-6x-32/5=14 because the 32 has nothing to do with the problem the correct answer is -35/4, -30/5

Answer:

(a) 12π in

(b) 53.5 in

(c) 96 grams

Step-by-step explanation:

In the figure attached, the ornament is shown

(a) four three-quarter circles is equivalent to 4*3/4 = 3 circles. The perimeter of a circle is the total length of the circular portions.

Perimeter of each circle: 2*π*r

The radius is 2 in long, then for 3 circles:

Perimeter = 3*2*π*2 = 12π in

(b) Perimeter of square: 4*side length

The side length of the square is 4 in, then:

Total length of wire needed = 4*4 + 12π = 53.5 in

(c) The wire weighs 1.8 grams per inch, then:

total weight of the ornament = 1.8 grams/in * 53.5 in = 96 grams

Answer:

Model: [tex]y = 14t+\frac{1}{2}(32.16)t^{2}[/tex]

The dog land on the ground after 0.8706 seconds.

Step-by-step explanation:

The model that said the height of the dog above the ground is a model of uniform acceleration motion, so it is:

[tex]y = y_0+v_0t+\frac{1}{2}gt^{2}[/tex]

Where [tex]y_0[/tex] is the initial height, [tex]v_0[/tex] is the initial velocity and [tex]g[/tex] is the gravity.

So, replacing [tex]y_0[/tex] by zero, [tex]v_0[/tex] by 14 feet per second and [tex]g[/tex] by [tex]32.16 ft/s^2[/tex], we get that the model  for the height of the dog above the ground is:

[tex]y = 14t+\frac{1}{2}(32.16)t^{2}[/tex]

Then, the time t when the dog land on the ground is calculated replacing [tex]y[/tex] by zero and solving for t as:

[tex]y = 14t+\frac{1}{2}(32.16)t^{2}\\0 = 14t+\frac{1}{2}(32.16)t^{2}\\0 =t (14 - 16.08t)[/tex]

Now, we have two possible solutions:

[tex]t=0[/tex] or [tex]14-16.08t=0[/tex]

Taking into account that t=0 is the time when the dog leaps into air, the time when the dog land on the ground is equal to 0.8706 seconds and it is calculated as:

[tex]14-16.08t=0\\14=16.08t\\\frac{14}{16.08}=t\\t=0.8706[/tex]

Answer:

The approximate volume of the tube  is 1,005 cm³

Step-by-step explanation:

To find the volume of the tube, we will follow the steps below:

First, write the formula for calculating the volume of a cylinder

volume of a cylinder = πr²h

where r is the radius and h is the height of the cylindrical cardboard tube

from the question given, height is equal to 20 centimeters    and             diameter = 8 centimeters  but diameter = 2r, this implies that r = d/2   hence radius r =8/2 = 4 centimeters

π is a constant and is ≈ 3.14

we can now proceed to insert the values into the formula

volume of a cylinder = πr²h

                                 ≈ 3.14 × 4²× 20

                                   =3.14 × 16× 20

                                    ≈1,005 cm³ to the nearest whole cubic centimeter.

The approximate volume of the tube  is 1,005 cm³

V = (4/3)(3.14)(7 cm)3

V = 1436.755 cm3 = 1437 cm3, rounding to the nearest whole unit as requested.

The sale price of an item normally priced at £110 is £77.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given that all items are reduced by 30% on a sale.

An item that normally priced at £110 reduced by 30%.

So, 30 percentage of £110

= 30% of £110

= 110×30/100

= 3300/100

= 33.

Therefore, the sale price of an item normally priced at £110 is £77.

Answer:   8 (Pi - sqrt(3))

Discussion:

The area of the shaded region is that of the semicircle minus the area of the triangle..

Area of semicircle = 1/2 * Pi * R^2        

    Where R^2 is the square of the radius of the circle. In our case, R ( = OC)

     = 4 so the semicircle area is

    (1/2) * Pi * (4^2) = (1/2) * Pi * 16 = 8 Pi

Area of triangle.

   First of all, angle ACB is a right angle ( i.e. 90 degrees).

     * This is the Theorem of Thales from elementary Plane Geometry. *

  so by Pythagoras

    AC^2 + BC^2 = AB^2

 But CB = 4 (given) and AB = 4*2 = 8 ( the diameter is twice the radius).

 Substituting these in Pythagoras gives

    AC^2 + 4^2 = 8^2 or

    AC^2 = 8^2 - 4^2- = 64 - 16 = 48

    Hence AC = sqrt(48) = sqrt (16*3) = 4 * sqrt(3)

We are almost done! The area of the triangle is given by

   (1/2) b * h = (1/2)  BC * AC = (1/2) 4 * (4 * sqrt(3)) =  8 sqrt(3)

We conclude the area area of the shaded part is

  8 PI - 8 sqrt(3)   = 8 (Pi - sqrt(3))

Note that sqrt(3) is approx  1.7 so (PI - sqrt(3)) is a positive number, as it better well be!

Rewrite 12 as 4*3

Rewrite -24 as 8*3

Rewrite 6 as 2*3

2*3x^2y-3xy+8*3xyy+4*3yy

Factor out common term 3y:

3y(2x^2-x-8xy+4y)

Factor 2x^2-x-8xy+4y:

3y(2x-1)(x-4y)

Your Answer Is 3y(2x-1)(x-4y)

plz mark me as brainliest if this helped :)

The factor of 6x²y − 3xy − 24xy² + 12y² is 3y(2x - 1)(x - 4y)

Given:

6x²y − 3xy − 24xy² + 12y²

find the highest common factor of all the coefficient of each term

6 = 1, 2, 3, 6

6 = 1, 2, 3, 63 = 1, 3

6 = 1, 2, 3, 63 = 1, 324 = 1, 2, 3, 4, 6, 8, 12, 24

6 = 1, 2, 3, 63 = 1, 324 = 1, 2, 3, 4, 6, 8, 12, 2412 = 1, 2, 3, 4, 6, 8, 12

The highest common factor of all the coefficient of each term is 3

So,

6x²y − 3xy − 24xy² + 12y²

= 3y(2x² - x - 8xy + 4y)

(2x² - x - 8xy + 4y) = (2x - 1)(x - 4y)

Therefore,

6x²y − 3xy − 24xy² + 12y = 3y(2x - 1)(x - 4y)

Step-by-step explanation:

3a - 5 = -4b + 1

3a = -4b + 6

a = (-4b + 6)/3

h(a) = (-4b + 6)/3

Answer:

h(a) = [tex]\frac{6-3a}{4}[/tex]

Step-by-step explanation:

Given

3a - 5 = - 4b + 1

Rearrange making b the subject

Add 4b to both sides

4b + 3a - 5 = 1 ( add 5 to both sides )

4b + 3a = 6 ( subtract 3a from both sides )

4b = 6 - 3a ( divide both sides by 4 )

b = [tex]\frac{6-3a}{4}[/tex] , thus

h(a) = [tex]\frac{6-3a}{4}[/tex]

Answer:

B is correct ;)

Step-by-step explanation:

i just did it haha

The option B is the correct answer i.e. the function g(x) can be defined as g(x) = ((1/2)x)².

A function is defined as a relationship between a set of inputs that each have one output.

Notice that the function g(x) passes through the point (2,1). So, the functional value of g(x) at x = 2, i.e. g(2) = 1.

Check which option match this criterion.

Now, for option A,

g(x) = (1/2)x²

and g(2) = (1/2)×2² = (1/2)×4 = 4/2 = 2 ≠ 1

So, option A is incorrect.

For option B,

g(x) = ((1/2)x)²

and g(2) = ((1/2)×2)² = (2/2)² = 1² = 1

So, option B is correct.

Therefore option B is the correct answer i.e. the function g(x) can be defined as g(x) = ((1/2)x)².

The equation representing the inverse relation is given by -

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have a equation that represent inverse variation between x and y.

The equation for inverse relation comes from the equation of straight line. We can write -

x = m/y

xy = m

Critical thinking? We're in trouble.  It's hard for me to tell what grade this is.

Stem and leaf is fine but let's just write out the data.

Rich: 35 37 41 42 43 44 45 48 50 55   n=10

Will: 42 43 44 44 46 47 47 48 49 50    n=10

Use measures of center and measures of variation ...

The three measures of center typically used are the mean, the median and the mode.

Rich's sum = 440 so Rich's mean = 440/10 = 44

Rich's middle values are 43 and 44 so Rich's median = 43.5

All Rich's scores are unique so he doesn't really have a mode.

Will's sum = 460, Will's mean = 460/10 = 46

Will's middle numbers are 46 and 47 so median 46.5

Will's data has two modes tied, 44 and 47.  

OK, so far these say Rich is a better golfer; he has lower mean and median scores than Will.  (Low score is better in golf.)

Let's look at measures of variation.  I'm guessing that they don't want to you calculate standard deviation.  So we'll do range and mean absolute deviation.

The range is max-min.

Rich's range is 55-35=20

Will's range is 50-42=8

Will is more consistent.

Rich's mean is 44, his scores are here; let's calculate absolute deviation:

Score    35 37 41 42 43 44 45 48 50 55

AbsDev  9   7    3  2   1   0     1   4   6 11

Rich's deviations add to 44 so his MAD is 4.4

Will's mean is 46

Score: 42 43 44 44 46 47 47 48 49 50

AbsDev 4  3  2    2  0    1   1     2    3   4

The sum is 22, Will's MAD is 2.2

Based on the measures of variation, Will is a more consistent golfer.  He's on average worse than Rich, but he always manages to stay pretty close to his average while Rich is all over the place.

Still I'd go with Rich for the tournament.
