Find the approximate side length of a square game board with an area of 164 in2

notsponge [240]

Squares have the same length and width.
Area of a rectangle/square is length X width
A=LW
164 = LW
Now we know L and W are the same because its a square.
13X13 is 169
12X12 is 144
It appears the lengths are just less than 13.

A model rocket is launched directly upward at a speed of 28 meters per second from a height of 12 meters. The function f(t) = -

Jet001 [13]

Answer:

6.11 seconds

Step-by-step explanation:

Given

$f(t) = -4.9t^2 + 28t + 12$

Required

When will it hit the ground?

When it hits the ground, f(t) = 0.

So, we have:

$0 = -4.9t^2 + 28t + 12$

Solve quadratic equation using formula

$t = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}$

$t = \frac{-28 \± \sqrt{28^2 - 4*-4.9*12}}{2*-4.9}$

$t = \frac{-28 \± \sqrt{1019.2}}{-9.8}$

$t = \frac{-28 \± 31.92}{-9.8}$

Split

$t = \frac{-28 + 31.92}{-9.8}$ or $t = \frac{-28 - 31.92}{-9.8}$

$t = \frac{3.92}{-9.8}$ or $t = \frac{-59.92}{-9.8}$

$t = -0.4$ or $t = 6.11$

Time can not be negative. So:

$t = 6.11$
