If an object is projected vertically upward from ground level with an initial velocity of 320 ft/sec, then its distance s above

the ground after t seconds is given by s=-16t^2+320t. For what values of t will the object be more than 1536 feet above the ground?

Type the single exponent that would appear on the 7: *

liq [111]

You add the exponent. You never multiply it.

Hope this helps!

PLEASE HELP WILL MARK BRAINLIEST Write the equation of the line parallel to the given line and passing through the given point.

Naily [24]

The parallel lines have the same slope.

The slope-intercept form: y = mx + b

m - a slope.

We have 6x + y = 4 |subtract 6x from both sides

y = -6x + 4 → m = -6.

The slope-point form:

$y-y_1=m(x-x_1)$

We have m = -6 and (-2, 3).

Substitute:

$y-3=-6(x-(-2))\\\\y-3=-6(x+2)\\\\y-3=(-6)(x)+(-6)(2)\\\\y-3=-6x-12\qquad|+3\\\\y=-6x-9\qquad|+6x\\\\6x+y=-9$

<h3>Answer: 6x + y = -9.</h3>

How do i write the difference of a number x and 2 is 7 as an equation

HACTEHA [7]

You can quiet literally write the question as it is.

The difference of a number x and 2 is 7.

The difference of a number x and 2 can be written as x-2

is can be written as equal or =

This statement can be translated as x-2=7.

It is as simple as that!

Somebody tell me this ...
