What is the measure of AngleP to the nearest whole degree? 35° 52° 57° 72°.

Answers

You can use the law of cosine to find the measure of angle P.

The measure of angle P is given by

Option C : 57°

What is law of cosine?

Let there is triangle ABC such that |AB| = a units, |AC| = b units, and |BC| = c units and the internal angle A is of θ degrees, then we have:

[tex]c^2 = a^2 + b^2 - 2ab\cos(\theta)}[/tex]

(c is opposite side to angle A)

Using the law of sines to find the measure of angle P in the given context

Refer to the attached figure below.

Using the cosine law, we get

|PQ| = a = 17 units, |QR| =length of  opposite side to P = c = 15 units, |PQ| = b = 14 units.

Thus, let angle QPR be of θ degrees, then

[tex]cos(\theta) =\dfrac{a^2 + b^2 - c^2}{2ab} = 0.546\\\\\theta = arccos(0.546) = 56.9^\circ, -56.9^\circ[/tex]

triangle's angles are measured positive, thus, measure of angle P came out as 56.9 degrees or approx 57°

Thus,

The measure of angle P is given by

Option C : 57°

What should be added to –7mn+2m2+3n2

to obtain 5m2+2mn-9n2​

Answers

The polynomial to be added to –7mn + 2m² + 3n² to obtain 5m² + 2mn - 9n² is: 3m² - 11n² + 9mn.

Addition of Polynomials

Like terms should be combined together when adding polynomials.

Let x represent the polynomial expression that would be added to –7mn + 2m² + 3n² to obtain 5m² + 2mn - 9n².

Therefore:

–7mn + 2m² + 3n² + x = 5m² + 2mn - 9n².

x = 5m² + 2mn - 9n² - (-7mn + 2m² + 3n²)

x = 5m² + 2mn - 9n² + 7mn - 2m² - 3n²

Combine like terms together.

x = 3m² - 11n² + 9mn

Therefore, the polynomial to be added to –7mn + 2m² + 3n² to obtain 5m² + 2mn - 9n² is: 3m² - 11n² + 9mn.

Explanation:

Here are the first four terms of an arithmetic sequence. 3,10,17,24. Is 150 a term in this sequence?

Answers

Answer:

1046

Step-by-step explanation:

formula for arithmetic sequence is:

aₙ = a₁ + (n-1)d

a₁ = first value in sequence

n = term value

d = common difference

a(150) = 3 + (150-1)7

= 3+1043

= 1046

150 is a term in this sequence, its 22nd of the sequence

What is arithmetic sequence?

An arithmetic sequence is sequence of integers with its adjacent terms differing with one common difference.

If the initial term of a sequence is 'a' and the common difference is of 'd', then we have the arithmetic sequence as:

a, a + d, a +  2d, ... , a + (n-1)d, ...

Its nth term is

T_n = a + (n-1)d

(for all positive integer values of n)

And thus, the common difference is

T_{n+1} - T_n

for all positive integer values of n

Given;

The arithmetic sequence; 3,10,17,24

D= 10-3=7, a=3

150=3+(n-1)7

150=3+7n-7

150=7n-4

150+4=7n

7n=154

n=154/7

n=22

Therefore, 150 is 22nd term of the sequence.

The average of six weights is 12 kilograms. Another weight of 5 kilograms is added to the scale. What is the average of the seven weights?

Answers

Answer:

Hi there! Your answer here is 11kg - the average of the seven weights is 11kg. To find the average of a group of numbers, you add all of the numbers (12, 12, 12, 12, 12, 12, 5), then divide by the count of those numbers (7).

12 + 12 + 12 + 12 + 12 + 12 + 5 (or 12*6 + 5) is equal to 77.

77 / 7 = 11.

So the average of the seven weights is 11kg.

well, we know it's centered at (-2 , 1) and it passes through (-4 , 1), if it passes through there, that means that the distance from the center to (-4 , 1) must be its radius.
