please solve the question
Answer:
x/2 + y√3/2 = 4
Step-by-step explanation:
Step 1: Apply formula
Formula for this problem is :-
xcosα + ysinα = p
Step 2: Substitute values
xcos(60°) + ysin(60°) = 4
x(1/2) + y(√3/2) = 4
x/2 + y√3/2 = 4
Hope it helps.

Step-by-step explanation:
find the second derivative of the given function.
[tex]f(x) = \frac{x {}^{2} + 2x - 1}{ x} [/tex]
Answer:
= -2/x^3
Step-by-step explanation:
Possible derivation:
d/dx(d/dx((x^2 + 2 x - 1)/x))
Distribute 1/x through x^2 + 2 x - 1:
= d/dx((d/dx(2 - 1/x + x)))
Differentiate the sum term by term and factor out constants:
= d/dx((d/dx(2) - d/dx(1/x) + d/dx(x)))
The derivative of 2 is zero:
= d/dx(0 - d/dx(1/x) + d/dx(x))
Use the power rule, d/dx(x^n) = n x^(n - 1), where n = -1.
d/dx(1/x) = d/dx(x^(-1)) = -x^(-2):
= d/dx(0 - -1/x^2 + d/dx(x))
The derivative of x is 1:
= d/dx(0 - -1/x^2 + 1)
Differentiate the sum term by term:
= d/dx(1) + d/dx(1/x^2)
The derivative of 1 is zero:
= d/dx(1/x^2) + 0
Simplify the expression:
= d/dx(1/x^2)
Use the power rule, d/dx(x^n) = n x^(n - 1), where n = -2.
d/dx(1/x^2) = d/dx(x^(-2)) = -2 x^(-3):
Answer: = -2/x^3

What is a conic section?A shape made up of a surface and a round cone intersecting. A conic section is sometimes a circle, an ellipse, a parabola, or a hyperbola, based on the direction of the surface with regard to the conical.
The ellipse is obtained by slicing the cone at an angle that passes through the surface of the cone.
Then the correct option is B.

100/7
Answer:
100/7 --> 50/3.5 --> 25/1.75 . If we're assuming, without a calculator, we can just say 1.75 ~ 2. So 25/2 = 12.5 as an approx .
But actually, 100/7 -- with no assumptions etc, is just 14.28571429

rahim's father's age is 3 times as old as him. if their sum is 56 , find their ages
Answer:
Rahim is 14 and his father is 42.
Step-by-step explanation:
Let F be Rahim's father's age and R is Rahim's age.
We learn that:
F = 3R [Rahim's father's age is 3 times as old as him]
and
F + R = 56 [their sum is 56]
----
We have 2 equations and two unknowns, so we should be able to find the answers.
Rearrange the second equation to: F = 56 - R
The use that definition of F in the first equation:
F = 3R
(56-R) = 3R
Then we can find R:
56-R = 3R
4R = 56
R = 14
Since R=14 and F + R = 56,
F + R = 56
F + 14 = 56
F = 42
Check
Does F=3R?
42 = 3(14)? YES
Does F + R = 56?
42 + 14 = 56? YES
Rahim is 14 and his father is 42.

Answer:
20 m
Step-by-step explanation:
Using the Pythagorean Theorem,
a² + b² = c²
c² = (16)² + (12)²
= 256 + 144
= 400
c =√400
c = 20 m
Solution:
Given:
Length of rectangle = 16 mBreadth of rectangle = 12 mSolve using Pythagoras theorem:
c (Diagonal)² = 12² + 16²=> c² = 144 + 256=> c² = 400=> c = √400 = 20 mCD bisects ∠ACB. Which statements must be true? Check all that apply.
1. AD = BD
2. AC = CD
3. m∠ACD = m∠BCD
4. m∠CDA = m∠CDB
5. m∠DCA = m∠DAC
Answer: A, C, D
Step-by-step explanation:
1) AD=BD must be true because the angle bisector drawn from the vertex angle of an isosceles triangle is the perpendicular bisector of the base.
2) AC=CD does not need to be true because angles ADC and CAD do not need to be congruent.
3) This must be true by the definition of an angle bisector.
4) This must be true because angles CDA and CDB are both right angles.
5) This does not need to be true because triangle ADC does not need to be isosceles.

The assumption that there are no exact linear relationships among the independent variables in a multiple linear regression model fails if _____, where n is the sample size and k is the number of parameters.
a. n < k 1
b. n > k
c. n
Answer:
a. n < k + 1
Step-by-step explanation:
Multiple linear regression model is used for analyzing the linear relationship between the independent variables and dependent variable. It is used when there is the need to predict the relationship of a variable based on the values of two or more other variables. These variables could be nominal, ordinal, or interval/ratio level variables.
Some assumptions of multiple linear regression analysis are:
i. There must be a linear relationship between the outcome variable and the independent variables.
ii. The residuals are normally distributed.
iii. That the independent variables are not highly correlated with each other.
The assumption that there are no exact linear relationships among the independent variables in a multiple linear regression model fails if n < k + 1.
