How to write sin and cos and all?

Like should they be in first letter uppercase, or whole lowercase?

My maths teacher is writing with first letter uppercase, but I see many YouT.ubers and all writing it in fully lowercase! so someone clear it up and pick me out of this puzzled condition....

Answers

Answer 1
Any cosine function can be written as a sine function. y = A sin(Bx) and y = A cos(Bx). The number, A, in front of sine or cosine changes the height of the graph. The value A (in front of sin or cos) affects the amplitude (height).

Rewrite the equation below so that it does not have fractions

2/3x-5=3/4

Answers

Answer:

Step-by-step explanation:

The best way to do this problem is to find the lowest common denominator.

2/3 : 3*2/(3*3)

3/4 : 3*3 / 3*4

Notice what you have done. You have multiplied both denominators by something that gets rid of the denominators, or will when you multiply by 4 * 3 = 12

So multiply the equation by 12

(2/3 x- 5  = 3/4 ) 12

8x - 60 = 9                                 Add 60 to both sides

8x - 60 = 9                                 Combine

8x = 69                                       Divide by 8

x = 69/8

x = 8  5/8

write the equation
it passes through (-5,-7) and (-5,7)

Answers

Answer:

x = -5

Step-by-step explanation:

Find the gradient:

m = change in y ÷ change in xm = (7 - -7) ÷ (-5 - -5)m = 14 ÷ 0m = 0 - There is no gradient, and it is a vertical line

The equation is x = -5, because in both co-ordinate pairs, the x is -5 - only the y changes

Hope this helps!

Step-by-step explanation:

so the question supposed be " 15-20 divided by 2(4) + 20

15-20 which is also 15 + (-20)= -5

2(4)=8, 8+20=28

so it can simplify into -5 / 28

Paul is riding his bike 48 miles to the beach. His average rate of speed is 13.8 miles per hour. Paul stopped for a snack after 3 hours. How many miles does he have to go after his snack? Round your answer to the nearest tenth if necessary.
Paul has 3.5 miles to go after his snack.
Paul has 6.6 miles to go after his snack.
Paul has 34.2 miles to go after his snack.
Paul has 45.0 miles to go after his snack.

Answers

Answer:

Paul has 6.6 miles to go after his snack.

Step-by-step explanation:

Speed is the rate of moving. The speed can be calculated by dividing the distance traveled by the amount of time it took.

speed= distance/time  , v=d/t

So,from Paul's average speed we can calculate how much distance he has passed after 3 hours.

distance_3h=v*t=13.8 miles per hour * 3 hours

distance_3h=41.4 miles

There are total 48 miles to the beach, so Paul have to go 48miles-distance_3h after his snack, which gives:

48-41.4=6.6 miles

The graph represents the data cost for monthly Internet service for a cell phone.

On a coordinate plane, a graph titled Cell Phone Internet Service shows Gigabytes Used on the x-axis and Monthly Cost in dollars on the y-axis. A piecewise function has 3 lines. The 1st line has a closed circle at (0, 15), continues horizontally at y = 15, then has a closed circle at (2, 15). The 2nd line has an open circle at (2, 20) and then continues up to a closed circle at (6, 40). The 3rd line has an open circle at (6, 50) and then continues horizontally at y = 50.

The answer is B) 2/3x=5 and E) 6x-3+8=11.

Step-by-step explanation:

Basically, all we have to do is see which of the answer options contains an equal sign. So lets go from there:

Does A have an equal sign? We can see the plus sign, a coefficient, and a variable, but we don't have an equal sign, so A is not an equation.

What about B? Well, we can see an equal sign that is showing that two values of an expression equal each other, so yes, B is an equation.

What about C? Well, we can see the minus sign, a variable, and a coefficient, but there is no equal sign. Therefore C is not an equation.

What about D?  Well, D has parenthesis, variables, coefficients, and a plus sign, but no equal sign. So no, D is not an equation.

Finally, is E and equation? Well, we can see that there are two values that are equal to each other as is shown by an equals sign. So yes, E is an equation.

Answers

Answer:

Y=5x+b

B= y-5x

hope this helps

Answer:

b = y-5x

Step-by-step explanation:

y =5x+b  

Step 1- Cancelation minus or add the numeric first both side then variable numbers, then variables then exponents ^2 last.

In this case if we were asked to find x we would divide both sides by 5. But we are not asked that and instead asked to find b so we just apply and keep 5x together through add or subtraction.

For exponents we sqrt both sides. But this equation doesnt show any exponents so we stop at -5 each side.

y-5x=b

Step 2 - keep doing to isolate b we have no more to change other than reverse to show b first.

b = y-5x

The answer is y = 0.02 (0.05)^x

Exponential functions follow the form y = ab^x.

a is the y intercept when x is at 0. Because the last part, b^x will just be 1 since any number raised to 0 is 1.

b is the multiplier, and it’s raised to how many times it’s being multiplied.

So like you said, it’s being multiplied by 0.5. b = 0.05. And a=0.02.

Jorge has a standard deck of 52 cards and a six-sided number cube. What is the probability that he will draw a diamond from the deck of cards and roll a number greater than two? Write your answer as a simplified

Answers

The probability that Jorge draw a diamond from the deck of cards and roll a number greater than two is 2/39

Probability is the like likelihood or chance that an event will occur.

Probability = Expected outcome/Total  outcome

If Jorge has a standard deck of 52 cards, the total outcome is 6

If Jorge draw a diamond card, the probability that he will draw a diamond card is 4/52 = 1/13

For a six-sided cube, the total outcome is 6. If he rolls a number greater than two, the expected outcome will be 4

The probability that he rolls a number greater than 2 is 4/6 = 2/3

The probability that Jorge draw a diamond from the deck of cards and roll a number greater than two is 1/13 * 2/3 = 2/39

You ate 1/6 of a pizza and your brother eats 5/8 of the pizza .How much did your brother eat compared to you

Answers

Answer:

Subtract: 5/8 - 1/6 = 5 · 3/8 · 3 - 1 · 4/6 · 4 = 15/24 - 4/24 = 15 - 4/24 = 11/24

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(8, 6) = 24. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 6 = 48. In the following intermediate step, the fraction result cannot be further simplified by canceling.

In other words - five eighths minus one sixth = eleven twenty-fourths.
