The temperature difference between Rome and Munich is [tex]2[/tex]°C in the first case.

a) To find the difference in temperature between Rome and Munich, we compare their respective temperatures on the bar chart. Let's assume the temperatures on the chart are represented by the heights of the bars. From the chart, the temperature in Rome is [tex]10[/tex]°C, and the temperature in Munich is [tex]8[/tex]°C.

The difference in temperature between Rome and Munich can be calculated as the absolute difference between their values:

[tex]\[ \text{Difference in temperature} = |10 - 8| = 2°C \][/tex]

Therefore, the temperature difference between Rome and Munich is [tex]2[/tex]°C.

b) If the temperature in Oslo rises by [tex]5[/tex]°C over the next [tex]6[/tex] hours, we can add this increase to the current temperature in Oslo to determine the temperature at [tex]6[/tex] pm. However, the initial temperature in Oslo is not provided in the information given.

Without the initial temperature, we cannot calculate the specific temperature at [tex]6[/tex] pm.

Answer: To find the exponential growth of the coin's value over the given period, we can use the formula for exponential growth:

V(t) = V0 × e^(kt)

where V(t) is the value of the coin at time t, V0 is the initial value of the coin, e is the mathematical constant e (approximately equal to 2.71828), k is the growth rate, and t is the time period.

We can use the information given to find the value of k. Let's use 1977 as the initial time period and 1990 as the final time period. The value of the coin in 1977 is V0 = $279, and the value of the coin in 1990 is V(13) = $434 (since 1990 - 1977 = 13 years).

Substituting these values into the formula, we get:

$434 = $279 × e^(k × 13)

Dividing both sides by $279, we get:

e^(k × 13) = $434 / $279

Taking the natural logarithm of both sides, we get:

k × 13 = ln($434 / $279)

Simplifying, we get:

k = ln($434 / $279) / 13

Using a calculator, we find that k is approximately 0.0556.

Now that we have found the growth rate, we can use the formula to find the value of the coin at any time t. For example, to find the value of the coin in 1985 (8 years after 1977), we can use the formula:

V(8) = $279 × e^(0.0556 × 8)

Using a calculator, we find that V(8) is approximately $425.46.

Therefore, we can conclude that the value of the coin grew exponentially at a rate of approximately 5.56% per year, and was worth about $425.46 in 1985.

Answer:

To find the equation in standard form for the circle that has a diameter with endpoints (4,-7) and (-12,-7), we first need to find the center and radius of the circle.

The center of the circle is the midpoint of the diameter, which can be found using the midpoint formula:

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

Where (x1, y1) and (x2, y2) are the coordinates of the endpoints of the diameter.

Using (4,-7) and (-12,-7) as the endpoint coordinates, we get:

Midpoint = ((4 + (-12))/2, (-7 + (-7))/2) = (-4, -7)

So the center of the circle is (-4, -7).

The radius of the circle is half the length of the diameter, which is:

Radius = 1/2 × distance between (4,-7) and (-12,-7)

Radius = 1/2 × (4 - (-12)) = 8

So the radius of the circle is 8.

Now we can write the equation of the circle in standard form:

(x - h)² + (y - k)² = r²

Where (h,k) is the center of the circle and r is the radius.

Substituting the values we found, we get:

(x - (-4))² + (y - (-7))² = 8²

Simplifying this equation, we get:

(x + 4)² + (y + 7)² = 64

Therefore, the equation in standard form for the circle that has a diameter with endpoints (4,-7) and (-12,-7) is (x + 4)² + (y + 7)² = 64.

Answer:

Step-by-step explanation:

To solve this problem, we need to first convert the distance on the map to actual distance using the map scale.

1 cm on the map represents 50,000 cm (or 500m) in actual distance.

So, 8.5 cm on the map represents 8.5 x 500m = 4,250m in actual distance.

Now, we can use the formula: time = distance ÷ speed

Here, distance = 4,250m and speed = 10km/h = 10,000m/h

So, time = 4,250m ÷ 10,000m/h = 0.425 hours

To convert hours to minutes, we can multiply by 60:

time = 0.425 x 60 = 25.5 minutes

Therefore, it will take Myra 25.5 minutes to run from the park entrance to the beach.

In Mathematics, the basic proportionality theorem states that when any of the two (2) sides of a triangle is intersected by a straight line which is parallel to the third (3rd) side of the triangle, then, the two (2) sides that are intersected would be divided proportionally and in the same ratio.

By applying the basic proportionality theorem to the given triangle, we have the following:

4/x = 6/2

Answer:

derivative of cosx/sin2x is (1 + secx) / [2sinx cosx].

Step-by-step explanation:

To differentiate cosx/sin2x, we can use the quotient rule of differentiation, which states:

(d/dx) [f(x)/g(x)] = [g(x) * f'(x) - f(x) * g'(x)] / [g(x)]^2

Here, f(x) = cosx and g(x) = sin2x. So we have:

f'(x) = -sinx (differentiation of cosine)

g'(x) = 2cos2x (differentiation of sine2x using chain rule)

Now, using the quotient rule:

(d/dx) [cosx/sin2x] = [sin2x * (-sinx) - cosx * (2cos2x)] / [sin2x]^2

= [-2cos2x cosx + sin2x sinx] / [sin2x]^2

= [-2cosx cos2x + sinx] / [2sinx cosx]^2

= [-2cosx(1-2sin^2(x)) + sinx] / [2sinx cosx]^2

= [-2cosx + 4cosx sin^2(x) + sinx] / [2sinx cosx]^2

= (sinx + 2cosx sin^2(x)) / [2sinx cosx]^2

= sinx / [2sinx cosx]^2 + 2cosx / [2sinx cosx]^2

= 1/[2sinx cosx] + secx/[2sinx cosx]

= (1 + secx) / [2sinx cosx]

Therefore, the derivative of cosx/sin2x is (1 + secx) / [2sinx cosx].

P(X = 14) = (n choose k) * p^k * (1-p)^(n-k)

where n is the number of trials,

p is the probability of success, and

k is the number of successes.

Plugging in the given values, we have:

The area of the triangle ∆NOP is derived to be 133.9 square centimeter to the nearest tenth using the sine rule.

The sine rule is a relationship between the size of an angle in a triangle and the opposing side. It states that for any triangle ABC, the ratio of the length of a side to the sine of the angle opposite that side is constant, that is;

a/sinA = b/sinB = c/sinC

where a, b, and c are the lengths of the sides of the triangle, and A, B, and C are the measures of the angles opposite those sides.

angle m∠O = 180 - (83 + 88) {sum of interior angles of a triangle}

angle m∠O = 9°

Using the sine rule;

6.5/sin9 = ON/sin88

ON = (6.5 × sin88°)/sin9 {cross multiplication}

The inverse function of f(n) is:

Two functions are inverses if the composition is equal to the identity, so if g(n) is the inverse of f(n), we must have that:

f( g(n) ) = n

Replacing the actual function we will get:

-2 - (7/3)*g(n) = n

Now we can solve this for the inverse function g(n), then we will get:

-2 - (7/3)*g(n) = n

(-7/4)*g(n) = n + 2

Answer:

B: 1/3 log (2-x) - log 3x

Step-by-step explanation:

some log laws:

1) log xy = log x + log y

2) log (x/y) = log x - log y

3) log x^k = k log x

log ((∛2-x) / 3x)

= log ∛2-x  -  log 3x  (just like the 2nd law above)

log ∛2-x = log (2-x)^(1/3)  =  (1/3) log (2-x)   (just like the 3rd law above).
