An attic floor is shaped like a triangle with a height of n yd and a base of 6 yd.Which expression represents the area of the floor? 6n3nn + 63n2

Answer:

66

Explanation:

By the Thales theorem, if we have the following figure:

Then, the following equation applies:

So, in this case, we can formulate the following equation:

Then, solving for x, we get:

Therefore, the value of x is 66.

The lines that are not intersecting and perpendicular to each other, are not parallel to each other, and are not coplanar are called skew lines.

The four lines that are skew to line EF are AB, GB, CH, and DC.

The lines that are not intersecting and perpendicular to each other, are not parallel to each other, and are not coplanar are called skew lines.

We have,

A line EF on the given square figure.

We have the following lines on the given figure.

DG, CB, HA, FA, FG, GB, AB, EH, ED, DC,CH,

We see that,

FG, FA, EH, and ED are perpendicular and intersecting to line EF.

DG, CB, and HA are parallel to line EF.

So the remaining lines will be skew to line EF

i.e AB, GB, CH, and DC

Thus,

The four lines that are skew to line EF are AB, GB, CH, and DC.

The given expression is

y = (x²-7x)^5 (3x^5-5x)

To differentiate, we would apply the product rule which is expressed as

(fg)' = f'g + fg'

Let f = (x²-7x)^5 and g = (3x^5-5x)

f' = 5(2x - 7)(x²-7x)^4

g' = 15x^4 - 5

By applying the product rule, it becomes

y' = 5(2x - 7)(3x^5-5x)(x²-7x)^4 + (15x^4 - 5)(x²-7x)^5

The domain of the function is [1, ∞) and the range of the function is [0,∞).

Domain and range:

The domain and range of a function are  refers the set of all the inputs and outputs a function can give respectively.

Basically, domain takes all the possible input values from the set of real numbers whereas the range takes all the output values of the function.

Given,

Here we have the function

y = √x - 1

Now, here we need to find the domain and range of the function.

The given function is rewritten as,

√x - 1 > 0

Square both sides then we get,

x - 1 > 0

Add 1 on both sides then we get,

x > 1

Therefore, the domain is [1, ∞).

Similarly, let us consider, y ≥ 0

Therefore, the range is [0,∞).

The area of the smaller rectangle is 108 inches².

The area of a rectangle is calculated to determine the area occupied by the rectangle within its boundary. A rectangle's area (A) is the product of its length 'a' and width or breadth 'b'. As a result, the Area of the Rectangle = (a × b) square units.

Given the dimensions of the smaller rectangle:

Length = 12 inches

Width = x inches

Given the dimensions of the larger rectangle:

Length = 20 inches

Width = 15 inches

To find the value of x we use proportion,

[tex]\frac{12}{x} = \frac{20}{15}[/tex]

Cross-multiplying, we get

12 × 15 = 20x

x = 180/20 = 9

Hence, the width of the smaller rectangle is 9 inches.

Area of the smaller rectangle = length × width

                                                = 12 × 9

                                                = 108 inches²

Answer: f(3) = 0.84375

Step-by-step explanation:

f(3) is asking for the value of the function when x = 3, not multiplying f by 3. (f(x) is basically the output, y)

So we just plug in 3 for x and simplify (use PEMDAS)

f(3) = 2(0.75)^3

f(3) = 2(0.421875)

f(3) = 0.84375

Answer:

[tex]\frac{27}{32}[/tex]

Step-by-step explanation:

It may be a bit easier to represent 0.75 as a fraction, since we can use the following property of exponents: [tex](\frac{a}{b})^x = \frac{a^x}{b^x}[/tex]

We can represent 0.75 as: [tex]\frac{3}{4}[/tex]

And substituting this into the function we get: [tex]f(x)=2(\frac{3}{4})^x[/tex]

calculating the value when x=3, we get: [tex]f(3)=2(\frac{3}{4})^3[/tex]

using the property previously stated we get: [tex]f(3)=2(\frac{3^3}{4^3})[/tex]

Raising each value to the exponent we get: [tex]f(3)=2(\frac{27}{64})[/tex]

When we multiply by two, we can simplify by splitting up 64, into two factors: 2 and 32, to get: [tex]\frac{2*27}{32*2}[/tex]

From here it's easy to see that we can cancel out the values 2, to get: [tex]\frac{27}{32}[/tex]

The time taken by Town A to Town B will be 3 hours.

Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance traveled by time. The unit of speed in miles per hour.

Given that at 30 mph a trip from Town A to Town B takes 6 hours.

The time taken will be calculated as,

Total distance = 30 x 6 = 180 meters

Speed = 30 x 2 = 60 mph

The time,

T = 180 / 60= 3 hours

Therefore, the time taken by Town A to Town B will be 3 hours.

The value of x is 10 and the length of SU is 50.

Here SU is the line and T is the mid-point of the line

So from this we have

SU = ST + TU

ST = TU

SU = 2ST = 2TU

ST = 3x - 5 and TU = 2x + 5

As ST = TU

3x - 5 = 2x + 5

x = 10

SU = 2ST

     = 2( 3x - 5)

     = 2( 3 × 10 - 5)

     = 2( 30 - 5)

     = 2× 25

     = 50

Therefore the value of x is 10 and the length of SU is 50.
