Find the fifth term of (2x + y)^10

mamaluj [8]

$T_r={n \choose r-1}a^{n-(r-1)}b^{r-1}\\T_5={10 \choose 5-1}(2x)^{10-(5-1)}y^{5-1}\\T_5={10 \choose 4}(2x)^6y^{4}\\T_5=\frac{10!}{4!6!}64x^6y^{4}\\T_5=\frac{7\cdot8\cdot9\cdot10}{2\cdot3\cdot4}64x^6y^{4}\\T_5=7\cdot3\cdot10\cdot64x^6y^{4}\\T_5=13440x^6y^4$

An 8 ounce mug requires 0.3 cup of hot cocoa mix. How much hot cocoa mix is needed for a 12 ounce mug?

8090 [49]

Answer:

0.45

Step-by-step explanation:

Step 1:

$\frac{8}{0.3} =\frac{12}{x}$

Step 2:

8 · x = 0.3 · 12

8x = 3.6

Last Step: Divide both sides by 8 to isolate the value x

In parallelogram ABCD, point M is the midpoint of the side BC , point O is the intersection point of the segment AM and diagonal

Greeley [361]

Answer: BO:OD = 1:2

Step-by-step explanation:

Here, ABCD is parallelogram, point M is the midpoint of the side BC , point O is the intersection point of the segment AM and diagonal BD.

Let N is the mid point AB ⇒ AN=NB or 2.BN=DC. ( because AB=DC)

And join Points N and C. (by construction)

Then, In triangles NOB and DOC,

∠NOB=∠DOC ( vertically opposite angles)

And, ∠OBN = ∠ODC ( By the property of interior alternative angles by same transversal)

Thus, By the property of similarity,

$\triangle NOB\sim \triangle DOC$

Therefore, $\frac{OB}{OD} = \frac{BN}{DC}$ = $\frac{BN}{2BN} = \frac{1}{2}$
