Answer:

  Ms finch has the higher ratio

Step-by-step explanation:

Given ratios 2 : 6 and 3 : 5, you want to know which is greater.

There are several ways to compare ratios. You can express them over a common denominator, compare them to a common value, convert them to decimal, subtract one from the other.

  2 : 6 vs 3 : 5 = 10 : 30 vs 18 : 30

3 : 5 is greater than 2 : 6, so Ms finch has the higher ratio.

  2 : 6 vs 3 : 5

We can compare each of these to 1/2.

  2 : 6 < 3 : 6 = 1/2

  3 : 5 > 2.5 : 5 = 1/2

3 : 5 is greater than 2 : 6, so Ms finch has the higher ratio.

  2 : 6 ≈ 0.333

  3 : 5 = 0.600

3 : 5 is greater than 2 : 6, so Ms finch has the higher ratio.

  2/6 -3/5 = (10 -18)/(30) = -8/30 so the second ratio is higher

3 : 5 is greater than 2 : 6, so Ms finch has the higher ratio.

Therefore , the required inequality expression is 4.50x+1.75y ≤50

A mathematical expression is made up of a statement, at least two integers or variables, and one or more arithmetic operations.. This mathematical operation enables the multiplication, division, addition, or subtraction of numbers.An expression's structure is as follows: Expression: (Math Operator, Number/Variable, Math Operator)

One cupcake costs $4.50,

So, “x” cupcakes cost = 4.50x.

One brownie cost $1.75,

so “y” brownies cost = 1.75y.

thus, the total 4.50x+1.75y  must be less or equal to $50.

Therefore , the required inequality expression is 4.50x+1.75y ≤50

Step-by-step explanation:

Let's call the initial distance from the jet to the airport $x$. We are told that $x = 5$ miles.

Let's call the initial ground distance from the projection of the jet onto the ground to the airport $y$. We are told that $y = 4$ miles.

Let's call the rate at which the distance from the jet to the airport is increasing $v_x$. We are told that $v_x = 180$ miles/hour.

Let's call the rate at which the ground distance from the projection of the jet to the ground to the airport is increasing $v_y$. We are told that $v_y = 150$ miles/hour.

We want to find the vertical speed of the jet at this moment in time. Let's call this quantity $v_z$.

Since the jet is flying in the eastward direction, we can use the Pythagorean theorem to relate the three sides of the right triangle formed by the jet, the projection of the jet onto the ground, and the airport. Specifically, we have

$$x^2 = y^2 + z^2$$

where $z$ is the vertical distance from the jet to the ground (i.e., the height of the jet above the ground).

Since the distance from the jet to the airport and the ground distance from the projection of the jet to the airport are both increasing, we can take the derivative of both sides of the equation above to find the rate of change of $z$ with respect to time. This gives us

$$2x \frac{dx}{dt} = 2y \frac{dy}{dt} + 2z \frac{dz}{dt}$$

where $t$ is time.

We are given the values of $x$, $y$, $v_x$, and $v_y$, so we can plug these values into the equation above to solve for $v_z$. This gives us

$$2 \cdot 5 \cdot 180 = 2 \cdot 4 \cdot 150 + 2z \frac{dz}{dt}$$

Solving for $\frac{dz}{dt}$, we get

$$\frac{dz}{dt} = \frac{2 \cdot 5 \cdot 180 - 2 \cdot 4 \cdot 150}{2z}$$

We are told that $z = x - y$, so we can plug this into the equation above to find $\frac{dz}{dt}$. This gives us

$$\frac{dz}{dt} = \frac{2 \cdot 5 \cdot 180 - 2 \cdot 4 \cdot 150}{2(x-y)}$$

Substituting the values of the known quantities, we get

$$\frac{dz}{dt} = \frac{2 \cdot 5 \cdot 180 - 2 \cdot 4 \cdot 150}{2(5-4)} = \frac{180}{2} = 90$$

Therefore, the vertical speed of the jet at this moment in time is $v_z = 90$ miles/hour.

The vertical speed of the jet is approximately 300 miles/hour.

Velocity is the pace and direction of an item's movement, whereas speed is the time rate at which an object is traveling along a route.

Let's call the distance from the jet to the airport "d" and the height of the jet "h". Then we have two related rates:

d is increasing at a rate of 180 miles/hour.

The horizontal distance is increasing at a rate of 150 miles/hour.

Using the Pythagorean theorem, we can relate these two distances:

d² = h² + 4²

Taking the derivative of both sides with respect to time, we get:

2d(dd/dt) = 2h(dh/dt)

Simplifying, we get:

dd/dt = (h/d)(dh/dt)

We're looking for the vertical speed of the jet, which is dh/dt. We can solve for this by plugging in the given values:

d = 5 miles

dd/dt = 180 miles/hour

h² + 4² = 5² (from the Pythagorean theorem)

dh/dt = ?

Solving for h, we get:

h² = 5² - 4² = 9

h = 3 miles

Now we can plug in all the values and solve for dh/dt:

dh/dt = (dd/dt)(d/h) = (180 miles/hour)(5 miles/3 miles) ≈ 300 miles/hour

The linear approximation found to estimate ln(0.97) is 9.1%.

The definition of a linear approximation of a function is simply utilising a line to approximate the value of the function at a point. We recall the idea of the tangent line as soon as we see a curve (of a function) and a point on it. The value of the function at any point that is very close to the provided point can be roughly determined using the equation of the tangent line if the equation of the tangent line is found at the supplied point.

The given function is f(x) = ln(x).

We start by finding the equation of the tangent line at x=1 to the graph of y=lnx.

f(1)=ln(1)=0

We know the derivative of f(x) will be f'(x)=1/x

f'(1)=1/1=1

Therefore, the equation of the tangent is:y−y1=m(x−x1)

y−0=1(x−1)

y=x−1

An approximation for ln(1.19) would be y=1.19−1=0.19

The actual value, obtained using a calculator, would be 0.174. This means the percent error is (0.19−0.174)/0.174 ×100

= 9.1%

Therefore, the linear approximation found to estimate ln(0.97) is 9.1%.
