Remember that F(X) = Y
Looking at the graph we can conclude that:
Y > 0 when X < - 4 (up until -∞)
Y = 0 when X = - 4
Y < 0 when X > - 4 (up until +∞)
So choose:
[F(X) = Y] > 0 over the interval ]-∞; -4[
(last option)

Find the following products: a) (−12) × (−11) × (10) b) (−25) × (−8) × (−2) WITH EXPLANATION
Answers
Step-by-step explanation:
Hey, there!!
a. (-12)×(-11)×10
Here, (-)×(-)=(+)
(-12)×(-11)=132
so,
=132×10
=1320.
For b.
(-25)×(-8)×(-2)
(-)×(-)=(+)
(-25)×(-8)=200
so,
=200×(-2) { (+)×(-)=(-)}.
= -400.
Therefore, the answer of a. no. is 1320, and no. b is (-400).

use each of the digits 5 4 3 2 1 exactly once to create two different five digit numbers. Write each number on the line and compare the two numbers by using the symbols < > =
Answers
Answer:
12345 < 54321
21435 > 12534
:
Step-by-step explanation:
Given the digits:
1, 2, 3, 4 and 5
We have to use every digit only once and have to make two different five digit numbers.
Using these 5 numbers only once without repetition, we have many numbers possible.
Let us have a look at a few sets and let us compare them.
Set 1: 12345 and 54321
We can see that 12345 is lesser than 54321.
Therefore, we can write (using lesser than sign):
12345 < 54321
Set 2: 21435 and 12534
We can see that 21435 is greater than 12534.
Therefore, we can write (using greater than sign):
21435 > 12534
1/x - 1/y = 1/4
1/x^2 - 1/y^2 = 3/16
x + y = ...
Answers
GIVEN:
1/x - 1/y = ¼.1/x² - 1/y² = 3/16.TO FIND:
The value of x + y.ANSWER:
Firstly let us assume ,
p = 1/x .q = 1/y .Now the equⁿ s becomes ,
=> p - q = 4 . ........(1)
Also , given that:
=> 1/x² - 1/y² = 3/16.
=> p² - q² = 3/16.
=> (p+q)(p-q) = 3/16.
From (1),
=> 4 (p+q) = 13/16.
=> (p+q) = 13/16 × 1/4.
=> p+ q = 13/64.
On adding (1) and (2) ,
=> 2p = 4 + 13/64.
=> 2p = 256+13/64.
=> p = 269/64 × 1/2.
=> p = 269/128.
Now lets find q ,
=> q = 13/64 - 269/128.
=> q = 26-269/128.
=> q = -243/128.
Hence
p = 269/128.q = -243/128..°. x = 128/269 , y = -128/243

Answers
Answer: she is now 121 feet below sea level.
Step-by-step explanation:
Given, A scientist was in a submarine, 95.7 feet below sea level, studying ocean life.
Over the next ten minutes, she went down 25.3 feet.
Then, she was (95.7+25.3) feet below sea level now. [we will add both distances ]
Then, she was 121 feet below sea level now.
Hence, she is now 121 feet below sea level.

1.) Which of the following is the correct equation for the Pythagorean Theorem, where a and b are the side lengths and c is the length of the hypotenuse?

b.) a^2+b^2=c^2
c.) a^2-b^2=c^2

3.) Find the distance between the points (9, −7) and (5, −4).(1 point)

d.) √137
4.) To find the distance between (17, 3) and (17, −5), Marcia used the following equation. Is Marcia correct? Explain.
D = | 3 − (−5) | = 8
a.) Marcia is not correct. Since the points are in two-dimensions, the distance formula must be used to find the distance.
b.)Marcia is correct. For any pair of points, the distance between the points can be treated as if they are in one-dimension.
c.)Marcia is correct. Since the x-coordinates are the same, the distance between the points can be treated as if they are in one-dimension.
d.)Marcia is not correct. According to the distance formula, the distance should be D=√(17-17)^2+(3-(-5))^2=√8
Answers
Option d for question 4 should be:
d.)Marcia is not correct. According to the distance formula, the distance should be D=√(17-17)^2+(3-(-5))^2=8
Answer:
1. (b) a^2+b^2=c^2
3. (a) 5
4. (d) Marcia is not correct. According to the distance formula, the distance should be D=√(17-17)^2+(3-(-5))^2=8
Step-by-step explanation:
(1) From Pythagoras' theorem, the square of the hypotenuse side of a given right-angled triangle, is equal to the sum of the squares of the other two sides. Now, if the other two sides are a and b, and the hypotenuse is c, then using this theorem, the following holds:
c² = a² + b²
(2) The distance D, between two points (a, b) and (c, d) is given by;
D = √(a-c)² + (b-d)² ----------------(i)
From the question, the points given are (9, -7) and (5, -4):
This means that;
a = 9
b = -7
c = 5
d = -4
Substitute these values into equation (i) and get;
D = √(9-5)² + (-7- (-4))²
D = √(4)² + (-3)²
D = √16 + 9
D = √25
D = 5
Therefore, the distance between these points is 5 units
(4) As explained in question 3 above, Maria is not correct. To find the distance between two points, we use the relation shown in the answer to question 3 above. i.e
D = √(a-c)² + (b-d)²
Since the given points are (17, 3) and (17, -5), it implies that;
a = 17
b = 3
c = 17
d = -5
D = √(17-17)² + (3-(-5))²
D = √(0)² + (8)²
D = √8²
D = 8

the distance from a boy's house to his school is 10km. he left home at 6.30am, cycling at the rate of 4km/h. if he spent 15 minutes on the way waiting for his friend, when did he get to school?
Answers
Answer:
9:15 am
Step-by-step explanation:
First you know the speed and you know the distance.
So now we have to find the time it took for him to get to school(ignore the waiting time first)
time=10/4=2.5h
now we add the waiting time,
2.5h+0.25h(15minutes is the same as 0.25h)=2.75h
convert 0.75h to minuts,
0.75*60=45minutes
6.30+2.45=9.15am
The boy arrived at school at 8:15 am after cycling for 2.5 hours and waiting for 15 minutes.
Given Distance from the boy's house to school = 10 km
Cycling speed = 4 km/h
Time spent waiting for his friend = 15 minutes
Now calculate the time it took for the boy to cycle the distance from his house to the meeting point, excluding the waiting time.
Distance = Speed × Time
10 km = 4 km/h × Time
Time = 10 km / 4 km/h
Time = 2.5 hours
Now, we need to convert the waiting time from minutes to hours, so we can add it to the cycling time.
Waiting time = 15 minutes / 60 minutes/hour
Waiting time = 0.25 hours
Add the cycling time and waiting time to determine the total time it took for the boy to reach school.
Total time = Cycling time + Waiting time
= 2.5 hours + 0.25 hours
=2.75 hours
We need to determine the arrival time by adding the total time to the departure time.
Arrival time = Departure time + Total time
Arrival time = 6.30 am + 2.75 hours
To calculate the arrival time, we need to consider the minutes and hours separately:
Minutes: 30 minutes + (0.75 hours × 60 minutes/hour)
= 30 minutes + 45 minutes
= 75 minutes
Since 75 minutes is more than an hour, we need to adjust the hours and minutes accordingly.
Adding the hours: 6 + 2 = 8
So, the boy arrived at school at 8:15 am.
Therefore, the boy arrived at school at 8:15 am.

Hello, I need some help resolving this problem of Trigonometric Identities. Use the reciprocal identities to resolve it SinA+cosA*cotA= cscA
Answers
Answer:
Please see steps below
Step-by-step explanation:
Start by writing all trig functions in the equation in terms of their simplest forms using the two basic trig functions: [tex]sin(\alpha) \,\,and\,\,cos(\alpha)[/tex]:
[tex]sin(\alpha)+ cos(\alpha)\,\frac{cos(\alpha)}{sin(\alpha)} = \frac{1}{sin(\alpha)}[/tex]
Now work on the left side (which is the most complicated one), trying to simplify it using the properties for adding fractions with different denominators:
[tex]sin(\alpha)+ cos(\alpha)\,\frac{cos(\alpha)}{sin(\alpha)}=sin(\alpha)+\frac{cos^2(\alpha)}{sin(\alpha)} =\frac{sin^2(\alpha)}{sin(\alpha)} +\frac{cos^2(\alpha)}{sin(\alpha)}=\frac{sin^2(\alpha)+cos^2(\alpha)}{sin(\alpha)}=\frac{1}{sin(\alpha)}[/tex]
where in the last step we have used that the Pythagorean identity for:
[tex]sin^2(\alpha)+cos^2{\alpha)=1[/tex]
Notice that we arrived at the expression: [tex]\frac{1}{sin(\alpha)}[/tex], which is exactly what appears on the other side of the initial equation/identity we needed to prove, so the prove has been completed.
