The sales price of the item after the 15% discount is $850.

The original price of the item is $1,000 and the discount rate is 15%. To find the amount of the sales price, we need to calculate the amount of the discount and subtract it from the original price.

Step 1: Calculate the amount of the discount by multiplying the original price by the discount rate.
Discount = Original Price x Discount Rate
Discount = $1,000 x 0.15
Discount = $150

Step 2: Subtract the amount of the discount from the original price to find the sales price.
Sales Price = Original Price - Discount
Sales Price = $1,000 - $150
Sales Price = $850

Therefore, the sales price of the item after the 15% discount is $850.

The equation for the line that passes through the point (-1,4) and that is parallel to the line with the equation y=2 is y=4.

To find the equation for the line that passes through the point (-1,4) and that is parallel to the line with the equation y=2, we need to use the concept of slope. The slope of a line is the ratio of the vertical change to the horizontal change between any two points on the line.

The equation y=2 is a horizontal line, which means that its slope is 0. Since the line we are looking for is parallel to this line, its slope will also be 0.

Now that we know the slope, we can use the point-slope form of an equation to find the equation of the line. The point-slope form of an equation is [tex]y-y1=m(x-x1)[/tex], where m is the slope and [tex](x1,y1)[/tex] is a point on the line.

Plugging in the values we know, we get:

[tex]y-4=0(x-(-1))[/tex]

Simplifying the equation, we get:

[tex]y-4=0[/tex]

Adding 4 to both sides of the equation, we get:

[tex]y=4[/tex]

Therefore , the solution of the given problem of function comes out to be Nolan dropped the ball from a height of 12 units at the beginning.

The study of mathematics includes numbers, symbols, and their parts, as well as anatomy, building, and both actual and hypothetical geographic locations. The relationships between different components, each of which has a corresponding result, are described by a function. A function is made up of a variable of distinct components that, when put together, produce specific results for each input.

Here,

Assume that h represents the original height at which Nolan threw the ball. The object bounces once and rises to a height of 4, so after the bounce it has a height of h + 4.

=> h = k f(1) (1)

where k is a constant that denotes how much energy the object retains after each bounce.

=> h = k(4) (4)

The knowledge that the ball returns to a height of 4 on the first bounce must be used to determine the value of k:

=> 4 = k f(1) (1)

=> 4 = k (4/3)

=> k = 3

When we put this number of k back into the equation as a replacement for h, we get:

=> h = k(4) = 3(4) = 12

Nolan dropped the ball from a height of 12 units at the beginning.

The intersection point of ℓ and Q is (1, 1, 2.5) is not in any of the option.

To find the intersection point of ℓ and Q, we need to find a point that lies on both the line and the plane. We can do this by finding the equation of the line and the equation of the plane, and then solving for the point where they intersect.

First, let's find the equation of the line ℓ. We can use the formula for a line passing through two points:

(x - x1) / (x2 - x1) = (y - y1) / (y2 - y1) = (z - z1) / (z2 - z1)

Plugging in the points (1, 1, 1) and (2, 0, 1), we get:

(x - 1) / (2 - 1) = (y - 1) / (0 - 1) = (z - 1) / (1 - 1)

Simplifying, we get:

x - 1 = -y + 1 = 0

So the equation of the line is x + y = 2.

Next, let's find the equation of the plane Q. We can use the formula for a plane passing through three points:

| x - x1  y - y1  z - z1 |
| x2 - x1  y2 - y1  z2 - z1 | = 0
| x3 - x1  y3 - y1  z3 - z1 |

Plugging in the points (0, 0, 0), (1, 2, 2), and (1, 0, 1), we get:

| x   y   z |
| 1   2   2 | = 0
| 1   0   1 |

Expanding the determinant, we get:

x(2 - 0) - y(2 - 1) + z(0 - 2) = 0

Simplifying, we get:

2x - y - 2z = 0

So the equation of the plane is 2x - y - 2z = 0.

Now we can solve for the intersection point of the line and the plane by substituting the equation of the line into the equation of the plane:

2(x + y) - y - 2z = 0

2x + 2y - y - 2z = 0

2x + y - 2z = 0

Since x + y = 2, we can substitute 2 for x + y:

2(2) + y - 2z = 0

4 + y - 2z = 0

y - 2z = -4

Now we can solve for y in terms of z:

y = 2z - 4

And substitute this back into the equation of the line:

x + (2z - 4) = 2

x = 2 - 2z + 4

x = 6 - 2z

Now we have two equations with two unknowns:

y = 2z - 4
x = 6 - 2z

We can solve for z by setting the two equations equal to each other:

2z - 4 = 6 - 2z

4z = 10

z = 2.5

And then solve for x and y:

y = 2(2.5) - 4 = 1
x = 6 - 2(2.5) = 1

So the intersection point of ℓ and Q is (1, 1, 2.5).

For 175÷2, the quotient is 87 and remainder is 1

When dividing 175 by 2, we can use long division to find the quotient and remainder.

First, we will divide 2 into the first digit, 1. Since 2 does not go into 1, we will move to the next digit, 7. 2 goes into 7 three times, so we will write 3 above the 7.

Next, we will multiply 3 by 2 to get 6, and subtract this from 7 to get a remainder of 1.

We will then bring down the next digit, 5, and divide 2 into 15. 2 goes into 15 seven times, so we will write 7 above the 5.

Finally, we will multiply 7 by 2 to get 14, and subtract this from 15 to get a remainder of 1.

Therefore, the quotient is 87 and the remainder is 1.

Molarity is a measure of the concentration of a solution expressed in the number of moles dissolved per liter of solution.

This is, the molarity indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

molarity= number of moles of solute÷ volume

Molarity is expressed in units moles/L.

The molar mass of substance is a property defined as the amount of mass that a substance contains in one mole.

In this case, you have:

Replacing in the definition of molarity:

0.350 M= number of moles of solute÷ 0.215 L

Solving:

0.350 M× 0.215 L= number of moles of solute

0.07525 moles= number of moles of solute

Being the molar mass of MgBr₂ 184.11 g/mole, the mass of the compound is calculated as:

mass of MgBr₂= 0.07525 moles× 184.11 g/mole

mass of MgBr₂= 13.85 grams

The plane will end up flying 1.7 degrees off course.
The plane's speed relative to the ground will be 729.1 km/hr.

To determine the plane's speed and direction relative to the ground, we need to use vector addition to combine the velocity of the plane and the velocity of the wind.

First, let's find the components of the wind velocity. Since the wind is blowing from the southeast, its x-component is -30cos(45) = -21.2 km/hr and its y-component is -30sin(45) = -21.2 km/hr.

Next, let's find the components of the plane's velocity. Since the plane is heading north, its x-component is 0 km/hr and its y-component is 750 km/hr.

Now, we can add the components of the plane's velocity and the wind's velocity to find the plane's velocity relative to the ground:

x-component: 0 + (-21.2) = -21.2 km/hr

y-component: 750 + (-21.2) = 728.8 km/hr

Finally, we can use the Pythagorean theorem to find the magnitude of the plane's velocity relative to the ground:

speed = sqrt((-21.2)^2 + (728.8)^2) = 729.1 km/hr

And we can use the inverse tangent function to find the direction of the plane's velocity relative to the ground:

direction = tan^(-1)(-21.2/728.8) = -1.7 degrees

So, the plane will end up flying 1.7 degrees west of north, and its speed relative to the ground will be 729.1 km/hr.
