Answer:
the student answer is incorrect
Correct answer: y = 109x + 5
Step-by-step explanation:
He STARTS with $5, which means it says aside. Since he REPEATEDLY recieves $109 EVERY day, it is as 109x because you don't know how much days there are. So the correct equation is y = 109x + 5.
Hope this helps!

The decay of 277 mg of an isotope is described by the function A(t)= 277e^0.019t , where t is time in years. Find the amount left after 64 years. Round your answer to the nearest mg. Show all of your work for full credit.
The decay of 277 mg of an isotope is described by the function
A(t)= 277e-0.019t,
where t is time in years.
To find the amount left after 64 years,
We substitute t = 64 in the expression.
A(t=64)= 277e-0.019(64)
or A(t=64) = 277 * e-1.216
= 277 * 0.29
= 82 mg
The height h, in feet of a model rocket t seconds after launch is given
by the equation h= 245t - 16t?. As the rocket descends, it deploys
a recovery parachute when it reaches 325 feet above the ground.
Express your final answer to the nearest tenth place.
What is the maximum height of the rocket?
Answer:
h_max = 324.09 ft
Step-by-step explanation:
The correct equation is;
h = 245t - 16t²
We are told that as the rocket descends, it deploys
a recovery parachute when it reaches 325 feet above the ground.
Thus;
245t - 16t² = 325
Thus;
16t² - 245t + 325 = 0
Using quadratic formula, we have the roots as;
t = 1.47s or 13.85s
We will pick the higher value.
Thus;
Maximum height will occur at t = 13.85 s
Thus, plugging in 13.85 for t into h = 245t - 16t², we have;
h_max = 245(13.85) - 16(13.85)²
h_max = 324.09 ft
review the graph. a ship is traveling according to the vector shown. what is the ships directional bearing?
Answer:
D on edge i got it right
Step-by-step explanation:
By reviewing the graph, when the ship is traveling so here the ship's direction should be 60 degrees west.
What is a vector?In terms of mathematics, the vector means the quantity where it does contain both magnitude and direction but does not involved the position. It involved the examples like velocity and acceleration.
According to the given graph, the movement of the ship is in south west direction along with angle 60 degrees
So, here option d is correct.

is the square root of 10 greater less than or equal to 5
Answer: it is less then 5
Step-by-step explanation:
Because 10 lies between two consecutive perfect squares (in increasing order) 10 is located between the square roots of these two numbers. This means that 10 is located between 10 is less than 5.
Answer:
less than
Step-by-step explanation:
finding the square root of 10 is a bit complicated because the number 10 is not a perfect square which has a number 0 at it's unit Place. Finding the square root of a number is the reverse process of squaring the number. we can find the square root of 10 using two methods one method is to find the root value using unit places and another method is with the help of long division method.
What is the average time in seconds between 2.15 2.05 2.02
Answer:
[tex]Average = 2.073[/tex]
Step-by-step explanation:
Given:
Time: 2.15, 2.05, 2.02
Required
Determine the average
Average is calculated as thus:
[tex]Average = \frac{\sum x}{n}[/tex]
In this case:
[tex]\sum x = 2.15+2.05+2.02[/tex]
and
[tex]n = 3[/tex]
[tex]Average = \frac{\sum x}{n}[/tex] becomes
[tex]Average = \frac{2.15+2.05+2.02}{3}[/tex]
[tex]Average = \frac{6.22}{3}[/tex]
[tex]Average = 2.073[/tex]

The graph shows the amount of money paid when purchasing bags of candy at the zoo:
A graph is shown. The x-axis is labeled from 0 to 9. The y-axis is labeled from 0 to 10. Four points are shown on the graph on ordered pairs 0, 0 and 1, 2 and 2, 4 and 3, 6. These points are joined by a line. The label on the x-axis is Bags of candy. The title on the y-axis is Total cost in dollars.
What is the cost of one bag of candy? (4 points)
a
$2
b
$4
c
$0
d
$6
Answer:
a $2
Step-by-step explanation:
One of the ordered pairs were (1, 2) which meant that at 1 bag of candy, the total cost in dollars is 2 based on the labelling of the x- and y-axis. Thus, the cost of one bag of candy is $2.
11. In a swimming race, Yvonne swam 0.18 mile.
David swam 4 times as far as Yvonne. How far
did David swim?
(A) 2.2 miles
B
0.22 mile
C.7.2 miles
D
0.72 mile
Answer: D= 0.72
Step-by-step explanation: Because 0.18 times 4 is 0.72 miles.
Answer:
D. 0.72 miles
Step-by-step explanation:
Since David swam 4 times as far is Yvonne, he swam 4 times more than 0.18. 0.18 times 4 is 0.72. If you want/need to do it in your head, just imagine 0.18 as 18, and that multiplied by 4 is 72. then move the decimal point back over before the 7, to get your answer.
Two of the other choices are clearly wrong because the actual answer is way less than the other choices (except for B). One way to quickly figure out which two (or sometimes three) are wrong is by rounding 0.18 up to 0.2. You can try this quickly because 0.2 is barely bigger than 0.18, and 0.2 is easy to multiply by 4. The answer you would get from multiplying 0.2 is not exactly correct, but gives you a general idea.

17. If p (m) = 4m3 + 3, the value of
p(1)-P(-1)
divides it int
Answer:
[tex]p(1) - p(-1) =8[/tex]
Step-by-step explanation:
Given
[tex]p(m) = 4m^3 + 3[/tex]
Required
[tex]p(1) - p(-1)[/tex]
First, we calculate p(1)
Substitute 1 for m in [tex]p(m) = 4m^3 + 3[/tex]
[tex]p(1) = 4(1)^3 + 3[/tex]
[tex]p(1) = 4*1 + 3[/tex]
[tex]p(1) = 4 + 3[/tex]
[tex]p(1) = 7[/tex]
Next, we calculate p(-1)
Substitute -1 for m in [tex]p(m) = 4m^3 + 3[/tex]
[tex]p(-1) = 4(-1)^3 + 3[/tex]
[tex]p(-1) = 4*-1 + 3[/tex]
[tex]p(-1) = -4 + 3[/tex]
[tex]p(-1) = -1[/tex]
[tex]p(1) - p(-1)[/tex] is then calculated as:
[tex]p(1) - p(-1) = 7 - (-1)[/tex]
[tex]p(1) - p(-1) = 7+1[/tex]
[tex]p(1) - p(-1) =8[/tex]
