1 answer:

7 0

<span>Any change in nucleotide sequence may lead to mutations and thereby different types of disorders or diseases. Sickle cell, Tay Schs are some diseases caused by the change in nucleotide. A nucleotide is responsible for coding for a protein. So change will lead to failure of production of particular protein and cause for disease.</span>

So i have this promblem in it says slove for x 5 equals x -3

Allisa [31]

Answer:

x = 8

Step-by-step explanation:

Solve for x in the equation: 5 = x - 3

x - 3 = 5

Isolate x by adding 3 on both sides of the equation.

x - 3 + 3 = 5 + 3 (on left side: +3 and -3 cancel out)

x = 8

Xpand the binomial (4x + 3y)3. The coefficient of the second term in the expansion of the binomial (4x + 3y)3 is .

Ad libitum [116K]

Answer: 144

Step-by-step explanation:

The binomial is $\left( 4x+3y\right)^3$

The expansion of $\Rightarrow \left ( a+b \right )^n=^nC_0\left ( a \right )^n\left ( b \right )^0+^nC_1\left ( a \right )^{n-1}\left ( b \right )^1+^nC_2\left ( a \right )^{n-2}\left ( b \right )^2+^nC_3\left ( a \right )^{n-3}\left ( b \right )^3+\ldots$

Expansion of $\left( 4x+3y\right)^3$

$\Rightarrow ^3C_0\left ( 4x\right )^{3}\left ( 3y\right )^0+^3C_1\left ( 4x\right )^{2}\left ( 3y\right )^1+^3C_2\left ( 4x\right )^{1}\left ( 3y\right )^2+^3C_3\left ( 4x\right )^{0}\left ( 3y\right )^3$

So, the second term is

$\Rightarrow ^3C_1\left ( 4x\right )^{3-1}\left ( 3y\right )^1\\\Rightarrow ^3C_1\left ( 4x\right )^{2}\left ( 3y\right )^1$

Its Coefficient is

$\Rightarrow ^3C_1\times 4^2\times 3\\\Rightarrow 3\times 16\times 3=144$

Joshua used two wood beams, PC and QA, to support the roof of a model house. The beams intersect each other to form two similar

olga55 [171]

Because the triangles are similar, their corresponding sides will have the same ratio. Side corresponding to PQ is AC and side corresponding to RC is PR. Thus:
RC/PR = AC/PQ
5.1 / 3.4 = 4.2 / PQ
PQ = 2.8 inches
