Answers

Answer 1
The solution to your question is a=-2. Hope this helped you. I just took the test. So I know it is right. Can you please give me Brainliest?
Answer 2

Answer:

a=-2 is extraneous solution.

Step-by-step explanation:

Given the equation

[tex]\frac{3}{a+2}+\frac{2}{a}=\frac{4a-4}{a^2-4}[/tex]

we have to find the extraneous solution.

An extraneous solution is a solution to an equation, that emerges from the process of solving the problem but is not a valid solution to the problem.

[tex]\frac{3}{a+2}+\frac{2}{a}=\frac{4a-4}{a^2-4}[/tex]

[tex]\frac{3}{a+2}+\frac{2}{a}=\frac{4a-4}{a^2-4}\\\\\frac{3a+2(a+2)}{a(a+2)}=\frac{4(a-1)}{a^2-4}\\\\\frac{5a+5}{a(a+2)}=\frac{4(a-1)}{a^2-4}[/tex]

On solving, we get

The solution is a=4 and a=-2

Here the solution a=-2 is the valid solution as it makes the denominator 0.

⇒ a=-2 is extraneous solution.

Option 1 is correct.

Factor by grouping m^2 +8mn -3mn-24n^2
20 POINTS

Answers

Group and factor the GCF, then combine (m+8n) (m-3n)
To factor this is expression, one simple way to do this is to place brackets surrounding each set of 2 terms. Do brackets around m^2 and 8mn and brackets around -3mn - 24n^2.

Then solve for the common factor in each bracket group.

m(m + 8n) - 3n(m + 8n)

(m-3n)(m + 8n) is the answer.

A company need to package hazardous chemicals in special plastic rectangular prism containers that had 80 cubic feet. Find the whole number dimensions of the container that would use the least amount of plastic.

Answers

we know that
the cube is a prism rectangular with minimum surface area
then
Volume cube=b³=80-------------> b=4.31 ft

the problem is asking me for a whole number

therefore
b=4 ft------------> I assume a rectangular prism of square base
V=b²*h--------------> h=V/b²=80/4²=5 ft

the answer is 4 ft x 4 ft x 5 ft  number dimensions of the container



To package hazardous chemicals in special plastic containers the dimensions of the container should be 4 × 4 × 5 feet.

A rectangular prism with a volume of 80 cubic feet needs to be designed to use the least amount of plastic. To do this, we need to find the dimensions (length, width, height) that, while maintaining the given volume, result in the minimum surface area.

The volume of a rectangular prism is given by:

Volume = length × width × height

For our case: length × width × height = 80 cubic feet

To minimize the surface area, the dimensions should be close to a cube as this shape has the smallest surface area-to-volume ratio. We will seek integer dimensions. The formula for the surface area (SA) of a rectangular prism is:

SA = 2(length × width + width × height + height × length)

We start by considering potential combinations of whole numbers whose product is 80:

1 × 1 × 801 × 2 × 401 × 4 × 201 × 5 × 161 × 8 × 102 × 2 × 202 × 4 × 102 × 5 × 84 × 4 × 5

Calculating the surface area for each configuration:

1 × 1 × 80: SA = 2(1×1 + 1×80 + 80×1) = 2(1 + 80 + 80) = 322 sq. feet1 × 2 × 40: SA = 2(1×2 + 2×40 + 40×1) = 2(2 + 80 + 40) = 244 sq. feet1 × 4 × 20: SA = 2(1×4 + 4×20 + 20×1) = 2(4 + 80 + 20) = 208 sq. feet1 × 5 × 16: SA = 2(1×5 + 5×16 + 16×1) = 2(5 + 80 + 16) = 202 sq. feet1 × 8 × 10: SA = 2(1×8 + 8×10 + 10×1) = 2(8 + 80 + 10) = 196 sq. feet2 × 2 × 20: SA = 2(2×2 + 2×20 + 20×2) = 2(4 + 40 + 40) = 168 sq. feet2 × 4 × 10: SA = 2(2×4 + 4×10 + 10×2) = 2(8 + 40 + 20) = 136 sq. feet2 × 5 × 8: SA = 2(2×5 + 5×8 + 8×2) = 2(10 + 40 + 16) = 132 sq. feet4 × 4 × 5: SA = 2(4×4 + 4×5 + 5×4) = 2(16 + 20 + 20) = 112 sq. feet

Thus, the dimensions 4 × 4 × 5 feet are the ones that use the least amount of plastic, giving a surface area of 112 sq. feet.

Hello there! I can help you! The first option is definitely a polynomial. It has a degree (3), a constant (value of y), and it looks like what a polynomial should. A is eliminated. B is also eliminated, because while there is no exponent, there is constand and a variable. It has a degree of 0, but it can still be called a polynomial. C has just a variable, but y is a polynomial term. It has no exponent shown, but it has no negative exponent. C is out. D is NOT a polynomial, because the squared root does not belong in a polynomial. There are no radicals or radicands allowed in a polynomial, so that expression is not a polynomial. The answer is D.

does the function y=4^-2x represent an exponential growth or decay? what is the percent rate of change?

Answers

Since it has a negative exponent, the equation [tex]y=4^-^2^x[/tex] is showing exponential decay.  The graph will decrease.  
In order to find the percent of change, we need to review our exponent properties.  The product property tells us that when we raise a power to a power, we multiply the exponents.  This means we can view our exponent of -2x as the product of two exponents, -2 and x.  This would look like
[tex]y=(4^-^2)^x[/tex].  We know that negative number exponents tell us to "flip" sides of the fraction, so that tells us that 4⁻² = 1/4² = 1/16.  We can then rewrite our equation as
[tex]y=(\frac{1}{16})^x[/tex]
Exponential decay is in the form y = a(1-b)ˣ.  From our equation, a = 1.  We know that 1-b = 1/16; this means that b must be 15/16.  Thus our percent of decrease would be 15/16 = 0.9375 = 93.75%.
Final answer:

The function y=4^-2x represents exponential decay. The percent rate of change is 6.25%.

Explanation:

The function y=4-2x represents exponential decay. In an exponential decay function, as the value of x increases, the value of y decreases. On the other hand, in exponential growth, as the value of x increases, the value of y increases.

The percent rate of change can be found by determining the decay factor, which is equal to 1 divided by the base of the exponential function raised to the power of the exponent.

In this case, the decay factor would be 4-2 = 1/16. To find the percent rate of change, we can convert the decay factor to a percentage by multiplying it by 100%, so the percent rate of change would be 1/16 * 100% = 6.25%.

a flyer on a reconnaissance flight has 4 hours for a round trip. his blade can fly 200 mph in still air. he flies out from his base against a 20 mph wind and immediately returns to his base, flying with the same wind. how many hours did he take for his fight out?

Answers

When flying with the wind, the effective plane speed is 200 + 20 = 220 mph.
When flying against the wind, the effective plane speed is 200 - 10 = 180 mph.

Let d =  the distance (miles) from his base to the destination.
The time (hours) to travel with the wind is
t₁ = d/220  
The time (hours) to travel against the wind is
t₂ = d/180

The total time taken is 4 hours, therefore
t₁ + t₂ = 4
d/220 + d/180 = 4
d(1/220 + 1/180) = 4
0.010101d = 4
d = 396 miles

Therefore
t₁ = 396/220 = 1.8 hours = 1 hour, 48 minutes (floght in)
t₂ = 396/180 = 2.2 hours = 2 hours, 12 minutes (flight out)

Answer: 2.2 hours

Team tool Bella gathered 15 pounds of wood in 1/3 of an hour. What was their speed in pounds per hour.

Answers

Team tool Bella gathered 15 pounds of wood in 1/3 of an hour.

1/3 of an hour is equal to 1/3 of 60 mins = 1/3 * 60 mins = 20 mins

We have to find their speed in pounds per hour( 60 mins).

Pounds of woods gathered in 1 hour or 60 mins = 15/20*60

= 15 * 3

= 45 pounds

Therefore, their speed in pounds per hour is 45 pounds / hour

For problem number 1:-
1)Let's assume the payment which each one of them paid are A,B,C, and D, for the 1st, 2nd, 3rd and 4th respectively.
so the total payment is the sum of all of them  
A+B+C+D= 60 ----->(eq 1)
The 1st paid 0.5 of the sum of the  other teachers payments
A= 0.5 (B+C+D) ---->(eq 2)

The 2nd paid 1/3 of the others payment
[tex] B= \frac{A+C+D}{3}[/tex] ------>(eq 3) 

The 3rd paid 1/4 of the others payment
[tex] C = \frac{A+B+D}{4} [/tex] ---->(eq 4)
we have now 4 equations in 4 unknowns.

From equation 1 and 2 :-
----------------------------------
By multiplying (eq 2) by 2 and substitute in (eq 1)
2 A = B+C+D (sub in eq 1)
A+ 2A =60
then 3A= 60
then A =$20 (The first teacher's payment)

From equations 1 and 3 :-
------------------------------------
By multiplying (eq 3) by 3
3B = A+C+D (sub in eq 1)
B+3B=60
4B=60
B= $15 (The second teacher's payment)

From equations 1 and 4:-
------------------------------------
By multiplying (eq 4) by 4
then 4 C=A+B+D (sub in eq 1)
4C+ C = 60
5C=60
C= $6 (The third teacher's payment)

By substituting the values of A,B and C in (eq 1).
20 + 15 + 6 + D=60
41+ D =60 (By subtracting both sides by 41)
D = $19.(The forth teacher's payment)

Answers

1) A series is called finite, if there is a finite number of factors that need to be added. If there are infinitely many factors (after any finite number of additions, there are still factors to add), then it is called infinite.
2) We have that this is the sup of powers of 2; but it does not take all powers of 2, only until the 8th power of 2. Hence, there are 8 summants, a finite number.
3) We have that this series involves all the natural numbers; "..." means that we should continue adding the next term, meaning that there is no end.
4) In order to find the first term of the series, we need to substitute n=1. Hence the first term is 1/(2*1+1)=1/3. Similarly, the next term is equal to 2/(2*2+1)=2/5
5) We notice that the first term is 2 and then that all the terms are 2 higher than their previous one. Hence we have that if we start summation from 1, we need to double it to get the term. This works for all and hence we have that the series is equal to: [tex]\sum_{n=1 \ n=6} 2n[/tex].
6) We have that after one, year, he gains 4%*2000, hence the final amount is 1.04*2000 after one year. Next year, this becomes the capital and we have to multiply again by 1.04. Hence, after 5 years, the total annuity value is: (1.04)^5*2000=2433$.
7) We have that the sum is 4+7+... up until 3*12+1=37. The sum of those is 246 or else we can have that it is equal to 3* n(n+1)/2+12 where n=12 (The sum of all numbers from 1 to n is given by n*(n+1)/2 )

The angle is 127°, so the Pythagorean theorem does not apply.

Generally, you would use the Law of Cosines to solve for the third side when given two sides and the angle between them.

EF^2 = 7^2 +15^2 -2*7*15*cos(127°)
EF ≈ √(400.3812) ≈ 20.00953

My guess is that you're expected to use 20 for the length of the 3rd side.

By Heron's formula, s = (7 +15 +20)/2 = 21

Area = √(21*(21 -7)*(21 -15)*(21 -20)) = √(21*14*6*1) = √1764 = 42 . . . . yd^2

Therefore, the common ratio is given by

r = -3.

Thus, the required common ratio of the given geometric sequence is -3.

help me please ASAP !!!!!

You want k such that
.. (10 +k)/2 = 7
Multiplying by 2, we have
.. 10 +k = 14
Then
.. k = 14 -10
.. k = 4

Can someone tell me if the answer is correct?

Your answer is not correct
3 / ((3√5) + 4)
3 x ((3√5) - 4) / ((3√5) + 4) x ((3√5) - 4)
((9√5) - 12) / (45 - 16)
((9√5) - 12) / 29 is the correct answer
