The function g(t) = - 16t2 + vt + h represents the height of an object, g, in feet, above the ground in relation to the time, t,

timurjin [86]

Answer:

$g(t) = -16t^2+80t$ .

Step-by-step explanation:

We are given that $v=80$ and $h=0$ (because that's the ground), so substituting that into $g(t) = -16t^2+vt+h$ gives $g(t) = -16t^2+80t$ .

Answer:

Scientific Notation: 4.88 ×10^7

Standard Form: 4.88 ×10^7

Step-by-step explanation:

6.1×10^(-3) = 0.0061

8×10^9 = 8000000000

0.0061×8000000000 = 48800000

$= 4.88 \times {10}^{7}$

Anastasy [175]

Answer:

When (-1,-4) is substituted into the second equation, the equation is true.

The ordered pair (-1,-4) is a solution to the system of linear equations.

When (-1,-4) is substituted into the first equation, the equation is true.

Step-by-step explanation:

Given

$x - y = 3$

$7x - y = -3$

Required

What is true about $(x,y) = (-1,-4)$

To do this, we substitute -1 for x and -4 for y in both equations;

For $x - y = 3$

$-1 - (-4) = 3$

$-1 + 4 = 3$

$3 = 3$

Hence: $(-1,-4)$ is true for $x - y = 3$

For $7x - y = -3$

$7(-1) - (-4) = -3$

$-7 +4 = -3$

$-3 = -3$

Hence: $(-1,-4)$ is true for $7x - y = -3$
