Answer:

It's 63.75 since I looked it up.

The frequency of red light is 4 x 10¹⁴ Hz. The correct answer is option D.

Scientific Notation is a way of writing down in the easy form of very large or very small numbers.

The given that when the frequency of an electromagnetic wave is 400,000,000,000,000 Hz, it results in red light.

The choices given are in scientific notation form, where the coefficient is multiplied by 10 raised to a certain power of 10.

To convert 400,000,000,000,000 Hz into scientific notation, we need to move the decimal point 14 places to the left to obtain a coefficient between 1 and 10.

This gives us 4.0 as the coefficient, and since we moved the decimal point 14 places to the left, the power of 10 is -14.

Therefore, the frequency of red light is 4 x 10¹⁴ Hz.

Answer: JK

Step-by-step explanation:

Answer:

$13.67

Step-by-step explanation:

Let's say that CD= c and DVDs= d. Four CDs and 4 DVDs cost $164, so the equation will be:

i.  4c + 4d= 164

The cost of the 4 CDs is half the cost of the  4 DVDs, to put into an equation it will be:

ii.   4c= 0.5(4d)

     4c= 2d

     d= 2c

Then we can substitute the second equation (ii) into the first equation (i). The calculation will be:

4c + 4d= 164

4c + 4(2c)= 164

4c+ 8c= 164

12c= 164

c=13.67

The cost for each CD is $13.67

Thanks for the question!

When rounded to two decimal places, 89 divided by 3 is approximately 29.67.

To calculate 89 divided by 3 in decimal form, we perform the division operation:

89 ÷ 3 ≈ 29.666666...

The division result is a repeating decimal with the digit 6 repeating infinitely. However, since you asked for the answer in decimal form, rounded to a certain number of decimal places, we can round the result to a reasonable precision.

Let's round it to two decimal places:

89 ÷ 3 ≈ 29.67

So, when rounded to two decimal places, 89 divided by 3 is approximately 29.67.

Answer:

-5/2

Step-by-step explanation:

Since they are both parallel they have the same rate of change. this means they have the same slope

Final answer:

Since line w is parallel to line v, which has a slope of -5/2, the slope of line w is also -5/2.

Explanation:

When two lines are parallel, they have the same slope. In this case, the slope of line w will be the same as the slope of line v.

Therefore, the slope of line w is -5/2.

The question asks about the slope of two parallel lines. By definition, parallel lines have the same slope. Given that line v has a slope of -5/2, and line w is parallel to line v, the slope of line w must also be -5/2. Therefore, line w, being parallel to line v, has a slope of -5/2.

Answer:

x^2+36 or x2 + 36 = 0

Step-by-step explanation:

Answer:

x> 6 twice

Step-by-step explanation:

x^2+36>12x

x² + 36 > 12x

Collect like terms

x² - 12x + 36 > 0

Solve quadratically using factorisation method by finding two factors of 36 that when added gives -12, the coefficient of x.

Factors = -6 and -6 which both add up to -12

Rewrite equation

x² - 6x - 6x +36> 0

Factorise by taking out the common factor

x ( x - 6) -6( x - 6) > 0

(x -6)(x - 6) > 0

x - 6 > 0 or x -6 > 0

Add 6 to both sides

x -6+6> 0+6 or x-6+6>0+6

x > 6  or x> 6

x> 6 twice

Answer:

791.2 ft

Step-by-step explanation:

The cable is inclined and this acts as the hypotenuse. Since the other two sides are given.

[tex]H=\sqrt {x^{2}+y^{2}}[/tex]

where x and y represent the distance between two cliffs apart and difference in heights. Substituting 740 for x and 280 for y then

[tex]H=\sqrt {740^{2}+280^{2}}=791.20161779409930627669981858168023442712 ft\approx 791.2 ft[/tex]

Answer:

791.2 ft to the nearest tenth.

Step-by-step explanation:

From the diagram,we assume :

AD to be the height of the first cliff

BC to be the height of the second cliff

DC to be the length of the cable between the top of the two cliff.

AD=740 ft.

DE= 280 ft.

Using Pythagorean Theorem, we obtain.;

[tex] {DE}^{2}+ {CE}^{2} = {DC}^{2} [/tex]

By substitution we obtain

[tex] {280}^{2} + {740}^{2} = [/tex]

[tex] \implies78400 + 547600 = {DC}^{2} [/tex]

[tex]\implies626000= {DC}^{2} [/tex]

Taking positive square root.

[tex]\implies DC = \sqrt{626000} [/tex]

Without additional context or details about how JK, JL, and JM are related, it's impossible to accurately calculate or deduce the value of JM. Further clarification or more information about the scenario or the mathematical or geometric principles involved is needed for a precise answer.

The question provided does not seem to present enough context or connection to standard mathematical operations or geometric principles that would enable a straightforward calculation or deduction of the value of JM. Without additional information about the relationship between JK, JL, and JM (such as whether they are sides of a triangle, or represent values in a given mathematical formula), or without a clear mathematical or geometric context, it's impossible to accurately determine the value of JM.

Generally, in mathematics, when calculating distances or values based on given lengths, one needs to apply specific formulas or theorems (such as the Pythagorean theorem in the context of right-angled triangles, or vector addition in the context of physics problems). Unfortunately, the given data lacks the necessary context to apply such principles.

For a precise and accurate answer, I recommend clarifying the problem's context or providing more details about the scenario in which JK, JL, and JM are related.

-Final answer:

To find JM in a triangle with known side lengths JK = 7 and JL = 12, we use the Triangle Inequality Theorem to determine that JM must be less than 19.

Explanation:

To find JM, we can use the fact that in a triangle, the sum of the lengths of any two sides must be greater than the length of the third side (Triangle Inequality Theorem).

JK + JL > JM

7 + 12 > JM

19 > JM

Therefore, JM must be less than 19 but more than the absolute difference of JK and JL, so JM < 19.

Answer:

The student is wrong, the total area = 16 ft² + 20 ft²

Step-by-step explanation:

The figure can be consists of :

1) A square of side length of 4 ft

2) A trapezoid of height (8-4 = 4 ft) and the bases length is (6 and 4 ft)

So,

The area of the square = 4 * 4 = 16 ft²

The area of the trapezoid = 0.5 (6+4) * 4 = 5 * 4 = 20 ft²

So ,the total area = 16 + 20 = 36 ft²

So,

The student is distracted.

he have found the area of total rectangle of length of 8 ft and width of 6 ft instead of the area of the trapezoid.

Answer:

8.8

Step-by-step explanation:

if you use the sin, cos, and tan method. 20 is the h, x is the a and the blank side is the o. if you take way the side without the o you have the a and h which means you have cosine. If you did the equation as cos64=x/20 Then multiply both sides by 20 to get the X by it so you will have 20 COS 64 and once you want a play that together you have 8.8 equals X.

Answer:

17.5

Step-by-step explanation:

35% = 0.35 in decimal form.

(Think about: 1 = 100%)

To find 35% of 50, we simply multiply.

0.35 × 50 = 17.5

35% of 50 is 17.5

Well, since the graph starts at (0,50), making our y-intercept 50, we can knock off D as an option.

The next step is to find the slope. To do this, find two points and subtract the y values over the x values. (Just make sure that whichever y value you start with - start with the same x value).

So we have >>> (50, 200) and (0,50) from earlier.

200 - 50 / 50 - 0 = 150/50 or 3/1, or 3.

This makes the correct answer A since the equation is represented as y = mx + b, where m is the slope and m has a value of 3.

The domain of the function h(x) = √(x-10) is all real numbers x that are greater than or equal to 10, because we cannot take the square root of a negative number under the real number system.

In mathematics, the domain of a function is the set of all the possible input values (usually denoted as x) that would lead to a real and defined output. As for the function h(x)=√(x-10), we have a square root operation involved. We know that under the real number system, we cannot take the square root of a negative number.

Hence, for the function h(x)=√(x-10) to be real and defined, (x-10) must be greater than or equal to 0. That is, x-10 ≥ 0. Solving for x, we get x ≥ 10.

Therefore, the domain of the function h(x) = √(x-10) is x≥10. That is, h(x) is defined for all real numbers x that are greater than or equal to 10.
