What expression is equivalent to 24a+(-26b)-13a+12b?

Measure of angle B is 36.87°.

Trigonometric functions are defined as the real functions or the periodic functions which relate an angle in a right angled triangle to the ratios of the length of two sides.

Given is a right angled triangle.

We have to find measure of angle B.

Cosine of an angle in a right angled triangle is equal to the ratio of it's adjacent side to the hypotenuse.

Hypotenuse = AB = 5

Adjacent side to B = CB = 4

Cos B = 4/5

∠B = Cos⁻¹ (4/5)

     = 0.6435 radians

     = 36.87°

Hence the measure of the angle B is 36.87°.

Answer:

m angleJ= 53, m angle JML = 63.5

Step-by-step explanation:

As this is a circle, KJ and KL are radii, which are equal

If we join J and L to form JL, Triangle KJL becomes and isosceles triangle( two sides equal).

That means, the angles J and L are equal (isosceles triangle thm).

Therefore- m angleJ = 180 - 127

m angleJ = 53

Join J and K, and L and K

Another circle theorem- The angle subtended by an arc/chord on the centre is double the angle subtended by the chord on any other point on the circle.

Therefore- angle JML  = (1/2)127
So, m angleJML = 63.5

The absolute value function on the graph is:

f(x) = -|x + 4| - 5

Remember that an absolute value function that has a vertex at (a, b) will be written as:

f(x) = |x - a| + b

Here the vertex is at (-4, -5), replacing that in the general formula we will get:

f(x) = |x + 4| - 5

And we also can see that the absolute value function opens downwards with slopes of 1, then there must be a leading coefficient of -1, the actual function is:

f(x) = -|x + 4| - 5

Step-by-step explanation:

Answer:31.42 sq.

Step-by-step explanation:

To find a polynomial function of degree 3 such that f(10) = 17 and the zeros of f are 0, 5, and 8, we can use the factored form of the polynomial. The polynomial can be written as f(x) = (17/20)x(x - 5)(x - 8).

If the zeros of a polynomial function are 0, 5, and 8, then the factored form of the polynomial can be written as: f(x) = k(x - 0)(x - 5)(x - 8)

To find a polynomial function of degree 3 such that f(10) = 17 and the zeros of f are 0, 5, and 8, we can use the factored form of a polynomial. The factored form of a polynomial is the product of its factors, which are its linear binomials that correspond to its zeros.

For example, if a polynomial has zeros of 1, 2, and 3, then its factored form can be written as (x - 1)(x - 2)(x - 3). We can use this concept to find the factored form of the polynomial with zeros of 0, 5, and 8, which is:

f(x) = k(x - 0)(x - 5)(x - 8)

where k is a constant coefficient that we need to determine. We can use the given condition that f(10) = 17 to solve for k. When we plug in x = 10, we get:

f(10) = k(10 - 0)(10 - 5)(10 - 8) = 2k * 5 * 2 = 20k

Since f(10) = 17, we can set 20k = 17 and solve for k:

k = 17/20

Therefore, the polynomial function of degree 3 with the given conditions is:f(x) = (17/20)x(x - 5)(x - 8)

So the temperature in City A was 8A C and the temperature in City B was y = x + 1 = 8 + 1 = 9A C.

The problem can be solved by setting up an equation using the information given. Let's call the temperature of City A "x" and the temperature of City B "y". We can then write two equations based on the information given:

4x = 3y + 8

x - 2y = -3

We can use substitution to solve for one of the variables and then use that information to solve for the other. For example, we can substitute 3y + 8 for 4x in the second equation:

x - 2y = -3

x - 2y = 3y + 8 - 3

x - 2y = 3y + 5

x - 5y = 5

We can then solve for y by multiplying both sides of the equation by -1/5:

-5x + 5y = -5

5y = 5x + 5

y = x + 1

We can then substitute this expression for y into one of the original equations and solve for x:

4x = 3(x + 1) + 8

4x = 3x + 3 + 8

x = 8

So the temperature in City A was 8A C and the temperature in City B was y = x + 1 = 8 + 1 = 9A C.

A ratio has two or more numbers that symbolize relation to each other. Ratios are used to compare numbers, and you can compare them using division.

To find the ratio of the problem (days: pages) we can use this equation:

pages read ÷ days it took = pages read each day

Fitting the numbers into the equation:

168 ÷ 7 = 24

So, everyday Kelly reads 24 pages.

To find out how many more days Kelly needs to read, if she reads at the same rate, we can use this equation:

(456 - 168) ÷ 24 = days left

We can use this to check our work:

168 + (24 ×?) = 456

Solving for the first equation:

(456 - 168) ÷ 24 = days left

288 ÷ 24 = 12

Now, we can check our work.

168 + (24 ×?) = 456

Inserting 12 into the equation:

168 + (24 × 12) = 456

168 + 288 = 456

Therefore, to complete the book it will take Kelly 12 more days.

5 additional trees give maximum yield and 35 trees per acre will give largest crop of apple.

Let's assume that, we are planting x apple trees extra per acre. So, net 10x apple will be less.

Let say, total number of apples = y

Then, y = (30+x)×(400–10x)

For, optimum number of trees, let's do the differentiation of the above equation with respect to x.

d(y)/d(x) = (400–10x)×1 + (30+x)×(-10)

= 400–10x-300–10x

= 100–20x …………..(1)

For mimima or maxima, the above equation must be equal to 0.

So, 0 = 100–20x

=> x=5

Let's do the second differentiation of equation (1) and substitute the the value of x I.e x=5

[tex]d^2(y)/d(x^2) = -20[/tex]

The above equation is negative for all values of x which indicates that at x=5 we will have the maximum value.

So, the number of trees for maximum apple will be (30+x)

So, 30+5 = 35 trees per acre will give the largest crop of apple.

Hence 5 additional trees give maximum yield and 35 trees per acre will give largest crop of apple.

The temperature at 3 AM is about 53 degrees Fahrenheit.

The average kinetic energy of the particles in a medium, such as a gas, liquid, or solid, is measured by its temperature. It is a basic physical characteristic that governs the rate and amount of heat transmission between two bodies that are in thermal contact.

A thermometer is commonly used to measure temperature. It does this by detecting changes in a substance's physical characteristics that change with temperature, such as the expansion or contraction of a liquid or the resistance of a wire.

We are aware that a sinusoidal function models temperature, and the following information is crucial:

A high of 80 degrees is reached at 5 PM, or 17:00 in a 24-hour period.

The day's average temperature is 60 degrees.

We're looking for the temperature at three in the morning, or three in 24-hour time.

We can utilize the fact that the temperature moves through one full cycle in a 24-hour day to determine the frequency. As the time frame is 24 hours, the frequency is:

B = 2π/24 = π/12

To find the phase shift, we can use the fact that the high temperature occurs at 5 PM, which is 8 hours after noon (when the temperature starts to rise). So the phase shift is:

C = (8/24) * 2π = (1/3)π

To find the amplitude, we can use the fact that the temperature swings 10 degrees above and below the average. So the amplitude is:

A = 10

Finally, we can use the formula to find the temperature at 3 AM:

f(x) = A sin(B(x - C)) + D

f(3) = 10 sin(π/12(3 - (1/3)π)) + 60

f(3) ≈ 53.4

So the temperature at 3 AM is about 53 degrees Fahrenheit.

The probability of a college student being either female or having financial aid can be expressed as P(A ∪ B) = P(A) + P(B).

What is Probability?

Probability is a mathematical concept used to measure the likelihood of a particular event occurring. It is a way of expressing the chance or possibility of an event happening, ranging from 0 (impossible) to 1 (certain).

In probability theory, an event is a subset of the possible outcomes of an experiment or a random process. Probability can be expressed in terms of fractions, percentages, or decimals.

The symbol for the event that a college student is female is A, as given in the statement. The symbol for the event that a college student has financial aid is B, as given in the statement.

So, A={A student is female} and B={A student has financial aid}.

These events are mutually exclusive because one does not necessarily affect the other. For example, a male student can have financial aid and a female student may not have financial aid. Hence, the occurrence of one event does not influence the occurrence of the other event.

Therefore, the probability of a college student being either female or having financial aid can be represented as the union of the events A and B. It can be denoted as P(A ∪ B) and is calculated as:

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

Where P(A ∩ B) represents the probability of a student having both characteristics, i.e., being female and having financial aid.

However, as these events are mutually exclusive, P(A ∩ B) = 0. So the probability of a college student being either female or having financial aid is simply the sum of their individual probabilities:

P(A ∪ B) = P(A) + P(B) - 0

P(A ∪ B) = P(A) + P(B)

Hence, the probability of a college student being either female or having financial aid can be expressed as P(A ∪ B) = P(A) + P(B).

Let's say that Armer Brown used x bags holding 20 oranges, y bags holding 10 oranges, and z bags holding 5 oranges. We know that he harvested 245 oranges, so we can write an equation:

20x + 10y + 5z = 245
