How would I do fractions for common difference for each arithmetic sequence?

1 answer:

6 0

In an arithmetic sequence, you add or subtract a fixed amount called the common difference to be able to get the next term in the sequence.

The first step in solving an arithmetic sequence containing fractions, you subtract the first term from the second term to get the common difference.Then using this common difference you find the nth term asked.

The number of bees spotted in Amelie's garden can also be modeled by the function √ B(x) = 50 k + 2x where x is the daily high t

uranmaximum [27]

Answer:

According to this model, the rate of increase of bees spotted with respect to time when 100 bees are spotted = 80 bees per day.

Step-by-step explanation:

√B(x) = 50 k + 2x

where x is the daily high temperature, in degrees Farenheit.

k is a positive constant.

When the number of bees spotted = 100,

The daily high temperature is increasing at a rate of 2°F per day; (dx/dt) = 2 °F/day

How quickly is the number of bees changing with respect to time when 100 bees are spotted?

√B(x) = 50k + 2x

Taking a time derivative of both sides,

(d/dt) [√B] = (d/dt) [50 k + 2x]

(1/2) (B⁻⁰•⁵) (dB/dt) = (d/dt)(50k) + (d/dt)(2x)

½(B⁻⁰•⁵) (dB/dt) = 50 (dk/dt) + 2 (dx/dt)

B = 100 bees

(dB/dt) = ?

(dk/dt) = 0 (since k is a positive constant)

(dx/dt) = 2°F/day

½(100⁻⁰•⁵) (dB/dt) = 50 (0) + 2 (2)

½(10⁻¹) (dB/dt) = 4

(1/2)(1/10) (dB/dt) = 4

(dB/dt) = 4×2×10 = 80

(dB/dt) = 80 bees per day

Hope this Helps!!!

What's the missing angle

Travka [436]

The missing angle is 27° because a triangle equals 180° and 180-119=61 and 61-34= 27.

A student raises her grade average from a 75 to a 90. What was the percent of increase

son4ous [18]

This can be solved algebraically. Before we start, as context, to find a percentage you multiply by the percentage/100.

$75*x=90 \\ x= \frac{90}{75} \\ \\ \boxed{x=1.2}$

This tells us that 90 is 120% of 75. However, your question wants us to find the <em>increase</em>, therefore we don't need that 100.
Therefore, the increase is 20%.
