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?

Answers

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

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 = 0

Step-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 + rSolution

The 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 vertex

Plugging in the values:

y = 3(x - 2/3)² + 14/3

Comparing 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/aSolution

Knowing the roots, put the equation as:

(x - α)(x - β) = 0x² - αx - βx + αβ = 0x² - (α+β)x + αβ = 0

Comparing this with the standard form:

ax² + bx + c = 0

Divide by a to make the constants of x² same:

x² + b/ax + c/a = 0

Now 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 1/2βSolution

The sum and the product of the roots:

α + β = -b/a = 1/3αβ = c/a = -5/3

The 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 = 0

10n - 5 - 2n + 3 and 5n - 2

whoever answers this gets 50pts pls hurry!!!!!!!!

Answers

The answer is -4n + 8 + 9n - 2. 3v + 5 - 9v + 2 = -6v +7. -6n + 3 - 2n + 2 = -8n + 5. 10n - 5 - 2n + 3 = 8n - 2.

What is a radian? How do radians relate to degrees?

Answers

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.

Jose unlocks his cellphone by placing his right thumb on a square of 1 centimeter by 1 centimeter at the center of the screen. Upon recognizing his thumbprint, the square expands outward. The cellphone unlocks when the perimeter reaches 32 centimeters, taking a total of 2.5 seconds. What is the perimeter of the square after 1.5 seconds? 16.8 centimeters 19.2 centimeters 20.8 centimeters 29.2 centimeters

Answers

Answer:

Step-by-step explanation:

We can solve this question using proportion

Perimeter of the square/Time is takes to unlock

We are told in the question that:

The cellphone unlocks when the perimeter reaches 32 centimeters, taking a total of 2.5 seconds.

Hence, the perimeter of the square after 1.5 seconds is:.x = unknown

32/2.5 = x/1.5

Cross Multiply

2.5x = 32 × 1.5

x = 32 × 1.5/2.5

x = 19.2 centimeters
