The first answer and the last one

Plug in each number into their designated spots.
Example with (0,5)

0 goes into x and 5 goes into the y variable and this is the equation now:

2*0 +4*5=20

0 times 2 = 0 and 4*5=20
So that is one of the correct answers.

Repeat the process and you find that the last option is also correct.

Answer:

$x^\frac{2}{3}$

Step-by-step explanation:

Using the power of power rule (multiply the exponents)

$x^\frac{4}{3}$ × $^\frac{1}{3}$ $x^\frac{2}{3}$ × $^\frac{1}{3}$

$x^\frac{4}{9}$ $x^\frac{2}{9}$

When exponents are multiplied, add the answers:

x ^ ( 4/9 + 2/9 )

x ^ ( 6/9 )

x ^ ( 2/3 )

garri49 [273]

Answer:

13 seconds.

Step-by-step explanation:

Given

$h = -4.9(t - 13)(t + 2).$

Required

Determine a reasonable solution for t

To do this, we equate h to 0.

$h = -4.9(t - 13)(t + 2).$ becomes

$0 = -4.9(t - 13)(t + 2).$

Divide through by -4.9

$0 = (t - 13)(t + 2).$

Reorder the expression

$(t - 13)(t + 2) = 0.$

Split

$t-13 = 0$ or $t + 2 = 0$

This gives:

$t = 13$ or $t = -2$

But time can't be negative, So:

$t = 13$
