For the quadratic function f(x) = x2 + 6x +11:
a. Use the idea of completing the square to write it in graphing form.
Step-by-step explanation:
Make f(x) = 0
[tex] {x}^{2} + 6x + 11 = 0[/tex]
First, we move the constant term to the right hand side of the equality sign.[tex] {x}^{2} + 6x = - 11[/tex]
Then, we half the coefficient of x and square our result.[tex]( \frac{6}{2} ) ^{2} = 3 ^{2} = 9[/tex]
Now, we add the result to the both sides of the equation.[tex] {x}^{2} + 6x + 9 = - 11 + 9[/tex]
We can see that x²+6x+9 = (x+3)² {Try factorizing}Therefore,(x+3)²= -2
(x+3)²+2= 0
f(x)= (x+3)²+2
Which is the f(x) in graphing form.

Leila will run less than 25 miles this week. So far, she has run 13 miles. What are the possible numbers of additional miles she will run?
Use t for the number of additional miles she will run.
Write your answer as aninequality solved for t.
Leila will run less than 25 miles this week. This means the inequality symbol will be this: "<". Since she has already ran 13 miles, we need to plug-in a variable for the additional miles she must run. The inequality should be like this when plugged-in: 25 < 13 + t.
The final answer to your question is 25 < 13 + t.
Katie's earnings, E , for a week are given by the equation E = 18h, where H is the number of hours that Katie works during the week. If Katie works 40 hours per week for 4 weeks, how much money will she earn during the 4-week period?
Answer:
$2,880
Step-by-step explanation:
18 x 40 = 720 earned per week
720 x 4 (weeks) = 2880 earned in 4 weeks

Help please V/5 = 3/7 v=
Answer:
v = 15/7, or 2.14
Step-by-step explanation:
Find a common denominator, or multiply both denominators by each other, and well as the numerator.
v/5 = 3/7 can be written as 7v/35 = 15/35
multiplying both sides with 35, we are left with 7v = 15
v = 15/7, or 2.14

find the slope that goes through the following points
Answer:
The slope is 3
Step-by-step explanation:
The formula for slope is m = (y₂-y₁)/(x₂-x₁)
We assign
y₂ = -1y₁ = -4x₂ = 0x₁ = -1Note: You can choose any set of points as long as you assign y₂ and y₁ to y coordinates and x₂ and x₁ to x coordinates.
m = (-1+4)/(0+1) = 3/1 = 3

Answer:
36 ( or possibly sqrt (2754) )
Step-by-step explanation:
Use the Pythagorean Theorem to find the missing side (you will have to try two different times because you do not know what is missing....a leg or the hypotenuse)
27^2 + 45^2 = x^2 x = sqrt2754=52.4786 although this is one true answer, I do not think it is what the question seeks

A radar unit is used to measure speeds of cars on a motorway. The speeds are normally distributed with a mean of 90 km/hr and a standard deviation of 10 km/hr. What is the probability that a car picked at random is travelling at more than 100 km/hr?
Answer: 16%
step explanation:
100 m/hr is ONE S.D. (10) above 90
z - score = .8413 (Form Z-score chart)
means 84 % of cars are travelling less than 100 m/hr
~ 16% are traveling 100 or more

If a towns population currently at 50,000 experiences 5% growth every 10 years, what will its population be in 25 years
Answer:
56503
Step-by-step explanation:
this grows exponentialy so at the start it would be 50,000 growing by 5% every ten years. but since there is only 2 ten years in 25 years we must cut the percent in half making 2.5%
Step 1
(50,000×5%)+50,000= 52500
Step 2
(52500×5%)+52500= 55125
step 3
(55125×2.5%) +55125= 56503

Tristan's pen is 2/3 foot long. His pencil is 5/12 foot long. In feet , what is the conbined length of the pen and pencil
Answer:
13/12 or 1 1/12
Step-by-step explanation:
First you change 2/3 to 8/12 by multiply both the numerator and denominator by 4. Then, you add the numerators but DO NOT change the denominators. Therefore, your answer is 13/12 which = 1 1/12.
What is the true solution to the logarithmic equation below?
log₂ (6x)-log₂ (√x)=2
answer: x = [tex]\\ \frac{4}{9\\}[/tex]
[tex]log_{2}[/tex] (6x) - [tex]log_{2}[/tex] ([tex]\sqrt{x}[/tex]) = 2
expand the expression:
[tex]log_{2}[/tex](6x) = [tex]log_{2}[/tex] (6) + [tex]log_{2}[/tex] (x)[tex]log_{2}[/tex] ([tex]\sqrt{x}[/tex]) = [tex]log_{2}[/tex] ([tex]x^{\frac{1}{2} }[/tex])transform the expression:
[tex]log_{2}[/tex] ([tex]x^{\frac{1}{2} }[/tex]) = [tex]\frac{1}{2}[/tex] * [tex]log_{2}[/tex] (x)calculate the difference:
[tex]log_{2}[/tex] (x) - [tex]\frac{1}{2}[/tex] * [tex]log_{2}[/tex] (x) = [tex]\frac{1}{2}[/tex] * [tex]log_{2}[/tex] (x)multiply both sides by 2:
[tex]log_{2}[/tex] (6) + [tex]\frac{1}{2}[/tex] * [tex]log_{2}[/tex] (x) = 2 is now 2 [tex]log_{2}[/tex] (6) + [tex]log_{2}[/tex] (x) = 4transform the expression:
2 [tex]log_{2}[/tex] (6) = [tex]log_{2}[/tex] ([tex]6^{2}[/tex])simplify the expression:
[tex]log_{2}[/tex] ([tex]6^{2}[/tex]) + [tex]log_{2}[/tex] (x) = [tex]log_{2}[/tex] ([tex]6^{2} x[/tex])evaluate the power:
[tex]log_{2}[/tex] ([tex]6^{2} x[/tex]) = [tex]log_{2} (36x)[/tex]convert the logarithm into exponential form:
[tex]log_{2}(36x) = 4[/tex] is now [tex]36x = 2^{4}[/tex]evaluate the power:
[tex]2^{4} = 16[/tex]divide both sides by 36:

Area of triangle = 1/2 x 11 x (3+4+3) = 55 cm²
Area of rectangle = 4 x 2 = 8 cm²
Area of shaded region = 55 - 8 = 47 cm²
Look at the given triangles.
A. Write an expression in the simplest form for the perimeter of each triangle.
B. Write another expression in simplest form that shows the difference between the perimeter of the larger triangle and the perimeter of the smaller triangle.
C. Find the perimeter of each triangle when x=3
Blue: P=4x +2+7x +7+5x-4 --> 16x +9-4=16x +5
Red: P=x+3+2x - 5 + x + 7 --> 4x + 10 - 5 = 4x + 5
Difference between the perimeter:
(16x + 5) - (4x + 5) = 16x + 5 - 4x - 5 = 12x
Perimeter when x = 3
Blue : 16x + 5 ⇒ 16(3) + 5 = 48 + 5 = 53
Red: 4x + 5 ⇒ 4(3) + 5 = 12 + 5 = 17
The answers are explained in the solution.
What is perimeter?The perimeter of an object is given by adding the side lengths of the object.
Given are two triangles, we need to find their perimeters and then the difference and the value of the perimeter when x = 3,
Blue:
P = 4x +2 +7x + 7+5x-4
= 16x +9-4 = 16x +5
Red:
P = x+3+2x - 5 + x + 7
= 4x + 10 - 5 = 4x + 5
Now,
The difference between the perimeter:
(16x + 5) - (4x + 5)
= 16x + 5 - 4x - 5
= 12x
The perimeter when x = 3
Blue: 16x + 5 ⇒ 16(3) + 5 = 48 + 5 = 53
Red: 4x + 5 ⇒ 4(3) + 5 = 12 + 5 = 17
Hence, the perimeters of the given triangle are 53 and 17 respectively.
