In the circle, CP=x and PD=y. If xy=28 and AP=2, then what is PB?

1 answer:

5 0

We know that
<span>When two chords intersect each other inside a circle, the products of their segments are equal
</span>
so
CP*PD=AP*PB
x*y=2*PB-----------> 28=2*PB----------> PB=14

the answer is
PB=14

Find the volume of the triangular pyramid to the nearest whole number (number only in your answer) Please help....

sertanlavr [38]

Answer:

Volume of pyramid = 317 units³

Step-by-step explanation:

Volume do triangular pyramid = ⅓ × Base Area × height of pyramid

Base area = ½*bh = ½*8*14 = 56 units²

Height of pyramid = 17

Volume of pyramid = ⅓ × 56 × 17

Volume of pyramid = 317 units³ (to nearest whole number)

A plane takes off and flies at an angle of 11° with the ground. When it reaches an elevation of 500 ft, what is the distance flo

drek231 [11]

Answer:

It had flown 2620 ft along the diagonal.

Step-by-step explanation:

When the plane is taking off it forms we can form a triangle with it's height, horizontal distance and diagonal distance, which can be seen in the attached drawing. We can use the sine relation on the right triangle to determine "x", as shown below:

sin(11°) = 500/x

x*sin(11) = 500

x = 500/[sin(11)] = 2620 ft

It had flown 2620 ft along the diagonal.
