What Is the solution for y?
3x-4=5y+3
Answer:
slope=1.200/2000=0.600
x-intercept =7/3=2.3333
y-intercept =7/-5--1.40000
Step-by-step explanation:
the x and y intercept and the aloe are called line of properties.
y tells us how far the line goes
x tells us how far it goes
m is the slope of gradient i.e. how steep the like is
bis y-intercept i.e. where the line line crosses the y
Suppose you drop a tennis ball from a height of 11 feet. After the ball hits the floor, it rebounds to 75% of its previous height. How high will the ball rebound after its third bounce? Round to the nearest tenth.
Answer:
4.64 ft
Step-by-step explanation:
75 % = .75

Which second degree polynomial function has a leading coefficient of –1 and root 4 with multiplicity 2? f(x) = –x2 – 8x – 16 f(x) = –x2 8x – 16 f(x) = –x2 – 8x 16 f(x) = –x2 8x 16
Using the Factor Theorem, the second degree polynomial function that has a leading coefficient of –1 and root 4 with multiplicity 2 is given by:
f(x) = -x² + 8x - 16
What is the Factor Theorem?The Factor Theorem states that a polynomial function with roots [tex]x_1, x_2, \codts, x_n[/tex] is given by:
[tex]f(x) = a(x - x_1)(x - x_2) \cdots (x - x_n)[/tex]
In which a is the leading coefficient.
In this problem, we have that:
The leading coefficient is of a = -1.There is a root of 4 with multiplicity 2, hence [tex]x_1 = x_2 = 4[/tex].Thus, the polynomial is given by:
f(x) = -(x - 4)(x - 4)
f(x) = -(x² - 8x + 16)
f(x) = -x² + 8x - 16

a. What can you conclude about LOBC? Justify your answer. b. Write and solve an equation to find the length of OE. c. Explain how you know your answer to part (b) is reasonable. d. How can you use the length you found in part (b) to find the length of one side of the red sail in the logo for the showroom display? What is that length?
The angle OBC is 90 degrees, the equation is 18r = 144, r = 8 feet, and the length of the AB is 16 feet which is the length of the red sail in the logo.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
We have the figure shown in the picture with dimensions.
a) As we can see, the AOB is the diameter of the circle which is perpendicular to the CBD
So the angle ∠OBC will be a right angle.
∠OBC = 90 degree.
b) Length OE is the radius of the circle.
Let's suppose OE = r
Then in a right angle triangle OBC where ∠OBC = 90 degrees.
Applying Pythagoras theorem:
OC² = CB² + OB²
(CE + OE)² = CB² + OB²
CE = 9 ft, OE = r, CB = 15 feet, and OB = r (radius of the circle)
(9 + r)² = 15² + r²
81 + 18r + r² = 15² + r²
18r = 144
r = 8 feet
OE = r = 8 feet
c)
As the angle ∠OBC = 90 degrees, that's why the triangle OBC becomes a right angle triangle and OB⊥CB.
d)
In the circle, there is a red triangle, we can find one of the lengths of the triangle which is AB.
AB is the diameter of the circle
r = 8
Diameter AB = double the radius = 2(8) = 16 feet
AB = 16 feet
Thus, the angle OBC is 90 degrees, the equation is 18r = 144, r = 8 feet, and the length of the AB is 16 feet which is the length of the red sail in the logo.

The percentage for the interval of values between 75 and 85 has to be found out. From the 68%, the interval is,
[tex]P(\mu - \sigma < X < \mu + \sigma) = 68\%\\P(80 - 5 < X < 80+ 5) = 68\%\\P(75 < X < 85) = 68\%[/tex]

Using vector concepts, it is found that:
The component form is of approximately (-9.58, 7,22). It means that the ship is about 9.58 miles to the west and about 7.22 miles to the north of where the ship left the port.
How can a vector be represented in component notation?Given a magnitude M and angle [tex]\theta[/tex], then a vector V can be represented as follows in component notation:
[tex]V = (M\cos{\theta}, M\sin{\theta})[/tex]
In this problem, the magnitude and the angle are given, respectively, by:
[tex]M = 12, \theta = 143^\circ[/tex]
Hence:
V = [12cos(143º), 12sin(143º)] = (-9.58, 7,22).
Which means a displacement of 9.58 miles to the west(negative x = west) and 7.22 miles to the north(positive y = north).

So if the corrected weight is to the nearest gram, the bag can weigh ± 1 gm from the corrected weight
So the error is 1/1750 = 1 /1750 x 100 % = 5.71%
