Answer:

-1/2=b <--- y int. y=-5/2x-1/2 slope= -5/2

Step-by-step explanation:

So the slope is -5/2x because its given

the original equation: y=-5/2x-1/2

if x=0,

y=-1/2 (0,-1/2)

enter this into the y=-5/2x+b

-1/2=b <--- y int.

so the new equation is

y=-5/2x-1/2

Answer:

\int\limits^{\pi/2} _0 (1+4cos^{2} (2x)dx

Step-by-step explanation:

Arc length is calculated by dividing the arcs in to small segments ds

By pythagoren theorem

$ds^2=dx^2+dy^2$

then integrate ds to get arc length.

We are given a function as

y = sin 2x in the interval [0, pi/2]

To find arc length in the interval

Arc length $s =\int\limits^{\pi/2} _0 {1+y'^2} \, dx \\=\int\limits^{\pi/2} _0 (1+4cos^{2} (2x) )dx$

Hence arc length would be

B) $\int\limits^{\pi/2} _0 (1+4cos^{2} (2x)dx$

Kesha deposits $1000 into a savings account earning 6% interest each year. She makes no further deposits to the account. What is

kodGreya [7K]

Answer:

$1000*1.06^{5} = 1 338.2255776 $$ $

~ 1 338 $

Step-by-step explanation:

The 6% interest earning: 1 + 6 / 100 => 1.06

Since she doesn't make any transactions on the account, at the end of 5 years she'll have: $1000*1.06^{5} = 1 338.2255776 $$
