Which Of The Following Statements Are True Of The Parabola Shown?1. It Has A Directrix Of X = -4.2. It

Answers

Answer 1

True statements are:

It has a directrix of x = - 4.It has a focus at (4, 0).

Step-by-step explanation:

We have the following statements to check on whether it's right or wrong:

1. It has a directrix of x = -4:

According to figure , parabola directrix is at -4 i.e. at x = -4 , Therefore this statement is true!

2. It opens to the left:

In figure, Parabola opens to right not left , Therefore this statement is wrong!

3. It has a vertex at the origin:

Vertex of Parabola is at what points not shown in figure. Therefore this statement cannot be confirmed as true.

4. The axis of symmetry is the y-axis:

Axis of symmetry for above parabola is x-axis as it cuts parabola into two equal halves , y-axis doesn't do this ! Therefore this statement is wrong!

5. It has a focus at (4, 0):

Parabola focus is at [tex]F(4,0)[/tex] on x-axis . And so, Therefore this statement is true!

Answer 2

1. True it has a directrix of x = -4; 2. False it opens to the left; 3. False it has a vertex at the origin; 4. True the axis of symmetry is the y-axis; 5. True it has a focus at (4, 0).

In this parabola, the given statements can be evaluated as follows:

1. Directrix : The given directrix is x = -4. The directrix of a parabola is a vertical line that is equidistant from all points on the parabola. In this case, the directrix is to the left of the origin, so it's possible that the parabola opens to the right.

2. Direction of Opening : The parabola cannot open to the left because the given directrix is to the left of the origin. Parabolas open towards their focus or away from their directrix. Since the directrix is to the left, the parabola opens to the right.

3. Vertex : The vertex is the point where the parabola changes direction. The origin (0, 0) is not the vertex in this case, as the parabola opens to the right.

4. Axis of Symmetry: The axis of symmetry is a vertical line that passes through the vertex and divides the parabola into two equal halves. Since the parabola opens to the right, its axis of symmetry is the y-axis.

5. Focus : The focus is a point inside the parabola that is equidistant to the vertex and the directrix. The focus should indeed be to the right of the vertex, and at a distance of 4 units, based on the given directrix

x = -4.

Mathematically, the equation of a parabola that opens to the right, with its vertex at the origin, is of the form:

[tex]\[x^2 = 4py\][/tex]

Given that the directrix is x = -4, the distance from the origin to the directrix is 4 units. So, the equation becomes:

[tex]\[x^2 = 16y\][/tex]

The focus is at a distance of p units from the vertex, where [tex]\(p = 4\)[/tex], so the focus is at (4, 0).

In summary, the given parabola opens to the right, has a vertex at the origin, its axis of symmetry is the y-axis, and its focus is at (4, 0), with a directrix of x = -4.

The value of [tex]\log _{6}(36)[/tex] is 2.

Solution:

Given expression is [tex]\log _{6}(36)[/tex].

To evaluate the expression:

[tex]\log _{6}(36)[/tex]

36 can be written as 6².

       [tex]=\log _{6}\left(6^{2}\right)[/tex]

Using log rule: [tex]\log _{a}\left(x^{b}\right)=b \cdot \log _{a}(x)[/tex]

       [tex]=2 \log _{6}(6)[/tex]

Using log rule: [tex]\log _{a}(a)=1[/tex] so that [tex]\log _{6}(6)=1[/tex]

       = 2(1)

       = 2

[tex]\log _{6}(36)=2[/tex]

Hence the value of [tex]\log _{6}(36)[/tex] is 2.

Final answer:

To find log₆ 36, we determine the exponent that 6 must be raised to to get 36. As 6 squared equals 36, the value of log base 6 of 36 is 2.

Explanation:

The question asks us to evaluate the logarithm of 36 with a base of 6, or, in mathematical terms, log base 6 of 36. We can solve this by recalling the definition of a logarithm, which is the power to which a base number must be raised to yield a given number. Since 6 squared is equal to 36 (6² = 36), the logarithm of 36 with a base of 6 is equal to 2.

y = 75

Solution:

In a straight line, sum of the adjacent angles = 180°

80° + m∠DGF = 180°

Subtract 80° from both sides of the equation.

m∠DGF = 100°

Sum of all the interior angles in a quadrilateral = 360°

m∠DGF + m∠GFE + m∠FED + m∠EDG = 360°

100° + 120° + 65° + y° = 360°

285° + y° = 360°

Subtract 285° from both sides, we get

y° = 75°

Hence the value of y is 75.

Sigi’s taxi company charges $0.60 per mile and adds an additional $4.50 to cover the cost of bridge tolls. The expression below represents this relationship.

0.60m + 4.50

How much will the taxi company charge for a 36-mile drive?

a) $5.10
b) $26.10
c) $27.00
d) $41.10

Answers

B because you have to multiply .60 and 36 than add 4.50

Final answer:

To calculate the charge for a 36-mile drive by Sigi's taxi company, multiply 0.60 by 36 to find the mileage cost, add the $4.50 bridge toll, which results in a total cost of $26.10. Hence, the correct answer is (b) $26.10.

Explanation:

The question asks how much Sigi’s taxi company will charge for a 36-mile drive considering their rate is $0.60 per mile and there is an additional charge of $4.50 for bridge tolls. To calculate the total cost, you can use the given expression 0.60m + 4.50, where 'm' represents the number of miles.

By substituting 36 for 'm', you get the following calculation: 0.60 × 36 + 4.50. The cost per mile for 36 miles amounts to $21.60 ($0.60 times 36). Add the additional $4.50 charge for bridge tolls to get a total charge of $26.10.

Step-by-Step Calculation:

Calculate the cost of the mileage: 0.60 × 36 = $21.60.Add the fixed bridge toll cost: $21.60 + $4.50 = $26.10.

Answers

Answer:

The total area of the field is 7378.8 square meters.

The total area of the field is 8825.0448 square yards.

Step-by-step explanation:

Given : A soccer field (football pitch) has a length of 103.2 m and a width of 71.5 m.

To find : The total area of the field in square meters (m²) and convert this measurement to square yards (yd²) ?

Solution :

The length l=103.2 m

The width w=71.5 m

The area of the field is [tex]A=l\times w[/tex]

[tex]A=103.2\times 71.5[/tex]

[tex]A=7378.8\ m^2[/tex]

The total area of the field is 7378.8 square meters.

We know that,

1 m²= 1.196 yd²

[tex]7378.8\ m^2=7378.8\times 1.196\ yd^2[/tex]

[tex]7378.8\ m^2=8825.0448\ yd^2[/tex]

The total area of the field is 8825.0448 square yards.

Final answer:

The area of the soccer field is 7378.8 m^2 and 8822.6 square yards.

Explanation:

The area of a rectangle (which is the shape of a soccer field) can be found by multiplying the length and the width. So, the area of the soccer field in square meters is 103.2 m (length) times 71.5 m (width), which equals 7378.8 m2.

To convert this area to square yards, you should know that 1 square meter is approximately equal to 1.19599 square yards. So, multiply our previous answer with this value. The area of the soccer field will be 7378.8 m2 times 1.19599 to get 8822.6 yd2.

Answers

Answer:

Approximately 252 inches squared.

Step-by-step explanation:

Answer:

126 in.^2

Step-by-step explanation:

The hexagon is divided into 6 congruent triangles. The area of the hexagon is 6 times the area of one of the triangles.

Now think of each triangle.

The side of the hexagon is the base of the triangle. The side of the hexagon has length 7 inches, so the base of the triangle has length 7 inches.

The height of the triangle is approximately 6 inches.

area of triangle = base * height/2

area of hexagon = 6 * area of triangle

area of hexagon = 6 * base * height/2

area of hexagon = 3 * base * height

area of hexagon = 3 * 7 in. * 6 in.

area of hexagon = 126 in.^2

A triangular banner has a base length of 48
inches. The banner has an area of 1,632 square
inches. What is the height of the banner?​

Answers

Answer:68

Step-by-step explanation:

Area of triangle=1/2×base×height

1632=1/2×48×h

1632×2=48×h

3264=48×h

3264/48=h

68=h

Final answer:

To find the height of a triangle with an area of 1,632 square inches and a base of 48 inches, we use the formula A = (base × height) / 2. Solving for height gives us a result of 68 inches.

Explanation:

To calculate the height of a triangle when its area and base length are known, we use the formula for the area of a triangle: A = (base × height) / 2. Given that the area of the triangular banner is 1,632 square inches and the base length is 48 inches, we can set up the equation:

1,632 = (48 × height) / 2

Multiplying both sides of the equation by 2 to get rid of the denominator:

3,264 = 48 × height

Next, divide both sides by 48 to isolate the height:

height = 3,264 / 48

height = 68 inches

Therefore, the height of the triangular banner is 68 inches.

The supplement of an angle is six times as large as the complement of the angle. What is the measure of the angle to the nearest whole degree?

Answers

The measure of the angle to the nearest whole degree is 72 degrees

Solution:

Complementary angles add up to 90° and supplementary angles add up to 180°

Let "a" be the required angle

Supplement of an angle = 180 - a

Complement of angle = 90 - a

The supplement of an angle is six times as large as the complement of the angle.

Therefore,

180 - a = 6(90 - a)

Simplify the above

180 - a = 540 - 6a

6a - a = 540 - 180

Combine the like terms

5a = 360

Divide both sides by 5

a = 72

Thus the measure of the angle to the nearest whole degree is 72 degrees
