A^2 + b^2 = c^2


With this, we can tell that

9*9 + 12*12 = X^2


81 +144 = X^2

225 = X^2

(take the square root of 225)

15 = X

therefore, option B is your answer :)

Which values for a and b make the statement (a+6) (b-1)=0 true?
alexdok [17]

Answer:

The answers A, B, and C all work for this problem. The answer D is the only one that does not.

Step-by-step explanation:

When looking at two parenthesis being multiplied together and being equal to 0, we know that at least one of the parenthesis must be equal to 0 for it to be true. In A and C, the first parenthesis will be equal to 0 due to a = -6.

(a + 6)

(-6 + 6)

(0)

And in B, we can see that the second parenthesis would be equal to 0 due to b = 1

(b - 1)

(1 - 1)

(0)

Now we can try the D options, but will note that they do not work for either parenthesis.

(a + 6)(b - 1)

(0 + 6)(0 - 1)

(6)(-1)

Plot -2 on the number line below
IrinaK [193]

Answer: 8,263

Step-by-step explanation: The number 8,263 lies between 8,260 and 8,270 on the number line.  Label all the other tick marks between 8,260 and 8,270. Is 8,263 closer to 8,260 or 8,270 on the number line? Which hundred is 8,263 nearest to on the number line?  Plot 8,200 and 8,300 on the two outermost spots on the number line below.  Then plot 8,263 to prove your answer. Which thousand is 8,263 nearest to on the number line?  Plot 8,000 and 9,000 on the two outermost spots on the number line below.  Then plot 8,263 to prove your answer. 8,263 is closest to 8,260.  In other words, 8,263 rounded to the nearest ten is 8,260. 8,263 is closest to 8,300.  In other words, 8,263 rounded to the nearest hundred is 8,300. 8,263 is closest to 8,000.  In other words, 8,263 rounded to the nearest thousand is 8,000.

Given the function, g(x)=5x^5/x^3-2x+1, choose the correct horizontal asymptote. none y = 0 y = 1 y = 3
viktelen [127]

Answer:  NONE

<u>Step-by-step explanation:</u>

Consider that m is the degree of the numerator and n is the degree of the denominator.

The rules for horizontal asymptote (H.A.) are as follows:

If m > n   then no H.A. (use long division to find the slant asymptote)

If m = n   then H.A. is y = leading coefficient of numerator/leading coefficient of denominator

If m < n   then H.A. is y = 0

Given: g(x) = 5x⁵/(x³ - 2x + 1)

--> m = 5, n = 3

Since m > n then there is no H.A.
