Answer:
<em>We</em><em> </em><em>can</em><em> </em><em>say</em><em> </em><em>that</em>
<em> </em>3x + x + 8 = 32
<em>So</em><em>:</em><em> </em>
3x + x + 8 = 32
4x = 32 - 8
4x = 24
x = 24/4
<em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>6</u></em>
Step-by-step explanation:
Given expression is x⁴-kx²+4 =0
x−2 is a factor of the given expression.
So, x=2
Substitute in the equation, we get
2⁴-k(2)²+4
⇒16+4k+4=0
⇒4k=−20
⇒k=−5
Answer:

Step-by-step explanation:
The Cylindrical coordinates are:
x = rcosθ, y = rsinθ and z = z
From the question, on the xy-plane;


where:
0 ≤ r ≤
and 0 ≤ θ ≤ 2π
∴












Answer:
Average number of people ride ferry boat = 62 or 63 people
Step-by-step explanation:
Given:
Number of people ride ferry boat
58 59 60 61 62 63 64 65 66 67
Find:
Average number of people ride ferry boat
Computation:
Average mean = Sum of all observation / Number of observation
Average number of people ride ferry boat = [58 + 59 + 60 + 61 + 62 + 63 + 64 + 65 + 66 + 67] / 10
Average number of people ride ferry boat = [625] / 10
Average number of people ride ferry boat = 62.5
Average number of people ride ferry boat = 62 or 63 people
Answer: 2929 π inch
Step-by-step explanation:
Circumference is given by= 2πr
Here r= 1010 inches
So Tip of minute hand moves= 2π (1010inch)
= 2020 π inch for an hour
Now it comes from 12 to 33 o'clock= 1.45 hour so,
Tip of minute hand moves= 2020 π inch x 1.45
Tip of minute hand moves= 2929 π inch
