walking the speed of 5km per hour, a boy hikes a distance of d km in t hours. Find the formula which describes d as a function of t.
Answer:
F(t) = 5t
Step-by-step explanation:
velocity = distance/time
distance = velocity × time
v - velocity
t - time
d - distance
v = 5
Distance as a function of time:
F(t) = 5×t
where F(t) represents distance
A boy hikes a distance of d km in t hours. The formula describes d as a function of t, F(t) = 5t.
What is the formula for velocity?velocity = distance/time
v - velocity
t - time
d - distance
v = 5
distance = velocity × time
Distance as a function of time
Therefore, F(t) = 5×t
Where F(t) represents the distance.

10(5-n)-1=29
Hey there!
10(5 - n) - 1 = 29
10(5) + 10(-n) - 1 = 29
50 - 10n - 1 = 29
49 - 10n = 29
-10n + 49 = 29
ADD 49 to BOTH SIDES
-10n + 49 - 49 = 29 - 49
WORK IT OUT or SIMPLIFY IT!
NEW EQUATION: -10n = -20

What are the measures of Angles a, b, and c? Show your work and explain your answers.
IM NOT LOOKING FOR ANY JOKES OR STUFF, JUST STRAIGHT UP SHOW THE WORK AND THE ANSWER PLEASE. (30 PNTS IF ANSWERED CORRECTLY) NEED HELP ASAP!
Answer:
a= 30
b= 60 (pretty sure)
c=105
Step-by-step explanation:
a is a vertical angle to 30, so that means it is also equal to 30.
To find b, since it's on a straight line, you can add up the angles in the triangle and solve for b.
30+90=120
120+b=180
b=60
To find c, you subtract 75 from 180 since it's also a straight line equal to 180 degrees.
On January 1, one share of stock in the LMNOP Corp was worth $85. By December, it lost 11.6% of its value. What is the new value of one share of LMNOP stock?
Answer:
multiple then dived the numbers together
Based on the previous worth of the stock and the value lost, the new value of the LMNOP stock is $75.14.
What is the new value of the LMNOP stock?The value of $85 lost approximately 11.6% of its value.
The new value can be found as:
= Previous stock price x ( 1 - percentage loss)
Solving gives:
= 85 x (1 - 11.6%
= 85 x 88.4%
= $75.14.

Sophia invests money in an account paying simple interest. She invests $70 and no money is added or removed from the investment. After one year, she has $72.80. What is the simple percent interest per year?
Answer:
72.80= 70(x)^1
x^1 is still x, so leave it at 72.8= 70x
divide 70 from both sides to leave x by itself
x= 1.04

g(n)=−50−15ng, left parenthesis, n, right parenthesis, equals, minus, 50, minus, 15, n Complete the recursive formula of g(n)g(n)g, left parenthesis, n, right parenthesis. g(1)=g(1)=g, left parenthesis, 1, right parenthesis, equals
Answer:
g(n) = g(n-1) -15
g(1) = -65
Step-by-step explanation:
We can find the recursive formula from the explicit formula for this arithmetic sequence by substituting 1 and (n+1) for n in the explicit formula.
__
g(n+1) = -50 -15(n+1) = (-50 -15n) -15 . . . . . find g(n+1)
g(n+1) = g(n) -15
and ...
g(1) = -50 -15(1) = -65
Then the recursive formula can ge written as ...
g(n) = g(n-1) -15
g(1) = -65
_____
Additional comment
We found g(n+1) = g(n) -15. Substituting n-1 for n in this formula puts it in the form we need for answering the question:
g((n-1)+1) = g(n-1) -15
g(n) = g(n -1) -15
Either of these forms tells you how to get the next term from the previous one.
Answer:
g(n) = g(n-1) -15
g(1) = -65

state the restrictions on the domain of the equation.
Answer: Choice E
[tex]x \ne -4, -1[/tex]
This is the same as saying [tex]x \ne -4 \text{ and } x \ne -1[/tex]
======================================================
Reason:
If we plugged x = -4 into the function, then the x+4 in the denominator turns to 0.
x+4 = -4+4 = 0
Dividing by zero is not allowed. It leads to a division by zero error. Therefore, we need to exclude -4 from the domain. Similar reasoning will exclude -1 as well because it makes the x+1 in the denominator to be zero.
Any other x value is valid.
Side note: The (x+1) terms cancel, which may appear that x = -1 is valid. However, your calculator will likely not perform such a simplification. It will simply try to directly compute the result using PEMDAS. That means x = -1 is likely to produce a division by zero error.
