The population of bees has been decreasing at a rate of 10% per year in 2012 there were 6000 bees in particular hive how many bees were there in 2014

Answers

2012 = 6000 bees
10% of 6000 is 60
so 6000 - 60 = 5940
2013 = 5940 bees
10% of 5940 = 59.4
so 5940 - 59.4 = 5880.6
so in 2014 you 5881 because you cant have a 0.6 of a bee

Write an equation of the line through (5,5)and parallel to the line 4x+3y=-2

Please help

Answers

First out the equation 4x + 3y = -2 into slope-intercept form (y = mx + b).

4x + 3y = -2

Subtract 4x from both sides.

3y = -4x - 2

Divide all terms by 3.

y = -4/3x - 2/3

The slope in this equation is -4/3 (4 down, 3 to the right).

Using that slope, input the coordinates (5, 5) into the equation of a line:

y - y1 = m(x - x1)

y - 5 = -4/3(x - 5)

y - 5 = -4/3x + 20/3

y = -4/3x + 35/3

The equation of the line is y = -4/3x + 35/3.

When the function f(x) is divided by x-2 the quotient is 3x^2+8x-4 and the remainder is 9 find the function f(x) and write the result in standard form?

Answers

dividend ÷ divisor = quotient + remainder
∴ dividend = divisor(quotient) + remainder ... there is a reason why I am not multiplying the remainder by the divisor in this case... your remainder is not represent as a fraction with the divisor as the denominator..

The expression for the function f(x) in standard form is f(x) = 3x³ + 2x² - 20x + 17 if the function f(x) is divided by x-2.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

When the function f(x) is divided by (x - 2) the quotient is 3x² + 8x - 4 and the remainder is 9

By using the division algorithm:

f(x) = (x - 2)(3x² + 8x - 4) + 9

After simplification:

f(x) = 3x³ + 8x² - 4x - 6x² - 16x + 8 + 9

f(x) = 3x³ + 2x² - 20x + 17

Thus, the expression for the function f(x) in standard form is f(x) = 3x³ + 2x² - 20x + 17 if the function f(x) is divided by x-2.

LANDSCAPING The equation 3x+7y =105 represents the number of bags of sand x and bags of multch y that can be bought with $105. If no bags of sand are bought, how many bags of mulch can be bought with $105 ?

Answers

You could buy 15 bags of mulch with $105.
To find the answer, plug in 0 for x since you aren't buying any bags of sand and then you have 7y=105 and divide by 7 to find y which is 15.

Final answer:

When no bags of sand are bought, you can buy 15 bags of mulch with $105.

Explanation:

To find the number of bags of mulch that can be bought with $105 when no bags of sand are bought, we need to substitute x = 0 into the equation 3x+7y = 105. This will allow us to solve for y.

Since x = 0, the equation becomes:

3(0) + 7y = 105

0 + 7y = 105

7y = 105

Dividing both sides by 7, we get:

y = 15

Therefore, when no bags of sand are bought, you can buy 15 bags of mulch with $105.

Triangles XYZ and PQR are drawn on a square grid. What fraction of the area of triangle XYZ is the area of trianglePQR?

Answers

The area of a triangle is given by [tex] \frac{1}{2} bh[/tex].

From the given figure: The base of the bigger triangle is 6 units and the height is 3 units.
The base of the smaller triangle is 3 units and the height is 2 units.

The area of the big triangle is [tex] \frac{1}{2} \times6\times3=9\, square\, units[/tex]
The area of the small triangle is [tex] \frac{1}{2} \times3\times2=3\, square\, units[/tex]

The required fraction is [tex] \frac{3}{9} = \frac{1}{3} [/tex]

To determine the fraction of area of triangle XYZ that is occupied by triangle PQR on a square grid, we can compare their linear dimensions and use the fact that area is proportional to the square of these dimensions, or we can approximate the area through summation of small rectangular areas on the grid. Alternatively, vector methods such as the cross product can provide precise area calculations for triangles with known vertices.

Finding the Area of Triangles on a Square Grid

To find what fraction of the area of triangle XYZ is the area of triangle PQR, we follow several steps. First, we can draw both triangles on a square grid and establish their respective areas. If we assume that XYZ is the larger triangle and PQR is the smaller one, we can use the fact that area scales in proportion to the square of the linear dimensions. This means, if the linear dimensions of PQR are half that of XYZ, the area of PQR would be one-fourth that of XYZ. In mathematical terms, if the side length of XYZ is scaled by a factor of 's', the area is scaled by s².

Another method to approximate the area of irregular shapes like these triangles, as mentioned in a reference, is by dividing the shape into smaller, manageable rectangular areas whose sum approximates the total area. Counting the smallest square units within the grid and making rough estimates of the fractional squares can yield the area as well.

To demonstrate the calculation of the area of a triangle through vector methods, one can use the cross product of two vectors defined by the triangle's vertices. Given vertices A(1,2,3), B(2,4,5), and C(1,-8,0), their position vectors can be used to compute the cross product, and the magnitude of this cross product gives twice the area of the triangle ABC. This is a more advanced method and offers a precise way to calculate the area without relying on the grid.

Answer: The original area of the square is 64 square feet

-------------------------------------
-------------------------------------

Let x be the original side length of the square. The original area is therefore going to be x*x = x^2. For now we don't know the area but once we figure out x, we can compute the area.

The original side length x is increased by 7 ft to jump up to (x+7) ft
At the same time, the other dimension is reduced to (x-2) ft, which is a decrease of 2 ft

The old square is x ft by x ft with area x*x = x^2

The new rectangle is (x+7) ft by (x-2) ft

Let's find the area of this rectangle

Have a look at the image attachment to see how to multiply out (x+7)*(x-2) using the box method

The terms in red are x^2, 7x, -2x and -14 which are found by multiplying the headers

x times x = x^2
x times 7 = 7x
-2 times x = -2x
-2 times 7 = -14

The like terms are 7x and -2x which combine to 5x

Overall the result of multiplying out (x+7)*(x-2) is x^2+5x-14

Note: we can get the same result if we use the FOIL or distribution rule. The box method is a handy way to visually keep track of all the terms.

-------------------------------------

The area of the rectangle, in terms of x, is x^2+5x-14

We are told that the area is 90 square feet

So equate the two expressions and solve for x

x^2+5x-14 = 90
x^2+5x-14-90 = 90-90
x^2+5x-104 = 0
(x-8)(x+13) = 0 ... see note below
x-8 = 0 or x+13 = 0
x = 8 or x = -13

note: find two numbers that multiply to -104 and add to 5. Those numbers are -8 and 13 which helps us factor

We ignore x = -13 as a negative side length makes no sense

The only practical root is x = 8

The side length of the original square is 8 feet

The area is
x*x = 8*8 = 64 square feet

We can check the answer by adding 7 to 8 to get 15, and subtracting 2 from 8 to get 6. The 8 by 8 square turns into a 15 by 6 rectangle. Since 15*6 = 90, we have confirmed the right answer.
