4.5
Explanation
Based on the given conditions, formulate:
27 ÷ 6
Reduce the fraction:
9/2
get the result:
4.5 or 4(1/2)
Answer:
the time is 1.57 sec and the distance is 49.32mm
Step-by-step explanation:
Given that,
The angle is 180°
Angular velocity is 2rev/sec
The radius is 10mm
we are to find the time and distance traveled at that time
The formula is
θ = at
where t is the time,
a is the angular velocity
θ is angle in radian
so,
θ = 180° × π/180°
θ = π
= 3.14
Hence ,
θ = at
3.14 = 2t
t = 1.57sec
let the distance be xmm
Therefore , the time is 1.57 sec and the distance is 49.32mm
We have to find the focus of the parabola with equation:
In order to find the focus, we first need to convert the equation of parabola to its standard form, as shown below:
Comparing this equation to the similar general equation of parabola, we get:
k = -3
p= 3/4
h = - 2
The focus of the general parabola is located at ( h+p, k)
Using the values, we get:
Focus of the given parabolic satellite =
Answer:
(p+2)(p+4)
Step-by-step explanation:
Factor p2+6p+8
p2+6p+8
=(p+2)(p+4)
Answer:
When subtracting expressions, we are applying the distributive property, where a multiple of an expression in brackets is applied to to each term.
e.g.
a(x + y) = ax + ay
In the case of subtracting an expression, we're doing the same thing, but in the example above, "a" would be equal to -1.
(a + b) - (c + d) ≡ (a + b) + -1(c + d)
And so the negative one is distributed across the terms within the brackets.
