What is the first step in simplifying the expression (2-3•4+5)^2 ?
(1) square 5
(2) add 4 and 5
(3) subtract 3 from 2
(4) multiply 3 by 4

Answers

Answer 1
The answer is (4)- multiply 3 by 4.

The following is the correct order of steps to simplify an expression.

1.) Parenthesis
2.) Exponents
3.) Multiply and Divide left to right
4.) Add and Subtract left to right.

Since there are parenthesis in the expression, you must do whatever is inside before anything else.

Inside the parenthesis, there is a subtraction, multiplication, and addition. Since multiplication comes before addition and subtraction in the order of operations, you must do that first. Therefore, the correct answer is multiply 3 by 4.
Answer 2

Answer:

(4) multiply 3 by 4

Step-by-step explanation:

(2-3•4+5)²

Firstly multiply 3 by 4

(2-12+5)²

Then add 2 and 5

(-12+7)²

Now subtract -12 from 7

-5²

= (-5)(-5)

= 25

Thus, the first step in simplifying the expression (2-3•4+5)^2 is (4) multiply 3 by 4.

Answer:

x=9

Therefore angles 7x-4 = 6x-4 = 59 degree

Step-by-step explanation:

7x-4 = 6x-4    Findings; alternate angles

                      Although any coefficient angles can be set = to each other.

7x-6x-4 = +5  Subtract 6x from both sides

x -4 = 5

x = 5+4           Add 4 to each side

x = 9

Find the angle degree

6(x) + 5 = 7(x) - 4    Plug 9 in to x

6(9) + 5 = 7 (9) - 4

54 + 5 = 63-4

59 = 59

x = 59 degree.

Slope= 9, (-5,2)

Answers

If an equation had a slope of 9 and went through the point (-5, 2) then the equation would be:

y = 9x + 47

Explanation: slope intercept equation is represented by y = mx + b. M represents slope and B represents the y-intercept (which is the place where the graph crosses the y-axis.) So using the info we know about the graph going through (-5, 2) and that the slope is 9 (or m = 9) then we could determine that the y-intercept is 47. Now, using everything we have found thus far, we can fill in the slope intercept equation.

What is cos(338)? Solve by hand, no calculator.
Correct answer gets BRAINLIEST.

Answers

9514 1404 393

Answer:

  0.927184

Step-by-step explanation:

Assuming you want cos(338°), it is equal to cos(22°). This value is an irrational root of a 26th-degree polynomial. (Neither the polynomial, nor the root are easy to find by hand.)

The values of trig functions for 30° and 45° are well-known, as are half-angle and angle sum/difference formulas. The nearest angle for which cosine is relatively easy to find is 22.5°. A 2nd-order Maclaurin series expansion of the cosine function about that angle gives the approximation ...

  cos(x) ≈ cos(π/8)(1 -π²/128) +π/8·sin(π/8) +(π/8·cos(π/8) -sin(π/8))x -1/2·cos(π/8)x²

For your angle of 22°, the value of x needed in this expression is 11π/90. The values of cos(π/8) and sin(π/8) are the irrational numbers ...

  cos(π/8) = √(2 +√2)/2 ≈ 0.92387953

  sin(π/8) = √(2 -√2)/2 ≈ 0.38268343

If you use the approximation pi ≈ 355/113, both for the above formula and for the angle of interest, this reduces to the sum ...

  cos(22°) ≈ 71√(2-√2)/16272 +132383951√(2+√2)/264777984

This would be tedious to calculate by hand, but is not impossible. The value this sum produces will be correct when rounded to 7 decimal digits.

__

Before calculators, trig function values were found in published tables. These days, tables are available on-line. Previously, they were published in books, usually along with information that helped with interpolation between table values, when necessary. The attachment shows a portion of an online cosine table suitable for answering your question.

_____

Additional comment

Before calculators, mathematicians spent lifetimes calculating accurate trig tables. For all but a very few angles, the cosine function of rational degree values will be an irrational number, as it is for cos(22°).

at what ordered pair do the lines x=4 and y=-3 intersect?

Answers

x = -4 is a vertical line. The x-coordinate will always stay the same regardless of any y-coordinate paired with it.

y = -3 is a horizontal line. Similarly, the y-coordinate will always stay the same regardless of any x-coordinate paired with it.

Therefore, they will intersect at point (4, -3).

now, let's plug the value of slope (m) and coordinates of point (3 , -2) to find c (y - intercept)

[tex]y = mx + c[/tex]

Suppose the value of x varies from x = a to x = b . There are at least two ways of thinking about what percent x changed by. We'll explore two of them here. For each of the following questions, write an expression in terms of a and b to answer the question. Method 1 b is how many times as large as a ? times as large Therefore, b is what percent of a ? % Hence, if x varies from x = a to x = b , x changes by what percent?

Answers

The change in the value of x, as a percentage, is given by:

[tex]\frac{b - a}{a} \times 100\%[/tex]

The percentage change is given by the change multiplied by 100% and divided by the initial value.

In this question, x varies from [tex]x = a[/tex] to [tex]x = b[/tex], which means that the initial value is a, and the change is b - a. Then, the percentage chance in the value of x is given by:

Answers

Line segment of length k is divided into 3 equal parts.

so first segment is 0-k/3 and third segment is 2/3k-k

so mid-pt of 1st = k/6 and 3rd = 5/6k

so the distance in between = 5/6k-k/6 = 4/6k = 2/3k

7. A caterer knows there is one broken egg in every 3 cartons. A carton contains 12 eggs.
A caterer plans to serve 1200 eggs. What is the best estimate the number of cartons the caterer should buy?

Answers

9514 1404 393

Answer:

  103

Step-by-step explanation:

For 1200 eggs, the caterer needs ...

  (1200 eggs)/(12 eggs/carton) = 100 cartons

of unbroken eggs.

The rate of broken eggs is 1 in 3×12 = 1 in 36, so the caterer must buy 36 eggs for each 35 unbroken eggs delivered.

Then the number of cartons that must be purchased is ...

  (100 cartons)(36/35) = 102 6/7 cartons

The caterer should buy 103 cartons of eggs.
