Answer:

167.2 m/sec

Step-by-step explanation:

Convert 602 km/hr to m/sec, as follows:

602 km 1000 m

------------ * ----------------- = 602,000 m/hr

hr 1 km

Recall that 1 hr = 3600 sec. Convert 602,000 m/hr to m/sec:

602,000 m 1 hr

------------------ * ---------------- = 167.2 m/sec

1 hr 3600 sec

Find the length of side x in simplest radical form with a rational denominator

Angelina_Jolie [31]

Answer:

The length of x=3/1

Step-by-step explanation:

Given the right triangle

Ф = 30

We know that

sin Ф = opposite/hypotenuse

The opposite of angle 30° = x

The hypotenuse is = 6

sin 30 = opposite/hypotenuse

1/2 = x/6 ∵ sin 30 = 1/2

1/2 × 6 = x

6/2 = x

3/1 = x

Therefore, the length of x=3/1

Please help with this area

agasfer [191]

Answer:

L = 7 W= 12

Step-by-step explanation:

Ok so we already know that a rectangle is not even so the numbers will have to be 2 diff numbers.

The length is 5 feet less then width

w*l= 84

1* 84 2* 41 3*28 4*21 6*14 7*12

84-1 41-2 28-3 21-4 14-6 12-7

83 39 25 19 8 5

So,

your equation would be l*w = 7*12

Calculate, to four decimal places, the first ten terms of the sequence. an = 1 +(−4/9)^n

Lemur [1.5K]

The first ten terms of the sequence $a_n=1 + (-\frac{4}{9} )^n$ is 0.5556, 1.1975, 0.9122, 1.039, 0.9827, 1.0077, 0.9966, 1.0015, 0.9993 and 1.0003

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Given that:

$a_n=1 + (-\frac{4}{9} )^n\\\\When\ n=1:a_1=1 + (-\frac{4}{9} )^1=0.5556\\\\When\ n=2:a_2=1 + (-\frac{4}{9} )^2=1.1975\\\\When\ n=3:a_3=1 + (-\frac{4}{9} )^3=0.9122\\\\When\ n=4:a_4=1 + (-\frac{4}{9} )^4=1.039\\\\When\ n=5:a_5=1 + (-\frac{4}{9} )^5=0.9827\\\\When\ n=6:a_6=1 + (-\frac{4}{9} )^6=1.0077\\\\When\ n=7:a_7=1 + (-\frac{4}{9} )^7=0.9966\\\\When\ n=8:a_8=1 + (-\frac{4}{9} )^8=1.0015\\\\When\ n=9:a_9=1 + (-\frac{4}{9} )^9=0.9993\\\\$

$When\ n=10:a_{10}=1 + (-\frac{4}{9} )^{10}=1.0003\\$

The first ten terms of the sequence $a_n=1 + (-\frac{4}{9} )^n$ is 0.5556, 1.1975, 0.9122, 1.039, 0.9827, 1.0077, 0.9966, 1.0015, 0.9993 and 1.0003
