The sequences that have a common difference of 2 are B and D, Option B and D both are correct.

Given that, determine the Which of the arithmetic sequence with common difference 2.

A. 1, −3, 5, −7, 9, …                B. 2, 4, 8, 16, 32, …
C. 10, 8, 6, 4, 2, …                 D. 13, 15, 17, 19, 21, …

Arithmetic progression is the series of numbers that have common differences between adjacent values.

Here,
A. 1, −3, 5, −7, 9, …

Common difference = -3 - 1 = -4

B. 2, 4, 8, 16, 32, …
Common difference = 4 - 2 = 2

C. 10, 8, 6, 4, 2, …
Common difference = 8 - 10 = -2

D. 13, 15, 17, 19, 21, …
Common difference = 15 - 13 = 2

Thus, the sequences that have a common difference of 2 are B and D, and Option B and D both are correct.

Answer:

1) The frequency of the light is approximately 4.283 × 10¹⁴ Hz

2) The color of the light is red

Step-by-step explanation:

1) The given parameter;

The wavelength of the line contained in the Neon spectrum, λ = 700 nm = 0.0000007 m = 7.0 × 10⁻⁷ m

The speed of light, v = 299,792,000 m/s

v = f × λ

The frequency, f of the light = v/λ = 299,792,000/(7.0 × 10⁻⁷) ≈ 4.283 × 10¹⁴ Hz

The frequency of the light ≈ 4.283 × 10¹⁴ Hz

2) Given that light with wavelength between 620 - 750 nm constitute red light, we have that the given light with a wavelength of 700 nm is a red light source.

Answer:

9

Step-by-step explanation:

Answer:

9/6 or 1 1/2

Step-by-step explanation:

For this problem. We need to add the following fractions:

2/3 and 5/6.

Let's find common denominators:

(Multiply 2/3 by 2/2)

= 4/6

Add the numerators:

[tex] \frac{4}{6} + \frac{5}{6} = \frac{9}{6} [/tex]

9/6 can also equal 1 1/2 as a simplified mixed fraction.

Step-by-step explanation:

Answer:

You are correct, the answer is (y=3)=-2(x-8)

Step-by-step explanation:

For this problem, let's first make the equation of the perpendicular line be in slope intercept form. Add 4y to both sides.

2x=4y+7

Subtract 7.

2x-7=4y

And divide by 4.

y=1/2x7/4

Here, the slope is 1/2, so the slope of the perpendicular line is the negative reciprocal, or -2.

Finally, substitute the given point into the point slope formula to get (y+3)=-2(x-8)

Answer:

The correct option is D.

Step-by-step explanation:

Let x denote the years.

The information provided is:

From the provided data derive the equation for the population of Smallville x years after as follows:

[tex]Y = [\frac{1}{2}\cdot (7420-152x)]-1200[/tex]

The population of Smallville is 2282 after x years.

Compute the value of x as follows:

[tex]2282= [\frac{1}{2}\cdot (7420-152x)]-1200[/tex]

[tex]\frac{7420-152x}{2}=2282+1200\\\\7420-152x=3482\times 2\\\\152x=7420-6964\\\\152x=456\\\\x=3[/tex]

Thus, the time it will take for Smallville's population to reach 2282 is 3 years.

The correct option is D.

Answer:

I believe the answer will be $77.

Step-by-step explanation:

This is percentages so we need to move the decimal in the 10 percent to the left 2 times. This will leave us with 0.10. We need to multiply this with 70. The equation will be 70x0.10= 7. Finally, you add this answer with the original number(70). Thus, the final answer will be $77.

Sorry dunno

Answer:

131

Step-by-step explanation:

Given that:

Median of a consecutive odd integers = 138

Greatest integer In dataset = 145

Least integer in dataset =

Since the integers are consecutive ;

Number of integers to greatest integer value : Greatest integer - median value = 145 - 138 = 7

Hence, 7 integers before the median value should give us the least integer value ;

138 - 7 = 131

CHECK:

131,132,133,134,135,136,137,138,139,140,141,142,143,144,145

Median = (n+1)/2 th term

Median = (15+1)/2 = 8th term = 138

Highest = 145

Least = 131
