Step-by-step explanation:

Answer:

a) The estimates for the solutions of [tex]4\cdot x^{2}-4\cdot x -1 = 0[/tex] are [tex]x_{1}\approx -0.25[/tex] and [tex]x_{2} \approx 1.25[/tex].

b) The estimates for the solutions of [tex]4\cdot x^{2}-4\cdot x -1 = 2[/tex] are [tex]x_{1}\approx -0.5[/tex] and [tex]x_{2} \approx 1.5[/tex]

Step-by-step explanation:

From image we get a graphical representation of the second-order polynomial [tex]y = 4\cdot x^{2}-4\cdot x -1[/tex], where [tex]x[/tex] is related to the horizontal axis of the Cartesian plane, whereas [tex]y[/tex] is related to the vertical axis of this plane. Now we proceed to estimate the solutions for each case:

a) [tex]4\cdot x^{2}-4\cdot x -1 = 0[/tex]

There are two approximate solutions according to the graph, which are marked by red circles in the image attached below:

[tex]x_{1}\approx -0.25[/tex], [tex]x_{2} \approx 1.25[/tex]

b) [tex]4\cdot x^{2}-4\cdot x -1 = 2[/tex]

There are two approximate solutions according to the graph, which are marked by red circles in the image attached below:

[tex]x_{1}\approx -0.5[/tex], [tex]x_{2} \approx 1.5[/tex]

Answer:

  slope = 2

Step-by-step explanation:

See the attachment for the markup.

It is usually convenient to choose places where the graph crosses grid intersections. Here, the graph crosses the x- and y-axes at integer values, so those points could be used, for example. We chose points away from the axes so that the rise and run lines could be seen more easily.

The graph has a rise/run of ...

  slope = rise/run = 2/1 = 2

The slope of the line is 2.

Step-by-step explanation:

Given question is incomplete; here is the complete question,

Katie runs from her house, east 5 blocks, south 3 blocks, west 5 blocks, and north 4 blocks before walking back home. Regarding her jog only: Her total time it takes her 35 minutes. If city block is about 0.5 miles (0.8 km), what is her velocity in mi/h and m/s?

Katie runs from her house, East 5 blocks, South 3 blocks, West 5 blocks and North 4 blocks.

Since, velocity = [tex]\frac{\text{Displacement}}{\text{Time}}[/tex]

Displacement of Katie from initial position = (3 + 3) blocks

                                                                       = 6 blocks

Since, each block measure 0.5 miles,

Displacement = 6 × 0.5

                       = 3 miles

Time taken to cover the distance = 35 minutes ≈ 0.583 hours

Therefore, velocity of Katie = [tex]\frac{3}{0.583}[/tex]

                                              = 5.15 miles per hour towards South

Displacement (in m) = 6 × 0.8

                                   = 4.8 km

                                   ≈ 4800 m

Velocity (in m per hour) = [tex]\frac{4800}{0.583}[/tex]

                                         = 8233.27 m per hour towards South

Playing video games helps me if I have a rough time, I started around 2019. I play adventure type video games, not sure if raft counts, but that is a game I play too often with my friends. I think that video games probably could be played in cars as well but I dont know what else it can be or will be played on. Definitely will not be a single platform, people are too greedy everyone wants a better state then others. (not sure if that makes sense)

hope this helps :))

Step-by-step explanation:

i did a cm to feet calcu-lator

have good day

The correct answer is 4 feet 17 inches is 160.5 c.m.

The process to convert cm to feet is simple. 1 cm. is equal to 0.025 feet. So you must multiple the unit by 0.025.

Given:

1 feet = 38.48 cm.

1 cm. = 0.025 feet.

160.5 cm = (0.025/1) * 160.5

160.5 cm = 4.1709 feet  

4.1709 feet  

4.1709 feet  = 4 feet + 1709 inches.

We can 4.1709 feet which is equal to 4 feet 17 inches.

Therefore, 160.5 cm is equal to  4 feet 17 inches.

The required measure of the missing angles are m∠1 = 50°, m∠2 = 90°, m∠3 = 60°, m∠4 = 60°, m∠5 = 60°, m∠6 = 60°, and m∠7 = 100°.

Two triangles are said to be congruent if their corresponding sides and angles are equal.

For finding m∠1,

Here m∠2 = 90° as per the figure it is the right angle.

m∠1 + 40° +  m∠2 = 180°

m∠1 + 40° +  90° = 180°

m∠1 = 50°

For finding m∠3,

m∠2 + m∠3 +  30° = 180°

90° +  m∠3 +  30° = 180°

m∠3 = 60°

For finding m∠4 and m∠5

We can see that this triangle is equilateral so, m∠4 = m∠5 = 60°

For finding m∠6 and m∠7

m∠6 + m∠7 +  20° = 180°

60° + m∠7 +  20° = 180°

m∠7 = 100°

Thus, the required measure of the missing angles are m∠1 = 50°, m∠2 = 90°, m∠3 = 60°, m∠4 = 60°, m∠5 = 60°, m∠6 = 60°, and m∠7 = 100°.
