How does the precise nature of mathematics OR the imprecise nature of language sometimes get in the way of understanding problem

Degger [83]

Answer:

This is because mathematics uses some theories that helps to change words to equations. for example, a tree of height 50m makes a shadow on the ground. an observer standing at angle of 30 degrees, calculate the distance of the man to the tree. we use the the formula, tan (30)=opp/adj

$1 \div \sqrt{3 } = 50 \div x$

$x = 50 \sqrt{3} m$

What are the ordered pairs of thesolutions for this system of equations? f(x) = x^2 – 2x + 3; f(x) = -6x

babunello [35]

First you subtract the two equations

x^2-2x+3-6x

You simplify that and get

x^2+4x+3 = 0

Now we solve using the quadratic formula.

We get x = -1 and x = -3.

Now we find the y values by plugging the x values into the equation.

f(x) is the same as y.

y = (-1)^2 - 2(-1) + 3

y = 1+2+3

y = 6

Now for the other x value.

y = (-3)^2 - 2(-3) + 3

y = 9+9

y = 18

So the two ordered pairs are (-1,6) and (-3,18)

find the volume of the figure. Round to the nearest hundredth if necessary. (figure is not to scale)

ludmilkaskok [199]

The volume is 336 cubic feet

6x8x3 = 144
8x4x6= 192

144+192=336
