A raft travels downriver at a rate of 6 miles per hour. The total distance d in mile that the raft travels is equal to the rate times the number of hours h. Dependent Variable: Independent variable: Equation:
Answer:
Dependent variable: total distance (d)
Independent variable: number of hours (h)
Equation: d = 6h
Step-by-step explanation:
In this case given, the dependent variable, total distance (d), is dependent on the independent variable, number of hours (h). This is because, a change in the value of h leads to the change in the value of d. In order words, total distance (d) is a function of the number of hours (h).
Therefore:
Dependent variable: total distance (d)
Independent variable: number of hours (h)
Rate: 6 miles/hr
Equation: d = 6h

The sum of the ages of mr a and mr z is 65 years. the difference of their ages is 7 years.what are their ages
Answer:
29, and 36
Step-by-step explanation:
65-7= 58
58/2= 29
29+7= 36
Answer:
29 and 36
Step-by-step explanation:
65 split in two since there are 2 people is 32.5
Since there is a 7 year difference, split 7 in half also which is 3.5
Subtract 3.5 from 32.5 to get the younger ones age and and add 3.5 to 32.5 to get the older one's age.
32.5-3.5= 29
32.5+3.5= 36

what is the surface area of this prism
Answer:
total surface area = 79.8 cm^2
Step-by-step explanation: open up the prism into nets, and it has a base of 3 and height of 2.6. do 1/2 times 3 times 2.6=3.9*2=7.8. Then do 3(3*8)=72. 72+7.8=79.8. I believe this is the answer to the best of my ability, hope this helps.

Brody has already read 8 books this year before joining a book club,and he plans to read 1 book every month now that he has joined. If Body has read 28 books so far,how many months has he been with his book club?
Answer: 20 months
explanation: You subtract 8 from 28 since 8 is the amount he had before he joined. He also said he planned on reading 1 book per month after joining the club. You want to subtract the 8 since it isn't relevant to the book club books read.

simplify the following using L'Hôpital's Rule:
[tex]\displaystyle\lim_{x\to 2}\frac{x^2+x-6}{x^2-4}[/tex]
[tex]\text{note:explanation is a must}[/tex]
Answer:
[tex] \displaystyle \: \frac{5}{4} [/tex]
Step-by-step explanation:
we are given a expression
we are said to solve it using L'Hôpital's Rule
recall, L'Hôpital's Rule:
[tex] \displaystyle \lim _{x \to \: c}( \frac{f(x)}{g(x)} ) = \lim _{x \to \: c} \frac{f ^{'}(x) }{ {g}^{'}(x) } [/tex]
it is to say the ' means derivative
our given expression:
[tex]\displaystyle\lim_{ x\to 2}\frac{x^2+x-6}{x^2-4}[/tex]
let's apply L'Hôpital's Rule
[tex]\displaystyle\lim_{ x\to 2}\frac{ \dfrac{d}{dx} (x^2+x-6)}{ \dfrac{d}{dx} (x^2-4)}[/tex]
some formulas of derivative
[tex] \displaystyle \: \frac{d}{dx} {x}^{n} = {nx}^{n - 1} [/tex]
[tex] \displaystyle \: \frac{d}{dx} {x}^{} = 1[/tex]
[tex] \displaystyle \: \frac{d}{dx} {c}^{} = 0[/tex]
[tex] \sf \displaystyle \: \frac{d}{dx} {f}^{} (x) + {g}^{}(x) = {f}^{'} (x) + {g}^{'}(x)[/tex]
use sum derivative formula to simplify:
[tex]\displaystyle\lim_{ x\to 2}\frac{ \dfrac{d}{dx} (x^2)+ \dfrac{d}{dx} (x) + \dfrac{d}{dx}( -6)}{ \dfrac{d}{dx} (x^2) + \dfrac{d}{dx} (-4)}[/tex]
simplify using exponents using exponent derivative formula:
[tex]\displaystyle\lim_{ x\to 2}\frac{ 2x+ \dfrac{d}{dx} (x) + \dfrac{d}{dx}( -6)}{ 2x + \dfrac{d}{dx} (-4)}[/tex]
use variable derivative formula to simplify variable:
[tex]\displaystyle\lim_{ x\to 2}\frac{ 2x+ 1+ \dfrac{d}{dx}( -6)}{ 2x + \dfrac{d}{dx} (-4)}[/tex]
use constant derivative formula to simplify derivative:
[tex]\displaystyle\lim_{ x\to 2}\frac{ 2x+ 1+ 0}{ 2x + 0}[/tex]
simplify addition:
[tex]\displaystyle\lim_{ x\to 2}\frac{ 2x+ 1}{ 2x }[/tex]
since we are approaching x to 2
we can substitute 2 for x
[tex]\displaystyle\lim_{ x\to 2}\frac{ 2.2+ 1}{ 2.2 }[/tex]
simplify multiplication:
[tex]\displaystyle\frac{ 4+ 1}{ 4}[/tex]
simplify addition:
[tex] \displaystyle \: \frac{5}{4} [/tex]
hence,
[tex]\displaystyle\lim_{ x\to 2}\frac{ \dfrac{d}{dx} (x^2+x-6)}{ \dfrac{d}{dx} (x^2-4)} = \frac{5}{4} [/tex]

Multiply: (4n + 4)(5n - 8)
Answer:
5n^2 - 3n - 8
Step-by-step explanation:
4n.5n - 4n.8 + 4.5n - 4.8
= 20n^2 - 32n + 20n - 32
= 20n^2 - 12n - 32
= 4 ( 5n^2 - 3n - 8 )
= 5n^2 - 3n - 8 [ answer ]
In square YOLA, RL=5x+28 and RO=8X-11
find the measure of RY.
If the answer is 12.8, move to R
If the answer is 93, move to S
If the answer is 13, move to T
If the answer is 25.5, move to u 9 of 15
Answer:
RL=5x+28 and
RO=8X-11
diagonal of square bisect equally the side
:.5x+28=8x-11
11+28=8x-5x
39=3x
x=39/3=13
RY=RL=5x+28=5×13+28=93If the answer is 93, move to answer.

Step-by-step explanation:
If x varies inversely as y and x=12 when y=9, find x when y=54
Answer:
x = 72
Step-by-step explanation:
We set the two equal to each other
x = 12/y = 9 is equal to x/y = 54.
In order for 9 to get to 54, you have to multiply it by 6. Since you multiplied the denominator with 6, you have to do the same with the numerator. 12 times 6 is 72.
x = 72
Is f(x+3) independent or dependent
Answer:
