Pleaseeee help with this question

prove (1-cos^2A)csc^2A=1

Answers

Answer 1

For all x,

sin²(x) + cos²(x) = 1

so we have

(1 - cos²A) csc²A = sin²A csc²A

and since csc(x) = 1 / sin(x), so the expression reduces to 1.

How would you graph x > 0 on a number line?
А
Draw an open circle over 0, and shade the arrow to the right.
B
Draw a closed circle over 0, and shade the arrow to the right.
С
Draw an open circle over 0, and shade the arrow to the left.
D
Draw a closed circle over 0, and an open circle over 10.

Answers

Answer:

A

Step-by-step explanation:

The correct way to graph x > 0 on a number line is option B) Draw a closed circle over 0 and shade the arrow to the right.

In this case, the inequality x > 0 represents all values of x that are greater than zero. By placing a closed circle on zero, we include the value of zero in the solution set. The shading of the arrow to the right indicates that all values greater than zero are included in the solution.

Since the inequality is strict (x > 0), we use a closed circle to represent zero, indicating that zero is part of the solution set. An open circle would be used if the inequality was non-strict (x ≥ 0), excluding zero from the solution set. However, in this case, zero is included, so a closed circle is used.

Sandy bought a car for $17,500. Her monthly car payment is $346. The first month the amount applied to the principal is $283 and the interest amount is $63 Assume that each month the amount applied to the principal increases by $1 and the interest amount decrease by $1 Which spreadsheet shows the amount of interest she paid in the six months?

Answers

Answer:

I'm not quite sure how to point to which graph exactly, but I will tell you that it is the one that principal increases by one for six months, and interest decreases. It has "Month, Principal, Interest, and Total" written across the top in bold. Down the left-hand side, it has numbers 1-6. On the bottom, the first total is $363, and the second is $2076.

Step-by-step explanation:

There is very limited math involved in this question. The first step is to find a graph where each month, the principal number increases by one dollar and the interest decreases by one dollar. This should go on for six months. We can now eliminate two graphs. For a third, you must remember that the interest starts in the sixty, and the principal payment is in the two hundred eighties. By now, we have our graph. The final step to double-check this is to add up the total interest and principal (which should be on the side). All totals should be $346 as we're basically just trading one number for another (-1+1). You should also go to the bottom and fill in the blank in the principal column. In this box, you should put the total of all principals together.

After a bad break up, you decide to burn all the things a former boyfriend/girlfriend has given to you and any keepsakes. You have 50 items to put into the "pit" to burn. There are 85% of the items remaining at the end of 5 minutes. When will all your memories be gone?

Answers

Answer:

5.9 minutes

Step-by-step explanation:

85% of 50 items is gone in 5 minutes

42.5 items = 5 minutes

50 items = x minutes

42.5 items × x minutes = 50 items × 5 minutes

x = 50 items × 5 minutes/42.5 items

x = 5.8823529412 minutes

x ≈Approximately to 1 decimal place 5.9 minutes

Answers

The solution x > -3 represents all values of x that are greater than -3. On the other hand, the solution x = -3 represents a single value of x that is equal to -3.

Given that,

An equation is,

- 4(2x - 3) = 36

Here, Jake's solution to the equation - 4(2x - 3) = 36 is,

-4(2x - 3) = 36

Apply distributive property,

-8x + 12 - 36

- 8x + 12 - 12 = 36 - 12

Subtract 12 on both sides,

-8x = 24

x = - 24/8

x = - 3

So, the solution x = -3 represents a single value of x that is equal to -3.

Therefore, x > -3 represents a range of values greater than -3, while x = -3 represents a single value that is equal to -3.

You are ordering shirts for the math club at your school. Short-sleeved shirts cost $10 each. Long-sleeved shirts cost $12 each. You have a budget of $300 for the shirts. The equation $10x+12y=300$ models the total cost, where $x$ is the number of short-sleeved shirts and $y$ is the number of long-sleeved shirts. a. Graph the equation. Interpret the intercepts

Answers

Answer:

a. i) Please see the  included graph of the equation $10·x + $12·y = $300

ii) The intercepts give the maximum number of either short-sleeve (x-intercept) long-sleeved (y-intercept) that can be ordered

Step-by-step explanation:

The given information are;

The cost of each short-sleeved shirt = $10

The cost of each long-sleeved shirt = $12

The amount available in the budget = $300

The equation for the total cost = $10·x + $12·y = $300

Where;

x = The number of short-sleeved shirts

y = The number of long-sleeved shirts

Rewriting the equation given in slope and intercept form, we have;

$10·x + $12·y = $300

$12·y = $300 - $10·x

y = $300/$12 - $10·x/$12

y = 25 - 5/6·x

Please find attached, the graph of the equation made with Microsoft Excel

The values of the data that can calculated to plot the graph are;

x, y

(0, 25 )

(5, 20.83 )

(10, 16.67)

(15, 12.5 )

(20, 8.33)

(25, 4.17)

(30, 0 )

The x-intercept gives the number of short-sleeve shirts that can be purchased with the $300 available budget, while the y-intercept gives the number of short-sleeve shirts that can be purchased with the $300 available budget.

The graph of the equation is shown below.

The x-intercept is at point (30,0), which means the number of short-sleeved shirts is 30 when the number of long-sleeved shirts is 0.

The y-intercept is at point (0,25), which means the number of long-sleeved shirts is 25 when the number of short-sleeved shirts is 0.

Given:

Short-sleeved shirts cost $10 each.  

Long-sleeved shirts cost $12 each.

The total budget is $300.

The given equation is:

[tex]10x+12y=300[/tex]

where [tex]x[/tex] is the number of short-sleeved shirts and [tex]y[/tex] is the number of long-sleeved shirts.

To find:

The graph of the given equation and the interpretation for the intercepts.

Explanation:

We have,

[tex]10x+12y=300[/tex]

Substitute [tex]x=0[/tex].

[tex]10(0)+12y=300[/tex]

[tex]12y=300[/tex]

[tex]y=\dfrac{300}{12}[/tex]

[tex]y=25[/tex]

So, the y-intercept is at point (0,25).

Substitute [tex]y=0[/tex].

[tex]10x+12(0)=300[/tex]

[tex]10x=300[/tex]

[tex]x=\dfrac{300}{10}[/tex]

[tex]x=30[/tex]

So, the x-intercept is at point (30,0).

Plot the points (30,0) and (0,25) on a coordinate plane and connect them by a straight line.

The x-intercept is at point (30,0), which means the number of short-sleeved shirts is 30 when the number of long-sleeved shirts is 0.

The y-intercept is at point (0,25), which means the number of long-sleeved shirts is 25 when the number of short-sleeved shirts is 0.

8k - 48 + 58 = 8k + 10 , that is

8k + 10 = 8k + 10

Answers

Answer:

m∠C = 56 and (4x + 16) = 180

Step-by-step explanation:

The sum of angle in a triangle is 180, hence:

<A+<B+<C = 180

Given

<A = 2x+1

<B = x

<C = x+15

Substitute

2x+1+x+x+15 = 180

collect like terms:

2x+x+x+1+15 = 180

4x+16 = 180

4x = 180-16

4x = 164

Divide both sides by 4

4x/4 = 164/4

x = 41°

Since <A = 2x+1

<A = 2(41)+1

<A = 82+1

<A = 83

<B = x = 41

<C = x+15

<C = 41+15

<C = 56

Based on the calculation above, the true statements are:

m∠C = 56 and (4x + 16) = 180
