For r=2+3sintheta find dy/dx and the slope of the tangent line to the curve

1 answer:

8 0

F(x)=2+3sin(theta)
f'(x)=3cos(theta)

To find the slope you need the value of theta. The general formula is:

y-f(xo)=f'(xo)-(x-xo)

Jane and sali cycled along the same 63 km route.

Alina [70]

Answer:

Sali's speed was 18.75 km/h.

Step-by-step explanation:

Jane took 3.5 hours to cycle the 63 km.

As, $Speed= \frac{Distance}{Time}$ , so the speed of Jane will be: $\frac{63}{3.5} km/h = 18 km/h$

Suppose, the speed of Sali is $x$ km/h

Sali caught up with Jane when they had both cycled 30 km.

So, the time required for Jane to cycle 30 km $= \frac{30}{18}=\frac{5}{3} hours$ and the time required for Sali to cycle 30 km $=\frac{30}{x} hours$

Given that, Sali started to cycle 4 minutes or $(\frac{4}{60}) or (\frac{1}{15}) hours$ after Jane started to cycle. So, the equation will be.......

$\frac{5}{3}-\frac{30}{x}= \frac{1}{15}\\ \\ \frac{30}{x}= \frac{5}{3}-\frac{1}{15}\\ \\ \frac{30}{x}= \frac{24}{15}\\ \\ 24x=450\\ \\ x= \frac{450}{24}= 18.75$

Thus, the speed of Sali was 18.75 km/h.

Which are the solutions of x2 = –13x – 4?

kobusy [5.1K]

x2 = -13x - 4=

2x = -13x - 4=

2x+13x=-13x-4+13x

15x=-4

x=4/15

i hope this is correct
