Answer:

a. Here is a Venn diagram to illustrate the information:

markdown

    ESUT

    /   \

 FUTO  UNN

  \    /

   \  /

 (X)

where (X) represents the number of applicants who applied to all three universities.

b. To find the number of applicants who applied to all three universities, we can use the formula:

scss

Total = ESUT + FUTO + UNN - (Exactly two) - (None) + (All three)

We know that:

makefile

ESUT = 60 + 54 + (All three)

UNN = 75 + (All three)

FUTO = 54 + 60 + (All three)

Total = 290

Substituting these values, we get:

scss

290 = (60 + 54 + All three) + (54 + 60 + All three) + (75 + All three) - (Exactly two) - (None) + (All three)

Simplifying, we get:

scss

290 = 249 + 2(All three) - (Exactly two) - (None)

We also know that:

scss

None = Total - (ESUT + FUTO + UNN) = 290 - (181 + 142 + 117) = -150

This negative value means that there are no applicants who did not apply to any of the universities. This is a contradiction, so we must have made an error in our calculations.

Therefore, we cannot find the number of applicants who applied to all three universities or exactly two universities.

Explanation:

Subtract the second equation from the first one

\(\ \ \ \ 3x+3y-5z = 4 \ \ ... \text{ eq 1}\\-(4x-4y+z = -1) \ \ ... \text{ eq 2}\\---------\\\ \ -x+7y-6z = 5\)

Let's call that result equation 4.

Now focus on equation 3 and equation 4

equation 3 is   -x+7y-6z = 2

equation 4 is   -x+7y-6z = 5

Note how the left hand sides are identical, but the right hand sides are different. This means that we have an inconsistent system with no solutions. No matter what numbers we pick for x,y,z, there is no way to make all three given original equations to be true.

Answer:

A

Step-by-step explanation:

To multiply powers of a variable, add the exponents:

\(x^m\cdot x^n = x^{m+n}\)

This rule works for all exponents, positive, negative, or zero.  Also, remember that \(x^0=1\).

Also, remember the definition of negative exponent:  \(x^{-n} = \frac{1}{x^n}\)

To multiply the two monomials, start by multiplying the coefficients, 14 and 4.  That gives 56, so your answer begins with 56.

Now for the powers of x,  \((x^3)(x^{-5}) = x^{3+(-5)} =x^{-2} = \frac{1}{x^2}\)

For the powers of y,  \((y^{-4})(y^4)=y^{4+(-4)} = y^0 = 1\)\((y^{-4})(y^4) = y^{-4+4} = y^0 =1\)

Your answer is

\(56 \cdot \frac{1}{x^2} \cdot 1 =\frac{56}{x^2}\)

What is the domain and range?

The domain and range are fundamental concepts in mathematics that are used to describe the input and output values of a function or relation.

The domain of a function refers to the set of all possible input values, or x-values, for which the function is defined.

The range of a function refers to the set of all possible output values, or y-values.

To find the domain and range of functions and represent them in different formats.

To find the domain and range of a function:

The domain refers to the set of all possible input values (x-values) for the function.

The range refers to the set of all possible output values (y-values) for the function.

To represent the function as a table, you would list the input-output pairs. For example:

Input (x) | Output (y)

-3         |        -4

-1          |         2

0         |         0

Firstly we will analyze the question statement to determine the best possible answer.

So, the statement tells us about a person named Natalie,, the owner of an App designed for teenagers. Currently, the New Mindfulness app has One thousand two hundred and sixty-two downloads. Natalie sets a target to take her App downloads to double every month.

We are expected here to provide her with the best possible exponential equation to make her achieve the set goal.

We can use two variables for our exponential equation:

y for the number of downloads.

And x for the months.

We can use any value (Whole numbers, decimals, or fractions) in our exponential equation.

Now while keeping in mind all the necessary details, we can make the exponential equation as below:

Y= 1262 (2 x b) ^ x

Where Y are the downloads

X= 1 month or 30 days

By putting the values:

Y=1262 (2) ^ 1 month

Y=2524 after one month

So, the total number of downloads will double using the above exponential equation.

The pictures below show a relationship between the number of downloads Y and the month X.

Step-by-step explanation:

Okay so to find the domain and range we need to find the x values and the y values: the domain is x and the range is y. Therefore the start of our x values can be concluded as -5 and the end is 5, so our domain will be -5 < x < 5: Note, I couldn't put the less than or equal to symbol. SO now our range is the values that are up and down, the range does down at 1 and the range is the highest at 3 so we can determine the range is 1 < y < 3. This is a continuous graph, so there is continuous x values and y values in this graph, so it's simple to use the start and the end of the domain and range followed by the possible y and x values which is represented by y and x.

Answer: 10.30

Step-by-step explanation:

Distance formula = \(\sqrt{(x_{2} +x_{1})^2+(y_{2} +y_{1})^2}\)

A (\(x_{1} ,y_{1}\)) = A(-3,-6) so \(x_{1} = -2\) and \(y_{1} =-6\)

B (\(x_{2} ,y_{2}\)) = B(-6, 1) so \(x_{2} = -6\) and \(y_{2} = 1\)

Plug in the values. You should get \(\sqrt{(-6 +-3)^2+(1 +-6)^2}=\sqrt{(-9)^2+(-5)^2}=\sqrt{81+25}=\sqrt{106}\)

The measure of arc BC is 720 times the measure of angle BAC.

Given that AC is the diameter of the circle and AB is a chord with a length of 16 units, we need to find BC (the length of the other chord) and mBC (the measure of angle BAC).

To find BC, we can use the property of chords in a circle. If two chords intersect within a circle, the products of their segments are equal. In this case, since AB = BC = 16 units, the product of their segments will be:

AB * BC = AC * CE

16 * BC = 2 * r * CE (AC is the diameter, so its length is twice the radius)

Since the area of the circle is given as 289 square units, we can find the radius (r) using the formula for the area of a circle:

Area = π * r^2

289 = π * r^2

r^2 = 289 / π

r = √(289 / π)

Now, we can substitute the known values into the equation for the product of the segments:

16 * BC = 2 * √(289 / π) * CEBC = (√(289 / π) * CE) / 8

To find mBC, we can use the properties of angles in a circle. The angle subtended by an arc at the center of a circle is double the angle subtended by the same arc at any point on the circumference. Since AC is a diameter, angle BAC is a right angle. Therefore, mBC will be half the measure of the arc BC.

mBC = 0.5 * m(arc BC)

To find the measure of the arc BC, we need to find its length. The length of an arc is determined by the ratio of the arc angle to the total angle of the circle (360 degrees). Since mBC is half the arc angle, we can write:

arc BC = (mBC / 0.5) * 360

arc BC = 720 * mBC

Therefore, the length of the arc BC equals 720 times the length of the angle BAC.

The height of of the center support that is perpendicular to the ground is 63 feet.

From the question, we are to calculate the height of the center support shown in the diagram.

In the diagram,

The perpendicular height divides the triangle into two right triangles

Thus, we can determine the height of the center support by using the Pythagorean theorem.

From the Pythagorean theorem, we can write that

65² = h² + (1/2 × 32)²

4225 = h² + (16)²

4225 = h² + 256

h² = 4225 - 256

h² = 3969

h = √3969

h = 63 feet

The total area of the floor sheet is 1020 units.

The method for finding the total area will depend on the shape(s) involved. Here are some general formulas for common shapes:

Square: To find the area of a square, multiply the length of one side by itself. For example, if the side of a square is 4 units, the area would be 4 x 4 = 16 square units.

Rectangle: To find the area of a rectangle, multiply the length by the width. For example, if a rectangle has a length of 6 units and a width of 4 units, the area would be 6 x 4 = 24 square units.

Triangle: To find the area of a triangle, multiply the base by the height and divide by 2. For example, if a triangle has a base of 5 units and a height of 8 units, the area would be (5 x 8) / 2 = 20 square units.

Circle: To find the area of a circle, multiply pi (approximately 3.14) by the radius squared. For example, if a circle has a radius of 3 units, the area would be 3.14 x 3^2 = 28.26 square units.
