the product of 2.5 and t. to a algebraic expressions
To an algebraic expression, the product of 2.5 and t is 2.5*t=2.5t.
An algebraic equation is what?In mathematics, an expression that incorporates variables, constants, and algebraic operations is known as an algebraic expression (addition, subtraction, etc.).
Terms comprise expressions.
As said, "The word product" refers to the result of a multiplication.
To find out which two integers are multiplied together, look for the term "AND." The result of adding 2 and 3 is 6
The two numbers being multiplied in this example are 2.5 and an unidentified number, only called t.
The formula is 2.5*t
= 2.5t.
We are at our limit at this point. Since the solution has not been provided, we are unable to write an equation.

Use additive inverse and their properties to find equivalent expressions 3+(-5)
The additive inverse of the given mathematical operation 3+(-5) is 2.
What is additive inverse?An additive inverse of a number is defined as the value that results in zero when added to the original number. It is the value we add to a number in order to get zero. If an is the original number, then its additive inverse is minus a, i.e., -a, such that a+(-a) = a - a = 0. 2 2 is the additive inverse of -2.So, 3+(-5):
3+(-5)-2Then, add 2 as follows:

A car is driving at 45 kilometers per hour. How far, in meters, does it travel in 5 seconds?
The car travels 62.5 meters in 5 seconds
How to calculate the distance the car travelled ?
The car is driving at 45 kilometres per hour
The first step is to convert kilometres to meters
1 km= 1000 meters
= 45×1000
= 45,000
The next step is to convert hours to seconds
1 hour= 3600 seconds
= 45000/3600
= 12.5
The distance travelled in 5 seconds can be calculated as follows
= 12.5 × 5
= 62.5
Hence the distance travelled in 5 seconds is 62.5 meters

The value of h(-2) is 65
What is a function?A function can be defined as an expression, law , rule of hypothesis that explains or compares the relationship between two variables - the dependent and the independent variable.
Given the function;
h(x) = 2x^4 - x³ + 2x² - 7x + 3
To determine the function, h(-2)
We substitute the value of x as -2 into the function, we have;
h(-2) = 2(-2)^4 - (-2)^3 + 2(-2)^2 - 7(-2) + 3
expand the bracket
h(-2) = 2(16) - 2(-8) - 7(-2) + 3
h(-2) = 32 + 16 + 14 + 3
h(-2)= 65

The displacement (in meters) of a particle moving in a straight line is given by s=6t^3+1t+4 where t is measured in seconds.
Find the velocity of the particle at the times given.
Velocity at time t=1, t=2, t=3, and t=a
Answer:
Velocities
t = 1 : 11 m/s
t = 2 : 27m/s
t = 3: 56.33 m/s
t = a: 6a + 1 + 4/a m/s
Step-by-step explanation:
s(t) = 6t³ + 1t + 4 where s = displacement in meters and t is time in seconds
s(t) = v(t). t where v is the velocity in m/s and t is time in seconds
So v = s/t
At time t = 1
s(1) = 6 x 1³ + 1 x 1 + 4 = 6 + 1 + 4 = 11 meters
v(1) = 11/1 = 11 m/s
At time t = 2
s(2) = 6 x 2³ + 1 x 2 + 4 = 6 x 8 + 2 + 4 = 48+ 2 + 4 = 54 m
v(2) = 54 /2 = 27m/s
At time t = 3
s(3) = 6 x 3³ + 1 x 3 + 5 = 6 x 27 + 3 + 4 = 169 m
v(3) = 169/3 = 56.33 m/s
At time t = a
s(a) = 6a³ + 1a + 4 = 6a³ + a + 4
v(a) = s(a)/a = (6a³ + a + 4)/a = 6a + 1 + 4/a m/s

How do I simplify +(-11) I am just saying this to add letters
+(-11) is -11. You're "adding" -11 when in reality you're taking away 11 unless:
the equation looks like: -6+(-11)
the answer would be -17 because you're adding a negative to a negative. Taking away from a negative number is simply moving further down the negative number line, which makes the negative numbers "increase" in value
But if an equation looks like: 6+(-11)
the answer would be -5 since you are taking away 11 from a positive number.

Answer:
83.5
Step-by-step explanation:
Median means middle. So in order to get that you need to write the numbers in order and then get the middle number. If the amount of numbers are even then take the 2 middle ones and add the together then divide by two.
89, 52, 78, 92, 98, 64 --> 52, 64, 78, 89, 92, 98
Since you have 2 middle numbers, you must take the middle 2 (78 and 89) and add them.
78 + 89 = 167
Now divide 167 by 2
167 / 2 = 83.5

Five pulse rates are randomly selected from a set of measurements. The five pulse rates have a mean of 74.6 beats per minute. Four of the pulse rates are
81, 54, 77, and 68.
a. Find the missing value.
b. Suppose that you need to create a list of n values that have a specific known mean. Some of the n values can be freely selected. How many of the n
values can be freely assigned before the remaining values are determined? (The result is referred to as the number of degrees of freedom.)
Part (a)
x = the missing value
The set is {81, 54, 77, 68, x}
Add up those values and divide by 5 to compute the mean. Set this equal to the 74.6 stated. Then solve for x like so:
(81+54+77+68+x)/5 = 74.6
(280+x)/5 = 74.6
280+x = 5*74.6
280+x = 373
x = 373-280
x = 93
Answer: The missing value is 93========================================================
Part (b)
In the previous part, we have n = 5 values and n-1 = 5-1 = 4 of them can be freely selected. The 5th final value is locked in based on what those previous four values are. That 5th value being x mentioned earlier.
This shows that the degrees of freedom is n-1

What is an equation?An equation is formed by joining two expressions with the equal sign "=". The two expressions on either side of the equals sign are referred to as the "left-hand side" and "right-hand side" of the equation.
Typically, the right-hand side of an equation is assumed to be zero. This does not reduce generality because we can balance it by subtracting the expression on the right-hand side from the expressions on both sides.
We have given 12y - 1 / 2 = 8y + 8 / 5
