Answer:

A = (x^2 - 2x - 8) m^2

Second option

Step-by-step explanation:

Area of rhombus = 1/2 d1 * d2

= 1/2(2x+4)(x-4)

= 1/2 (2x^2 -8x + 4x - 16)

= 1/2 (2x^2 - 4x - 16)

= x^2 - 2x - 8

As given,

Number of sheets of paper put in the binder 8 days ago = 50 sheets

Current number of sheets left after 8 days = 2 sheets

So, number of sheets used in 8 days = [tex]50-2=48[/tex] sheets

As it is stated that the same number of sheets are used each day, so number of sheets used per day = [tex]\frac{48}{8}=6[/tex] sheets.

Hence, 6 sheets of paper were used each day.

a = 4^-0 = 1

b = 4^-2 = 1/16

c = 4^-4 = 1/256

d = (2/3)^0 = 1

e = (2/3)^2 = 4/9

f = (2/3)^4 = 16/81

The value of a, b, c, d, e, and f are 1, 1/16, 1/256, 1, 4/9, and 16/81 after plugging the values of x.

It is defined as the function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a×

where a is a constant and a>1

We have:

y = 4⁻ˣ

x = 0

a = 4⁻⁰ = 1

x = 2

b = 4⁻² = 1/16

x = 4

c = 4⁻⁴ = 1/256

y = (2/3)ˣ

x = 0

d = (2/3)⁰ = 1

x = 2

e = (2/3)² = 4/9

x = 4

f = (2/3)⁴ = 16/81

Thus, the value of a, b, c, d, e, and f are 1, 1/16, 1/256, 1, 4/9, and 16/81 after plugging the values of x.

The total cost price of the car is $2,345.2.

Given that, a car insurance company paid 1758.90 to repair a car that has been rear-ended. This was 75% of the total cost of the repair.

We need to find what was the total cost price of the car.

The amount paid to purchase an article or the price at which an article is made is known as its cost price. The cost price is abbreviated as C.P. Selling Price: The price at which an article is sold is known as its selling price. The selling price is abbreviated as S.P.

Let the total cost price be x.

Now, 75% of x=1758.90

⇒0.75×x=1758.90

⇒x=$2,345.2

Therefore, the total cost price of the car is $2,345.2.

Whe have:

[tex]2a^2 + 2b^2 - 5ab[/tex]

Then:

[tex]n = 2\\\\m = -5b\\\\c = 2b^2[/tex]

The quadratic formula is:

[tex]a =\frac{-m\±\sqrt{m^2-4nc}}{2n}[/tex]

Then the solutions are:

[tex]a= \frac{-(-5b)\±\sqrt{(-5b)^2 -4(2)(2b^2)}}{2(2)}\\\\a = \frac{5b\±\sqrt{25b^2-16b^2}}{4}\\\\a = \frac{5b\±3b}{4}\\\\a_1=2b\\\\a_2 =\frac{b}{2}[/tex]

Finally The factored expression is:

[tex] R = 10.39^\circ [/tex]

Step-by-step explanation:

Since you have the lengths of all the sides, you can use sine, cosine, or tangent to find the answer. Let's use the tangent ratio.

For angle C, AB is the opposite leg, and BC is the adjacent leg.

[tex] \tan C = \dfrac{opp}{adj} [/tex]

[tex] \tan C = \dfrac{22}{120} [/tex]

[tex] C = \tan^{-1} \dfrac{22}{120} [/tex]

[tex] C = 10.39^\circ [/tex]

Applying the tangent ratio (tan ∅ = opposite length/adjacent length), the measure of angle C, to the nearest hundreth, is: 10.39°

In a given right triangle, the tangent ratio is given as, tan ∅ = opposite length/adjacent length.

Given the following:

Answer:

163/500 = 0.326

Step-by-step Explanation:

Drawing a Venn diagram for this, we will have 3 circles.  One will represent rock, one will represent country, and one will represent jazz.

There are 11 students that like all 3 types of music.  This means the number 11 goes in the intersection of all 3 circles.

There are a total of 30 students that like rock and country; taking out the 11 that like all 3, this leaves 30-11 = 19 students in the intersection of just rock and country.

There are a total of 27 students that like rock and jazz; taking out the 11 that like all 3, this leaves 27-11 = 16 students in the intersection of just rock and jazz.

There are a total of 22 students that like country and jazz; taking out the 11 that like all 3, this leaves 22-11 = 11 students in the intersection of just country and jazz.

There are 206 students that like rock; taking out the 11 that like all 3, the 19 that like rock and country, and the 16 that like rock and jazz, we have

206-(11+19+16) = 206-(46) = 160 in just rock.

There are 161 students that like country; taking out the 11 that like all 3, the 19 that like rock and country, and the 11 that like country and jazz, we have

161-(11+19+11) = 161-(41) = 120 in just country.

There are 118 students that like jazz; taking out the 11 that like all 3, the 16 that like rock and jazz, and the 11 that like country and jazz, we have

118-(11+16+11) = 118-38 = 80 in just jazz.

This leaves

500-(80+120+160+11+11+19+16) = 500-417 = 83 students that like none of the 3 types of music.

This means for the probability that a student likes neither rock nor country, they either like just jazz or none of the 3; this is (83+80)/500 = 163/500 = 0.326.

The probability that a randomly selected student likes neither rock nor country is;

P(R' ∩ C') = 0.326

Let us denote them as follows;

Number that like rock music be R

Number that like Country music be C

Number that like Jazz music be J

Thus, as we are given we have;

R = 206

C = 161

J = 118

R ∩ C = 30 - 11 = 19

R ∩ J = 27 - 11 = 16

C ∩ J = 22 - 11 = 11

R ∩ C ∩ J = 11

n(only jazz) = J - [(R ∩ J) + (C ∩ J) + (R ∩ C ∩ J)]

n(only jazz) = 118 - (16 + 11 + 11)

n(only J) = 80

n(only Rock) = R - [(R ∩ C) + (R ∩ J) + (R ∩ C ∩ J)]

n(only Rock) = 206 - (19 + 16 + 11)

n(only R) = 160

n(only country) = C - [(R ∩ C) + (C ∩ J) + (R ∩ C ∩ J)]

n(only country) = 161 - (19 + 11 + 11)

n(only C) = 120

Now, the number of students that like neither of the 3 music is;

A' ∩ B' ∩ C' =  500 - [(R ∩ C) + (R ∩ J) +  (C ∩ J) + (R ∩ C ∩ J) + n(only J) + n(only R) + n(only C)]

⇒ 500 - (80 + 120 + 160 + 19 + 16 + 11 + 11)

⇒ A' ∩ B' ∩ C' = 83

Thus, number of students that likes neither rock nor country is;

n(A' ∩ B') = (A' ∩ B' ∩ C') + n(only C)

n(A' ∩ B') = 83 + 80

n(A' ∩ B') = 163

Thus, probability that a randomly selected student likes neither rock nor country = 163/500 = 0.326

Answer:

Equation 3

Step-by-step explanation:

An identity is, simply put, an equation that is always true. 1 = 1, 2 = 2, and x = x are all examples of identities, as there's no case in which 1 ≠ 1, 2 ≠ 2, and x ≠ x. Essentially, if we can manipulate and equation so that we end up with the same value on either side, we've found an identity. Let's run through and try to solve each of these equations to see which one fulfills that condition:

8 - (6v + 7) = -6v - 1

8 - 6v - 7 = -6v - 1

1 - 6v = -6v - 1

1 = -1

This is clearly untrue. Moving on to the next equation:

5y + 5 = 5y - 6

5 = -6

Untrue again. Solving the third:

3w + 8 - w = 4w - 2(w - 4)

2w + 8 = 4w - 2w + 8

2w + 8 = 2w + 8

If we created a new variable z = 2w + 8, we could rewrite this equation as

z = z, which is always true. We can stop here, as we've now found that equation 3 is an identity.

The identity among the given equations is 3w + 8 - w = 4w - 2(w - 4), as it simplifies to a true statement 2w + 8 = 2w + 8 for all values of w.

The student asked which equation is an identity. To find the identity, we simplify and solve each equation:

8 – (6v + 7) = –6v – 1: When we simplify, we get 8 - 6v - 7 = -6v - 1, which further simplifies to 1 - 6v = -6v - 1. Adding 6v to both sides, we have 1 = -1, which is not true, so it's not an identity.

5y + 5 = 5y – 6: Simplifying this we simply subtract 5y from both sides, and we are left with 5 = -6, which is not true, so this is not an identity either.

3w + 8 – w = 4w – 2(w – 4): Simplifying we get 2w + 8 = 4w - 2w + 8, which reduces to 2w + 8 = 2w + 8. This is true for all values of w, therefore, this is an identity.

6m – 6 = 7m + 9 – m: Simplifying gives us 6m - 6 = 6m + 9. Subtracting 6m from both sides, we get -6 = 9, which is not true and thus not an identity.

The identity is the equation 3w + 8 – w = 4w – 2(w – 4) because it simplifies to a true statement regardless of the value of w.

Answer: 10,472.36 feet

Step-by-step explanation:

- Observe the diagram attached (It is not drawn to scale).

- Calculate the height between helicopter and airplane (h), as following:

[tex]tan\alpha=\frac{opposite}{adjacent}\\\\tan(71\°)=\frac{h}{3,055}[/tex]

Solve for h:

[tex]h=(3,055)(tan(71\°))\\h=8,872.36ft[/tex]

- Therefore, the altitude of the plane is:

[tex]altitude=1,600ft+8,872.36ft\\altitude=10,472.36ft[/tex]

You can use the tangent ratio to find the airplane's altitude.

The altitude of the airplane in the given condition is 10,471.72 ft

You look straight parallel to ground. But when you have to watch something high, then you take your sight up by moving your head up. The angle from horizontal to the point where you stopped your head is called angle of elevation.

In a right angled triangle(triangle with one of the angles as right angle which is 90 degrees), seeing from perspective of an angle, the tangent ratio is the ratio of the side opposite to that angle and the side which is perpendicular to that opposite side.

Refer to the attached figure.
The altitude of the plane is the length of the line segment CE.

We have the rectangle ABDE, thus, AD = BE in terms of length.

(remember that |AB| means length of line segment AB).

Thus,
|CE| = |CB| + |BE| = |CB| + 1600 ft

Using the tangent ratio for triangle ABC from angle A, we get:

[tex]tan(A) = \dfrac{|CB|}{|AB|} = \dfrac{|CB|}{3055}\\\\tan(71) \approx 2.904 = \dfrac{|CB|}{3055}\\\\|CB| = 3055 \times 2.904 = 8.871.72 \: \rm ft[/tex]

Thus,

|CE| = |CB| + 1600  = 8871.72 + 1600 = 10,471.72 ft.

Thus,

The altitude of the airplane in the given condition is 10,471.72 ft

In this problem we have

[tex]A=53\frac{5}{8}\ ft^{2}[/tex]

[tex]W=6\frac{1}{2}\ ft[/tex]

convert to an improper fraction

[tex]A=53\frac{5}{8}=\frac{53*8+5}{8}=\frac{429}{8}\ ft^{2}[/tex]

[tex]W=6\frac{1}{2}=\frac{6*2+1}{2}=\frac{13}{2}\ ft[/tex]

substitute in the formula and solve for L

[tex]\frac{429}{8}=L\frac{13}{2}[/tex]

[tex]L=\frac{429*2}{8*13}=\frac{858}{104}\ ft[/tex]

Convert to mixed number

[tex]L=\frac{858}{104}=\frac{832}{104}+\frac{26}{104}=8\frac{1}{4}\ ft[/tex]

The length of the bathroom floor in this case is 8 1/4 feet.

The area of a rectangle is calculated by multiplying its length by its width. In this case, with the bathroom floor having an area of 53 5/8 square feet and a width of 6 1/2 feet, we can find the length as follows:

Area = Length x Width

53 5/8 = Length x 6 1/2

Length = 53 5/8 / 6 1/2

Length = 8 1/4 feet

Therefore, the length of the bathroom floor is 8 1/4 feet.
