The derivative of the function is f'(s) = 9s^2 + 2 and the values are 146 and 11
How to determine the derivative of the functionsFrom the question, we have the following parameters that can be used in our computation:
f(s) = 3s^3 + 2s
Differentiate the function
So, we have
f'(s) = 9s^2 + 2
When the values are evaluated, we have
f(-4) = 9(-4)^2 + 2 = 146
f(-1) = 9(-1)^2 + 2 = 11
Hence, the values are 146 and 11

Find:
we have to find the values of cotangent, cosine and secant at theta.
Explanation:
we know,
\(\begin{gathered} cos\theta=\frac{Base}{Hypotenuse}=\frac{6}{11} \\ sec\theta=\frac{1}{cos\theta}=\frac{1}{\frac{6}{11}}=\frac{11}{6} \\ tan^2\theta=sec^2\theta-1=\frac{121}{36}-1=\frac{85}{36} \\ cot^2\theta=\frac{1}{tan^{^2}\theta}=\frac{1}{\frac{85}{36}}=\frac{36}{85} \\ cot\theta=\pm\sqrt{\frac{36}{85}} \end{gathered}\)since, angle is less than 90 degree, so we will take only positive value of cotangent,
Therefore, the required values are given as below
\(\begin{gathered} cot\theta=\sqrt{\frac{36}{85}} \\ cos\theta=\frac{6}{11} \\ sec\theta=\frac{11}{6} \end{gathered}\)

A car travels 75 miles per hour, and a plane travels 15 miles per minute. How far (in miles) does the car travel while the plane travels 600 miles?
Answers
Answer: 50 miles
Step-by-step explanation:
600 / 15
= 40
It takes 40 minutes for the plane to go 600 miles
40 minutes is 40 / 60 hours which is 2 / 3
75 * (2 / 3)
= 50
The car travels 50 miles

Find the area of the shape shown below.
Answers
Answer: 10
Step-by-step explanation:
To work out the area of this shape you have to split this into 1 square and 2 triangles.
The formula of the area of the triangle is base x height divided by 2
The first triangle on the left would be 2x2/2=2
The area of second triangle on the left is 4x2/2=4
The formula for the square is base x height.
Then to work out the area of the square you do 2x2=4
So, to work out the area of the whole shape you add all of the areas together.

The given expressions are:
A: 3(x+2)
B: 3x+6
When two expressions are equivalent, it doesn't matter which x-value you use, the result will always be the same, then option C and option D show that these expressions are equivalent, because we will obtain the same result, regardless of the value of x.
Now, the distributive property states:
a(x+y)=a*x+a*y
If we apply this property to expression A, we have:
3*x+3*2=3x+6
Thus, by applying the distributive property we can see that those expressions are equivalent.
The option B which says "Both expressions involve addition" does not show that these expressions are equivalent since we can have different expressions as: 4x+8, x+1, etc... and these are not equivalent.

What is the value of the expression shown below 14 1/3 - 6 5/8
Answers
Answer:
the value of the expression 14 1/3 - 6 5/8 is 185/24.
Step-by-step explanation:
To solve this problem, you can convert both mixed numbers to improper fractions, then subtract the fractions and simplify the result. Here are the steps:
1. Convert 14 1/3 to an improper fraction:
14 1/3 = (14 x 3 + 1) / 3 = 43 / 3
2. Convert 6 5/8 to an improper fraction:
6 5/8 = (6 x 8 + 5) / 8 = 53 / 8
3. Subtract the fractions:
43 / 3 - 53 / 8 = (43 x 8 - 53 x 3) / (3 x 8) = (344 - 159) / 24 = 185 / 24
So the value of the expression 14 1/3 - 6 5/8 is 185/24.

find the exact value of x. 45 degree and 10 side
Answers
Answer:
The exact value of the other leg is 10.
Step-by-step explanation:
Finding the exact value of x given a 45 degree angle and a side length of 10 can be done using trigonometry. In a 45-45-90 right triangle, the two legs are congruent and the hypotenuse is equal to the square root of 2 times the length of the legs.
Therefore, if one leg is 10, the hypotenuse is 10 times the square root of 2. To find the length of the other leg, we can use the Pythagorean theorem:
c^2 = a^2 + b^2, where c is the hypotenuse, a and b are the legs of the right triangle.
Substituting known values, we get:
(10√2)^2 = 10^2 + b^2
200 = 100 + b^2
b^2 = 100
b = 10
Therefore, the exact value of the other leg is 10.
