Space shuttle Max is one of the extreme rides in enchanted kingdom. The first of its kind in the country, this roller coaster ri

de inverts its riders six times. If during one of its operations, a 53 kg boy experiences a net force of 1800N at the bottom of its rollercoaster loop, how fast would he be accelerating at this location?

Answer:

$Acceleration = 33.96ms^{-2}$ <em />

<em />

Step-by-step explanation:

Given

$Mass = 53kg$

$Force = 1800N$

Required

Determine the acceleration

The relationship between force, mass and acceleration is:

$Force = Mass * Acceleration$

Substitute values for Force and Mass

$1800 = 53 * Acceleration$

Solve for Acceleration

$Acceleration = 1800/53$

$Acceleration = 33.9622641509$

$Acceleration = 33.96ms^{-2}$ <em>---- Approximated</em>

larisa [96]

Answer: Total cost is $1.75

Explanation:

Since we have given that

Number of postcards bought by Doug's family= 7

Cost of each postcard including tax = $0.25

Total cost is given by

$7\times 0.25=\$1.75$

Now, we want to show this in number line :

On the number line put all the number with a difference of 0.25 and run the number line seven times and we get the answer.

Each step is of length 0.25 and there are 7 jumps to reach required answer.

So, after 7 jumps we reach at 1.75 which is the required answer.

Hence total cost is $1.75

JulsSmile [24]

Answer:

$\$57.88$

Step-by-step explanation:

we know that

The compound interest formula is equal to

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

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=3\ years\\ P=\$50\\ r=5\%=5/100=0.05\\n=1$

substitute in the formula above

$A=50(1+\frac{0.05}{1})^{1*3}$

$A=50(1.05)^{3}$

$A=\$57.88$

Find the value of questions

Zolol [24]

Answer:

The simplified expression is:

$\frac{3^9y}{2\times \:81}=\frac{243y}{2}$

Step-by-step explanation:

Given the expression

$\frac{3^9\times \:y}{2\times 81}$

solving the expression

$\frac{3^9\times \:y}{2\times 81}=\frac{3^9y}{162}$

$=\frac{3^9y}{3^4\times \:2}$ ∵ $162=3^4\times \:2$

$=\frac{3^5y}{2}$ ∵ $\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=x^{a-b}$

$=\frac{243y}{2}$ ∵ $3^5=243$

Therefore, the simplified expression is:

$\frac{3^9y}{2\times \:81}=\frac{243y}{2}$
