Select all that apply.<br> Which words describe the square root of 100?

abruzzese [7]

The square root of a number is any number that when multiplied against itself becomes the number under symbol denoting for the square root operation.

The number 10 is the result of the square root operator applied to the number 100 because 10 * 10 = 100.

The number 10 is a natural number because natural numbers are positive integers. It is also an integer, whole number, and rational.

Hope this answer helps!

How much is a book that is regularly priced at $62.85 when it is 1/3 off?

Marina86 [1]

Answer:

$41.9

Step-by-step explanation:

divide $62.85 and get 20.95 which is 1/3 of it so then you just subtract $20.95 from $62.85 and get 41.9

A grasshopper jumps off a tree stump. The height, in feet, of the grasshopper above the ground after t seconds is modeled by the

klasskru [66]

Answer:

Hence, Grasshopper will land on the ground after 1.5 sec.

Step-by-step explanation:

It s given that:

The height, in feet, of the grasshopper above the ground after t seconds is modeled by the function:

$h(t)=-t^2+\dfrac{4}{3}t+\dfrac{1}{4}$

Now we are asked to find:

In how many seconds will the grasshopper land on the ground?

i.e. we have to find the value of t such that h(t)=0

i.e.

$-t^2+\dfrac{4}{3}t+\dfrac{1}{4}=0$

i.e. we need to find the roots of the given quadratic equation.

On solving the quadratic equation or plotting it's graph we could observe that the point where h(t)=0 are:

$t=-\dfrac{1}{6},t=\dfrac{3}{2}$

As time can't be negative hence we will consider:

$t=\dfrac{3}{2}=1.5sec$

Hence, grasshopper will land on the ground after 1.5 sec.

Two chemicals A and B are combined to form a chemical C. The rate, or velocity, of the reaction is proportional to the product o

Keith_Richards [23]

Answer:

32.1 g

Step-by-step explanation:

In each 3 grams of C, there are 2 grams of A and 1 gram of B. So, for some amount C, the amount remaining of A is 40 -(2C/3), and the amount remaining of B is (50 -C/3). Since the reaction rate is proportional to the product of these amounts, we have ...

C' = k(40 -2C/3)(50 -C/3) = (2k/9)(60 -C)(150 -C) . . . for some constant k

This is separable differential equation with a solution of the form ...

ln((150 -C)/(60 -C)) = at + b

We know that C(0) = 0, so b=ln(150/60) = ln(2.5). And we know that C(10) = 20, so ln(130/40) = 10a +ln(2.5) ⇒ a = ln(1.3)/10

Then our equation for C is ...

ln((150 -C)/(60 -C)) = t·ln(1.3)/10 +ln(2.5)

For t=20, this is ...

ln((150 -C)/(60 -C)) = 2ln(1.3) +ln(2.5) = ln(2.5·1.3²) = ln(4.225)

Taking antilogs, we have ...

(150 -C)/(60 -C) = 4.225

1 +90/(60 -C) = 4.225

C = 60 -90/3.225 ≈ 32.093 . . . . . grams of product in 20 minutes

In 20 minutes, about 32.1 grams of C are formed.
