What is 0.002 1/10 of
ki77a [65]
<span>0.002 1/10 of what
=> 1/10a = 0.002
=> Now, let’s multiply both sides with 10 to find the answer since we’re looking for the 1/10 of what number.
=> 10 x 1/10 a = 10 x 0.002
=>  a = 0.02

Thus, 0.002 is the 1/10 of 0.02 number.
let’s check if we have a correct answer.
To check just do the other way around, Divide our answer by 10.
=> 0.02 / 10
=> 0.002
Therefore, our answer is correct

A sphere has a diameter of 14 ft. Which equation finds the volume of the sphere?
aev [14]

Answer:

The volume of the sphere is 1436 in³

The equation is    

V = ⁴⁄₃ * 3.14 * (7ft)³

Step-by-step explanation:

radius = half of diameter

d = 14ft

r = 14ft / 2 = 7ft

To calculate the volume of a sphere we have to use the following formula:

V = volume

r = radius  = 7ft

π = 3.14

V = ⁴⁄₃πr³

we replace with the known values

V = ⁴⁄₃ * 3.14 * (7ft)³

V = 4.187 * 343 in³

V = 1436 in³

The volume of the sphere is 1436 in³

F(x, y) = x2 + y2 + 4x − 4y, x2 + y2 ≤ 81 find the extreme values of f on the region described by the inequality.
Whitepunk [10]
Take partial derivatives and set them equal to 0:

\nabla F(x,y)=\langle2x+4,2y-4\rangle=\mathbf 0

We find one critical point within the boundary of the disk at (x,y)=(-2,2). The Hessian matrix for this function is

\mathbf H(x,y)=\begin{bmatrix}f_{xx}&f_{xy}\\f_{yx}&f_{yy}\end{bmatrix}=\begin{bmatrix}2&0\\0&2\end{bmatrix}

which is positive definite, and incidentally independent of x and y, so F(x,y) attains a minimum F(-2,2)=-8.

Meanwhile, we can parameterize the boundary by \mathbf r(t)=\langle9\cos t,9\sin t\rangle with 0\le t\le2\pi, which gives

F(x,y)=F(x(t),y(t))=f(t)=81\cos^2t+81\sin^2t+36\cos t-36\sin t=81+36(\cos t-\sin t)

with critical points at

f'(t)=0\implies 36(-\sin t-\cos t)=0\implies\sin t+\cos t=0\implies t=\dfrac{3\pi}4,\dfrac{7\pi}4

At these points, we get

f\left(\dfrac{3\pi}4\right)=81-36\sqrt2\approx30.0883
f\left(\dfrac{7\pi}4\right)=81+36\sqrt2\approx131.9117

so we attain a maximum only when t=\dfrac{7\pi}4, which translates to (x,y)=\left(\dfrac9{\sqrt2},-\dfrac9{\sqrt2}\right).

The pizza shop offers a 15 percent discount for veterans and senior citizens. If the price of a pizza is $12, how would you find
Naya [18.7K]
All you would do is times 12 by .15 or 15% you get 1.8 then all you do is 12 minus 1.8 you get $10.20 that is the price of a discounted pizza 

I hope this helps
