The number of terms in the binomial expansion of (3x-5)^9 is 10
Mkey [24]2 years ago
6 0

Answer: 10

Step-by-step explanation:

We know that in the binomial expansion of (a+b)^n, the total number of terms = n+1

For the binomial expansion of (3x + 5)^9 , n= 9

Then, the  total number of terms in binomial expansion of (3x + 5)^9 will be :-

n+1=9+1=10

Hence, there are 10  terms are in the binomial expansion of (3x +5)^9.

Answer:

\sf A . \sf \frac{3}{-7}

\sf E. \sf -( \frac{-3}{-7} )

This above options makes the expression true.

  • The negatives above can be distributed up as well, which happened in A.
  • In E, when the negatives inside the bracket cancels out, the negative outside the brackets multiplies and makes the expression true.
  • In B the expression turns positive, thus false same happens with C and D

Hi,
To find K you will pick a value from the x and then the corresponding Y value. Then we will plug it into the equation that is given y=Kx

Here:
X=25 Y=160
160=k25
(Divide both sides by 25 to isolate K)
K=6.5

Then plug K value into equation
Y=6.5X

Then if you want to check if that is correct you can pick a different point on the table and plug that into the equation to see if you get the same value.

Check:
X=50

Y=6.5x50
Y=320

The equation line l is given by the equation y= 7/4x+3. line m goes through the point ( –1,4) and is perpendicular to line l whi
mr_godi [17]

We determine line m as follows:

*First, by theorem we have the following:

m_1=-\frac{1}{m_2}

Here m1 & m2 are the slopes of two perpendicular lines. For all lines that are perpendicular that is true, so we calculate the slope of line m using the slope of the function given [Which has a slope of 7/4]:

m_1=-\frac{1}{\frac{7}{4}}\Rightarrow m_1=-\frac{4}{7}

So, the slope of line m is -4/7. Now, using this slope and the point (-1, 4) we replace in the following expression:

y-y_1=m_1(x-x_1)

Here x1, y1 & m1 are the x-component of the point, the y-component of the point, and the slope of the line respectively, so we replace and solve for y:

y-4=-\frac{4}{7}(x-(-1))\Rightarrow y-4=-\frac{4}{7}x-\frac{4}{7}\Rightarrow y=-\frac{4}{7}x+\frac{24}{7}

And that last function of y is the line m.
