Starting at 300 feet away, a car drives towards you. IT then passes you by at a constant speed of 48 feet per second. The distance d (in feet) of the car from you after t seconds is given by the equation d=|300-48t|. AT what times is the car 60 feet from you?
The car is 60 feet away from you after___seconds and after _____ seconds.
Explain what 48t represents in the given equation.
The car is at 60ft from you 5 seconds after it starts moving and 7.5 seconds after it starts moving.
The 48*t part means the number of feet that the car moves in t seconds
At what times is the car at 60ft from you?We know that the absolute value equation that models the distance is:
d(t) = |300 - 48*t|
Then what we need to solve is d(t) = 60, this is:
d(t) = 60 = |300 - 48*t|
That absolute value equation can be represented in two forms:
300 - 48*t = 60
300 - 48*t = -60
Solving these two we get the two times at which the car is at 60ft from you.
-48*t = 60 - 300
t = (60 - 300)/(-48) = 5
t = (-60 - 300)/(-48) = 7.5
So the car is at 60ft from you 5 seconds after it starts moving and 7.5 seconds after it starts moving.
The 48*t part means the number of feet that the car moves in t seconds.

Which represent geometric sequences? A marathon runner runs half of a race, then runs half the distance left to the finish line, then runs half the distance that still remains, and so on. The first movie rental costs $2, and each additional rental costs $1. 10, 1, 0.1, 0.01, … –4, 20, –100, 500, … –1, 5, 11, 17, 23, …
Answer:
Step-by-step explanation:
1). Let the length of a marathon race = x miles
Marathon runner runs this race in the sequence formed as,
[tex]\frac{x}{2},\frac{x}{4},\frac{x}{8}.........[/tex]
Common ratio = [tex]\frac{\frac{x}{4}}{\frac{x}{2}}[/tex]
= [tex]\frac{x}{4}\times \frac{2}{x}[/tex]
= [tex]\frac{1}{2}[/tex]
Therefore, it's a geometric sequence.
2). First movie rental cost = $2
Followed by each additional movie rental cost = $1
Therefore, rental of movies will be in the form of a linear equation,
y = 2x + 1
where x = number of movies
And y = Rental of movies
It's not a geometric sequence.
3). 10, 1, 0.1, 0.01.......
Ratio in 2nd and 1st term = [tex]\frac{1}{10}=0.1[/tex]
Ratio in 3rd and 2nd term = [tex]\frac{0.1}{1}=0.1[/tex]
Therefore, ratio in each term is common.
Sequence formed will be a geometric sequence.
4). [tex]\sum_{k=1}^{7}4(0.2)^{k-1}[/tex]
Expression represents a common ratio of 0.2,
Therefore, expression given will represent a geometric sequence.
5). -4, 20, -100, 500, ...........
Ratio of 2nd and 1st term = [tex]\frac{20}{-4}[/tex] = -5
Ratio of 3rd and 2nd term = [tex]\frac{-100}{20}[/tex]
= -5
There is a common ratio = -5
Therefore, it's a geometric sequence.
6). -1, 5, 11, 17.........
Ratio of 2nd and 1st term = [tex]\frac{5}{-1}=-5[/tex]
Ratio of 3rd and 2nd term = [tex]\frac{11}{5}=2.2[/tex]
-5 ≠ 2.2
Therefore, sequence is not a geometric sequence.
7). -500, 100, -20, 4........
Ratio of 2nd and 1st term = [tex]\frac{100}{-500}=-\frac{1}{5}[/tex]
Ratio of 3rd and 2nd term = [tex]\frac{-20}{100}=-\frac{1}{5}[/tex]

Factor $9p^2 + 30p + 25.$ pls help
Answer:
(3p + 5)^2
Step-by-step explanation:
9p^2 + 30p + 25
9p^2 is the square of 3p = a
25 is the square of 5 = b
This may be the square of a binomial.
We need to check the middle term.
(a + b)^2 = a^2 + 2ab + b^2
2ab = 2(3p)(5) = 30p
This is the square of a binomial.
9p^2 + 30p + 25 = (3p + 5)^2
A store sold 550 video games during the month of December. If this made up 12.5% of its yearly video games scales, about how many video games did the store sell all year?
Answer:
The store sold 4,400 video games all year.
Step-by-step explanation:
Percentages
The x percent of a number N is calculated as:
[tex]\displaystyle P=\frac{x}{100}*N[/tex]
If the value of P is known, then:
[tex]\displaystyle N=\frac{100}{x}*P[/tex]
We know the store sold P=550 video games during the month of December and it corresponds to the x=12% of its yearly games sales (N).
Let's calculate N:
[tex]\displaystyle N=\frac{100}{12.5}*550[/tex]
N = 4,400
The store sold 4,400 video games all year.
The angle by which turns clockwise about point P to coincide with is
.
If from point P, a point D is drawn directly opposite point C so that D, P, and C are on the same straight line, the angle by which turns counterclockwise about point P to coincide with is
The angle by which turns counterclockwise about point P to coincide with is 180 degree angle
What is 180 degree angle?
The angle which forms a straight line is called the 180-degree angle. A 180-degree angle is a straight angle and it is exactly half of a revolution. The two arms of the angle which are making 180-degree are just opposite to each other from the common vertex.
The points D, P and C forms a straight line.
So, if it turns clockwise about Point P, it would make an angle of 180 degree.
as the point D and C are of equal lengths and opposite to each other, the angle from P turning clockwise makes 180 degree angle.

2 What is the GCF of y2(y + 1) and y(y + 2)?
Answer:
the answer is Y
Step-by-step explanation:
The greatest common factor (GCF) of two polynomial expressions is y.
The greatest common factor (GCF) of two polynomial expressions is the polynomial with the largest set of factors that is a factor of both polynomials.
To find the GCF of y2(y + 1) and y(y + 2), we can factor each polynomial:
y2(y + 1) = y(y)(y + 1)
y(y + 2) = y(y + 2)
The only factor that both polynomials have in common is y, so the GCF is y.
Here is the solution in more detail:
Factor each polynomial.
y2(y + 1) = y(y)(y + 1)
y(y + 2) = y(y + 2)
Find the factors that are common to both polynomials.
The only factor that both polynomials have in common is y.
The GCF is the polynomial with the largest set of factors that is a factor of both polynomials.
The GCF is y.
Therefore, the GCF of y2(y + 1) and y(y + 2) is y.

what number is 5 more than 1/3 of 18
Answer:11
Step-by-step explanation:
18*1/3+5=11
Answer:
11
Step-by-step explanation:
To find the number that is 5 more than [tex]\frac{1}{3}[/tex] of 18, we can start by evaluating what [tex]\frac{1}{3}[/tex] is:
[tex]\frac{1}{3}[/tex] of 18
⇒ [tex]\frac{1}{3} \times 18[/tex]
To multiply a whole number by a fraction, we can convert the whole number into a fraction by giving it a denominator of 1:
⇒ [tex]\frac{1}{3} \times \frac{18}{1}[/tex]
⇒ [tex]\frac{18}{3}[/tex] [This is the same as 18 ÷ 3]
⇒ [tex]\bf 6[/tex]
Now that we have the value of [tex]\frac{1}{3}[/tex] of 18, we can simply add to it to find the number that is 5 more than [tex]\frac{1}{3}[/tex] of 18:
[tex](\frac{1}{3} \times 18) + 5[/tex]
⇒ [tex]6 + 5[/tex]
⇒ [tex]\bf 11[/tex]
∴ The number we are looking for is 11.

how you can use Triangle congruence to solve real-world problems? give 3 examples.
Answer:
1.Many pairs of triangles designed into a building, for example as roof ends, would be congruent, so the roof beam and the top edges of the walls are horizontal.
2.The congruent triangle is used in most of the building that are design to stay in bad conditions and Strong winds for Example the Sydney Bridge.
3.in real life two triangles are rarely exactly congruent. However they are crucial in the construction of large man-made structures. This is because a triangle is the most stable shape and the congruence is needed to create even surfaces.
how many natural number n is the function 5n^2-9/2n+6 also a natural number?
The function (5n² - 9) / (n + 3) is a natural number for n = 3 and n = 15.
A function is given which is (5n² - 9) / (2n + 6).
We have to find the value of natural number n for which the given function is also natural number.
What do you mean by natural numbers ?
Natural numbers are known as the counting numbers which starts from 1 and end at infinity and also includes the whole numbers excluding 0.
As per the question ;
(5n² - 9) / (2n + 6) is a natural number for the value of n which is also a natural number.
Let's assume ;
(5n² - 9) / (2n + 6) = k
or
(5n² - 9) / (n + 3) = 2k
So , we can say that (5n² - 9) / (n + 3) is an even number.
We know that ;
Dividend ÷ Divisor = Quotient
If we divide (5n² - 9) by (n + 3) we will get ;
Quotient = 5n - 15
and
Remainder = 36
We can write it as ;
(5n² - 9) ÷ (n + 3) = (5n - 15) + {36 / (n+ 3)}
Here ;
36 / (n+ 3) is a natural number and n is a natural number.
Assume ;
n = 1 , 3 , 6 , 9 , 15 , 33
Let's check ;
for n = 1 ;
(5n - 15) + {36 / (n+ 3)} will be ;
= (5 - 15) + {36 / (1+ 3)}
= -1
for n = 3 ;
(5n - 15) + {36 / (n+ 3)} will be ;
= (15 - 15) + {36 / (3+ 3)}
= 6
for n = 6 ;
(5n - 15) + {36 / (n+ 3)} will be ;
= (30 - 15) + {36 / (6+ 3)}
= 19
for n = 9 ;
(5n - 15) + {36 / (n+ 3)} will be ;
= (45 - 15) + {36 / (9+ 3)}
= 33
for n = 15 ;
(5n - 15) + {36 / (n+ 3)} will be ;
= (75 - 15) + {36 / (15+ 3)}
= 62
for n = 33 ;
(5n - 15) + {36 / (n+ 3)} will be ;
= (165 - 15) + {36 / (33+ 3)}
= 151
So , we found that only for values of n = 3 and n = 15 , the value of (5n - 15) + {36 / (n+ 3)} is also an even number.
Thus , the function (5n² - 9) / (n + 3) is a natural number for n = 3 and n = 15.
