well, √180 is about 13.4, and √72 is about 8.5, clearly 2*8.5 ≠ 13.4.

Answer:

214....

Step-by-step explanation:

If the question is : solve 4 by 216 raise to minus 2 by 3 + 1 by 256 raise to minus 3 by 4 + 2 by 243 raise to minus 1 by 5​

The given expression can be written as:

4/(216)-2/3+1/(256)-3/4+2/(243)-1/5

This expression has three terms.

Notice that the exponents are negative:

We will change the division into multiplication so that the exponents will become positive;

4*(216)^2/3+ 1*(256)^3/4+ 2*(243)^1/5

If we multiply 6 three times it will give us 6^3=6*6*6=216

If we multiply 4 four  times it will give us 4^4=4*4*4*4=256

If we multiply 3 five times it will give us 3^5=3*3*3*3*3=243

So we will write it as:

=4*(6^3)^2/3+ 1(4^4)3/4 +2(3^5)^1/5

=4(6)^2+(4)^3+2(3)

=4*36+64+6

=144+64+6

=214

Step 1: Add 1 to both sides.

y−1+1=5x+10+1

y=5x+11

Answer:

y=5x+11

Answer:

11

Step-by-step explanation:

The distance that a is to b is b-a=17-2=15.

The line segment from a=2 to b=17 has length 15.

We need to know what is 3/5 of 15.

3/5 of 15 means what is 3/5 times 15?

(3/5)(15)=3(3)=9

So this means we are looking to make a line segment that is 9 units from 2 which is 2 to 11.

So 11 is 3/5 the way from a=2 to b=17.

Let's check from 2 to 11 that is a length of 9 and from 2 to 17 that is a length of 15.

Is 9/15 equal to 3/5?

Yes, 9/15 can be reduced to 3/5.

Eq.

y = -6(x-3.7)^2 + 82.14

the value t = 3.7 represents the maximum amplitude of the rocket in-flight.

Step-by-step explanation:

The standard equation of the parabola is written as

ax^2 +bx +c = 0

But we can rewrite it in vertex form. (See attached picture.)

y = a(x-h)^2 + k

If we look at the question, we can see that the vertex is

(h,k) = (3.7 , 82.14)

y = -6(x-3.7)^2 + 82.14

the value t = 3.7 represents the maximum amplitude of the rocket in-flight.

Answer:

t = 3.7 represents the time at which the rocket will reach at the maximum height.

Step-by-step explanation:

In the diagram,

We have a downward parabola having vertex (3.7, 82.14),

Since, a downward parabola is maximum at its vertex,

That is, the maximum value of the graph is 82.14 at 3.7,

Here, the graph shows the path of a rocket,

That is, it shows the distance covered by the rocket in different time,

Hence, the maximum distance covered is 82.14 unit at 3.7 time.

Answer:

The correct answer option is: infinitely many solutions.

Step-by-step explanation:

We are given the following system of equations:

[tex] 3 x - 2 y = 6 [/tex] --- (1)

[tex] 6 x - 4 y = 1 2 [/tex] --- (2)

Dividing equation (2) by 2 to get:

[tex] 3 x - 2 y = 6 [/tex] --- (3)

As the equation (3) is same as the equation (1), therefore the system will have infinitely many solutions.

Answer:

infinitely many solutions

Step-by-step explanation:

Note that if you multiply the first equation by 2, you get 6x - 4y = 12, which is exactly the same as the second equation.  These two lines coincide, and so there are infinitely many solutions.

Answer:

C

Step-by-step explanation:

The nature of the solutions are determined by the value of the discriminant.

Given a quadratic equation in standard form ax² + bx + c = 0 : a ≠ 0

Then the discriminant is Δ = b² - 4ac

• If b² - 4ac > 0 then 2 real and distinct solutions

• If b² - 4ac = 0 then solutions are real and equal

• If b² - 4ac < 0 then solutions are not real, 2 complex conjugate solutions

Here b² - 4ac = - 6 , hence 2 complex conjugate solutions → C

Answer: Second Option

[tex]f(x)=0.25(5.25)^x[/tex]

Step-by-step explanation:

The exponential growth functions have the following form:

[tex]f(x) = a(b)^x[/tex]

Where a is the main coefficient, b is the base and x is the exponent.

For this type of functions the base b must always be greater than 1. Otherwise it would be an exponential decay function

Among the options given, the only function whose base is greater than 1 is the second option:

[tex]f(x)=0.25(5.25)^x[/tex]

Answer:

The correct answer option is B. [tex] f ( x ) = 0 . 2 5 ( 5 . 2 5 ) ^ x [/tex].

Step-by-step explanation:

If the numbers are positive along with the base of the exponent which must be greater than 1, then it an exponential growth function.

1. [tex]f(x)=6(0.25)^x[/tex]:

Here the numbers are positive but the base of the exponent is 0.25 which is less than 1 so it is not an exponential growth function.

2. [tex] f ( x ) = 0 . 2 5 ( 5 . 2 5 ) ^ x [/tex]:

Positive numbers with base of the exponent greater than 1, therefore it is an exponential growth function.

Answer:

The graph of g(x) = ㏑x translated 3 units to the right and then reflected

about the y-axis and then translated 2 units down to form the graph of

f(x) = ㏑(3 - x) - 2

Step-by-step explanation:

* Lets talk about the transformation

- If the function f(x) reflected across the x-axis, then the new

 function g(x) = - f(x)

- If the function f(x) reflected across the y-axis, then the new

 function g(x) = f(-x)

- If the function f(x) translated horizontally to the right  

 by h units, then the new function g(x) = f(x - h)

- If the function f(x) translated horizontally to the left  

 by h units, then the new function g(x) = f(x + h)

- If the function f(x) translated vertically up  

 by k units, then the new function g(x) = f(x) + k

- If the function f(x) translated vertically down  

 by k units, then the new function g(x) = f(x) – k

* lets solve the problem

∵ Graph of g(x) = ㏑x is transformed into graph of f(x) = ㏑(3 - x) - 2

- ㏑x becomes ㏑(3 - x)

∵ ㏑(3 - x) = ㏑(-x + 3)

- Take (-) as a common factor

∴ ㏑(-x + 3) = ㏑[-(x - 3)]

∵ x changed to x - 3

∴ The function g(x) translated 3 units to the right

∵ There is (-) out the bracket (x - 3) that means we change the sign

  of x then we will reflect the function about the y-axis

∴ g(x) translated 3 units to the right and then reflected about the

   y-axis

∵ g(x) changed to f(x) = ㏑(3 - x) - 2

∵ We subtract 2 from g(x) after horizontal translation and reflection

  about y-axis

∴ We translate g(x) 2 units down

∴ g(x) translated 3 units to the right and then reflected about the

   y-axis and then translated 2 units down

* The graph of g(x) = ㏑x translated 3 units to the right and then

  reflected about the y-axis and then translated 2 units down to

  form the graph of f(x) = ㏑(3 - x) - 2

Answer:

Option C (-0.922107932)

Step-by-step explanation:

Correlation is a concept which explains a linear relationship between two variables. The correlation constant lies between -1 and 1. 0 lies in the center of the interval. A negative correlation means an inverse relationship, and a positive correlation means a direct relationship. 0 technically means no linear relation between the variables. Further the correlation constant lies from 0, more the strength of the relationship. This means that closer the correlation to 1, stronger the positive relationship, and closer the correlation to -1, stronger the negative relationship. It can be seen that Option C (-0.922107932) is the correlation coefficient which is the largest in terms of the magnitude. Therefore, Option C is the correct choice!!!

The graph's y intercept would be shifted up.

The intercept of the original point is determined as follows;

y = 12x - 7, when compared to , y = mx + c

where;

c is the intercept = -7

The intercept of the second graph is determined as follows;

y = 12x + 1

New intercept = 1

The graph's y intercept will move from -7 to +1, thus, It would be shifted up.

Learn more about intercept here: https://brainly.com/question/1884491

Final answer:

The graph of the new function y = 12x + 1 would not be steeper or less steep than the original but would be shifted up compared to the graph of y = 12x - 7.(Option C)

Explanation:

Changing the equation from y = 12x - 7 to y = 12x + 1 does not alter the slope of the line, which remains 12 in both cases. The slope of a line represents the steepness and direction of the line, and since the slope (the coefficient of x) has not changed, the steepness and direction of the line will remain the same.

The change that does occur involves the y-intercept. The original line has a y-intercept at -7, while the new equation has a y-intercept at +1. This means the entire line is shifted vertically upwards by 8 units (from -7 to +1). Therefore, the correct answer to how the graph of the new function would compare with the original is that it would be shifted up.

Step-by-step answer:

APY (annual percentage yield) is the amount of interest in percent one would actually earn by investing a sum of money in a year.

It takes into account the interest rate expressed in any particular form, and the compounding period.

In the current market, most interest rates (for example, credit cards) are expressed in APR (Annual percentage rate) which is an underestimate of the actual amount to be paid, by NOT taking into account the compounding period, monthly (instead of annually) most of the time.  The shorter compounding period increases the APY.

Here the APR is 4.4%.  to take into account the compounding period, we divide the interest rate by 12 to give the monthly rate, 4.4%/12=0.044/12.

This rate will then be compounded 12 times to give the APY, or the future value after 12 months.

Future value = (1+0.044/12)^12 = 1.044898

Therefore the APY is 1.044898 less initial deposit, or

1.044898-1 = 0.044898, or 4.4898%, or 4.49% (rounded to 2 decimal places)

Answer:

D

Step-by-step explanation:

Answer:

[tex]a_n=-7+4(n-1)[/tex]

or

[tex]a_n=-7+(n-1)(4)[/tex]

Step-by-step explanation:

-7,-3,1,5,... is a arithmetic sequence.

Arithmetic sequences have a common difference. That is, it is going up by 4 each time.

When you see arithmetic sequence, you should think linear equation.

The point-slope form of a line is [tex]y-y_1=m(x-x_1)[/tex].

m is the common difference, the slope.

Any they are using the point at x=1 in the point slope form.  So they are using (1,-7).

So let's put this into our point-slope form:

[tex]y-(-7)=4(x-1)[/tex]

[tex]y+7=4(x-1)[/tex]

Subtract 7 on both sides:

[tex]y=-7+4(x-1)[/tex]

So your answer is

[tex]a_n=-7+4(n-1)[/tex]

The explicit formula for the sequence -7, -3, 1, 5,... is an = -7 + (n - 1)(4), which corresponds to an arithmetic sequence with a common difference of 4.

The student is looking for the explicit formula for the sequence -7, -3, 1, 5,.... To find the explicit formula for a linear sequence, we look for a pattern in the increments between successive terms. In this sequence, each term increases by 4 from the previous term (-7 + 4 = -3, -3 + 4 = 1, etc.), so the common difference is 4. Using the formula for an arithmetic sequence, which is an = a1 + (n - 1)d, where an is the nth term, a1 is the first term, n is the term number, and d is the common difference, we can find the explicit formula:

an = -7 + (n - 1)(4)

Since the common difference in the question is positive and we are adding it to the first term which is negative, it is clear that choice A is the correct formula representing the given sequence:

an = -7 + (n - 1)(4)

Answer:

The correct option is C.

Step-by-step explanation:

Lets solve each option one by one

A) 16a^2-72a+81

According to whole square formula:

a²-2ab+b² =(a-b)²

We have to take the square root of first and third term of each equation.

a² shows the first term = 16a^2

The square root of 16a^2 is 4a.. because 4 is the number which can be multiplied two times to give 16 and when we multiply a two times it gives us a².

b²  shows the third term = 81

The perfect square of 81 is 9.

2ab shows the middle term.

2ab = 2(4a)(9) = 72a

Thus we can factor it as a perfect square trinomial:

a²-2ab+b² =(a-b)²

16a²-72a+81 =(4a-9)²

B) 169x^2+26xy+y^2

a²+2ab+b² =(a+b)²

The square root of 169x² is 13x

Square root of y² is y

The middle term 26xy =2ab= 2(13x)(y)= 26xy

Thus we can factor it as a perfect square trinomial:

a²+2ab+b² =(a+b)²

169x^2+26xy+y^2 = (13x+y)²

C) x^2-18x-81

We can not factor it as a perfect square trinomial because the third term is negative.

D) 4x^2+4x+1

a²+2ab+b² =(a+b)²

The square root of 4x² is 2x

Square root of 1 is 1

The middle term 4x=2ab=2(2x)(1)= 4x

Thus we can factor it as a perfect square trinomial:

a²+2ab+b² =(a+b)²

4x^2+4x+1 = (2x+1)²

Thus the correct option is C....

Answer:

g(3)=82

g(-6)=-6632

Step-by-step explanation:

To find g(3) we are going to use synthetic division for dividing the polynomial x^5-5x^3-10x+4 by x-3.

So this means 3 goes on the outside.

Also since we are missing x^4 and x^2 term, we will need to put a 0 placeholders there.

3  |  1   0    -5    0   -10     4

   |       3     9   12    36    78

   |_____________________

      1    3     4   12    26     82

So g(3)=82

To find g(-6) we will put -6 on the outside:

-6 |  1   0    -5    0       -10     4

   |       -6   36  -186    1116  -6636

    --------------------------------------

      1    -6   31   -186    1106   -6632

So g(-6)=-6632

Answer:

A. 0.80

Step-by-step explanation:

First, you need to find the mean of the cost of Sara's lunches the first week. The mean is the 'average,' and to find the average, add all of your terms and divide by the amount of terms.

[tex]11.52+6.48+5.99+14+9.5\\18+5.99+14+9.5\\23.99+14+9.5\\37.99+9.5\\47.49[/tex]

Sarah's total cost for the first week was $47.49. Divide by your number of terms (5) for your average daily cost.

[tex]\frac{47.49}{5} =9.498[/tex]

This can be rounded to $9.50.

For the next week, Sara spent $4 more in total than the first week. So, add $4 to your total.

[tex]47.49+4=51.49[/tex]

Now, divide $51.49 by your number of terms (5) again to find your average for the second week.

[tex]\frac{51.49}{5} =10.298[/tex]

This can be rounded to $10.30.

Find the difference.

[tex]10.30-9.50=0.80[/tex]

Sara spent $0.80 more on average.

The expression 9 / 3[(18 - 6) - 22] evaluates to -0.3, following the order of operations: first compute the parentheses, then multiply, and finally divide.

To evaluate the expression 9 / 3[(18 - 6) - 22], we need to follow the correct order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Let's solve it step-by-step:

Next, multiply by 3. Since there are no explicit parentheses around the 3 and the expression, we interpret it as 3 times the result from step 1, 3 * (-10), which equals -30.

Finally, divide 9 by the result from step 2, 9 / -30. That gives us -0.3.

The final answer, after doing the calculations in the correct order, is -0.3.

Answer:

A bouquet of 12 flowers, 4 pink and 8 blue

Step-by-step explanation:

Let

x----> the number of boys

y ---> the number of girls

z ---> the number of children

we know that

x=2 boys----> equation A

z=3x-----> z=3(2)=6 children ----> equation B

z=x+y ----> equation C

substitute the value of x and the value of z in the equation C and solve for y

6=2+y

y=6-2=4 girls

so

The ratio of girls to boys is equal to

2/4=1/2

therefore

The ratio of pink flowers to blue flowers is equal to 1/2

Let

a -----> the number of pink flowers

b -----> the number of blue flowers

so

For b=9  blue carnations -----> Find the value of a

1/2=a/b

1/2=a/9

a=4.5 pink carnations ----> It doesn't make sense (must be a integer)

For b=8  blue carnations -----> Find the value of a

1/2=a/b

1/2=a/8

a=4 pink carnations ----> It makes sense

therefore

A bouquet of 12 flowers, 4 pink and 8 blue
