Answer:

f(-4) = 15

Step-by-step explanation:

A function is notated as f(x), because the x is the value you are putting in. For example. In f(x) = x + 5, the value you are putting in is x, and the output would be x + 5.

So in this case, we have f(x) = -7x-13. We are to figure out f(-4), so we can simply put in -4 as the x-value;

-7(-4) - 13

28 - 13

15

And so the value of f(-4) = 15

The expanded form of the given expression is x^2 - 64.

The distributive property states that for any two numbers a and b, a(b+c) = ab + ac. This means that you can multiply a number by the sum of two numbers and get the same result as when you multiply that number by each of the two numbers separately and then add the two products together.

To expand the given expression, we need to use the distributive property. The distributive property states that a(b + c) = ab + ac. Applying this property to the given expression, we get:

(x + 8)(x - 8) = x(x - 8) + 8(x - 8)

Next, we need to distribute the x and 8 to the terms inside the parentheses:

x(x - 8) + 8(x - 8) = x^2 - 8x + 8x - 64

Finally, we can simplify the expression by combining like terms:

x^2 - 8x + 8x - 64 = x^2 - 64

The simplified answer is (5x)/(x^(2)-49)-(6)/(x+7) = -(x - 42)/((x + 7)(x - 7)).

To subtract and simplify the given expression, we need to find a common denominator and combine the numerators. The common denominator in this case will be (x^2 - 49), which can be factored into (x + 7)(x - 7).

So, the expression becomes:

(5x)/((x + 7)(x - 7)) - (6)/(x + 7)

To get a common denominator, we need to multiply the second term by (x - 7)/(x - 7):

(5x)/((x + 7)(x - 7)) - (6(x - 7))/((x + 7)(x - 7))

Now we can combine the numerators:

(5x - 6(x - 7))/((x + 7)(x - 7))

Simplifying the numerator gives us:

(-x + 42)/((x + 7)(x - 7))

And finally, we can simplify the expression by factoring out a -1 from the numerator:

-1(x - 42)/((x + 7)(x - 7))

So the final answer is:

-(x - 42)/((x + 7)(x - 7))

Answer:

A. y = 52x

Step-by-step explanation:

The equation is set up in slope-intercept form y = mx + b

m = the slope

b = y-intercept

Slope = rise/run or (y2 - y1) / (x2 - x1)

Pick 2 points (0,0) (4, 208)

We see the y increase by 208 and the x increase by 4, so the slope is

m = 208/4 = 52

Y-intercept is located at (0,0)

So, our equation is y = 52x

The answer is option A

One way to label the tick marks on the number lines is to use whole numbers for the longer tick marks and decimals for the shorter tick marks.

For example, on the first number line, you could label the longer tick marks as 0, 1, 2, 3, 4, and 5, and the shorter tick marks as 0.1, 0.2, 0.3, etc.

This fits with the structure of the base-ten system because each whole number is ten times greater than the corresponding decimal.

Another way to label the tick marks is to use fractions for the shorter tick marks. For example, on the second number line, you could label the longer tick marks as 0, 1, 2, 3, 4, and 5, and the shorter tick marks as 1/10, 2/10, 3/10, etc.

This also fits with the structure of the base-ten system because each fraction is one-tenth of the corresponding whole number.

Both of these labeling methods are accurate and fit with the structure of the base-ten system, so either one would be an appropriate way to label the tick marks on the number lines.

In the first production method, the company produces approximately 4,996 books.

Let's represent the number of books produced as x.

Total cost of method 1 = One-time fixed cost + Variable cost * Number of books produced

= $82,363 + $9.25x

Total cost of method 2 = One-time fixed cost + Variable cost * Number of books produced

= $21,162 + $21.50x

Setting the two equations equal to each other, we get:

$82,363 + $9.25x = $21,162 + $21.50x

Simplifying this equation, we get:

$61,201 = $12.25x

Dividing both sides by $12.25, we get:

x = 4,995.92

This means that the costs from the two methods will be the same when the company produces approximately 4,996 books.

The scale factor of dilation is 0.075 and the coordinates of F" are (0.9, 0.375)

The label of the triangle is added as an attachment

From the complete question, we have

DE = 12 units

Then, we have

D"E" = 0.9 units

Using the above as a guide, we have the following:

Scale factor = D"E"/DE

Scale factor = 0.9/12

Scale factor = 0.075

So, the scale factor of dilation is 0.075

This is calculated as

F = Scale factor * F

So, we have

F = 0.075 * (12, 5)

F = (0.9, 0.375)

The sine, cosine and tangent are calculated as

sin(D") = EF/DF

cos(D") = DE/DF

tan(D") = EF/DE

So, we have

sin(D") = 0.375/1 = 0.375

cos(D") = 0.9/1 = 0.9

tan(D") = 0.375/0.9 = 0.416

The value of fy(1,1) is 5.5 with one decimal digit on the right side of the decimal point.

To find the value of fy(1,1), we need to first find the partial derivative of f(x,y) with respect to y. This is done by treating x as a constant and taking the derivative with respect to y.

The partial derivative of f(x,y) with respect to y is:
fy(x,y) = (1/2)(4x2 - 2y + 7x4y5)-1/2 (-2 + 35x4y4)

Now we can plug in the values of x=1 and y=1 into the partial derivative to find the value of fy(1,1):
fy(1,1) = (1/2)(4(1)2 - 2(1) + 7(1)4(1)5)-1/2 (-2 + 35(1)4(1)4)
fy(1,1) = (1/2)(4 - 2 + 7)-1/2 (-2 + 35)
fy(1,1) = (1/2)(9)-1/2 (33)
fy(1,1) = (1/2)(1/3)(33)
fy(1,1) = 5.5

To find the height of the plane, we need to use trigonometry. Let's call the height of the plane "h". We can use the given angle of 57° and the opposite side (height) to the angle to find the adjacent side (distance traveled east) using the tangent function:

tan(57°) = h / distance traveled east

We can rearrange this equation to solve for h:

h = distance traveled east x tan(57°)

To find the distance traveled east, we need to use the given distance of 322 miles and the direction traveled. Since the plane is traveling at a 57° angle northeast, we can split this into two right triangles, one facing northeast and the other facing southeast, as shown below:

N

|

|

|\ 57°

|

\

The distance traveled east is the adjacent side of the southeast-facing right triangle, which can be found using the cosine function:

cos(57°) = distance traveled east / 322

We can rearrange this equation to solve for the distance traveled east:

distance traveled east = 322 x cos(57°)

Now we can plug in this value for the distance traveled east into the equation for the height of the plane:

h = distance traveled east x tan(57°)

h = (322 x cos(57°)) x tan(57°)

Using a calculator, we can evaluate this expression to find:

h ≈ 389.4 miles

Therefore, the height of the plane to the nearest mile is 389 miles.

A basis of the subspace of R4 defined by the equation 3x1​−9x2​+2x3​−3x4​=0 can be found by solving the equation for one of the variables in terms of the others and then writing the general solution as a linear combination of vectors.

First, solve the equation for x1 in terms of the other variables:

3x1 = 9x2 - 2x3 + 3x4

x1 = 3x2 - (2/3)x3 + x4

Next, write the general solution as a linear combination of vectors:

(x1, x2, x3, x4) = (3x2 - (2/3)x3 + x4, x2, x3, x4)

= x2(3, 1, 0, 0) + x3(-2/3, 0, 1, 0) + x4(1, 0, 0, 1)
