Answer:

f(x+2)=3x+10

Explanation:

f(x+2) means replace all the xs with (x+2)

f(x)=3x+4

f(x+2)=3(x+2)+4

Now simplify

f(x+2)=3x+6+4

f(x+2)=3x+10

Ashish deposite rs 1000 every month is a recurring deposit account for period of 12 months. If the bank pays interest at a certa

rusak2 [61]

Solution :

Given :

Principal amount, P = Rs. 1000

Time period = 12 months

The maturity value = Rs. 12,715

We know that,

$SI = \frac{PTR}{100}$

$SI = 1000 \times \frac{n(n+1)}{2 \times 12} \times \frac{R}{100}$

$SI = 1000 \times \frac{12(12+1)}{2 \times 12} \times \frac{R}{100}$

SI = 65 R

So we know,

maturity value = principal amount + SI

12715 = 1000 + 65 R

65 R = 12715 - 1000

65 R = 11715

R = 18%

So the rate is 18%

A particle is moving along the parabola x^2=4(y+6). As the particle passes through the point (8,10), the rate of change of its y

Fofino [41]

You'll need to use differentiation (specifically, implicit differentiation) here.

If x^2 = 4(y+6), differentiating both sides with respect to time t produces the following:

2x (dx/dt) = 4([dy/dt]) (note that (d/dt) 6 = 0)

We need to solve for (dx/dt). Substitute 8 for x (y does not appear in this latest equation, so we do nothing with y=10). Substitute the given 5 units/sec for dy/dt:

2(8)(dx/dt) = 4(5)(units/sec)

Solving for dx/dt, dx/dt = [20 units/sec]/16, or 5/4 units/sec, or 1.25 units/sec.

Which is a stretch of an exponential decay function? f(x) = one-fifth (one-fifth) superscript x f(x) = one-fifth(5)x f(x) = 5one

vitfil [10]

The exponential function that represents a stretch of a decay function is given as follows:

$f(x) = \frac{5}{4}\left(\frac{4}{5}\right)^x$

<h3>What is an exponential function?</h3>

An exponential function is modeled by:

$y = ab^x$ .

In which:

a is the initial value.

b is the rate of change.

It represents a stretch if a > 1, and a decay function if b < 1. Researching the problem on the internet, the correct option is given as follows:

$f(x) = \frac{5}{4}\left(\frac{4}{5}\right)^x$
