1. Right

2. Right

3. Right

4. Right

5. Right

6. Right

7. Its not properly visible sorry for this.

8. Its wrong

$(\frac{1}{3} ) {}^{2} = \frac{1}{9}$

9. Right

10. Its wrong

$0.5 {}^{3} = 0.125$

11. Right

12. Its wrong.... Bcz square of minus is plus

$- 9 {}^{2} = 81$

13. Right

14. According to the BODMAS rule..

$15 - 7 \times 2 + {2}^{3}$

$15 - 14 + 8$

$1 + 8 = 9$

15.

$(11 - 8) {}^{2} - 2 \times 6$

$3 {}^{2} - 12$

$9 - 12 = - 3$

16.

$12 + \frac{ {9}^{2} }{3}$

$12 + \frac{81}{3}$

$12 + 27 = 39$

Use the parabola tool to graph the quadratic function. f(x)=2x^2 +12x+16 Graph the parabola by first plotting its vertex and the

givi [52]

(-3, -2) is the vertex.

You can find this by plugging into -b/2a to find the x value and using the x value to find the y value.

And another spot on the vertex would be (0, 16), which is the y intercept.

Write the following number as ratios of integers

s2008m [1.1K]

Our goal here is to somehow "surgically remove" the repeating part of the number, so let's start by putting the original value in a variable and messing around with it a bit.

We'll let $x=7.\overline{6}$ . We want to cut the $0.\overline{6}$ bit off completely, so let's create the scalpel that'll let us do that. If $x=7.\overline{6}$ , then we can also say that $10x=76.\overline{6}$ . Maybe I was lying a bit: the $x$ is our real scalpel here, and $10x$ is where we'll be making the cut. Mathematically, a "cut" is almost always shorthand for subtraction, so let's see what our operation (cutting $x$ off of $10x$ ) leaves us with:

$10x-x=76.\overline{6}-7.\overline{6}\\9x=69$

The operation was a success! We can now simply divide either side by 9 to find $x = 69/9$ , which, when reduced by dividing the numerator and denominator by 3, gives us $x=23/3$
