Which of the following functions represents f(n), the number of small squares in figure n?
a.f(n)=4n^2+2
b.f(n)=n^2+5
c.f(n)=(n+1)^2+2
d.f(n)=(n+1) (n+2)

Answers

Answer 1

Answer:

c. f(n) = (n+1)^2 + 2

Step-by-step explanation:

It is c. because...

f(n) = (1+1)^2 + 2

        2^2 + 2

        4 + 2 = 6 (first term)

f(n) = (2+1)^2 + 2

        3^2 + 2

        9 + 2 = 11 (second term)

f(n) = (3+1)^2 + 2

        4^2 + 2

        16 + 2 = 18 (third term)

What is Conic Section?

A conic section, conic or a quadratic curve is a curve obtained from a cone's surface intersecting a plane.

An ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant.

An ellipse uses two axis, major and minor.

Major axis is the larger one and minor axis is smaller.

The minor axis of an ellipse is the line that contains the shorter of the two line segments about which the ellipse is symmetrical

Now we come to the question.

Here extreme points of the red line are on the ellipse are more distant than the extreme points of the axis perpendicular to the red line.

Therefore, red line shows the Major axis of the ellipse drawn.

What is the perimeter of one triangle?

Answers

Answer:

Perimeter =84 inches (12 + 35 + 37

Step-by-step explanation:

12 squared + 35  squared = x squared (the other unknown side)

144 +1225 = x squared

1369 = x squared

square root of 1369 = x

x= 37     (37x37= 1369)

Perimeter = 12 +35 + 37 = 84

Help on this plz ASAP!!!

Answers

Answer:

Begin by finding the area of the square, 24x22. This would equal 528. Then, we need to find the area of each circle using the area formula, [tex]\pi[/tex][tex]r^{2}[/tex]. We can plug in the numbers to get [tex]\pi[/tex][tex]3^{2}[/tex]. Multiply 3x3 to get 9[tex]\pi[/tex]. Because there are 4 circular burners, we need to multiply 9[tex]\pi[/tex] by 4 to get 36[tex]\pi[/tex] or 113.04. Now, we can subtract 528 with 113.04 to result with 414.96 or 415, when rounded. So, the answer would be 415 [tex]in.^{2}[/tex]

A model ship is built to a scale of 1 cm : 5m. The length of the model is 25 cm. What is the length of the actual ship?

Answers

Answer:

The length of the actual ship is 125 meters.

Step-by-step explanation:

Scaling

Objects can be represented in a reduced or augmented size by using scaling which is basically multiplying or dividing by a constant factor. We use scaling for example, when representing geographic locations on a map.

A model ship is built to a scale of 1 cm: 5 m. This means that each centimeter of the model represents an actual length of 5 m.

The length of the model is 25 cm, thus the real ship has a length of 25*5 = 125 m.

The length of the actual ship is 125 meters.
