The area of a circle with radius r is given by A = π r2. Find the area of a circle with radius 7 centimeters. Use 3.14 for π..
scZoUnD [109]

Step-by-step explanation:

Hey there!

Given;

Radius of a circle (r) = 7cm

Now;

We know that;

Area of circle (a) = π*(r^2)

= 3.14*(7^2)

= 3.14*49

= 153.86 cm^2

Therefore, the area of a circle is 153.86 cm^2.

Graph the equation.<br>y<br>=<br>2<br>(<br>x<br>−<br>4<br>)<br>2<br>+<br>5<br>y=2(x−4) <br>2<br> +5
olga nikolaevna [1]

Answer:

Step-by-step explanation:

I believe you meant y = 2(x − 4)^2 + 5.  Use the symbol ' ^ " to indicate exponentiation.  This equation has the vertex form of the equation of a quadratic.  The  x-coordinate of the vertex is 4 and the y-coordinate is 5.  Thus, the vertex is at (4, 5).  The multiplier 2 stretches the graph vertically by a factor of 2.

To aid us in graphing this function, find the x- and y-intercepts:

If x = 0, y = 2(-4)^2 + 5, or 37.  Therefore the y-intercept is at (0, 37).  

If y = 0, then

2(x − 4)^2 + 5 = 0,

2(x − 4)^2 = -5  But a square cannot be negative, so there is no x-intercept in this case.

To graph this function, plot the vertex (4, 5) and the y-intercept (0, 37).  Take advantage of symmetry and find another point across x = 4 from (0, 37):  It is (8, 37).
