Answers
Answer:
c= 61m
Step-by-step explanation:
using Pythagoras theorem, sin33°=a/c
sin33°=33/c
using tables, sin33°=0.5446
substituting,
0.5446=33/c
cross multiply
0.5446*c=33
divide both sides by 0.5446
c=33/0.5446
c=60.5949321
c=61m (to the nearest whole number)

Determine if the function f(x)=x+4 is increasing or decreasing on the interval of 2≤x≤5. Justify your answer.
Answers
Step-by-step explanation:
Given
The function is [tex]f(x)=x+4[/tex]
for [tex]x_2>x_1[/tex], we will check the values of [tex]f(x_1)[/tex] and [tex]f(x_2)[/tex]
Take 3 and 4
[tex]f(4)=4+4\\f(4)=8[/tex]
Similarly,
[tex]f(3)=3+4\\f(3)=7[/tex]
Thus, [tex]f(4)>f(3)[/tex]
Also, [tex]f'(x)[/tex] is 1 i.e. a constant value. So, the function is increasing linearly for the given interval.

7 x 5e = 105
plz help
Answers
e=3.
So this is how I approached this. Since 7 is being multiplied, I divided both sides by 7 so 105/7 = 15. Then it becomes simple as 5e=15. We divide both sides by 5 and get e=3. Tip: just try isolating the variable and then life is much easier.
Answer:
e = 3
Step-by-step explanation:
7 × 5e = 105
35e = 105
35e ÷ 35 = 105 ÷ 35
e = 3
Which of the following is the explicit rule for a geometric sequence defined by
a recursive formula of…
A. an = 13.7041
OB. a, = 13.70-1
O C. a, = 7.13+1
O D. an = 7.130-1
Answers
Answer:
D
Step-by-step explanation:
Always apply the formula a_n=ar^(n-1) in this type of questions, since you know that the first term, a is 7 and the common ratio, r is 13. Therefore you can substitute a = 7 and r = 13 into the equation which equals to a_n=7×13^(n-1)
The explicit rule for a geometric sequence defined by,
a(n) = 7 × 13ⁿ⁻¹
We have to given that,
a (n) = 13 a (n - 1)
Now, We can simplify as,
a (n) / a (n - 1) = 13
a (n) = 13 a (n - 1)
Since, We know that,
a(n) = a × rⁿ⁻¹
Here, a = 7
a(n) = 7 × 13ⁿ⁻¹
Hence, Option c is true.

The difference of the square of a number and 18 is equal to 3 times that number. Find the positive solution.
Answers
Answer:
18 = 3 x 6
Step-by-step explanation:
If you don't know the difference of the square of a number you can already see that it's telling 18 = 3 times that number so identify the missing number by multiplying 3 times a number.
18 = 3 x ?
18 = 3 x 6
18 = 18
:D
Answer:
6
Step-by-step explanation:
Let us start by writing an equation using the variable x.
The square of a number x minus 18 equals 3 times x:
[tex]x^{2} -18=3x[/tex]
Great! Now let us solve for x by moving the 3x term to the left side of the equation and obtain a quadratic equation:
[tex]x^{2} -3x-18=0[/tex]
We can use the quadratic formula [tex]\frac{-b±\sqrt{b^{2}-4ac } }{2a}[/tex] to solve for x. *Please ignore the A after b. I cannot remove it for some reason.*
From our equation, a represents the coefficient of the term with degree of 2. Therefore, our a variable is 1. b represents the coefficient of the term with degree 1. Out variable b is therefore -3. Lastly, c represents the term with degree 0. Our c variable is -18. Lets solve!
[tex]\frac{3 ±\sqrt{(-3)^{2}-4*1*(-18) } }{2*1} =\\\frac{3 ±\sqrt{9+72} }{2} =\\\frac{3 ±\sqrt{81} }{2} =\\\frac{3 ±9}{2} \\\\[/tex]
Now we have two possible solutions. Let us start with the addition version:
[tex]\frac{3+9}{2} =\\\frac{12}{2} =\\6[/tex]
Alternatively you could try the subtraction version:
[tex]\frac{3-9}{2} =\\\frac{-6}{2} =\\-12[/tex]
However, the question asks to find the positive solution. Therefore, out answer is 6.
I hope this helps! Please let me know if you have any questions :)

1. Pick two animals to be in a race and answer the following questions.
a. Suppose two animals are in a race. Choose two animals from Table 1 and calculate the speed of each animal in yards per second. (6 points)
Example: Kangaroo – 30 miles/hour multiply by 1760 (conversion to yards) divided by 3600 (conversion to seconds). So the speed of a Kangaroo is 14.67 yd/sec.
b. You decide how much of a head start (in yards) the faster animal will offer the slower animal. For each animal, write an equation relating speed (v), distance from the starting line (d), and time (t). (6 points)
Formula:
c. Graph the two equations on the same coordinate plane. (4 points)
d. How long will it take the faster animal to overtake the slower animal? How many yards from the starting line are the animals when the faster animal overtakes the slower animal? (3 points)
e. Reduce the head start by half and repeat parts (c) and (d) from above. (9 points)
(c)
(d) How long will it take the faster animal to overtake the slower animal? How many yards from the starting line are the animals when the faster animal overtakes the slower animal?
2. Pick a third animal and answer the following questions.
a. Choose a third animal. Calculate its speed in yards per second. Compare its speed with the speed of the two animals you chose in Activity 1. (6 points)
b. Decide which two animals should get head starts and how much of a head start each should get. Write three equations relating distance from the starting line to time. (10 points)
c. Graph all three equations on the same coordinate plane. (6 points)
Part B: Which Community Garden Plan? (50 possible points)

2. The plans for the square garden shows a length of 12 m. What is the width of the square garden? Using the area from problem 1, what is the value of x? What is the total area of this square garden? (9 points)
3. Juan’s plans include a rectangular garden with an area of (x2 + 14x + 24) m2. Write expressions for the length and width of the rectangular garden. (8 points)
4. The plans for the rectangular garden shows a length that is 6 m. longer than the length of the square garden. What is the width of the rectangular garden? How much shorter is the width of the rectangular garden than the square garden? (9 points)
5. Write expressions for the perimeter of each garden in terms of x. Then find each perimeter for the x-values calculated in the previous questions. (8 points)
