Answer:

- 3 $x^{4}$ + 15x² - 3x

Step-by-step explanation:

Given

(5 $x^{4}$ - 3x + 8x²) - (8 $x^{4}$ - 7x²)

Remove the parenthesis on first and distribute second by - 1

= 5 $x^{4}$ - 3x + 8x² - 8 $x^{4}$ + 7x² ← collect like terms

= - 3 $x^{4}$ + 15x² - 3x ← in standard form

What are the zeros of the quadratic function f(x) = 2x2 + 16x – 9?

Aleksandr-060686 [28]

Answer:

The zeros of the function are -0.488 and -7.39

Step-by-step explanation:

Given the quadratic function

f(x) = 2x²+16x-9

The zeros of the function is gotten at when f(x) = 0

2x²+16x-9 = 0

Using the general equation

x = -b±√b²-4ac/2a

From the equation, a = 2, b = 16 and c= -9

x = -16±√16²-4(2)(-9)/2(2)

x = -16±√256-72/4

x = -16±√184/4

x = -16+13.56/4

x = -16+13.56/4 and -16.13.56/4

x = --2.44/5 and -29.56/4

x = -0.488 and -7.39

The Frostburg-Truth bus travels on a straight road from Frostburg Mall to Sojourner Truth Park. The mall is 3 miles west and 2 m

Verizon [17]

To start, write your locations as points, with north and south being positive and negative y respectively and east and west being positive and negative x respectively. Doing this gives us the mall at (-3,-2) and the park at (4,5). Now, we use our distance formula $( \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 } )$ to solve for the unknown distance. Plugging in with the park values as our second values and our mall values as our first values (as well as with our unknown distance as d), we get $d= \sqrt{(4-(-3))^2+(5-(-2))^2} = \sqrt{(7)^2+(7)^2} = \sqrt{49+49} = \sqrt{98}$ . This square root can be rounded to 9.9 miles.
