Answer:

The measure of angle EYH is [tex]25\°[/tex]

Step-by-step explanation:

step 1

Find the measure of arc EH

we know that

[tex]arc\ EV+arc\ VL+arc\ HL+arc\ EH=360\°[/tex] ----> by complete circle

substitute the given values

[tex]130\°+110\°+40\°+arc\ EH=360\°[/tex]

[tex]280\°+arc\ EH=360\°[/tex]

[tex]arc\ EH=360\°-280\°=80\°[/tex]

step 2

Find the measure of angle EYH

we know that

The measurement of the outer angle is the semi-difference of the arcs which comprises

[tex]m<EYH=\frac{1}{2}(arc\ EV-arc\ EH)[/tex]

substitute the values

[tex]m<EYH=\frac{1}{2}(130\°-80\°)=25\°[/tex]

Answer:

Option B

Step-by-step explanation:

We know that a parabola is a set of points that are equidistant from a given line, which is the directrix, and a given fixed point called the focus.

So the correct option is option B.

Answer: Option 'B' is correct.

Step-by-step explanation:

Parabola is a curve in which any given point is at equal distance from focus i.e. a fixed point and directrix i.e. a fixed line.

So, it is the set of all points forming  the curve that is equidistant from a single point and a single line.

Hence , option 'B' is correct.

Answer:

98

Step-by-step explanation:

If half the diagonal is 7 yd, then the full diagonal is 14 yd.

If we call the side length s, then using Pythagorean theorem:

c² = a² + b²

(14)² = s² + s²

196 = 2s²

s² = 98

The area of a square is s², so:

A = s²

A = 98

The area is 98 yd².

You can factor -80 as

[tex]-80 = (-1)\cdot 16 \cdot 5[/tex]

So, we have

[tex]\sqrt{-80} = \sqrt{(-1)\cdot 16 \cdot 5}[/tex]

The square root of a product is the product of the square roots:

[tex]\sqrt{-80} = \sqrt{(-1)}\sqrt{16}\sqrt{5}[/tex]

Since [tex]i^2=-1[/tex] and [tex]4^2=16[/tex], we have

[tex]\sqrt{-80} = 4i\sqrt{5}[/tex]

The equivalent expression of the complex expression √(-80) will be 4i√5. Then the correct option is C.

A complex number is a number that is made up of both real and imaginary numbers. The complex number can be given as a + ib where a is the real part and ib is the imaginary part.

The expression is given below.

⇒ √(-80)

And we know that √(-1) = i

Then the expression can be written as

⇒ √(-1 x 16 x 5)

⇒ 4i√5

Last option

[tex]y = 3cos(\pi(x+2)) + 5[/tex]

Step-by-step explanation:

The general cosine function has the following form  

[tex]y = Acos(b(x-\phi)) + k[/tex]

Where A is the amplitude: half the vertical distance between the highest peak and the lowest peak of the wave.  

[tex]\frac{2\pi}{b}[/tex] is the period: time it takes the wave to complete a cycle.

k is the vertical displacement.

[tex]\phi[/tex] is the shift phase

In this problem :

[tex]A = 3[/tex]

[tex]\frac{2\pi}{b}=2\\\\ b=\frac{2\pi}{2}\\\\ b=\pi[/tex]

[tex]\phi =-2\\\\k = 5[/tex]

So  The function is:

[tex]y = 3cos(\pi(x+2)) + 5[/tex]

A = person is under 20

B = person is over 60

P(A or B) = P(A) + P(B) ... works because A and B are mutually exclusive

P(A or B) = 0.30 + 0.17

P(A or B) = 0.47 = 47%

The probability that a person chosen at random is under 20 or over 60 is 47% , option C is the correct answer.

Probability is a topic in mathematics  where the likeliness of an event is studied.

The range of probability is 0 to 1 .

0 indicates uncertainty to 1 indicating certainty.

It is given in the question that

30% of the U.S. population is under 20 years old

About 17% of the population is over 60

probability that a person chosen at random is under 20 or over 60 = ?

Let P(A) represents person under 20

Let P(B) represents person over 60

As a person is chosen at random and the events cannot happen together so they are mutually exclusive events.

The probability for mutually exclusive event is given by

P(A or B) = P(A) + P(B)

P(A) = 17% = 0.17

P(B) = 30% = 0.3

P(A or B) = 0.30 + 0.17

P(A or B) = 0.47 = 47%

Therefore , the probability that a person chosen at random is under 20 or over 60 is 47% , option C is the correct answer.

Answer:

Answer: x = 32, y = 25

Step-by-step explanation:

You can write 2 equations that meet the criteria:

The sum of two numbers is 57

x + y = 57

The difference is 7

x - y = 7

Solve the second equation for x, and substitute in the first equation to solve for y

- solve the second equation for x.  

Add y to both sides of the equation

x - y + y = 7 + y

x = 7 + y

- substitute x = 7 + y into the first equation

x + y = 57

(7 + y) + y = 57

7 + 2y = 57

Subtract 7 from both sides of the equation

7 - 7 + 2y = 57 - 7

2y = 50

Divide both sides of the equation by 2 to solve for y

y=25

Insert y = 25 into either equation and solve for x

x - y = 7

x - 25 = 7

Add 25 to both sides of the equation

x - 25 + 25 = 7 + 25

x = 32

Answer: x = 32, y = 25

As a check, plug these values into both equations to make sure that it works

Answer:

C. [tex]f(x)=(x-(7-i))(x-(5+i))(x-(7+i))(x-(5-i))[/tex]

Step-by-step explanation:

We want to find the equation of a polynomial the following properties;

i. Leading coefficient is 1

ii. roots (7 + i) and (5 – i) with multiplicity 1

Recall the complex conjugate properties of the roots of a polynomial.

According to this property, if

[tex]a+bi[/tex] is a root of a polynomial, then the complex conjugate, [tex]a-bi[/tex]  is also a root.

This means that:

(7 - i) and (5 + i) with multiplicity 1 are also roots of this polynomial.

The complete set of roots are:

[tex]x=(7+i),x=(7-i),x=(5-i),x=(5+i)[/tex]

Therefore the polynomial is:

[tex]f(x)=(x-(7-i))(x-(5+i))(x-(7+i))(x-(5-i))[/tex]

The correct choice is C.

Final answer:

The correct polynomial function with roots (7 + i) and (5 – i), each with multiplicity 1 and a leading coefficient of 1, is given by (c) f(x) = (x – (7 + i))(x – (5 – i))(x – (7 - i))(x – (5 + i)).

Explanation:

The question asks which polynomial function has a leading coefficient of 1 and roots (7 + i) and (5 – i) with multiplicity 1. For a polynomial to have these roots, its conjugates, (7 - i) and (5 + i), must also be roots because complex roots always come in conjugate pairs if the polynomial has real coefficients.

This leads us to option (c) as the correct answer. To form a polynomial with these roots, we take each root, turn it into a binomial by subtracting it from x, and then multiply these binomials together.

Doing so for the given roots, we get:

f(x) = (x – (7 + i))(x – (5 – i))(x – (7 - i))(x – (5 + i))

This polynomial matches option (c), confirming it as the correct answer.

Answer:

3, 7

Step-by-step explanation:

Since we are asked for the known solutions to f(x) = g(x), we need to consider the values of the functions where x's are the same.

If you look at the table, you will see that f(-9) = g(-9) = 3 and f(2) = g(2) = 7.

The value of x where f(x) = g(x) is 3

According to the given question, we are to find the value of x for which the function f(x) is equal to g(x)

From the given table, we need to find the point where the values of f(x) = g(x). The value of x at this point is the solution.

Therefore from the table, the value of x where f(x) = g(x) is 3

Step-by-step explanation:

The lateral area of a triangular prism is:

[tex]A_L = Ph[/tex]

Where P is the perimeter of the triangular base and h is the height of the prism.

In this case, the perimeter of the triangular base is:

[tex]P = 9 + 6+ 10.82\\\\P = 25.82\ m[/tex]

Then the height is 26 m

Then the lateral area of the prism is:

[tex]A_L = 25.82 * (26)\\\\A_L = 671\ m ^ 2[/tex]

Therefore the surface area of the triangular prism is:

[tex]A = 2A_B + A_L[/tex]

Where [tex]A_B[/tex] is the area of the base.

[tex]A_B = \frac{bh}{2}[/tex]

Where b is the base of the triangle and h is the height

In this case:

[tex]b = 9\ m\\\\h = 6\ m\\\\A_B = \frac{9 * 6}{2}\\\\A_B = 27\ m ^ 2[/tex]
