The outside temperature was 73°f at 1.p.m and decreases at a rate of 1.5°f each hour. What expression can be used to determine the temperature h(h is the variable) hours after 1.p.m?
The expression to represent the temperature 'h' hours after 1 p.m. given an initial temperature of 73°F and a decrease rate of 1.5°F per hour is 73 - 1.5h. This allows us to calculate the temperature at any given hour where 'h' is the number of hours after 1 p.m.
Explanation:The problem involves dealing with linear equations, specifically those representing changes over time. In this situation, the temperature starts at 73°F at beginning of the time, i.e., at 1 pm and then decreases at a steady rate of 1.5°F per hour.
So, the decrease in temperature can be represented by 1.5h, where h is the number of hours elapsed since 1 p.m. As the temperature starts at 73°f, we subtract this decrease from the initial temperature. Therefore, the expression to determine the temperature after h hours is 73 - 1.5h.
This equation tells us that for each hour after 1 p.m., we simply subtract 1.5 from 73 and this would give the temperature at that time. For example, at 2 p.m., h equals 1, and the equation 73 - 1.5(1) gives us 71.5°F.

Factor completely 16a^3b^7 + 2a^6b^4 − 22a^4b^5.
Answer:
[tex]2 a^3 b^4 (a^3 - 11 a b + 8 b^3)[/tex]
Step-by-step explanation:
The given expression is
[tex]16a^3b^7 + 2a^6b^4 -22a^4b^5[/tex]
We need to find the factored form of the given expression.
In the given expression [tex]2 a^3 b^4[/tex] is the greatest common factor of all terms.
Taking GCF we get.
[tex]2 a^3 b^4 (8 b^3+a^3 - 11 a b)[/tex]
In can be written as
[tex]2 a^3 b^4 (a^3 - 11 a b + 8 b^3)[/tex]
This expression is the complete factored form of the given expression because [tex]a^3 - 11 a b + 8 b^3[/tex] can not be factored further.
Therefore, the factor form of given expression is [tex]2 a^3 b^4 (a^3 - 11 a b + 8 b^3)[/tex].
Which of the following represents the zeros of f(x) = 2x3 − 5x2 − 28x + 15?
5, −3, −1 over 2
5, −3, 1 over 2
5, 3, −1 over 2
5, 3, 1 over 2
Answer: B) 5, −3, 1 over 2 are the zeros of f(x).
Step-by-step explanation:
Given function f(x)=[tex]2x^3-5x^2-28x+15[/tex]
If a is a zero of f(x) then f(a)=0
Let's check all the options
[tex]f(5)=2(5)^3-5(5)^2-28(5)+15\\=2(125)-5(25)-28(5)+15=250-125-140+15=0[/tex]
[tex]f(-3)=2(-3)^3-5(-3)^2-28(-3)+15\\=2(-27)-5(9)-28(-3)+15=-54-45+84+15=0[/tex]
[tex]f(\frac{-1}{2})=2\frac{-1}{2}()^3-5(\frac{-1}{2})^2-28(\frac{-1}{2})+15\\=2(\frac{-1}{8})-5(\frac{-1}{4})+14+15=\frac{-1}{4}-\frac{5}{4}+29=\frac{110}{4}=\frac{55}{2}\neq 0[/tex]
Therefore , 5 and -3 are zeroes of f(x).but -1/2 is not.
[tex]f(\frac{1}{2})=2\frac{1}{2}()^3-5(\frac{1}{2})^2-28(\frac{1}{2})+15\\=2(\frac{1}{8})-5(\frac{1}{4})-14+15=\frac{1}{4}-\frac{5}{4}-14+15=0[/tex]
⇒ 1/2 isthe third zero of f(x).
Here we got our three zeroes as 5,-3,1/2,rest other will not satisfy f(a)=0
Therefore B represents the zeroes of f(x).

Paul's family drove 377 mi to the beach averaging 58 mi/h on the way there. On the return trip home, they averaged 65 mi/h .
What was the total time Paul's family spent driving to and from the beach?
Total time driving to and from beach: 12.3 hours; averaging 58 mph there, 65 mph returning home.
To find the total time Paul's family spent driving to and from the beach, we can calculate the time for each leg of the trip and then add them together.
1. Time taken for the trip to the beach:
[tex]\[ \text{Time}_1 = \frac{\text{Distance}_1}{\text{Speed}_1} \][/tex]
2. Time taken for the return trip:
[tex]\[ \text{Time}_2 = \frac{\text{Distance}_2}{\text{Speed}_2} \][/tex]
Given:
[tex]- Distance to the beach, \( \text{Distance}_1 = 377 \) miles\\- Speed to the beach, \( \text{Speed}_1 = 58 \) mph\\- Speed returning home, \( \text{Speed}_2 = 65 \) mph[/tex]
Let's calculate:
[tex]1. \[ \text{Time}_1 = \frac{377}{58} \][/tex]
[tex]2. \[ \text{Time}_2 = \frac{377}{65} \][/tex]
Now, let's compute:
[tex]\[ \text{Time}_1 = \frac{377}{58} \approx 6.5 \text{ hours} \]\[ \text{Time}_2 = \frac{377}{65} \approx 5.8 \text{ hours} \][/tex]
Finally, to find the total time spent driving to and from the beach, we add these times:
[tex]\[ \text{Total time} = \text{Time}_1 + \text{Time}_2 \]\[ \text{Total time} \approx 6.5 + 5.8 \]\[ \text{Total time} \approx 12.3 \text{ hours} \][/tex]
So, Paul's family spent approximately 12.3 hours driving to and from the beach.

Find the equation of a line that intersects with y=2x-1 on the y-axis and is parallel to y=-x.
Please explain.
The equation of the required line is: y=-x-1.
y=2x-1 is in slope intercept form. So the y-intercept = -1.
Given that the line intersects with y=2x-1 on the y-axis. It means the required line also has y-intercpt =b= -1.
Given that: The line is parallel to y=-x.
The slope of y=-x is -1. By comparing with y=mx+b.
Since the lines are parallel. So the required line will also have slope = m= -1.
So the equation of the required line is: y=mx+b or y = -1x + (-1) or y=-x-1.
