The y-intercept of function g(x) is 9 greater than the y-intercept of function f(x).
Explanation:The question is asking for the difference in the y-intercepts of two quadratic functions f(x) and g(x). The minimum point of a function gives us both the x-value of the vertex and the y-intercept. Here, for f(x), the minimum point is given as (-2,-3) which means the y-intercept is -3. Similarly, for the function g(x)=-(x+2)(x-3), expanding this equation gives us g(x) = -x^2 + x + 6. Here, we see that the constant term, 6, is the y-intercept. Therefore, the difference in the y-intercepts of g(x) and f(x) is 6 - (-3) = 9.

Theorem of intersection of two cords : If two cords AB and CD intersecting at point P, then
[tex]|AP|\times |PB|=|CP|\times |PD|[/tex]
Using the theorem of intersection of two cords, we get
[tex](n-2)\times 16=8\times (n+8)[/tex]
Use distribution property,
[tex]16n+32=8n+64[/tex]
[tex]16n-8n=64-32[/tex]
[tex]8n=32[/tex]
Divide both sides by 8.
[tex]n=\frac{32}{8}[/tex]
[tex]n=4[/tex]
Therefore the value of n is 4.
Find an explicit formula for the arithmetic sequence 37, 74, 111, 148
Let us observe the given series 37,74,111,148
Here, the first term (a) = 37
Common difference(d) = 74-37 = 37
Hence, the given series is in Arithmetic progression.
Hence the nth term of the series is given by:
[tex] a_{n}=a+(n-1)d [/tex]
Substituting the values of 'a' and 'd'.
[tex] a_{n}=37+37(n-1) [/tex]
Therefore, it is the required explicit formula.

The graph shows the shape of an arched bridge cable. What does the y-intercept represent?
The total length of the cable is 15 m.
The left end of the cable is 15 m above the roadway.
The minimum distance between the cable and roadway is 15 m.
The total length of the road is 15 m.
Answer:
The left end of the cable is 15 m above the roadway
Step-by-step explanation:
Let
x----> the horizontal distance from left end of cable (m)
y----> the height above roadway (m)
we know that
The y-intercept is the value of y when the value of x is equal to zero
In this problem
The y-intercept is the height above roadway (m) when the distance from end of cable is equal to zero
so
The y-intercept is the point (0,15)
so
The left end of the cable is 15 m above the roadway
The left end of the cable is 15 m above the roadway]

Select the scenarios that correctly represent the given graph.
Answer:
The correct options are 1 and 2.
Step-by-step explanation:
From the given graph it is clear that it is a graph of an exponential function and the graph passes through the points (0,100) and (1,150).
The general form of an exponential function is
[tex]y=ab^x[/tex] .... (1)
Where, a is the initial value and b is growth rate.
The initial value is 100 because the y-intercept of the graph is 100.
The graph passes through (1,150). Put y=150, a=100 and x=1 in the above formula to find the value of b.
[tex]150=100b^1[/tex]
Divide both the sides by 100.
[tex]1.5=b[/tex]
The value of b is 1.5.
Substitute a=100 and b=1.5 in equation (1).
[tex]y=100(1.5)^x[/tex]
It means the value is 1.5 times larger in every unit of time.
It can be written as
[tex]y=100(1+0.5)^x[/tex]
It means the initial value increased by 50% per unit of time.
So, the required scenarios are
1. The amount of money in a bank account increased by 505 per year.
2. The amount of a substance is one and a half times larger after every minute.
Therefore the correct options are 1 and 2.
what does a^2+b^2=C^2 mean
The equation a² + b² = c² represents the Pythagorean theorem, which describes the relationship between the sides of a right triangle. It states that the square of the hypotenuse is equal to the sum of the squares of the other two sides. For example, in a triangle with legs of 3 and 4 units, the hypotenuse would be 5 units.
The equation a² + b² = c² represents the Pythagorean theorem in mathematics. This theorem is used to describe the relationship between the lengths of the sides of a right triangle.
Pythagorean Theorem
In a right triangle:
a and b are the lengths of the legs (the two sides that form the right angle).
c is the length of the hypotenuse (the side opposite the right angle).
The theorem states that the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides:
a² + b² = c²
This can also be expressed as c = √(a² + b²).
For example, if one leg of the triangle is 3 units and the other leg is 4 units, you can find the hypotenuse as follows:
3² + 4² = c²9 + 16 = 25c = √25 = 5Question:
what does a^2+b^2=C^2 formula mean ?

In this fulcrum, the weights are perfectly balanced. How far must the fulcrum be located from the 60 pound weight if the bar is 24 feet long?
A) 9
B) 15
C) 12
Answer:
15 feet
Step-by-step explanation:
Given : In this fulcrum, the weights are perfectly balanced.
To Find: How far must the fulcrum be located from the 60 pound weight if the bar is 24 feet long?
Solution:
To make the weights perfectly balanced torque must be equal
[tex]Torque = Force \times d[/tex]
Where [tex]Force = Mass \times Acceleration[/tex]
Let a be the acceleration
d= Distance between the pivot and the acting point.
Let x be the distance from 60 pound weight where fulcrum is located
Since we are given that Length of bar = 24 feet.
So,Distance of fulcrum from 100 pound weight = 24-x
Now torque for 60 pound weight :
[tex]Torque = 60a \times x[/tex]
Now torque for 100 pound weight.
[tex]Torque =100a \times (24-x)[/tex]
Now to maintain the equilibrium i.e. To make the weights perfectly balanced
[tex]60a \times x =100a \times (24-x)[/tex]
[tex]60x = 2400-100x[/tex]
[tex]160x = 2400[/tex]
[tex]x = \frac{2400}{160}[/tex]
[tex]x = 15[/tex]
Hence The fulcrum must be located 15 feet from the 60 pound weight if the bar is 24 feet long.
