What is the slope of the equation y = 5x - 7?<br> o<br> -7<br> o<br> 7.
Cerrena [4.2K]

Answer:

slope = 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 5x - 7 ← is in slope- intercept form

with slope m = 5

Which equation is represented by the intersection of the graphs below?<br><br> Image is above.
zaharov [31]

Option B:

sin x = 1 is the equation represented by the intersection of the graph.

Solution:

The graph lies between -1 and 1 in y-axis.

x-axis of the graph is all real numbers.

The graph oscillates between -1 and 1 and a shape that repeats itself every 2π units.

That is the domain of the graph is all real numbers.

The range of the graph is [-1, 1].

It clearly shows that, it is the graph of sinx = 1.

Hence sin x = 1 is the equation represented by the intersection of the graph.

Option B is the correct answer.

A horizontal curve is being designed around a pond with a tangent length of 1200 ft and a central angle of 29.86 degrees. If the
lara31 [8.8K]

Answer:

The correct answer is "1287.02 ft"

Step-by-step explanation:

Given that:

T = 1200 ft

PI = 145+00

\Theta = 29.86°

or,

  = 0.5211 rad

As we know,

The radius of curve is:

⇒ T = R \ tan\frac{\Theta}{2}

1200=R \ tan(\frac{0.5211}{2} )

1200=R \ tan(0.267)

    R = 4494.38 \ ft

The length of curve will be:

⇒ L=R \Theta

       =449.38\times 0.5211

       =2342.01 \ ft

hence,

Station PT will be:

= PI-T+L

= 145-1200+2341.01

= 1287.02 \ ft
