Write a quadratic function (f) whose zeros are −8 and 2.

1 answer:

6 0

$\bf x=-8,2\quad 
\begin{cases}
x=-8\implies &x+8=0\\
x=2\implies &x-2=0
\end{cases}
\\\\\\
(x+8)(x-2)=\stackrel{original}{polynomial}\implies x^2+6x-16=y$

The complement of an angle is $5^{\circ}$ more than four times the angle. what is the number of degrees in the measure of the an

Anna11 [10]

Answer:

17°

Step-by-step explanation:

Let x represent the measure of the angle.

(90 -x) = 5 + 4x . . . . the complement is 5° more than 4 times the angle

85 = 5x . . . . . . . . . . add x-5 to both sides

17 = x . . . . . . . . . . . . divide by 5

The measure of the angle is 17°.

Sebastian solved the radical equation y + 1 = but did not check his solution. (y + 1)2 = y2 + 2y + 1 = –2y – 3 y2 + 4y + 4 = 0 (

Softa [21]

Answer:

There are no true solutions to the equation.

Step-by-step explanation:

The correct equation is

$y+1=\sqrt{-2y-3}$

Solve for y

squared both sides

$(y+1)^2=(-2y-3)$

$(y^2+2y+1)=(-2y-3)$

$y^2+2y+1+2y+3=0$

$y^2+4y+4=0$

$(y+2)(y+2)=0$

$y=-2$

Verify

substitute the value of y in the original expression

$-2+1=\sqrt{-2(-2)-3}$

$-1=1$ ----> is not true

therefore

There are no true solutions to the equation.

What are the zeros of the function y = x2 + 10x – 171, and why?

vagabundo [1.1K]

To find the zeros, you have to factor the equation.
y=(x+19)(x-9)
This is because 19*-9=-171 and 19-9=10.
Now to make x=0, you have to make the equation
x+19=0
and x-9=0
To solve, isolate x on both equations.
This makes x=-19 and x=9.

Judi is making a rope ladder. she uses 1/2 yard of rope for each step. how many steps can she make with 6 yards of rope?

ddd [48]

12 steps for this problem.

In reality a rope ladder is actually not just rope for the steps but ropes for the sides too
