What is the slope given points 3/5 and (- 2 4?
The slope of the points (3, -5) and (-2, 4) is -9/5.
Slope in general term means that the elevation or the steepness of any curve. We use slope in order to find the equation of the line between two points. The formula for finding the slope between two points (x₁, y₁) and (x₂, y₂) is expressed as
m = (y₂ - y₁)/(x₂ - x₁)
where m is the slope between the points, y₂ - y₁ is difference between the y coordinates and x₂ - x₁ is the difference between the x coordinates for the same y coordinates.
We have (x₁, y₁) = (3, -5) and (x₂, y₂) = (-2, 4)
So, the slope will be
m = (4 + 5)/(-2 -3)
m = 9/(-5)
m = -9/5 which is the required slope.

Challenge: Using the 2 functions shown, circle the choice that must be true. Show your work!
The choice that is true are:
f(0) > g(0)
f(6) = g(12)
f(-4) = g(-4)
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
f(x) = 4x + 2
g(x) = (5/2)x - 4
Now,
f(0) = 2
g(0) = -4
f(0) > g(0)
f(6) = 24 + 2 = 26
g(12) = (5/2) x 12 - 4 = 30 - 4 = 26
f(6) = g(12)
f(-4) = -16 + 2 = -14
g(-4) = -10 - 4 = -14
f(-4) = g(-4)
f(2) = 8 + 2= 10
g(2) = 1
f(2) > g(2)
Thus,
f(0) > g(0) is true
f(6) = g(12) is true
f(-4) = g(-4) is true
g(2) > f(2) is not true

julio invests 5360 in a retirement account with a fixed annual interest rate of 4% compounded 4 times per year. What will the account balance be after 17 years?
Answer:
To find the account balance after 17 years, we need to first calculate the annual interest rate. Since the interest is compounded 4 times per year, the effective annual interest rate is equal to (1 + 0.04/4)^4 - 1, which is about 4.169%.
To find the account balance after 17 years, we can use the formula for compound interest: A = P(1 + r/n)^(nt), where A is the final amount, P is the initial principal, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years. Plugging in the values we know, we get:
A = 5360(1 + 0.04169/4)^(4*17)
A = $9,907.35
So the account balance after 17 years will be about $9,907.35.
is referred to as "energy possessed by an object as a result of its MOTION".
Group of answer choices?
Kinetic Energy is referred to as "energy possessed by an object as a result of its MOTION".
What is Kinetic Energy?
The energy that an item or particle has as a result of its motion is known as kinetic energy. An object accelerates and gains kinetic energy when work—the transfer of energy—is done on it by exerting a net force.
An object in motion always has a velocity, or "v," at any given moment. This energy is referred to as "kinetic energy," and it comes from:
Kinetic Energy = 12×m×v2
Here, m = Mass of the object in motion
Kinetic energy is a type of power that a moving object or particle possesses. An item accumulates kinetic energy when work, which involves the transfer of energy, is done on it by exerting a net force. A moving object or particle has kinetic energy, which depends on both its mass and its rate of motion. The type of motion can be vibration, rotation on an axis, translation (or travel along a path from one place to another), or any combination of these.
A body's translational kinetic energy is equal to 1/2mv2, which is the product of its mass, m, and square of its velocity, v.

which type of variable does not change during an experiment, and serves as a comparison point for all data points?
Control variables are the type of variable that does not change during an experiment, and serves as a comparison point for all data points.
Control variables are also called constant variables or control variables.
A control variable in an experiment is a variable that is held constant or controlled by the researcher.
A control variable is a variable or item that the researcher wants to keep constant throughout the study so as not to affect the results.
A typical study design measures the influence of an independent variable on the dependent variable. In order for this to be done properly, it is important to control another external or standardized variable. Experimentation is not as simple as changing factors and recording results. In practice, any study has many different factors that can affect its results. A control variable is a way to keep some of these factors constant so that comparisons are unbiased and transparent.
In many experiments, even slight variations in some factors can lead to inaccurate or skewed results. Voxco's Experimental Research Toolkit aims to give researchers greater control over variables to help them achieve the results they want.

Jamie swims 1/2 of the length of the swimming pool every 1/4 of a minute
Answer:
Jamie swims 1/2 the length of the swimming pool every 1/4 of a minute. This means that Jamie swims 1/8 of the length of the pool in one second. If the pool is 25 meters long, it would take Jamie 200 seconds, or about 3 minutes and 20 seconds, to swim the length of the pool. This is just an estimation, as the actual time it would take Jamie to swim the length of the pool would depend on factors such as Jamie's swimming ability and the speed at which they swim.

For what values of x is the expression below defined?
√x+5+√1-x
A. -5
OB. 5> x≤-1
C. 5>x>1
D. 5≤x≤1
Answer:
The expression √x+5+√1-x is defined for all values of x such that the value under the square root sign is non-negative. We can find the values of x that satisfy this condition by considering each of the square roots separately.
For the first square root, the value under the square root must be non-negative, so we have the following inequality:
x + 5 ≥ 0
x ≥ -5
For the second square root, the value under the square root must be non-negative, so we have the following inequality:
1 - x ≥ 0
x ≤ 1
Therefore, the expression is defined for all values of x that satisfy both of these inequalities. This means that the expression is defined for values of x in the range -5 ≤ x ≤ 1. The correct answer is therefore option D.

If the car goes to the top of spike's peak and back, the mileage of the car is 16 miles per gallon
The mileage of car in uphill = 12 miles per gallon
The mileage of car in downhill = 24 miles per gallon
The total distance traveled in up hill = 48 miles
The number of gallon of gas used = 48/12
= 4 gallon
The total distance traveled in down hill = 48 miles
The number of gallon of gas used = 48 / 24
= 2 gallon
Total distance traveled = 48 + 48
= 96 miles
Total number of gallons of gas = 4 + 2
= 6 gallon
The mileage = Total distance / The number of gallon
= 96 / 6
