Answer:
45/7
Step-by-step explanation:
The ratio of volumes is the cube of the scale factor for similar figures.
__
sf³ = (729 m³)/(2.744 m³) = 9³/1.4³
sf = ∛(9³/1.4³) = 9/1.4 = 45/7
The scale factor between the larger and smaller cubes is 45/7.

Answer:
49°
Step-by-step explanation:
The marked angles are "vertical" angles. They have the same measure.
∠TGF = ∠HGM = 49°
_____
You don't need to know the value of p to answer this question. It is 7.
Answer:
∠TGF = 49°
Step-by-step explanation:
From the diagram, we get that ∠TGF is equal to ∠MGH because they are vertical angles.
Hence,
⇒ ∠TGF = ∠MGH
⇒ ∠TGF = 49°

HELP Sam measures the height of 7 different scoops of ice cream. The mean of the heights was 3.8 cm. Which of the following best describes the mean?
Answer:
B
Step-by-step explanation:
mean=(a+b+c+d+e+f+g)/7
Sam measures the height of 7 different scoops of ice cream. The mean height was 3.8 cm. If all the scoops are evenly distributed, they would all be 3.8 cm tall.
How to find the mean value of a data set?The mean value of the data set is the ratio of the sum of the data set's values to the number of values it has.
If the data set consists of values
x_1, x_2, ..., x_n
, then we get the mean value as:
[tex]\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}[/tex]
Sam measures the height of 7 different scoops of ice cream. The mean height was 3.8 cm.
[tex]\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}[/tex]
mean=[tex]\dfrac{(a+b+c+d+e+f+g)}{7}[/tex]
Therefore, If all the scoops are evenly distributed, they would all be 3.8 cm tall.

What are Complex numbers?A complex number is the sum of a real number and an imaginary number. A complex number is of the form a + ib and is usually represented by z. Here both a and b are real numbers. The value 'a' is called the real part which is denoted by Re(z), and 'b' is called the imaginary part Im(z).
Since we have given : [tex]z_1[/tex]==4-4[tex]\sqrt{3i}[/tex] and [tex]z_2[/tex]= -16i
The difference of z1 - z2 would be:
So,
[tex]z_1-z_2[/tex] = 4-4[tex]\sqrt{3i}[/tex] - (-16i)
[tex]z_1-z_2[/tex] =4-4[tex]\sqrt{3i}[/tex]+16i
[tex]z_1-z_2[/tex] =4-4([tex]\sqrt{3i}[/tex] -4i)
Hence, [tex]z_1-z_2[/tex]= 4-4([tex]\sqrt{3i}[/tex]-4i)

please help me Find the slope
Answer:
-1/2
Step-by-step explanation:
let's look at the change from the red point to the blue point
thus, (x₁, y₁) = red point = (-4, 1) and (x₂, y₂) = blue point = (-2, 0)
note that (x₁, y₁) and (x₂, y₂) can be interchanged
slope = change in y / change in x = (y₂-y₁)/(x₂-x₁) = (0-1) / (-2-(-4)) = -1/2 as our slope
1. (a) Solve the differential equation (x + 1)Dy/dx= xy, = given that y = 2 when x = 0. (b) Find the area between the two curves y = x2 and y = 2x – x2.
(a) The differential equation is separable, so we separate the variables and integrate:
[tex](x+1)\dfrac{dy}{dx} = xy \implies \dfrac{dy}y = \dfrac x{x+1} \, dx = \left(1-\dfrac1{x+1}\right) \, dx[/tex]
[tex]\displaystyle \frac{dy}y = \int \left(1-\frac1{x+1}\right) \, dx[/tex]
[tex]\ln|y| = x - \ln|x+1| + C[/tex]
When x = 0, we have y = 2, so we solve for the constant C :
[tex]\ln|2| = 0 - \ln|0 + 1| + C \implies C = \ln(2)[/tex]
Then the particular solution to the DE is
[tex]\ln|y| = x - \ln|x+1| + \ln(2)[/tex]
We can go on to solve explicitly for y in terms of x :
[tex]e^{\ln|y|} = e^{x - \ln|x+1| + \ln(2)} \implies \boxed{y = \dfrac{2e^x}{x+1}}[/tex]
(b) The curves y = x² and y = 2x - x² intersect for
[tex]x^2 = 2x - x^2 \implies 2x^2 - 2x = 2x (x - 1) = 0 \implies x = 0 \text{ or } x = 1[/tex]
and the bounded region is the set
[tex]\left\{(x,y) ~:~ 0 \le x \le 1 \text{ and } x^2 \le y \le 2x - x^2\right\}[/tex]
The area of this region is
[tex]\displaystyle \int_0^1 ((2x-x^2)-x^2) \, dx = 2 \int_0^1 (x-x^2) \, dx = 2 \left(\frac{x^2}2 - \frac{x^3}3\right)\bigg|_0^1 = 2\left(\frac12 - \frac13\right) = \boxed{\frac13}[/tex]

HELPPPPP QUICKLYYY !!! The picture shows a cylinder of height x which has been inscribed in a sphere of radius r. Find the volume of a cylinder in terms of x.
See attached. We can draw a right triangles contained within both shapes.
The triangle has height x (same as the cylinder), base 2r (same as the diameter of the cylinder), and hypotenuse 6 (same as the diameter of the sphere).
Since it's a right triangle, the Pythagorean theorem holds and we have
x² + (2r)² = 6²
which we solve for r to get
x² + 4r² = 36
4r² = 36 - x²
r² = 9 - x²/4
r = √(9 - x²/4)
Then the volume of the cylinder, whose height is x and whose base has radius r, is
π r² x = π (9 - x²/4) x = (36x - x³) π/4
