If a car travels 200km in 2.5 hours, how far would it travel in 6 hours at the same rate of speed?
Answers
Answer: 480
Step-by-step explanation:
To solve this, you need to set up a proportion: 200/2.5 x/6
The 200 represents the km, and the 2.5 and 6 represent the hours. You can either solve this by multiplying 200 by 6 and setting it equal to 2.5 by x then solving for x, or you can find the rate the car travels in km in one hour. To do that, you divide 200 by 2.5 and get 80: this is your km per hour. Then you multiply that to 6 to see how far the car will go in 6 miles if it continues at the speed of 80 km per hour.
Answer:
Answer: 480 km
Step-by-step explanation:
As we know that if we keep speed or velocity constant, distance is directly proportional to time.
• In the first case:
[tex]{ \rm{d_{1} = kt _{1}}}[/tex]
d1 is 200 kmt1 is 2.5 hoursk is a constant of proportianality• Substitute the variables with their respective values to find the value of constant, k
[tex]{ \rm{200 = (k \times 2.5)}} \\ \\ { \rm{k = \frac{200}{2.5} }} \\ \\ { \underline{ \rm{ \: \: k = 80 \: km {h}^{ - 1} \: \: }}}[/tex]
• In the second case
[tex]{ \rm{d _{2} = kt _{2} }}[/tex]
d2 is what we needt2 is 6 hoursk is 80 kmh-¹[tex]{ \rm{d _{2} = (80 \times 6)}} \\ \\ { \boxed{ \boxed{ \rm{ \: \: d _{2} = 480 \: km \: \: }}}}[/tex]

• 2 Negatives = [Positive]
• 1 positive & 1 negative = [Negative]
• 2 positives = [Positive]
• 1 negative & 1 positive = [Negative]
° So, this means that your answer most likely will equal a NEGATIVE number because you have 1 NEGATIVE (-3) number and 1 POSITIVE (“c” or 4.2) number.
-3c
= -3(4.2)
= -12.6
Therefore, your answer is: -12.6

2. Write a quadratic function to the model to the graph to the right
Answers
We can use the quadratic function in vertex form, f(x) = a(x - h)^2 + k where:
(h, k) = vertex
a = determines whether the graph opens up or down, and makes the parent function wider or narrower.
* If a is positive, the graph opens up.
* If a is negative, the graph opens down.
h = determines how far left or right the parent function is translated.
k = determines how far up or down the parent function is translated.
Now that we defined each variable in the vertex form, we can plug in the values of the vertex (-4, 3) into the equation:
f(x) = a(x - h)^2 + k
f(x) = a(x + 4)^2 + 3
To solve for the value of “a”, we must choose another point from the graph. The y-intercept of the parabola happens to be (0, 19), so we’ll use its values to solve for “a”:
19 = a(0 + 4)^2 + 3
19 = a(4)^2 + 3
19 = a(16) + 3
Subtract 3 from both sides:
19 - 3 = a(16) + 3- 3
16 = 16a
Divide both sides by 16:
16/16 = 16a/16
1 = a
The value of a = 1. Since it is a positive number, then it confirms that the parabola opens upward.
Therefore, the quadratic function in vertex form is:
f(x) = (x + 4)^2 + 3

A DNA sequence can be represented as a string of the letters ACTG (short for adenine, cytosine, guanine, and thymine). How many DNA sequences are exactly 29 letters long?
Answers
To solve that question we can think by the following way:
The first letter can be any of the letters (A, C, T or G). Therefore there are 4 possibilites.To choose the second letter of the sequence, any letter also can be chose. So, one more time, there are 4 possibilites.Using the fundamental principle of counting, we will find out that can be formed [tex]4\times 4 = 16[/tex] differents sequences (for example, AA, AG, TT, TG, CT...).
Know we know that, we can generalize. If I have [tex]n[/tex] elements and I must choose one of them [tex]t[/tex] times to do a sequence, the total number of sequence that I can form will be [tex]n^t[/tex].
In our question, we want to know how many DNA sequence are exactly 29 letters long. As indicated above, the answer for that is [tex]4\times 4\times 4\times ... \times 4[/tex] (29 times) [tex]= 4^{29}[/tex].
Therefore, there are [tex]4^{29}[/tex] DNA sequences with exactly 29 letters long.

The body temperature in Fahrenheit of a sheep is modeled by the equation T=0.6sin(π28(t−9))+101.6, where t is the number of hours. To the nearest tenth of a degree, what is the temperature of the sheep when t=3? Do not include the units in your answer. NOTE: The angle is in degrees.
Answers
Answer:
101.6
Step-by-step explanation:
The temperature of the sheep when t = 3 is 101.24 degrees Fahrenheit.
Given that,
The body temperature in Fahrenheit of a sheep is modeled by the equation,
[tex]T = 0.6sin(\dfrac{\pi }{28} (3-9)) + 101.6[/tex]
where t is the number of hours.
Now, substitute t=3 into the equation;
[tex]T = 0.6sin(\dfrac{\pi }{28} (3-9)) + 101.6[/tex]
[tex]T = 0.6sin(\dfrac{\pi }{28} (- 6)) + 101.6[/tex]
Since, [tex]sin(\dfrac{\pi }{28} (- 6)) = - 0.5637[/tex]
Therefore, the temperature of the sheep when t=3 is:
[tex]T = 0.6sin(\dfrac{\pi }{28} (- 6)) + 101.6[/tex]
[tex]T = 0.6 \times - 0.5637 + 101.6[/tex]
[tex]T = 101.24[/tex]
So, the temperature of the sheep when t = 3 is 101.24 degrees Fahrenheit.
