Answer:

10

Step-by-step explanation:

find out f(2)

f(2)= (3×2×2) - 4= 8

then g(8) = 16 - 6= 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.

geometry- please help. like seriously if u know how to do it, it would help me so much and i’d mark u brainliest
Paraphin [41]

Answer:

the arc length is 555.17 cm

Step-by-step explanation:

The equation to solve for the arc length is: s = rΘ, where r represents the radios and the Θ represents radians. In order to solve this you need to convert degrees into radians with the formula: radians = degrees ·

You want to find the distance the golf club travels when the golfer swings the club.

First you need to subtract 25° from 360°

360° - 25° = 335°

now you need to convert 335° into radians

radians = degrees ·

radians = 335° · you multiply 335° by

radians = 335/180 then you simplify

radians = 67/36

335° = 67\pi/36

Now we plug everything we know into the equation s = rΘ

s = rΘ

s = 95 (67\pi/36)        first multiply 67 by 3.14

s = 95 (210.38/36)    divide 210.38 by 36

s = 95 (5.843888889)   and multiply 95 by 5.843888889

s = 555.1694444  *remember to simplify to the nearest hundredth

s = 555.17 cm

hope this helps! if u have any questions, let me know!

Take your time! :) Not important, but I would like to know, I'm writing flashcards so I can remember when I start back in school
Sav [38]

Answer:

The LCM of two numbers is the least common multiple. You want to find the least possible number that is divisible by the two numbers. So, you can list the factors of the two numbers. If there are factors that are repeated, put the repeated factors to the side. With the remaining factors, multiply the factors by each other and the repeated factors.

For example, let's try to find the least common multiple between 10 and 15.

Factors of 10: 2 * 5

Factors of 15: 3 * 5

The repeated factor is 5.

2 and 3 are left over. 2 * 3 = 6. 6 * 5 = 30. So, that is the least common multiple.

The GCF of two numbers is the greatest common factor. You want to find the greatest factor that is included in both numbers. So, again, you can list the factors of the two numbers and find the greatest factor that is repeated between the two numbers.

For example, let's try to find the greatest common factor between 30 and 45.

Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30

Factors of 45: 1, 3, 5, 9, 15, 45

Between the two numbers, shared factors are 1, 3, 5, and 15. So, the greatest common factor is 15.

Hope this helps!
