Answer:
y-intercept = -17/3x-intercept = 17/4Step-by-step explanation:
4x - 3y = 17
y-intercept is for x = 0.
x-intercept is for y = 0.
y-intercept:
put x = 0 to the equation
4(0) - 3y = 17
0 - 3y = 17
-3y = 17 divide both sides by (-3)
y = - 17/3
x-intercept:
put y = 0 to the equation
4x - 3(0) = 17
4x - 0 = 17
4x = 17 divide both sides by 4
x = 17/4

Terrence buys a new car for $20,000. The value of the car depreciates by 15% each year. If f(x) represents the value of the car
after x years, which function represents the car's value?
f(x) = 20,000(0.85)*
f(x) = 20,000(0.15)*
f(x) = 20,000(1.15)
f(x) = 20,000(1.85)
Answer:
f(x) = 20,000(0.85)*
Step-by-step explanation:
Answer: [tex]f(x)=20,000(0.85)^x[/tex]
Step-by-step explanation:
We know that the exponential decay (depreciation) equation with rate of decay r in time period x is given by :-
[tex]f(x)=A(1-r)^x[/tex], A is the initial value .
Given: The initial value of truck = $20,000
Rate of depreciation= 15% = 0.15
Now, the function represents the car's value after x years is given by ;-
[tex]f(x)=20,000(1-0.15)^x\\\\\Rightarrow\ f(x)=20,000(0.85)^x[/tex]

Answer:
Yes. It's a right triangle.Step-by-step explanation:
If a ≤ b < c are the length of the sides of a right triangle, then
a² + b² = c².
We have:
a =30 ft, b = 40 ft and c = 50 ft.
Check the equality:
L = 30² + 40² = 900 + 1600 = 2500
R = 50² = 2500
L = R
Find p(2)
Find p(2 or fewer)
Answer:
P(2)=0.021942 approximately
P(2 or fewer)=0.02711 approximately
Step-by-step explanation:
[tex] P(x)=(n choose x) *p^x * q^{n-x} [/tex]
x is the number of successes desired
p is probability of getting a success per trial
n is the number of trials
q is 1-p
So n=15 and p=.4 here
And you want to know P(2) which means x is 2
Plug in this information
[tex] P(2)=(15 \text{ choose } 2) *.4^2 * .6^{15-2} [/tex]
Just plug into calculator... P(2)=0.021942 approximately
For p(2 or fewer) you just do P(0)+P(1)+P(2)
I already found P(2)
You need to find P(1)
Once you get P(1), add that result to 0.021942.
Try to do part b and I will tell you if you got it right or not.
So P(2 or less) is P(0)+P(1)+P(2)
So to complete this we need to find P(1) and almost forgot P(0)...
We already have P(2).
P(0)=(15 choose 0) *.4^0*.6^(15-0)=0.00047
P(1)=(15 choose 1) *.4^1 *.6^(15-1)=.004702
Now P(2)=0.021942
--------------------------add these
0.027114 approximately
Gavin is analyzing the success of a newly launched game app. The game takes place on an island that's been overrun with zombies. When a player is on level one of the game, the population of zombies is 50,000. Each time the player advances to a new level, that population grows at a rate of 5%. Answer the questions that follow to continue Gavin’s analysis.
Gavin's analysis of a game's zombie population growth involves understanding the concept of exponential growth, characterized by a fixed percentage increase over time, and the eventual transition to logistic growth as resources become limited.
Explanation:The scenario presented involves an analysis of exponential growth, which is a typical mathematical concept found within algebra and applied mathematics.
Gavin's analysis of the game app, which features a starting zombie population of 50,000 that grows at a rate of 5% per level, allows us to examine how the population changes as players advance through the levels.
Exponential growth is characterized by a constant rate of growth applied to a continuously growing base over time.
In the case of the example town mentioned, we learn that exponential growth can lead to doubling populations and that the rule of 70 is a shortcut to estimate the number of years required for a population to double at a constant growth rate.
Specifically, if the town's population doubles every 10 years, this implies a growth rate of approximately 7% per year since 70 divided by the growth rate (7) equals the doubling time (10 years).
However, such unchecked exponential growth will eventually transition to logistic growth, especially when resources become limited, thus limiting the population size to a maximum capacity, known as carrying capacity.
In biology, this logistic growth curve begins with an exponential phase, followed by a slowdown, and eventually levels off at the carrying capacity.
Final answer:
The subject of this question is Mathematics and the grade is High School. Gavin is analyzing the success of a newly launched game app. The game takes place on an island that's been overrun with zombies. Each time a player advances to a new level, the population of zombies grows at a rate of 5%.
Explanation:
The subject of this question is Mathematics and the grade is High School.
In this question, Gavin is analyzing the success of a newly launched game app. The game takes place on an island that's been overrun with zombies. When a player is on level one of the game, the population of zombies is 50,000. Each time the player advances to a new level, that population grows at a rate of 5%.
To calculate the population of zombies at each level, we can use the formula:
The population of zombies at level one: 50,000The population of zombies at level two: 50,000 x 1.05 = 52,500The population of zombies at level three: 52,500 x 1.05 = 55,125And so on...By using this exponential growth formula, Gavin can analyze the growth of the zombie population as players advance through the levels of the game.

In the diagram, a circle centered at the origin, a right triangle, and the Pythagorean theorem are used to derive the equation of a circle, x2 + y2 = r2. If the center of the circle were moved from the origin to the point (h, k) and point P at (x, y) remains on the edge of the circle, which could represent the equation of the new circle? (h + x)2 + (k + y)2 = r2 (x – h)2 + (y – k)2 = r2 (k + x)2 + (h + y)2 = r2 (x – k)2 + (y – h)2 = r2
Answer:
(x – h)2 + (y – k)2 = r2
Step-by-step explanation:
If the center of the circle were moved from the origin to the point (h, k) and point P at (x, y) remains on the edge of the circle the equation of the new circle
(x – h)2 + (y – k)2 = r2
Based on Pythagorean theorem, and the location of the center of the
circle, (h, k), the equation of the circle is represented by the option;
(x - h)² + (y - k)² = r²How can the equation of the circle be found?
The general form of the equation of the circle is (x - h)² + (y - k)² = r²
Where;
(h, k) = The center of the circle
r = The radius of the circle
A description of the equation of the circle is as follows;
With regard to a location on the edge (circumference), of the circle, (x, y),
where, the center of the circle is (h, k), by Pythagorean the sum of the
square of the length of the horizontal side, (x - h), and the square of the
vertical side (y - k), of the right triangle formed gives the square of the
radius of the circle.
Therefore, the equation of the new circle can be represented by the equation;
(x - h)² + (y - k)² = r²The above equation is the general form of the equation of a circle.

Lorne subtracted 6x3 – 2x + 3 from –3x3 + 5x2 + 4x – 7. Use the drop-down menus to identify the steps Lorne used to find the difference.
Final answer:
Lorne subtracted the polynomial 6x³ − 2x + 3 from − 3x³ + 5x² + 4x − 7 by changing the signs of the second polynomial and combining like terms, resulting in the difference − 9x³ + 5x² + 6x − 10.
Explanation:
To find the difference between two polynomials, we subtract the corresponding terms of the second polynomial from the corresponding terms of the first. In the given problem, Lorne subtracted 6x³ − 2x + 3 from − 3x³ + 5x² + 4x − 7. To do this, we change the signs of the polynomial being subtracted and then combine like terms.
First, we write the problem with the second polynomial's signs changed: − 3x³ + 5x² + 4x − 7 - (6x³ − 2x + 3).
Next, we distribute the negative sign: − 3x³ + 5x² + 4x − 7 - 6x³ + 2x - 3.
Finally, we combine like terms: (− 3x³ − 6x³) + (5x²) + (4x + 2x) + (− 7 − 3).
The resulting difference is − 9x³ + 5x² + 6x − 10.

Please Answer!!! how do the graphs of (x) = x^2 and g (x)= 3/4 x^2? relate?
a. the graph of g(x) is the graph of f(x) compressed horizontally by a factor of 3/4
b. the graph of g(x) is the graph of f(x) compressed vertically by a factor of 3/4
c. the graph of g(x) is the graph of f(x) compressed vertically by a factor of 4/3
d. the graph of g(x) is the graph of f(x) compressed horizontally by a factor of 4/3
Answer:
The correct option is B.
Step-by-step explanation:
The given functions are
[tex]f(x)=x^2[/tex]
[tex]g(x)=\frac{3}{4}x^2[/tex]
It can be written as
[tex]g(x)=\frac{3}{4}f(x)[/tex] .... (1)
The vertical stretch and compression is defined as
[tex]g(x)=kf(x)[/tex] .... (2)
If k>1, then it represents vertical stretch by factor a.
If 0<k<1, then it represents vertical compression by factor a.
From (1) and (2), we get
[tex]k=\frac{3}{4}[/tex]
Since k<1, therefore he graph of g(x) is the graph of f(x) compressed vertically by a factor of 3/4.
Hence the correct option is B.

You are helping with some repairs at home. You drop a hammer and it hits the
floor at a speed of 8 feet per second. If the acceleration due to gravity (g) is
32 feet/second, how far above the ground (h) was the hammer when you
dropped it? Use the formula:
V = 2gh
Answer:
1 foot.
Step-by-step explanation
That is not the correct formula. Correct is V^2 = 2gh where h = the height
so the equation is:
8^2 = 2*32* h
h = 64/ 64 = 1 foot.
Answer:
[tex]h=\frac{1}{8} feet[/tex]
Step-by-step explanation:
In order to be able to solve this problem you just have to clear the formula for height:
V=2gh
[tex]\frac{V}{2g}=H[/tex]
[tex]\frac{8}{64}=H[/tex]
[tex]\frac{1}{8}=H[/tex]
So the height from which the hammer is dropped is 1/8 feet.
