Consider the quadratic function f(x) = –2x2 5x – 4. the leading coefficient of the function is?

evablogger [386]

Answer:

$\text{-2 is the leading coefficient of the quadratic equation }f(x)=-2x^2+5x-4$

Step-by-step explanation:

Given the quadratic function

$f(x)=-2x^2+5x-4$

we have to find the leading coefficient of given quadratic equation.

$\text{The general form of quadratic equation is }ax^2+bx+c=0$

The coefficient of $x^2$ i.e a is known as the leading coefficient.

Comparing given equation with the standard equation, we get

a=-2

$\text{Hence, -2 is the leading coefficient of the quadratic equation }f(x)=-2x^2+5x-4$

5. Find JK to the nearest whole number. A

pentagon [3]

Answer:

JK ≈ 63 units

Step-by-step explanation:

Using the sine ratio in the right triangle

sin44° = $\frac{opposite}{hypotenuse}$ = $\frac{JK}{JL}$ = $\frac{JK}{90}$ ( multiply both sides by 90 )

90 × sin44° = JK , that is

JK ≈ 63 ( to the nearest whole number )
