[tex]cos(D)=0.51[/tex]

[tex]m\angle D=59.49^o[/tex]

Step-by-step explanation:

we know that

In the right triangle DEF

[tex]cos(D)=\frac{DF}{ED}[/tex] ---> by CAH (adjacent side divided by the hypotenuse)

substitute the given values

[tex]cos(D)=\frac{33}{65}=0.51[/tex]

using a calculator

[tex]m\angle D=cos^{-1}(\frac{33}{65})=59.49^o[/tex]

To find the value of the cosine of angle ∠D in triangle ΔDEF, use the cosine formula with the given side lengths which is 59.49 degrees.

In the given triangle ΔDEF, the measure of angle ∠F is 90°. We are given the lengths of the sides DF, FE, and ED as 33, 56, and 65 units respectively. To find the value of the cosine of angle ∠D, we need to use the cosine formula:

cos(D) = (DF2 + DE2 - EF2) / (2 * DF * DE)

Substituting the known values, we have:

cos(D) = (332 + 652 - 562) / (2 * 33 * 65)

= 59.49

Simplifying this expression gives us the value of the cosine of angle ∠D.

The composite function -3 x f(-8) +7 x g(2) has a value of 53

How to evaluate the composite function

From the question, we have the following parameters that can be used in our computation:

f(x) = 2x + 3 and g(x) = x

Calculating f(-8) and g(2), we have

f(-8) = 2 * -8 + 3 and g(2) = 2

Evaluate

f(-8) = -13 and g(2) = 2

Using the above as a guide, we have the following:

-3 x f(-8) +7 x g(2) = -3 * -13 + 7 * 2

Evaluate

-3 x f(-8) +7 x g(2) = 53

Hence, the composite function has a value of 53

Step-by-step explanation:

brad is 5 ft tall and has a shadow of 4 ft when standing by the near the trees shadow is 24 ft

so 24 ft / 4 ft =6 ft

so the tree is 6 times bigger than brad so you would multiple brads hight by 6

so that would be 5 times6 =30 ft

thus the tree is 30 ft tall

The shadow height of the tree is 24 feet, then the height of the tree will be equal to 30 feet.

The four basic mathematical operations are the addition, subtraction, multiplication, and division of two or even more integers.

Among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.

As per the given information in the question,

Answer:

64 inches cubed

The coefficient for x² in the equation x² - 5x + 6 is 1, as it is the implied coefficient when no numerical coefficient is written before a term in a polynomial.

The coefficient for x2 in the polynomial equation x2 - 5x + 6 is implied to be 1. When a term in a polynomial has no numerical coefficient written, it is understood that the coefficient is 1. In any polynomial equation of the form ax2 + bx + c = 0, the coefficient of x2 is represented by a. In the given expression, since there is no number in front of x2, a is 1. Therefore, the coefficient of x2 in the equation x2 - 5x + 6 is 1.

c=1/2(3.14)(70)

c=109.9

Sorrry if i am wrong

To find the length of the semicircular driveway with a diameter of 70 ft, calculate the circumference using the formula C = π * diameter.

To find the length of the driveway:

Given the diameter is 70 ft, the radius is half of that, which is 35 ft.

The formula for the circumference of a circle is C = π * diameter.

Substitute the values to find the length, C = 3.14 * 70 ft = 219.8 ft.

Answer:

y = -3/2x+3

Step-by-step explanation:

We first need to find the slope using

m = (y2-y1)/(x2-x1)

    = (9-0)/(-4 -2)

       9/-6

   =-3/2

We will use the slope intercept form of the equation

y = mx+b where m is the slope and b is the y intercept

y = -3/2x+b

Substitute a point into the equation

0 = -3/2(2) +b

0 = -3+b

b = 3

y = -3/2x+3

The student solved the system of equations by substitution. He substituted y = x - 1 into the first equation and solved for x. He then substituted the value of x into the second equation to find the value of y.

The correct statement could be that Vince substituted the equation y = x - 1 into the first equation -5x + y = -21. Next, he solved for x. Once he found the value for x, he substituted that into the equation y = x - 1 to find the value of y, providing the solution to the system of equations.

To find the answer of this question, we just need to multiply the probability to go bankrupt of each company. The calculation will be:

Final answer:

The maximum volume of paint required is 2 liters.

Explanation:

To calculate the maximum volume of paint needed to paint the wall, we need to first determine the area of the wall. The wall measures 2.1 m by 5.2 m, so the area is:

Area = Length × Width = 2.1 m × 5.2 m = 10.92 m²

Now, we know that one tin of paint covers 3.5 m² and contains 0.5 liters of paint. To find the number of tins needed, we divide the total area by the area covered by one tin:

Tins needed = Total area / Area per tin = 10.92 m² / 3.5 m²

Tins needed = 3.12

Since we cannot buy a fraction of a tin, we need to round up to the nearest whole number, which means Max needs 4 tins of paint. To find the total volume of paint, we multiply the number of tins by the volume of one tin:

Total volume = Tins needed × Volume per tin = 4 × 0.5 L = 2 L

Therefore, the maximum volume of paint Max will need is 2 liters.

Final answer:

The image point of the original point (9,5) after a translation right 4 units and up 4 units is (13,9).

Explanation:

The student is asking about the result of a translation transformation in a two-dimensional coordinate system. Specifically, the student wants to know the new coordinates of a point after it is moved 4 units to the right and 4 units up. The original coordinates are given as (9,5). To find the image point after the translation, we simply add the corresponding values to each coordinate. So, we add 4 to the x-coordinate (9+4) and 4 to the y-coordinate (5+4).

The new coordinates, or the image point, will be:

x-coordinate: 9 + 4 = 13

y-coordinate: 5 + 4 = 9

Therefore, the image point after the translation is (13,9).

To simplify the expression 15/1+4 + 6+3/3, we perform the division operations first, followed by addition, which results in the simplified expression of 26.

To simplify the expression 15/1+4 + 6+3/3 using the order of operations, we must follow specific rules. The order of operations is often remembered by the acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). In the absence of parentheses and exponents in this expression, we'll focus on the multiplication/division and addition/subtraction.

First, let's look at the division and multiplication. Since there's no multiplication, we only need to perform the division operations, and we proceed from left to right:

Now we are left with the addition operations:

15 + 4 + 6 + 1 = 26

Therefore, the simplified expression is 26. To generate accurate answers, always follow the order of operations diligently.

The simplified expression is [tex]\( 26 \).[/tex]

To simplify the expression using the order of operations (PEMDAS/BODMAS), we follow these steps:

2. Exponents/Orders

3. Multiplication and Division (from left to right)

4. Addition and Subtraction (from left to right)

Given the expression [tex]\( \frac{15}{1} + 4 + 6 + \frac{3}{3} \),[/tex] let's simplify it step by step:

1. Solve the division: [tex]\( \frac{15}{1} = 15 \) and \( \frac{3}{3} = 1 \).[/tex]

Answer:

x1 = 0.45 and x2 = -1.12

Step-by-step explanation:

To solve the equation 6x2+4x−3=0 using the quadratic formula, we use the following equation:

x = [-b ± √(b2 - 4ac)] / 2a

Where a, b and c are coefficients of the quadratic equantion (in our case, a = 6, b = 4 and c = -3)

So we have that:

x1 = [-4 + √(16 + 72)] / 12 = (-4 + 9.3808) / 12 = 0.4484

x2 = [-4 - √(16 + 72)] / 12 = (-4 - 9.3808) / 12 = -1.1151

Rounding to nearest hundredth, we have x1 = 0.45 and x2 = -1.12

Answer:7/87

Step-by-step explanation:

To find the probability that a country is in the South Asia region given that Shreya categorized the country's business startup costs as high, we can use conditional probability. This involves finding the intersection of the two events and dividing it by the probability of one of the events. In this case, we need the specific numbers to calculate the actual probabilities.

To find the probability that a country is in the South Asia region given that Shreya categorized the country's business startup costs as high, we need to use conditional probability. Let's assume that event A is the country being in the South Asia region and event B is the country's business startup costs being categorized as high. We can use the formula:

P(A|B) = P(A ∩ B) / P(B)

In this case, P(A ∩ B) is the probability that the country is in the South Asia region and its business startup costs are categorized as high. P(A ∩ B) refers to the intersection of A and B, meaning the countries that fall into both categories. P(B) is the probability that the business startup costs are categorized as high, which is given as part of the question.

Since we don't have the numbers needed to calculate the actual probabilities, I'll provide an example for better understanding. Let's say there are 10 countries in total, and 3 of them are in the South Asia region. Out of these 3 countries, 2 have high business startup costs. So in this case, P(A ∩ B) = 2/10 and P(B) = 6/10. Plugging these values into the formula, we have:

P(A|B) = (2/10) / (6/10) = 2/6 = 1/3

Therefore, the probability that a country is in the South Asia region given that Shreya categorized the country's business startup costs as high is 1/3.
