Answer:
Part A) Rectangle
Part B) Triangle
Part C) Cone
Part D) Circle
Step-by-step explanation:
Part A) Perpendicular cross section of a cylinder
The perpendicular cross section of a cylinder is a rectangle
The base of the rectangle is equal top the diameter of the circular base of cylinder and the height of the rectangle is equal to the height of the cylinder
Part B) Perpendicular cross section of a pyramid
Cross sections perpendicular to the base and through the vertex of a pyramid will be triangles
Part C) Shape created when a right triangle is rotated about the y-axis
When a right triangle is rotated about the y-axis, then it forms a cone.
The vertical leg of the triangle becomes the height of the cone.
The horizontal leg of the triangle becomes the radius of the cone.
The hypotenuse of the triangle becomes the slant height
Part D) Parallel cross section of a sphere
The parallel cross section of a sphere is a circle
All cross sections of a sphere are circles
The flight pattern has a total search area of approximately 34900 square miles.Round to the nearest hundred as needed.
Answer:
4x² + 16x + 13
Step-by-step explanation:
4(x² + 4x + 2) + 5
4x² + 16x + 8 + 5
4x² + 16x + 13
Answer:
37
Step-by-step explanation:
You were 6 and he was half which made him 3
So you’re gonna turn 40 he’s gonna be three years younger than you which is 37
Hope I helped
Answer:
0.2x² - 0.2x - 42 = 0
Step-by-step explanation:
Number of counters = x
Number of blue counters =7
Probability, p = required outcome / Total possible outcomes
P(Sam picks blue ) : = 7/x
P(jill picks blue) = 6/(x - 1)
P(Sam picks blue) * P(Jill picks blue) = 0.2
7/x * 6/(x-1) = 0.2
42/x(x - 1) = 0.2
42 / x² - x= 0.2
42 = 0.2(x² - x)
42 = 0.2x² - 0.2x
0.2x² - 0.2x - 42
