Stacey is going rock climbing.She stats 2.5 kilometers up a cliff , climbes up 7 more kilometerd and then climbs all the way down to the bottom of the cliff. What is the total distance of her climb ?
Answer:
19 kilometers
Step-by-step explanation:
2.5 kilometers + 7kilometers
= 9.5 kilometers
+ the additional 9.5 for the trip down
=19 kilometers in total
Stacey total distance for climbing was 16.5 km
Stacey started 2.5 km up the cliff so this 2.5km is not counted as she started at that point.
She then climbed 7 km up the cliff.
After that she climbs back down to the bottom of the cliff. This time she climbs both the 7km she climbed previously, and the 2.5km she hadn't climbed before.
Tracy total climbing distance is:
= Distance climbed up + Distance climbed down
= 7 + ( 7 + 2.5)
= 7 + 9.5
= 16.5 km
In conclusion, Stacey climbed 16.5 km in total.

terms of log .
log 6x^4
Answer:
P=log(2)+log(3)+4.log(x)
Step-by-step explanation:
To solve the problem, we need to recall the following properties of the logarithms:
[tex]log(x.y)=log(x)+log(y)[/tex]
[tex]log(x^y)=y.log(x)[/tex]
We have the expression:
[tex]P=log(6x^4)[/tex]
Factor 6=2*3:
[tex]P=log(2\cdot 3x^4)[/tex]
Apply the property of the product:
[tex]P=log(2)+log(3)+log(x^4)[/tex]
Now apply the property of the exponent:
P=log(2)+log(3)+4.log(x)
Find f'(x) if f(x)=3x- 12
Answer:
4
Step-by-step explanation:
f(x) = 12 and f(x) = 3x
12/3 = 4 and the function for f(x) is 3(4)
The derivative of the function f(x) = 3x - 12 is 3.
What is a derivative ?Derivative of a function measures the rate of change of a function it can also be defined as the slope of the function.If given dy/dx it states the rate of change of y with respect to x.
According to the given question we have find the first derivative of the function f(x) = 3x - 12.
Given f(x) = 3x - 12
f'(x) = 1(3)x¹⁻¹ + 0 ( derivative of any constant is 0 )
f'(x) = 3x⁰.
f'(x) = 3.

what is an equation that passes through -1,2 and is parallel to the point 3x+y=3 ?
Answer:
y=3x+5
Step-by-step explanation:
For this you can use the point-slope formula: y-y1=m(x-x1). Since the line we're looking for is parallel, both slopes are equivalent.
First, you have to rewrite the primary equation into standard form, which would rewrite to y=3-3x or y=-3x+3. Then, you can use the information we have in the point-slope formula:
y-(2)=3(x+1)
y-2=3x+3
y=3x+5
Check:
(2)=3(-1)+5
2=-3+5

You are a contractor and charge $65 for a site visit plus an additional $15 per hour for each hour you spend working at the site. Write and solve an equation to determine how many total hours you have to work to earn $950 working at two separate work sites
Answer:
h = 59 hours
Step-by-step explanation:
Total earnings = fixed charge + variable charge
Fixed charge = $65
Variable charge = $15h
Where, h = number of hours
Total earnings = $950
Total earnings = fixed charge + variable charge
950 = 65 + 15h
Subtract 65 from both sides
950 - 65 = 65 + 15h - 65
885 = 15h
Divide both sides by 15
h = 885 / 15
= 59
h = 59 hours

Your phone plan charges you an initial fee, and then a certain amount depending on the amount of data you use. They send you periodic updates of your usage and your current bill cost. After using 3 GB of data, you owe $30. After 5 GB of data, you owe $40. What is the cost per GB of data?
Answer:
$5
Step-by-step explanation:
Let
x = initial fee
y = fees depending on the amount of data he use
After using 3 GB of data , he owes $30.
After using 5 GB of data , he owes $40.
The equations are
x + 3y = 30 (1)
x + 5y = 40 (2)
Subtract (1) from (2) to eliminate x
5y - 3y = 40 - 30
2y = 10
Divide both sides by 2
y = 10/2
y = $5
Substitute y = 5 into (1)
x + 3y = 30
x + 3(5) = 30
x + 15 = 30
x = 30 - 15
x = $15
Cost per GB of data = $5

I got it right on Edge, hope this helps
The expression represents the second consecutive odd integer is X + 2
and for the third consecutive odd integer is X + 4.
What are integers?All whole numbers and negative numbers are considered integers. This means that if we combine negative numbers with whole numbers, a set of integers is formed.
An integer, which can comprise both positive and negative integers, including zero, is a number without a decimal or fractional portion.
Given One example of consecutive odd integers would be 3, 5, 7, 9, ...
the difference between 2 consecutive numbers is
5 - 3 = 2
when X is the first odd integer,
the second consecutive odd integer is X + 2
difference between 3rd and first digit is
7 - 3 = 4
the third consecutive odd integer is X + 4
Hence adding the consecutive even numbers to the first digit of odd numbers gives the consecutive odd numbers.

Camila is driving on a long road trip. She currently has 10 gallons of gas in her car. Each hour that she drives, her car uses up 1.75 gallons of gas. How much gas would be in the tank after driving for 3 hours? How much gas would be left after tt hours?
Answer:
gas left after 3 hours = 4.75
gas left after t hours = 10-1.75t
Step-by-step explanation:
According to DeltaMath "Since Camila uses 1.75 gallons of gas per hour, she would use 1.75 x 5, or 5.25 gallons in 3 hours. Since Camila started with 10 gallons in the tank, the amount of remaining after 3 hours would be 10-5.25 or 4.75 gallons. "

Answer:
40 degrees
Step-by-step explanation:
There are parallel lines and a transversal. That means that angle a and b are congruent due to corresponding angles theorem.
5x-5=3x+13
Move the variables on one side and numbers on the other. 2x=18
Finally, x=9 And then after you plug it in, your final answer for angle b is 40 degrees.
Answer:
Step-by-step explanation:
Well both angles are the same because the lines are parallel and then there is a line going through them so <A = <B meaning
5x-5=3x+13 and then you solve
5x - 3x = 13 + 5
2x = 18
x = 9
