In the diagram, is the perpendicular bisector of and is also the angle bisector of . If m = x, which quantity is equal to sin ?

earnstyle [38]

Given that line PN is a perpendcular bisector of line AB, then angles APN and BPN are equal to 90 degrees each.

Also, given that line PN is an angle bisector to angle CPD and angle CPD measures x, then the measure of angle DPN is $\frac{1}{2} x$ .

Thus, the measure of angle DPB = angle BPN - angle DPN
$=90- \frac{1}{2} x$

Therefore,
$\sin DPB=\sin\left(90- \frac{1}{2} x\right) \\ \\ =\sin(90)\cos\left(\frac{1}{2} x\right)-\sin\left(\frac{1}{2} x\right)\cos(90) \\ \\ =\cos(\frac{1}{2} x)$

Simplify the square root of 5 times the cube root of 5.

mihalych1998 [28]

Answer:

Option 3 - five to the two thirds power

Step-by-step explanation:

Given : Expression 'the square root of 5 times the cube root of 5'.

To find : Simplify the expression ?

Solution :

Writing expression in numeric form,

The cube root of 5 means $\sqrt[3]{5}$

The square root of 5 times the cube root of 5 means $\sqrt{5\sqrt[3]{5}}$

Now, simplify the expression

$\sqrt{5\sqrt[3]{5}}=\sqrt{5\times (5)^{\frac{1}{3}}}$

$\sqrt{5\sqrt[3]{5}}=\sqrt{(5)^{1+\frac{1}{3}}}$

$\sqrt{5\sqrt[3]{5}}=\sqrt{(5)^{\frac{4}{3}}}$

$\sqrt{5\sqrt[3]{5}}=((5)^{\frac{4}{3}})^{\frac{1}{2}}$

$\sqrt{5\sqrt[3]{5}}=(5)^{\frac{4}{3}\times \frac{1}{2}}$

$\sqrt{5\sqrt[3]{5}}=(5)^{\frac{2}{3}}$

The expression is five to the two thirds power.

Therefore, Option 3 is correct.

Jennifer and Kamlee are walking to school. After 20 minutes, Jennifer has walked 4/5 miles. After 25 minutes, Kamlee has walked

Nimfa-mama [501]

Answer:

Jennifer's speed is 2.4 miles/hour

Kamlee's speed is 2 miles/hour

Step-by-step explanation:

To find their speed,

Speed can be determined from the formula below,

$Speed = \frac{Distance}{Time}$

Also, to determine the speed in miles per hour (miles/hour), we will convert the time spent by each of them to hour (NOTE: 60 minutes = 1 hour)

For Jennifer,

Distance = 4/5 miles

Time = 20 mins (Convert to hour)

∴Time = (20/60) hour = 1/3 hour

Hence,

$Speed = \frac{Distance}{Time}$

$Speed = \frac{4/5 miles}{1/3hour}$

$Speed = \frac{4}{5} \times \frac{3}{1}$

$Speed = \frac{12}{5}$

$Speed = 2.4 miles/hour$

Hence, Jennifer's speed is 2.4 miles/hour

For Kamlee,

Distance = 5/6 miles

Time = 25 minutes (Convert to hour)

Time = (25/60) hour = 5/12 hour

Hence,

$Speed = \frac{Distance}{Time}$

$Speed = \frac{5/6miles}{5/12 hour}$

$Speed = \frac{5}{6} \times \frac{12}{5}$

$Speed = 2 miles/hour$

Hence, Kamlee's speed is 2 miles/hour
