The average of two numbers is 13, and their product is 133. Use the quadratic formula to find the numbers. What is the value of the larger number?

There are no local extrema since there isn't any x value that causes the first derivative to be equal to 0.

z = 5x + 3 y

Discover the function's first derivative.

By applying the Sum Rule, the derivative of 5 x + 3 y with respect to x is d d x [ 5 x ] + d /d x [ 3 y ].

d/d x [ 5 x] + d /d x [ 3 y]

Analyze d /d x [ 5 x ].

Tap to take other actions...

5 + d /d x [ 3 y]

Because 5 is independent of x, its derivative is 5 d d x [ x ] since 5 is constant with respect to x.

5 d/ d x [ x ] + d /d x [ 3 y]

The Power Rule, which asserts that d d x [ x n ] is n x n 1 where n = 1. 5 1 + d d x [ 3 y ] is a method of differentiation, says that you should differentiate.

Subtract 1 from 5 and multiply the result by 5 + d /d x [ 3 y ]

The Constant Rule can be used to differentiate.

Because 3 y is constant in relation to x, its derivative in relation to x is 0 (5 + 0).

Subtract 5 from 0 to get 5.

Since 5 is constant in relation to x, its derivative in relation to x is 0 (f " (x ) = 0).

By setting the derivative to 0, you can solve the problem and discover the function's local maximum and lowest values.

5 = 0

There are no local extrema since there isn't any x value that causes the first derivative to be equal to 0.

Answer:

To simplify this expression, we need to combine like terms. To do that, we need to combine terms that have the same variables raised to the same powers.

First, we will combine the terms in the first set of parentheses:

(4m²n² + 6m²n)

We see that the terms have the same variables, m and n, and the same powers, 2 and 1, respectively. We can combine these terms by adding their coefficients:

(4m²n² + 6m²n) = (4 + 6)m²n = 10m²n

Next, we will combine the terms in the second set of parentheses:

(8m²n^ - 7m²n² - 13m²n)

In this case, we see that the first two terms have the same variables and powers, so we can combine them by adding their coefficients:

(8m²n^ - 7m²n² - 13m²n) = (8 - 7)m²n^ - 13m²n = m²n^ - 13m²n

We can then combine the remaining term with the first term in the expression:

m²n^ - 13m²n + 10m²n = m²n^ + (-13 + 10)m²n = m²n^ - 3m²n

Finally, we will combine the terms in the third set of parentheses:

(14m²n - 2m^n² + 9m²n)

In this case, we see that the first two terms have the same variable and power for the m variable, but the powers of the n variable are different. Since we cannot combine these terms, we will need to leave them as is. We can, however, combine the remaining term with one of the other terms:

(14m²n - 2m^n² + 9m²n) = 14m²n - 2m^n² + (9 + (-14))m²n = 14m²n - 2m^n² - 5m²n

We can then combine this expression with the previous one:

14m²n - 2m^n² - 5m²n + m²n^ - 3m²n = (14 - 1)m²n - 2m^n² - (5 - 3)m²n = 13m²n - 2m^n² - 2m²n

Finally, we have simplified the expression as much as possible:

(4m²n² + 6m²n) - (8m²n^ - 7m²n² - 13m²n) - (14m²n - 2m^n² + 9m²n) = 13m²n - 2m^n² - 2m²n

Answer:

9/56

Step-by-step explanation:

Area of a rectangle = width x length

Area = (3/8) x (3/7) = 9/56

Mutiplying fractions is easy, just multiply the numerator, then multiply the denominator.

The point zero represents option (A) the location of the starting line

Here, -35 represents the starting location of a race car that is 35 yards behind the starting line.

Therefore, the location of the starting line = starting location of a race car that is 35 yards behind the starting line + 35

Substitute the values in the equation

The location of the starting line =  -35 + 35

Add the numbers

= 0

The ending location of a race car = 35

Thar is 35 yards in front of the starting line

Therefore, the zero represents the location of the starting line

On the graph, the graph equation has been drawn, crossing the y and x-axis points (0, 10) and (20, 0).

To calculate the slope m and the y-intercept, write the equation y = MX + b.

The slope and y-intercept can then be used to graph the equation (0, b).

The three primary forms of linear equations are point-slope, standard, and slope-intercept.

So, the equation is as follows:

8x+16y=160

Now,

The short sleeves are symbolized by an x.

y is a symbol for the long sleeves.

The equation must now be plotted as follows:

(Please see the graph below.)

As a result, the y and x-axis points (0, 10) and (20, 0) intersected by the equation.

Therefore, on the graph, the graph equation has been drawn, crossing the y and x-axis points (0, 10) and (20, 0).

Answer:

If Doug has $100,000 in a savings account that earns 13% interest per year and the interest is not compounded, then after four years he will earn $52,000 in interest. This is because 13% of $100,000 is $13,000, and since the interest is not compounded, this amount will remain constant for each year. Therefore, after four years Doug will earn a total of $13,000 + $13,000 + $13,000 + $13,000 = $52,000 in interest.

In general, if a savings account earns x% interest per year and the initial amount in the account is y dollars, then after n years the account will earn n * (x/100) * y dollars in interest. For example, if the interest rate is 13% and the initial amount is $100,000, then after four years the account will earn 4 * (13/100) * $100,000 = $52,000 in interest.

The combined area of the shaded triangles in figure one is 2ab. We have four congruent right triangles given, with legs a and b. The formula to calculate the area of a right triangle is (leg * leg) / 2. So the area of one of the triangles is ab/2. We have four of these triangles, so ab/2 * 4 = 2ab.

The area of the unshaded square in figure one can be represented as c^2. Since the side of the square is given as c, its area must be c^2 (calculate the area of a square by multiplying its side length by itself).

The combined area of the unshaded squares in figure 2 can be represented by a^2 + b^2. Again, we find the areas of each square by multiplying the side lengths togther: (a * a) + (b * b) = a^2 + b^2.

Finally the areas of the squares in figure one and figure two show that a^2 + b^2 = c^2. This is because the shaded triangles in figure one take up the same area as that of figure two. And since the total figure areas are the same, the unshaded parts of each figure must be equal to each other. Therefore, we have a^2 + b^2 = c^2. This is also known as the Pythagorean Theorem.

Angle K has  a value of 63 degrees.

Given,

The triangle KLM

Angle L = 4x + 7

Angle K = 6x - 9

Angle M = 118° (Exterior)

We have to find the value of angle K.

Here,

Angle M (Interior) = 180 - 118 = 62° (linear pair of angles)

Now,

Angle L + Angle K + Angle M = 180° (Sum of interior angles of a triangle)

Then,

4x + 7 + 6x - 9 + 62 = 180

10x - 2 + 62 = 180

10x  + 60 = 180

10x = 180 - 60

x = 120/10

x = 12

Now,

Angle K = 6x - 9  = 6 × 12 - 9 = 72 - 9 = 63

In the given question,

The paper will be shipped in small boxes and large boxes.

Each small box of paper weights 45 pounds.

Each large box of paper weights 75 pounds.

There were 3 more small boxes shipped than large boxes and the total weight of all boxes was 1455 pounds.

We have to write a system of equations that could be used to determine the number of small boxes shipped and the number of large boxes shipped.

We also have to define the variables that we use to write the system.

Let x be the number of small boxes.

Let y be the number of large boxes.

There were 3 more small boxes shipped than large boxes.

So x = y+3

Weight of x number of small boxes = 45x

Weight of y number of small boxes = 75y

Total weight of boxes = 1455

So; 45x+75y=1455

Now putting the value of x to this system of equation

45(y+3)+75y=1455

45y+135+75y=1455

120y+135=1455

Subtract 135 on both side, we get

120y=1320

Divide by 120 on both side, we get;
