Find k and help with the equation!

<h3>Answer:   k = 6+10x</h3>

=======================================================

Work Shown:

64*4^{5x}\\\\\left(2^6\right)*\left(2^{2}\right)^{5x}\\\\\left(2^6\right)*\left(2^{2*5x}\right)\\\\\left(2^6\right)*\left(2^{10x}\right)\\\\2^{6+10x}\\\\

The result is in the form 2^k with k = 6+10x

------------------------

Explanation:

First we need to get everything as an exponential expression with a base 2.

We rewrite 64 as 2^6 and 4 as 2^2 in the second step.

In the third step, I used the rule (a^b)^c = a^{b*c} which says to multiply the exponents together. That's how I went from (2^2)^{5x} to 2^{2*5x}. Then the 2*5x in the exponent becomes 10x.

To wrap things up, I used the rule a^b*a^c = a^{b+c} which says to add the exponents when we multiply stuff of the same base together.

So heterozygous means one dominant trait and one recessive trait (Ll). Homozygous is either 2 recessive traits or 2 dominat. (in this case ll).
1.)Genotype: Ll and ll
Phenotype: 50% chance of Long pea plant, 50% chance of short.
2.) Genotype: Ww (widows peak) and ww (no widows peak)
Phenotypes: 75% chance of widows peak and 25% of no widows peak.
3.) Genotype: BB and Bb
Phenotype: 100% chance of black

If O N = 8 x − 8 , L M = 7 x + 4 , N M = x − 5 , and O L = 3 y − 6 , find the values of x and y for which LMNO must be a paralle
posledela

Answer:

x=12\\y=\frac{13}{3}


Step-by-step explanation:

For it to be a parallelogram, opposite sides have to be of same length.

  • OL = NM, and
  • ON = LM

Using the expressions given, we can make 2 equations:

<u>Equation 1:</u>

OL=NM\\3y-6=x-5\\-x+3y=1


<u>Equation 2:</u>

ON=LM\\8x-8=7x+4\\


<em>Solving equation 2, we have x:</em>

8x-8=7x+4\\8x-7x=4+8\\x=12

<em>Plugging this value of x into equation 1, we can solve for y:</em>

-x+3y=1\\-(12)+3y=1\\-12+3y=1\\3y=13\\y=\frac{13}{3}

So,

x=12\\y=\frac{13}{3}

I need help ASAP can someone please help me right away​.​
lisov135 [29]

Answer:

45 degrees

Step-by-step explanation:

Think of this web as a circle. This circle is divided into 8 equal pieces.

A circle has 360 degrees in it. If we divide 360 by 8, we get 45. This means that each wedge is 45 degrees, which means that in order to rotate the image to look the same, we must rotate it by 45 degrees.

WILL GIVE A BRAINLEST<br><br> What is the value of [3.6]<br> 3<br> 3.5<br> 3.6<br> 4
ziro4ka [17]

Answer:

A) 3

Step-by-step explanation:

The notation f(x)=[x] represents the greatest integer function, with the integer being less than or equal to x.

Since we have to find the nearest integer smaller than the given number, we can say that greatest integer function always rounds down its input to the nearest integer.

We have to find the value of [3.6]. So we have to round down 3.6 to its nearest integer, which will be 3.

Therefore, the option A gives the correct answer.
