Which equation is in slope-intercept form and represents a line with slope 0 through the point (2, 3)?

1 answer:

4 0

Y = mx + b
slope(m) = 0
(2,3)...x = 2 and y = 3
now u sub
3 = 0(2) + b
3 = b

equation is : y = 0x + 3...or just simply, y = 3

The sum of the angle measures of the polygon is 540°. Write and solve an equation to find the value of x.

nikklg [1K]

Answer:

x = 23°

Step-by-step explanation:

Looking at the diagram above, we can see that it is Pentagon.

The sum of interior angles in a Pentagon (5 sides polygon) = 540°

This is because in a Pentagon, from the vertex we can draw 2 diagonals that would result in 3 triangles.

Sum of angles in a triangle = 180°

Hence, the sum of angles in a Pentagon = 3 × 180°

= 540°

Hence,

540° = 85° + 5x° + 5x° + 5x + 5° + 5x - 10°

540° = 85° + 5° - 10°+ 5x° + 5x° + 5x° + 5x°

540° = 80° + 20x°

540° - 80° = 20x°

460° = 20x°

x° = 460/20

x = 23°

Therefore, the value of x = 23°

Er uvay, vvildt is your average velocity!

The acceleration of the fire truck is 1.666 m/s².

<u>Step-by-step explanation:</u>

Acceleration is the measure of change in velocity with respect to time. So as the initial velocity of the fire truck is given as 0 km/hr and the final velocity is given as 66 km/hr. So at first the truck is at rest and on switching on the engine, the truck gets to the velocity of 66 km/hr in 11 seconds.

$\text { Acceleration }=\frac{\text {Change in velocity}}{\text {time}}$

But first the units of velocity should be changed from km/hr to m/s

1 hour = 3600 seconds

1 km = 1000 m

So, $66\ {k m}{h r}=\frac{66 \times 1000}{3600} m / s$

Converted Velocity = 18.33 m/s

Then, the acceleration will be

$\text { Acceleration }=\frac{18.33-0}{11}$

Acceleration = 1.666 m/s²

So, the acceleration of the fire truck is 1.666 m/s².
