The values of 65 euros is 76.70 US dollars.

To convert 65 euros to dollars, you need to know the current exchange rate between the two currencies. As of September 2021, the exchange rate is 1 euro = 1.18 US dollars.

To calculate the conversion, you can simply multiply the amount of euros by the exchange rate.

65 euros x 1.18 US dollars = 76.70 US dollars

Therefore, 65 euros is equivalent to 76.70 US dollars.

It's important to note that exchange rates can fluctuate, so the conversion may not be the same in the future. It's always best to check the current exchange rate before making a conversion.

One mile is equal to 5,280 feet. Therefore, to convert the altitude of Denver from miles to feet, we can multiply by 5,280:

1 mile × 5,280 feet/mile = 5,280 feet

So, Denver's altitude of 1 mile is equal to 5,280 feet.

Step-by-step explanation:

We can find the other point using the axis of symmetry.

The axis of symmetry for a parabola passes through the x coordinate of the vertex.

So our axis of symmetry is x=4, which is a vertical line.

For any point on a parabola curve except the vertex, there will two points that share the same y value. The two x coordinates of those points midpoints should be the axis of symmetry.

So,

If we know (0,-6) and the vertex is 4, let's find the other point

[tex]( \frac{0 + b}{2} = 4[/tex]

[tex]b = 8[/tex]

So our other point is

(8,-6).

So the answer to #1 is we found point (8,-6) by using the axis of symmetry. By reflecting the point (0,-6) about the vertical line x=4, we end up getting the point (8,-6)

To find q, q(x) has the same vertex, so it is (4,10).

We know the axis of symmetry is x=4, we also know the y intercept is 18 so we have point (0,18)

Using the axis of symmetry we will get (8,18).

So the graphs above are the graphs of p and q

The graph facing upwards is q

The graph facing downwards is p.

For #2, you can say we know the vertex is (4,10) and using the y intercept and axis of symmetry we found the other point on the curve.

I don't fully see the table but if the other coordinates have a higher y value, the vertex is a minimum.

Else, of the other coordinates have a lower y value, the vertex is a maximum.

The numbers of flowers spaced every 4 feet, are needed

to surround a circular garden with a 70-foot radius, 105

Circumference is the distance around the perimeter of a circular object. It is defined as the length of the circle that is found by multiplying the diameter of the circle by π (pi), which is approximately equal to 3.14.

The formula for the circumference of a circle is given by:

C = 2πr,

To calculate the circumference of the circular garden, we can use the formula:

C = 2πr

where C is the circumference, π is the mathematical constant pi (approximated as 3 in this case), and r is the radius. Plugging in the given values, we have:

C = 2 x 3 x 70

  = 420 feet

Now, since the flowers are spaced every 4 feet, we can divide the circumference by 4 to find the number of flowers needed:

number of flowers = C / 4

                               = 420 / 4

                               = 105

Therefore, 105 flowers spaced every 4 feet are needed to surround a circular garden with a 70-foot radius.

The height of the cylindrical tub of ice cream is 6.75 inches.

A cylinder is a 3 dimensional shape which has a curved side and two circular surfaces. The total surface area can be determined by the expression;

total surface area of a cylinder = 2πr^2 + 2πrh

where r is the radius of it circular surface, and h is its height.

Considering the given question, we have;

total surface area of a cylinder = 2πr^2 + 2πrh

But total surface area = 183.69 square inches

r = D/2

  = 6/ 2

r = 3 inches

Thus,

183.69 = 2*3.14*3^2 + 2*3.14*3*h

           = 56.52 + 18.84h

183.69 - 56.52 = 18.84h

127.17 = 18.84h

h = 127.17/ 18.84

  = 6.75

Answer: The answer is (C) 6.75

Step-by-step explanation:

The formula for Surface Area is: SA = 2πr^2 + 2πrh

Let's do the first part: 2πr^2

So you need to find the radius, which is half the diameter. 6 is the diameter so half that, and you get 3.

Now, times 3 by itself

3 * 3 = 9

And then times 9 by 2

9 * 2 = 18

And times 18 by pi, 3.14

18 * 3.14 = 56.52

Now that we have our first value, lets move on to the second part of the formula: 2πrh

So we need the diameter, and the question gives us the value of the diameter.

6 is the diameter

so times 6 by pi, 3.14

6 * 3.14 = 18.84h  (leave h there because we don't know the height)

Now do this:

183.69 =  56.52 + 18.84h

You cannot add 56.52 and 18.84h because they are not like terms

So take away 56.52 from both sides

56.52 - 56.52 = 0

183.69 - 56.52 = 127.17

Now divide 127.17 by 18.84h

127.17/18.84  = 6.75 inches

The integration of the given equation will be [(1/2) i√3 + 2 log (1 + 3i)].

Integration is a way of finding the total by adding or summing the components. It's a reversal of differentiation, in which we break down functions into pieces. This approach is used to calculate the total on a large scale.

The integration equation is given below.

[tex]\begin{aligned} \rm I = \int _1^2 \sqrt{x^2 - 4} \ dx \end{aligned}[/tex]

We know that the formula is given as,

∫√(x² - a²) dx = (x/2)√(x² - a²) + (a² / 2) log [x + √(x² - a²)]

Then by the integration, we can write it as,

[tex]\begin{aligned} \rm I &= \int _1^2 \sqrt{x^2 - 4} \ dx \\\rm I &= \int _1^2 \sqrt{x^2 - 2^2} \dx\\\rm I &= \left [ \dfrac{x}{2}\sqrt{x^2-2^2} + \dfrac{2^2}{2} \log (x + \sqrt{x^2 - 2^2}) \right ]^2_1\\\end{aligned}[/tex]

A. The equation is given as C = 0.1T + 0.05M

B. It will cost Laura $1.05 to send 4 texts and talk for 13 minutes.

C. Laura will have $1.80 left after sending 18 texts and talking for 124 minutes.

D. The equation for T is T = (C - 0.05M) / 0.1.

A. The equation for the cost, C, of sending both texts and talking for M minutes is:

C = 0.1T + 0.05M

where T is the number of texts sent.

This equation assumes that each text costs 10 cents and each minute of talk time costs 5 cents.

B. To calculate the cost of sending 4 texts and talking for 13 minutes, we can use the equation from part A:

C = 0.1T + 0.05M

C = 0.1(4) + 0.05(13)

C = 0.4 + 0.65

C = 1.05

Therefore, it will cost Laura $1.05 to send 4 texts and talk for 13 minutes.

C. To determine how many minutes Laura can talk if she wants to send 18 texts and only has eight dollars, we need to use the equation from part A and solve for M:

C = 0.1T + 0.05M

8 = 0.1(18) + 0.05M

8 = 1.8 + 0.05M

6.2 = 0.05M

M = 124

Therefore, Laura can talk for 124 minutes if she wants to send 18 texts and has eight dollars.

This will cost her $6.20, which is less than the amount of money she has, so she will have some money left over.

subtract the cost of talking and texting from the amount of money she has:

Money left = 8 - 6.20

Money left = 1.80

Therefore, Laura will have $1.80 left after sending 18 texts and talking for 124 minutes.

D. To solve the equation from part A for T, we can rearrange the terms:

C = 0.1T + 0.05M

0.1T = C - 0.05M

T = (C - 0.05M) / 0.1

Therefore, the equation for T is T = (C - 0.05M) / 0.1.
