Which polynomials are in standard form?

xeze [42]

Polynomials in standard form:

$t^4 - 1\\\\-2t^2 + 3t + 4\\\\4t - 7$

Solution:

Standard form of polynomials: terms are ordered from biggest exponent to lowest exponent

Option A:

$t^4 - 1$

The above is a polynomial

Where, largest exponent is arranged first

Therefore, it is standard form of polynomial

Option B

$-2t^2 + 3t + 4$

Here, exponents are from greatest to least

Therefore, it is standard form of polynomial

Option C

$4t - 7$

Here, "t" is a variable. The first term has largest degree

Therefore, it is standard form of polynomial

Geometry math question

Look at the picture.

Let |AE| = |AD| = b

We have a proportion:

$\dfrac{x}{13}{y}=\dfrac{19}{y+a}=\dfrac{x}{y+2a}$

Solve for y from first proportion

$\dfrac{13}{y}=\dfrac{19}{y+a}\ \ \ |\text{cross multiply}\\\\19y=13(y+a)\\\\19y=13y+13a\ \ \ \ |-13y\\\\6y=13a\ \ \ |:6\\\\y=\dfrac{13}{6}a$

Substitute to the second proportion

$\dfrac{19}{y+a}=\dfrac{x}{y+2a}\\\downarrow\\\dfrac{19}{\frac{13}{6}a+a}=\dfrac{x}{\frac{13}{6}a+2a}\\\\\dfrac{19}{\frac{13}{6}a+\frac{6}{6}a}=\dfrac{x}{\frac{13}{6}a+\frac{12}{6}a}\\\\\dfrac{19}{\frac{19}{6}a}=\dfrac{x}{\frac{25}{6}a}\ \ \ \ |\dot a\neq0\\\\\dfrac{19}{\frac{19}{6}}=\dfrac{x}{\frac{25}{6}}\\\\19\cdot\dfrac{6}{19}=x\cdot\dfrac{6}{25}\\\\6=\dfrac{6x}{25}\ \ \ |\cdot25\\\\6x=6\cdot25\ \ \ |:6\\\\x=25$
