A new bank customer with ​$4,500 wants to open a money market account. The bank is offering a simple interest rate of 1.5​%.

Answer:

x=2

Step-by-step explanation:

First you put the equations in the form of y = mx + b

Then once they are like that it would look like:

y = -2x + 6

y = 3x - 4

So then you can set them equal to each other and it will look like this:

-2x + 6 = 3x - 4

Then you add 2x to both sides and get:

6 = 5x - 4

Next, add 4 to both sides and get:

10 = 5x

So then you will simplify by dividing both sides by 5 and getting:

2 = x

To find the volume of the solid generated by revolving the plane region about the line x using the shell method, we need more specific information about the given plane region and the boundaries of integration.

The shell method is a technique used to calculate volumes of solids of revolution. It involves integrating cylindrical shells along the axis of rotation. However, in order to apply the shell method, we require additional details regarding the given plane region and the boundaries of integration.

Typically, the plane region is defined by a function or an equation. For example, if the plane region is bounded by the curves y = f(x), y = g(x), and the line x = a, x = b (where f(x) > g(x) for all x in the interval [a,b]), we can proceed with the shell method.

To calculate the volume using the shell method, we integrate the circumference of each cylindrical shell multiplied by its height. The differential height is given by Δh = f(x) - g(x), and the differential circumference is 2πx.

The integral expression for calculating the volume using the shell method is:

V = ∫[a,b] 2πx * (f(x) - g(x)) dx

By evaluating this integral over the appropriate interval [a,b], we obtain the volume of the solid generated by revolving the given plane region about the line x.

However, without specific information about the plane region, the equations or functions defining it, and the boundaries of integration, it is not possible to provide a numerical value for the volume. If you can provide more details or specify the plane region, I would be happy to assist you further in using the shell method to determine the volume.

Step-by-step explanation:

Q = 7m + 3n,

R = 11 - 2m,

S = n + 5,

T = -m - 3n + 8.

R - S + T = 11 - 2m - (n + 5) + (-m - 3n + 8)

R - S + T = 11 - 2m - n - 5 - m - 3n + 8

R - S + T = 14 - 3m - 4n

R - S + T = -3m - 4n + 14

The equation of the line which passes through the coordinates (0,0) and (3.5,3.5) is y = x.

The slope intercept form of a line is given by:-

y = mx + c

Where,

m represents the slope of the line

c represents the y -intercept

(x,y) represents the coordinates of each point on the line.

We also know the slope of the line will be:-

(3.5-0)/(3.5-0) = 3.5/3.5 = 1

Hence, m = 1

Putting (0,0) in y = mx + c, we get,

Answer: 1/3

Step-by-step explanation: The ratio of multiplication problems to total problems is 12:36, which can be simplified to 1:3.

Answer:

A

Step-by-step explanation:

Hi there.
We know this math exam has 12 multiplication and 24 division problems, making the overall exam questions 36 problems. (12+24=36)

The ratio is the fraction equivalent comparison between two variables. In this case, it's multiplication problems over total problems.

We know multiplication problems as 12, and we calculated the total, which is 36.

The answer would be 12/36; but it's divisible by 12 and can be further simplified to 1/3.

Answer:

b

Step-by-step explanation:

first you have to turn each equation into standard form

so...

a) 3y - 12 = 4x

add 12 to both sides

3y = 4x + 12

divide everything by 3

y = 4/3x + 4

b) 4y - 12 = 3x

add 12 to both sides

4y = 3x + 12

divide everything by 4

y = 3/4x + 3

c) 3y + 12 = 4x

subtract 4 from both sides

3y = 4x - 12

divide everything by 3

y = 4/3x - 4

d) 4y + 12 = 3x

subtract 12 from both sides

4y = 3x - 12

divide everything by 4

y = 3/4x - 3

then look at the graph

find the y intercept first (which is the last number in the equations)

so...

a) 4

b) 3

c) -4

d) -3

the line meets a 3 on the y axis so the y intercept is 3 so you can already tell the answer is b.

but to check yourself you would see that the points is up 3 over 4 so 3/4 is the slope so thats the number infront of x.

FIFO: March 16 - Accounts Receivable 21,250, Sales Revenue 21,250, Cost of Goods Sold 13,750, Inventory 13,750.

LIFO: March 16 - Accounts Receivable 21,250, Sales Revenue 21,250, Cost of Goods Sold 14,500, Inventory 14,500.

The FIFO inventory valuation method assumes that the items purchased first are sold first. Therefore, for the March 16 sale, we need to record the cost of goods sold using the cost of the oldest units still in inventory. In this case, since 550 units were purchased on January 1 and 350 units were purchased on February 5, the cost of goods sold would be calculated based on the cost of the 250 units from the January 1 purchase, which amounts to SAR 13,750. The corresponding entry reduces the inventory and records the cost of goods sold.

The LIFO inventory valuation method assumes that the items purchased last are sold first. Thus, for the March 16 sale, we need to record the cost of goods sold using the cost of the most recent units purchased. Since 350 units were purchased on February 5, the cost of goods sold would be calculated based on the cost of these units, which amounts to SAR 14,500.

The required value of a + b is 35.

The area of the shadow can be calculated by finding the area of the regular hexagon. The formula for the area of a regular hexagon is:

    A = (3√3)/2 * s^2,

where s is the length of one side of the hexagon.

Since the cube is balanced on one of its vertices, the length of one side of the hexagon is equal to the length of one edge of the cube, which is 8.  Therefore, the area of the shadow is A = (3√3)/2 * 8^2 = 64√3/2 = 32√3.

The value of a is 32 and the value of b is 3, so the value of a + b is 32 + 3 = 35. Therefore, the answer is 35.

Step-by-step explanation:

sin x + cos x = 90

5x + 3x +10 = 90

x = 10

Answer:

Explanation:

Given 4x + 6y - 10x + 13y = 11

If (1, 1) is a solution, then substituting x = 1 and y = 1 into the left hand side of the equation gives 11.

Doing this, we have:

4(1) + 6(1) - 10(1) + 13(1)

= 4 + 6 - 10 + 13

A 11.544 acre-feet of this ice field will melt from the beginning of day 1 (t = 0) to the beginning of day 4 (t = 3). So, correct option is C.

To solve the problem, we need to integrate the given rate of melting with respect to time over the interval [0,3] to find the total amount of ice that melts during this time.

First, we can simplify the given rate of melting by using the identity: sin³(t) = (3sin(t) - sin(3t))/4

So, M(t) = 4 - (3sin(t) - sin(3t))/4 = 16/4 - 3sin(t)/4 + sin(3t)/4 = 4 - 0.75sin(t) + 0.25sin(3t)

Integrating this expression with respect to t over the interval [0,3], we get:

\(\int\limits^3_0\) M(t) dt = \(\int\limits^3_0\) (4 - 0.75sin(t) + 0.25sin(3t)) dt

= [4t + 0.75cos(t) - (1/3)cos(3t)]|[0,3]

= (12 + 0.75cos(3) - (1/3)cos(9)) - (0 + 0.75cos(0) - (1/3)cos(0))

= 11.544

Therefore, the answer is (C) 11.544.

The order of the steps for the bisection of line segment AB will be D, E, B, C, and A.

The first thing we do for bisecting any line segment is to take up a distance of more than the approximate half of the line segment and place the compass on either point of the line.

Hence the first point will be D. Place the compass on point A and open it wider than half the distance of the segment.

Since an arc on both sides of the segment has to be drawn, the next point will be E. Swing an arc above and below the segment.

Since the same thing has to be repeated for the other point, the next point will be B. Keeping the compass the same width, place the compass on point B, and swing an arc above and below the segment.

Now we have got 2 points above and below the line segment, the next point has to be C. Place points C and D on the intersection of the arcs created above and below segment AB.

The line intersecting these points and AB has to be the point that divides AB in half, and the last point will be A. Draw a line from point C to point D.

To find the amount of gold needed for gold plating a brick, total surface area of the brick would be needed to be calculated, assuming the brick is cuboid or cube shaped.

While dealing with cubes and cuboids, we should know how to find the surface areas and volumes of the two objects. When we either fill these or talk about all the three dimensions of an object, we talk about the volume of the said object. And, when we paint or talk about just the exterior or interior walls of an object, we talk about the surface area of the said object.

When all the six faces of a cube or a cuboid are used, we calculate surface area for all the faces and this is called the total surface area.

Let us look at the different formulas to calculate volume and total surface area of a cube and a cuboid,

Total surface area of a cube (side \(a\)) =  6 × (area of each face)  

                                                          = 6 × \(a^{2}\)  

Volume of a cube (side \(a\)) = \(a^{3}\)

Total surface area of a cuboid (length \(l\), breadth \(b\), height \(h\)) = \(2 ( lb + lh + bh)\\\)

Volume of a cuboid (length \(l\), breadth \(b\), height \(h\)) = \(lbh\)

For plating the brick with anything, gold for instance, total surface area of the brick would be calculated to determine the amount of gold needed as all the walls or faces of the brick would be plated but not the interior volume.
