<u>Answer:</u>

The correct option is 4.

<u> Solution: </u>

The degree of the polynomial function is 3, hence it will have 3 solution.

The root of the equation of f(x) are the values where the function f(x) crosses the x axis. In this case it is given that the roots of the function f(x) =0 are -2, 0, 3 .

So, the function will touch the x axis in three points which are -2. 0 and 3. The equation can be $(x+2)\timesx\times(x-3)$ . Here in the given options, the $4^{th}$ option the line is crossing on these three points. So, the correct option is 4.

On a particular day, the wind added 4 miles per hour to Alfonso's rate when he was cycling with the wind and subtracted 4 miles

rjkz [21]

Ok so R=alfonso's rate
w=wind rate=4

d=rt

with wind rate is R+4
agaoins wind rate is R-4

with wind distance is 34
against is 18 miles
time is same

34=(r+4)t
18=(r-4)t

34=(r+4)t
divide both sides by (r+4)
34/(r+4)=t

18=(r-4)t
divide both sides by (r-4)
18/(r-4)=t

18/(r-4)=t
34/(r+4)=t

set equal to each other

18/(r-4)=34/(r+4)
multiply both sides by (r-4)(r+4)
18(r+4)=34(r-4)
distribute
18r+72=34r-136
subtract 18r from both sides
72=16r-136
add 136 to both sides
208=16r
divide both sides by 16
13mph

answer is 13mph with no wind

Find the common difference of the sequence shown 1/6,1/3,1/2,2/3,......

tekilochka [14]

Answer:

Common Difference(d) is

$d=\frac{1}{6}$

Step-by-step explanation:

Given sequence is :

$\frac{1}{6}, \frac{1}{3} ,\frac{1}{2} ,\frac{2}{3} .........$

If a sequence has a constant common difference throughout the sequence, then the sequence is called Arithmetic Progression.

Considering a sequence:

$a_1,a_2,a_3,a_4..........\\$

$a_2-a_1=a_3-a_2=a_4-a_3=a_n-a_n_-_1=d$

where 'd' is the common difference of the A.P.

Similarly, finding the common difference of the given sequence.

$\frac{1}{3} -\frac{1}{6}= \frac{1}{2}- \frac{1}{3}=\frac{2}{3} - \frac{1}{2}=d\\$

$d=\frac{1}{3}-\frac{1}{6}=\frac{(2)(1)-(1)(1)}{6}=\frac{1}{6}$

$d=\frac{1}{6}$

Common Difference(d) is

$d=\frac{1}{6}$

•How do you use the distance formula and slope formula to classify a triangle?

trasher [3.6K]

To classify the angle of a triangle (acute, obtuse, or right), you can use slope formula to see if the slopes are perpendicular. If so, it is a right triangle. The distance formula can be applied to figure out whether the triangle is isosceles, equilateral, or scalene. if the triangle is isosceles, then two of the sides will be the same length and one side will be of a different length. If the triangle is equilateral, then all sides will be of the same length. If the triangle is scalene, then all side will be of different lengths.

What is 5/8 as a decimal and a percent?

Anna [14]

To find the decimal divide the numerator by the denominator so
5/8=0.625 therefore as a decimal 5/8 =0.625
To find its percentage divide the numerator by the denominator and multiply by 100 so
5/8 *100=62.5 therefore as a percentage 5/8 is 62.5%
