Answer:

a. [tex]18x^3 -60x^2 + 33x - 45[/tex]

b. No

Step-by-step explanation:

Given:

(3x-9) and [tex]6x^2-2x+5[/tex]

=> the production of them is:

[tex](3x-9)(6x^2-2x+5)[/tex] , we will use distributive law to solve this To do that. we first multiply  [tex]6x^2-2x+5[/tex] by 3x then by -9. This is done as follows

= [tex]3x (6x^2-2x+5) - 9(6x^2-2x+5)[/tex]  [tex]= (3x * 6x^2-3x * 2x+3x *5) - (9* 6x^2-9* 2x+9* 5)\\\\= (18x^3 -6x^2+ 15x) - (54x^2 - 18x +45)[/tex]

Then Open both brackets

= [tex]18x^3 -6x^2+ 15x -54x^2 + 18x -45[/tex]

After that, we group the same terms

= [tex]18x^3 -(6x^2 +54x^2)+ (15x + 18x) -45[/tex]

= [tex]18x^3 -60x^2 + 33x - 45[/tex]

(b) Is the product of (3x-9) and  [tex]6x^2-2x+5[/tex]  equal to the product of (9x-3) and [tex]6x^2-2x+5[/tex]

No, let find the product of (9x-3) and [tex]6x^2-2x+5[/tex] , we will use distributive law to solve this as the above example.

= (9x-3)[tex](6x^2-2x+5)[/tex]

= [tex]9x (6x^2-2x+5) - 3(6x^2-2x+5)[/tex]

=[tex](9x * 6x^2 - 9x * 2x + 9x *5) - (3* 6x^2 - 3 * 2x + 3* 5)[/tex]

= [tex](54x^3 - 18x^2+ 45x) - (18x^2 - 6x +15)[/tex]

After that, we open the bracket to find the same terms

= [tex]54x^3 - 18x^2+ 45x -18x^2 + 6x -15[/tex]

= [tex]54x^3 - 18x^2 -18x^2 + 45x + 6x -15[/tex]

= [tex]54x^3 - 36x^2 + 51x -15[/tex]  

As you can see [tex]54x^3 - 36x^2 + 51x -15[/tex]   ≠[tex]18x^3 -60x^2 + 33x - 45[/tex]

Hope it will find you well.

This is an incomplete table of horsepower and gas mileage data for various 2007 vehicles. Despite the missing information, it can still be used to analyze patterns, create averages, and compare specific models or power ratings.

The presented data appears to be a compilation of horsepower ratings and expected gas mileage (MPG) readings for a variety of 2007 vehicles, as reported by Kelly Blue Book. Unfortunately, the table is incomplete, without consistent information for each listed vehicle, but it can still be analyzed to some extent. You could use this data in mathematics to do things like analyze patterns, create averages, and chart the information in graphical form. For instance, you might look at the relationship between horsepower and gas mileage - perhaps higher horsepower means lower gas mileage, or you might find there's no clear pattern at all. Examples of such analyses might include comparing models from the same manufacturer (like the Honda Civic and Honda Accord), or comparing cars with similar horsepower, like the Audi A4 and Buick LaCrosse both with 200 horsepower.

Answer:

336 plants

Step-by-step explanation:

To find the number of tickseed plants that Michael needs to plant in his garden, we have to find the area of the garden first.

We notice that the garden has the shape of a right triangle: so, we have to find the area of the right triangle.

The area of a triangle is given by the formula

[tex]A=\frac{1}{2}bh[/tex]

where

A is the area

b is the length of the base

h is the height of the triangle

From the figure, we see that:

b = 7 m is the length of the base

h = 24 m is the height of the triangle

Therefore, applying the formula, we find the area of the garden:

[tex]A=\frac{1}{2}7\cdot 24 =84 m^2[/tex]

We also know that Michael wants to plant 4 tickseed plants for each square meter of area; therefore, the total number of plants that Michael will plant is 4 times the area of the garden, so:

[tex]N=4A=4\cdot 84=336[/tex]

Answer:

336 tickseed plants

Answer:

The point (56, 1.75) is on the line.

Step-by-step explanation:

Given two points, we can get the slope (m) as follows:

m = (y2 - y1)/(x2 - x1)

where (x1, y1) and (x2, y2) are the points. Replacing with (8, 0.25) and (16, 0.5):

m = (0.5 - 0.25)/(16 - 8) = 0.03125

The point-slope form of a line is:

y - y1 = m(x - x1)

Replacing with data:

y - 0.25 = 0.03125(x - 8)

To know if point (56, 1.75) is on the line, we have to replace x = 56 in the obtained equation and check y-value, as follows:

y - 0.25 = 0.03125(56 - 8)

y - 0.25 = 1.5

y = 1.5 + 0.25 = 1.75

Then, the point is on the line. This means that there are 56 ounces in 1.75 quarts.

Answer:

(x + 3)(3x - 10)

Step-by-step explanation:

[tex]3 {x}^{2} - x - 30 \\ = 3 {x}^{2} + 9x - 10x - 30 \\ = 3x(x + 3) - 10(x + 3) \\ = (x + 3)(3x - 10) \: are \: the \: required \: factors.[/tex]

To factor the expression [tex]3x^2-x-30[/tex], use factoring by grouping. The factored form is (3x + 3)(x - 10).

To factor the expression [tex]3x^2-x-30[/tex], we can use factoring by grouping or the quadratic formula. Let's use factoring by grouping:

Step 1: Multiply the leading coefficient (3) by the constant term (-30) to get -90.

Step 2: Find two numbers whose product is -90 and whose sum is the coefficient of the linear term (-1). In this case, the numbers are -10 and 9.

Step 3: Rewrite the middle term (-x) as the sum of the numbers found in step 2 (-10x + 9x).

Step 4: Group the terms and factor out the greatest common factor from each group (3x(x - 10) + 3(x - 10)).

Step 5: Factor out the common binomial (x - 10) from each group to get the final factored form: (3x + 3)(x - 10).

Answer:

32.8 miles

Step-by-step explanation:

The total time travelled by rider A is 2 hours. If his speed was 12 mph, the distance travelled is 2 * 12 = 24 miles.

The total time travelled by rider A is 3 hours and 30 minutes (so 3.5 hours). If his speed was 9 mph, the distance travelled is 3.5 * 9 = 31.5 miles.

The angle that they make, as rider A was in the direction N 47 E and the rider B was in the direction S 62 E, is equal to 180 - 47 - 62 = 71°

With these values (two distances and a angle between then, we can use law of cosines to find the distance between the bicyclists:

c^2 = a^2 + b^2 - 2ab*cos(angle)

c^2 = 24^2 + 31.5^2 - 2*24*31.5*cos(71)

c^2 = 1075.99

c = 32.8 miles

The distance between the two bicyclist is 32.8 miles

The total time travelled by rider A is 2 hours.

In the case when his speed was 12 mph,

So, the distance travelled is 2 (12) = 24 miles.

Now

The total time travelled by rider A is 3 hours and 30 minutes i.e. 3.5 hours).

In the case when his speed was 9 mph, the distance travelled is 3.5 (9) = 31.5 miles.

Now the direction is

= 180 - 47 - 62

= 71°

Now the distance is

[tex]c^2 = a^2 + b^2 - 2ab\times cos(angle)\\\\c^2 = 24^2 + 31.5^2 - 2\times 24\times 31.5\times cos(71)\\\\c^2 = 1075.99[/tex]

c = 32.8 miles

Step-by-step explanation:

First we have to add 12+16 so we can find how many marbles are left

12+16=38

Then, we subtract it from the total number of marbles.the outcome of this operation would be equivalent to the number of blue marbles

40-38=12

There are 12 blue marbles.

Now, the we have to use experimental probability if you are familiar with the term is that the number of outcomes(the blue marbles) must be over the total sample space(total marbles) in a fraction.

a) Horizontal component:

      [tex]v_{0,x}=v_0\times cos(20\º)=135ft/s\times cos(20\º)=126.86ft/s[/tex]

b) Vertical component:

      [tex]v_{0,y}=v_0\times sin(20\º)=135ft/s\times sin(20\º)=46.17ft/s[/tex]

2. Find the time when the ball runs 380 feet horizontally:

          [tex]x=v_{0,x}\times t\\\\380ft=126.86ft/s\times t[/tex]

          [tex]t= (380ft)/(126.86ft/s)=2.995s\approx 3.0s[/tex]

3. Find the height of the ball when the time is 3.0s

       [tex]y=y_0+v_{0,y}\times t-gt^2/2[/tex]

     [tex]y=3ft+46.17ft/s\times 3.0s-32.174ft/s^2\times (3.0s)^2/2[/tex]

     [tex]y=-3.3ft[/tex]

This result means that the ball does not reach the wall because it has fallen to the ground (when y = 0) before 3.0s.

45 ( please label me brainliest)

Step-by-step explanation:

The constant of proportionality is a factor that describes a linear relationship between two variables. In the context of a car's speed, it can be found by dividing the distance covered by the time taken, giving a result in miles per hour.

The constant of proportionality is a factor used to describe quantities that have a linear relationship. It is the ratio between two directly proportional variables. For example, if the speed of a car increases proportionally with the time spent driving, the constant of proportionality would be the rate the car is moving in miles per hour (mph). It can be found in simple linear equations with the form y = mx + b, where m is the constant of proportionality.

In your case, if you are given a table of values displaying a linear relationship, the constant of mathrm{proportionality} in mph can be found by selecting any two corresponding values (for time and distance in this case), and calculating the rate by dividing the distance covered in miles by the time taken in hours.

This rate (in miles per hour) is your proportionality constant, assuming that the relationship is indeed linear. Therefore, if one assumes the speed remains constant and acceleration is nil, then the speed of the car (in mph) is the constant of proportionality in this context.

If we have a parabola whose equation is:

[tex]y=ax^{2} +bx+c[/tex]

The line of symmetry is calculated as:

[tex]x=\frac{-b}{2a}[/tex]

Now, we have the equation [tex]y=ax^{2}-4x+3[/tex] and the line of symmetry is [tex]x=-2[/tex]

Where:

[tex]b=-4\\c=3[/tex]

So, we can replace [tex]b[/tex] by -4 and [tex]x[/tex] by -2 and solve for [tex]a[/tex] using the following equation as:

[tex]x=\frac{-b}{2a}\\-2=\frac{-(-4)}{2a}\\-2(2)a=4\\-4a=4\\a=-1[/tex]
