Determine the maximum number of zeros. Then, determine the x-intercepts of the function. x^3-3x^2-22x+24

JulijaS [17]

Answer:

Three zeros $x=-4,\ x=1,\ x=6$

x-intercepts: (-4,0), (1,0), (6,0)

Step-by-step explanation:

Plot the graph of the function $y=x^3-3x^2-22x+24$ on the coordinate plane. This graph intersects the x-axis at three different points (see attached diagram):

(-4,0);
(1,0);
(6,0).

This means $x=-4,\ x=1,\ x=6$ are zeros of the function $y=x^3-3x^2-22x+24$

A pentagon has angle measures of 12x°, 7x°, 16x°, 9xº, and 10x°. Find the value of x.

8_murik_8 [283]

Answer:

Step-by-step explanation:

The sum of all the interior angles of a pentagon is 540°

So...

540 = 12x + 7x + 16x+ 9x + 10x

Combine like terms:

540 = 12x + 7x + 16x+ 9x + 10x

540 = 54x

Divide by 54 on both sides:

540 = 54x

/54 /54

10 = x

Hope this helps :)

Use substitution to solve each system of equations: x=y+6 x+y=10

Fittoniya [83]

= (y+6) +y =10
= 2y + 6 = 10
= 2y = 4
Y= 2

In the right triangle shown, <B=60° and AB=18. How long is AC?

Naily [24]

Answer:

18√3

Step-by-step explanation:

tan Ф = opposite/adjacent

tanФ = AB/AC

tan 60 = AC/AB

Tan 60 =√3 AB=18

√3=AC/18

AC=18√3

2m·4b−3a·2n−0.2b·5m+n·5a−5bm+8an

cupoosta [38]

Answer:

2bm + 7an

Step-by-step explanation:

Multiply.

8bm - 6an - bm + 5an - 5bm + 8an

Combined like terms:

8bm - 6an - bm + 5an - 5bm + 8an

= 2bm + 7an
