Answer:
No real solutions
Step-by-step explanation:
0=x^2+6x+13
Step 1: Subtract x^2 from both sides.
0−x^2=x^2+6x+13−x^2
−x^2=6x+13
Step 2: Subtract 6x from both sides.
−x^2−6x=6x+13−6x
−x^2−6x=13
Step 3: Since the coefficient of -x^2 is -1, divide both sides by -1.
−x^2−6x/−1 = 13/−1
x^2+6x=−13
Step 4: The coefficient of 6x is 6. Let b=6.
Then we need to add (b/2)^2=9 to both sides to complete the square.
Add 9 to both sides.
x^2+6x+9=−13+9
x^2+6x+9=−4
Step 5: Factor left side.
(x+3^)2=−4
Step 6: Take square root.
x+3=±√−4
Step 7: Add -3 to both sides.
x+3+−3=−3±√−4
x=−3±√−4
Cailen has 2 hours to drive to her friend’s house and work on some assignments. Each assignment takes an average of 18 minutes, and it takes Cailen 10 minutes to drive to the house. What inequality describes this? How many assignments can Cailen complete?
Answer:
Cailen can complete at least 6 assignments.
Step-by-step explanation:
Given that:
Time Cailen have = 2 hours = 2*60 = 120 minutes
Time taken to drive to house = 10 minutes
Time left for assignments = 120 - 10 = 110 minutes
Time taken on one assignment = 18 minutes
Let,
x be the number of assignments.
18x + 10 ≤ 120
18x ≤ 120-10
18x ≤ 110
Dividing both sides by 18
[tex]\frac{18x}{18}\leq \frac{110}{18}\\x\leq 6.11[/tex]
Hence,
Cailen can complete at least 6 assignments.

The area of a circular plate is 625pi sqaure in. If the radius of the plate is tripled what is the new area
Answer:
5625in²
Step-by-step explanation:
Area of the plate = πr²
625π = πr²
625 = r²
r = √625
r = 25in
If the radius of the plate is tripled, then the new radius will be 3(25) = 75in
New Area = π(75)²
New Area = 5625π in²
If the radius is tripled, the new area of the plate is 5625in²

What is a triangular prism?Suppose we got a triangle. Now, strech it up so as to make a stack of triangles up above another. This new 3d object is called a triangular prism.
Usually, when we talk about triangular prism, we talk about the triangular prism, whose stack goes straight up, thus, we talk about a right triangular prism.
Given that the parameters are;
Height = 4 in
Base = 6 in
Length = 10 in

How does the graph of f (x) = |x| compare with the graph of g (x) = -1/2 |x|?
Answer:
The graph of f(x) = |x| is a v-shape and doesn't cross over the x-axis.
The graph of g(x) = -1/2|x| is still a v-shape, but it's upside-down and a bit wider. This is because of the coefficient in front of the |x|. The negative sign flips the graph of |x| and the 1/2 makes the slope smaller, therefore the graph is less steep.

Mr. Miller's farm and Mr. Newton's farm together cover 525 acres. Mr. Miller's
farm is 65 acres larger than Mr. Newton's. Find the size of each farm.
Answer:
Mr. Miller's farm is 295 acres, and Mr. Newton's farm is 230 acres.
Step-by-step explanation:
From the problem we can make the following equations.....
Let "N" be the area of Mr. Newton's farm and let "M" be the area of Miller's farm. Then.....
N + M = 525
N + 65 = M
Now substitute and get....
N + M = 525
N + N + 65 = 525
2N = 460
N = 230⇒
⇒N + 65 = M
230 + 65 = 295
Write the point-slope form of the equation of the line through the given points.
through: (4,3) and (-2,-4)
Answer:
y-3=7/6(x-4)
Step-by-step explanation:
the equation for point-slope form is y-y1=m(x-x1)
first let's find the slope (m)
the formula for slope is (y2-y1)/(x2-x1)
the given points: (4,3) and (-2,-4)
label the points:
x1=4
y1=3
x2=-2
y2=-4
now substitute into the equation
m=(-4-3)/(-2-4)
m=-7/-6
m=7/6
the slope is 7/6
now substitute the numbers into the equation for point-slope form
y-3=7/6(x-4)

The driving distance between Manchester and London is 195 miles. Faris intends to travel from Manchester to London by coach. The coach will leave manchester at 3:30.
Question:
The driving distance between Manchester and London is 195 miles. Faris intends to travel from Manchester to London by coach. The coach will leave Manchester at 3:30 pm. Faris assumes that the coach will travel at an average speed of 50 mph; using his assumption workout Faris’s arrival time in London
Answer:
[tex]Arrival = 7:24pm[/tex]
Step-by-step explanation:
Given
[tex]Distance = 195\ miles[/tex]
[tex]Speed = 50mi/hr[/tex]
[tex]Take\ off = 3:30\ pm[/tex]
Required
Determine the time of arrival
First, we need to calculate the time to complete the journey.
[tex]Speed = \frac{Distance}{Time}[/tex]
Make Time the subject
[tex]Time= \frac{Distance}{Speed }[/tex]
Substitute values for Distance and Speed
[tex]Time= \frac{195mi}{50mi/hr}[/tex]
[tex]Time= 3.9hr[/tex]
The arrival time is:
[tex]Arrival = Take\ off + Time\ Taken[/tex]
[tex]Arrival = 3:30pm + 3.9\ hours[/tex]
Split
[tex]Arrival = 3:30pm + 3\ hours + 0.9\ hours[/tex]
[tex]Arrival = 6:30pm + 0.9\ hours[/tex]
Convert 0.9 hours to minutes
[tex]Arrival = 6:30pm + 0.9 * 60\ mins[/tex]
[tex]Arrival = 6:30pm + 54\ mins[/tex]
[tex]Arrival = 7:24pm[/tex]

2 = f/8 Solve the equation.
Answer:
f = 16
Step-by-step explanation:
Isolate the variable, f. Note the equal sign, what you do to one side, you do to the other. Multiply 8 to both sides of the equations:
2 = (f/8)
2(8) = (f/8)(8)
f = 2 * 8 = 16
f = 16 is your answer.

Answer:
f= 16
Step-by-step explanation:
multiply by 8 on both sides

When Pico writes articles for an adventure magazine, he gets paid by the word. For a 1,300-word article, he earned $780. How much would Pico earn for a 1,950-word article?
Answer:
Earning for 1950- word article = $1170
Step-by-step explanation:
Given that:
Amount paid for 1300 word article = $780
Ratio of words to money = 1300 : 780
Let,
x be the amount for 1950 words.
Ratio of words to money = 1950 : x
As the relationship is proportional
1300 : 780 :: 1950 : x
Product of mean = Product of extreme
780 * 1950 = 1300x
1300x = 1521000
Dividing both sides by 1300
[tex]\frac{1300x}[1300}=\frac{1521000}{1300}\\x=1170[/tex]
Hence,
Earning for 1950- word article = $1170
The distance between Maritza's house and her school is 12.5 kilometers. The bus stop is 11.75 kilometers from school. How many meters must she walk to the bus stop?
Answer: She must walk 750 meters to bus stop.
Step-by-step explanation:
Given: Distance between Maritza's house and her school (A)= 12.5 kilometers. (Total distance)
Distnance between Bustop and school (B)= 11.75 kilometers
Distance she need to walk to reach bus stop = A - B
= 12.5 - 11.75 kilometers
= 0.75 kilometers
= 0.75 x 1000 meters [ 1 kilometer = 1000 meters]
= 750 meters
Hence, She must walk 750 meters to bus stop.
What is the direct variation equation if f(x) varies directly with x and f(x)=−18 when x = 3?
A) f(x)=−15x
B) f(x)=−3x
C) f(x)=−16x
D) f(x)=−6x
Answer:
your answer is B becausewe can find k when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = - 3.
Answer:
The answer is C, I just took the quiz in CAVA :))
FYI: C is f(x)=−1/6x not f(x)=−16x
Julain has 200ml of 35% hand sanatizer. Sarah has 150ml of 85% hand sanatizer. They mix the sanatizers together in an effort to acheive 60% concentration. 1) How many milliliters of pure alchol are in the new mixture? 2) How many mililliters of water are in the new mixture? 3)What is the concentration of alchol in the new mixture?(Round your answer to one decimal place)
Answer:210ml, 140 ml, 60%
Step-by-step explanation:
Given
Juli has 200 ml of 35% hand sanitizer
Sarah has 150 ml of 85% hand sanitizer
The mixture has 60% con. i.e. 60 % is Alcohol and 40 % water
The final volume of the mixture =200+150=350 ml
Now, 60% of 350 ml= [tex]350\times 0.6=210\ ml[/tex]
So, pure Alcohol is 210 ml
Water in the final mixture= [tex]350\times 0.4=140\ ml[/tex]
The concentration of Alcohol is 60%
