Find all the missing elements: B 14 15 70° A b с

photoshop1234 [79]

Answer:

$B=48.7\\$

$c=61.3$

$b=12$

Step-by-step explanation:

Using sines law for triangles,

$\frac{15}{sinA} =\frac{14}{sinc} =\frac{b}{sinB} \\\\A= 70$

⇒ $\frac{15}{sin70} =\frac{14}{sinC} =\frac{b}{sinB}$

⇒ $\frac{15}{0.9397} =\frac{14}{sinC}=\frac{b}{sinB}$

⇒ $15.9625=\frac{14}{sinC}$

⇒ $SinC=\frac{14}{15.9625}=0.8771$

⇒ $C=Sin^{-1}(0.8771)=61.29$

⇒ $C=61 ~ or ~ 61.30$

$\frac{b}{Sin B}=15.9625$

Now sum of angles a Δ is 180°

A+B+C=180°

$70+B+61=180$

$B=180-131=49~ or ~ 48.7$

$b=sin(48.70)(15.9625)=(0.7547)*(15.9625)= 12.0$

Factor out the GCF from the terms of the polynomial –4y5 + 6y3 + 8y2 – 2y.

WARRIOR [948]

Answer:

Step-by-step explanation:

For example if you have a function f(x) = x - 1, then x = 1 is a zero of this function because using it as x gives 1 - 1 = 0. The Riemann Zeta function has some zeros that are easy to find which are of little interest but there are some other ones that are harder to find which is why the are called non-trivial.
