Step-by-step explanation:

Use the Pythagorean Theorem to find the missing sides in the triangles.

c^{2} = a^{2} + b^{2}

Q2. c^{2} = 8^2 + 40^2

c^{2} = 1664

c = \sqrt{1664}

c = 8\sqrt{26}

Find the missing sides of the other triangles and figure out which ones are the same.

Q3. Do the same thing as Q2.

Apply the laws of probability and calculate the probability the offspring of the cousin marriage of 3 x 7 will have the trait. (
lilavasa [31]

Answer:

0.16

Step-by-step explanation:

The calculation of probability by applying the is shown below:-

It is evident from the pedigree that the mode of inheritance is recessive and the characteristic is recessive that's also phenotype of disease is only seen if the genotype is aa.

The genotype of 1. In pedigree Can be either AA or Aa.

The chance that the offspring of the 3\times 7 cousin marriage will have the characteristic is

= \frac{1}{6}

which gives results

= 0.16

Which of the following is the solution to the compound inequality below?<br> 3x+5 2 -1 or -2x - 725
sashaice [31]

Answer:

x= -674

Step-by-step explanation:

Solve for x and check: x + 5 = 3

Solution

Solve for x and check: - 3x = 12

Dividing each side by -3, we obtain

Another way of solving the equation

3x - 4 = 7x + 8

would be to first subtract 3x from both sides obtaining

-4 = 4x + 8,

then subtract 8 from both sides and get

-12 = 4x.

Now divide both sides by 4 obtaining

- 3 = x or x = - 3  

Solve for c: 3(x + c) - 4y = 2x - 5c

First remove parentheses.

Remember, abx is the same as 1abx.

We divide by the coefficient of x, which in this case is ab.

Find all complex solutions of 5x^2-6x+2=0.
gregori [183]
We use quadratic formula for that one
remember that √-1=i

so

for
ax^2+bx+c=0
x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}
so
given
5x^2-6x+2=0
a=5
b=-6
c=2

x=\frac{-(-6)+/-\sqrt{(-6)^2-4(5)(2)}}{2(5)}
x=\frac{6+/-\sqrt{36-40}}{10}
x=\frac{6+/-\sqrt{-4}}{10}
x=\frac{6+/-2i}{10}

x=\frac{3}{5}+\frac{i}{5}, \frac{3}{5}-\frac{i}{5}
