I believe the degree of the polynomial is 3 because that is the highest exponent
Answer:
56√93 ≈ 540 ft²
Step-by-step explanation:
The roof is made up of 4 congruent isosceles triangles. Since the roof extends 2 ft over the edge of the cottage on each side, then the base of each triangle is 26 + 2 = 28 ft.
Let's calculate the area of one of the triangles and then just multiply by 4. See attachment. Drop a perpendicular from the vertex of a triangle to its base. We now have the triangle broken up into two right triangles. The hypotenuse is 17 ft and one of the legs of the right triangle is 28 / 2 = 14 ft. Then the height / other leg is:
We now have the dimensions of each triangle: the height is √93 and the base is 28. The area of a triangle is: A = (1/2) * b * h, so we have the following.
A = (1/2) * b * h
A = (1/2) * 28 * √93 = 14√93
Multiply this by 4:
14√93 * 4 = 56√93
The total surface area is 56√93 ≈ 540 ft².
Answer:
inverse i believe, because the numbers are switched around on the right side of the equal sign.
Step-by-step explanation:
Answer:
<u>1. C.</u>
<u>2. B.</u>
<u>3. A.</u>
Step-by-step explanation:
First situation given:
An adult and 5 children rent skates. It costs $ 4 per adult for skates and a total of $ 16.
Correct equation: C
<u>4 + 5 x = 16</u>
Second situation given:
It costs Mikael $ 4 to make a bike bag, and he sells each for $ 5. He has made a profit of $ 16, so far.
Correct equation: B
<u> ( 5 − 4 ) x = 16</u>
Third situation given:
It was 16°C. It began falling 4°C per hour until it reached 5°C.
<u>Correct equation: A</u>
<u>16 − 4 x = 5</u>
