Answer:
3 hours
Step-by-step explanation:
The temperature in Juneau, Alaska at noon was -8 degrees Celsius. By 1 PM, the temperature increased by 10 degrees. Draw a number line to represent the situation and determine the temperature at 1 PM.
Answer:
2 degrees
Step-by-step explanation:
1) The temperature at 12:00 PM was -8 degrees celsius
2) The temperature at 1:00 PM was 10 degrees higher than at 12:00 PM
3) -8 + 10 = 2
4) The temperature at 1:00 PM was 2 degrees celsius
5) Draw a number line with the labels 12:00 PM and 1:00 PM on either end
6) Label above 12:00 PM -8 degrees celsius, and above 1:00 PM 2 degrees celsius
7) Draw an arrow pointing from 12:00 PM towards 1:00 PM to show that the temperature changes between 12:00 PM and 1:00 PM

19, 12, 3, 6, 18, 20, 4, 4, 8, 12, 16, 20, 10, 1, 7, 8 1. Find the range of the data
Answer:
The highest observation =20
The lowest observation = 1
Range of the data = 20-1
= 19(ans)
Answer:
The range is 19
Step-by-step explanation:
To calculate the range of a set of data, you order the numbers from highest to lowest (ex; 20,20,19,18,16,12,12,10,8,8,7,6,4,4,3,1,1) then you subtract the highest number from the lowest number (ex; 20 - 1)
Write the slope intercept form of the equation of the line passing through (-4,6) and perpendicular to y=-2x-5.
Answer:
[tex]y=\frac{1}{2} x+8[/tex]
Step-by-step explanation:
Hi there!
Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)
1) Determine the slope (m)
Perpendicular lines will always have slopes that are negative reciprocals of each other. For example, two perpendicular lines might have slopes of 3 and -1/3.
After observing the equation y=-2x-5, we can conclude that the slope is -2. Therefore, a line perpendicular to this line would have a slope of 1/2. Plug this into [tex]y=mx+b[/tex]:
[tex]y=\frac{1}{2} x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=\frac{1}{2} x+b[/tex]
Plug in the given point (-4,6)
[tex]6=\frac{1}{2}(-4)+b\\6=-2+b[/tex]
Add 2 to both sides
[tex]6+2=-2+b+2\\8=b[/tex]
Therefore, the y-intercept is 8. Plug this back into [tex]y=\frac{1}{2} x+b[/tex]:
[tex]y=\frac{1}{2} x+8[/tex]

f(x) = x2. What is g(x)?
f(x) = x2
-5
5
g(x)/5
O A. g(x) = -x - 3
O B. g(x) = x2 - 3
O c. g(x) = -x2
D. g(x) = -382
If function f(x)= x² then g(x) is -x² - 3 , option A is correct.
What is a function?A relation is a function if it has only One y-value for each x-value.
The reflection in the x-axis changes the sign of the y-coordinate. So, the reflection of f(x) = x² in the x-axis is g(x) = -x².
Secondly, the downward shift of 3 units means subtracting 3 from the y-coordinate.
So, the transformation applied to f(x) to get g(x) is reflection in the x-axis followed by a downward shift of 3 units.
g(x) = -x² - 3 is the result of applying a reflection in the x-axis followed by a downward shift of 3 units to the function f(x) = x².
Hence, if function f(x)= x² then g(x) is -x² - 3 , option A is correct.

Find the volume. Use pi as part of the equation. Round to the nearest 10th
Answer:
301.4 ft.
Step-by-step explanation:
The radius of this circle is 4; the height of this circle is 6.
Using the formula, πr²h, we can plug-in the unknown values.
In the formula, 'r' means radius, 'h' means height, 'π' means pi. 3.14 is often a substitute for pi.
πr²h - π4² · 6 = 301.44.
301.44 rounded to the nearest tenth is 301.4.
Therefore, the volume of this cylinder is 301.4 ft.

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary).
16, 80,400,...
16,80,400,...
\text{Find the 6th term.}
Find the 6th term.
Given:
The sequence is:
[tex]16,80,400,...[/tex]
To find:
The 6th term of the given sequence.
Solution:
We have,
[tex]16,80,400,...[/tex]
Here, the first term is:
[tex]a=16[/tex]
The ratio between consecutive terms are:
[tex]\dfrac{80}{16}=5[/tex]
[tex]\dfrac{400}{80}=5[/tex]
The given sequence has a common ratio 5. So, the given sequence is a geometric sequence.
The nth term of a geometric sequence is:
[tex]a_n=a(r)^{n-1}[/tex]
Where, a is the first term and r is the common ratio.
Substitute [tex]a=16,r=5,n=6[/tex] to get the 6th term.
[tex]a_6=16(5)^{6-1}[/tex]
[tex]a_6=16(5)^{5}[/tex]
[tex]a_6=16(3125)[/tex]
[tex]a_6=50000[/tex]
Therefore, the 6th term of the given sequence is 50000.

-Tobie the dog <3
Answer:
61%
Step-by-step explanation:
1) We are changing the percent from 56 down to 22
2) This means that there will be a negative change in percent
3) This is because the new value (22) is smaller than the old value (56)
4) We must find the change from 56 to 22 in a percent
1) Find the difference between 56 and 22 as a number.
The difference between 56 and 22 is 34
2) Divide the result from Step 1 by the starting number 56.
34 ÷ 56 = 0.60714285714
3) Multiply the result from Step 2 by 100 to get it in terms of percent.
0.60714285714 x 100 = 60.71
4) Round the result from step 3 to the nearest percent.
60.71 ≈ 61%
Make sure you round to the nearest whole percent. In this case it would be 61%

You start driving north for 4 miles, turn right, and drive east for another 4 miles. At the end of driving, what is your straight line distance from your starting point? Round to the nearest tenth of a mile.
The straight line distance between the start and finish point is required.
The straight line distance is 5.7 miles.
Pythagoras theorema = Distance traveled north = 4 miles
b = Distance traveled east = 4 miles
c = Straight line distance
The angle between the two paths is ninety degrees so, the Pythagoras theorem can be applied here.
Applying the Pythagoras theorem
[tex]c=\sqrt{a^2+b^2}\\\Rightarrow c=\sqrt{4^2+4^2}\\\Rightarrow c=4\sqrt{2}\\\Rightarrow c=5.7\ \text{miles}[/tex]
