Answer:

3x^2 + 17x + 10

Step-by-step explanation:

(x+5)(3x+2)

Using FOIL

(x)(3x) + (x)(2) + (5)(3x) + (5)(2)

= 3x^2 + 2x + 15x + 10

Combine like terms

= 3x^2 + 17x + 10

(a) A photography student borrows RM2 500 to buy a camera. The bank loans this money at a rate of 9 % capitalized monthly. What
Monica [59]

Answer:

The student will have to reimburse 2,991.03 two years later.

Step-by-step explanation:

This is a compound interest problem:

The compound interest formula is given by:

A = P(1 + \frac{r}{n})^{nt}

In which A is the amount of money, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit t and t is the time the money is invested or borrowed for.

In this problem, we have that:

A is the amount the student will have to reimburse two years later.

P is his loan. so P = 2,500

The bank loans this money at a rate of 9 % capitalized monthly. This means that r = 0.09 and n = 12, since the money is compounded monthly, this means, 12 times in a year.

He will have to reimburse two years later, so t = 2

A = P(1 + \frac{r}{n})^{nt}

A = 2,500(1 + \frac{0.09}{12})^{24}

A = 2,991.03

The student will have to reimburse 2,991.03 two years later.

On a certain day, the exchange rate was 60 U.S. dollars for 50 euro. How many U.S. dollars were 70 euro worth that day? Show tha
kvasek [131]
The exchange rate is 60:50 (us:euro)

if you have 70 euros, then x:70

60(x) : 70(50)

60x /60 : 3500/60

x = 58.33

seventy euro dollars = $ 58.33 on that particular day


hope this helps

Rico wants to find the distance between the points (-2,-3) and (2,-5) his work is shown.|-3| + |-5| = 3+5 = 8the distance is 8 u
tino4ka555 [31]

Answer:

Riko is wrong

Step-by-step explanation:

To find the distance of two point, we use the following formula:

A (x1, y1)

B (x1, y2)

AB = \sqrt{(x2-x1)^{2} + (y2-y1)^{2}  }

In this situation, we have:

A (-2,-3)

B  (2,-5)

So the distance is: \sqrt{(2 - (-2))^{2} + (-5 - (-3))^{2}  } = \sqrt{4^{2} + 8^{2} } = \sqrt{80} = 4\sqrt{5}

Hope it will find you well.
