Answer:

33.6 cm

Step-by-step explanation:

We can use the formula for arc length to solve this.

s=r\theta

Where

s is the arc length

r is the radius

\theta is the angle subtended by the arc (in radians)

<u />

<u>The problem gives us theta = 2.8 radians and radius of the circle as 12 cm. We plug these into the formula and figure out the arc length (to 1 decimal place):</u>

s=r\theta\\s=(12)(2.8)\\s=33.6

2nd answer choice is right.

An artist designed a badge for a school club. Figure ABCD on the coordinate grid below shows the shape of the badge.
dedylja [7]

Answer:

(8, 4)

Step-by-step explanation:

<em>AD is enlarged to JM</em>

<em>AD² = 2² + 1² = 4 + 1 =5</em>

<em>AD =  √5</em>

then you plug in JM

<em>JM² = 6² + 3² = 36 + 9 = 45</em>

<em>JM = √45 = 3 √5</em>

<em>so if </em>

<em>JM=3 AD</em>

then

<em>ML= 3 DC </em>

<em>then you add</em>

<em>5+3=8</em>

the coordinates for point L are (8, 4)

równanie zmiany prędkość autokaru poruszającego się po prostym odcinku szosy i rozpoczynającego hamowanie od szybkości 20m/s ma
Rasek [7]

Answer:

s = 22.5 m

Step-by-step explanation:

the equation for the speed change of a coach moving along a straight section of the road and starting braking at a speed of 20 m / s has the form v (t) = 25-5t. Using integral calculus, determine the coach's braking distance.

v (t) = 25 - 5 t

at t = 0 , v = 20 m/s

Let the distance is s.

s =\int v(t) dt\\\\s =\int (25 - 5t)dt\\\\s= 25 t - 2.5 t^2 \\

Let at t = t, the v = 20

So,

20 = 25 - 5 t

t = 1 s

So, s = 25 x 1 - 2.5 x 1 = 22.5 m
