Select the factors that can be divided out to simplify the multiplication problem: 4/26 x 13/20. Select all that apply. A. 2 B.

Tcecarenko [31]

$\dfrac{4}{26} \times \dfrac{13}{20}$

-------------------------------------
Divide by factor of 4.
-------------------------------------
<em>*Or divide by the factor of 2 twice</em>

$\dfrac{1 \times 4}{26} \times \dfrac{13}{5 \times 4}$

$\dfrac{1}{26} \times \dfrac{13}{5}$

-------------------------------------
Divide by factor of 13.
-------------------------------------

$\dfrac{1}{2 \times 13} \times \ \dfrac{1 \times 13}{5}$

$\dfrac{1}{2} \times \dfrac{1 }{5}$

-------------------------------------
Combine into single fraction.
-------------------------------------
$\dfrac{1}{10}$

--------------------------------------------------------------------------
Answer: The factors are 2, 4 and 13

An object has been thrown straight up into the air. The formula h = vt - 16t^2 gives the height of the object above the ground a

Oxana [17]

Answer:

8 seconds.

Step-by-step explanation:

To solve this question, we need to find the time, $t$ , when $h = 0$ , that is, when the height of the object above the ground is 0 feet.

Substituting $v = 128$ feet per second and $h = 0$ gives the quadratic:

$0 = 128t - 16t^{2}$

Since 128 is divisible by 16, it can be reduced to $0 = 16(8t - t^{2})$ .

We must now solve for $t$ .

We can easily see that one answer to the equation is 0,

$8(0) - (0)^{2} = 0$ (we need not concern ourselves with the 16 outside of the parenthesis as in the equation above, since 16 multiplied by 0 is 0). However this is the time the object is released into the air.

The second answer, $t = 8$ is also easy to see by inspection:

$8(8) - (8)^{2} = 0$ .

Therefore the object lands 8 seconds after it is thrown.
