5 0

Answer:

Option 4.) month 4

Step-by-step explanation:

we have

$f(x)=3^{x}$ ----> equation A

$g(x)=7x+6$ ----> equation B

Solve the system by graphing

Remember that the solution is the intersection point both graphs

The solution is the point (3,27)

That means -----> For x=3 months, the populations in both functions are the same (the bacteria populations is 27)

therefore

For x> 3 months the f(x) population is greater then the g(x) population

Mr Satyal borrowed Rs 50000 and after ane year she returned the loan by paying 60000. What is the intrest paid and what is the r

Hatshy [7]

The interest paid is Rs 10000

The rate of interest is 20%

Step-by-step explanation:

Step 1 :

Amount borrowed by Mr. Satyal = Rs 50000

Amount repaid = Rs 60000

Interest is charged on the principal amount and the amount repaid will be the sum of the interest paid plus the principal amount

Hence the interest paid is 60000 - 50000 = Rs 10000

Step 2:

The rate of interest is calculated as follows :

Divide the interest calculated by the principal amount and is expressed as percentage.

Hence the interest rate = $\frac{10000}{50000}$ × 100 = 20%

Step 3 :

The interest paid is Rs 10000

The interest rate is 20%

3.4=21 2.5=7. 4.4=؟

Licemer1 [7]

Answer:

Step-by-step explanation:

From the given values

The possible logic could be

if x.y is given

then it is equal to $=\frac{(x+y)\times x}{y-3}$

For 1st example

3.4 $=\frac{(3+4) \times 3}{4-3} =\frac{21}{1} =21$

For 2nd example

2.5 $=\frac{(2+5) \times 2}{5-3} =\frac{7 \times 2}{2} =7$

⇒4.4 $=\frac{(4+4)\times 4}{4-3} =32$

Please help! what is the polar equation r = -5 theta in parametric form? thank you!

Rudiy27

Use these equations when converting polar equations to parametric equations:

$x=r\cos\theta$

$y=r\sin\theta$

We know that $r=5\theta$ , so substitute that into both equations for x and y.

$x=5\theta\cos\theta$

$y=5\theta\sin\theta$

Now, replace $\theta$ with any variable that you want to represent the parametric equations in. I'll use the standard variable, $t$

$x=5t\cos t$

$y=5t\sin t$

Thus, $r=5\theta$ represented in parametric form is:

$(x,y)=(5t\cos t, 5t \sin t)$

Let me know if you need any clarifications, thanks!
