select all of the following that could be cross-sections of the cone shown below
circle
oval
parabola
rectangle
trapezoid
triangle
Answer:
oval, triangle
hope it helped you ☺
The cross sections of the cone shown can be circle, oval, parabola and triangle.
What is Cross Section?Cross section of a figure or shape can be defined as a plane intersecting with the figure. The resulting shape formed in the intersection part is termed as cross section.
Given shape is a cone.
When a cone is intersected vertically, then the cross section formed is triangle.
When the cone is intersected through the straight horizontal line, we get the cross section as circle.
We will get an oval shape when the cone is intersected with the plane with a given slant by not touching the base.
A parabola shape is formed when a slant plane intersects by touching the base
Hence the cross sections of the given cone are circle, oval, parabola and triangle.

Find the area of the shaded region. The radius of the large circle is 10 m. Round answer to the nearest hundredth.
Answer:
hello the figure related to your question is missing attached below is the missing figure
answer : 157.08 m^2
Step-by-step explanation:
Calculate the area of the shaded area
= Area of the large circle - Areas of the small circles
= (( [tex]\frac{\pi }{4}[/tex] ) * D^2) - 2( ( [tex]\frac{\pi }{4}[/tex] ) * d^2 ) given that the small circles are congruent
= (( [tex]\frac{\pi }{4}[/tex] ) * 20^2 ) - 2 ( ( [tex]\frac{\pi }{4}[/tex] ) * 10^2 )
= 314.16 - 157.08
= 157.08 m^2
For her science fair project, Emily
conducted an experiment to investigate
the effects of watering on tomato plants.
She varied the amount of water given to
the plants and measured each plant's
height after two weeks. Emily
hypothesized that the more water she
added, the taller her tomato plants would
be.
1. Was Emily's hypothesis correct? Explain
your answer.
2. According to Emily's data, what is the
optimal weekly amount of water for
tomato plant growth? Explain your answer.
Answer:1 yes it is correct because the more water you give a plant the helter it is

Rhombus L M N O is shown. Diagonals are drawn from point L to point N and from point M to point O and intersect at point P. The length of L M is 3 x minus 3 and the length of M N is x + 7. What is the perimeter of rhombus LMNO? 20 units 24 units 40 units 48 units
Answer:
48units
Step-by-step explanation:
Find the diagram of the rhombus attached
From the diagram, LM = MN
Hence;
3x - 3 = x + 7
Find x
Add 3 to both sides
3x - 3 + 3 = x + 7 + 3
3x = x + 10
3x - x = 10
2x = 10
x = 10/2
x = 5
LM= 3x - 3
LM = 3(5) - 3
LM = 12
Since LM = MN, then MN = 12
Since all the sides of the rhombus are equal then;
Perimeter of the rhombus = LM + MN + NO + OL
Perimeter of the rhombus = 12 + 12 +1 2 + 12
Perimeter of the rhombus = 48units
Answer:
48 Units is the answer

Complete the function for this graph:
Answer:
The equation is:
f(x) = Ix + 3I - 2
Step-by-step explanation:
For a function like:
f(x) = Ix - kI + c
k is the x-value where the vertex is, and c is the y-value where the vertex is.
In the graph we can see that the vertex is in the point (-3, -2)
then:
x-value = -3 = k
y-value = -2 = c
Replacing those in the equation for the function:
f(x) = Ix - (-3)I - 2
f(x) = Ix + 3I - 2

Find the equation parallel to y = -x - 5 and passing through (-3, -3)
Answer:
y = -x - 6
Step-by-step explanation:
If it's parallel, then it means that the slope will remain the same. The slope is
-1.
To find the y-intercept, you need to plug the coordinates into the equation,
y = -1x + b
-3 = -1(-3) + b
-3 = 3 +b
-6 = b
The equation is y = -x - 6

If we multiply a number by 5, then we add it by 3.5, and we divide the result by 2, and from the new result we subtract 7.6 we obtain 6.65. Find out the number.
Answer:
the number is 5
Step-by-step explanation:
((n x 5 + 3.5) ÷ 2) -7.6 = 6.65
( 5n + 3.5) ÷ 2 = 14.25
5n + 3.5 = 28.5
5n = 25
