Answer:

A) Replace L with the length of the skid mark:

Speed = √(20(208))

Speed= √(4160)

Speed = 64.5 miles per hour

B) set the equation to the speed and solve for L:

Divide both sides by 20:

L = 110.5 feet

Answer:

x=8

AC=148

Step-by-step explanation:

Okay so if B is the midpoint of AC, that basically means that it's the halfway point. If B is exactly halfway between A and C, that means that the distance between A and B, and the distance between B and C is the same. In other words: AB=BC

Knowing that AB=BC, we can sub the values given by the question:

AB = BC

9x+2 = 5x+34

9x-5x = 34-2

4x = 32

x = 8

Now that we know the value of x, we can find AC, since AC=AB+BC

AC = AB + BC

= 9x+2 + 5x+34

= 14x+36

= 14(8)+36

=112+36

=148

Transformation involves moving a segment away from its original location.

The length of A'B' is 2cm

The length of AB is given as:

\(AB = 2cm\)

From the complete question, we understand that AB was translated to A'B'

Translation is a rigid transformation.

This means that it does not alter the length of the segment that is being translated.

So, the length of A'B' is represented as:

\(A'B' = AB\)

Substitute 2cm for AB

\(A'B' =2cm\)

Hence, the length of A'B' is 2cm

Mathematics is a discipline that has a long and rich history. It has evolved over time from simple counting and measuring to a broad and complex subject that is used in many fields. The development of mathematics has been driven by the need to solve practical problems, as well as the desire to understand the underlying patterns and structures of the world around us.

Early forms of mathematics, such as counting and measuring, were developed by ancient civilizations to solve practical problems such as trade, construction, and agriculture. These early forms of mathematics were based on empirical observations and were often tied to the physical world.

As mathematics developed, it began to include more abstract concepts such as numbers, geometry, and algebra. These abstract concepts allowed for the development of more complex mathematical techniques and the ability to solve a wider range of problems.

Today, mathematics is used in a wide range of fields including science, engineering, economics, and even art. It is an essential tool for understanding and solving problems in the world around us.

Explanation.

Rewrite. 3 x − 7 = 0 + 0 + 3 ( x + 1 )

Simplify by adding zeros. 3 x − 7 = 3 ( x + 1 )

Apply the distributive property. 3 x − 7 = 3 x + 3 ⋅ 1

Multiply 3 by 1 . 3 x − 7 = 3 x + 3

Subtract 3 x 3x from both sides of the equation. 3 x − 7 − 3 x = 3

Subtract 3 x 3x from 3 x 3x. 0 − 7 = 3 0-7=3

Subtract 7 7 from 0 0. − 7 = 3

Since − 7 ≠ 3 , there are no solutions.

Answer:  r = (2π/2)1/2 = 1 cm and h = 2 cm.

Step-by-step explanation:

The radius of the closed right circular cylindrical can of smallest surface area whose volume is 2π cm3 is 1 cm and the height is 2 cm. This can be computed by using the formula for the volume of a right circular cylinder, V = πr2h, and solving for the radius. The equation becomes r = (V/πh)1/2. When plugging in the given values, we find that r = (2π/2)1/2 = 1 cm and h = 2 cm.

The coordinate of point R after the rotation is determined as = ( - 4, 7).

option A.

A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction.

You can turn a figure 90°, a quarter turn, either clockwise or counterclockwise. When you spin the figure exactly halfway, you have rotated it 180°. Turning it all the way around rotates the figure 360°.

When a figure is rotated 180 degrees, each point of the figure is moved to a new position that is exactly opposite its original position with respect to a fixed center of rotation.

The initial coordinate of point R = ( 4, 7),

The new coordinate of point R after the rotation = ( - 4, 7)

The values of the other trigonometric functions for the given values of sin(Ф) and cos(Ф) are as follows, cos(Ф) = -5/4, sec(Ф) = -4/5, tan(Ф) = 16/25, cot(Ф) = 25/16.

To find the values of the other trigonometric functions of Ф, we can use the given information of sin(Ф) and cos(Ф).

We know that sin(Ф) = -4/5 and cos(Ф) = -5/4.

Recall that cos(Ф) is the reciprocal of sin(Ф), so we can determine cos(Ф) by finding the reciprocal of sin(Ф):

cos(Ф) = 1/sin(Ф) = 1/(-4/5) = -5/4

Similarly, we can find sec(Ф) by taking the reciprocal of cos(Ф):

sec(Ф) = 1/cos(Ф) = 1/(-5/4) = -4/5

To find tan(Ф), we can use the identities tan(Ф) = sin(Ф)/cos(Ф):

tan(Ф) = sin(Ф)/cos(Ф) = (-4/5)/(-5/4) = 16/25

Next, we can find cot(Ф) by taking the reciprocal of tan(Ф):

cot(Ф) = 1/tan(Ф) = 1/(16/25) = 25/16

Finally, we can find sec(Ф) by taking the reciprocal of csc(Ф):

cot(Ф) = 1/csc(Ф) = 1/(-5/4) = -4/5

Therefore, the values of the other trigonometric functions for the given values of sin(Ф) and cos(Ф) are as follows:

cos(Ф) = -5/4

sec(Ф) = -4/5

tan(Ф) = 16/25

cot(Ф) = 25/16

Answer:

geometric, with a common ratio of 1/2

Step-by-step explanation:

The sequence is geometric because you get successive trems by multiplying the previous term by a certain constant, the 'common ratio'. (If you got each successive term by adding or subtracting  the same constant number each time, that would be an arithmetic sequence.)

In this case, it looks like you get each successive term when you multiply the previous term by 1/2.

Thus, the common ratio is 1/2.

\( \Large{\boxed{\sf \dfrac{1 + 2i}{3 - 4i} + \dfrac{2 - i}{5i } = - \dfrac{2}{5}}} \)

\( \\ \)

Given sum:

\( \sf \: \dfrac{1+2i}{3-4i} + \dfrac{2-i}{5i}\)

\( \\ \)

We can simplify the sum only if the denominators of the two fractions are the same. Since they are different, we have to multiply the numerator and the denominator of each fraction by the denominator of the other one.

\( \sf \: \dfrac{1+2i}{3-4i} + \dfrac{2-i}{5i} = \dfrac{5i(1 + 2i)}{5i(3 - 4i)} + \dfrac{(3 - 4i)(2 - i)}{(3 - 4i)5i} \\ \\ \\ \sf \: = \dfrac{5i + 10 {i}^{2} }{15i - 20 {i}^{2} } + \dfrac{6 - 3i - 8i + 4 {i}^{2} }{15i - 20 {i}^{2} } \)

\( \\ \)

Replace i² with -1:

\( \sf \dfrac{5i + 10 {i}^{2} }{15i - 20 {i}^{2} } + \dfrac{6 - 3i - 8i + 4 {i}^{2} }{15i - 20 {i}^{2} } \: \\ \\ \\ \\ \sf \: = \dfrac{5i + 10( - 1)}{15i - 20( - 1)} + \dfrac{ 6 - 11i + 4( - 1)}{15i - 20( - 1)} \\ \\ \\ \\ \sf = \dfrac{5i - 10}{20 + 15i} + \dfrac{2 - 11i}{20 + 15i} \)

\( \\ \)

Simplify the expression:

\( \sf = \dfrac{5i - 10}{20 + 15i} + \dfrac{2 - 11i}{20 + 15i} \\ \\ \\ \\ \sf \: = \dfrac{5i - 10 + 2 - 11i}{ 20 + 15i} = \sf \dfrac{ - 8 - 6i}{20 + 15i}\)

\( \\ \)

To write our solution in the x + iy form, also known as the algebraic form, we have to understand what the conjugate of a complex number is.

\( \textsf{Let z be our complex number, and} \: \overline{\sf z} \: \textsf{its conjugate.} \)

\( \\ \)

The conjugate of z, \( \overline{ \sf z}, \) is the complex number formed of the same real part as z but of the opposite imaginary part.

Since x is the real part of z, and y is its imaginary part, this can be expressed as:

\( \sf If \: z = x + iy \:, then \: \overline{ \sf z} = x - iy \)

\( \\ \)

Now, we have to multiple both the denominator and the numerator of our fraction by the conjugate of its denominator:

\(\sf \dfrac{ - 8 - 6i}{20 + 15i} = \dfrac{( - 8 - 6i)( \overbrace{20 - 15i}^{ \overline{z}}) }{ (20 + 15i)( \underbrace{20 - 15i}_{ \overline{z}}) } \\ \\ \\ \sf = \dfrac{ - 160 + 120i - 120i + 90 {i}^{2} }{400 - 300i + 300i - 225 {i}^{2} } \\ \\ \\ \sf = \dfrac{ - 160 + 90 {i}^{2} }{400 - 225 {i}^{2} }\)

\( \\ \)

One more time, substitute -1 for i²:

\( \sf \: \dfrac{ - 160+ 90 {i}^{2} }{400 - 225 {i}^{2} } \: = \dfrac{ - 160 + 90( - 1)}{400 - 225( - 1)} \\ \\ \\ \sf = \boxed{\sf - \dfrac{ 250}{625}} \)

\( \\ \)

Finally, let's simplify our result:

\( \sf - \dfrac{250}{625} = - \dfrac{2 \times 125}{5 \times 125} = \boxed{ \boxed{ \sf - \dfrac{2}{5}}}\)

10) m < BCD = 130º. (option 4).

11) x = 28º. (option 2).

An isosceles triangle is a triangle that has two equal side lengths, hence it also has two equal angle measures.

For item 9, triangle LMO is isosceles, with two angles of 55º, hence the measure of angle M on triangle LMO is given as follows:

<M + 2 x 55 = 180

<M = 70º.

(sum of the internal angles of a triangle is of 180º).

On triangle NMO, the measure is given as follows:

<M = 180 - 70

<M = 110º.

(as it is external to the angle of triangle LMO).

Hence the measure of angle N is given as follows:

<N + 110 + 28 = 180

<N = 42º.

For item 10, the base angle is given as follows:

2x + 80 = 180

2x = 100

x = 50º.

Hence the exterior angle measure is given as follows:

m < BCD = 180 - 50

m < BCD = 130º.

(angle is supplementary with it's exterior).

For item 11, if AB = AC, the base angle is of (x + 20)º, hence the value of x is obtained as follows:

3x + 2(x + 20) = 180

5x + 40 = 180

5x = 140

x = 140/5
