Answer:
[tex]-\dfrac{5\sqrt{11}}{11}[/tex]
Step-by-step explanation:
Use the relationship between the various trig functions.
[tex]\tan{\theta}=\dfrac{\sin{\theta}}{\cos{\theta}}=\dfrac{\left(-\dfrac{5}{6}\right)}{\left(\dfrac{\sqrt{11}}{6}\right)}=-\dfrac{5}{\sqrt{11}}\\\\=-\dfrac{5}{\sqrt{11}}\cdot\dfrac{\sqrt{11}}{\sqrt{11}}=\boxed{-\dfrac{5\sqrt{11}}{11}}[/tex]

D. The population is multiplying itself by 10 each hour
Answers
Answer:
Option (C)
Step-by-step explanation:
From the graph attached in the picture,
Graph shows the relationship between time and the population of a culture of bacteria.
Option (A).
After 10 hours there are 10000 bacteria.
Since, at t = 0, number of bacteria = 10000.
False.
Option (B).
After 10 hours there are no more bacteria.
Since, from the given graph bacteria population is increasing exponentially every hour.
Therefore, from t = 0, where the population was 10000, bacteria will be much more in the numbers.
False.
Option (C).
The population began with 10000 bacteria.
True.
Option (D).
The population is multiplying itself by 10 each hour.
Since, growth is exponential therefore, bacteria population is growing faster.
False.
Option (C) is the answer.

Given the points below, find XY. Round to
the nearest hundredth.
X(-8, 2) and Y(7,-4)
Answers
Answer: 16.16
Step-by-step explanation:
xy in this situation, will be the distance between the two points.
(-8,2) (7,-4) Find the distance between the points
To ind the distance, find the difference in the x and y values,square them and add them to find the obtained number square root.
2-(-4) = 6
-8 - 7 = -15
6^2 + (-15)^2 = d^2 where d is the distance
36 + 225 = d^2
261 = d^2
d= [tex]\sqrt{261}[/tex]
d= 16.1554 rounded to the nearest hundredth is 16.16

a pile of sand has a weight of 90 kg the sand is put into a small bag a medium bag and a large bag in the ratio 2:3:7
work out the wight of sand in each bag
Answers
Answer:
15 kg, 22.5 kg, 52.5 kg
Step-by-step explanation:
Let the common multiplier of the given ratios be x. Therefore, weights of each bag would be 2x, 3x and 7x
According to the given information:
[tex]2x + 3x + 7x = 90 \\ 12x = 90 \\ x = \frac{90}{12} \\ x = 7.5 \: \\ \implies \\ 2x = 2 \times 7.5 = 15 \: kg \\ 3x = 3 \times 7.5 = 22.5 \: kg \\ 7x = 7 \times 7.5 = 52.5 \: kg[/tex]
Hence the weight of sand in bag would be 15 kg, 22.5 kg and 52.5 kg

solve for k. k/2 +1/2=3
Answers
Answer:
[tex]k = 5[/tex]
Step-by-step explanation:
Solve for [tex]k[/tex] :
[tex]\frac{k}{2} + \frac{1}{2} = 3[/tex]
-Multiply both sides of the equation by the denominator [tex]2[/tex] :
[tex]2 \times \frac{k}{2} + \frac{1}{2} = 3 \times 2[/tex]
[tex]k + 1 = 6[/tex]
-Subtract both sides by [tex]1[/tex]:
[tex]k + 1 - 1 = 6 - 1[/tex]
[tex]k = 5[/tex]
So, the value of [tex]k[/tex] is [tex]5[/tex].

The greater of two consecutive EVEN numbers is 40 less than twice the smaller number. Find the larger number
Answers
Answer:
44Step-by-step explanation:
z - some integer
2z - first given even integer (the smaller one)
2z+2 - even integer consecutive to 2z (the larger one)
2(2z) - twice the smaller number
2(2z) - 40 - the number 40 less than twice the smaller number
2(2z) - 40 = 2z + 2
4z - 40 = 2z + 2
2z = 42
2z+2 = 42+2 = 44
check:
2(2z)-40 = 2(42)-40 = 84-40 = 44
