Answer 2

Here's a strange fact I recently found out:

"Scientists have long known that Africa is the cradle of human civilization​. There, our ancestors shed most of their body hair around 2 million years ago, and their dark skin protected them from skin cancer and other harmful effects of UV radiation. When humans began leaving Africa 20,000 to 50,000 years ago, a skin-whitening mutation appeared randomly in a sole individual, according to a 2005 Penn State study.  That mutation proved advantageous as humans moved into Europe. Why? Because it allowed the migrants increased access to vitamin D, which is crucial to absorbing calcium and keeping bones strong. "

Answers

Answer:

Step-by-step explanation:

if I'm wrong please let me know

Answer: C

Step-by-step explanation:

The domain is all real values of x such that x is less than or equal to zero.

If x is greater than  zero then all the positive numbers  will make the number in the square root negative and that will  become an imaginary number.

If x is zero  then the number in the number will be 0 and find the square root of 0 is possible.

Samuel bought 3 tires for $79.95 each and some rims for $59 each. He
spent a total of $534.85. Which equation could be used to find the
number of rims, r, Samuel bought?

Answers

Answer:

(3)79.95 + 59r = 534.85

Step-by-step explanation:

524.85= 79.95(3) + 59r

I put $524.85 to the left of the equal sign because that is the total amount spent
Then I multiplied $79.95 by three. This is because he bought 3 tires, each for $79.95
I also multiplied 59 and r, because Samuel bought r number of rims, each for $59
Finally, I added both parts of the equation together because the three tires plus the r rims together cost a total of $534.85

In the figure, the circle A with x passes through the centre y of the circle B is x^2+ y^2-4x+6y-12=0 and coordinates of x are (-4,5) then find the equation of circle A.​

Answers

Answer: A: (x + 4)² + (y - 5)² = 8

Step-by-step explanation:

The equation of a circle is: (x - h)² + (y - k)² = r²     where

(h, k) is the center of the circler is the radius of the circle

To find the equation of circle A, we need (h, k) and r².

It is given that (h, k) = (-4, 5)

The distance between the center of circles A and B is the radius of circle A.

Let's find the center of circle B by completing the square:

x² - 4x + ____ +  y² + 6y + _____ = 12 + ____ + _____

     ↓                            ↓      

  h = -4/2                    k = 6/2

  h = -2                       k = 3              →  Circle B has center (-2, 3)

Now let's find the distance between the center of circles A and B:

[tex](r_A)^2=d^2=(x_A-x_B)^2+(y_A-y_B)^2[/tex]

                = (-4 - (-2))² + (5 - 3)²

                =     (-2)²     +     2²

                =       4        +     4

                = 8

Now we have the the center (h, k) and the r² for circle A:

(h, k) = (-4, 5) and r² = 8   →    (x + 4)² + (y - 5)² = 8

James is 6 times older than his friend Zach, if Zach added 8 to his age and multiplied this sum by 3.
Write an equation that can be used to solve for Zach's age in the box below, use Z as the variable.

Answers

Given that:

James is 6 times older than his friend Zach, if Zach added 8 to his age and multiplied this sum by 3.

Step-by-step explanation:

Let the Zach's age be Z years.

6 times older than Zach = 6Z

Zach added 8 to his age and multiplied this sum by 3 = 3(Z+8)

Now,

[tex]6Z=3(Z+8)[/tex]

[tex]6Z=3Z+24[/tex]

[tex]6Z-3Z=24[/tex]

[tex]3Z=24[/tex]

Divide both sides by 3.

[tex]Z=\dfrac{24}{3}[/tex]

[tex]Z=8[/tex]

Therefore, the required equation is [tex]6Z=3(Z+8)[/tex] and Zach's age is 8 years.

Which expressions are equivalent to 5^12 x 5^8? A. 25^20 B. (25^5)^4 C. (5^3 x 5^2)^4 D. (5^5)^4

Answers

Hey there! I'm happy to help!

When multiplying numbers with exponents, all you do is add the exponent numbers, so 5^12×5^8=5^20.

A is not equal to this.

B is also not equal to this. B is 25^20.

C is  wrong as well. It is 5^5.

This leaves us with D, which does evaluate to 5^20. If you raise a power to a power you multiply the exponent numbers, and 5(4)=20.

The answer is D. (5^5)^4.

Have a wonderful day! :D

5^12 * 5^8

5^12+8

5^20

The only option that is equal to that is D.

(5^5)^4

  (c) 378 +2A -2B

Step-by-step explanation:

Water flowing in adds to the amount in the reservoir. Water flowing out subtracts from the amount in the reservoir.

__

(a) 412 + A - B . . . . at the end of January

__

(b) Flowing in was (A -20), flowing out was (B +14). In February, we start with the amount at the end of January.

  (412 +A -B) +(A-20) -(B +14)

Which of the following graphs represents the solution set for the inequali
-35-2x +1 <11

Answers

Answer:

You did not give the options, so i just will graph it.

The inequality is:

-35 - 2*x + 1 < 11.

Now we would want to isolate the x in one side, so we can start by adding 35 in both sides.

(-35 -2*x + 1) + 35 < 11 + 35

-2x + 1 < 46

now we can subtract 1 in both sides:

-2x + 1 - 1 < 46 - 1

-2x < 45

Now we can divide by -2, remember that if we multiply or divide by a negative number, then the "direction" of the sign changes.

(-2x)/-2 > 45/-2

x > -22.5

Then the graph of the set is an open dot at the point x = -22.5 (this means that the set does not include this point) and a line that extends to the right. (Extends to the right because x is larger than -22.5)

Below is an example of how to draw the graph that represents the set of solutions.

What equation is the equation of the line, in point slope form, that has a slope of -1.8 and passes through the point (-0.5, 1.9) ?

Answers

Answer:

Third option[tex]y -1.9=-1.8(x+0,5)[/tex]

Step-by-step explanation:

Slope = -1.8

(-0.5,1.9)

[tex]m =-1.8\\(-0.5 , 1.9) = (x_1 ,y_1)[/tex]

Substitute values into point slope form

[tex]y-y_1=m(x-x_1)\\\\y -1.9=-1.8(x -(-0.5))\\\\y -1.9 =-1.8(x+0.5)[/tex]

Answer:

y − 1.9 = −1.8 (x + 0.5)

Step-by-step explanation:

select the values for a, b, and c that will make the following equation true.
ax² + bx + c = (x + 8)(x – 1)
A. a = 1
B. a = 2
C. b = -7
D. b = 7
E. c = -8
F. c = 9

Answers

Step-by-step explanation:

(x + 8)(x - 1) = x^2 - x + 8x - 8 = x^2 + 7x - 8.

Hence a = 1, b = 7, c = -8. (Options A, D and E)

Two lines are perpendicular when... the product of their slope is -1, the product of the slope is greater than 0, they have the same slope, or when the slope is undefined?

Answers

The answer is the product of their slope is -1.

First, let's break this down. Perpendicular lines are line with opposite reciprocal slopes. Opposite meaning the inverse sign and reciprocal meaning flipped.

For instance,

If a line had the slope of 5, its inverse would have a slope of -1/5.

Now, if we multiply these numbers together,

5 * -1/5 = -1

The 5's cancel out.

This works for any two perpendicular lines

Answer:

The answer is the product of their slopes is -1.
