50 POINTS! The fifth term of an arithmetic sequence is 11 and the tenth term is 41. What is the first term?

Oxana [17]

The common difference d is

(41–11) / (10–5) = 6.

The first term is

11 - 6(5–1) = -13.

so , the first term is -13

If you transform x 2 + y 2 = 25 into 4x 2 + 4y 2 = 25, which option below describes the effect of this transformation on the rad

FromTheMoon [43]

Answer

c. It divides the radius by 2.

Explanation

The general equation of a circle is

(x-h)² + (y-k)² = r²

Where (h, k) makes the coordinates of the circle and r the radius.

x² + y² = 25 For this equation,

center (0, 0)

Radius = √25 = 5

4x² + 4y² = 25 First simplify this equation

4x² + 4y² = 25 ⇒ x² + y² = 25/4

center (0, 0)

Radius = √(25/4) = 5/2

The radius has been divided by 2

A cone has a height of 2.5 in. and a radius of 5 in. What is the volume of the cone? (Use 3.14 for Pi. Round the answer to two d

Stells [14]

Answer:

$V =\frac{1}{3} \pi r^2 h$

And replacing we got:

$V = \frac{1}{3} (3.14) (5in)^2 (2.5in) = 65.42 in^3$

And the best option would be:

65.42 Inches cubed

Step-by-step explanation:

For this case we have the following info given:

$h =2.5 in$ represent the height of the cone

$r = 5 in$ represent the radius

And the volume of the cone is given by;

$V =\frac{1}{3} \pi r^2 h$

And replacing we got:

$V = \frac{1}{3} (3.14) (5in)^2 (2.5in) = 65.42 in^3$

And the best option would be:

65.42 Inches cubed
