John can complete a paper route in 20 minutes.

John's 1 minute work = 1/20 , so rate =1/20 job/minute

Steve can complete the same route in 30 minutes

Steve's 1 minute work =1/30, so rate =1/30 job/minute

Together DATA:

Time = y min/job ; Rate = 1/y job/min

rate + rate = together rate

1/20 + 1/30 = 1/y

(30+20)/600 = 1/y

50/600

5/60 = 1/y

y = 60/5 = 12 minutes (time for this to do the job together)

the vertex of the parabola represented by f(x)=x^2-2x+6 has coordinates (1,5). Find the coordinates of the vertex of the parabol
Sever21 [200]
Plug \ in \ x+3 \ into \ f(x) \ to \ get \ g(x)
\\\ g(x) = (x+3)^2-2(x+3)+6
\\\ g(x)= x^2+6x+9 -2x-6+6
\\\ g(x) = x^2+4x+9
\\\ -\frac{b}{2a} --\ \textgreater \  vertex
\\\ \frac {-4}{2}
\\\ x \ coordinate = -2, plug \ it \ back \ into \ g(x)
\\\ (-2)^2+4(-2)+9
\\\ 4-8 + 9
\\\ y \ coordinate = 5
\\\ \boxed{(-2,5)}

A tangent and a secant x = ?
guajiro [1.7K]

x = 45°

Solution:

Given data:

Measure of larger arc = 152°

Measure of smaller arc = 62°

<em>If a tangent and a secant intersect at the exterior of a circle then the measure of angle formed is one-half the positive difference of the measures of the intercepted arcs.</em>

$\Rightarrow  x = \frac{1}{2}(\text{ larger arc }- \text{smaller arc} )

$\Rightarrow  x = \frac{1}{2}(152^\circ-62^\circ)

$\Rightarrow  x = \frac{1}{2}(90^\circ)

⇒ x = 45°

The value of x is 45°.

Given ABCE is a rectangle, D is the midpoint of CE<br> Prove AD =~ BD
Bas_tet [7]

Since the congruent operator is ≅ and since AD is congruent to BD, I'm going to assume that you want to prove that AD is congruent to BD.    
1. DE is equal to CD by definition since D is the midpoint of CE.  
2. AE is equal to BC since opposite sides of a rectangle are equal to each other.  
3. Angle AEC is equal to Angle BCE since all angles in a rectangle are right angles and all right angles are equal to each other.  
4. Triangles ADE and BDC are congruent to each other because we have SAS congruence for both triangles.  
5. AD is congruent to BC since they're corresponding sides of congruent triangles.
