Answer:

13.46 s

Step-by-step explanation:

The time it takes James Bond to complete one full oscillation is the period of a pendulum of length, l which is, T = 2π√(l/g) where l = length of pendulum = length of rope = 45 m and g = acceleration due to gravity = 9.8m/s²

So, substituting the values of the variables into the equation, we have

T = 2π√(l/g)

= 2π√(45 m/9.8m/s²)

= 2π√(4.592s²)

= 2π × 2.143

= 13.46 s

So, it takes 13.46 s for him to complete one full oscillation.

Answer:

14.65

9.2

Step-by-step explanation:

For this question I will be using SOH CAH TOA and I will assume that you know that that means

For the first use I have the adjacent side and need to solve for the hypotonouse which means I will be using CAH

which means that cos35=12/x

solve for x and get 14.65

For the second one I have the opposite side and need the adjacent so I will use TOA

Tan41=8/x

I will do the same thing for the last one and get x=9.2

Answer:

Slope = 5

Point = (4, 2)

Step-by-step explanation:

Slope: 5

Step-by-step explanation:

This is called point slope form. y-y1=m(x-x1)

If m is slope then your slope is 5

Answer:

22.5miles

Step-by-step explanation:

For Map 1;

1 inches = 30miles

For Map 2:

2 inches = 15miles

1 inches = x

2x = 1 *15

x = 15/2

x = 7.5miles

This means that 1 inch represents 7.5miles on Map 2'

The distance between the two cities in miles = 30miles - 7.5miles

The distance between the two cities (in miles) = 22.5miles

Answer:

a) Factorizing [tex]6p^2 - 36p + 30[/tex] we get [tex]6(p-5)(p-1)[/tex]

b) Factorizing [tex]4y^2-64y+256[/tex] we get [tex]4(y-8)(y-8)[/tex]

Step-by-step explanation:

Factorise the given expressions :

a) [tex]6p^2 - 36p + 30[/tex]

First we take 6 common:

[tex]6p^2-36p+30\\=6(p^2-6p+5)\\=6(p^2-5p-p+5)\\=6(p(-5)-1(p-5))\\=6(p-5)(p-1)\\[/tex]

So, factorizing [tex]6p^2 - 36p + 30[/tex] we get [tex]6(p-5)(p-1)[/tex]

b) [tex]256 -64y + 4y^2[/tex]

Rearranging terms:

[tex]4y^2-64y+256[/tex]

Taking 4 common

[tex]4(y^2-16y+64)\\4(y^2-8y-8y+64)\\4(y(y-8)-8(y-8))\\4(y-8)(y-8)[/tex]

So, factorizing [tex]4y^2-64y+256[/tex] we get [tex]4(y-8)(y-8)[/tex]

Answer:

Answer: 3.63 miles

Step-by-step explanation: I think you meant to type 2.12 and 4.25 so I'm just going to go by that. To figure out how many more miles he needs to run, you add the amount he already ran together, and then subtract that from his goal. 4.25 plus 2.12 equals 6.37. 10 minus 6.37 equals 3.63. He needs to run 3.63 miles on Wednesday, in order to reach his goal of 10 miles.

Answer:

300 nickels

Step-by-step explanation:

Reading the question, someone has 435 nickels and dimes.

The total is $28.50.

You're trying to find how many nickels he has.

All you need to do is set up a system of equations.

I'm going to use x as the number of nickels and y as the number of dimes.

Based on the question, you can say that

x + y = 435

(the number of nickels and dimes have t equal 435)

and 0.05x + 0.1y = $28.50

(nickels are 5 cents and dimes are 10 cents)

You want to solve for x, the number of nickels.

You can manipulate the first equation by subtracting x on both sides.

After you do that, you will get y = 435 - x. Now, you can substitute this equation into the second one.

First, you can distribute the 0.1.

0.05x  + 0.1(435 - x) = 28.50

Then, you can put the two x's together.

0.05x + 43.5 -0.1x = 28.50

Next, you can subtract 43.5 on both sides to isolate x.

-0.05x + 43.5 = 28.50

Finally, you can divide on both sides to get x, which is the number of nickels.

-0.05x = - 15

x = 300 nickels
