Choose the correct equation for an arithmetic<br> sequence in which t(4) = 8 and t(10) = 32<br> -
nadya68 [22]

Answer:

The equation is t(n) = -4 + 4(n-1)

Step-by-step explanation:

Arithmetic sequence:

In an arithmetic sequence, the difference between consecutive terms, called common difference, is always the same.

The general equation for an arithmetic sequence is:

t(n) = t(1) + d(n-1)

Taking the mth term as reference, the equation can be written as:

t(n) = t(m) + d(n-m)

t(4) = 8 and t(10) = 32

The common difference can be found:

t(n) = t(m) + d(n-m)

t(10) = t(4) + d(10-4)

6d = 24

d = \frac{24}{6} = 4

So

t(n) = t(1) + 4(n-1)

Finding the first term:

t(4) = t(1) + 4(n-1)

So

t(1) = t(4) - 12 = 8 - 12 = -4

So

The equation is t(n) = -4 + 4(n-1)

to test an​ individual's use of a certain​ mineral, a researcher injects a small amount of a radioactive form of that mineral in
LUCKY_DIMON [66]

Using derivatives, the rate of change of the mineral level with respect to time for 4 days is -0.012 mg/cm².

<h3>What is the missing information?</h3>

The function for the amount is missing, and is given by:

C(t) = \frac{1}{2}(6t + 1)^{-\frac{1}{2}}

The problems asks for the rate of change of the mineral level with respect to time for 4 days.

<h3>What is the rate of change after 4 days?</h3>

The rate of change after 4 days is given by:

C'(4).

Applying the chain rule, the derivative of C(t) is given as follows:

C^{\prime}(t) = \frac{1}{2}(6t+1)^\prime \times -\frac{1}{2} \times (6t+1)^{-\frac{3}{2}}

C^{\prime}(t) = -\frac{3}{2}(6t+1)^{-\frac{3}{2}}

When t = 4, we have that:

C^{\prime}(4) = -\frac{3}{2}(6(4)+1)^{-\frac{3}{2}}

C^{\prime}(4) = -\frac{3}{2}(25)^{-\frac{3}{2}}

Applying properties of exponents, we have that:

(25)^{-\frac{3}{2}} = \left(\frac{1}{25}\right)^{\frac{3}{2}} = \frac{1}{\sqrt{25^3}} = \frac{1}{25\sqrt{25}} = \frac{1}{125}

Hence:

C^{\prime}(4) = -\frac{3}{2} \times \frac{1}{125}

C'(4) = -0.012.

The rate of change of the mineral level with respect to time for 4 days is -0.012 mg/cm².

Sarah bought a TV at a 15% discount. Later she found that there should have been a 20% discount, so the store gave her $17 back.
ira [324]

Answer:

Step-by-step explanation:

The store gave her back the difference (20%-15%= 5%)

5%= the $17 returned

100/5= 20

20*17= $340 which was the original price of the TV before discounts
