Answer: 6) =approx 156.60 cm
7) =approx 687.68'
Step-by-step explanation:
6. Let the shortest side of the triangle is AB=45 cm ( ∡A=90° so ABCD is a rectangle). The middle side AD=150 cm. The longest side is BD
The length of BD can be calculated using Phitagore theorem because triangle BAD ia right angle.
BD=sqrt(AD²+AB²)=sqrt(2025+22500)=approx 156.60 cm
7. So we can create the model of the situation described in this problem.
The model is right-angle triangle ABC with side AB=520' ,side AC=450', right angle is A. So we have to find the length of side BC .
BC is hypotenuse of triangle ABC. We can find it using Phitagore theorem again.
BC=sqrt(AC²+AB²)=sqrt(450²+520²)=sqrt(472900)=approx 687.68'
A parabola has a characteristic arc appearance when graphed on a Cartesian plane. The vertex is the center of the arc. It is either the maximum point or the minimum point, depending on the form of the equation. Since the parabola passes through the vertex, then it is still valid to be substituted as a point. You would still come up with the same answer for coefficient a.
Answer:
Step-by-step explanation:
Step one:
given data
The charge is $45 to install the cable box and $60 for each month of service
Required
The linear expression for the situation.
Step two:
let the number of months be x and let the total charges be y
Hence the expression for the total charges is
Answer: 18.85
Step-by-step explanation:
So perimeter of a regular circle is 2pi(r) where r is radius right so 2(3.14)(6)= 37.7 now since its a semicircle just divide by 2 so 37.7/2 is 18.85
