Answer:

£1.22

Step-by-step explanation:

Total cost: 5.95+1.62+0.25+2(0.48)=8.78

Change: 10-8.78=1.22

How do you solve this pls

solong [7]

Step-by-step explanation:

The equation of a exponential function is

$a \times (b) {}^{x}$

where a is the y value of the y intercept, b is the constant rate of change.

Here the y intercept is (0,4), the y value of the y intercept is 4.

So a=4

The graph passes through point (1,2) so

$h(x) = 4 \times b {}^{x}$

Plug in 1 for x, 2 for h(x)

$2 = 4 \times {b}^{1}$

Anything to the first power is itself so

$2 = 4 \times b$

Isolate b.

$\frac{1}{2} = b$

So our function is

$4 \times ( \frac{1}{2} ) {}^{x}$

Find the exact length of the curve. x = 1 + 6t2, y = 4 + 4t3, 0 ≤ t ≤ 3

vovangra [49]

$x=1+6t^2\implies\dfrac{\mathrm dx}{\mathrm dt}=12t$

$y=4+4t^3\implies\dfrac{\mathrm dy}{\mathrm dt}=12t^2$

The length of the curve $C$ is given by

$\displaystyle\int_C\mathrm ds=\int_0^3\sqrt{\left(\frac{\mathrm dx}{\mathrm dt}\right)^2+\left(\dfrac{\mathrm dy}{\mathrm dt}\right)^2}\,\mathrm dt$

$=\displaystyle\int_0^3\sqrt{144t^2+144t^4}\,\mathrm dt$

$=\displaystyle12\int_0^3t\sqrt{1+t^2}\,\mathrm dt$

$=\displaystyle6\int_0^3 2t\sqrt{1+t^2}\,\mathrm dt$

$=\displaystyle6\int_0^3\sqrt{1+t^2}\,\mathrm d(1+t^2)$

$=6\cdot\dfrac23(1+t^2)^{3/2}\bigg|_0^3$

$=4(10^{3/2}-1)$

$=40\sqrt{10}-4$
