Answer:

67.5°

Step-by-step explanation:

From the diagram attached, it can be seen that <BAD = 90° (right angled). Also <BAD = <CAD + <BAC

From the question, we are told that the measurement of CAD is three times measurement of BAC, this means <CAD = 3<BAC

substituting this condition into the formula above:

<BAD = 3<BAC + <BAC

<BAD = 4<BAC

4<BAC = 90

<BAC = 90/4

<BAC = 22.5°

Next is to get <CAD:

<CAD = 3<BAC

<CAD = 3(22.5)

<CAD = 67.5°

Hence the measurement of <CAD is 67.5°

Which geometric series converges?
kvv77 [185]

Answer:

Option (1)

Step-by-step explanation:

In a geometric series,

\sum_{n=0}^{\infty}ar^n=a+ar^1+ar^2+....

Here r = \frac{a_n}{a_{n-1}}

For |r| < 1, series will converge.

For |r| > 1, series will diverge.

Option (1)

Given geometric series is,

\frac{1}{2}+\frac{1}{4}+ \frac{1}{8}+ \frac{1}{16}.......

Common ratio = \frac{\frac{1}{4}}{\frac{1}{2} }

                        = \frac{1}{2}

Since, \frac{1}{2}

Series will converge.

Option (2)

\frac{1}{2}+1+2+4+......

r = \frac{1}{\frac{1}{2}}=2

Since, 2 > 1,

Series will diverge.

Option (3)

\frac{1}{2}+ \frac{3}{2}+ \frac{9}{2}+ \frac{27}{2}+......

Common ratio 'r' = \frac{\frac{3}{2} }{\frac{1}{2} }=3

Since, 3 > 1,

Series will diverge.

Option (4)

\frac{1}{2}+3+18+108+.....

Common ratio 'r' = \frac{3}{\frac{1}{2}}=6

Since, 6 > 1

Series will diverge.

Therefore, Option (1) will be the correct option.

an object is launched at 25 m/s from a height of 80 m. the equation for the height (h) in terms of time (t) is given by h(t)=4.9
Aneli [31]

There must be minus sign with 4.9 .

h(t) = -4.9t^2+25t +80

The given equation is the equation of parabola , which is maximum at its vertex, and the formula of vertex is

t=-\frac{b}{2a}=-\frac{25}{2(-4.9)}  = 2.55 seconds

So the height is maximum at t=2.55 seconds and to find the maximum height , we need to plug 2.55 for t , that is

h(2.55)=-4.9(2.55)^2+25(2.55)+80 = Approx \ 112 \ m

So the maximum height is 112 m .
