Answer:

(5,3)

Step-by-step explanation:

Look for the coordinates of the point of intersection where the 2 graphs cross. This gives the solution.

In this case, they cross at (5,3) and they intersect at only one location (i.e there is only 1 solution)

elixir [45]

Given:

Principal value = $1500

Rate of interest = 7% per annum compounded daily

Time = 2 years.

To find:

The amount after 2 years.

Solution:

Formula for amount:

$A=P\left(1+\dfrac{r}{n}\right)^{nt}$

Where, P is principal, r is the rate of interest in decimals, n is the number of time interest compounded in an year and t is the number of years.

We know that 1 year is equal to 365 days and the interest compounded daily. So, n=365.

Substituting $P=1500,\ r=0.07,\ n=365,\ t=2$ in the above formula, we get

$A=1500\left(1+\dfrac{0.07}{365}\right)^{365(2)}$

$A=1500\left(\dfrac{365+0.07}{365}\right)^{730}$

$A=1500\left(\dfrac{365.07}{365}\right)^{730}$

Using calculator, we get

$A\approx 1725.39$

The amount after two years is $1,725.39. Therefore, the correct option is (c).

Find the product of the expression:<br> (5p^3) (-1m^8p^2)

Rainbow [258]

Answer:

We conclude that:

$\left(5p^3\right)\:\left(-1m^8p^2\right)=-5p^5m^8$

Step-by-step explanation:

Given the expression

$\left(5p^3\right)\:\left(-1m^8p^2\right)$

Apply the rule:

$a\left(-b\right)=-ab$

so the expression becomes

$\left(5p^3\right)\left(-1\cdot \:m^8p^2\right)=-5p^3\cdot \:1\cdot \:m^8p^2$

Apply the rule:

$a^b\cdot \:a^c=a^{b+c}$

so the expression becomes

$=-5p^{3+2}\cdot \:1\cdot \:m^8$ ∵ $p^3p^2=p^{3+2}$

$=-5p^5\cdot \:1\cdot \:m^8$

$=-5p^5m^8$

Therefore, we conclude that:

$\left(5p^3\right)\:\left(-1m^8p^2\right)=-5p^5m^8$

(1) Cos AcosecA=cot A

Mashutka [201]

Answer:

The Basic Identities are :

$cosec(A) = \frac{1}{ \sin(A) }$

$\tan(A) = \frac{ \sin(A) }{ \cos(A) }$

$\cot(A) = \frac{1}{ \tan(A) } = \frac{ \cos(A) }{ \sin(A) }$

So for this question :

$\cos(A)cosec(A) = \cot(A)$

$l.s.h = \cos(A) \times \frac{1}{ \sin(A) }$

$l.s.h = \frac{ \cos(A) }{ \sin(A) }$

$l.sh = \cot(A) \: (proven)$
