Answer 2

Find BD

Remember soh-cah-toa?

opposite/adjacent

tan30=400/x

xtan30=400

x = 400/tan30

Find BC

Still toa. . . still toa

90 + 60 = 150

180-150 = 30

BAC = 30

tan30=x/400

400tan30=x

BD-BC=CD

If you followed my steps, your answer should come to you.

If you didn't and are a lazy pr*ck who relies on others to do their semester exam problems for them, the answer is A.  Or 461.

Step-by-step explanation: you would do +3x on both sides with out doing it to the 4y and the. You would get 4y =23+3x and then you divide everything by 4 even the 4y and then you would get y= 23/4 + 3/4x and then you put it into desemos and it will give you it graphed

The cost for an order of 100 kilograms of steel bars is $230. The cost for an order of 150 kilograms of steel bars is $320. Write an equation for the cost of an order of steel bars (y) in terms of the weight of steel bars ordered (x). Show or explain how you found your equation.

Answers

Answer:

y = 9x/5 + 50

Step-by-step explanation:

We are represent the information as coordinate (x,y)

If the cost for an order of 100 kilograms of steel bars is $230, this is expressed as (100, 230)

Also if the cost for an order of 150 kilograms of steel bars is $320, this is expressed as;

(150, 320)

Find the equation of a line passing through the points. The standard form of the equation is expressed as y = mx+c

m is the slope

c is the intercept

Get the slope;

m = y2-y1/x2-x1

m = 320-230/150-100

m = 90/50

m = 9/5

Get the y-intercept by substituting m = 9/5 and any point say (100, 230) into the expression y = mx+c

230 = 9/5(100)+c

230 = 9(20)+c

230 = 180 + c

c = 230-180

c = 50

Get the required equation

y = mx+c

y = 9/5 x + 50

Hence an equation for the cost of an order of steel bars (y) in terms of the weight of steel bars ordered (x) is y = 9x/5 + 50

Answers

To see if it is possible, you will want to create an equation.

3(4x+2) = 6(2x+2)

As you can see, you will need to use the distributive property for this equation.

12x + 6 = 12x + 12

Remove 6 from both sides.

12x = 12x + 6

Divide 12 by both sides

x = x + 0.5

Because the answer wasn't x = x, the two plants won't ever be the same height. Even if you tried to subtract 0.5, you'd only get a negative 0.5 on the other side.

Enter the value for x that makes the equation 1/2 (4x – 8) + 3x = 36 true.

Answers

Answer:

x = 8

Step-by-step explanation:

1/2(4x – 8) + 3x = 36

~Simplify left side

2x - 4 + 3x = 36

~Combine like terms

5x - 4 = 36

~Add 4 to both sides

5x = 40

~Divide 5 to both sides

x = 8

Which polynomial can be factored using the binomial theorem?

1,000x3 – 2,800x2 + 1,960x – 343

Answers

Answer:C

Step-by-step explanation:

The polynomial can be factored using the binomial theorem is

1,000x³  – 2,100x² + 1,470x – 343.

What is Binomial Theorem?

Assertion that the sum of the nth power of the product of two positive integers a and b may be written as the sum of the n + 1 terms of the form for any positive integer n.

If a and b are real numbers and n is a positive integer, then

[tex](a + b)^n =^nC_0 a_n + ^nC_1 a_{n-1} b_1 + ^nC_2 a_{n-2} b_2 + ... 1.[/tex]

Given:

Using Binomial we can write

(a+ b)³ = a³ + b³ + 3a²b + 3ab²

and, (a+ b)² = a² + 2ab + b²

So, 100x²+ 70x + 49 and 100x² + 210x + 49 cannot be factors using Binomial Theorem because the correct expansion would be

(10x+ 7)² = 100x² + 140x + 49

and, 1,000x³  – 2,100x² + 1,470x – 343 can be factored using Binomial theorem.

As, (10x - 7)³ = 1000x³ -2100x² + 1470x - 343.

Answers

Answer:

$3000

Step-by-step explanation:

If the remainder is spent on other costs, then that means 60% of the tuition as spent on other costs.

To find the total tuition, divide 1800 by 0.6:

1800/0.6

= 3000

What is geometric transformation?

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

We have a point 'p' which is a fixed point.

Triangle ABC is rotated about the 'p' point such that the new location of A, B, and C becomes A', B', and C'.

The new triangle formed is triangle A'B'C'.

From the figure, we can clearly see that the angle APA' is a right-angle triangle.

m∠APA' = 90°

Thus, the value of angle APA' is 90°.
