A rectangle with a height greater than twice its width.

Answer:

Step-by-step explanation:

Given that a two dimensional shape can be rotated about the y-axis to create a cylinder which has a smaller diameter than height

Whenever a vertical line with equation x=a is rotated about y axis from y =b to y=c we get a right circular cylinder.

The cylinder would have radius as a and height as c-b

Whenever we want the diameter to be less than height we must select a,b,c such that

2a <b-c

In this case we would get the required type of cylinder.

r-ruslan [8.4K]

Answer: 4 months

Look at it this way: 6 books in a group. How many groups are there? well this is multiplication. Just add 6 a bunch of times until you get 24. You will add 6+6+6+6. There are 4 6's. This means, there are 4 months, with 6 books each month.

The rate constant for this first‑order reaction is 0.740 s − 1 0.740 s−1 at 400 ∘ C. 400 ∘C. A ⟶ products A⟶products How long, i
sesenic [268]

Answer:

1.668 S

Step-by-step explanation:

We are given that

A\rightarrowProduct

For first order reaction,

t=\frac{1}{k}ln\frac{A_0}{A}

t=\frac{2.303}{k}log\frac{A_0}{A}

Rate constant=k=0.740s^{-1}

Temperature=T=400^{\circ}

We have to find the time taken by the reaction when concentration of A to decrease from 0.790 M to 0.230 M.

A_0=0.79 M

A=0.230

Substitute the values then we get

t=\frac{2.303}{0.740}log\frac{0.79}{0.23}

t=1.668 s

Hence, it would take 1.668 s for the concentration of  A to decrease from 0.790 M to 0.230 M.

Pls answer 1. 2. 3.
Arisa [49]
1.You can see through the comparison to a mountain, that the grandpa is y’all and always the ‘looming’ (hovering) over the speaker you can see that the speaker does not speak much around his grandpa, as he is “silent as a stone”

2.These details show that the speaker is impressed by his grandpa and looks up to him the way a stone would look up to a mountain-it shows that he hopes one day he will grow to be like his grandpa

3.the theme of this poem is shown through the way the speaker looks at his grandpa and the shed. The shed needs more than paint because it’s so old, which relates to his grandpa and the theme of growing older

Evaluate the polynomial function when H=3<br> f(h)=4h^3-3h^2+5h-16
tester [92]

Answer:

80

Step-by-step explanation:

f(3)=4(3)^3-3(3)^2+5(3)-16

f(3)=4(3*3*3)-3(3*3)+15-16

f(3)=4(27)-3(9)+15-16

f(3)=108-27+15-16

f(3)=81+15-16

f(3)=96-16

f(3)=80
