Consider Carmen’s plans.

Parallel lines k and l are crossed by transversal t. Line m crosses lines t, k, and l. The angles formed by lines k, t, and m, clockwise from top left are 2, 1, blank, blank, blank (6 x + 5) degrees; formed by lines l and t are blank, (7x minus 4) degrees, blank, blank; formed by lines l and m are 48 degrees, blank, blank, blank.

Carmen used her knowledge of angle relationships to find the value of x in the diagram.

What is the value of x?
x = 5
x = 9
x = 13
x = 16
the answer is 9

Answer:

1

Step-by-step explanation:

because parentheses go first so 2 x 3 = 6 minus 1 = 5 minus 4 = 1

I am going to assume that leg a:

  ⇒ is the horizontal distance between the house and the gas station

     ⇒ Distance for leg a: 6 miles

I am also going to assume that leg b

  ⇒ is the vertical distance between the house and gas station

     ⇒ Distance for leg b: 5 miles

Thus using the Pythagorean theorem: [tex]a^2+b^2=c^2[/tex]

   ⇒ (look at diagram attached for further explanation)

   [tex]a^2+b^2=c^2\\\\6^2+5^2=c^2\\c=\sqrt{6^2+5^2} \\c=\sqrt{61} =7.81[/tex]

Answer: 7.81

Answer:

49.7359 units²

Step-by-step explanation:

Area = πr²

Circumference = 2πr

2πr = 25

πr = 12.5

r = 12.5 / π = 3.97887

π(3.97887)² = 49.7359 units²

Answer:

12

Step-by-step explanation:

there are 12

between 23 and 35

Answer:

$111222.02

Step-by-step explanation:

This year = Last year * (100%-9%)

This year = 122222 * 91% = 111222.02

It's around 1 to 3

So

From 35 it's 1,2,3

From 5500 samples of 35

Now

If 1 comes from each

If 2

If 3

The domain of the inverse of the function f(x) = 5e^x + 3 is found being all real numbers > 3. Or, we can write this symbolically as: D( f^(-1)(x)) = (3,∞)

Domain is the set of values for which the given function is defined.

Range is the set of all values which the given function can output.

Suppose that the given function is

[tex]f:X\rightarrow Y[/tex]

Then, if function 'f' is one-to-one and onto function (a needed condition for inverses to exist), then, the inverse of the considered function is

[tex]f^{-1}: Y \rightarrow X[/tex]

such that:

[tex]\forall \: x \in X : f(x) \in Y, \exists \: y \in Y : f^{-1}(y) \in X[/tex]

(and vice versa).

It simply means, inverse of 'f' is undo operator, that takes back the effect of 'f'

The domain of the inverse of a function (if it exists) is the range of the function it is inverse of. Similarly range of the inverse of that considered function is the domain of that considered function.

The function given is:

[tex]f(x) = 5e^x + 3[/tex]

The domain of the inverse of this function is this function's range.

Assuming only real values are allowed, for any real number x, we have:

[tex]e^x > 0[/tex]

And therefore, we get:

[tex]5e^x > 0 \: \forall x \in \mathbb R\\5e^x + 3 > 3 \: \forall x \in \mathbb R\\[/tex]

Also, since the function [tex]f(x) = 5e^x + 3[/tex] is strictly monotonically increasing and continuous, it touches all the values as its output from any real number > 3 till any finitely large number.

Thus, its range is (3, ∞) (it is an interval consisting of all the real numbers > 3)

This is the domain of its inverse function.

Thus, the domain of the inverse of the function f(x) = 5e^x + 3 is found being set of all real numbers > 3. Or, we can write this symbolically as: D( f^(-1)(x)) = (3,∞)

Answer:

0.315  to nearest thousandth.

Step-by-step explanation:

7e^3x − 4 = 14

7e3x  = 18

e^3x = 18/7

3x = ln(18/7)

x = ln(18/7) / 3

The volume of the cylinder is 471.43 cm³.

The volume of the cone is 157.14 cm³.

The volume of the sphere is  523.81 cm³.

The shape that would hold the most volume is the sphere.

A cylinder is a three-dimensional object. It is a prism with a circular base.

Volume of a cylinder = πr²h

Where:

π = 22/7

r = radius

22/7 x 5² x 6 = 471.43 cm³

Volume of a cone = 1/3 x volume of a cylinder

1/3 x  471.43 cm³ = 157.14 cm³

What is the volume of a sphere?

Volume of a sphere = 4/3 x pi x r³

4/3 x 5³ x 22/7 = 523.81 cm³

Answer:

x = 27

Step-by-step explanation:

because the angles are on a line that means they add up to 180

18 + x + 5x = 180

then combine like terms

18 + 6x = 180

then you subtract 18 from both sides

6x = 162

lastly divide both sides by 6

x = 27

Step-by-step explanation:

the first : e.g. a trapezoid

only 2 lines are parallel, but still it is a closed object with 4 vertexes and therefore 360° sum of internal angles. and 2 of the angles are smaller than 90°, and 2 are larger than 90°.

the second : a parallelogram, with all 4 sides having the same length. a square that is pushed e.g. on the top while the bottom stays.

the third : a rectangle. perpendicular means intersecting at 90°. but not a square. length and width must be different.

that's it, really. what was so confusing for you ?

The surface area of the barn is 2040 square feet.

A rectangle is a plane shape with four sides and four right angles.

Analysis:

The barn is composed of:

Two straight  long rectangles with dimensions = 10ft x 40ft

Two slant rectangles with dimensions = 10.6ft x 40ft

Two short rectangles with dimensions = 10ft x 14ft

Two triangles, height 8ft and base 14feet

The surface area of barn = 2(10x40) + 2(10.6 x 40) + 2(1/2 x 14 x 8) + 2(10 x 40) = 800 + 848 + 112 + 280 = 2040 square feet

In conclusion, the surface area of the barn is 2040 square feet.

Answer:

x = -1/2.

Step-by-step explanation:

x^2 - 4 = (x - 2)(x + 2)  so if we multiply each term by x^2 -4 we get:

2 - 1(x - 2) = 3(x + 2)

2 - x + 2 = 3x + 6

2 + 2 - 6 = 3x + x

4x = -2

x = -1/2.

Answer:

[tex]-\frac{1}{2}[/tex]

Step-by-step explanation:

1. Multiply both sides of the equation by the LCM (x - 2)(x + 2):

[tex]\frac{2}{x^{2} -4} (x-2)(x+2)[/tex]

factor x² - 4 by rewriting it as x² - 2²

x² - 2² = (x + 2)(x - 2)

now we have;

[tex]\frac{2}{(x+2)(x-2)} (x-2)(x+2)[/tex]

cancel the common factors (x - 2)(x + 2)

= 2

-------------------------------

[tex]\frac{-1}{x+2} (x-2)(x+2)[/tex]

cross cancel the common factor (x + 2)

[tex]\frac{-1}{x-2}=-(x-2)=-x+2[/tex]

-------------------------------

[tex]\frac{3}{x-2} (x-2)(x+2)[/tex]

cross cancel the common factor (x - 2)

3(x + 2)

distribute the 3

3x + 6

-------------------------------

combining all new values, we have;

2 + (-x) + 2 = 3x + 6

-x + 4 = 3x + 6

2. Isolate x:

-x + 4-4 = 3x + 6-4

-x = 3x + 2

-x-3x = 3x-3x + 2

-4x = 2

-4x/-4 = 2/-4

x = [tex]-\frac{1}{2}[/tex]
