The system of equations that can be used to determine whether the road intersects the boundary of the tower’s signal is

 [tex]y = 2x^2 - 16x + 34\\11y = -5x + 62[/tex]

If a quadratic equation is written in the form

[tex]y=a(x-h)^2 + k[/tex]

then it is called to be in vertex form. It is called so because when you plot this equation's graph, you will see vertex point(peak point) is on (h,k)

For the given situation, the quadratic equation has vertex (h,k) = (4,2) and it passes through (5,4).

If we consider the equation to be of the form [tex]y=a(x-h)^2 + k[/tex],

then, as h = 4, k = 2, it becomes [tex]y = a(x-4)^2 + 2[/tex]

Now since it passes through (5,4), thus at x = 5, and y = 4, the equation must be true, or:

[tex]y = a(x-4)^2 + 2|_{(x,y) = (5,4)}\\\\4 = a(5-4)^2 + 2\\4 = a + 2\\a = 2[/tex]

Thus, the quadratic equation in consideration is: [tex]y = 2(x-4)^2 + 2 = 2x^2 + 32 -16x + 2\\y = 2x^2 - 16x + 34[/tex]

The straight line in consideration connects points (–3, 7) and (8, 2).

Equation of a line passing through two points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex]  is

[tex](y - y_1) = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1)[/tex]

Since we've got [tex](x_1, y_1) = (-3,7) \: \rm and \: \: (x_2, y_2) = (8,2)[/tex]

We get the equation of the straight line in consideration as:

[tex](y - y_1) = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1)\\\\(y-7) = \dfrac{2-7}{8 - (-3) } (x-(-3))\\\\y - 7 = -\dfrac{5}{11}(x+3)\\\\11y = -5x + 62[/tex]

Therefore, the system of equations that can be used to determine whether the road intersects the boundary of the tower’s signal is

[tex]y = 2x^2 - 16x + 34\\11y = -5x + 62[/tex]

These equations' graphs' intersection is the solution to this system

Product of two polynomials can be done by distribution of multiplication over addition. The product of [tex](x+5)^2[/tex] is [tex]x^2 + 10x + 25[/tex]

Suppose a, b and c are three numbers. Then we have:

[tex]a(b + c) = a\times b + a\times c[/tex]

(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)

They are mathematical expressions involving variables raised with non negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non negative exponentiation of variables involved.

Example:

[tex]x^3 + 4x + 3[/tex]

is a polynomial.

Using both above facts, as the given expression is [tex](x+5)^2[/tex]

Its product result is obtained as

[tex](x+5)^2 = (x+5)(x+5) = x(x+5) + 5(x+5) = x^{1+1} + 5x + 5x + 25\\\\(x+5)^2 = x^2 + (5+5)x + 25 \text{\:(Addition of coefficients of like terms)}\\\\(x+5)^2 = x^2 + 10x + 25[/tex]

It is a fact that result of a polynomial product is polynomial. Thus, the obtained product is a polynomial since x + 5 was a polynomial.

Thus,

The product of [tex](x+5)^2[/tex] is [tex]x^2 + 10x + 25[/tex]

Answer:

Step-by-step explanation:

You have more than 1/2 the solution just by knowing the slope.

General equation

y = mx + b         where m is the slope and b is the y intercept.

m = 3/4

Solution

y = 3/4 x + b      Now you need the point to solve for b

x = 2

y = 2                  Substitute these values into the line

2 = 3/4 * 2 + b   Simplify the right

2 = 1 1/2 + b

2 = 3/2 + b        Subtract 3/2 from both sides

2 - 3/2 = b         Combine

1/2 = b

So the y intercept is 1/2

Answer

y = 3/4 x + 1/2

y = 0.75 x + 0.5

The mean number of calls for Sami is 2.25 calls per day and for Marta it is 2.5 calls per day

The person who made more calls per day is Marta.

Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number

Mean = sum of the numbers / total number

Sami = 27 / 12 = 2.25 calls per day

Marta = 45 / 18 = 2.5 calls per day

Probability of an event is its chance of . The probability that a student not liking mountains doesn't like beach is: Option b: 40.4%

Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.

Then, suppose we want to find the probability of an event E.

Then, its probability is given as

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}}[/tex]

Where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.

For the given case, from the table (image attached below), we can see that, there are total 94 students who do not like mountains. Now, out of those 94, there are 38 students not liking beach.

Thus, if A = a student not liking beach

B = not liking mountains,

Then ,

P(A|B) = P(A ∩ B)/P(B) = [tex]\dfrac{38/158}{94/158} = \dfrac{38}{94} \approx 0.404 = 40.4\%[/tex]

Thus, probability of a student not liking beach given that that student doesn't like mountains is 40.4% approx.

========================================================

Explanation:

Check out the diagram below.

The angle of depression being 31 degrees refers to the idea of looking straight horizontal, then looking down 31 degrees. I recommend adding a dashed horizontal line.

That horizontal line is parallel to the ground. This forms a pair of congruent alternate interior angles. Therefore, we have two angles that are 31 degrees as the diagram shows.

The 31 degrees at the bottom is the angle of elevation.

Use this angle of elevation to say...

tan(angle) = opposite/adjacent

tan(31) = x/12

x = 12*tan(31)

x = 7.210327 approximately

This rounds to 7.2 feet

Answer:

B- n = 1

Step-by-step explanation:

"For all the positive integers n" is a qualifying statement. The number used has to be positive and also must be an integer. Integers are whole numbers and their opposites, so basically no fractions and no decimals. Answer A is a fraction and C is a decimal and D is negative and a decimal. So they don't work for this problem.

The value is n to show that the first step in a proof by mathematical induction of for all the positive integers is 1.

Thus, option B is correct.

The conditions can be checked through the options.

The option C and D will be eliminated because the condition is for all the positive integers n but n is decimal here.

For n = 1/4, the solution will be in fractions.

So, it does not hold true for n= 1/4.

For n = 1

[tex]\dfrac{n(n + 1)(2n + 1)}{6}[/tex]

 =[tex]\dfrac{1(1 + 1)(2 \times 1 + 1)}{6}[/tex]

= 1

Thus, the value is n  to show that the first step in a proof by mathematical induction of for all the positive integers n is 1.

So, option B is correct.
