A trapezoid has an area of 24 square meters. The length of the bases of the trapezoid are 5 meters and 7 meters. What is the height of the trapezoid?

Answers

As with any formula, fill in the values you know and solve for the one you don't know.

A = (b1 +b2)/2*h
24 m^2 = (5 m +7 m)/2 * h
24 m^2 = (6 m) * h
(24 m^2)/(6 m) = h
4 m = h

The height of the trapezoid is 4 meters.

A navigator plots the course a plane is currently traveling. The plane is 300 miles from its destination. If it continues on its current course it will travel 325 miles and end up 125 miles due south of its destination. To the nearest degree, how many degrees is the plane off course?

Answers

We have to use the rule of cosx° to solve this problem. Attached is a diagram of the navigator's course for the plane. It is similar to the shape of a triangle. We know the plane is 300 miles from its destination, so that will be one of the sides. On the current course, it is 325 miles from its destination, so that will be another one of the sides. The last side is 125 because that is the distance between the destination and the anticipated arrival. Cosx° is what we are looking for.

To find how many degrees off course the plane is, we must use the rules of Cosx°, which is shown in the attached image.

The plane is approximately 23° off course.

Final answer:

The plane in question is approximately 23 degrees off course. This calculation is derived from the tangent function in trigonometry based on the distances given.

Explanation:

From the question, we understand that the plane is creating a right triangle due to its off-course direction. Using the Pythagorean theorem, the length of the hypotenuse, or the distance that the plane will travel, is 325 miles. The difference between the direct route (300 miles) and the off-course southern distance (125 miles) forms the two other sides of the triangle.

However, we're looking for the angle, not the sides. This is where trigonometry comes in. Specifically, the tangent function will be valuable here as it involves the opposite and adjacent sides of a right triangle (the off-course southern distance and the direct route distance). If we let the 'off-course' angle be θ, then we have:

Tan(θ) = (distance south / direct distance) = (125 miles / 300 miles)

In order to find the angle θ from this equation, we'll need to use the inverse tangent function.

θ = atan(125/300) = 22.61986495 degrees.

Therefore, to the nearest degree, the plane is approximately 23 degrees off course.

which translation maps the graph of the function f(x)=x^2 onto the function g(x)=x^2-6x+6

Answers

write x²-6x+6 into vertex form by completing a perfect square:
x²-6x+9+6-9=(x-3)²-3
compared with f(x)=x², g(x)=(x-3)²-3 is shifted three units to the right and three units down.

Answer:

Translation from (0,0) to (3,-3), 3 units down, and 3 units to the right.

Step-by-step explanation:

The Geometric Transformation called Translation of this parabola f(x)=x² is obtained, firstly by shifting it down 3 units simply adding -3 units as the independent term.

The Translation of the Parabola is counted by its vertex. y=x² (0,0) to y=x²-6x+6 (3,-3).

Algebraically:

So, f(x)=x² -3

Looking at g(x)=x²-6x+6, we still need to make it down after the curve intercept y-axis. b<0

Then, let's shift it three units to the right so its vertex hit the point 6, as y-coordinate, we have to add -3. If we want to add to the right sum negative value, then square it:

y= (x-3)²-3

y=x²-6x+9-3

y=x²-6x+6

if f(x)= 2x^2+5sqrt(x-2), complete the following statement: The domain for f(x) is all real numbers _____ than or equal to 2. (fill in the blank)

Answers

Answer:

Greater.

Step-by-step explanation:

The in the function [tex]f(x)=2x^2+5\sqrt{x-2}[/tex], the square root term [tex]\sqrt{x-2}[/tex] has to give a real number if [tex]f(x)[/tex] is to be real. This can only happen if [tex]x\geq 2[/tex] because if [tex]x<2[/tex] then [tex]\sqrt{x-2}[/tex] will give a complex number and therefore [tex]f(x)[/tex] will not be real.

Thus, the domain for f(x) is all real numbers greater than or equal to 2.

The domain for f(x) is all real numbers greater than or equal to 2.

This is because the square root function is undefined when its argument is less than or equal to 0. So, the expression 5sqrt(x-2) is defined only when x-2 is greater than or equal to 0. This means that x must be greater than or equal to 2.

The domain of f(x) is all real numbers x such that x ≥ 2.

Here is a table that shows the values of f(x) for different values of x:

x | f(x)

2 | 20

3 | 29

4 | 42

5 | 57

6 | 74

As you can see, the values of f(x) are defined for all real numbers x such that x ≥ 2.

We can find the average daily balance of Victor's credit card by using a proportion. Proportions may be used to find missing values in times when we have percentages. The proportion compares two fractions and both sides equal the same amount (that's how we'll know we got the correct answer). The proportion will be written as such: [tex] \frac{is}{of} [/tex] = [tex] \frac{percent}{100} [/tex] . To fill in the blanks, we know our "is" is 37. That is the part of the whole that we are looking for, the "of". Our percent is 2.9, and that goes over 100. To solve. we cross multiply 100 x 37, which gives us 3700. Last, we divide by 2.9. After dividing our final answer is 1,275.86. This means that Victor's average daily balance is is $1,275.86.

I took the test and please mark brainly

AND PLEASE SCROLL DOWN WHENEVER YOUR LOOKING FOR ANSWERS BECAUSE THERE'S A REASON IT SOMETIMES SAYS 2 ANSWERS and if you see this please copy and paste this because some people are to lazy to scroll down and do work

Final answer:

For Amo, the median (89) is higher than the mean (84.6), and for Javier, the mean (77.4) is higher than the median (68). Thus, Mr. Malloy should use the median for Amo and the mean for Javier for the best possible grades.

Explanation:

To determine the best possible grade for both Amo and Javier, we first need to calculate their mean and median scores. The mean is calculated by adding all the test scores together and dividing by the number of tests. The median is the middle score when all scores are listed in ascending order. If there is an even number of scores, the median is the average of the two middle scores.

Amo's Scores: 97, 92, 89, 55, 90
Javier's Scores: 68, 97, 65, 92, 65

For Amo, we calculate the mean as follows:
(97 + 92 + 89 + 55 + 90) / 5 = 84.6

The median for Amo would be the third score since there are five tests, which is 89.

For Javier, we calculate the mean as follows:
(68 + 97 + 65 + 92 + 65) / 5 = 77.4

The median for Javier would also be the third score, which is 68.

Now, comparing Amo's mean and median, we see that the median (89) of Amo's test scores is higher than the mean (84.6). Therefore, for Amo, Mr. Malloy should use the median.

Looking at Javier's mean and median, we see that the mean (77.4) of Javier's test scores is higher than the median (68). So, for Javier, Mr. Malloy should use the mean.

The teacher should use the median for Amo and the mean for Javier for the best possible grade.

Quadrilateral ACEG≅Quadrilateral NMRP Which statement is true?
A:
EG≅MN
B:AC≅MR
C: AG≅NP
D:CE≅NP
pls help

Answers

Final answer:

The true statement given that quadrilateral ACEG is congruent to quadrilateral NMRP is D: CE≡NP, which matches the corresponding sides based on the order of the vertices in the name of each quadrilateral following CPCTC.

Explanation:

If quadrilateral ACEG is congruent to quadrilateral NMRP, then corresponding parts of congruent polygons are congruent as well. This principle is often abbreviated as CPCTC (Corresponding Parts of Congruent Triangles are Congruent). Applying this rule, we need to match each vertex of quadrilateral ACEG to the corresponding vertex of quadrilateral NMRP.

To determine which statement is true, we need to compare the corresponding parts:

EG≡MN: This would be true if G corresponded to N and E to M, which would make EG and MN opposite sides.AC≡MR: This would imply that A corresponds to M and C to R, which are not opposite each other based on the naming of the quadrilaterals. This is not correct.AG≡NP: For this to be true, A would have to correspond to N and G to P. But again, A and G are not opposite vertices so this can't be true.CE≡NP: If C corresponds to N and E corresponds to P, then CE and NP would be equivalent and therefore congruent. Since there are four sides, the connecting letter should signify that C corresponds to N, and E to P, making this the correct correspondence.

Hence, the correct statement based on the information given and the application of CPCTC is D: CE≡NP.
