Answer:
5.6 = AC
Step-by-step explanation:
We know that the length of BD is congruent to the length of AC, therefore we can say:
BD ≅ AC
4.8 * 1.6 = 3.2 * x
7.68 ≅ 3.2x
7.68 / 3.2 ≅ x
2.4 = x
Therefore length of AC would be:
3.2 + x = AC
3.2 + 2.4 = AC
5.6 = AC
Hope this helps!

P varies inversely with the
square of Q. When Q is 8, P is 9.
Find the value of P when Q is 3.
Answers
Explanation:
P varies inversely with the square of Q
P = k/Q^2
When Q is 8 and P is 9,
9 = k/8^2
9 = k/64
k = 576
When Q is 3,
P = 576/3^2
P = 576/9
P = 64
The required value of P would be 64 for the given linear relationship.
What is the linear relationship?A linear relationship is a connection that takes the shape of a straight line on a graph between two distinct variables - x and y. When displaying a linear connection using an equation, the value of y is derived from the value of x, indicating their relationship.
Given that P varies inversely with the square of Q
P = k/Q²
As per the question, if Q is 8 and P is 9,
So 9 = k/8²
⇒ 9 = k/64
Apply cross-multiplication operation,
⇒ k = 576
If Q is 3, then
⇒ P = 576/3²
⇒ P = 576/9
Apply division operation, and we get
⇒ P = 64
Thus, the required value of P would be 64.

The area of a sector created by a 120° angle is 4 pi in squaredWhat is the area of a sector created by an angle of 30°
in the same circle
Answers
Answer:
π in²
Step-by-step explanation:
We'll begin by calculating the radius of the circle. This can be obtained:
Area of sector (A) = 4π in²
Angle (θ) = 120 °
Radius (r) =?
The radius of the circle can be obtained by using the formula for calculating the area of a sector. This is illustrated below:
A = θ/360 × πr²
4π = 120/360 × πr²
4π = ⅓ × πr²
Cross multiply
3 × 4π = πr²
12π = πr²
Divide both side by π
r² = 12π / π
r² = 12
Take the square root of both side
r = √12 in
Thus, the radius is √12 in.
Finally, we shall determine the area of the sector created by 30 °. This can be obtained as follow:
Radius (r) = √12 in
Angle (θ) = 30 °
Area of sector (A) = ?
A = θ/360 × πr²
A = 30/360 × π(√12)²
A = 1/12 × 12π
A = π in²
Therefore, the area of the sector created by 30 ° us π in².

11x+x^2= 2y
Y + x = 19
Answers
Answer:
x = -15,46 thì y ≈ 34,46
x = 2,46 thì y ≈ 16,54
Step-by-step explanation:
x + y = 19 => x = 19 - y (1)
thay x = 19 -y vào phương trình 11x + x^2 = 2y ta có:
11 * (19 - y) + (19 - y)^2 =2y
=> 209 - 11y + 361 - 38y + y^2 = 2y
=> y^2 - 51y + 570 = 0
=> y ≈ 34,46 và y≈16,54
thay y ≈ 34,46 vào phương trình (1) có:
x = 19 - 34,46 = -15,46
thay y ≈ 16,54 vào phương trình (1) có:
x = 19 - 16,54 = 2,46
Answer:
Step-by-step explanation:
11x+x^2= 2y
Y + x = 19
Multiply and re-arrange second equation:
2y = 38 - 2x
Substitute into first equation:
11x + x^2 = 38 - 2x
Re-arrange:
x^2 + 13x - 38 = 0
Solve using quadratic formula:
x = (-13+(13^2-4*(-38))^(1/2))/2 or (-13-(13^2-4*(-38))^(1/2))/2
x = 2.46 or -15.46
Substitute back to solve for y:
y = 19 - 2.46 or 19 + 15..46
y= 16.54 or 34.46

Step-by-step explanation:
Using the Sine rule:

a / sin A = b / sin B

Cross multiply :
Sin B * 20 = sin 48 * 26
Sin B = (sin 48 * 26) / 20

What are periodic functions?A periodic function has a range that is determined for a fixed interval and a domain that includes all real number values.
Any function that has a positive real integer p such that f (x + p) = f (x), with all x being real values, is said to be periodic.
We know, tan = sin/cos.
Hence 1/tan = cos/sin = cot.
So, The denominator sin can not be zero, And sin is zero on π and - π.
Given, A function [tex]y = cot(x - \frac{2\pi}{3})[/tex].
At, x = - π/3.
Therefore, [tex]y = cot(\frac{\pi}{3} - \frac{2\pi}{3})[/tex].
