A weight of 6 lb stretches a spring a distance of 12 in. Find the constant k for the spring.

Answers

Answer:

Let F = the force (6 lbs) and x be the distance that the spring is stretched (12 inches).

F = kx

6 lb = k*(12 in.)

6/12 = k = 0.5 lb/in.

A weight of 6 lb stretches a spring a distance of 12 in. The constant k for the spring will be  0.5 lb/in.

How to obtain acceleration from force applied on an object?

If the object is of mass m kg and force applied on it is of F N in the direction of motion, then the acceleration of that object is evaluated as:

a=  F/m

Given; A weight of 6 lb stretches a spring a distance of 12 in.

Also,

Let F = the force and x be the distance that the spring is stretched

F = kx

6 lb = k*(12 in.)

6/12 = k = 0.5 lb/in.

Therefore, the constant k for the spring will be  0.5 lb/in.

The graph of a linear function is often a parabola.
True or False

Answers

False




.......
.........

A linear function has a graph as a straight line so the given statement is False.

What is a linear function?

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

A linear function is given by

y = mx + c where m is the slope and constant.

Since it is constant it means it should be a straight line in coordinate geometry.

Therefore a linear function always makes a straight line, not a parabola.

Hence "A linear function has a graph as a straight line so the given statement is False".

Which costs more per issue, 18-issue subscription for $40.50 or a 12-issue subscription for $33.60?

Answers

Answer:

12-issue subscription

Step-by-step explanation:

18-issue sub = $40.50 ÷ 18 = $2.25/issue

12-issue sub = $33.60 ÷ 12 = $2.8/tissue

=> The 12-issue subscription costs more per issue (2.8 > 2.25)

Answer:

so you would divide the cost by the issue

the 18 issue is $2.25 per issue

the 12 issue is $2.80 per issue

the 12 issue costs more

Translate X(2,3) Y(0,0) Z(4,4) 2 units right and 3 units up

Answers

Answer:

X(4, 6) Y(2, 3) Z(6, 7)

Step-by-step explanation:

If you want to translate something right on a number line, then you are essentially adding to it. Thus you would just add 2 to each of the x values of the coordinates. The same applies with translating something up, all that really means is that you are adding to each of the y values so all you have to do is add 3 to each of the y values and you get your answer.

Answer:

X:(4,6), Y:(2,3), Z:(6,7)

Step-by-step explanation:

2 units right implies a change on the x-axis, meaning you add 2 units to the x of the coordinate pair (x, y). 3 units up implies a change in Y, you apply the same rule and add 3 to the Y of the pair.

2 units right (add 2 to x pair coordinate)

X: (2,3) --> (4,3)

Y: (0,0) --> (2,0)

Z:(4,4) --> (6,4)

and 3 units up (add 3 to y pair coordinate)

X: (4,3) --> (4,6)

Y: (2,0) --> (2,3)

Z: (6,4) --> (6,7)

For the M1 angle, we can conclude the size of angle is 90°. Do the angle equation like this :

15x=90

x = 90/15

x = 6

Do the same thing in M2 :

Subtitute the x value to equation, then evaluate the value by using 90 because it's the same.

x+y=90

6+y=90

y=90-6

y=84

Salesman Scott received $2,792.79 for selling a property. If the gross commission was 6.5 % of the sale price, the listing salesman received 12% of the gross commission and Scott received 45% of the balance, how much did the property sell for?

Answers

Answer: The property sold for $5,870.41.

Step-by-step explanation:

Let x be the selling price of the property.

Then, gross commission = 6.5% of x = 0.065x

listing salesman received = 12% of ( 0.065x)  = 0.12 (0.065x) = 0.0078 x

Balance = x - ( 0.065x) -  (0.0078 x)

= (1+0.065-0.0078)x

= 1.0572x

Scott received = 45% of (1.0572x)

=0.45 (1.0572x)

= 0.47574x

Now, [tex]0.47574x=2,792.79[/tex]

[tex]\Rightarrow\ x=\dfrac{2792.79}{0.47574}\\\\\Rightarrow\ x=5870.41[/tex]

Hence, the property sold for $5,870.41.

What is the rate of change of the proportion y=9x

Answers

9 is the correct answerNine is the slope and rate of change in that equation.Please let me know if I am wrong.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The rate of change of the proportion y = 9x is 9.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

y = 4x  +2 is an equation.

x + 2x + 3 = 4 is an equation.

We have,

y = 9x

The rate of change of this equation can be calculated by finding its differentiation.

Now,

y = 9x

Differentiating with respect to x we get,

dy/dx = 9dx/dx

dy/dx = 9

Thus,

The rate of change of the proportion y = 9x is 9.

y = mx + b

7x + 8y = -12
Subtract 7x from both sides
8y = -7x - 12
Divide each side by 8

y = -7/8x - 3/2
