What is a coefficient?

1 answer:

4 0

"A number used to multiply a variable.
Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient.

Variables with no number have a coefficient of 1.
Example: x is really 1x.

<span>Sometimes a letter stands in for the number. </span>
Example: In ax2<span> + bx + c, "x" is a variable, and "a" and "b" are coefficients."

hope this helps you!

Take into account the length of the right side of the figure is 10. Moreover, x is the hypotenuse of a right triangle. To find the value of x, use the sine function:

cos 45 = opposite side/hypotenuse

cos 45 = 10/x solve for x

x = 10/cos 45

x = 10/0.707

x = 14.14

with the previous value of x, you can find y. Again, consider the right triangle right side. x is the hypotenuse. Use the Pythagorean theorem to find y:

x² = 10² + y² solve for y and replace x

y² = x² - 10²

y² = (14.14)² - 100

y² = 200 - 100

y² = 100 apply square root both sides

y = 10

Hence, the values of x and y are 14.14 and 10 respectively

Simplify 13 over the quantity of negative 3 plus 2i.

A complex number in the denominator is eliminated by multiplying the fraction by 1 in the form of the conjugate of that denominator divided by itself.

$\dfrac{13}{-3+2i}=\dfrac{13}{-3+2i}\cdot \dfrac{-3-2i}{-3-2i}=\dfrac{13(-3-2i)}{(-3+2i)(-3-2i)}\\\\=\dfrac{13(-3-2i)}{(-3)^2-(2i)^2}=\dfrac{13(-3-2i)}{9+4}\\\\=-3-2i$
