Which of the following is a solution of x2 + 2x + 8? (1 point)

Mrrafil [7]

Answer

−1 + i times the square root of 7

Explanation

x² + 2x + 8

I will use the complete square method to find the value of x.

x² + 2x + 8

x² + 2x = -8

x² + 2x + (2/2)² = -8 + (2/2)²

x² + 2x + 1 = -7

(x + 1)² = -7

x + 1 = √(-7)

x = √(-7) - 1

= i√7 - 1

= -1 + i√7

−1 + i times the square root of 7

(b) The globe has a radius of 28.5 cm. Find the surface area of the globe. Round your answer to two decimal places. Use:

damaskus [11]

Answer:

$\boxed {\boxed {\sf 10,207.03 \ cm^2}}$

Step-by-step explanation:

Surface area is the total area of the surface of an object. A globe is a sphere and the formula for calculating a sphere's surface area is:

$SA= 4 \pi r^2$

The radius (r) of the globe is 28.5 centimeters. Substitute this value into the formula.

r= 28.5 cm

$SA= 4 \pi ( 28.5 \ cm)^2$

Solve the exponent. Multiply the number by itself.

(28.5 cm)²= 28.5 cm * 28.5 cm = 812.25 cm²

$SA= 4 \pi (812.25 \ cm^2)$

Multiply 4, pi and 812.25 centimeters together.

$SA= 12.56637061 (812.25 \ cm^2)$

$SA= 10207.03453 \ cm^2$

Round to two decimal place or the hundredth place. The 4 in the thousandth place to the right (10207.03453) tells us to leave the 3 in the hundredth place (10207.03453).

$SA \approx 10207.03 \ cm^2$

The surface area of the globe is approximately 10,207.03 centimeters squared.
