Answer:

8 and 1/3

Step-by-step explanation:

First, let's understand the situation. There is a 25 oz juice that is to be split 3 ways. To determine the amount of jucie each person gets, we will take the total amount of juice and divide it by the number of kids, 3. When we do this, we get 25/3. Since this fraction can;t be simplified into a whole number, we will need to turn 25/3 into a mixed number. To do this, we need to know how many times 3 goes into 25. 3 goes into 25 8 times with a remainder of 1. This remainder is put over 3, giving us the final answer, 8 and 1/3.

Answer:

D

Step-by-step explanation:

The correct answer is D. −0.6; for every additional hour, the length of the icicle decreases by 0.6 inches.

The slope of a line represents the rate of change of one variable with respect to the other variable. In this case, the length of the icicle (y) is changing with respect to time (x). The slope of the line represents the change in the length of the icicle (y) for every additional hour (x).

Since the icicle is melting at a rate of 0.6 inches per hour, the length of the icicle decreases by 0.6 inches for every additional hour. The slope of the line representing this relationship is -0.6. This means that for every additional hour, the length of the icicle decreases by 0.6 inches.

A vector w that is orthogonal to both u and v is w = (-1,-1,-1) and a vector x which is orthogonal to u and lies in the same plane defined by u and v is x = (-1,2,1).

The vectors are

u = (1, 0, 1)

v = (0, 2, 2)

If the scalar product of two vectors is equal to zero, then the vectors are orthogonal.

If we let let w = (a, b, c)

Then (u, w) ≥ 0

1×a + 0×b + 1×c = 0

a + c = 0

Subtract c on both side, we get

a = -c

and (v, w) = 0

0×a + 2×b + 2×c = 0

2b + 2c = 0

2(b + c) = 0

b + c = 0

b = -c

Then w = (-c, -c, -c)

If c=1

Then the orthogonal vector

w = (-1,-1,-1)

Let x = (x, y, z)

x is now orthogonal to u.

That is (u, x) = 0

1×x + 0×y + 1×z = 0

x + z = 0

x = -z

u × v = [tex]\begin{vmatrix}\hat{i} & \hat{j} & \hat{k}\\ 1 & 0 & 1\\ 0 & 2& 2\end{vmatrix}[/tex]

u × v = [tex]\hat{i}[/tex](-2) - [tex]\hat{j}[/tex](2) + [tex]\hat{k}[/tex](2)

u × v = -2i-2j+2k

The given condition x lies on the plane u and v

(-2, -2, -2), x ≥ 0

-2x - 2y + 2z = 0

[x = -z]

2z - 2y + 2z = 0

Answer:

  y = 0.4·5^x

Step-by-step explanation:

You want an exponential function y = a·b^x that passes through the points (1, 2) and (3, 50).

The given point values give two equations in two unknowns when used in the given exponential form:

  y = a·b^x

  2 = a·b^1

  50 = a·b^3

Dividing the second equation by the first, we find b:

  50/2 = (ab^3)/(ab)

  25 = b^2 . . . . . simplify

  5 = b . . . . . . . . . square root

Then the value of 'a' can be found from the first equation:

  2 = a·5

  a = 2/5 = 0.4

Using these values of 'a' and 'b', we have the exponential function ...

  y = 0.4·5^x

2. $x-20%=x

3. >>>>>?

Step-by-step explanation:

A 20% discount means that you subtract 20% of the normal price.  Suppose the normal price is $100.  20% of this is $20.  Subtract this from $100 and you have the new price---$80.

Note that "subtracting 20%" is the same as multiplying by 0.8----the general formula is:

discount price = normal price * (1-d)   , where d is the decimal equivalent of the percentage discount.

From the example above:

discount price = normal price * (1-d) = 100(0.8)

to go the other way, simply rearrange the formula:

normal price = discount price / (1-d)

The greatest common divisor of two or more integers that are not all zero in mathematics is the biggest positive integer that divides each of the integers.

The biggest common factor is the factor that splits both numbers in half. To get the greatest common factor, first list each number's prime factors.

A set's greatest common factor (GCF) is the biggest factor that all of the numbers share. For example, the numbers 12, 20, and 24 all have two common factors: 2 and 4. The greatest is 4, hence the GCF of 12, 20, and 24 is 4. GCF is frequently used to locate common denominators.

As we have, two different terms as: 5x^3, –5x

Prime factorisation of 5x^3 = 5*x*x*x

While the prime factorisation of -5x = -1*5*x

There is a 68% chance that a repair claim will be between $40 and $1020.

The normal distribution is a continuous probability distribution that is symmetric around the mean, with mean and variance being the same. In this case, the mean is $530 and the standard deviation is $490. This means that the repair claims are normally distributed, with the majority of the claims being between $530-$490 and $530+$490. This gives us a range of $40-$1020.

The normal distribution is often used to describe random variables because it is the most common probability distribution. In this case, it implies that the repair claims are randomly distributed around the mean of $530. The standard deviation of $490 indicates that there is a 68% chance that a repair claim will be within one standard deviation of the mean. In this case, that means that there is a 68% chance that a repair claim will be between $40 and $1020.

The average rate of change of V with respect to r over the interval [85,110] is 0.76 meters cubed per year per centimetre of rainfall.

V(r) = 0.2r² − 20r + 600

The average rate of change of V with respect to r over the interval [85,110] can be calculated by finding the derivative of V(r) and evaluating it at the midpoint of the interval, then dividing the result by the length of the interval. The derivative of V(r) is:

dV/dr = 0.4r - 20

The midpoint of the interval [85,110] is (85 + 110)/2 = 97.5. Evaluating the derivative at the midpoint, we get the following:

dV/dr = 0.4 × 97.5 - 20 = 19.0

The length of the interval is 110 - 85 = 25, so the average rate of change is:

The average rate of change = (dV/dr)/(110 - 85) = 19.0/25 = 0.76

So, the average rate of change of V with respect to r over the interval [85,110] is 0.76 meters cubed per year per centimetre of rainfall.

Double integrals are a way to integrate over a two-dimensional area. In some cases, the integral of one variable function, a double integral, is defined as a limit of a Riemann sum.

Double integrals are used to calculate the area of a region, the volume under the surface, and the average value of a function of two variables over a rectangular region. In a double integral, the outer limits must be constant, but the inner limits can depend on the outer variable. This means, we must put y as the inner integration variables, as was done in the second way of computing
