damaskus [11]

Given:

There are given that the two paths and one path are 2 miles from the road.

Explanation:

Suppose the distance from the playground to the road is x.

To find the value x, we need to use the cos function;

So,

From the cos function in the given right angle triangle:

$cos50^{\circ}=\frac{x}{2}$

Then,

$\begin{gathered} cos50^{\operatorname{\circ}}=\frac{x}{2} \\ 0.64=\frac{x}{2} \end{gathered}$

Then,

$\begin{gathered} 0.64=\frac{x}{2} \\ x=0.64\times2 \\ x=1.28 \\ x=1.3mi \end{gathered}$

Final answer:

Hence, the correct option C.

A person borrowed Rs. 5550 from is at 4% compound interest Rs 500 was paid each year. what amount paid at the end of 5th year wi

nordsb [41]

Solution :

Money left after 1st year :

$M = 5550( 1 + \dfrac{4}{100}) - 500 = 5272$

Money left after 2nd year :

$M = 5272( 1 + \dfrac{4}{100}) - 500 = 4982.88$

Money left after 3rd year :

$M = 4982.88( 1 + \dfrac{4}{100}) - 500 = 4682.19$

Money left after 4rd year :

$M = 4682.19( 1 + \dfrac{4}{100}) - 500 = 4369.48$

Money left after 5rd year :

$4369.48(1+\dfrac{4}{100})-500 = 4044.26$

At the end of 5th year an amount of Rs 4044.26 will clear the debt.

Find the x and y intercepts of the graph of

skad [1K]

Answer:

x-intercept : 4

y-intercept : 22

Step-by-step explanation:

The equation is given as ;

11x + 2y = 44

write the equation in form of y= mx + c where c is the y-intercept and m is the gradient.

11x + 2y = 44

2y =-11x + 44 ----divide each term by 2 as;

y= -11/2 x + 44/2

y= -5.5 x + 22 ------equation of the graph

y-intercept is 22

x- intercept is the value of x when y=0

y= -5.5 x + 22

0 = -5.5 x + 22

5.5 x = 22

x = 22/ 5.5

x= 4

You can also plot a graph to view the relationship ;
