Write an inequality that represents `t`, the number of hours past midnight, when the temperature was colder than -4 degrees Celsius. Explain or show your reasoning
Question:
At midnight, the temperature in a city was 5 degrees Celsius. The temperature was dropping at a steady rate of 2 degrees Celsius per hour.
Write an inequality that represents t, the number of hours past midnight, when the temperature was colder than -4 degrees Celsius. Explain or show your reasoning.
Answer:
[tex]t > 4.5[/tex]
Step-by-step explanation:
Given
Let T = temperature and t = hours past midnight
So, we have:
[tex](t_1,T_1) = (0,5)[/tex] --- at midnight
[tex]m = -2[/tex] --- rate (it is negative because the temperature drops)
Required
Determine the inequality when the temperature is colder than -4 degrees
First, we calculate the hours when the temperature at -4 degrees
This is represented as:
[tex](t_2,T_2) = (t,-4)[/tex]
[tex](t_1,x_1) = (0,5)[/tex]
Using the slope formula, we have:
[tex]m = \frac{T_2 -T_1}{t_2 - t_1}[/tex]
[tex]-2 = \frac{-4-5}{t -0}[/tex]
[tex]-2 = \frac{-9}{t}[/tex]
Solve for t
[tex]t = \frac{-9}{-2}[/tex]
[tex]t = 4.5[/tex]
This implies that: at 4.5 hours, the temperature is at -4 degrees Celsius.
So, the inequality is:
[tex]t > 4.5[/tex]

3 1/5 divided by 1 1/2
Answer:
2.13333333333
Step-by-step explanation:
First you do 5x3+1 = 16/5
Second, you do 2x1+1 = 3/2
Third, you divided 16/5 by 3/2.
4x+12+3x+7x(3+5)+6=90
solve for x
Answer:
4x+12+3x+7x(3+5)+6=90
Combine like terms.
4x+12+3x+56x+6=90
63x+18=90
63 x = 72
x = 72/63
x = 8/7

Step-by-step explanation:
Laura wants to cover a box with fabric.
• The box is in the shape of a rectangular prism.
• It measures 15 in. long, 11 in. wide, and 24 in. tall.
Answer:
Area of rectangular prism = 1,578 inch²
Step-by-step explanation:
Given:
Length of rectangular prism = 15 in
Width of rectangular prism = 11 in
Height of rectangular prism = 24 in
Find:
Total fabric need
Computation:
Total fabric need = Area of rectangular prism
Area of rectangular prism = 2[lb + bh + hl]
Area of rectangular prism = 2[(15)(11) + (11)(24) + (24)(15)]
Area of rectangular prism = 2[165 +264 + 360]
Area of rectangular prism = 2[789]
Area of rectangular prism = 1,578 inch²

take the derivative of the equation 4 times. f 4 (x)=0.
Step-by-step explanation:
if you put in the values (-1/2, 1/4, 2/5) in the function
{–8, –2, 18}
Step-by-step explanation:
y = 5x − 2
x = −1.2 > y = 5(−1.2) − 2 = −6 − 2 = −8
x = 0 > y = 5(0) − 2 = 0 − 2 = −2
x = 4 > y = 5(4) − 2 = 20 − 2 = 18
{-1/2, 1/4, 2/5}
Step-by-step explanation:
All you have to do is go on a graphic calculator and input the equation by pressing y= then after putting it in to y= all you have to do is press 2nd (the only blue button) and graph and that will show you all the points to that equation (also known as range and domain)
Hope this helps. :)
Domain is inputs, input the domain for x
y=5(-1.2)-2
y=-6-2
y=-8
y=5(0)-2
y=0-2
y=-2
y=5(4)-2
y=20-2
y=18
range is {-8, -2, 18}
For x = 0,
we substitute zero into the equation to find its y value like so:
y = 5x-2
y = 5(0)-2
y = -2
There you go.
Take the derivative of the equation 4 times. f 4 (x)=0.
Y = 5x – 2
domain. {–5, –1, 0, 2, 10}
x = -5 then y = 5(-5) – 2 = -27
x = -1 then y = 5(-1) – 2 = -7
x = 0 then y = 5(0) – 2 = -2
x = 2 then y = 5(2) – 2 = 8
x = 10 then y = 5(10) – 2 = 48
answer
{–27, –7, –2, 8, 48}

Find the area of each circle. Use 3.14 for the value of pi. Round your answer to the nearest tenth. Do NOT include units in your answer (ie. ft, in, km, etc.) (FR)
Answer:
12.6
Step-by-step explanation:
The equation for a circle's area is [tex]A=\pi r^2[/tex].
We can use this equation to end up with A=(3.14)4
And 3.14 times 4 is 12.56.
Then we have to round to the nearest tenth.
Therefore your answer is 12.6

Please help I am struggling so bad
9514 1404 393
Answer:
3.14 units
Step-by-step explanation:
The formula for the length of an arc is ...
s = rθ
where r is the radius of the circle, and θ is the central angle in radians.
__
The relationship between degrees and radians is ...
180° = π radians
If we divide this equation by 3, we see ...
60° = π/3 radians
__
The radius is given as 3 units, so the arc length is ...
s = (3 units)(π/3) = π units
The arc length is 3.14 units.

ABCD is a parallelogram. If a CDA - 57 then BCD-_?
The diagram is not to scale.
133
57
114
123
Answer:
57
Step-by-step explanation:
It is given in the question that length CDA = 57.
Since the shape is a parallelogram, then we know that length AD=BC and AB=CD.
CDA = CD + AD
BCD = BC + CD
Since BC=AD and CD=CD
BCD = BC + CD is the same as CD + AD = CDA
Therefore BCD is the same length as CDA = 57
In other words, CDA is made up of a long side and a short side = 57
BCD is also made up of a long side and a short side, and since the longs sides are equal to each other and the short sides are also equal to each other in a parallelogram, BCD is the same length as CDA = 57.
Hope this helped!

Answer:
x = 42
y = 38.
I'm pretty sure this is the answer
Answer: x=42 y=48
Step-by-step explanation:
The angle with 42° and the blank space should add up to 90° so you would have to do 90-42=48° to find the blank space. As opposite angles are equal that means y=48° too.
Then to find out what x is you have to do 90-48=42° as the part with x and y in it has to add up to 90°.
You can check this by checking the two quarters. They should both add up to 90°.
42+48=90°
48+42=90°
So we know its correct.
Hope this helps :)
