Sine and Cosine of any angle will always give a number less than 1. Why? (HINT Think about fractions and how Sine is oppositehypotenuse and Cosine is adjacenthypotenus )

Answers

Answer 1

Answer:

Hope this helped!

Step-by-step explanation:

The most easiest way to understand this is by considering a simple right angled triangle:-

For any right angled triangle

sin(theta)=perpendicular/hypotenuse

cos(theta)=base/hypotenuse

Since hypotenuse is the largest side so neither sin nor cos could be larger than 1.

A paddle boat company charges $15 rental fee plus $12.75 per hour for rentals. If Jimmy has $45, which inequality can he use to determine if he has enough money to rent a paddle boat for 4 hours?

a. 15 + 12.75x ≤ 45
b. 15 + 12.75x ≥ 45
c. 15x + 12.75 ≤ 45
d. 15x + 12.75 ≥ 45

Answers

Answer:

Step-by-step explanation:

$15 rental fee added to the 12.75 per hour. you have to multiply the 12.75 times the amount of hours rented, which we don't know yet so that's variable x. then he has only $45 to spend so it has to be equal to or less than that.

A rectangle a photo with dimension 3 inches wide by 4 inches long is enlarged to a length of 12 inches what is the width of the enlarged print

Answers

Answer:

9 inches wide

Step-by-step explanation:

so in the text it tells you that the rectangle is 3 inches wide by 4 inches long

then it gives you the final length but you need the width. so what i did is find out how much the increase of the length was, the length was4 at the start then ended at 12 to find out how much it increased i divided 12 by 4 and got 3. that shows that the object is 3 times larger so then I multiplied the original width by 3 which would be 3*3 which equals 9. so 9 is the width of the enlarged shape.

A cart weighing 60 lb is placed on a ramp inclined at 15° to the horizontal. The cart is held in place by a rope inclined at 60° to the horizontal, as shown in the figure. Find the force that the rope must exert on the cart to keep it from rolling down the ramp. (Round your answer to one decimal place in lbs.)

Answers

I assume you ignore friction. The cart is held in equilibrium, so the net force on the cart is zero.

There are 3 forces acting on the cart:

• weight (magnitude w, pointing down)

• normal force (mag. n, pointing perpendicular to the ramp)

• tension in the rope (mag. t, pointing 60º from the horizontal, or equivalently 60º - 15º = 45º from the parallel direction)

Split up the forces into horizontal and vertical components. We have

• horizontal:

t cos(60º) + n cos(105º) = 0

• vertical:

n sin(105º) + (-w) = 0

(the normal force has a direction of 105º from the horizontal because it's perpendicular to the ramp, so it forms an angle of 90º with the ramp, plus the 15º inclination of the ramp itself)

We're given that w = 60 lb, so

n sin(105º) = 60 lb

n ≈ 62.1 lb

Solve for t :

t cos(60º) = -n cos(105º)

t = -n cos(105º)/cos(60º)

t ≈ 32.2 lb

A large container for water weighs 21 pounds. If a gallon of water weighs 8.34 pounds, what is an equation that relates the weight of the water and the container, W, in pounds and the amount of water, A, in gallons?

Answers

Answer: W= 8.34A

Step-by-step explanation:

Given: Weight of a gallon of water = 8.34 pounds

Then, weight of the water in container = (Weight of a gallon of water ) x (amount of water)

If A = amount of water (in gallons)

W = weight of the water in container ( in pounds)

i.e. [tex]W= 8.34A[/tex]

Hence, the required equation : W= 8.34A

Step-by-step explanation:

Given that:

1575 shared in the ratio 1 : 2 : 1/2

Total sum of ratio = (1 + 2 + 1/2) = 3 1/2

Ratio 1 amount :

(1 / 3.5) * 1575 = 450

Ratio 2 amount :

(2 / 3.5) * 1575 = 900

Ratio 1/2 amount :

(1/2 ÷ 3.5) * 1575 = 225

Smallest share = $225

True. The principal is the amount loaned. If you are the person loaning the money to the bank (which is effectively how they make money), then they pay you back in the form of interest. The bank takes a share of that interest of course. They may have other fees as well.False. The compound interest depends on how frequently the money is compounded. Usually it's done monthly. Though your bank would likely say it somewhere in the fine print. It is only when annual compounding takes place is when statement #2 is true.True. If the item you're trying to buy is larger than what is in your account, then you'll be overdrawing your account. Your bank will likely charge an overdraft fee. So it's best to pay attention to your balance as much as possible. True. You can bank from your phone, computer, tablet or laptop and do so anywhere in the world. Of course you'll need access to the internet. Keep in mind that some banking services require in-person visits so not everything is done online. True. Not much to say here, other than this number is used for ATM withdrawals and point of sale purchases with a credit card (though it will depend on the card).False. An ATM is a machine that dispenses cash, and it accepts deposits as well (either cash or check; though it may depend on the specific machine). ATM stands for Automated Teller Machine. It basically is a robotic banker, hence the phrasing "automated teller". Coupled with online banking, ATMs help spread a bank's footprint and allow customers to truly bank from anywhere. False. Withdraw means to subtract from the balance. True. A deposit increases your balance because you are giving that money to the bank.False. A bank statement is a document that tells you how much you have in your account(s) at any given month. It also provides the amount of interest earned as well as various deposits and withdrawals made for that month.

The science center has 300 people in attendance on Tuesday. This is 150 percent of the attendance on Monday. Natasha is trying to figure out how many people were in attendance on Monday. Her work is shown below.

StartFraction part Over whole EndFraction = StartFraction 150 Over 100 EndFraction

StartFraction 150 times 2 Over 100 times 3 EndFraction = StartFraction 300 Over question mark EndFraction

Since 150 times 2 = 300, then 100 times 3 or 300 people were in attendance on Monday.

What mistake did Natasha make?
Natasha should have multiplied 100 by 2.
Natasha should have divided 150 by 3.
Natasha should have added 150 and 300.
