What value is the seven in 762,039.34

You need to decide whether to hire three landscapers or hire just two but buy a faster mower; both options will deliver the same

Westkost [7]

Answer:

I think buying a new mower will be a much more financial sound decision because it can last 3 years, however, if you hire landscapers it will cost significantly much more money than buying a new mower.

Step-by-step explanation:

Reason for this is that:

$18×2000 hours= $36,000 each year

For three years: $36,000×3=$108,000

which is more than $8,000

Hence, buying a new mower would be the better solution.

How do I calculate this? Is there a formula?

<u>Answer:</u>

Height of cables = 23.75 meters

<u>Step-by-step explanation:</u>

We are given that the road is suspended from twin towers whose cables are parabolic in shape.

For this situation, imagine a graph where the x-axis represent the road surface and the point (0,0) represents the point that is on the road surface midway between the two towers.

Then draw a parabola having vertex at (0,0) and curving upwards on either side of the vertex at a distance of $x = 600$ or $x = -600$ , and y at 95.

We know that the equation of a parabola is in the form $y=ax^2$ and here it passes through the point $(600, 95)$ .

$y=ax^2$

$95=a \times 600^2$

$a=\frac{95}{360000}$

$a=\frac{19}{72000}$

So new equation for parabola would be $y=\frac{19x^2}{72000}$ .

Now we have to find the height $(y)$ of the cable when $x= 300$ .

$y=\frac{19 (300)^2}{72000}$

y = 23.75 meters

A, B & C form a triangle where

andrew-mc [135]

Answer:

16.5mm to. 1 decimal place

Step-by-step explanation:

Please check attachment for diagrammatic representation of the triangle.

Since one of the angles of the triangle is 90, this means that we are dealing with a right angled triangle

To find the length of AC, we make use of pythagoras’ theorem which states that the square of the hypotenuse equals the sum of the square of the other two sides. The hypotenuse is the longest side of the triangle which we have as 17.88 mm

Mathematically therefore

17.8^2 = 6.6^2 + AC^2

AC^2 = 17.8^2 - 6.6^2

AC^2 = 283.28

AC = √(273.28)

AC = 16.53 mm

This is 16.5 to 1 decimal place
