Factor by grouping. 3x³ – 2x²–9x+6​

Answer:

The graph of the function opens downwards.

Step-by-step explanation:

The graph opens upward if the coefficient of x^2 is higher than 0.

But, the coefficient of x^2 (-3) is less than 0.

So the graph of the function opens downwards.

Answer: 24°

Step-by-step explanation:

You have the opposite, the height of the building and the adjacent, the distance from the base of the building. Opposite and adjacent mean you have to use tangent. SOHCAHTOA

Take the inverse tangent on both sides

tan(Ф) = 40/90

Ф = 24°

Answer:

1260

Step-by-step explanation:

Tents: 15×54=810

Caravans: 25×18=450

450+810=1260

Answer:

$1260

Step-by-step explanation:

Campsite Fees:

Tent - $15 (per day)

Caravan - $25 (per day)

No. of Tents and Caravans today:

Tents - 54

Caravan - 18

Total fees for Tent = 15 x 54

= $810.

Total fees for Caravan = 25 x 18

= $450.

Fees altogether for Today = Total fees for Tent + Total fees for Caravan

= $810 + $450

= $1260

[tex] Area \: of \: rhombus =96\: cm^2 [/tex]

Step-by-step explanation:

[tex] d_1= 2\times 8 = 16\: cm[/tex]

[tex] d_2= 2\times 6 = 12\: cm[/tex]

[tex] Area \: of \: rhombus =\frac{1}{2} d_1d_2[/tex]

[tex] Area \: of \: rhombus =\frac{1}{2}\times 16 \times 12[/tex]

3.865in^2

It's (the area of the square minus the area of the circle) divided by 2.

So, Area of the square is 6x6=36

Area of the circle is (pi)*(radius=3)^2=28.27

36-28.27=7.73

7.73/2=3.865in^2

Answer:

slope = 0

Step-by-step explanation:

Use formula to find the slope: m = (y2 - y1) / (x2 - x1)

Set (x1, y1) = (-7, 5)

Set (x2, y2) = (2, 5)

m = (5 - 5) / (2 - (-7))

m = (5 - 5) / (2 + 7)       FYI, negative * negative = positive

m = 0 / 9

If you plot the coordinates, they'll lie on a horizontal line. Therefore, the slope of the line is 0.

Answer:

1. P = [tex]\frac{I}{rt}[/tex]

2.  y = [tex]\frac{6 - 3x}{11}[/tex] or [tex]\frac{-3x +6}{11}[/tex]         (depending on how you want the equation arranged)

3. c = [tex]\frac{a-bd}{b}[/tex]

4 t = [tex]\frac{A - p }{pr}[/tex]

Step-by-step explanation:

1. I =Prt for P:

I = Prt                           divide both sides by rt to isolate P

P = [tex]\frac{I}{rt}[/tex]

2. 3x + 11y = 6 for y

   3x + 11y = 6                  subtract 3x from both sides

   11y = 6 - 3x                   divide both sides by 11

   y = [tex]\frac{6 - 3x}{11}[/tex] or [tex]\frac{-3x +6}{11}[/tex]         depending on how you want the equation arranged

3. a = b(c + d) for c

   a = b(c + d)                distribute b to (c+d)

   a = bc + bd                subtract bd from both sides

   a - bd = bc                 divide both sides by b

   c = [tex]\frac{a-bd}{b}[/tex]

4. A = p + prt for t

   A = p + prt                   subtract p from both sides

   A - p = prt                    divide both sides by pr

   t = [tex]\frac{A - p }{pr}[/tex]

Option B,  two variables are measured and two groups are compared

Step-by-step explanation:

In a correlation study relationship between two variable is established.

The two variables represents two group.

For instance correlation study is conducted to determine the relationship between two variables X and Y

X and Y are variable

While X represents the group "number of cars passing through a lane"

Y represents the group "width of the road".

Hence, Option B is correct

Answer:

3.5 days

Step-by-step explanation:

Given

[tex]Day\ 1 = 343\ miles[/tex]

Required

Number of days to drive 1200 miles

Represent as ratio:

[tex]Day\ 1 = 343\ miles[/tex]

[tex]Ratio = 1 : 343[/tex]

For 1200 miles

[tex]Ratio = x : 1200[/tex]

Equate both ratios

[tex]x : 1200 = 1 : 343[/tex]

Express as fractions

[tex]x/1200 = 1/343[/tex]

Multiply by 120

[tex]x/1200 *1200= 1/343*1200[/tex]

[tex]x= 3.4985[/tex]

[tex]x= 3.5[/tex] --- approximated

Answer:

y = x - 8

Step-by-step explanation:

Slope intercept form:  y = mx + b, where b is the y-intercept.

Solve the given equation for y and then compare the result with this y = mx + b:

3y = 3x - 24

Dividing all three terms by 3 yields:

y = x - 8 (answer).  The slope is 1 and the y-intercept is -8.

The slope is equal to the change in y / change in x.

The change in y is always 5 and the change in x is always 1.

So the change in y / change in x is 5/1 or 5.

The y-intercept is the value of y when x = 0.

So the value of y when x = 0 is 2.

9514 1404 393

Answer:

  1/6

Step-by-step explanation:

The slope is the ratio of rise to run.

  slope = rise/run = (6 ft)/(36 ft) = 6/36 = 1/6

Given:

The polynomial function is

[tex]F(x)=4x^3-6x^2+9x+10[/tex]

To find:

The possible roots of the given polynomial using rational root theorem.

Solution:

According to the rational root theorem, all the rational roots and in the form of [tex]\dfrac{p}{q}[/tex], where, p is a factor of constant and q is the factor of leading coefficient.

We have,

[tex]F(x)=4x^3-6x^2+9x+10[/tex]

Here, the constant term is 10 and the leading coefficient is 4.

Factors of constant term 10 are ±1, ±2, ±5, ±10.

Factors of leading term 4 are ±1, ±2, ±4.

Using rational root theorem, the possible rational roots are

[tex]x=\pm 1+,\pm 2, \pm 5, \pm 10,\pm \dfrac{1}{2}, \pm \dfrac{5}{2}, \dfrac{1}{4}, \pm \dfrac{5}{4}[/tex]

Therefore, the correct options are A, C, D, F.
