Let ABC be the given triangle. We can construct two triangles PAB and PBC such that they share the same height from P to AB and P to BC, respectively. We can label the side lengths of PAB and PBC as x and y, respectively. The total area of the triangle ABC is the sum of the areas of PAB and PBC:

Area_ABC = Area_PAB + Area_PBC We can write the area of each of the sub-triangles in terms of x and y by using the formula for the area of a triangle: Area_PAB = (1/2)(12)(x) = 6xArea_PBC = (1/2)(15)(y) = (15/2)y Setting the areas equal to each other and solving for y yields: y = (4/5)x Substituting this into the equation for the area of PBC yields:

Area_PBC = (1/2)(15/2)x = (15/4)x The area of ABC can also be written in terms of x by using the formula: Area_ABC = (1/2)(AB)(PQ) = (1/2)(12)(PQ) + (1/2)(15)(PQ) = (9/2)(PQ) Setting the areas equal to each other yields:(9/2)(PQ) = 6x + (15/4)x(9/2)(PQ) = (33/4)x(9/2)(PQ)/(33/4) = x(6/11)PQ = x(6/11)Thus, we can see that the longest possible integer length of the third altitude is $\boxed{66}$.

Step-by-step explanation:

Need to know how many ounces in a scoop of pig food. Is there a ratio or formula associated? Lmk.

a. f'(x) = 40x³

To find the derivative of f(x) = 10x⁴, we apply the power rule.

The power rule states that if f(x) = axⁿ, then f'(x) = naxⁿ⁻¹. Applying this rule, we get f'(x) = 4 * 10x³ = 40x³.

b. : f'(x) = 20 + 90x²

To find the derivative of f(x) = 20x + 30x³, we differentiate each term separately. The derivative of 20x is 20, and the derivative of 30x³ is 90x² (applying the power rule). Adding these derivatives, we get f'(x) = 20 + 90x².

r: f'(x) = (20x - 4x²)(5x - x²) + (10 + 2x²)(-2x + 5)

To find the derivative of f(x) = (10 + 2x²)(5x - x²), we apply the product rule. The product rule states that if f(x) = g(x) * h(x), then f'(x) = g'(x) * h(x) + g(x) * h'(x). Differentiating each term, we get f'(x) = (20x - 4x²)(5x - x²) + (10 + 2x²)(-2x + 5).

d.: f'(x) = 40x

To find the derivative of f(x) = 20x / (x²), we use the quotient rule. The quotient rule states that if f(x) = g(x) / h(x), then f'(x) = (g'(x) * h(x) - g(x) * h'(x)) / (h(x)²). In this case, g(x) = 20x and h(x) = x². After differentiating and simplifying, we obtain f'(x) = 40x.

Answer:

4th triangle

Step-by-step explanation:

The correct answer for the given problem above would be the fourth triangle. So here is the given solution: Since Triangle 1 is already given with a measurement of 50 inches, and 80% of 50 inches if 40. Triangle 2 then is 40 inches. 80% of 40 is 32, so triangle 3 is 32 inches, and then 80% of 32 is 25.6 inches so triangle 4 is 25.6 inches. Therefore, the triangle that will first have a side length of less than 29 inches is triangle 4.

There are five possible outcomes: H, TH, TTH, TTTH, and TTTT, where H stands for head and T stands for tail. Among these outcomes, H occurs only once,

(a) The number of heads before the first tailWhen tossing a fair coin four times, we need to determine the probability of tossing a head before the first tail occurs.

Here, we can assume that each toss is independent, meaning that the outcome of one toss does not heads the outcome of the other tosses.

There are five possible outcomes: H, TH, TTH, TTTH, and TTTT, where H stands for head and T stands for tail. Among these outcomes, H occurs only once,

TH occurs twice, TTH occurs twice, and TTTH and TTTT each occurs only once. Thus, the frequency function for the number of heads before the first tail can be determined as follows:X: 0 1 2 3 4f(X): 1 2 2 1 0The cumulative distribution function (CDF) can be calculated by summing up the probabilities of each outcome up to and including the current value of X:

FX: 0 1 2 3 4F(X): 0 1/16 5/16 13/16 1(b) The number of heads following the first tailSimilarly,

we can determine the frequency function and the cumulative distribution function for the number of heads that occur following the first tail.

Again, we can assume that each toss is independent, meaning that the outcome of one toss does not affect the outcome of the other tosses.

There are four possible outcomes: T, HT, HHT, and HHHT, where H stands for head and T stands for tail. Among these outcomes,

T occurs only once, HT occurs twice, HHT occurs twice, and HHHT occurs only once. Thus, the frequency function for the number of heads following the first tail can be determined as follows:

Y: 0 1 2 3f(Y): 1 2 2 0The cumulative distribution function (CDF) can be calculated by summing up the probabilities of each outcome up to and including the current value of Y:GY: 0 1 2 3G(Y): 0 1/2 3/4 1

The surface integral of the function g(x, y, z) over the surface S is evaluated.

To evaluate the surface integral, we consider the rectangular prism formed by the coordinate planes and the planes x = 2, y = 2, z = 3. This prism encloses a six-sided surface S. The surface integral of a function over a surface measures the flux or flow of the function across the surface.

In this case, we are integrating the function g(x, y, z) over the surface S. The specific form of the function g(x, y, z) is not provided in the given question. To evaluate the surface integral, we need to know the expression of g(x, y, z).

Once we have the expression for g(x, y, z), we can set up the integral by parameterizing the surface S and calculating the dot product of the function g(x, y, z) and the surface normal vector. The integral will involve integrating over the appropriate range of the parameters that define the surface.

Without the specific expression for g(x, y, z) or further details, it is not possible to provide the exact numerical evaluation of the surface integral. However, the general procedure for evaluating a surface integral involves parameterizing the surface, setting up the integral, and then performing the necessary calculations.

The box's CA measures 4.7 cm in length.

Given data;

△ABC has a right angle at C, BC = 9.2 centimeters, and ∠A=63°

To know CA;

Let CA = x

As per the given case,

In a triangle sum of angles = 180°

90° + 63° + C = 180°

C = 27°

Now,

From the △ABC;

tan 63° = 9.2/x

x = 9.2/tan 63°

x = 4.687

x = 4.7

Therefore, the length of CA in the box is 4.7 cm

"The multiplier for 0.85% growth is calculated by adding 1 to the percentage as a decimal:

Multiplier for 0.85% growth = 1 + 0.0085 = 1.0085

The multiplier for 300% growth is calculated in the same way:

Multiplier for 300% growth = 1 + 3.00 = 4.00

Therefore, the multipliers for 0.85% and 300% growth are 1.0085 and 4.00, respectively." (ChatGPT, 2023)

Using alternating and corresponding angle theorems, the values of x are 11, 4, -4 and 10 respectively

Alternate angle theorem states that when two parallel lines are cut by a transversal, then the resulting alternate interior angles or alternate exterior angles are congruent.

1)

9x + 8 = 107 (alternating angles are equal)

9x + 8 = 107

9x = 107 - 8

9x = 99

x = 11

2)

20x = 80 (alternating angles are equal)

20x = 80

x = 4

3)

x + 84 = 80 (corresponding angles are equal)

x = 80 - 84

x = -4

4) 120 + 6x = 180

This is gotten from applying alternating angle theorem and angle on a straight line theorem

120 + 6x = 180

6x = 180 - 120

6x = 60

x = 10

Answer:

84°

Step-by-step explanation:

angles in a quadrilateral add to 360°. 360-(114+76)=5x =170°. 170°/5 = 32°. x=32°

angles on a straight line add to 180°.

2x = 64°. 180-64=116°. y=116°.

y-x = 116-32 = 84°

Answer:

\(78\)

Step-by-step explanation:

The inner angles of a quadrilateral all add up to 360. This means we can write the following

\(114 + 76 + 3x + 2x = 360\\190 + 5x = 360\\5x = 170\\x = 34\)

Now that we have x we can find y. Notice that y and 2x are on the same line. Any line cutting another straight line will create two angles that add up to 180.

Therefore we can write

\(2x + y = 180\\2(34) + y = 180\\y = 112\)

Finally computing y - x

\(y - x = 112 - 34 = 78\)
