Answer 20 and 21
Answer:
20. The vertex is (2/3, 14/3) | p = 3, q = -2/3 and r = 14/321. 20x² + 2x - 3 = 0Step-by-step explanation:
20.
Giveny = 3x² - 4x + 6To findThe least value of the y and the corresponding value of xConstants p, q and r such that 3x² - 4x + 6 = p(x + q)² + rSolutionThe given is the parabola with positive a coefficient, so it opens up and the minimum point its vertex.
The vertex has x = -b/2a and corresponding y- coordinate is found below:
x = - (- 4)/2*3 = 2/3, and y = 3(2/3)² - 4(2/3) + 6 = 4/3 - 8/3 + 6 = 14/3So the vertex is (2/3, 14/3)The vertex form of the line has the equation:
y = a(x - h)² + k, where (h, k) is the vertexPlugging in the values:
y = 3(x - 2/3)² + 14/3Comparing with p(x + q)² + r, to find out that:
p = 3, q = -2/3 and r = 14/3=====================================

(i) α and β are the roots of: ax² + bx + c = 0
Show that:
α + β = -b/a and αβ = c/aSolutionKnowing the roots, put the equation as:
(x - α)(x - β) = 0x² - αx - βx + αβ = 0x² - (α+β)x + αβ = 0Comparing this with the standard form:
ax² + bx + c = 0Divide by a to make the constants of x² same:
x² + b/ax + c/a = 0Now comparing the constants:
- (α+β) = b/a ⇒ α+β = - b/aαβ = c/a--------------------------------------------
(ii)
Givenα and β are the roots of: 3x² - x - 5 = 0To Find The equation with roots 1/2α and 1/2βSolutionThe sum and the product of the roots:
α + β = -b/a = 1/3αβ = c/a = -5/3The equation is:
(x - 1/2α)(x - 1/2β) = 0x² - (1/2α + 1/2β)x + 1/(2α)(2β) = 0x² - (α + β)/(2αβ)x + 1/4αβ = 0x² - (1/3)/(2(-5/3))x + 1/(4(-5/3)) = 0x² + 1/10x - 3/20 = 020x² + 2x - 3 = 0Can -8 8/15 be simplified? (Answer with yes or no) if it can what number would it be simplified?

no

What is a radian? How do radians relate to degrees?
Answer:
Radians are used to measure angles. ... A 360 degree angle is the same as a 2pi radian angle. Radians start being used in geometry and trig as you start using the unit circle. I think marking them in the unit circle is a good way to visualize how they work, and how they can be a good unit to work with in that context.
Step-by-step explanation:
mark me big brain
Answer:a radian is a angle made by taking the radius and wrapping it round the circle and
they relate to degrees because Degrees measure angles by how far we tilted our heads. ... or angle in radians
Step-by-step explanation: The angle made by taking the radius and wrapping it round the circle

Wacky Wizards offers beginner Advanced magic classes. the beginner costs 6 more than half the cost of the advanced class. Last week they taught 7 beginner classes and 11 advanced classes and earned $390. Write a system that represents the cost of the beginner class, b and the cost od advanced class, a
Answer:
if you’re looking for a equation it could be “ 24c + 15 = 687 “Step-by-step explanation:
Beginner courses cost $18 while advanced courses cost $24.
Let b represent the cost of the beginner classes and a represent the cost of advanced classes.
The beginner costs 6 more than half the cost of the advanced class. Hence:
b = a/2 + 6
2b = a + 12
2b - a = 12 (1)
Last week they taught 7 beginner classes and 11 advanced classes and earned $390, Hence:
7b + 11a = 390 (2)
Solving equations 1 and 2 simultaneously gives: b = 18, a = 24
Beginner courses cost $18 while advanced courses cost $24.

Yolanda is planning to put a pool in her backyard. The scaled model below gives the reduced measures for diameter and depth. The diameter of a pool is 18 centimeters and the depth is 4 centimeters. Not drawn to scale The yard space is large enough to have a pool that has a diameter of 27 feet. If Yolanda wants to keep the pool in proportion to the model, what will be the depth of the pool?
Answer: 6 feet
Step-by-step explanation:
You can use the ratio of the depth to the diameter of the pool in the scale to find out the depth in the yard given the diameter in the yard.
The ratio of the depth to the diameter is;
= 4/18
Given a diameter of 27 feet in the yard, the depth in the yard will be;
= 4/18 * 27
= 6 feet
Answer:
6ft
