Answer:
312π mm3
Step-by-step explanation: yes
The required volume of the composite figure of the sphere on the top of the cone is 312π mm³. Option c is correct
The sphere is stacked on top of a cone. They both share a circular base. The radius of the circle is 6 millimeters. The height of the cone is 14 millimeters. The volume of the composite figure is to determine.
Volume is defined as the ratio of the mass of an object to its density.
Volume of composite figure = Volume of semi-sphere + Volume of cone
= 2/3πr³ + 1/3πr²h
= 2/3*6³π + 1/3*6²*14π
= 312π mm³
Thus, the required volume of the composite figure of the sphere on the top of the cone is 312π mm³.

Solve dy/dx = (1-x)(1-y)
Answer:
[tex]y=1-e^{c_{2}}}*e^{-x} *e^{x^2}[/tex]
Step-by-step explanation:
We begin with the differential equation [tex]\frac{dy}{dx} =(1-x)(1-y)[/tex]
Firstly, we need to get the [tex]y[/tex] and [tex]dy[/tex] as well as the [tex]x[/tex] and [tex]dx[/tex] on the same sides as each other
To do this, we can multiply each side by [tex]dx[/tex] and divide each side by [tex](1-y)[/tex]
Doing this will give us the following differential
[tex]\frac{1}{1-y} dy=(1-x)dx[/tex]
Now, we can integrate each side
[tex]\int\limits\frac{1}{1-y} \, dy =\int (1-x) \, dx\\\\-ln(1-y)=x-x^2+c_{1}[/tex]
Now, we need to solve for y
[tex]-ln(1-y)=x-x^2+c_{1}\\\\ln(1-y)=x^2-x+c_{2} \\\\1-y=e^{x^2-x+c_{2}} \\\\y=1-e^{x^2-x+c_{2}}\\\\y=1-e^{c_{2}}}*e^{-x} *e^{x^2}[/tex]

Answer:
17 cm
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 +b^2 = c^2 where a and b are the legs and c is the hypotenuse
8^2 + 15^2 =c^2
64+225 = c^2
289 = c^2
Take the square root of each side
sqrt(289) = sqrt(c^2)
17 = c
Answer:
The hypotenuse is 17cm
Step-by-step explanation:
Pythagoras theorem is : [tex]a^{2} +b^{2} =c^{2}[/tex]
To work out the hypotenuse of this triangle you would first need to know Pythagoras theorem. The theorem states that [tex]a^{2} +b^{2} =c^{2}[/tex]. A and B are the 2 lengths given in this question and c is the hypotenuse.
The first step in working out the hypotenuse is to square the base of 8, this gives you 64.
Then you would need to square the height of 15, this gives you 225. This is because we are substituting the values into a and b.
Then the next step is to add the values of 64 and 225, this gives you 289.
The final step is to root the value of 289, which gives you 17cm. This is because as c is the hypotenuse while the value worked out is c squared and so to work out c you would have to root it.
1) Square the base of 8cm.
[tex]8^{2} =64[/tex]
2) Square the height of 15cm.
[tex]15^{2} =225[/tex]
3) Add 64 and 225.
[tex]64+225=289[/tex]
4) Root the value of 289.
[tex]\sqrt{289}= 17cm[/tex]
Which is the graph of f(x) = x2 – 2x + 3?
Answer:
Step-by-step explanation:
We cannot factor this function out which tells us that there are no zeros. The graph backs this up because we can see that there are none. The easiest way to graph this would start by plugging in points and making a table for yourself.
Lets start by plugging in -1.
(-1)^2-2(-1)+3 =6, this means we have a point at (-1,6).
Now lets plug in 0.
(0)^2-2(0)+3= 3 (0,3)
For plugging in 1
(1)^2-2(1)+3=2 (1,2) (this happens to be the vertex)
And lastly lets plug in 2
(2)^2-2(2)+3=3 (2,3)
Depending on how many points are needed, keep plugging in numbers like we did above.

The parallelogram shown below has an area of 404040 units^2 2 squared.
Find the missing base.
Question:
The parallelogram shown below has an area of 40 units squared.
Find the missing base.
Answer:
See Explanation Below
Step-by-step explanation:
The question is incomplete as the diagram which shows the dimension of the parallelogram is not attached.
However, I'll give a general explanation on how to get the base of the parallelogram. If you follow this explanation, you'll get the right answer regarding your question.
The area of a parallelogram is calculated as thus.
Area = Base * Height
Given that the area = 40 units²
Let's assume the height of the parallelogram is 10 unit.
All you need to do is to plug in these values in the formula above..
Area = Base * Height becomes
40 = Base * 10
Divide both sides by 10
40/10 = Base * 10/10
4 = Base
Hence, Base = 4 units
Or take for instance the height is 5 units.
You'll still follow the simple steps as it is above.
Area = Base * Height becomes
40 = Base * 5
Divide both sides by 5
40/5 = Base * 5/5
8 = Base
Hence, Base = 8 units

The dimensions that could be the box with a volume of 24 cubic centimeters are:
8cm long, 1cm wide, 3cm high
2cm long, 2cm wide, 6cm high
Options A and C are the correct answer.
We have,
To determine if the given dimensions could represent the box with a volume of 24 cubic centimeters, calculate the volume for each option and check if it matches the given volume.
Let's calculate the volume for each option:
Option A:
Length = 8 cm, Width = 1 cm, Height = 3 cm
Volume = Length × Width × Height
Volume = 8 cm × 1 cm × 3 cm
Volume = 24 cubic cm
Option A could be the dimensions of the box
Option B:
Length = 10 cm, Width = 4 cm, Height = 10 cm
Volume = Length × Width × Height
Volume = 10 cm × 4 cm × 10 cm
Volume = 400 cubic cm
Option B does not have a volume of 24 cubic cm.
Option C:
Length = 2 cm, Width = 2 cm, Height = 6 cm
Volume = Length × Width × Height
Volume = 2 cm × 2 cm × 6 cm
Volume = 24 cubic cm
Option C could be the dimensions of the box.
Therefore,
The dimensions of the box with a volume of 24 cubic centimeters are:
8cm long, 1cm wide, 3cm high
2cm long, 2cm wide, 6cm high

Each steak surface requirement = 0.25 square feet of the grill.
Maximum number of steaks mike can grill at
2.5 feet
2 feet and
3.5 feet
Solution.

= 2.5 / 0.25
= 10 steaks
At 2 feet
= 2 / 0.25

What is the measure of 1?
95°
90°
80°
85°
Answer:
85°
Step-by-step explanation:
We need to use the angle fact that angles in a quadrilateral add up to 360° and that a right angle is 90°, using this information we can for an equation to find the value of 1. Lets call "1" x so we don't confuse it with an angle. So,
x + 85 + 100 + 90 = 360
In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we took away 90 only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.
x + 85 + 100 + 90 = 360
→ Simplify equation
x + 275 = 360
→ Minus 275 from both sides to isolate x
x = 85
The measure of angle '1' is 85°
Answer:
85°
Step-by-step explanation:
∠1+85°+100°+90°= 360°
∠1 = 360°- 275°= 85°
∠1 =85°
