Answer:A Black dogs Step-by-step explanation: First do the ratio for brown dogs to black dogs it is 5:10. Then you look at the question and it asks for every 1 brown dog there are 2____ dogs, so if you look at the first ratio we made; 5:10 the 5 multiplied by 2 equals 10. So if the second ratio has to be 1:2, 5:10 is equal to 1:2 so it is correct. Hope this helps! Sorry if wrong!

Find the first three terms of the series represented by the formula 3(- 2)(n - 1).
enyata [817]

Answer:

0, - 6, - 12

Step-by-step explanation:

To find the first 3 terms, substitute n = 1, 2, 3 into the formula

a₁ = 3(- 2)(1 - 1) = 3 × - 2 × 0 = 0

a₂ = 3(- 2)(2 - 1) = 3 × - 2 × 1 = - 6

a₃ = 3(- 2)(3 - 1) = 3 × - 2 × 2 = - 12

First 3 terms are 0, - 6, - 12

Find all real solutions of the equation. (if there is no real solution, enter no real solution.) 35x2 12x − 36
solmaris [256]
Important:  35x2 12x − 36 is not an equation; to obtain an equation, you must set <span>35x2 12x − 36 = to 0:

</span><span>35x^2 + 12x − 36 = 0.  Also, "the square of x" must be represented by "x^2," and you must insert either the + or the - sign in front of the term 12x.

I am assuming that you meant   </span>35x^2 + 12x − 36 = 0.

If that is indeed the case, then a = 35, b = 12 and c = -36

and the discriminant is b^2 - 4ac, or (12)^2 - 4(35)(-36) = 5184.

Since the discriminant is positive, this equation has 2 real, unequal solutions.  They are
        -12 plus or minus sqrt(5184)
x = -----------------------------------------
                         2(35)
