X would equal 10 if you're meaning it's 20/x as a fraction with the outcome of 2.
Answer:
B) 2^3 x 3 x 5
D) 3^2 x 5^2
Step-by-step explanation:
6 and 10 are composite numbers, not prime, so the answer choices containing those factors can be eliminated. The remaining choices are shown above.
Step-by-step explanation:
ok so as u know the angles of a triangle add up to 180.
So we will be using that for help.
S+R+T=180
12x+13x+12x-4+2-3=180
37x-5=180
37x=185
x=5
Now we will plug in the value for x to find each angle
S= 13(5)-4
=61
T=12(5)-3
=57
R=12(5)+2
=62
Hope this helped:)
Answer:
49π
Step-by-step explanation:
The equation of the area of a circle is πr^2
π= 3.14
r= 1/2d
Because d=14 the radius is
r=1/2(14) or r=7
Therefore the equation of the area of the circle is π7^2
Because of the order of operations we can evaluate that 7^2= 49
49*π= 49π
We have that
<span>focus (-5, 3) and vertex (-5, 6)
</span>As the vertex <span>(−5,6)</span><span> and focus </span><span>(−5,3)</span><span> share same abscissa </span><span>−5</span><span>, parabola has axis of symmetry as </span><span>x=−5
</span>Hence, equation of parabola is of the type <span><span>(y−k)</span>=a<span>(x−h)</span></span>²<span>,
where </span><span>(h,k)</span><span> is vertex
</span>Its focus then is <span>(h,k+<span>1/(<span>4a)</span></span>)
(h,k)=(-5,6)
</span>(h,k+1/(4a))=(-5,3)
(y−k)=a(x−h)²-----> (y−6)=a(x+5)²
k+1/(4a)=3------> 6+1/(4a)=3-----> 1/(4a)=-3-----> a=-1/12
(y−6)=a(x+5)²------> (y−6)=(-1/12)*(x+5)²
the answer is(y−6)=(-1/12)*(x+5)²
