Answer:

An eight-digit grid coordinate gives a precision to the nearest 10 meters

Step-by-step explanation:

Grid coordinates are meant to accurately direct to a specific location, using a map that comes with vertical and horizontal lines of equal spacing and numbers attached to each line to map out a location. The crossing vertical and horizontal lines have unique numbers and form small squares known as grid squares.

The more digits in the coordinate of a point the increase in precision an eight- digit gives a precision to the nearest 10 meters

The ratio of boys to girls in a school is 5:4. if there are 500 girls , how many boys are there in the school?

lana [24]

Answer:

The number of boys in the school is;

$625$

Explanation:

Given that the ratio of boys to girls in a school is 5:4;

$5\colon4$

And there are 500 girls in the school.

The number of boys in the school will be;

$\begin{gathered} \frac{B}{G}=\frac{5}{4} \\ G=500 \\ B=\frac{5\times G}{4}=\frac{5\times500}{4} \\ B=625 \end{gathered}$

Therefore, the number of boys in the school is;

$625$

Three roots of the polynomial equation x4 - 4x3 - 2x2 + 12x + 9 = 0 are 3, -1 and -1. Explain why the fourth root must be a real

LiRa [457]

Descares Theorem says that the number of roots of a polynomial is equal to its highest exponent, and the roots could be real and/or imaginary (complex).

However is their is one complex root (a + i.b), it's conjugate is also
a root (a-i.b).

In the equation x⁴ - 4x³ - 2x² + 12x + 9 = 0, we have already 3 roots, then the 4rth cannot be a complex one since we don't have a fifth for its conjugate.

I’m confused in the exponential

Anna [14]

Answer:

this mean in case of multiplying exponents with same base you should add the exponent and keep base same.

example:

${6}^{4} \times {6}^{5 } = {6}^{4 + 5} \\ = {6}^{9}$
