Based on the above, the graph of the resultant vector is shown in the image attached  (x-axis).

We must do a sum of vectors during the graph creation process before drawing the resulting vector.

Thus, while looking at the attached graph, we can claim that the vectors are:

w = <1, 5>

u = <-3, 1>

v = <4, -3>

So, the sum = u - v + w

Note also that in the sum of the vectors we need to add and subtract the correspondent parts and it will be:

u - v + w

= <-3, 1> - <4, -3> + <1, 5>

= <-3 - 4 + 1, 1 + 3 + 5>

= <-6, 9>

Rounding up to the nearest whole number, the quarterback throws 3 passes in the fourth quarter to complete all of them.

Let's first find out how many passes the quarterback completed in the first three quarters:

18 passes completed out of 33 attempts in the first three quarters

= 18/33 = 0.545 (rounded to three decimal places)

We can then find the total number of passes attempted in the first three quarters by using the fact that the completion rate is the number of completions divided by the number of attempts:

0.545 = 18/x, where x is the total number of attempts in the first three quarters

Solving for x, we get:

x = 18/0.545 = 33

So the quarterback attempted 33 passes in the first three quarters.

Next, we can find the total number of passes attempted in the game by using the completion rate for the entire game:

0.625 = (18 + passes completed in the fourth quarter) / (33 + passes attempted in the fourth quarter)

Multiplying both sides by the denominator:

0.625 × (33 + passes attempted in the fourth quarter) = 18 + passes completed in the fourth quarter

20.625 + 0.625 × passes attempted in the fourth quarter = 18 + passes completed in the fourth quarter

Subtracting 18 and 0.625 × passes attempted in the fourth quarter from both sides, we get:

2.625 = passes completed in the fourth quarter - 0.625 × passes attempted in the fourth quarter

Adding 0.625 × passes attempted in the fourth quarter to both sides, we get:

passes completed in the fourth quarter = 2.625 + 0.625 × passes attempted in the fourth quarter

We don't know the exact number of passes attempted in the fourth quarter, but we can see that for every 1 pass attempted, the quarterback completes 0.625 - 0.545 = 0.08 more passes than in the first three quarters. So to complete all of his passes in the fourth quarter, he needs to attempt:

0.08 × x = 0.08 × 33 = 2.64

Question - A quarterback completes 18 of 33 passes during first three quarters of a football game. He completes every pass in the fourth quarter and 62.5% of his passes for the entire game. How many passes does the quarterback throw in fourth quarter?

You just have to include all numbers and make an equation that involves all three digits

The digits missing from the equation are 100, 10 and 1 respectively. The solution has been obtained by using the concept of algebraic equation.

What is algebraic equation?

If a mathematical phrase has variables, constants, and algebraic operations, it is said to be "algebraic" (addition, subtraction, etc.). The expression must contain the equals sign and satisfy the algebraic equation.

We are given an expression as

3. 58 × 100[(3 × 1) + (5 × 0. 1) + (8 × 0. 01)] × 100

On multiplying, we get

When we transform function f, the resulting transformed function may have certain features that are different from the original function.

⇒ g (x) = - f(x-3) is vertical asymptote of x=3

⇒ j (x) = f(x+3) is x-intercept of (-2,0)

⇒ h (x) = 3f(x) - 3 is domain of (0, ∞)

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

Given function is;

⇒ f(x) = log x

Hence, we get;

g(x) = -f(x+3)= - log(x+3)

g(x) =-f(x-3) is vertical asymptote of x = 3.

j (x) = f(x+3) = log (x+3)

Then, j(x) = f(x+3) is x-intercept of (-2,0)

The complete question is shown in figure.

As per the total distance, the distance that Yoni drive on Wednesday is option (c) 5/24 miles.

To find out how far Yoni drove on Wednesday, we must first determine the total distance she drove over the two days.

Tuesday, Yoni drove 1/6 of a mile, which can be expressed as 6/24 of a mile. Wednesday, she drove an additional 9/24 of a mile.

This means that, in total, she drove 15/24 of a mile.

Since we already know that Yoni drove 6/24 of a mile on Tuesday, we can subtract this amount from the total distance she drove over the two days to find out how far she drove on Wednesday.

Subtracting 6/24 of a mile from 15/24 of a mile, we get 9/24 of a mile, which is the distance Yoni drove on Wednesday.

Therefore, Yoni drove 5/24 of a mile on Wednesday

(x + 4)^2 + (y - 3)^2 = 40.

First to complete the square for the given equation:

x^2 + y^2 + 8x - 6y - 15 = 0

We need to group the x and y terms together and add and subtract some constants to make them into perfect squares.

x^2 + 8x + y^2 - 6y = 15

We can add and subtract constants inside the left side of the equation to make it into perfect squares, as follows:

x^2 + 8x + 16 + y^2 - 6y + 9 = 15 + 16 + 9

Now we can rewrite the left side of the equation as a sum of perfect squares:

40 pounds (lb) is equivalent to 18.14 kilograms (kg). To convert pounds to kilograms, you need to use the conversion factor of 0.45359237 kg per pound.

This means that you can multiply the number of pounds by this conversion factor to get the equivalent weight in kilograms.

The conversion from pounds to kilograms is important when it comes to international trade and travel, where weight measurements are typically done in the metric system. Knowing how to convert between different units of measurement is also useful in scientific and engineering fields, where calculations may require using units from different systems.

It's important to note that weight and mass are not the same thing. Weight is a measure of the force exerted on an object by gravity, while mass is a measure of the amount of matter in an object. The conversion from pounds to kilograms assumes that the force of gravity is constant, but this may not always be the case in different parts of the world.

We need to add approximately 14.86 mL of water to 14 mL of 14% alcohol solution to reduce the concentration to 7%.

First, let's figure out how much alcohol is in the first 14 mL of the 14% alcohol solution.

Alcohol is equal to 0.14 x 14 (14%) times 14%, or 1.96 mL.

We need to add water so that the amount of alcohol stays the same while the overall volume grows in order to lower the concentration to 7%.

Assume that x mL of water needs to be added.

The volume of the solution will be (14 + x) mL with the addition of x mL of water, while the amount of alcohol will remain at 1.96 mL.

The equation for the ultimate concentration can be written as follows:

1.96 mL / (14 + x) mL = 0.07

When we find x and simplify, we get:

x = (1.96 mL / 0.07) - 14 mL

x ≈ 14.86mL

In order to lower the concentration to 7%, we must therefore add around 14.86 mL of water to 14 mL of 14% alcohol solution.
