In ΔOPQ, o = 500 cm, p = 600 cm and q=380 cm. Find the measure of ∠P to the nearest 10th of a degree.

TEA [102]

Answer: 84.8°

Step-by-step explanation:

a²+b²+c²-2bc(cosA)

cosA = b² + c² - a² / 2bc

That is the formula we will be using.

Then, plug in our numbers.

cosP= 500² + 380² - 600² / 2(500)(380)

cosP= 34400/380000

cosP≈ 0.09052631

cos⁻¹(0.09052631) ≈ 84.81

∠P = 84.8°

ahrayia [7]

Answer:

$x^{2}-16x+64$

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

1. You have the following perfect square trinomial given in the problem:

$x^{2}-16+$

2. To fill the missing term, you must divide the coefficient -16 by 2 and then you must square it, as following:

Given the equation below, find the x and y−intercepts by completing the table.What is the problem with using these intercepts to

kvasek [131]

$-4x+2y=0$

In order to find the x-intercept we need to make y=0

$-4x+2(0)=0$

Then we isolate the x

$-4x=0$ $x=0$

x y Ordered Pair type of intercept

0 0 (0,0) x-intercept

Now for the y-intercept we need to make x=0

$-4(0)+2y=0$

we isolate the y

$2y=0$

$y=0$

0 0 (0,0) y-intercept

ANSWER

0 0 (0,0) x-intercept
