1. If a function f(x) is shifted to the left one unit, what function represents the transformation?
Vaselesa [24]
<span><u><em>The correct answers are: </em></u>
1) A;
2) A;
4) D 
3 cannot be done because the graph is not shown.

<u><em>Explanation:</em></u><span><u><em> </em></u>
1) Shifting a graph to the left, we would normally think of subtracting 1 from the function. However, horizontal translations are the opposite; left means adding 1 to x, while right means subtracting 1 from x.

2) A reflection in the x-axis means the y-coordinate will be negated (the opposite sign). This means that g(x)=-f(x)=-(x^2+5=-x^2-5.

4) To perform a vertical stretch of a function, we multiply by the factor; this gives us y=6x.</span></span>

Find the missing endpoint if S is the midpoint of RT <br><br>R(-9,4) and S(2,-1) ; Find T​
liraira [26]

Answer:

T is at (13,-6)

Step-by-step explanation:

x-coordinate of T: from -9 to 2, there's 11 units, so you add 11 to 2 to find the x-coordinate of T, which is 13.

y-coordinate of T: from 4 to -1 there's -5 units, so you subtract 5 from -1 to find the y-coordinate of T, which is -6.

Answer:

Read explanation

Step-by-step explanation:

Wow I'd love to go to that store of yours! :P Anyways if you were asking for the new discounted price I solved this equation: 12*0.8 and got $9.60. But if it was asking for <em>how </em> <em>much </em>was discounted, I would do 12*0.2 and $2.40.

The first three terms in the binomial expansion of (a+b)^n in ascending powers of b, are p,q and r respectively. show that q^2/p
katen-ka-za [31]

First 3 terms are a^2 + n a^(n-)1 b + n(n-1)/2 * a^(n-2) b^2


So q^2 / pr = (n^2 * a^(2n-2) * b^2 ) / (1/2 * a^n * (n(n-1) * a^(n-2) * b^2 )


= n^2 * a^2n-2 * b^2

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

1/2 n(n-1) * a^(2n-2) * b^2


= 2n / n - 1 as required


given p = 4, q=32 and r = 96:-


32^2 / 4*96 = 2n / n-1

2n / n-1 = 8/3

6n = 8n - 8

2n = 8


n = 4 answer
