51/4 ÷ 22/7
the divisor is replaced with a multiplier
51/4 * 22/7
51*7 / 4*22
= 357/44

A watermelon is launched from a 25-foot tall platform at a carnival. The watermelon's height h (in feet) at time t seconds can b

Nataly [62]

Answer:

The maximum height of the watermelon is 74 feet.

Step-by-step explanation:

The watermelon reaches its maximum height when its velocity is zero. Mathematically speaking, velocity is the first derivative of the function height, that is:

$v(t) = \frac{d}{dt} h(t)$ (1)

Where $v(t)$ is the velocity, in feet per second.

If we know that $h(t) = -16\cdot t^{2}+56\cdot t +25$ and $v(t) = 0\,\frac{ft}{s}$ , then the time associated with maximum height is:

$v(t) = -32\cdot t +56$ (2)

$-32\cdot t + 56 = 0$

$t = 1.75\,s$

Now we evaluate the function height at time found in the previous step: ( $t = 1.75\,s$ )

$h(t) = -16\cdot t^{2}+56\cdot t +25$

$h(1.75) = 74\,ft$

The maximum height of the watermelon is 74 feet.

2. You are trying to determine which box of Honey Nut Cheerios to buy, The Family Size box weighs

Katyanochek1 [597]

Answer:

Mega Size

Step-by-step explanation:

Given

Family Size

$Weight = 19.5\ oz$

$Cost = \$3.64$

Mega Size

$Weight = 29.4\ oz$

$Cost = \$4.98$

Required

Determine which has a better value

First, we calculate the unit rate of both.

$Unit\ Rate = \frac{Cost}{Weight}$

For the family size:

$Unit\ Rate = \frac{\$3.64}{19.5\ 0z}$

$Unit\ Rate = \$0.187\ per\ 0z$

For the mega size:

$Unit\ Rate = \frac{\$4.98}{29.4\ 0z}$

$Unit\ Rate = \$0.169\ per\ 0z}$

By comparing the unit rates, the mega size has a better value because it costs cheaper per unit rate

Which graph is a translation of f(x) = x2 , according the rule:

bixtya [17]

For this case we have the following original function:
$f (x) = x ^ 2
$
We apply the following transformation:
Vertical displacements:
Assume k> 0
To graph f (x) - k, move the graph k units down.
Applying the transformation for k = 5 we have:
$y = x ^ 2 - 5
$
Therefore, the graph moves 5 units down.
Answer:
Third graph
