Answer:

n=-31/2 or -15 1/2

Step-by-step explanation:

reduce the numbers

2*n+17/4=3/8

n+17/4=3/8

8(n+17) =17

8n+136 =12

8n=12-136

8n=-124

Answer:

A) [tex]\frac{1+sin(x)+1-sin(x)}{1-sin^2(x)}=\frac{2}{cos^2(x)}[/tex]

Step-by-step explanation:

By combining the fractions on the left side into one fraction, we have:

[tex]\frac{1}{1-sin(x)}+\frac{1}{1+sin(x)}=\frac{2}{cos^2(x)}\\ \\\frac{1+sin(x)+1-sin(x)}{(1-sin(x))(1+sin(x))}=\frac{2}{cos^2(x)}\\\\\frac{1+sin(x)+1-sin(x)}{1-sin^2(x)}=\frac{2}{cos^2(x)}[/tex]

Also, given the Pythagorean Identity [tex]sin^2(x)+cos^2(x)=1[/tex], then [tex]cos^2(x)=1-sin^2(x)[/tex].

Answer:

f(x)=2x−5 if x≤−3

Since the value of x is -3, the first function will be the correct option.

Step-by-step explanation:

The given function is -

f(x)=2x−5 if x≤−3

f(x)=−3x+4 if x>−3

Now we have to evaluate f(-3).

Since we have to calculate the value of f at x = -3, we have to choose the first function.

That is f(x) = 2x - 5.

Hence,

f(−3)=2∗(−3)−5=−6−5=−11

Therefore we have the value

f(−3)=−11

Since the domain of the function is divided into two parts, we have to choose any one function for a given value of x,

For values of x less than or equal to -3, we will use the first function. That is,

f(x)=2x−5 for all x∈(−∞,−3]

And for values of x greater than -3, we will use the second function. That means,

f(x)=−3x+4 for all x∈(−3,∞)

Answer:

i think it is 1/26

Step-by-step explanation:

Answer:

[tex]\frac{1}{26}[/tex]

Step-by-step explanation:

There are 26 letters in the alphabet. The computer chooses randomly, so everytime it picks a letter, out of all the 26 there is only one first letter of your name.

So, there should be a

[tex]\frac{1}{26}[/tex]

chance that the first letter in your name will be picked.

The scale factor is what you multiply the sides by. Dilate means wider or larger so you multiply each side by the scale factor of 2 to get the higher scaled rectangle.

Answer:

area:39

Step-by-step explanation:

Answer:

  a) rise 5, run 5, slope 1

  b) rise 10, run 5, slope 2

Step-by-step explanation:

The rise is the vertical difference between the points. It is the length of the vertical side of the triangle you have drawn. You can determine that length by counting grid squares or by finding the difference of the y-coordinates of the points.

The run is the horizontal difference between the points. It is the length of the horizontal side of the triangle you have drawn. You can determine that length by counting grid squares or by finding the difference of the x-coordinates of the points.

rise = 5; run = 5. (counting grid squares)

slope = rise/run = 5/5 = 1

__

rise = 10; run = 5. (taking coordinate differences: 5-(-5) = 10; 4-(-1) = 5)

slope = rise/run = 10/5 = 2

Answer:

a. $70.43

b. 23.43 + 13.92 + 32.98 = t (UNSURE)

Step-by-step explanation:

Since Mrs. Thomas is driving 231 miles using 23 miles per gallon, let's start by dividing 231 by 23

[tex]\frac{231}{23} = 10.043....[/tex]

We need to round 10.043... to 11 because you can't get part of a gallon.

Now, we need to multiply 2.13 by 11 to get the total amount of money for gasoline.

[tex]11 * 2.13 = 23.43[/tex]$

We also have the aditional meal expenses, which are $13.92 and $32.98.

We can use an equation to solve. Our total amount will be represented by t.

[tex]23.43 + 13.92 + 32.98 = t[/tex]

[tex]t = 70.43[/tex]

Hope this helps! Part b seems a bit confusing. I'll fix my answer if you could clarify, like if I do "communative property" or write equation. :))

Answer:

y=2x-1

Step-by-step explanation:

The equation for a line (slope-intercept form) is:

y=mx+b

m: slope

b: y-intercept

x and y: (x, y) coordinate pair

In this scenario, since we are given the slope and a point on the line, we can solve for the y-intercept:

y=2x+b

5=2(3)+b

5=6+b

Subtract 6 from both sides

b=-1

Therefore the equation of the line is:

y=2x-1

The Simplified polynomial expression in the standard form which represents the area of the given rectangle  is,

[tex]2x^2+6x-8[/tex]

The area of rectangle is the product of its length and width. It can be given as,

[tex]A=a\times b[/tex]

Here, (a) is the length of the rectangle and (b) is the width of the rectangle.

Given information-

One side of the rectangle is labeled as 2x-2.

Another side of the rectangle is labeled as x+4.

The image of the rectangle is attached below.

Let (l) is the length of the rectangle and (w) is the width of the rectangle.

In the below image, the length of the rectangle is,

[tex]l=4x+2[/tex]

The width of the rectangle is,

[tex]w=2x-2[/tex]

The area of the rectangle is the product of its length and width. Thus the area of the given rectangle is,

[tex]A=l\times w\\[/tex]

Put the values in the above expression as,

[tex]A=(x+4)\times(2x-2)\\A=2x^2+8x-2x-8\\A=2x^2+6x-8[/tex]

Thus the area of rectangle in simplified polynomial expression in the standard form is,

[tex]2x^2+6x-8[/tex]

The cost of purchasing the number of shirts after discount and sale tax is $40.3125.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

The discount is 25%.

The total price before the coupon is $50.

The sale tax is 7.5%

The cost of purchasing the number of shirts after discount will be

[tex]\rm Cost = 50*(1-0.75 )\\\\Cost = 97.5[/tex]

The cost of purchasing the number of shirts after the sale will be

[tex]\rm Cost = 37.5*(1.075)\\\\Cost = 40.3125[/tex]

The cost of purchasing the number of shirts after discount and sale tax is $40.3125.
