Answer:
a) x = {-1, 3, 4}
b) (0.472, 13.128)
c) (3.528, -1.128)
d) x < 0.472 U x > 3.528
e) 0.472 < x < 3.528
Step-by-step explanation:
This is a cubic (odd degree) function with a positive leading coefficient, so it will be increasing until the first turning point, and after the last turning point. It will be decreasing between the turning points.
a) A graph shows the zeros to be x = -1, x = 3, x = 4.
b) A graph shows the local maximum to be approximately (0.472, 13.128). The x-coordinate of this point is exactly 2-√(7/3).
c) The local minimum is about (3.528, -1.128). Its x-coordinate is exactly 2+√(7/3).
d) As stated above, the increasing intervals are (-∞, 0.428) ∪ (3.528, ∞).
e) The decreasing interval is (0.428, 3.528).

Additional comments
The sum of odd-degree term coefficients is the same as the sum of coefficients of even-degree terms, so you know one of the roots is -1. Factoring that out gives the quadratic x^2 -7x +12 = (x -3)(x -4), so the other two roots are 3 and 4.
The derivative is 3x^2 -12x +5 = 3(x -2)^2 -7, so its roots (turning points of f(x)) are 2±√(7/3).
I find a graphing calculator can show me the roots and turning points easily.

1. A slice is being made to a cube. For each slice—
• Describe the two-dimensional figure resulting from the described slice. Use the specific name when possible.
• Determine whether a different slice can produce a congruent two-dimensional figure. If so, describe or sketch an example of the slice. If not, explain why not.
(a) a slice parallel to the base
(b) a slice that contains and
(c) a slice that contains and vertex F
Answers
(a.) A slice parallel to the base would result in two rectangular prisms, as opposed to a cube now. These two rectangular prisms would be congruent to each other as it is a perfect slice through the middle.
(b) A slice that contains and AE and DH will make a slanted cube, meaning it will turn into a cubic pyramid.
(c.) A slice that will contain and vertex F will make the cut the figure in half going slanted. They will technically be congruent, although there is no name for this figure.

Midpoints calculated, plotted and connected to make the triangle DEF, see the attached.
D= (-2, 2), E = (-1, -2), F = (-4, -1)3.
As per definition, midsegment is parallel to a side.
Parallel lines have same slope.
Find slopes of FD and CB and compare.
m(FD) = (2 - (-1))/(-2 -(-4)) = 3/2m(CB) = (1 - (-5))/(1 - (-3)) = 6/4 = 3/2As we see the slopes are sameFind the slopes of FE and AB and compare.
m(FE) = (-2 - (- 1))/(-1 - (-4)) = -1/3m(AB) = (1 - 3)/(1 - (-5)) = -2/6 = -1/3Slopes are sameFind the slopes of DE and AC and compare.
m(DE) = (-2 - 2)/(-1 - (-2)) = -4/1 = -4m(AC) = (-5 - 3)/(-3 - (-5)) = -8/2 = -4Slopes are same4.
As per definition, midsegment is half the parallel side.
We'll show that FD = 1/2CB
FD = [tex]\sqrt{(2+1)^2+(-2+4)^2}[/tex] = [tex]\sqrt{3^2+2^2}[/tex] = [tex]\sqrt{13}[/tex]CB = [tex]\sqrt{(1 + 5)^2+(1+3)^2}[/tex] = [tex]\sqrt{6^2+4^2}[/tex] = 2[tex]\sqrt{13}[/tex]As we see FD = 1/2CBFE = 1/2AB
FE = [tex]\sqrt{(-4+1)^2+(-1+2)^2}[/tex] = [tex]\sqrt{3^2+1^2}[/tex] = [tex]\sqrt{10}[/tex]AB = [tex]\sqrt{(-5 -1)^2+(3-1)^2}[/tex] = [tex]\sqrt{6^2+2^2}[/tex] = 2[tex]\sqrt{10}[/tex]As we see FE = 1/2ABDE = 1/2AC

The coordinates of the point which lies on the equation is A ( 3 , -4 )
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
y + 4 = 4 ( x - 3 ) be equation (1)
when x = 3 and and y = -4
Substituting the values of x and y in the equation , we get
-4 + 4 = 4 ( 3 - 3 )
0 = 4 ( 0 )
0 = 0
Therefore , the point A ( 3 , -4 ) lies in the equation
Hence , the coordinates of the point is A ( 3 , -4 )

Tuition and fees $ 25100
Room and board $ 8000
Books and supplies $ 1300
misc expenses $ 750

2 Year Community College
2 Year Community College
Tuition and fees $ 4400
Room and board $ 5000
Books and supplies $ 1100
misc expenses $ 800
Total for 1 year
4400+5000+1100+800
= $ 11300
Total for 2 years 2* 11300 = $ 22600
now given
kari will get $4500 in scholarships and grants yearly and $1500 yearly through work study program
so in total kari will get in financial aid = $6000 yearly
so in 2 years she will get total = 2*6000 = $12000 financial aid
kari's estimated cost per year = total fee of college for 1 year - total financial aid for 1 year
= $11300 - $ 6000 = $5300
Kari's estimated cost per year = $5300
then estimated cost for two years = 2* 5300 = $10600
given Kari's family will contribute $3000 yearly
so for two years Kari will get = 2*3000 = $6000 from family
If kari has 1 year to save for 1st year's contribution then
a) kari has $0 in savings
kari needs to save for year = estimated cos per year - contribution from family per year
= $5300 - $ 3000 = $2300
as kari has $0 savings so kari needs to save $2300 in 1 year
so kari needs to save an amount = 2300/12 = $191.666667 monthly
b) kari has $1000 in saving
then kari needs to save an amount for 1 year = estimated cost per year - contribution from family per year - kari's initial savings
Amount to be saved for 1 year = $5300 - $3000 - $1000
= $1300
so kari needs to save an amount of = 1300/12 = $108.3333333 monthly
c) Kari has $2000 in saving
then kari needs to save an amount for 1 year = estimated cost per year - contribution from family per year - kari's initial savings
Amount to be saved for 1 year = $5300 - $3000 - $2000
= $300
so kari needs to save an amount of = 300/12 = $25 monthly

Step-by-step explanation:
The angles inside a triangle always sum to 180°. We already have a 32° angle and a 90° - totalling 122° - and when we add x°, we'd like the sum to be 180°. So x must be 180 - 122 = 58.
Answer:
58
Step-by-step explanation:
The total should be 180 degrees. We know the the top angle is 32 degrees and the bottom left is 90 degrees because it has a square there. So 32+90=122. If we subtract 122 from 180 we are left with 58 degrees so x=58
