Greetings.

The answer is

a = determines the shape of parabola (upward, downward, narrow or wide)

h = determines the transformation of the graph for x-axis (For example, (x+1)², the graph would move from x=0 to x=-1

k = determines the transformation of the graph for y-axis. (For example, x²+1, the graph would move from y = 0 to y = 1.

Step-by-step explanation:

this is a set problem (mathematical set)

30 students played soccer

9 students played cricket and soccer

x students played neither cricket nor soccer

3x students played cricket only.

we can see that in the first set 21 appears and in the middle of the set 9 because it says 30 students played soccer adding x and 3x we have the following formula

30 + x + 3x = 50 where x is equal to 5 then ask us Determine the number of students who played cricket. then the value would be 3x + 9 = (3x5) + 9 = 24

Find BC if B(8,-7) and C1-4,-2).

Alika [10]

Using distance formula :

$\sqrt{(x_2 - x_1) {}^{2} + (y_2 - y_1) {}^{2} }$

$\sqrt{(8 - ( - 4)) {}^{2} + ( - 7 - ( - 2)) {}^{2} }$

$\sqrt{(12) {}^{2} + ( - 5) {}^{2} }$

$\sqrt{144 + 25}$

$\sqrt{169}$

Change the decimal 0.0112 to a fraction. A. 112/10,000 B. 112/100 C. 112/100,000 D. 112/1,000

ehidna [41]

The answer would be A. 112/10,000.

The answer would be that because: If we do 0.1001, it wouldn't be 112/100 or 112/1,000, and 112/100,000 is too big.

Hope this helped! c:
