P.S. Hello from Russia
The solutions to the system are -11.3 and 11.3.
The length of one leg of the sun shade is 11.3 feet.
Steps:
graph y=1/2 x^2
graph y=64
zoom out.
find the points of intersection.
done.
In bank A, after one year this would be the amount in the bank:
<span>$7,000 x 1.04 = $7280. </span>
<span>He has gained %280 interest. This means you'd need $1000 interest from bank B. </span>
<span>$13,000 would go into bank B... </span>
<span>If Seth's interest rate was 8.69% you could calculate the interest as: </span>
<span>(13000 x 1.0869) - 13,000 = $1129.70 which is a little much (but who'd complain). </span>
<span>This means the interest is lower than this, if it was 7.69% you could just substitute it into the same equation to find that he would get $999.70 interest. This isn't exactly $1000 but it is the most accurate answer to the nearest $100 :) He would then get $1279.70 interest altogether.. just 30 cents short</span>
Answer:
S = 2 pi (3) squared + 2 pi (3) (14)
Step-by-step explanation:
The formula for the area of a circle is ...
A = πr²
The cylinder has two circular bases with radius 3 cm, so their combined area in square centimeters is ...
A = 2π(3²) . . . . . . matches a term in the last choice
__
The lateral area of the cylinder is the product of the height and the circumference of the base. That is ...
A = 2πrh
For the given radius and height, the lateral area in square centimeters is ...
A = 2π(3)(14) . . . . . . matches a term in the last choice
__
The total surface area is the sum of the areas of the bases and the lateral area, so is ...
S = 2π(3²) +2π(3)(14) . . . . . matches the last choice
_____
<em>Comment on answer choices</em>
We could choose the correct answer based solely on the area of the bases of the cylinder.
