<u>Answer</u>

<u>Right Scalene Triangle</u>

Side a (X) = 14.91038 (To the nearest hundreth: 14.91)

Side b = 7

Side c = 13.16509

Angle ∠A = 90° = 1.5708 rad = π/2

Angle ∠B = 28° = 0.48869 rad

Angle ∠C = 62° = 1.0821 rad

Calculations:

alculated based on 2 given angles and 1 given side.

∠C = 180° - A - B = 1.0821 rad = 62°

a = b·sin(A)/sin(B) = 14.91038

c = b·sin(C)/sin(B) = 13.16509

Area =  

ab·sin(C)

2

 = 46.0778

Perimeter p = a + b + c = 35.07547

Semiperimeter s =  

a + b +c

2

 = 17.53773

Height ha =  

2×Area

a

 = 6.18063

Height hb =  

2×Area

b

 = 13.16509

Height hc =  

2×Area

c

 = 7

Median ma = √(a/2)2 + c2 - ac·cos(B) = 7.45519

Median mb = √(b/2)2 + a2 - ab·cos(C) = 13.62239

Median mc = √(c/2)2 + b2 - bc·cos(A) = 9.60884

Inradius r =  

Area

s

 = 2.62735

Circumradius R =  

a

2sin(A)

 = 7.45519

Solve for x in the equation:log6-2logx=1.4​
Annette [7]

9514 1404 393

Answer:

  x = (√6)/10^0.7 ≈ 0.488737

Step-by-step explanation:

It can work reasonably well to take antilogs first.

  \log(6)-2\log(x)=1.4\\\\\dfrac{6}{x^2}=10^{1.4}\\\\\dfrac{6}{10^{1.4}}=x^2\\\\x=\dfrac{\sqrt{6}}{10^{0.7}}\approx0.488737

The 9th and the 12th term of an arithmetic progression are 50 and 65 respectively. find the common difference
Rzqust [24]

The first term of the arithmetic progression exists at 10 and the common difference is 2.

<h3>How to estimate the common difference of an arithmetic progression?</h3>

let the nth term be named x, and the value of the term y, then there exists a function y = ax + b this formula exists also utilized for straight lines.

We just require a and b. we already got two data points. we can just plug the known x/y pairs into the formula

The 9th and the 12th term of an arithmetic progression exist at 50 and 65 respectively.

9th term = 50

a + 8d = 50 ...............(1)

12th term = 65

a + 11d = 65 ...............(2)

subtract them, (2) - (1), we get

3d = 15

d = 5

If a + 8d = 50 then substitute the value of d = 5, we get

a + 8 * 5 = 50

a + 40 = 50

a = 50 - 40

a = 10.

Therefore, the first term is 10 and the common difference is 2.
