Answer: 16) y=-0.5x+3 and 17) y=2x-3

Step-by-step explanation:

16: The slope-intercept form of a line is y=mx+b, where m is the slope, and b is the y-value at the y-intercept.

Since y=3 at x=0, the y-intercept is (0,3), and b=3.

Slope= $\frac{y_{2} -y_{1} }{x_{2}-x_{1} }$ where ( $x_{1} ,y_{1}$ ) and ( $x_{2} ,y_{2}$ ) are two points on the line. Choose (0,3) and (2,2):

Slope= $\frac{2-3}{2-0}$ =-0.5

Plug m=-0.5 and b=3 into y=mx+b:

y=-0.5x+3

17: The slope-intercept form of a line is y=mx+b, where m is the slope, and b is the y-value at the y-intercept.

Because y=-3 at x=0, the y-intercept is (0,-3), and b=-3.

Slope= $\frac{y_{2} -y_{1} }{x_{2}-x_{1} }$ where ( $x_{1} ,y_{1}$ ) and ( $x_{2} ,y_{2}$ ) are two points on the line. Choose (0,-3) and (1,-1):

Slope= $\frac{-3-(-1)}{0-1}$ = $\frac{-2}{-1}$ =2

Plug m=2 and b=-3 into y=mx+b:

y=2x-3

F(x)=4^x and g(x)=4^x+2

dsp73

Given:

The two functions are:

$f(x)=4^x$

$g(x)=4^x+2$

To find:

The type of transformation from f(x) to g(x) in the problem above and including its distance moved.

Solution:

The transformation is defined as

$g(x)=f(x+a)+b$ .... (i)

Where, a is horizontal shift and b is vertical shift.

If a>0, then the graph shifts a units left.
If a<0, then the graph shifts a units right.
If b>0, then the graph shifts b units up.
If b<0, then the graph shifts b units down.

We have,

$f(x)=4^x$

$g(x)=4^x+2$

The function g(x) can be written as

$g(x)=f(x)+2$ ...(ii)

On comparing (i) and (ii), we get

$a=0,b=2$

Therefore, the type of transformation is translation and the graph of f(x) shifts 2 units up to get the graph of g(x).

You want to put a 5 inch thick layer of topsoil for a new 16 ft by 34 ft garden. The dirt store sells by the cubic yards. How ma

shepuryov [24]

Answer: About 8.5 cubic yards

Step-by-step explanation:

Given : The length of the garden = 16 ft.

The width of the garden = 34 ft.

The depth of the thick layer of topsoil on the garden = 5 inch

= $\dfrac{5}{12}\text{ ft.}$ [Since 1 foot = 12 inches]

The volume of a rectangular prism :-

$V=l*w*h$ , where l is length , w is width and h is height.

The number of cubic feet of topsoil required will be

$V=16\times34\times\dfrac{5}{12}=\dfrac{680}{3}\text{cubic feet}$

Since 1 yard = 3 feet

$1\text{ foot}=\dfrac{1}{3}\text{ yard}$

$V=\dfrac{680}{3}\times\dfrac{1}{3}\times\dfrac{1}{3}\times\dfrac{1}{3}=8.3950617284\approx8.50\text{cubic yards}$
