Step-by-step explanation:
Use power rule and chain rule.
y = cos²(5x³ − 2x)
dy/dx = 2 cos(5x³ − 2x) (-sin(5x³ − 2x)) (15x² − 2)
dy/dx = 2 cos(5x³ − 2x) sin(5x³ − 2x) (2 − 15x²)
Use double angle formula to simplify:
dy/dx = sin(10x³ − 4x) (2 − 15x²)
Determine whether the relation {(9, 3), (6,2), (3, 2), (3, 1), (6,-2)} is a function. Explain why/Why

solve for k. k/2 +1/2=3
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].

let f(x)=5x-2 and g (x)=6x+3 find g(f(3))
Answer:
81
Step-by-step explanation:
f(x)=5x-2
g (x)=6x+3
g(f(3))
First find f(3)
f(3) = 5*3 -2
= 15-2
= 13
Then find g(13)
g(13) = 6*13 +3
=78 +3
= 81
Answer:
81
Step-by-step explanation:
Solve 3 as x
5(3)-2

The greater of two consecutive EVEN numbers is 40 less than twice the smaller number. Find the larger number
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

Given the points below, find XY. Round to
the nearest hundredth.
X(-8, 2) and Y(7,-4)
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 After 10 hours there are 10.000 bacteria.
B. After 10 hours there are no more bacteria
C The population began with 10,000 bacteria
D. The population is multiplying itself by 10 each hour
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.

What is the reasoning?
Answer:
yes, i agree. the right angle is 90 and 90+90=180. The law of the congruent angle states that if one angle in a the plane is right then the other connected must be as well, making line L 180.

i badly explained it however you should get the answer correct with that. i think... use your brain in addition to mine.
is this a function graph?
Answer:
No, this is a relation
Step-by-step explanation:
You can do a vertical line test to see if a function is actually a function or not. Simply draw vertical lines over the graph
If the x-value has 2 or more y values then it is NOT A FUNCTION
Answer:
No! This is not a function.
Step-by-step explanation:
If you write a vertical line through the graph, it will cross through it twice. That means it's NOT a function graph.
