First off, remember that finding the x-intercepts means setting y equal to zero and solving for the x-values, so this question is really asking you to "Solve 4x2 – 2x – 5 = 0".
Now, let's start the completing-the-square process. To begin, we have the original equation (or, if we had to solve first for "= 0", the "equals zero" form of the equation). In this case, we were asked for the x-intercepts of a quadratic function, which meant that we set the function equal to zero
Answer:
D . x + 4Step-by-step explanation:
(x² + 6x + 8) / (x + 2) =(x² + 2x + 4x + 8) / (x + 2) = (x + 2)(x + 4) / (x + 2) = x + 4Correct choice is D
A 108-inch pipe is cut into two pieces. One piece is five times the length of the other. Find the lengths of the two pieces.
The short piece is
inches long
Answers
Answer:
18 and 90
Step-by-step explanation:
If we express in units,
Long piece has 5 units
Short piece has 1 unit
total 6 units
108/6 = 18 inch
which is the length of 1 unit
short = 18 * 1
long = 18 *5

An airport limousine can accommodate up to four passengers on any one trip. The company will accept a maximum of six reservations for a trip, and a passenger must have a reservation. From previous records, 35% of all those making reservations do not appear for the trip.A) If six reservations are made, what is the probability that at least one individual with a reservation cannot be accommodated on the trip?B) If six reservations are made, what is the expected number of available places when the limousine departs?C) Suppose the probability distribution of the number of reservations made is given in the accompanying table.Number of reservations 3 4 5 6Probability 0.09 0.25 0.32 0.34Let X denote the number of passengers on a randomly selected trip. Obtain the probability mass function of X.
Answers
Answer:
a) 0.3191 = 31.91% probability that at least one individual with a reservation cannot be accommodated on the trip.
b) The expected number of available places when the limousine departs is 0.1.
c) [tex]P(X = 3) = 0.09[/tex]
[tex]P(X = 4) = 0.25[/tex]
[tex]P(X = 5) = 0.32[/tex]
[tex]P(X = 6) = 0.34[/tex]
Step-by-step explanation:
For each reservation, there are only two possible outcomes. Either the person appears for the trip, or the person does not. The probability of a person appearing for the trip is independent of any other person. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
The expected value of the binomial distribution is given by:
[tex]E(X) = np[/tex]
The company will accept a maximum of six reservations for a trip, and a passenger must have a reservation.
This means that [tex]n = 6[/tex]
35% of all those making reservations do not appear for the trip.
This means that 100 - 35 = 65% appear, so [tex]p = 0.65[/tex]
A) If six reservations are made, what is the probability that at least one individual with a reservation cannot be accommodated on the trip?
This will happen if more than four appear, as the limousine can accommodate up to four passengers on any one trip. So
[tex]P(X > 4) = P(X = 5) + P(X = 6)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 5) = C_{6,5}.(0.65)^{5}.(0.35)^{1} = 0.2437[/tex]
[tex]P(X = 6) = C_{6,6}.(0.65)^{6}.(0.35)^{0} = 0.0754[/tex]
[tex]P(X > 4) = P(X = 5) + P(X = 6) = 0.2437 + 0.0754 = 0.3191[/tex]
0.3191 = 31.91% probability that at least one individual with a reservation cannot be accommodated on the trip.
B) If six reservations are made, what is the expected number of available places when the limousine departs?
The expected number of arrivals is given by:
[tex]E(X) = np = 6*0.65 = 3.9[/tex]
Since the are four places:
4 - 3.9 = 0.1
The expected number of available places when the limousine departs is 0.1.
C) Suppose the probability distribution of the number of reservations made is given in the accompanying table.Number of reservations 3 4 5 6Probability 0.09 0.25 0.32 0.34Let X denote the number of passengers on a randomly selected trip. Obtain the probability mass function of X.
This is the probability of each outcome. So
[tex]P(X = 3) = 0.09[/tex]
[tex]P(X = 4) = 0.25[/tex]
[tex]P(X = 5) = 0.32[/tex]
[tex]P(X = 6) = 0.34[/tex]

1. Solve the equation using the quadratic formula
The Quadratic formula provides the solution for [tex]Ax^{2} +Bx+C=0[/tex]
in which A, B, and C are numbers (or coefficients), as follows:
[tex]\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex]
2. Determine the quadratic equation’s coefficients A, B, and C
The coefficients of our equation, [tex]5x^{2} +15x-140=0[/tex], are:
A = 5
B = 15
C = -140
3. Plug these coefficients into the quadratic formula
[tex]\frac{-b+\sqrt{b^{2}-4ac } }{2a}=\frac{-15+\sqrt{15^{2}-4x5x-140 } }{2x5}[/tex]
Calculate the expression inside the parentheses.
Simplify exponents and square roots.
[tex]\frac{-15+\sqrt{15^{2}-4x5x-140 } }{2x5}[/tex]
[tex]\frac{-15+\sqrt{225-4x5x-140 } }{2x5}[/tex]
Perform any multiplication or division, from left to right.
[tex]\frac{-15+\sqrt{225-20x-140 } }{2x5}[/tex]
[tex]\frac{-15+\sqrt{225-2800 } }{2x5}[/tex]
[tex]\frac{-15+\sqrt{3025} }{2x5}[/tex]
[tex]\frac{-15+\sqrt{3025} }{10}[/tex]
to get the result:
[tex]x=\frac{-15+\sqrt{3025} }{10}[/tex]
4. Simplify square root

The prime factorization of 3025 is 5² • 11²
Write the prime factors.
[tex]\sqrt{3025}[/tex] = √5 • 5 • 11 • 11
Group the prime factors into pairs and rewrite in exponent form.
√5 • 5 • 11 • 11 = [tex]\sqrt{5^{2}x11^{2} }[/tex]
Use rule [tex]\sqrt{x^{2} }[/tex] = x to simplify futher.
[tex]\sqrt{5^{2}x11^{2}}[/tex] = 5 • 11
5 • 11 = 55
5. Solve the equation for x

B=25000/(tan(58)) and A=25000/(tan(34))
B-A=25000/(tan58-tan34)=27003ft
The distance between point A and point B is 23195 ft.
What is the Angle of Depression ?For an object below the level, the angle created by the line of sight and the horizontal plane is called the Angle of Depression.
It is given that
A pilot is flying over a straight highway.

The pilot is flying at an altitude of 25,000 ft.
Tan [tex]\rm \theta[/tex] = Height / (Distance of the point and the plane horizontally )
Tan 32 = 25 /x
x = 25000 / tan 32
x = 40064 ft
tan 56 = 25/x
x = 25000/tan 56
x = 16869 ft

What is the weight, in Newtons, of a person on Earth whose mass is 90 kilograms? Gravity near the Earth's surface is 9.8 m/s2.
What is the answer rounded to the nearest tenth?
Answers
Answer:
W = 882 N
Step-by-step explanation:
Given that,
The weight of a person, W = 90 kg
The value of acceleration due to gravity, g = 9.8 m/s²
We need to find the weight of the person on Earth. The formula for the weight of an object is given by :
W = mg
Substitute all the values,
W = 90 kg × 9.8 m/s²
W = 882 N
So, the weight of the person is equal to 882 N.
