If the container's height is 20 cm , the amount of water that should be added to fill it completely is 1 liter .

In the question ,

it is given that

the base area of the rectangular container is = 200 cm²

the total height of the container = 20 cm

the height at which the water if filled = 15 cm

the height of water that is needed to be filled = 20 - 15 = 5cm

So , the volume of water to be added is = base area × height

= 200 × 5

= 1000 cm³

= 1 Liter            .... because 1000cm³ = 1 Liter

Therefore , If the container's height is 20 cm , the amount of water that should be added to fill it completely is 1 liter .

Answer:

i = 7/2

ii = -7/3

Step-by-step explanation:

The line intersects one of the two axis when the vale of the other axis is 0

When x=0:

2y - 7 = 0

2y = 7

y = 7/2

When y = 0

-3x - 7 = 0

-3x = 7

x= -7/3

The function has a maximum value of 30 at x = 3.

Given Function:

f(x) = -3+18x+3

here a = -3 , b = 18 , c = 3

a is negative so it has maximum value

x = -b/2a

= -18/2*(-3)

= -18/-6

= 18/6

= 3

f(x) = -3* + 18*3 + 3

= -3*9+54+3

= -27+54+3

= 27+3

= 30

The translation T due to the transformation is (5,3)

Translation can be defined as movement in a straight line

Given the rule: (x,y) → (x + 3, y + 1) as seen in the image. That means  (x,y) translated to (x + 3, y + 1). This is what we use to solve this problem.

From the figure, the value of  (x, y) can be read i.e. (x, y) = (2,2)

Thus the translation will be:

(x,y) → (x + 3, y + 1)

(2,2) → (2 + 3, 2 + 1) = (5, 3)

Therefore, the  translation T of the transformation shown in the graph is (5, 3)

The distance driven in city is 386.4 miles and same in highway is 213.6 miles.

Let the distance driven in city be x and driven in highway be y.

Now given that the mileage in city is 46 miles per gallon and in highway same is 51 miles per gallon.

The car is driven 621 miles in 13 gallon.

So suitable system of linear equations in two variables to solve this is,

x+y = 621 ……(1)

x/46+y/51 = 13 …….(2)

From (2) we get,

51x+46y = 30498

5x+46(x+y) = 30498

5x+46*621 = 30498

5x = 30498-28566

5x = 1932

x = 386.4

So from (1) we get,

y = 621-x = 621-386.4 = 213.6

Hence the car drove 386.4 miles in city and 213.6 miles in highway.

σ = standard distribution (1.5)

The likelihood that a male's foot measures between 10 and 12. 5 inches.

P(10 < x < 12.5)

For x = 10

z = (10 - 11) / 1.5

z = -0.67

check the p-value fro z score table.

p (z = -0.67) = 0.2514

For x = 12.5

z = (1.5 - 11)/1.5

z = 1

p (z = 1) = 0.8413

P(10 < x < 12.5)  = 0.8413 - 0.2514

Sherry needs to invest 2000$ in mutual fund and 13200$ in bond to earn 548$ at the end of the year.

A percentage is just one of the many ways that a number, ratio, or fraction can be expressed. It is a number or ratio expressed as a fraction of 100.

Given:

Sherry has 15200$ to invest in mutual funds and in bonds.

Sherry has selected a mutual fund that earns 1% a year and a bond that earns 4% a year.

Here we need to find how much does she need to invest in each type of account if she wants to earn 548 at the end of the first year.

Here we have total amount = 15200$

So, let us consider x be the amount invested in mutual funds, then the amount invested in bonds will be 15200 - x.

It can be written in the following matrix

[x     15200-x ]

We know that the total amount earned at the end of the year is 548.

So, it can be written as

amount invested x percentage = final amount

[tex]\left[\begin{array}{cc}x&15200-x\\\\\end{array}\right][/tex]*[tex]\left[\begin{array}{ccc}1/100\\4/100\\\end{array}\right][/tex] = 548

We can simply it as

[x*1/100 + (15200 - x)*4/100] = 548

⇒ x/100 + 60800/100 - 4x/100 = 548

⇒ x + 60800 - 4x = 54800

⇒ -3x = 54800 - 60800

⇒ -3x = -6000

⇒ x = 2000

⇒ 15200 - 2000 = 13200

Therefore, Sherry invests 2000$ in mutual funds and 13200$ in bond to earn 548 at the end of the year.

Answer: I would say non linear. I have done problems like these before and anytime there is an exponent in the equation it always ends up being non linear. Also remember for it to be linear it most form a straight line that passes through the origin.

Step-by-step explanation:

The equation that could be used to find q is q = 110-0.15(110) where q equal the price of a quarter-page ad after the markdown.

According to the question,

We have the following information:

Cost of a quarter-page ad cost = $110

Mark down in the price = 15%

Now, q represents the price of a quarter-page ad after the markdown.

(Note that when we remove the sign of % means that the number has to be divided by 100.)

So, the equation will be the difference of the markdown price from the original price:

q = 110-(15/100)110

q = 110-0.15*110

q = 110-0.15(110)

Another possible values for a and b are a = 12 and b = 4

A variation is a relation between a set of values of one variable and a set of values of other variables

Given that:  a is inversely related to the square of b, and a = 3 when bis

8.

This can be written as:

a α 1/b²

a = k/b²               (where k is  a constant)

k = ab²

since a = 3 and b = 8.

Thus, k = 3 × 8² = 3 × 64 = 192

For a value to be another possible value for a and b, they must give k = 192 when substituted into the equation k = ab²:

a = 4, b = 12: k = 4 × 12² = 576

a = 12, b = 4: k =  12 × 4² = 192

a = 8, b = 3:  k =  8 × 3² = 72

a = 2, b = 4: k =  2 × 4² = 32

a = 6, b = 4: k =  6 × 4² = 96

The values that produce k = 192 are a = 12 and b = 4. Therefore, another possible value for a and b is a = 12 and b = 4. So option B is the answer

The equation y = (13 / 4) · x - 19 / 2 represents the perpendicular bisector of the line segment.

In this problem we need to determine the equation of the line perpendicular to a line segment whose endpoints are known. The equation of the line is represented by a first grade polynomial of the form:

y = m · x + b

Where:

And the relationship between the slopes of two perpendicular lines:

m · m' = - 1

Where:

And the slope of the original line can be found by the secant line formula:

m = Δy / Δx

And the midpoint of a line segment between two endpoints is defined below, necessary for the location of the bisector:

M(x, y) = 0.5 · A(x, y) + B(x, y)

Where:

First, find the slope of the line segment by secant line formula:

m = [- 1 - (- 5)] / (- 5 - 9)

m = - 4 / 13

Second, find the slope of the perpendicular bisector by the slope relationship between two perpendicular lines:

m' = - 1 / m

m' = - 1 / (- 4 / 13)

m' = 13 / 4

Third, determine the midpoint of the line segment by the midpoint formula:

M(x, y) = 0.5 · (9, - 5) + 0.5 · (- 5, - 1)

M(x, y) = (4.5, - 2.5) + (- 2.5, - 0.5)

M(x, y) = (2, - 3)

Fourth, find the intercept of the perpendicular bisector by means of the equation of the line:

b = y - m' · x

b = - 3 - (13 / 4) · 2

b = - 3 - 26 / 4

b = - 3 - 13 / 2
