The minute hand of a clock is 3 inches long. How far does the tip of the minute hand move in 40 minutes?

Mkey [24]

Answer:

4π in ≈ 12.57 in

Step-by-step explanation:

One full revolution (2π radians) is made in 60 minutes. In 40 minutes, the hand moves through an angle θ of (40/60)(2π) = 4π/3 radians. The length of the arc is ...

s = rθ = (3 in)(4π/3) = 4π in ≈ 12.57 in

First four terms of f(n)=3n-1

gavmur [86]

First four terms would be n = 1, 2, 3, 4

f(1) = 3 ( 1 )( 1 + 3 )
= 3 * 4
=12
f(2) = 3 ( 2 )( 2 + 3 )
= 6 * 5
= 30
f(3) = 3 ( 3 )( 3 + 3 )
= 9 * 6
= 54
f(4) = 3 ( 4 )( 4 + 3 )
= 12 * 7
= 84 hope this helps!

A) For ΔJKL use the Triangle Proportionality Theorem to solve for x.

scoray [572]

Answer:

Part a) The value of x is 10

Part b) The perimeter of triangle JKL is $79\ units$

Step-by-step explanation:

Part a) Find the value of x

we know that

The <u>Triangle Proportionality Theorem,</u> states that if a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally

$\frac{3x-5}{3x-5+10}=\frac{28-8}{28}\\ \\\frac{3x-5}{3x+5}=\frac{20}{28} \\ \\(3x-5)(28)=(3x+5)(20) \\ \\84x-140=60x+100\\ \\84x-60x=140+100\\ \\24x=240\\ \\x=10$

Part b) we know that

The perimeter of triangle JKL is equal to

$P=JK+KL+JL$

substitute the values

$P=(3x+5)+28+16=3x+49$

substitute the value of x

$P=3(10)+49=79\ units$
