Find the derivative of the function. y = tan2(8θ)
Answers
Answer:
16tan(8θ)sec²(8θ)
Step-by-step explanation:
Given the question :
Find the derivative of the function. y = tan2(8θ)
y = tan²(8θ)
USing chain rule :
dy/dx = (du/dx) × (dv/du) × (dy/dv)
Let u = 8θ ; du/dθ = 8
v = tan u ; dv/du = sec²u
y = v² ; dy/dv = 2v
Hence,
(dy/dθ) × dv/du × dy/dv
8 * sec²u * 2v
Where v = tan u ; u = 8θ
8 * sec²8θ * 2tan8θ
16tan(8θ)sec²(8θ)

Its values are numerical. C. Favorite baby name is a qualitative variable. Its values are not numerical. D. Favorite baby name is a quantitative variable. Its values are not numerical.
Answers
Answer:
C. Favorite baby name is a qualitative variable. Its values are not numerical.
Color of car is a qualitative variable. Its values are not numerical.
Storage space on a computer drive is a quantitative variable. Its values are numerical.
Electrical current is a quantitative variable. Its values are numerical.
Step-by-step explanation:
A qualitative variable is a variable that is categorical and isn't numerical.
For example, your favourite baby names and colours are categorical, they cannot be measured on a numerical scale
Quantitative Variable are variables that can be measured on a numeric scale. Ordinal, interval and ratio scales are quantitative scales.
Storage space can be measured on a numeric scale e.g. the storage space has 400 GB
Electric current can be measured on a numeric scale e.g. eclectic current is 50 volts

Answer:
Paired t test
Explanation:
The paired sample t test is used to measure or compare the mean of two observations or samples by measuring each subject two times as is seen above with the gold measurement which would result in two sets or pair of samples in a statistical procedure. We observe from the question that we measure each gold with two methods and then compare result of the two methods in terms of their mean error using the paired t test.

What is 10% of 344?
Answers
Answer:
34.4
Step-by-step explanation:
10% is the same thing as 0.1 so 344 times 0.1 is 34.4
A percent (%) is equal to 1/100 (We actually don't call that 'per''cent' for no reason)
So 10% is actually 10 times % which is:
[tex]10\% \\ 10(\frac{1}{100}) \\ \frac{10}{100} \\ \frac{1}{10}[/tex]
If you get a calculator and calculate 1/10 the calculator should give 0.1
You might be taught that to get the decimal form from percent you just move the decimal point to the left twice (like 34% -----> .34) but if you do this, you are essentially dividing by 100 or multiplying by 1/100
now you know 10% is 0.1 the next thing to do is multiply it to 344.
[tex]344(\frac{1}{10}) \\ \frac{344}{10} \\ 34.4[/tex]
Answer:
34.4
Step-by-step explanation:
344 x 1/10 = 34.4

Solve 2x−1<4 and −5x−3>−3 and write the solution in interval notation. If there is no solution, type ∅.
Answers
2x - 1 < 4
First, let's add 1 to both sides.
2x < 5
Divide both sides by 2
x < 5/2 or (-∞, [tex]\frac{5}{2}[/tex])
-5x - 3 > -3
Add 3 to both sides.
-5x > 0
Divide both sides by -5
x < 0 or (-∞, 0)
The solution set of the given set of linear inequations 2x - 1 < 4 and -5x - 3 < -3 is [tex]\left ( -\infty , 0 \right )[/tex].
What are equations and inequations?Algebraic expressions can be related to each other in many ways. When two expressions are equal to each other, they are called equations and are represented with an equal sign between them (=). When two expressions are not equal, they are called inequations and are represented by non-equal signs between them (>, <, ≥, ≤).
How to solve the given question?In the question, we are asked to solve the given inequations:
2x - 1 < 4 ... (i), and -5x -3 > -3 ... (ii).
First, we will solve (i), in the following ways:
2x - 1 < 4.
or, 2x - 1 + 1 < 4 + 1 (Adding 1 to both sides of the inequation)
or, 2x < 5 (Simplifying)
or, 2x/2 < 5/2 (Dividing both sides of the inequation by 2)
or, x < 5/2 (Simplifying)
or, x ∈ [tex]\left ( -\infty , \frac{5}{2} \right )[/tex] ...(iii)
Now, we will solve (ii), in the following ways:
-5x -3 > -3.
or, -5x - 3 + 3 > -3 + 3 (Adding 3 to both sides of the inequation)
or, -5x > 0 (Simplifying)
or, -5x/(-5) < 0/(-5) (Dividing both sides of the inequation by -5, sign of the inequality reverses as we are dividing by a negative number)
or, x < 0 (Simplifying)
or, x ∈ [tex]\left ( -\infty , 0 \right )[/tex] ...(iv)
For the solution set, we need the intersection of (iii) and (iv)
[tex]\left ( -\infty , \frac{5}{2} \right )[/tex] ∩ [tex]\left ( -\infty , 0 \right )[/tex]
= [tex]\left ( -\infty , 0 \right )[/tex]
∴ The solution set of the given set of linear inequations 2x - 1 < 4 and -5x - 3 < -3 is [tex]\left ( -\infty , 0 \right )[/tex].

The coordinates of the vertices of the new triangle are A'(-1,1) ,B'(-4,3), C'(-3,6)
What is rotation?Rotation can be stated as the circular movement over the object around the center.
Rotation can be done in both directions like clockwise as well as counter clockwiseIt requires rotation implies negative magnitudeA counter clockwise turns has a positive magnitude.here, we have,
given that,
Vertices of triangle = A(1,1) , B(3,4), C(6,3)
Triangle is rotated counterclockwise about the origin 90°.
In counterclockwise rotation (x,y) becomes (-y,x)
Then
the new coordinates of triangle are A', B', C'
A(1,1) = A'(-1,1)
B(3,4) = B'(-4,3)
C(6,3) = C'(-3,6)
The coordinates of the vertices of the new triangle are A'(-1,1) ,B'(-4,3), C'(-3,6)
