5y> 30 graph number line

Answers

Answer 1

y>6 is the solution of the inequality and graph of the inequality is given in attachment.

The given inequality is 5y>30.

Five times of y greater than thirty.

We have to find the solution of the inequality.

Divide both sides by 5:

y>30/5

When 30 is divided by five we get six.

y>6

Hence, y>6 is the solution of the inequality.

In Rebecca's neighborhood, 89% of the houses have garages and 48% have a
garage and a pool. What is the probability (in percent) that a house in her
neighborhood has a pool, given that it has a garage? Round your answer to 1
decimal place.

Answers

why are there two of these?
Answer:

53.9

Step-by-step explanation:

89% of all houses have garages and 48% have garages and pools. We try to find houses with a pool that have a garage. Let's assume that there are 100 houses in her neighborhood. then 89 of them have garages and 48 of them have garages and pools. 48 / 89 = about 0.5393. Conver this to percent and we get 53.9

Answers

The incorrect statement is:

B. The three-part inequality - 5x < 15x^2 < 3 is equivalent to - 6 ≤ 5 - x < 6.

In the given statement, there is an error in the inequality. The correct statement should be:

The three-part inequality - 5x < 15x^2 < 3 is equivalent to - 6 ≤ 5 - x and 5 - x < 6.

When solving the three-part inequality - 5x < 15x^2 < 3, we need to split it into two separate inequalities. The correct splitting should be:

- 5x < 15x^2 and 15x^2 < 3

Simplifying the first inequality:

- 5x < 15x^2

Dividing by x (assuming x ≠ 0), we need to reverse the inequality sign:

- 5 < 15x

Simplifying the second inequality:

15x^2 < 3

Dividing by 15, we get:

x^2 < 1/5

Taking the square root (assuming x ≥ 0), we have two cases:

x < 1/√5 and -x < 1/√5

Combining these inequalities, we get:

- 5 < 15x and x < 1/√5 and -x < 1/√5

Therefore, the correct statement is that the three-part inequality - 5x < 15x^2 < 3 is equivalent to - 6 ≤ 5 - x and 5 - x < 6, not - 6 ≤ 5 - x < 6 as stated in option B.

In a downhill ski race, surprisingly, little advantage is gained by getting a running start. (This is because the initial kinetic energy is small compared with the gain in gravitational potential energy even on small hills.) To demonstrate this, find the final speed in m/s and the time taken in seconds for a skier who skies 67.0 m along a 25° slope neglecting friction for the following two cases. (Enter the final speeds to at least one decimal place.)
(a)
starting from rest = ?
final speed =?

(b)
starting with an initial speed of 3.40 m/s
final speed = ? m/s
time taken = ?s

Answers

a. The final speed starting from rest is 23.6 m/s.

The time starting from rest is 5.7 seconds.

b. Starting with an initial speed of 3.40 m/s, the final speed (v) is 23.8 m/s.

Starting with an initial speed of 3.40 m/s, the time taken is 4.9 seconds.

How to calculate the final speed?

In accordance with the law of conservation of energy, the potential energy possessed by a physical object at the top is equal to the kinetic energy possessed by a physical object at the ground:

PE = KE

mgh = ½mv²

2mgh = mv²

2gh = v²

v = √2gh

Where:

P.E represents potential energy.K.E represents kinetic energy.m represents the mass.h represents the height.g is acceleration due to gravity.

Note: h = Dsinθ and acceleration due to gravity is equal to 9.8 m/s².

Part a.

Starting from rest, the final speed (v) can be calculated as follows;

v = √2gDsinθ

v = √(2 × 9.8 × 67.0 × sin25)

v = 23.6 m/s.

Since acceleration is constant because the ski slope is uniformly inclined, the time taken (t) is given by the race distance (D) divided by the average of the initial speed (u) and final speed (v):

[tex]t=\frac{2D}{u+\sqrt{v^2 + 2gDsin \theta} } \\\\t=\frac{2(67)}{0+\sqrt{0^2 + 2 \times 9.8 \times 67 sin 25} }[/tex]

Time, t = 134/23.6

Time, t = 5.7 seconds.

Part b.

Starting with an initial speed of 3.40 m/s, the final speed (v) can be calculated as follows;

v = √(u² + 2gDsinθ)

v = √(3.40² + 2 × 9.8 × 67.0 × sin25)

v = √(11.56 + 554.98)

v = 23.8 m/s.

Starting with an initial speed of 3.40 m/s, the time taken (t) can be calculated as follows;

[tex]t=\frac{2D}{u+\sqrt{v^2 + 2gDsin \theta} } \\\\t=\frac{2(67)}{3.40+\sqrt{3.40^2 + 2 \times 9.8 \times 67 sin 25} }[/tex]

Time, t = 134/27.2

Time, t = 4.9 seconds.

how is y=2sin(2pix)+1 related to y=sinx or y=cosx?

Answers

y = 2sin(2πx) + 1 is an amplitude-scaled, period-halved, vertically shifted version of y = sin(x). It is important to note that y = cos(x) is not directly related to y = 2sin(2πx) + 1 as it represents a different trigonometric function.

The equation y = 2sin(2πx) + 1 is related to y = sin(x) and y = cos(x) through trigonometric transformations. Let's break down the relationship:

Amplitude: The coefficient 2 in front of sin(2πx) in y = 2sin(2πx) + 1 indicates that the amplitude of the sine function has been doubled compared to y = sin(x). The amplitude determines the maximum and minimum values of the function.

Period: In y = 2sin(2πx) + 1, the argument of sin(2πx) is 2πx, resulting in a period that is halved compared to y = sin(x). The period is the length of one complete cycle of the function.

Phase shift: There is no phase shift in y = 2sin(2πx) + 1. The function y = sin(x) has a phase shift of 0.

Vertical shift: The constant term +1 in y = 2sin(2πx) + 1 represents a vertical shift upward by 1 unit compared to y = sin(x). It shifts the entire graph vertically.

Overall, y = 2sin(2πx) + 1 is an amplitude-scaled, period-halved, vertically shifted version of y = sin(x). It is important to note that y = cos(x) is not directly related to y = 2sin(2πx) + 1 as it represents a different trigonometric function.

Two roots of the equation are,

⇒x = 4.55, - 0.55

We have to given that,

A curve has the equation,

⇒ y = 2x² - 8x - 5

Now, We know that,

If the curve intercept at x - axis, then y value is zero.

Hence, We get;

⇒ y = 2x² - 8x - 5

⇒ 0 = 2x² - 8x - 5

⇒ 2x² - 8x - 5 = 0

By quadratic formula, we get;

⇒ x = (- (- 8)) ± √(- 8)² - 4×2×- 5) / 2×2

⇒ x = (8 ± √64 + 40) / 4

⇒ x = (8 ± 10.2) / 4

Take positive sign,

⇒x = (8 + 10.2) / 4

⇒ x = 18.2/4

⇒ x = 4.55

Take negative sign,

⇒ x = (8 - 10.2) / 4

⇒ x = - 2.2/4

⇒ x = - 0.55

Hence, Two roots of the equation are,

⇒x = 4.55, - 0.55
