If the measure of angle DCF = 34 and the measure of angle DEF = 90, find the measure of angle CDE.

spayn [35]

Answer:

118

Step-by-step explanation:

Triangle CDE contains angles CDE, DCR and DER

Angles DCR=17 and DER=45 because in a kite, the diagonal on the line of symmetry bisects the angles and 34-2=17 90/2=45

The angles in a triangle add up to 180 and 180-17-45=118, meaning angle DER=118

A baseball is thrown into the air and follows a parabolic path given by the equation s = -16t 2 + v0t, where s is feet above gro

Alla [95]

Answer: 64 ft

Step-by-step explanation:

We are given the following equation that models the baseball's parabolic path:

$s=16t^{2}+V_{o}t$ (1)

Where:

$s$ is the ball maximum height

$t$ is the time

$V_{o}=64 ft/s$ is the initial height

With this information the equation is rewritten as:

$s=16t^{2}+(64)t$ (2)

Now, we have to find $t$ , and this will be posible with the following formula:

$V=V_{o}-gt$ (3)

Where:

$V=0 ft/s$ is the final velocity of the ball at the point where its height is the maximum

$g=32 ft/s^{2}$ is the acceleration due gravity

Isolating $t$ :

$t=\frac{V_{o}}{g}$ (4)

$t=\frac{64 ft/s}{32 ft/s^{2}}$ (5)

$t=2 s$ (6)

Substituting (6) in (2):

$s=16 ft/s^{2}(2 s)^{2}+(64 ft/s)(2 s)$ (7)

Finally:

$s=64 ft$
