Answer:

2t + 16

Step-by-step explanation:

1. 0 seconds and 16 feet.

$2(0) + 16$
$0 + 16$

$16$

2. 1 second and 18 feet.

$2(1) + 16$
$2 + 16$
$18$

3. 2 seconds and 20 feet.

$2(2) + 16$
$4 + 16$
$20$

4. 3 seconds and 22 feet.

$2(3) + 16$
$6 + 16$
$22$

5. 6 seconds and 28 feet.

$2(6) + 16$
$12 + 16$
$28$

Therefore, the answer is 2t + 16.

What is the number if 50% of 25% of a number is 48?

dedylja [7]

Answer:

384

Step-by-step explanation:

If 48 is 50% of something, that means

48 + 48 = 96. Now, what number is 96 25% of? well 96 • 4 = 384. Now let's do the math backwards!

25 % of 384 is 96. 50 % of 96 is 48! so your answer is 384! Hope this helps!!!

<h3>What is Discriminant Formula?</h3>

The discriminant formula is used to determine the nature of the roots of a quadratic equation. The discriminant of a quadratic equation $ax^{2} +bx+c=0$ is D = $b^{2} -4ac$

If D > 0, then the equation has two real distinct roots.

If D = 0, then the equation has only one real root.

Given that: $Area\; of \;walkway,\; a(w)\;= 4w^{2} + 100 w$

also, area of walkaway = 464 square feet.

So, $4w^{2} + 100 w =464$

$4w^{2} + 100 w -464=0$

Using Discriminant method,

a=4, b=100, c=-464

$w= \frac{-b\pm\sqrt{b^{2}-4ac} }{2a}$

w= $\frac{-100\pm\sqrt{(100)^{2}-4*4*(-464)} }{2*4}$

w= $\frac{-100\pm\sqrt{17424} }{8}$

So, $w_1= \frac{-100+\sqrt{17424} }{8} \;\;\;\; w_2= \frac{-100-\sqrt{17424} }{8}$

$w_1= \frac{-100+132 }{8} \;\;\;\; w_2= \frac{-100-132}{8}$

$w_1 = 4 \;\;\;\; and \;\;\; w_2= -29$

Hence the width of the walkaway be 4 feet.
