Substituting u = 6x - 5, you write
y = cos(u)
Then differentiating with the chain rule gives
dy/dx = dy/du • du/dx
We have
dy/du = -sin(u)
du/dx = 6
so
dy/dx = -6 sin(u) = -6 sin(6x - 5)
Let f(x) = 3 x 2+1, find f(2)
15 points and BRAINLIEST Alyssa invested $500 into an account. The value of the account after t years can be found using the function r(t) = 500(1.068). What is the percent annual rate of change
in the value of the account?
Answer:
annual rate: r = 0.068
Step-by-step explanation:
The formula is r(t) = P(1+r)^t
Since the time is already in years we just have to solve for the rate
1 + r = 1.068
r = 0.068
The rate of change in the value of account is 0.068
What is rate of change?
'Rate of change is used to mathematically describe the percentage change in value over a defined period of time.'
According to the given problem,
Annual rate:
r = 0.068
The formula is r(t) = [tex]P( 1 + r )^{t}[/tex]
Therefore, solving for the rate
⇒ 1 + r = 1.068
⇒ r = 0.068

Solve for x:
(-3/2)x-9=-27
- 24
-12

12
i love these kind of questions :D
okay so lets write our problem down 1st:
(-3÷2)x-9=27
okay so you take one of your answers lets do A 1st and put is as x like this:
(-3÷2)-24x(-9)=27 now solve:
(think of PEMDAS)
P = perenthesis
E = exponents (which you dont have in this problem)
M = multiply
D = divide
A = add
S = subtract
do perenthesis 1st which would be (-3÷2)
(-1.5)-24x(-9)
now multiply 24x(-9)
(-1.5)-216 = (-214.5) does it equal -24 (which was what you plugged in for x)
no it doesnt so A cant be your answer. now do it for the rest of your answers :D

Answer: B
Step-by-step explanation:
There are several ways to solve this problem, but I think the easiest way is just to find the mean.
There are 12 total data points, and adding them all up you get 266.
mean = 266/12 = 22.167
The line in the middle of the box plot represents the mean, so the answer must be B.
Answer:
B

write tow additions that each have asum of -21.5.
Answer:
problem 1: -10.75+(-10.75)= -21.5
problem 2: (−5.375)+(−5.375)+(−5.375)
+(−5.375)= -21.5
Step-by-step explanation:
for the first one is just divided -21.5 by two and added the sum with itself.
for the second I divided -21.5 by 4 and added the sum up 4 times to get -21.5 again.
the equations might look a little too complicated but I hope this helped!

A line has the equation
y=x+3
Write down the coordinates of the point where the line intersects the v-axis.
Answer
(
Write down the coordinates of the point where the line intersects the x-axis.
Answer
Given:
The equation of line is
[tex]y=x+3[/tex]
To find:
The x-intercept and y-intercept.
Solution:
The equation of line is
[tex]y=x+3[/tex]
Putting x=0, we get
[tex]y=0+3[/tex]
[tex]y=3[/tex]
So, the y-intercept is (0,3).
Putting y=0 in the given equation, we get
[tex]0=x+3[/tex]
[tex]-3=x[/tex]
So, the y-intercept is (-3,0).
Therefore, the coordinates of the point where the line intersects the y-axis are (0,3). The coordinates of the point where the line intersects the x-axis are (-3,0).
An item had an original price of $5.00. It had a percent markup of 45%. What was the value of the markup?

markup = 45/100 x 5
markup = $2.25
selling price = $5 + $2.25

find the coordinates of point which divides the line segment joining the points (a+b,a-b) and (a-b,a+b) in the ratio 3:2 interally
Answer:
Coordinate of 0 = [tex]\bigg( \dfrac{5a-b}{5},\:\dfrac{5a+b}{5}\bigg)[/tex]Step-by-step explanation:
Let AOB be the line segmentPoint 'O' divides the line segment into m:n = 3:2Given:
Coordinate of a = (a+b, a-b)Coordinate of b = (a-b, a+b)Ratio = 3:2ToFind:
Coordinate of 0 (zero)Solution:
ATQ,
[tex]\dfrac{m}{n}=\dfrac{3}{2}[/tex]Coordinate of a = (x[tex]_{1}[/tex], y[tex]_{1}[/tex])Coordinate of b = (x[tex]_{2}[/tex], y[tex]_{2}[/tex])As we know that,
[tex]\implies\:\:x = \dfrac{mx_{2} + nx_{1}}{m + n}[/tex]
[tex]\implies\:\:x = \dfrac{(a-b)3 + (a+b)2}{3+2}[/tex]
[tex]\implies\:\:x = \dfrac{3a - 3b + 2a + 2b}{5}[/tex]
[tex]\implies\:\:\red{x = \dfrac{5a - b}{5}}[/tex]
Similarly,
[tex]\implies\:\:y = \dfrac{my_{2}+ny_{1}}{m+n}[/tex]
[tex]\implies\:\:y = \dfrac{(a+b)3+(a-b)2}{3+2}[/tex]
[tex]\implies\:\:y = \dfrac{3a+3b+2a-2b}{5}[/tex]
[tex]\implies\:\:\red{y = \dfrac{5a+b}{5}}[/tex]
Hence,
Coordinate of 0 is [tex]\blue{\bigg( \dfrac{5a-b}{5},\:\dfrac{5a+b}{5}\bigg)}[/tex]
