Answer:
f(x) + g(x) = 6x^2 + 28x + 36
Step-by-step explanation:
Thirty eight
You begin to solve this by writing it like this [just as you have it].
f(x) = x^2 + 5 Now put g(x) where you see x
f(g(x)) = [g(x)]^2 + 5 Now substitute the right side of g(x) wherever you see g(x)
f(x - 4) = [x - 4]^2 + 5 Expand the brackets
f(x- 4) = x^2 - 8x + 16 + 5
f(x - 4) = x^2 - 8x + 21
=======================
Thirty Nine
f(x) = (x + 4)^2
g(x) = 5(x + 2)^2
Expand f(x)
f(x) = x^2 + 8x + 16
Expand g(x)
g(x) = 5(x^2 + 4x + 4) Remove the bracketsg(x) = 5*x^2 + 5*4x + 5*4 Perform the multiplicationg(x) = 5x^2 + 20x + 20f(x) + g(x) = x^2 + 8x + 16 + 5x^2 + 20x + 20
f(x) + g(x) = 6x^2 + 28x + 36

Maria is playing a video game. She earns 15 points when she completes level one. Each time she completes a level, she earns twice as many points as the previous level. How many points will Maria earn when she completes level eight?
Answer:
She will earn 1,920 points. PLEASE GIVE BRAINLIEST!!!
Step-by-step explanation:
Level 1 : 15 points x 2 = level 2
Level 2 : 30 points x 2 = level 3
Level 3: 60 points x2 = level 4
Level 4: 120 points x2 = level 5
Level 5: 240 points x2 = level 6
Level 6: 480 points x2 = level 7
Level 7: 960 points x2 = level 8
Level 8: 1,920 points
According to the Doppler effect, if a car with a blowing horn is moving toward you, the pitch you hear will
Answer:
If a car with a blowing horn is moving toward you, the pitch sounds higher than the actual emitted frequency.
Step-by-step explanation:
In figure,
V= speed of wave
U= speed of car
When car moving towards you, then
Car travels a distance in time T = VT
Wave travels a distance in time T = UT
From figure,
change in wavelength (λ') = VT - UT= T(V-U)
Now,
V = λ' f' (f' →frequency observed by you)
f' = V ÷ λ' = [tex]\frac{V}{T(V-U)}[/tex]
We know that
[tex]\frac{1}{T}[/tex] = f
Then,
f' = [tex]\frac{Vf}{V-U}[/tex]
f' = [tex]\frac{f}{1-\frac{U}{V} }[/tex]
Hence, we can say that
frequency increases as source moves toward you.
Answer:
B. Increase
Step-by-step explanation:
The closer together the crests, the higher the frequency (or pitch)

jacie can swim 3/4 of a mile in 3/8 of an hour.how far can she swim in one hour?
Answer:
2 miles
Step-by-step explanation:
We can use ratios to solve this problem
3/4 miles x miles
--------------- = ---------------
3/8 hours 1 hours
Using cross products
3/4 * 1 = 3/8 * x
Multiply by 8/3 to isolate x
3/4 * 8/3 = 3/8*8/3 *x
8/4 = x

Yogesh has 3 quarters, 1 dime, and 2 pennies
Answer: Yoghes has $0.87
Step-by-step explanation: We want to know the total amount of money that Yogesh has:
each quarter values 25¢, a dime values 10¢, and a penny values 1¢
(or the values can be written as $0.25, $0.10 and $0.01 respectively)
Yogesh has 3 quarters, so this means he has: 3*$0.25 = $0.75
he has 1 dime, so in dimes, he has: $0.10
he has 2 pennies, so in pennies, he has: 2*$0.01 = $0.02
If we sum up the 3 amounts, we have:
Total = $0.75 + $0.10 + $0.02 = $0.87
Paws at play made a total of $1234 grooming 22 dogs. Paws at Play charges $43 to groom each small dog and $75 for each large dog.
a. Write a system of equations that can be used to determine the number of small and large dogs that were groomed.
b. How many large dogs did Paws at Play groom?
Answer:
Answer (a):
s + l = 22 ... (i)
43s + 75l = 1234 ... (ii)
Answer (b)
9 large dogs.
Step-by-step explanation:
Paws at Play made a total of $1234 grooming 22 dogs.
Paws at Play charges $43 to groom each small dog and;
$75 for each large dog.
Let the number of small dogs be 's'
And the number of large dogs be 'l'
A system of equations will be:
s + l = 22 ... (i)
43s + 75l = 1234 ... (ii)
Solving this set of simultaneous equations by elimination, we simply multiply (i) by 43 to get;
43s + 43l = 946 ... (i)
43s + 75l = 1234 ... (ii)
Subtracting (i) from (ii) we get;
32l = 288 , l = [tex]\frac{288}{32}[/tex] = 9
So there are 9 large dogs.
A wood stove burns 4 logs in 2 hours how many logs burn in 9 hours ?
Answer:
18 logs.
Step-by-step explanation:
Since a stove burns 4 logs per 2 hours, then the stove will burn 2 logs in one hour. There fore in 9 hours the stove will burn 2*9 which is 18 logs.
4:2= 2 logs per hour
2*9=18 logs per 9 hours.
Answer:
16
Step-by-step explanation:

Each time a solid bicycle wheel turns, the bicycle travels 197cm. What is the area of the wheel?
Answer:
38809/(4pi) cm^2
Step-by-step explanation:
So the circumference of the wheel is 197. So to find the radius, we divide by 2 pi. So now we have 197/(2pi) as the radius. Now we have to find the area, so it is 38809/(4pi)
The area of the solid wheel is 3090 cm².
What are the circumference and diameter of a circle?The circumference of a circle is the distance around the circle which is 2πr.
The diameter of a circle is the largest chord that passes through the center of a circle it is 2r.
We know circumference is the distance around the circle which is 2πr.
Given, Each time a solid bicycle wheel turns, the bicycle travels 197cm.
Therefore,
2πr = 197.
r = 197/π×2.
r = 31.37 cm.
Therefore, The area of the solid wheel is,
πr².
= 3.14×(31.37)² cm².
= 3090 cm².

2x−(3x−4)=3x−5. pls solve
Answer:
x=9/4
Step-by-step explanation:
Performing the indicated multiplication, we get
2x - 3x + 4 = 3x - 5
Combining the x terms, we get -4x = -9, so that x = 9/4.
The following function is quadratic.
f(x)=(x+4)(x-6)
What is the value of the positive x-intercept of the graph of the related equation y = (x+4)(x-6)?
Answer: 6
You replace f(x) or y with 0, and then solve for x
y = (x+4)(x-6)
(x+4)(x-6) = y
(x+4)(x-6) = 0
x+4 = 0 or x-6 = 0 .... zero product property
x = -4 or x = 6
The x intercepts are -4 and 6. In this case, only 6 is the positive x intercept.
side note: The term "root" is another way to say "x-intercept"
percent of change of $49 to $149
To find the percentage change, here is what we can do:
difference/original value x 100%
The difference: 149-49 = 100
The original value:149
The percentage change:
100/149 x 100%
=67.11409...%
Therefore the answer is 67.1%(corr. to three significant figures)
Hope it helps!
The percent of change from $49 to $149 is approximately 204.08%.
To calculate the percent of change from $49 to $149, we first find the difference in the two amounts.
The difference between $149 and $49 is $149 - $49 = $100.
Then, we divide the difference by the original amount (in this case, $49) to find the change in terms of the original amount.
This gives us $100 / $49 = 2.0408.
To convert this to a percentage, we multiply by 100. 2.0408 x 100
= 204.08%.
So the percent of change from $49 to $149 is approximately 204.08%.

Bob raked 5% more leaves than Adam raked. Bob raked 357 liters of leaves. How many liters did Adam rake?
Answer:
Adam raked 340 liters
Step-by-step explanation:
Bob raked more leaves than Adam
5% more means take 100 % and add 5% = 105%
105% as a decimal is 1.05
Bob = 1.05 * Adam
We know Bob raked 357
357 = 1.05 Adam
Divide by 1.05
357/1.05 =1.05/1.05 Adam
340 = Adam
Vector u has its initial Point at (15,22) and it’s terminal point at (5,-4)
Final answer:
The position vector of vector u is (-10, -26). The magnitude of vector u is sqrt(776). The direction of vector u is 68.2 degrees.
Explanation:
The position vector of vector u can be found by subtracting the initial point from the terminal point. So, the position vector of u is (5-15, -4-22) = (-10, -26).
The magnitude of vector u can be found using the distance formula, which calculates the length of a vector. The formula is: magnitude = sqrt(x^2 + y^2), where x and y are the components of the vector. So, for vector u, the magnitude is: sqrt((-10)^2 + (-26)^2) = sqrt(100 + 676) = sqrt(776).
The direction of vector u can be found using trigonometry. The direction angle (theta) is given by tan(theta) = y/x. So, for vector u, the direction angle is: tan(theta) = (-26)/(-10) = 2.6. Converting to degrees, theta = arctan(2.6) = 68.2 degrees.
