Answer:

6 hours

Step-by-step explanation:

[tex]\frac{1}{6}[/tex] of Total battery life = [tex]\frac{1}{6} * 3600 = 600[/tex]milliamps

Assuming the battery takes 100 Milliamps per hour,

Time = Battery Capacity / Current hours

Time = 600 / 100 Mah = 6H

We can use the principle of inclusion-exclusion to find n(U), which states that for two sets A and B:

n(A union B) = n(A) + n(B) - n(A intersection B)

We can apply this to three sets r, s, and their complements r' and s':

n(U) = n(r union s)

= n(r) + n(s) - n(r intersection s)

= [n(r intersection s') + n(r intersection s)] + [n(s intersection r') + n(s intersection r)] - n(r intersection s)

= [(4 + n(r' intersection s)) + (n(r intersection s') + 7)] - 4

= n(r' intersection s) + n(r intersection s') + 3

= 7 + 3 + 3

= 13

Therefore, n(U) = 13.

Answer:

Step-by-step explanation:

x+y=17

x-y = 7

From equation 2, x = 7 + y

put this in equation 1.

(7+y) + y = 17

7+2y = 17

2y = 10

y = 5.

We said that x = 7+y

thus, x = 7 + 5

x = 12.

2x+2y=36

2(x+y) = 36

Thus, x + y = 18.

x+y = 18

x-y=6 using elimination (literally simplifying this)

2x = 24 (y-y=0. ELIMINATED!)

x = 12

When x = 12,

x+y=18

12+y=18

y=6.

3x = y

x + y = 20

From 1, y = 3x.

x + (3x) = 20

4x = 20

x = 5.

when x = 5,

y = 3x

y = 3(5)

y = 15.

x+y = -4

xy = -21

from 1, x = -4-y

=> y(-4-y)= -21

-y²-4y = -21

Therefore,

y² + 4y -21 = 0

y= 3 or -7.

When y = 3,

x + 3 = -4

x= -7.

When y = -7,

x + (-7) = -4

x-7=-4

x = 3.

Answer:

Step-by-step explanation:

Explain the question.

After expanding the polynomial (5x² + x - 7)(x - 4) - (2x³ + 5x² - 6), b = -24

A polynomial is a mathematical expression in which the power of the unknown is greater than or equal to 2.

Since we have the polynomial (5x² + x - 7)(x - 4) - (2x³ + 5x² - 6) and we want it expressed as a polynomial in the form ax³ + bx² + cx + d, to find the value of b, we proceeda s follows.

(5x² + x - 7)(x - 4) - (2x³ + 5x² - 6)

Expanding the brackets, we have that

(5x² + x - 7)(x - 4) - (2x³ +5x² - 6) = 5x³ - 20x² + x² - 4x - 7x + 28 - (2x³ + 5x² - 6)

= 5x³ - 20x² + x² - 4x - 7x + 28 - 2x³ - 5x² + 6

Collecting like terms, we have

= 5x³ - 2x³ - 20x²- 5x² + x² - 4x - 7x + 28 + 6

= 3x³ - 24x² - 11x + 34

So, comparing 3x³ - 24x² - 11x + 34 with ax³ + bx² + cx + d, we have that

The solution of the system of equations from the graph is x = 2.

The point of intersection formula is used to determine where two lines meet, or the point at which they intersect. In Euclidean geometry, the intersection of two lines can be either an empty set, a point, or a line. Two lines must meet certain requirements in order to intersect, including being in the same plane and not being skew lines. The intersection of these lines may be determined using the intersection formula.

The solution of the system of equations can be determined from the graph by determining the point of intersection between the two lines.

From the graph we observe that the point of intersection of the two lines is at (0, 2).

Hence, the solution of the system of equations is x = 2.

The caterpillar touches 15 points with two integer coordinates, including the start point (-3, -4) and the end point (25, 38).

What is co-ordinate geometry ?

Coordinate geometry is a branch of mathematics that deals with the study of geometry using the principles of algebra. In coordinate geometry, geometric figures are represented using algebraic equations and analyzed using techniques from algebra and calculus.

The caterpillar moves from (-3, -4) to (25, 38) in a straight line. We can find the equation of the line passing through these two points using the slope-intercept form of the equation of a line:

y - (-4) = (38 - (-4))/(25 - (-3)) * (x - (-3))

y + 4 = 42/28 * (x + 3)

y = 3/2 * x + 19

The caterpillar touches a point with two integer coordinates whenever x and y are both integers. To find these points, we can substitute integer values for x and solve for y. Since the slope of the line is 3/2, every time x increases by 2, y increases by 3.

Starting from x = -3, we can list the integer values of x that the caterpillar touches:

-3, -1, 1, 3, 5, ..., 25

For each value of x, we can compute the corresponding value of y using the equation of the line:

y = 3/2 * x + 1

For example, when x = -3, y = 3/2 * (-3) + 19 = 14.5, which is not an integer. When x = -1, y = 3/2 * (-1) + 19 = 17.5, which is also not an integer. However, when x = 1, y = 3/2 * 1 + 19 = 20, which is an integer. Similarly, we can find the integer values of y for all the other values of x.

Therefore, the caterpillar touches 15 points with two integer coordinates, including the start point (-3, -4) and the end point (25, 38).

The upper bound of the volume of water left in the fish tank is 60 liters.

33.81 fluid ounces make up one litre (US).

One litre of water would fill about one-fourth of a gallon water bottle. Also, you should be aware that there are two different kinds of ounces used globally to measure water volume: (1 litre = 33.814 US ounces).

The maximum allowable mistake can be added to the actual value to determine the upper bound of the amount of water still in the fish tank.

The maximum error for 90 litres, rounded to one significant figure, is half of the value of the last significant figure, or 5. Hence, the actual value of 90 litres might be either 85 or 95.

The largest potential inaccuracy for 30 litres, rounded to one significant figure, is likewise 5. Hence, the actual value of 30 litres might be 25 or 35.

We subtract the lower bound of the withdrawn volume from the higher bound of the original volume to determine the upper bound of the volume of water still present in the tank.

The upper bound of the volume of water left in the fish tank can be found by adding the half of the absolute uncertainty to the measured value of 60 liters (90 - 30):

Upper bound = 60 + 0.5 x 1 = 60.5 liters (rounded to 1 significant figure)

We can use the Pythagorean theorem to find the length of the diagonal of the rectangle. The Pythagorean theorem states that in a right triangle with legs of length a and b and hypotenuse of length c, we have:

a^2 + b^2 = c^2

In this case, the rectangle has dimensions of 14 centimeters by 48 centimeters, so we can let the length and width of the rectangle be the legs of a right triangle, and the diagonal be the hypotenuse. Then:

a = 14 cm b = 48 cm c = ?

We can plug these values into the Pythagorean theorem and solve for c:

14^2 + 48^2 = c^2 196 + 2304 = c^2 2500 = c^2 c = sqrt(2500) c = 50

Therefore, the length of the diagonal of the rectangle is 50 centimeters.

Answer:

50 cm

Step-by-step explanation:

the equation is d=sqrt(w^2+l^2)

so you get sqrt(14^2+48^2) which equals 50.

Answer: Let's use the following system of equations to represent the given information:

h + c = 131    (the total number of burgers sold is 131)

2.5h + 2.75c = 342    (the total value of the burgers sold is $342)

where h represents the number of hamburgers sold and c represents the number of cheeseburgers sold.

We can use the first equation to solve for one of the variables in terms of the other:

h + c = 131

h = 131 - c

Substituting this into the second equation, we can solve for c:

2.5h + 2.75c = 342

2.5(131-c) + 2.75c = 342

327.5 - 2.5c + 2.75c = 342

0.25c = 14.5

c = 58

So, 58 cheeseburgers were sold. We can use the first equation to find the number of hamburgers sold:

h + c = 131

h + 58 = 131

h = 73

Therefore, 73 hamburgers were sold.

`C(p,k) * C(n-p,k)`

a. Proof: We will apply the same method we used in formula (1) in our class notes on this question. For this purpose, we choose a set containing `n + 1` elements. It contains all elements of the set of `n` elements and another element `y` that has not been included in the set of `n` elements.Let the number of sets of `n` elements that contain `k` particular elements `a` be `P(n, k)`. To count the number of sets of `n + 1` elements that contain `k` elements, we use the concept of permutations with repetition, such as -{n + 1} can be placed in any of the `k` places of the k-element subsets of `{1, 2,...,n}`, or it can be one of the remaining `n-k+1` elements in each of the `P(n,k)` sets that contain `k` elements.Let us use `A` to denote the set of sets of `n` elements that do not contain the element `y` and `B` to denote the set of sets of `n` elements that contain the element `y`. Then, `P(n+1,k)=|A|+|B|=P(n,k)+(n−k+1)P(n,k−1)`.b. Proof: To count the number of `k` element subsets from a set of `n` elements, we use `C(n, k)`.Let us consider two sets, `A` and `B`, where `|A|=n-k` and `|B|=p-k`. We want to choose `k` elements from these two sets such that the number of subsets we get from `A` is `x` and the number of subsets we get from `B` is `y`. In the set `A`, we select `x` elements by choosing `k-x` elements from the remaining `n-k` elements. Similarly, in the set `B`, we select `y` elements by choosing `k-y` elements from the remaining `p-k` elements.Thus, the total number of ways of choosing `k` elements from `A` and `B` is given by `C(n-k, x) * C(p-k, y)`. The total number of ways of choosing `k` elements from `n` elements is given by `C(n, k)`. Therefore, the total number of ways of choosing `k` elements from `n` elements such that `x` elements are chosen from `A` and `y` elements are chosen from `B` is `C(n-k, x) * C(p-k, y) * C(n, k)`.To get the total number of ways of choosing `k` elements from `n` elements such that `k` elements are chosen from `A` and `p-k` elements are chosen from `B`, we must sum over all possible values of `x` and `y`. Thus, the total number of ways of choosing `k` elements from `n` elements such that `k` elements are chosen from `A` and `p-k` elements are chosen from `B` is given by: `C(p,k) * C(n-p,k)`  which is the required result.

Draw an imaginary line from F to S. We then break this into 2 parts:

1. Evaluate the area of triangle SFN

The base of the triangle is FS, who has length 9. The height is the vertical line that passes through point N and FS, and that line has length 6. The area would then be 9*6/2=27.

2. Evaluate the area of rectangle SCWF

WC has length 9. FW has length 2. The area would then be 9*2=18.

The resulting constant is 2/5 when (2-4/3) is subtracted from (-3/5 plus 5/3).

Mathematical subtraction includes calculating the difference between two numbers. It is the inverse of addition and is denoted by the symbol "-". When we subtract one number from another, we are essentially finding out how much smaller the second number is than the first number.

We can simplify the expressions inside the parentheses first:

2 - 4/3 = 6/3 - 4/3 = 2/3

-3/5 + 5/3 = -9/15 + 25/15 = 16/15

So the expression (-3/5 + 5/3) - (2 - 4/3) becomes:

(16/15) - (2/3)

To subtract these fractions, we need to find a common denominator, which is the least common multiple of 15 and 3, which is 15. Then we can rewrite both fractions with this denominator:

(16/15) - (2/3) = (16/15) - (10/15)

Now we can subtract the numerators and keep the denominator:

(16/15) - (10/15) = 6/15 = 2/5

Therefore, the resulting constant is 2/5.
