Hello from MrBillDoesMath!

Answer:

x = 31

Discussion:

angle A + angle C + angle B = 180 (180 degrees in a triangle)

angle A + 57 + 61 = 180 => (substitution)

angle A + 118 = 180 =>

angle A = 180 -118 = 62

By the congruence statement, angle A = angle D = 2x so

62 = 2x =>

x = 31

Thank you,

MrB

alex41 [277]

Answer:

224 in^3

Step-by-step explanation:

The foruma appropriate to the calculation of the cone's volume is ...

V = (1/3)Bh

where B represents the area of the base and h represents the height.

For your numbers, this is ...

V = (1/3)·(48 in^2)(14 in) = (16 in^2)(14 in) = 224 in^3

Talulah is an ecologist who studies the change in the penguin population of Antarctica over time. She

blondinia [14]

Answer:

P(t) = 27000 - 4*t

Step-by-step explanation:

Over a period of time, if we know the population at certain time, and the rate of change of the population, we can express the function describing such population by means of these two parameters

Then:

P(t) = P₀ + 4*t

In our case

P(t) = 27000 - 4*t

Sign minus is for decreasing population t is in months, 4 is the rate of change and finally 27000 was population the first time Talulah counted the population

Determine whether or not F is a conservative vector field. If it is, find a function f such that F = ∇f. (If the vector field is

kodGreya [7K]

We're looking for a scalar function $f(x,y)$ such that $\nabla f(x,y)=\vec F(x,y)$ . That is,

$\dfrac{\partial f}{\partial x}=2x-6y$

$\dfrac{\partial f}{\partial y}=-6x+6y-7$

Integrate the first equation with respect to $x$ :

$f(x,y)=x^2-6xy+g(y)$

Differentiate with respect to $y$ :

$-6x+6y-7=-6x+\dfrac{\mathrm dg}{\mathrm dy}\implies\dfrac{\mathrm dg}{\mathrm dy}=6y-7$

Integrate with respect to $y$ :

$g(y)=3y^2-7y+C$

So $\vec F$ is indeed conservative with the scalar potential function

$f(x,y)=x^2-6xy+3y^2-7y+C$

where $C$ is an arbitrary constant.

Zanzabum

Answer:

9 cm.

Step-by-step explanation:

Let x be the number of hours.

We have been given that after a winter storm, the depth of the snow on cherry street was 10 cm. Then, the snow started melting at a rate of $\frac{1}{3}$ , so the snow melted in x hours will be $\frac{1}{3}x$ .
