Victoria has some money from her birthday and the amount is modeled by the function h(x) = 200. She read about a bank that has s

djyliett [7]

Interest gained for a particular period equals to Money invested (kept) in Savings account for that period <em>multiplied by </em>Interest accrued on this money.

Therefore, Accrued interest i(x) = h(x) * s(x) = 200 * [ (1.05)x - 1 ],
where x is the number of years for which money is invested.

So, new function i(x) = (210)x - 200 .

Jennifer and Kamlee are walking to school. After 20 minutes, Jennifer has walked 4/5 miles. After 25 minutes, Kamlee has walked

Nimfa-mama [501]

Answer:

Jennifer's speed is 2.4 miles/hour

Kamlee's speed is 2 miles/hour

Step-by-step explanation:

To find their speed,

Speed can be determined from the formula below,

$Speed = \frac{Distance}{Time}$

Also, to determine the speed in miles per hour (miles/hour), we will convert the time spent by each of them to hour (NOTE: 60 minutes = 1 hour)

For Jennifer,

Distance = 4/5 miles

Time = 20 mins (Convert to hour)

∴Time = (20/60) hour = 1/3 hour

Hence,

$Speed = \frac{Distance}{Time}$

$Speed = \frac{4/5 miles}{1/3hour}$

$Speed = \frac{4}{5} \times \frac{3}{1}$

$Speed = \frac{12}{5}$

$Speed = 2.4 miles/hour$

Hence, Jennifer's speed is 2.4 miles/hour

For Kamlee,

Distance = 5/6 miles

Time = 25 minutes (Convert to hour)

Time = (25/60) hour = 5/12 hour

Hence,

$Speed = \frac{Distance}{Time}$

$Speed = \frac{5/6miles}{5/12 hour}$

$Speed = \frac{5}{6} \times \frac{12}{5}$

$Speed = 2 miles/hour$

Hence, Kamlee's speed is 2 miles/hour

Suppose that x and y are positive integers such that x^2 * y^3=46656. What is the sum of all possible values of x?

Nostrana [21]

Answer:

252

Step-by-step explanation:

x² * y³=46656

<u>Prime factors of 46656:</u>

46656 = 2⁶3⁶

<u>Possible values of x:</u>

(2*3)³= 216
3³ = 27
2³ = 8
1

<u>Sum of them:</u>

216 + 27 + 8 + 1 = 252

M-N is $M-N=2x^2+11x-9$

Option B is correct.

Step-by-step explanation:

If $M=5x^2+7x-4$ and $N=3x^2-4x+5$ then find M-N

We need to subtract N from M

We will combine like terms (terms having same variable and exponent) and then solve them:

$M=5x^2+7x-4$

$N=3x^2-4x+5$

$M-N=5x^2+7x-4-(3x^2-4x+5)\\M-N=5x^2+7x-4-3x^2+4x-5\\Combining\,\,like\,\,terms:\\M-N=5x^2-3x^2+7x+4x-4-5\\M-N=2x^2+11x-9$

So, M-N is $M-N=2x^2+11x-9$

Option B is correct.
