Tyler is going on a hiking trip. At the end of the
first day he has 7,250 feet left to climb. He plans
to climb 400 feet each day.
Write an explicit formula to model the situation.
At the end of which day does Tyler have 1750
feet left to climb?
Answer:
(1) F(n) = 8050 -400n
(2) 16 days
Step-by-step explanation:
Tylor first day he has left 7,250feet left to climb, this means that he has already climbed his 400ft on his first day
This will produce an arithmetic series for the distances left to climb as each day passes
initial climb = 7,250+400 = 7,650
Arithmetic Series
7650 , 7250 , 6850 , 6450 ......
a = 7650 , d = -400
(1) Explicit formula
F(n) = a + (n-1)d
= 7650 + (n-1)(-400)
= 7650 +400 -400n
F(n) = 8050 -400n
(2) 8050 -400n = 1750
6300 = 400n
n = 6300 /400 = 15.75 = 16 days( approximately)
So after 16days (approximately) Taylor will have 1750ft left to climb.

Show that the ratios 10 20 and 30 60 form a proportion by finding a common multiplier. Show that the ratios in part (a) are equal by writing them in simplest form. Show that the ratios 10 20 and 30 60 form a proportion by finding a common multiplier. Show that the ratios in part (a) are equal by writing them in simplest form.
Answer:
Common multiplier = 10, Equal simplest forms = 1/2
Step-by-step explanation:
Ratio 10 / 20 & 30 / 60 have common multiplier 10.
As 10, 20, 30, 60 are all multiples of 10.
These ratios are equal, as 10/20 = 30/60 = 1/2 (their simplest form)
Solve for F.
C=5/9 F-32
Answer:
f=9c+288/5
Solving:
solving for f.
c=5/9f−32
Step 1: Flip the equation.
5/9f−32=c
Step 2: Add 32 to both sides.
5/9f−32+32=c+32
5/9f=c+32
Step 3: Divide both sides by 5/9.
5/9f/5/9=c+32/5/9
f=9c+288/5
Solving:
Solving for c.
c=5/9f−32
Suppose that when a skunk sprays, the odor has a half-life stink potency of
8 hours. This means that the skunks spray would have a stink odor of 100%
when it is first sprayed. Then, after 8 hours, it would smell half as bad (and
be at 50% of its potency). What percent potency would still exist after 1
day? Explain/show your work.
Answer:
12.5% Potency
Step-by-step explanation:
8 x 3 = 24 hours in 1 day so 3 half lifes would progress in 24 hours.
100% Hour 0 Spray (Half Life 0)
50% Hour 8 Spray (Half Life 1)
25% Hour 16 Spray (Half Life 2)
12.5% Hour 24 Spray (Half Life 3)
Answer:
12.5%

Simplify:
4f – 15s + 16f – 20 + 17 – 12f
Answer:
8f-15s-3
Step-by-step explanation:
Combine the like terms. 4f plus 16f is 20f. 20f minus 12f is 8f. There are no like terms for 15s so it stays. Finally, combine -20 and 17 and you get -3. So the answer is 8f - 15s - 3.
Answer:
8f−15s−3

Given SD HT; SH=ST prove SHD= STD
Answer:
Δ SHD ≅ Δ STD (By SAS)
Step-by-step explanation:
Given:
SD⊥HT
SH=ST
Prove:
Δ SHD ≅ Δ STD
Computation:
SH=ST (Given)
SD = SD (Common)
∠SHD = ∠SDT (right angle) (SD⊥HT)
So,
Δ SHD ≅ Δ STD (By SAS)
The proof of [tex]\Delta SHD\cong \Delta STD[/tex] is given below.
Given, SD is perpendicular to HT.
We have to prove [tex]\Delta SHD\cong \Delta STD[/tex].
Now, In [tex]\Delta SHD\ and\ \Delta STD[/tex],
[tex]\angle SDH=\angle SDT[/tex] ( since SD perpendicular to HT, so both will be 90 ).
[tex]SH=ST[/tex] ( given in question ).
[tex]SD= SD[/tex] ( common side in both the triangle ).
So, by Right angle hypotenuse congruence rule,
[tex]\Delta SHD\cong \Delta STD[/tex].
Hence the [tex]\Delta SHD\cong \Delta STD[/tex] proved above.

(365 days per yr Jonas practices guitar 1 hour a day for 2 years. Bradley practices the guitar 2 hours a day more than Jonas. How many more minutes does Bradley practice the guitar than Jonas over the course of 2 years? No leap years
Answer:
87,600 minutes
Step-by-step explanation:
Given that practice time by Jonas :
1 hour per day for 2 years :
Bradley practices : 2 hours a day more than Jonas,
How many more minutes does Bradley practice the guitar than Jonas over the course of 2 years
Number of days in a year = 365 days
2 hours per day for (2 * 365) days :
2 * (2 * 365) = 1460 hours
Recall :
60 minutes = 1 hour
(60 * 1460) = 87,600 minutes
