CM is the perpendicular bisector of AB at M, it means that CM is perpendicular to AB, and AM=BM. Therefore, we have two right triangles, triangle AMC and triangle BMC, with a shared side CM, and AM=BM.

By the Pythagorean theorem, we know that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. Applying this to triangles AMC and BMC, we have:

AC² = AM² + CM²

BC² = BM² + CM²

Since AM=BM, we can substitute AM for BM in the second equation, giving:

BC² = AM² + CM²

Since the left-hand sides of these two equations are equal (by the given that CM is the perpendicular bisector of AB), we can set their right-hand sides equal to each other and simplify:

AC² = BC²

Taking the square root of both sides gives us:

AC = BC

On solving the provided question we can say that - the removable discontinuity of f(x) located is -5

Discontinuous functions in graphs are those that have no connections to one another. Discontinuities come in three different flavors: removable, jump, and infinite.. If the left limit and the right limit of a function, f(x), are both different, then the function has a first-kind discontinuity at x = a. a characteristic that cannot be mathematically continuous. Continuous functions allow you to sketch without having to lift your pen. In such a case, the function is said to as discontinuous.

here,

f(x) = \(\frac{x+5}{x^2+3x-10}\)

\(x^2+3x-10\)

x(x+5) - 2(x+5)

The quantity of substance remains after 850 years is 8.98g if the half life of radioactive radium is 1,599 years.

The time taken by substance to reduce to its half of its initial concentration is called half life period.

We will use the half- life equation N(t)

N e^{(-0.693t) /t½}

Where,

N is the initial sample

t½ is the half life time period of the substance

t2 is the time in years.

N(t) is the reminder quantity after t years .

Given

N = 13g

t = 350 years

t½ = 1599 years

By substituting all the value, we get

N(t) = 13e^(0.693 × 50) / (1599)

= 13e^(- 0.368386)

= 13 × 0.691

= 8.98

Thus, we calculated that the quantity of substance remains after 850 years is 8.98g if the half life of radioactive radium is 1,599 years.

Answer: 4 boxes of baseballs weigh 120 pounds and 400 boxes weigh 12,000 pounds.

Step-by-step explanation:

We know that 40 boxes of baseballs weigh a total of 1,200 pounds.

So we can just that the unit rate of this by doing 1,200/40 = 30

After that we get that 1 box of baseballs weigh 30 pounds.

Next to find out how much 4 boxes of baseballs weigh we do 30 * 4 = 120 pound.

Lastly to find out how much 400 boxes of baseballs weigh we do 30 * 400 = 12,000 pounds

The work done by the force field f(x, y) = xi (y 1)j in moving an object along an arch of the cycloid

r(t) = (t − sin(t))i (1 − cos(t))j, 0 ≤ t ≤ 2 is -4

To find the work done by the force field in moving an object along the arch of the cycloid r(t), we need to compute the line integral of the dot product of the force field with the unit tangent vector of the arch. The cycloid is given by:r(t) = (t - sin(t))i + (1 - cos(t))j, 0 ≤ t ≤ 2.To find the unit tangent vector T(t), we differentiate the cycloid:

r'(t) = (1 - cos(t))i + sin(t)j.

T(t) = r'(t)/|r'(t)|

= (1 - cos(t))/√(2 - 2cos(t)) i + sin(t)/√(2 - 2cos(t)) j. The work done by the force field in moving the object along the arch is given by the line integral:W = ∫C f(r) · T(t) ds,where C is the arch of the cycloid, r is the position vector, T is the unit tangent vector, and ds is the arc length element. We have: f(x, y) = xi(y - 1)j, so f(r(t))

= (t - sin(t))i(1 - cos(t) - 1)j

= (t - sin(t))i(-cos(t))j

= -t cos(t) i + (t sin(t) - t) j.Writing this in terms of the unit tangent vector, we have:f(r) ·

T = (-t cos(t) i + (t sin(t) - t) j) · ((1 - cos(t))/√(2 - 2cos(t)) i + sin(t)/√(2 - 2cos(t)) j)

= -t cos(t) (1 - cos(t))/(2 - 2cos(t)) + (t sin(t) - t) sin(t)/(2 - 2cos(t))

= -t (cos(t) - cos²(t) + sin²(t))/(2 - 2cos(t))

= -t (cos(t) - 1)/(1 - cos(t))

= t (1 - cos(t))/(cos(t) - 1). Therefore, the work done by the force field in moving the object along the arch is:

W = ∫C f(r) · T(t) ds

= ∫0² t(1 - cos(t))/(cos(t) - 1) |r'(t)| dt

= ∫0² t(1 - cos(t))/√(2 - 2cos(t)) dt

= -∫0² t d(cos(t))

= t(cos(t) - 1) |0²

= -4. The work done by the force field in moving the object along the arch of the cycloid is -4.

Answer:

  8.5 years

Step-by-step explanation:

You want to know the number of years until 18500 depreciates to 9100 at the rate of 8% per year.

The depreciation rate given as a percentage of current value tells you the depreciation is exponential. The formula will be ...

  value = (initial value) × (1 - (depreciation rate))^t

where the rate is "per year" and t is in years.

  value = 18500·(1 -0.08)^t

  9100 = 18500·0.92^t . . . . fill in the value of interest

  9100/18500 = 0.92^t . . . . divide by 18500

  log(91/185) = t·log(0.92) . . . . take logarithms

  t = log(91/185)/log(0.92) ≈ -0.3081/-0.03621 ≈ 8.509

It will be about 8.5 years until the value is $9100.

Answer: 1. It would take your friend 24 minutes to catch up. Your friend would've walked 1.6 miles once they've caught up.

Step-by-step explanation: If you walk 2.5 miles per hour, you would have to divide that by 60 minutes to find out how fast you walk per minute. Which would be 0.04166666667 miles per minute, if you walked for 24 minutes, you would've completed a full mile. Your friend walks 4 miles per hour, you would want to divide that by 60 as well to find out how fast he walks per minute. Which would be 0.06666666667 miles per minute, if he walked for a total of 24 minutes, he would've walked for a total of 1.6 miles. Remember, you started 0.6 miles ahead of him, meaning after a total of 24 minutes, your friend would've caught up to you.

The value of x when h(x) =-3 is 5.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

h(x) = -x + 2

Now, we have to find the value of x when h(x)= -3

So, h(x)= -3

-x+ 2= -3

Now, Subtracting 2 from both side

-x+ 2 -2= -3 -2

-x = -5

x= 5

Hence, the value of x is 5.

Answer:

Step-by-step explanation:

Sum of angle in a triangle = 180°

<A+<B+<C = 180

Given <B = 50°

Substituting into the formula

<A+50+<C = 180

<A+<C = 180-50

<A+<C = 130°

Since the ∆ABC is an acute triangle, the angles <A and <C must be angles less than 90° since acute angles are angles less than 90°

The possible values of <A and <C that will be acute and give a sum of 130° are;

∠A= 58° and ∠C= 72°

∠A= 80° and ∠C= 50°

∠A= 60° and ∠C= 70°

The range of possible values for y is given as follows:

4.5 < y < 23.5.

The law of sines states that the sine of each angle is proportional to the side length opposite the angle.

For this problem, we have that:

Due to the smaller side length, the angle measure 2y - 9 has to be less than 38, hence:

2y - 9 < 38

2y < 47

y < 47/2

y < 23.5.

An angle measure has to be greater than 0, thus:

2y - 9 > 0

2y > 9

y > 9/2

y > 4.5.

Hence the range is:

4.5 < y < 23.5.

Step-by-step explanation:

The function is a set of ordered pairs (x, y), where x is an element of the domain and y is the corresponding element of the range. The notation f(x) is commonly used to denote the output value of the function for a given input value x.

At x=3, the derivative is negative, f'(3)=-12, so the function is decreasing at x=3.

The function is always decreasing since its derivative is constant and negative. Therefore, the interval where f(x) is decreasing is the entire real line, or (-∞, ∞).

Since the function is always decreasing, it does not have a relative maximum.
