallelogram are congruent.

However, showing one set of opposite sides of the quadrilateral is congruent is not a confirmatory test for a parallelogram, as it evades the parallel law of opposite sides of the Parallelogram.

The recursive rule for the sequence f(n) = 2 + (-3)(n-1) is f(1) = 2 and f(n) = f(n-1) - 3 for n > 1, where each term is 3 less than the previous term.

The given sequence can be expressed as a recursive formula. A recursive formula defines each term of a sequence using the preceding term(s). To find the recursive rule for the sequence f(n) = 2 + (-3)(n-1), let's write out the first few terms:

f(1) = 2 + (-3)(1-1) = 2f(2) = 2 + (-3)(2-1) = -1f(3) = 2 + (-3)(3-1) = -4f(4) = 2 + (-3)(4-1) = -7

Examining the pattern, each subsequent term is 3 less than the previous term. Thus, the recursive rule is:

f(1) = 2f(n) = f(n-1) - 3 for n > 1

This means that, to get the next term in the sequence, we subtract 3 from the previous term, starting with the second term.

A vehicle travels on a highway at a rate of 65 mi/h how long does it take the vehical to travel 25 mi?

Answers

use the velocity formula and solve for time.v=d/t
t=d/v

Substitute your variables and solve.
65 mi/hr = 65 / 3600 mi/second
25 mi / ( 65/3600) = 1384.6 seconds

Answer:

Step-by-step explanation:

A vehicle travels at a rate of 65 m/h, How long does it take the vehicle to travel at 25 miles?

Apply the "distance formula":

d = rt

25 = 65t

25/65 = t

5/13 hour = t

0.385 hour = t

23.08 minutes = t

If a satellite launch has a 97% chance of success, what is the probability of three consecutive successful
launches? ...?

Answers

91%

0.97 ^ 3 = 0.91

= 91%

Answer: The required probability of three consecutive successful launches is 91.27%.

Step-by-step explanation: Given that a satellite launch has a 97% chance of success.

We are to find the probability of three consecutive successful launches.

Let P(A) denotes the probability of the event of the success of the satellite launch.

Then, according to the given information, we have

[tex]P(A)=97\%=\dfrac{97}{100}=0.97.[/tex]

Therefore, the probability of three consecutive successful launches will be

[tex]p\\\\=P(A)\times P(A)\times P(A)\\\\=0.97\times0.97\times0.97\\\\=0.912673\\\\=0.912673\times100\%\\\\=91.2673\%\\\\=91.27\%.[/tex]

Thus, the required probability of three consecutive successful launches is 91.27%.

A furniture company misprinted a sales ad for a living room set but honors the advertised price. For each customer who purchases the living room set, the company suffers a loss of $125. Write a function to represent the company's total loss. What is the value of the function for an input of 50, and what does it represent? ...?

Answers

We can say that there are x customers.
So,
f (x) = 125x
To get how much money the company loses, we can make x equal to 50.
f (50) = 125(50) = 6250
The company loses $6,250 when 50 customers purchase the furniture.

An Antique vase is projected to be worth $1000 in 2 years and $1,300 after 5 years. If the value continues to appreciate at the same rate, what will it be worth in 8 years?

Answers

The value of the antique vase after 8 years with a consistent appreciation rate, it would amount to $1,600.

An antique vase:

Value after 2 years: $1,000

Value after 5 years: $1,300

To find the value after 8 years, we can assume a constant rate of appreciation:

In 8 years, the value will be: $1,000 + ($1,300 - $1,000) = $1,300 + ($1,300 - $1,000) = $1,600

Kurt johnson delivers packages for a delivery company. he receives $7.50 for every package delivered. what does kurt earn in a week if he delivers 48 packages? 360.00 405.00 555.00 640.00

Answers

y = 7.50x.....y = earnings per week , x = number of packages delivered

48 packages.....so x = 48
y = 7.50(48)
y = 360.....so if he delivers 48 packages, he earns $ 360

Answer:

He earned $ 360.00.

Step-by-step explanation:

Given,

The amount he gets for a package of delivery = $ 7.50

The number of packages he delivered in a week = 48,

Hence, the amount he earned in the week = The amount he gets for a package of delivery × The number of packages he delivered

= 7.50 × 48

= $ 360.00

______________________________________________
The question seems incomplete; how can we solve for "x" when we do not know what "y" equals?
__________________________
However, it could be possible to "solve for x" in terms of "y". To so this, we need to isolate ""x" on one side of the equation:
_______________________________

________________________________________
4 *{ y= 1/4 (x) + 3} ;

4y = x + 12 ; Now we can subtract "12" from EACH SIDE of the equation; to isolate "x" on one side of the equation; and to solve for "x":

Point slope formula has fallowing shape:

where x1 and y1 are coordinates of the given point.

in f(x) = -5x + 2 we can see that slope is -5
m = -5

A isnt correct because radius goes from center of circle to any point on circle. Chord on the other hand connects 2 points on circle...

B is also false. Secant goes through circle while tangent only touches it in one point.

C is correct. Chord connects as said before 2 points on circle and in some cases it can connect 2 points in such way that it goes through center which is diameter.

D is not correct because chord doesnt have to pass trought center of circle in order to connect any 2 points on circle.
