Find the angle between and if ⋅=3√2‖‖⋅‖‖.

(Use symbolic notation and fractions where needed. Give your answer in terms of . )

answer :

∅ = π / 6

Step-by-step explanation:

V .W = $\frac{\sqrt{3} }{2} || V ||. ||W||$

Hence

∅ = cos^-1 ( $\frac{\frac{\sqrt{3} }{2} || V ||. ||W||}{||V||.||W||}$

∅ = cos^-1 ( $\frac{\sqrt{3} }{2}$ )

∴ ∅ = π / 6

Out of 460 students, 60% have pets. How many of the students have pets?

Margaret [11]

In order to find the number, we will need to set it up in an equation. In total, there are 460 students while 60% of them have pets. Lets set that up.
460(60%)
In order to correctly do this, we will need to transfer 60% into a decimal, which is .6. Now we will rewrite it.
460(.6)
This now can be represented by the number 276.Since we know that 276 is 60% of 460, The total number of students that have pets will be 276.

What is the length of line segment PQ? If you can please explain, thanks.

nydimaria [60]

Given:

Tangent segment MN = 6

External segment NQ = 4

Secant segment NP =x + 4

To find:

The length of line segment PQ.

Solution:

Property of tangent and secant segment:

If a secant and a tangent intersect outside a circle, then the product of the secant segment and external segment is equal to the product of the tangent segment.

$\Rightarrow NQ\times NP = MN^2$
