s = ut +  \frac{1}{2} a {t}^{2}  \\  \\  \frac{1}{2} a {t}^{2}  = s  - ut \\  \\ a = (s  - ut) \:  \div (\frac{1}{2}  {t}^{2}) \\  \\ a = (s  - ut) \:   \times ( \frac{2}{ {t}^{2} } ) \\  \\ a =  \frac{2s - 2ut}{{t}^{2}}  \\  \\ a =  \frac{2s}{{t}^{2}} -  \frac{2ut}{{t}^{2}}   \\  \\  \\ a =  \frac{2s}{{t}^{2}} - \frac{2u}{t}

I hope I helped you^_^

Hello there!

Number 1 is C (11, 4) Image is below

I don't know number 2, so so sorry!


Number 3 is A. 36 The formula for perimeter of a rectangle is (2 * base) + (2 * height)
The base = 13
The height = 5

(5 * 2) + (13 * 2)

10 + 26 = 36


Number 4 is 23 units.

Solve the quadratic equation 4x2 − 121 = 0. Verify your answer using a difference-of-squares factoring method.
Alenkasestr [34]

Answer:

Option d) is correct

That is x equals plus or minus start fraction 11 over two end fraction

Step-by-step explanation:

Given quadratic equation is 4x^2-121=0

To write the given quadratic equation by using a difference-of-squares factoring method:

4x^2-121=0

The above equation can be written as

4x^2-11^2=0

(2x)^2-11^2=0

The above equation is in the form of difference-of-squares

Therefore the given quadratic equation can be written in the form of difference-of-squares

by factoring method is (2x)^2-11^2=0

(2x+11)(2x-11)=0 (which is in the form a^2-b^2=(a+b)(a-b) )

2x+11=0   or   2x-11=0

x=\frac{-11}{2}    or   2x=11

x=\frac{-11}{2}    or   x=\frac{11}{2}

x=\pm \frac{11}{2}

Therefore option d) is correct

That is x equals plus or minus start fraction 11 over two end fraction

Complete the following proof.<br> Given: m ∠XOY = m ∠WOV<br> m YZ = m ZW<br> Prove: m XZ = m ZV
horsena [70]

Answer:

Step-by-step explanation:

m ∠XOY = m ∠WOV

so, m XY = m WV --- (i)

     { If angle subtended by two arcs at the center are equal, then length of arc are equal}

m YZ = m ZW  ------- (ii)    {given}

Add (i) and (ii)

XY + YZ = WV + ZW

XZ = ZV    

Hence proved.
