Question 9 (1 point)

vitfil [10]

Answer:

Option 3: 200L + 100B > 5,000

Step-by-step explanation:

Each laptop costs 200 dollars, so this could be represented as 200L. Each bike costs 100 dollars, so this could be represented as 100B.

Jonathan wants his total of laptops and bikes to be more that 5,000, so we have to add 200L and 100B. When added, it should be more than 5,000 dollars.

200L + 100B > 5,000

A rare coin appreciates at a rate of 5.2% a year. If the initial value of the coin is $500, after how many years will its

Kisachek [45]

Answer: 36 years

Step-by-step explanation:

Exponential equation to represent growth:-

$y=A(1+r)^t$ , where A is the initial value , r is the rate of growth and t is the time period.

Given : A rare coin appreciates at a rate of 5.2% a year. If the initial value of the coin is $500.

i.e. Put A= 500 and r= 0.052 in the above formula.

The amount after t years:

$y=500(1.052)^t$

Inequality for value cross $3,000 mark:

$3000$

Divide both sides by 500

$6$

Taking log on both sides , we get

$\log6\dfrac{0.778151250384}{0.0220157398177}=35.345223773\\\\t\approx36$

Hence, it will take approx 36 years to cross the $3,000 mark.

ANSWER

C. 210

EXPLANATION

The given binomial expression is

$(x+y)^{10}$

Comparing to the general binomial expression,

$(a+b)^{n}$

we have

$n = 10$

Since we want to find the coefficient of

${x}^{6} {y}^{4}$

$r = 4$

Using the binomial theorem, the coefficient is

$nC_r = 10C_4 = 210$

The correct choice is C.
