Answer:

2 pound bags and have a remeinder of 1/10

Step-by-step explanation:

Answer:

She can fill 2 bags for her lunch and will have 1/10 pound left.

Step-by-step explanation:

It is easier if there is a common denominator, so I made the 2/5 into 4/10, so it is the same as 9/10 pound she bought.

4/10 is one bag, and if you double that, it is 8/10 pounds used. This is two bags of raisins for her lunch.

9/10 - 8/10 leaves 1/10 pound remaining, and not in a bag.

To find the inverse function, you will have to write n in terms of c (which means number of visits as function of monthly cost).

The inverse function would be:

[tex]n = \dfrac{c-50}{4}[/tex]

Inverse function of given function.

The inverse function of f is a function of f which can remove the effect of f on its input.

Inverse is only possible if the function f is bijective (one to one correspondence, which means one input to one output uniquely and one output is connected to only one input by mapping f)

Since the given function is a linear function and not a  vertical line, thus, one input n uniquely maps to one output cost and one cost uniquely is obtained by one and only one value of n.

[tex]cost = 50 + 4n\\ 4n = cost - 50\\\\ n = \dfrac{\text{c - 50}}{4} \text{\: (assuming cost to be denoted by c)}[/tex]

Thus, we have the inverse function of given function as:

[tex]n = \dfrac{c-50}{4}[/tex]

[tex]x^2 - 2x + 10[/tex], option B

Step-by-step explanation:

Complex numbers:

The most important relation that involves complex numbers is given by:

[tex]i^2 = -1[/tex]

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

[tex]ax^{2} + bx + c, a\neq0[/tex].

This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:

[tex]x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}[/tex]

[tex]x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}[/tex]

[tex]\bigtriangleup = b^{2} - 4ac[/tex]

In this question:

The solutions are:

[tex]x_1 = 1 - 3i, x_2 = 1 + 3i[/tex]

We have to find the polynomial. All option have [tex]a = 1[/tex]. So

[tex](x - (1 - 3i))(x - (1 + 3i)) = x^2 - x(1 + 3i) - x(1 - 3i) + (1 - 3i)(1 + 3i) = x^2 - x -3ix - x + 3ix + 1^2 - (3i^2) = x^2 - 2x + 1 - 9i^2 = x^2 - 2x + 1 - 9(-1) = x^2 - 2x + 10[/tex]

The correct answer is given by option b.

Answer:

A watermelon weighs about 3 (grams /(kilograms) 3.

Step-by-step explanation:

Answer:

6,450 g

Step-by-step explanation:

Since there are 1000 grams in 1 kilogram, you multiply 6.45 kg x 1000 g.

6.45 x 1000 g equals 6,450 grams. Move the decimal 3 times to the right because there are 3 zeroes in 1000.

You always move your decimal to the right when multiplying decimals.

Answer:

a) d = 8.5 units

The distance of a line segment with end points

d = 8.5 units

Step-by-step explanation:

Step(i):-

Given points are G(4,9) and H( 7,1)

By using distance formula

   G H  = [tex]\sqrt{x_{2}-x_{1} )^{2} +(y_{2} -y_{1} )^{2} }[/tex]

Step(ii):-

[tex]d = \sqrt{7-4 )^{2} +(1-9 )^{2} }[/tex]

d = [tex]\sqrt{3)^{2} +(-8 )^{2} } = \sqrt{9+64} = \sqrt{73}[/tex]

d = 8.5 units

Answer:

B. $25.50

Step-by-step explanation:

This is a bit of a trick question.

To find how much money is taken off the price, you would do 15% (0.15) • 30 and you get $4.50. This is the discount that is taken off of the price, not the discounted price. To find the new discounted price, subtract the $4.50 from $30.00.

$30.00 - $4.50 = $25.50

Answer: 32 cm

Step-by-step explanation:

Answer:

All of the sides of the square are 8 cm. So the prementer would be 32 cms

Step-by-step explanation:

To find the sides of the square, you got to think what x what = 64. This shows you that 8 x 8 is 64. and since it is a square, all of the sides are the same. So 8+8+8+8 = 32 or you can do 8 x 4 = 32

Answer:

8,4

Step-by-step explanation:

Step 1: Find the slope of the line.

Step 2: Use the slope to find the y-intercept.

Step 3: Use steps 1 and 2 to write the answer.

I will explain these steps by looking a several examples. Please understand that there are often several

different ways to complete each math problem, but I have found through the years that students are most

successful when the do problems the same way each and every time they attempt the problem. If you

know a different way to find the answer that is great, but I am going to show how to do the problem one

way and use the same technique everytime I see this problem.

Example 1: Find the equation of the line passing through the points (–1, –2) and (2, 7).

Step 1: Find the slope of the line.

To find the slope of the line passing through these two points we need to use the slope

formula:

( )

( )

So the slope of the slope of the line passing through these two points is 3.

Step 2: Use the slope to find the y-intercept.

Now that we know the slope of the line is 3 we can plug the slope into the equation and

we get:

y = 3x + b

Next choose one of the two point to plug in for the values of x and y. It does not matter

which one of the two points you choose because you should get the same answer in either

case. I generally just choose the first point listed so I don’t have to worry about which

one I should choose.

(–1, –2) → –2 = 3(–1) + b Multiply to simplify the problem.

–2 = –3 + b Solve for b and you will have the y-intercept.

b = 1
