The time taken that should be rapidly are distinct 3 seconds later should be considered as 24.78 m/s.
Calculation of the time taken:Here the point should be considered directly under the center of the bridge as the origin
Here
x = 20t, y = 15t, z = 10
let us assume s be the distance between them at time t,
So it be like
[tex]s^2 = (20t)^2 + (15t)^2 + 10^2 = 625t^2 + 100[/tex]
2s ds/dt = 1250t
ds/dt = 625t/s
Now at the time when
t = 3,
[tex]s = \sqrt (625*9+100)[/tex] = 75.6637
So,
ds/dt = [tex]625*3/75.6637[/tex] = 24.78 m/s

Solve for the last missing side any way you'd like.
55°
10
35°
8.2
Answer:
12.2
Step-by-step explanation:
Let C be the last angle c + 55° + 35° = 180° (sum of angles in a triangle)
C + 90° = 180°
C = 180° - 90°
C = 90°
Let c be the last side
Using the sine rule a/sinA = b/sinB = c/sinC
Using any of the other two sides,
10/sin55° = c/sin90°
c = 10/sin55° × sin90°
c = 10/0.8192 × 1
c = 12.21
c ≅ 12.2

Solve for t in terms of the other variables.
k= 3tm + rs
Answer:
[tex]t=\dfrac{k-rs}{3m}[/tex]
Step-by-step explanation:
It's like solving any equation, except we have letters instead of numbers .
k = 3tm + rs {subtract rs from both sides}
k - rs = 3tm {divide both sides by (3m)}
[tex]\dfrac{k-rs}{3m}=t[/tex] {swap sides}
[tex]t=\dfrac{k-rs}{3m}[/tex] m≠0
{m must be ≠0 because you cannot divide by 0. There is no t for m=0}
How do you do this ?
Answer:
fourth option
Step-by-step explanation:
A translation of 6 units right ( positive x- direction ) means add 6 to the original x- coordinate.
A translation of 2 units down ( negative y- direction ) means subtract 2 from the original y- coordinate.
Thus the translation rule is
(x, y ) → (x + 6, y - 2 )

6. What is the vertex of the graph of y = x2 – 8x + 6
(Hint: use x = - to find the AOS)
b
2a
Show work
Answer:
[tex] \boxed {( 4, - 10)}[/tex]
Step-by-step explanation:
[tex]y = {x}^{2} - 8x + 6[/tex]
Here are some formulas that you might need.
[tex]h = - \frac{b}{2a} \\ k = \frac{4ac - {b}^{2} }{4a} [/tex]
The vertex of graph is at (h, k) from the vertex form.
[tex]x = h \\ y = k[/tex]
Substitute in the formula.
[tex]h = - \frac{( - 8)}{2(1)} \\ h = \frac{8}{2} \\ h = 4[/tex]
Next we find the value of k.
[tex]k = \frac{4(1)(6) - {( - 8)}^{2} }{4(1)} \\ k = \frac{24 - 64}{4} \\ k = \frac{ - 40}{4} \\ k = - 10[/tex]
Therefore the vertex is (4,-10).

7(x + 5) = -35
O
x = -10
x = 5
O x = -5
X = 0
Answer: x = -10
Step-by-step explanation:
7 (x + 5) = -35
Distribute 7 to x + 5
7 * x = 7x
7 × 5= 35
7x + 35 = -35
Subtract both sides by 35
7x = - 70
Divide both sides by 7
x = -10

List all the common multiples of 9,12 and 15 between 1 and 100
Answer:
There is no common multiple of 9, 12 and 15 between 1 and 100
Step-by-step explanation:
The common multiples of 9, 12 and 15 between 1 and 100
Fist the lowest common multiple
9 = 3 * 3
12 = 3 * 4
15 = 3 * 5
Hence the lowest common multiple
= 3 * 3 * 4 * 5
= 180
Since the lowest common multiple of 9, 12 and 15 is greater than 100, it means that there is no common multiple of these numbers between 1 and 100
Write a fraction that is equivalent to 7 divided by 13
Answer:
14/26
Step-by-step explanation:
a fraction that is equivalent to 7/13 is 14/26 because to make the fraction equivalent the numerator and denominator have to be multiplied by the same number so another fraction that would be equivalent would be 21/39

An electrician has 3 7/10 cm of wire. He needs only 2 5/8 cm
of wire for a job. How much wire does he need to cut?
Answer:
The answer can either be 2 5/8 cm in terms of grammar but because it is a mathematics question you will have to subtract the fractions giving us 1 3/40 cm
Step-by-step explanation:
3 7/10 - 2 5/8
subtract the whole numbers and find the LCM of the fractions which is 40
=1 (( 28-25)/40)
=1 3/40cm
