Answer:

Graph B

The graph in the attached figure

Step-by-step explanation:

we have

$f(x)=2(3)^{x}$

This is a exponential function

of the form

$f(x)=a(b)^{x}$

where

a is the initial value

b is the base

r is the rate

b=1+r

In this problem

a=2 ----> the y-intercept

b=3

1+r=3 -----> r=3-1=2 -----> r=200%

The y-intercept of the graph is equal to 2

As x increases the value of f(x) increases

therefore

Graph B

Rearrange each of the following in slope/y-intercept form, y = mx + b.

attashe74 [19]

Answer:

${ \tt{3x - 6y + 8 = 0}} \\ { \tt{ 6y = 3x - 8}} \\ { \boxed{ \bf{y = \frac{1}{2} x - \frac{4}{3} }}}$

${ \tt{ - 2x - 5y - 2 = 0}} \\ { \tt{5y = - 2x + 2}} \\ { \boxed{ \bf{y = - \frac{ 2}{5} x + \frac{2}{5} }}}$

I need help please and thank you

Answer:

3.33×10⁴

Step-by-step explanation:

You can use the hint, or you can use a common exponent. Here is the latter case.

(3.9×10⁴) -(5.7×10³) = (3.9×10⁴) -(0.57×10⁴) = (3.9 -0.57)×10⁴

= 3.33×10⁴

_____

With a little practice, you can see the effect on exponents of moving the decimal point. Here, we have ...

5.7×10³ = (0.57×10)×10³ = 0.57×(10×10³) = 0.57×10⁴

When adding or subtracting in scientific notation, all that is required is that the exponents of all the numbers be the same. The hint says make all the exponents be 0. Above, we have chosen to make them all be 4. You could also use 3:

(3.9×10⁴) -(5.7×10³) = (39×10³) -(5.7×10³) = (39 -5.7)×10³

= 33.3×10³ = 3.33×10⁴

A tennis ball machine serves a ball vertically into the air from a height of 2 feet, with an initial speed of 120 feet per secon

Makovka662 [10]

Answer:

The maximum height is reached after 3.75 seconds.

Step-by-step explanation:

Assuming the deceleration due to gravity is unaided by air resistance, gravity causes the ball to lose vertical speed at the rate of 32 ft/s every second. The initial vertical speed of 120 ft/s will decline to zero when t satisfies ...

... 120 ft/s - (32 ft/s²)t = 0

... (120 ft/s)/(32 ft/s²) = t = 3.75 s

The ball will not go any higher after its vertical speed is zero.
