How do you solve a perfect square trinomial??
Answer:
Step-by-step explanation:
Here's an example:
x^2 + 6x + 9 = 0
First factorise it:
(x + 3)(x + 3) = 0
So the solution is x = -3 (multiplicity 2)
That is there are 2 roots both -3.
(x - 3)2 – 4 = x2 - 6x +

Find the equation of the rational function ƒ whose graph satisfies the conditions: Horizontal asymptote is y = 3, vertical asymptote is x = –5, removable discontinuity at x = 2, x-intercept is 1.
A function assigns the values. The function is f(x) = (8x - 8)/(x² + 2x).
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
A rational function has a denominator and a numerator.
Vertical asymptotes are x-values that the function approaches but never touches. By setting the denominator to zero, we may discover the vertical asymptotes.
Since the vertical asymptote is x=-2 and x=0, our denominator of the function will be
x(x+2) = x²+2x
Horizontal asymptotes are y values that the function approaches but never touches. Because the horizontal asymptote is y=0, the numerator's degree must be less than the denominator's degree. And because the x-intercept is equal to one, our numerator will be
x - 1
At the moment, The function can be assumed to be,
f(x) = (x - 1)/(x²+2x)
Next, we need to use the condition f(2)=1. If we plug in x=2, f(x) should equal 1. But we need to multiply the right side of the function by some constant C.
The condition f(2)=1 must then be applied. If we substitute x=2, f(x) should equal 1. However, we must multiply the right side of the function by a constant C.
1 = C(2 - 1)/(2²+2(2))
Solve for C.
1 = C / 8
8 = C
So the function will be
f(x) = [8(x - 1)] / [(x² + 2x)]
f(x) = (8x - 8) / (x² + 2x)
Hence, the function is f(x) = (8x - 8)/(x² + 2x).

O The speed of the car decreases from 4 mi/h to 2 mi/h in the first 3 seconds, increases to 5 mih in the next 5 seconds, and then remains at 5 mi/h for the last 10 seconds,
Answer:
Step-by-step explanation:
The explanation of the problem is shown in the attached figure.
AS shown in the graph:
At t = 0 the speed = 4 miles/h then decrease to the speed = 2 miles/h during the first 3 seconds then increased to 5 miles/h during the next 2 seconds, then it became constant at 5 miles/h for the last 5 seconds.
So, the correct option is:
A. The speed of the car decreases from 4 mi/h to 2 mi/h in the first 3 seconds, increases to 5 mi/h in the next 2 seconds, and then remains at 5 mi/h for the last 5 seconds.

Answer:
D. 5(x + 3)(x - 3)
Step-by-step explanation:
Both terms are perfect squares, therefore we will factor using the difference of squares formula;a² - b² = (a + b) (a - b)
5(x + 3)(x - 3)
5(x² - 9)
(5x² - 45)
5x² - 45
Option D is correct, the factored form of the expression 5x² - 45 is 5(x+3)(x - 3)
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is 5x² - 45
Five times of x square minus forty five
x is the variable and minus is the operator
Let us take 5 common from the expression to find the factor form
5(x² - 9)
5(x² - 3²)
Now we know that a² - b² = (a+b)(a-b)
5(x+3)(x-3)
Hence, the factored form of the expression 5x² - 45 is 5(x+3)(x - 3)

Please help I need it quick!!!! Please
Answer:
Question 1
Cost per 10,000 Popsicle sticks = $725.20
⇒ Single Popsicle stick = 725.20 ÷ 10000 = $0.07 (nearest cent)
Question 2
Cost per 1,000 motherboards = $8,730
⇒ Cost of Single motherboard = 8730 ÷ 1000 = $8.73
Cost per 10 motherboards = $100
⇒ Cost of Single motherboard = 100 ÷ 10 = $10
Difference = 10 - 8.73 = $1.27
Question 3
Create a table with the cost per 1 unit:
[tex]\begin{array}{| c | c | c | c |}\cline{1-4} \sf PART & \sf COST\:PER\:1\:of\:10 & \sf COST\:PER\:1\:of\:1000 & \sf COST\:PER\:1\:of\:10000\\\cline{1-4} \sf Motherboard & \$10.00 & \$8.73 & \$7.04 \\\cline{1-4} \sf Processor & \$5.00 & \$1.25 & \$0.63 \\\cline{1-4} \sf Popsicle & \$0.10 & \$0.09 & \$0.07 \\\cline{1-4} \sf Motor & \$4.50 & \$0.18 & \$0.04 \\\cline{1-4} \sf Sensor & \$6.30 & \$4.54 & \$3.18 \\\cline{1-4} \sf Small\:gear & \$1.00 & \$0.80 & \$0.70 \\\cline{1-4} \end{array}[/tex]
From inspection of the table, the Motor saves the most money per unit when 10,000 is bought, since the difference between the cost of 1 unit is the greatest for this part.
Question 4
Cost of 1100 motherboards
= cost of 1000 + cost of 10 x 10
= 8730 + 100 x 10
= 8730 + 1000
= $9,730
Question 5
Cost of 12050 sensors
= cost of 10000 + cost of 1000 x 2 + cost of 10 x 5
= 31752 + 4536 x 2 + 63 x 5
= 31752 + 9072 + 315
= $41,139

Let
Asians - a, Africans - b, Europeans - c, Americans - dEqautions as per question
Combined, there are 182 Asians, Africans, Europeans, and Americans in a village.
a + b + c + d = 182The number of Asians exceeds the number of Africans and Europeans by 59.
a = b + c + 59The difference between the number of Europeans and Americans is 14.
c - d = 14 ⇒ c = d + 14If the number of Africans isdoubled, their population exceeds the number of Europeans and Americans by 16
2b = c + d + 16 ⇒ 2b = d + 14 + d + 16 ⇒ 2b = 2d + 30 ⇒ b = d + 15Substitute a, b and c into the first equation and solve for d
(b + c + 59) + b + c + d = 182d + 15 + d + 14 + 59 + d + 15 + d + 14 + d = 1825d + 117 = 1825d = 182 - 1175d = 65d = 65/5d = 13Find the other variables

What are the x-intercepts of the graph of the function y=6tan(x/2)-3?
Step-by-step explanation:
[tex]y = 6 \tan( \frac{x}{2} ) - 3[/tex]
Set y=0
[tex]0 = 6 \tan( \frac{x}{2} ) - 3[/tex]
[tex]3 = 6 \tan( \frac{x}{2} ) [/tex]
[tex] \frac{1}{2} = \tan( \frac{x}{2} ) [/tex]
[tex] \tan {}^{ - 1} ( \frac{1}{2} ) + \pi = \frac{x}{2} [/tex]
Multiply both sides by 2
[tex]2 \tan {}^{ - 1} ( \frac{1}{2} ) + 2\pi = x[/tex]
So the x intercepts of the function is

You wish to buy a new set of strings for your guitar. You phone five different
music shops and obtain a quote for a set of strings from each of them. The
average price charged by the five music shops is R225,00. If the first two music
shops both charge R180,00 for the strings, while the third and fourth shops
respectively charge R280,00 and R270,00, how much did the fifth music shop
charge for the strings?
Answer:
215,00.
Step-by-step explanation:
Average price = 22500
18000*2 + 28000 + 27000 + x = 22500*5
91000 + x = 112500
X = 21500
Answer:
R215,00
Step-by-step explanation:
Let x = amount the 5th music shop charges for the strings
[tex]\sf mean=\dfrac{\textsf{sum of all the numbers}}{\textsf{amount of numbers}}[/tex]
[tex]\implies \sf 225=\dfrac{180+180+280+270+x}{5}[/tex]
[tex]\implies \sf 225\cdot 5=910+x[/tex]
[tex]\implies \sf 1125=910+x[/tex]
[tex]\implies \sf x=1125-910[/tex]
[tex]\implies \sf x=215[/tex]
Therefore, the fifth music shop charged R215,00 for the strings.

May runs 10/4 miles everyday .Beth runs 5/2 miles everyda.who runs further?
Explanation:
The fraction 5/2 turns into 10/4 when you multiply top and bottom by 2
5*2 = 10
2*2 = 4
Or you could use long division or a calculator to notice that
5/2 = 2.5
10/4 = 2.5
Both result in the same exact decimal value, so the fractions must be equal. Each person runs exactly 2.5 miles everyday.
