t(n) = 2 {n}^{2} + 2n

_________________________________

t(1) = 2 ({1})^{2} + 2(1)

t(1) = 2 \times 1 + 2 \times 1

t(1) = 2 + 2 = 4

##############################

t(2) = 2 ({2})^{2} + 2(2)

t(2) = 2 \times 4 + 2 \times 2

t(2) = 8 + 4 = 12

##############################

t(3) = 2 ({3})^{2} + 2(3)

t(3) = 2 \times 9 + 2 \times 3

t(3) = 18 + 6 = 24

##############################

t(4) = 2 ({4})^{2} + 2(4)

t(4) = 2 \times 16 + 2 \times 4

t(4) = 32 + 8 = 40

##############################

t(5) = 2 ({5})^{2} + 2(5)

t(5) = 2 \times 25 + 2 \times 5

t(5) = 50 + 10

t(5) = 60

If two parents, one with brown eyes (a dominant trait) and the other with blue eyes (the recessive trait) produce one twin boy w
Lera25 [3.4K]

Answer:

50 percent

Step-by-step explanation:

It is given that one of the parent with a dominant trait have brown eyes and the other parent with a recessive trait has blue eyes. They produce a twin boy with eyes that is blue in color. So the probability of the fraternal twin to transmit his allele of blue eye to his or her offspring is 50 percent.

And also the probability of the offspring to pass the allele on to his or her offspring is 50 %.

The product rule is used : 0.5 x 0.5 = 0.25 or 25%.

Find the interest rate if £6400 has a final value of £8334 in 3 years. Give your answer to 1 d.p​
Mila [183]

Answer:

Step-by-step explanation:

6400(1+i)³=8334

(1+i)³=1.3021875

∛(1+i)³=∛(1.3021875)

1+i= 1.092

i= .092

I guess if you were to round to 1 decimal point it'd be .1

What is the intial value and rate of change in this graph. please explain step by step!!!!!
WARRIOR [948]

The initial value of the graph is where x = 0. Thus, in this case, the initial value is 12.


The rate of change of the graph is essentially the slope of the graph. In this case, we can use the slope formula:

\dfrac{y_2 - y_1}{x_2 - x_1}

  • (x_1, y_1) and (x_2, y_2) are points on the graph

Let's use two points from the chart to find the slope:

m = \dfrac{30 - 21}{2 - 1} = 9


In this case, the rate of change of the graph is 9.
