Answer:

A) 13 i think

Step-by-step explanation:

832 , 208 , 52

The difference between 832 and 208 is 624 and then the difference between 208 and 52 is 156. If we check the relation between 624 and 156 which is 624/4 = 156 so then if we divide 156 by 4 we get 39 and then subtract 39 from 52 we get 13.

Answer:

13

Step-by-step explanation:

Inductive reasoning is collecting data to make a conjecture.

Answer:

A) The initial position of the particle is 2 meters.

B) The velocity of the particle at any time t is represented by [tex]v(t) =-2\cdot t +1[/tex].

C) The acceleration of the particle at any time t is represented by [tex]a(t) = -2[/tex].

D) The velocity of the particle at the moment when [tex]s(t) = 0\,m[/tex] is -2 meters per second.

Step-by-step explanation:

A) From statement we know that [tex]s(t) = -t^{2}+t+2[/tex], where [tex]t[/tex] is the time, measured in seconds, and [tex]s(t)[/tex] is the distance, measured in meters. The initial position of the particle is calculated by evaluating the function presented above at [tex]t=0\,s[/tex]. That is:

[tex]s(0) = -(0)^{2}+(0)+2[/tex]

[tex]s(0) = 2\,m[/tex]

The initial position of the particle is 2 meters.

B) According to the Theory on Kinematics, we see that velocity is the rate of change of position in time. In other words, we need to derive the equation once:

[tex]v(t) =-2\cdot t +1[/tex] (1)

Where [tex]v[/tex] is the velocity, measured in meters per second.

The velocity of the particle at any time t is represented by [tex]v(t) =-2\cdot t +1[/tex].

C) And the acceleration is the rate of change of velocity in time. In other words, we need to derive the equation above:

[tex]a(t) = -2[/tex] (2)

The acceleration of the particle at any time t is represented by [tex]a(t) = -2[/tex].

D) At first we solve the function position for [tex]s = 0[/tex], that is:

[tex]-t^{2}+t+2=0[/tex] (3)

[tex](t-2)\cdot (t+1)=0[/tex]

The only reasonable root of the polynomial is [tex]t = 2\,s[/tex].

And now we evaluated the velocity function at given result:

[tex]v(2) = -2\cdot (2) +2[/tex]

[tex]v(2) = -2\,\frac{m}{s}[/tex]

The velocity of the particle at the moment when [tex]s(t) = 0\,m[/tex] is -2 meters per second.

8. Center

As the location of the center of the circle is (3, 3).

9. Endpoints of a diameter

As we know that the diameter is the magnitude (often called the length) of the line through the center.

From the diagram, it is clear that:

Also, observe the length of a diameter is 6 units.

10. A point of Tangency

We know that at the point of Tangency, the tangent to a circle will always be perpendicular to the radius.

From the diagram, it is clear that:

11. Endpoints of a chord that is not a diameter

A chord is basically a line that touches two points.

From the diagram, it is clear that:

12. Endpoints of a radius

We know that a radius is basically a straight line from the center of a circle to the circumference of a circle.

The length of a radius r = diamter length/2

Step-by-step explanation:

I used a calculator if I used my brain it would be wrong.

Answer:

Quite simple. There are 52 weeks in a year. She gets paid 26 times, every other week.

38,350 / 26 = her salary from last year per check.

46,462 / 26 = her new salary per check

(46,462 - 38,350) / 26 = the difference per week

a. last year Beth's biweekly salary was 1597.91 dollars.

b. This year Beth's biweekly salary is 1935.91 dollars.

c. On a biweekly basis she earns 338 dollars more now as a result of her promotion.

One months contains 2 bi-weeks therefore to convert months into bi-weeks we have to multiply the given months by 2.

According to the given question

Last year Beth's annual salary was 38350 dollars.

∴ Her monthly salary was (38350/12) dollars.

= 3195.83 dollars.

She is being paid biweekly meaning twice a month in every two weeks interval.

∴ Her biweekly amount is

=(3195.83/2) dollars

= 1597.91 dollars. (a).

So, her salary last year was 1597.91 dollars biweekly.

This year she received a promotion and now earns 46462 dollars per year.

∴ Her biweekly salary is

= (46462/2×12) dollars.               ( as there is 2 bi-weeks in every months)

= 1935.91 dollars. (b).

As a result of her promotion she earns (1935.91 - 1597.91) dollars more as a result of her promotion.

= 338 dollars.

I did it

answer= 102

Step-by-step explanation:

Given,

Perimeter=46

Let, breadth=X

Then, length = 4X-7

Now,

Perimeter= 2(l+b)

46 = 2(4X-7+X)

46 = 2(5X-7)

(46)÷2 = 5X-7

23+7 = 5X

30 = 5X

30÷5 = X

:-X = 6

Also,

length = 4×6-7 = 17

breadth = 6

Then,

Dimensions = l×b

= 17×6

= 102

Answer:

Step-by-step explanation:

Let 'w' be the width

so the length = 4w - 7

The formula of the Perimeter is

Perimeter = 2(length + width)

         46   = 2(4w - 7+ w)

        46    = 2(5w- 7)

        46    = 10w-14

      46+14 = 10w

         60 = 10w

          w = 6

Step-by-step explanation:

To find the value of [tex]y[/tex], we can add the two equations:

[tex]2x+3y+(-2x+y)=23+13[/tex]

[tex]2x+3y-2x+y=36[/tex]

[tex]y=9[/tex]

To find for [tex]x[/tex], we can use substitution:

[tex]2x+3y=23[/tex]

[tex]2x+3(9)=23[/tex]

[tex]2x=-4[/tex]

[tex]x=-2[/tex]

Answer:

Step-by-step explanation:

step one:

given data

blue fabric costs $9 a yard.

green fabric costs $13 a yard.

Let x represent the number of blue yards of fabric purchased and

let y represent the number of green yards of fabric purchased.

Step two:

The quilter needs at least 9.5 yards of fabric in total.

x+y>=9.5--------1

The quilter can spend up to $110 on fabric.

9x+13y<=110----2

from equation

x+y>=9.5

x=9.5-y

put x=9.5-y in equation 2 we have

9(9.5-y)+13y<=110----2

85.5-9y+13y=110

4y=110-85.5

4y=24.5

y=24.5/4

y=6.125

put y=6.125 in x=9.5-y to find x

x=9.5-6.125

x=3.375

Hence the quilt can purchase

3.375yards of  blue fabric

6.125yards of  green fabric

3.375 yards of blue fabric and 6.125 yards of green fabric was purchased.

Let x represent the number of blue yards of fabric purchased and let y represent the number of green yards of fabric purchased.

Hence:

x + y ≥ 9.5   (1)

The quilter can spend up to $110 on fabric. Hence:

9x + 13y ≤ 110    (2)

The solution to the inequality is:

x = 3.375, y = 6.125

3.375 yards of blue fabric and 6.125 yards of green fabric was purchased.
