Answer:

  3.0

Step-by-step explanation:

The angle, its opposite side, and the hypotenuse are given. Then the relevant trig relation is ...

  Sin = Opposite/Hypotenuse

  sin(21°) = x/8.3 . . . . . . . . . . . . . . . . . . use the given values

  x = 8.3·sin(21°) ≈ 8.3×0.3584 . . . . . . multiply by 8.3

  x ≈ 3.0

Answer:

D. The slope of f(x) is less than the slope of g(x).

Step-by-step explanation:

✔️Slope of f(x):

Using two points on the line, (0, 2) and (1, -1),

Slope (m) = change in y/change in x

Slope (m) = (-1 - 2)/(1 - 0) = -3/1 = -3

Slope of f(x) = -3

✔️Slope of g(x) = -5x - 6:

The slope of g(x) is -5.

Therefore f(x) has a lesser absolute slope value (3) compared to the absolute slope value of g(x) (5).

Thus, D. the slope of f(x) is less than the slope of g(x).

Answer:

  (x, y) = (2, 5)

Step-by-step explanation:

Substitute the expression for y in the second equation into the first equation:

  5x -5 = x +3

  4x = 8 . . . . . . add 5-x to both sides

  x = 2 . . . . . . divide by 4

  y = 2+3 = 5 . . . substitute for x in the first equation

The solution is (x, y) = (2, 5).

[tex]\cos(30) = \frac{\sqrt3}{2}[/tex]

Step-by-step explanation:

Exact value of [tex]\cos(30)[/tex]

[tex]\cos(30)[/tex] is calculated from an equilateral triangle, divided into with the following dimensions

[tex]Hypotenuse = 6[/tex]

[tex]Adjacent = 3[/tex]

[tex]Opposite = 3\sqrt 3[/tex]

So:

[tex]\cos(30) = \frac{3\sqrt3}{6}[/tex]

Answer:

A(t)  =  27.86 in²

Dimensions of the paper:

L =  3.73 in

w = 7.47 in

Step-by-step explanation:

The total area of a rectangular page  A  = ( x + 2)* (y + 4 )         x  is the length and  y the wide. x  and  y  are the dimensions of the print area

The print area of the paper is  A =  6 in²       6 = x*y     y  =  6/x

Then print area as a function of x is

A(x)  =  ( x + 2 ) * ( 6/x + 4 )    ⇒  A(x)  =  6  +  4*x  + 12/x + 8

Taking derivatives on both sides of the equation:

A´(x)  =  4  - 12/x²        A´(x)  =  0     4  =  12 /x²

x²  = 12/4       x =√3    x  =  1.73  in  and   y  =  6 / 1.73

y  =  3.47 in

Then the dimensions of the paper  are.

Length  L =  x  + 2  = 3.73 in      and   w  =  3.47 + 4  = 7.47 in

And the least amount of paper is

A(t)  =  3.73* 7.47  =  27.86 in²

To find out if x = 1.73 is an x coordinate for a minimum we get the second derivative

A´´(x)  =  24/x³    is always positive   A´´(x) > 0  then we have a minimum for A at  x = 1.73

Answer:

you would pay $11.04

Step-by-step explanation:

$12 x .08= .96

$12 - 0.96 = $11.04

Answer:

11.04

Step-by-step explanation:

So, a ticket cost 12$.

We need to find the price when it of 8% off, whihc is tecnically 92% of the orginal price.

Putting this into decimal form:

0.92

So to find this price, we need to multiply the orginal price by the percentage:

12*0.92

0.02*12 is 2*24 adding 2 decimals which equals 0.24

0.9*12 is 12*9 adding 1 deecimal which equals 10.8

Add them together: 0.24+10.8 = 11.04

So 11.04 is our new cost.

Hope this helps!

Answer:

m = - 2/3 or

m = - 0.66667.

I don't know which form is simpler.

Step-by-step explanation:

All you want is the slope.

The slope formula is

m = (y2 - y1) / (x2 - x1)

y2 =  7

y1 = 3

x2 = - 2

x1 = 4

My choice of which one is 1 and which one is 2 is totally arbitrary. You could have made y2 = 3 and y1 = 7 and x2 = 4 and x1 = -2

m = (7 - 3) / (-2 - 4)

m = 4 / - 6

m = -2/3 or

m = - 0.6667

Explanation:

sum -- the result of addition: 5x+1

term -- a constant, variable, or product of a constant and one or more variables. In the more general sense, a term is any part of the expression that can be considered by itself. An example is 5x

product -- the result of multiplication: 9(5x+1), where 9 is multiplied by the sum (5x+1)

factor -- part of a product: x

quotient -- the result of division: 9(5x+1)÷3

coefficient -- a constant, or the constant that multiplies the variables in a term: 5

Additional comment

The way this is written, there will be the tendency to think of 3y as a term in the same sense that 5x is a term. That would be incorrect. The Order of Operations has you interpret this expression as ...

Answer: $2.40

Step-by-step explanation:

You would multiply 12 by 20 which would give you $2.40.

The price of the 20 rolls will be equal to 48 cents.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that In Haiti, the price for five (5) flat rolls is 5 gourdes, around 12 cents.

The cost of the 20 rolls will be calculated as,

20 rolls ⇒ 12 cents

1 roll ⇒ 12 / 20 cents

20 rolls ⇒ ( 12 x 20 ) / 20

20 rolls ⇒ 48 cents

Therefore, the price of the 20 rolls will be equal to 48 cents.

a) Null Hypothesis: length of each screw is less than 14 centimeters

b) Alternate Hypothesis: length of each screw is equal to or greater than 14 centimeters

Step-by-step explanation:

Complete question

A factory that manufactures screws is performing a quality control experiment. Each object should have a length of no more than 14 centimeters. The factory believes that the length of the screws exceeds this value and measures the length of screws. The sample mean screw length was centimeters. The population standard deviation is known to be centimeters.

1. What is the null hypothesis?

2. What is the alternative hypothesis?

Solution :

The null hypothesis is basically the problem statement that needs to be tested.

Alternate hypothesis is opposite of that of null hypothesis

a) Null Hypothesis: length of each screw is less than 14 centimeters

b) Alternate Hypothesis: length of each screw is equal to or greater than 14 centimeters
