Answer:
y' = -sin(x)
Step-by-step explanation:
Your table of derivatives of trig functions tells you the derivative of the cosine is the opposite of the sine.
dy/dx = -sin(x)
Answer:
[tex]→y = \cos(x) \\ \boxed{\frac{dy}{dx} = - \sin(x) }✓[/tex]
dy/dx=-sin(x) is the right answer.Nootmath How can you tell a graph of an exponential represents decay?

Answer:
0.5
Step-by-step explanation:
To find the rate of change, we can use the slope formula of [tex](y^2-y^1) / (x^2-x^1)[/tex].
Plugging in the first two points gets us:
[tex](1 - .5) / (1-0)[/tex]
[tex]0.5 / 1[/tex]
[tex]0.5[/tex]
That is your rate of change.
A cylinder has a height of 9 inches. Its volume is 4,775.94 cubic inches l. What is the radius of the cylinder
Answer:
The radius of the cylinder is 13.0 inches.
Step-by-step explanation:
The volume of a cylinder is given by:
[tex] V = \pi r^{2}h [/tex]
Where:
V: is the volume = 4775.94 in³
r: is the radius =?
h: is the height = 9 in
Hence, by solving the above equation for "r" we have:
[tex] r = \sqrt{\frac{V}{\pi h}} = \sqrt{\frac{4775.94 in^{3}}{\pi 9 in}} = 13.0 in [/tex]
Therefore, the radius of the cylinder is 13.0 inches.
I hope it helps you!

Answer:
B
Step-by-step explanation:
find the area. the figure is not drawn to scale.
Answer:
131.5
Step-by-step explanation:
To find the area of the rectangle, we multiply the base and the height.
In this case, the base is 8 and the height is 13 I think. ( Your picture cuts it off very poorly)
8 x 13 = 104
Now, we need to find the area of the triangle. It is the same equation as the rectangle but we divide the result by 2.
11 * 5 = 55
55/2 = 27.5
27.5 + 104 = 131.5
If it's wrong, it's probably because of the picture. I can't tell what the height is of the rectangle, because it's certainly not 3.

Answer:
80
Step-by-step explanation:
18^2 + 80^2 = 82
324 + 160 = c^2
Answer:
80 cm
Step-by-step explanation:
To solve this problem, you can use the pythagorean theorem which is a^2 + b^2 = c^2. We are given that a = 18, and c as the hypotenuse equals to 82. We can plug these numbers into the theorem:
18^2 + b^2 = 82^2
324 + b^2 = 6724
b^2 = 6400
b = 80 cm
Solve Equations: 8x + 260 = -5x + 650
Answer:
8x+260=-5x+650
8x+5x=650-260

What is Limit of g (x) as x approaches 1, if it exists?
0
7,000,000
700,000,000
DNE
Answer:
7,000,000
Step-by-step explanation:
Limit of a function:
The limit of a function is finding looking at it's lateral limits.
If the lateral limits are equal:
The limit exists.
[tex]\lim_{x \rightarrow a} f(x) = \lim_{x \rightarrow a^{+}} f(x) = \lim_{x \rightarrow a^{-}} f(x)[/tex]
If lateral limits are different:
That is:
[tex]\lim_{x \rightarrow a^{+}} f(x) \neq \lim_{x \rightarrow a^{-}} f(x)[/tex], then the limit does not exist.
In this question:
To the left of 1, that is, 0.9999....
[tex]\lim_{x \rightarrow 1^{-}} g(x) = 7,000,000[/tex]
To the right of 1, that is, 1.0001...
[tex]\lim_{x \rightarrow 1^{+}} g(x) = 7,000,000[/tex]
Since the both limits are the same, the limits exists and it's value is of 7,000,000.

The height above the ground of a passenger on a Ferris wheel t minutes after the ride begins is modeled by the differentiable function H, where H(t) is measured in meters. Which of the following is an interpretation of the statement H'(7.5) = 15.708?
(A) The Ferris wheel is turning at a rate of 15,708 meters per minute when the passenger is 7.5 meters above the ground.
(B) The Ferris wheel is turning at a rate of 15.708 meters per minute 7.5 minutes after the ride begins.
(C) The passenger's height above the ground is increasing by 15.708 meters per minute when the passenger is 7.5 meters above the ground.
(D) The passenger's height aloe the ground is increasing by 15.708 meters per minute 7.5 minutes after the ride begins.
(E) The passenger is 15.708 meters above the ground 7.5 minutes after the ride begins.
Answer:
(D) The passenger's height aloe the ground is increasing by 15.708 meters per minute 7.5 minutes after the ride begins.
Step-by-step explanation:
Here, H(t) is the height after the t minutes of time.
Given :
H'(7.5) = 15.708 meters / minute
H'(t) = [tex]$\frac{d(H(t))}{dt}$[/tex]
= rate of change of the height
So, here, H'(t) = rate of change of height
Therefore, H'(7.5) = 15.708 meters / minute
It shows that the passenger's height is increasing at rate 15.708 meters per minute at time t = 7.5 minutes after the ride begins.
Write two fractions that are equal to 1/2.
Answer:
2/4 nd 4/8
Step-by-step explanation:
Extras; 3/6, 5,10, 6/12
Answer:
2/4 and 3/6 .
Step-by-step explanation:
Given :-
A number 1/2.We need to write two fractions which equals to 1/2 . For that we can multiply the denominator and numerator by same number .
First equal fracⁿ :-
[tex]:\implies[/tex] 1/2 × 2/2 = 2/4
Second equal fracⁿ :-
[tex]:\implies[/tex] 1/2 × 3/3 = 3/6
Hence the two equal fractions are 2/4 and 3/6 .What coordinates will remain the same? What coordinates will change to the opposite between the pre-- and post-image?
Answer:
Y values will stay the same
Step-by-step explanation:
Reflecting over the Y axis will alter the distance left and right but not up and down. so only Y remains unchanged
Math grade 9, can anyone solve it
Answer:
a) Acceleration = 2.4 m per seconds²
b) Distance traveled = 132 m
Step-by-step explanation:
a). Acceleration of an object is defined by the equation,
v = u + at
Here, v = Final speed
u = Initial speed
a = Acceleration
t = Duration Or time
From the graph attached,
Between t = 0 and t = 5 seconds,
v = 12 meter per second
u = 0
t = 5 seconds
B substituting values in the equation,
12 = 0 + a(5)
a = [tex]\frac{12}{5}[/tex]
a = 2.4 m per seconds²
b). Equation representing distance traveled by an object,
v² = u² + 2as
Here, v = Final speed
u = Initial speed
a = Acceleration
s = Distance traveled
By substituting these values in the given equation,
1). Between t = 0 to t = 5 seconds,
(12)² = 0 + 2(2.4)s
s = [tex]\frac{144}{4.8}[/tex]
s = 30 m
2). Between t = 5 to t = 12 sec
Car moved with a constant speed (Acceleration = 0)
Distance traveled = Speed × Time
= 12 × 7
= 84 m
3). Acceleration of the car between t = 12 sec to t = 15 sec
By substituting the values in the equation,
v = u - at
0 = 12 - a(3)
a = 4 meter per seconds²
Distance traveled in this duration,
v² = u² - 2as
0 = (12)² - 2(4)s
144 = 8s
s = [tex]\frac{144}{8}[/tex]
s = 18 m
Therefore, total distance covered by the car = 30 + 84 + 18
= 132 meters

I need help for my hw asap!! Help pls!!! Thank you
Answer:
1. S.A. = 4350 cm²
2. S.A. = 864 cm²
3. S.A. = 240 cm²
4. S.A. = 224 m²
5. S.A. = 301.6 in.²
6. S.A. = 6,082.1 cm²
7. S.A. = 923.6 in.²
Step-by-step explanation:
1. Surface area of the rectangular prism = 2(LW + LH + WH)
L = 45 cm
W = 25 cm
H = 15 cm
S.A. = 2(45*25 + 45*15 + 25*15)
S.A. = 4350 m²
2. Surface area of the cube = 6a²
a = 12 cm
S.A. = 6(12²)
S.A. = 864 cm²
3. Surface area of triangular prism = bh + (s1 + s2 + s3)*H
b = 4 cm
h = 6 cm
s1 = 4 cm
s2 = 7 cm
s3 = 7 cm
H = 12 cm
Plug in the values
S.A. = 4*6 + (4 + 7 + 7)*12
S.A. = 24 + (18)*12
S.A. = 24 + 216
S.A. = 240 cm²
4. Surface area of the square based pyramid = area of the square base + 4(area of 1 triangular face)
S.A. = (8*8) + 4[(8*10)/2]
S.A. = 64 + 4(40)
S.A. = 64 + 160
S.A. = 224 cm²
5. Surface area of the cone = πrl + πr²
r = 6 in.
l = 10 in.
S.A. = π*6*10 + π*r²
S.A. = 60π + 36π
S.A. = 301.592895
S.A. = 301.6 in.² (nearest tenth)
6. Surface area of the sphere = 4πr²
r = 22 cm
S.A. = 4*π*22²
S.A. = 1,936π
S.A. = 6,082.1 cm² (nearest tenth)
7. Surface area of the cylinder = 2πrh + 2πr²
r = 7 in.
h = 14 in.
S.A. = 2*π*7*14 + 2*π*7²
S.A. = 923.6 in.² (nearest tenth)

Ajay has equal numbers of rock songs and pop songs loaded on his personal music player. He has it set to play songs plz helpp...on a random shuffle. Suppose Ajay is designing a simulation that could be used to estimate the probability that the next three songs to play are all alternative rock songs.
Which simulation design could Ajay use to estimate the probability?
O A. Random digits Let 1, 2, 3, 4,5rock Let 6,7,8,9,0 pop Select three rondom digits. Repeat
O B. Number cube Let 1,2 = rock Let 4,5 - pop Roll cube three times. Repeat
O C. Number cube Let 1 = rock Let 2 = pop Roll cube three times. Repeat
O D. Random digits Let 1,2 = rock Let 3,4,5,6,7,8,9,0 = pop select three digits. repeat
Option D. The simulation design that Ajay can use to estimate the probability would be Random digits Let 1,2 = rock Let 3,4,5,6,7,8,9,0 = pop select three digits. repeat.
How to find the simulation designThe number cube has being said to be made up of six digits. The digits are said to be assigned in pairs of three.
Hence we are going to have a case of 1/3. This is what can then be used to model the probability.
