PLEASE HELP WITH THIS ONE AS WELL! I’m struggling with Transcendental Functions!

$h(x)=20e^{kx}$

a. If $h(1)=20$ , then $20=20e^k\implies e^k=1\implies k=0$ .

b. If $h(1)=40$ , then $40=20e^k\implies e^k=2\implies k=\ln2$ , so that $2k+1=2\ln2+1$ .

c. If $h(1)=10$ , then $10=20e^k\implies e^k=\dfrac12\implies k=-\ln2$ , so that $k-3=-\ln2-3$ .

A triangle has an area of 50cm its base is four times the height what is the height?

babunello [35]

So area=1/2 base times height
50=1/2 base times height
multiply both sides by 2
100=base times height
base=4height
100=4height times height
100=4height^2
divide 4
25=height^2
squarer root
5=height

subisute
base=4(5)
base=20

height=5

D)) The ratio of the monthly income and expenditure of Sunayana is 5 : 3. If she

Gnom [1K]

Answer:

Sunayana's income is ₹25000 and expenditures are ₹15000.

Step-by-step explanation:

Let i denote the monthly income and e denote the expenditures.

We know that the ratio of the monthly income to expenditure is 5:3. So, we can write the following proportion:

$\frac{i}{e}=\frac{5}{3}$

Let's multiply both sides by e. This yields:

$i=\frac{5}{3}e$

We know that when the income is increased by 5000 and the expenditures are decreased by 3000, the new ratio is 5:2. So, we can write the following proportion:

$\frac{i+5000}{e-3000}=\frac{5}{2}$
