Step-by-step explanation:
A lost turtle - swimming 13 feet below the surface of the water - begins to ascend at 0.5 foot per second. In hopes of (harmlessly) capturing the turtle, a diver jumps into the water to a depth of 4 feet before descending at a rate of 0.25 foot per second.
a) Write an equation to model the position of the turtle at any given time.
b) Write an equation to model the position of the diver at any given time.
c) After how long will the diver be able to catch the turtle?
d) At what depth will the diver be able to catch the turtle?

Answer:
a) T(t) = -13 +0.5t
b) D(t) = -4 -0.25t
c) 12 seconds
d) 7 feet
Step-by-step explanation:
a) The turtle starts at -13 feet and increases its elevation relative to the water's surface by 0.5 ft/second. After t seconds, the turtle will be 0.5t feet closer to the surface, so its depth will be ...
T(t) = -13 +0.5t
__
b) The diver starts at -4 feet and decreases their elevation relative to the water's surface by 0.35 ft/second. After t seconds, the diver will be 0.25t lower than the initial position, so their depth will be ...
D(t) = -4 -0.25t
__
c) The diver and turtle will be at the same depth when ...
T(t) = D(t)
-13 +0.50t = -4 -0.25t
0.75t = 9 . . . . . . . . . . . . add 13+0.25t
t = 12 . . . . . . . . . . . . . . . divide by 0.75
The diver and turtle will be at the same depth after 12 seconds.
__
d) That depth will be ...
T(12) = -13 +0.5(12) = -13 +6 = -7
The diver and turtle meet at a depth of 7 feet.
A triangle has one side that measures x, and the other two sides each measure 4 inches less than x. The perimeter is 19 inches.
What is the measure of x?
5
3
9
2
Answer:
x=9
Step-by-step explanation:
x + x - 4 + x - 4 = 19
3x - 8 = 19
3x = 19 + 8
3x = 27
x = 9
Answer: x=9
Step-by-step explanation:
There are three sides 2 that are x-4 and 1 that is x. The equation would be
x+2(x-4)= 19 so you would simplify to get
X+2x-8=19 then 3x=27 then divide by three to get x=9

Rewrite the expression in the form 5^n
(5^-8) (5^-10)
Step-by-step explanation:
This problem is all about bases and exponents. Because we have a quotient and the bases are both 5's, that means that we can use the rule of exponents for quotients to rewrite and simplify:
That's the simplification as long as you are "allowed" to leave the exponent as a negative number.

I hoped this help and little I didn't understand everything you meant.
I really need help on this question! Thank you!
Answer:
A
Step-by-step explanation:
We know the following:
[tex]OE=5\\\\FG=4\\\\EF=8\\\\[/tex]
so the segment EF is equal to
[tex]EF=EG+GO+OF\\\\[/tex]
and here we can do a trick :)
[tex]EF=(EG+GO)+GO+(OF+OG)-2GO\\\\[/tex]
you see it's the same
[tex]EF=EO-GO+FG\\\\[/tex]
now we plug the values given
[tex]8=5-GO+4\\\\8=9-GO\\\\GO=9-8\\\\GO=1[/tex]
so it's option A

The rate to rent a truck for a day is a one-time fee of $35 and $0.20 per mile.
Write an expression to model this situation.
How far could you travel if you drove 40 miles?
Answer: y= $0.20x + $35 or y= $0.20 * 40 + $35 (Depending on what you mean)
Step-by-step explanation:
The equation for these types of problems is y = mx + b.
M would be $0.20, because that is the value that can repeat, based on x. For example, if this was 2 dollars per mile (m) for 3 miles, (x) than y, the total amount for mx would amount to 6 dollars.
Now, 35$ Is a one time fee (b), so you can add that separately to $0.20x.
If you plug everything in, you would get y= $0.20x + $35.
I am not very sure about what you mean by “ How far you could you travel if you drove 40 miles”, but if you mean how much would you pay to drive 40 miles, I can help there.
Now that we know x would be the amount of miles, we can plug that into the equation.
You would get y= $0.20 * 40 + $35.
Sorry, I’m not that good at explaining, but I hoped this helped!
