Answer:

true

Step-by-step explanation:

The values of x and y are x = 375 square feet and y = 6,300 pounds

To find the values of x and y, we need to determine the ratio of lifting force to area and use it to fill in the missing values in the table.

Given:

- The ratio of lifting force to area is equivalent for all pairs in the table.

Let's calculate the ratio for the given pairs:

1. [tex]\( \frac{125}{1875} = \frac{150}{2250} = \frac{175}{2625} = \frac{250}{3750} \)[/tex]

2. [tex]\( \frac{250}{3750} = \frac{x}{5625} \)[/tex]

3. [tex]\( \frac{250}{3750} = \frac{420}{y} \)[/tex]

From the given pairs, we can observe that the ratio is [tex]\( \frac{250}{3750} \)[/tex] for all of them.

Now, using this ratio, we can find the missing values:

2. [tex]\( \frac{250}{3750} = \frac{x}{5625} \)[/tex]

[tex]\[ x = \frac{250 \times 5625}{3750} = 375 \, \text{square feet} \][/tex]

3. [tex]\( \frac{250}{3750} = \frac{420}{y} \)[/tex]

[tex]\[ y = \frac{3750 \times 420}{250} = 6300 \, \text{pounds} \][/tex]

Therefore, the correct values are:

[tex]\[ x = 375 \, \text{square feet} \][/tex]

[tex]\[ y = 6300 \, \text{pounds} \][/tex]

So, the correct answer is: [tex]\[ \text{Option D: } x = 375 \, \text{square feet} \, \text{and} \, y = 6300 \, \text{pounds} \][/tex]

x= 335 square feet and y = 7,500 pounds

x = 375 square feet and y = 6,300 pounds

Answer:

infinite solutions

Step-by-step explanation:

Distribute the left side and simplify

- 8x - 17 = - 8x + 4 - 21

- 8x - 17 = - 8x - 17

Since both sides are equal the equation has infinite solutions

what's the question????

Answer:

The function increase between 0 and 1, and from 2 to infinity.

Step-by-step explanation:

Any one variable function f(x) increases when f(x2) is greater than f(x1), where x2 is greater than x1. For example, in the plot it can be seen that for x2 = 1, f(x2) = 1 and for x1 = 0, f(x1) = 0. So, between points 0 and 1, the function increase. Also, from 2 onwards, the function increase their values.

Answer:

[tex]x= -7[/tex]

Step-by-step explanation:

We need to solve the following root equation:

[tex]\sqrt[3]{x-1} + 2 = 0[/tex]

1. First, we need to add minus two to both sides of the equation:

[tex]\sqrt[3]{x-1}= -2[/tex]

2. Elevate each side of the equation to the power of 3:

[tex]x-1= -8[/tex]

3. Solve for 'x':

[tex]x= -8 + 1[/tex]

[tex]x= -7[/tex]

Therefore, the result is:

[tex]x= -7[/tex]✔️

Answer:7

Step-by-step explanation:

There are 15 sleeping and only 8 snoring you subtract 8 from 15 which leave you with 7 and that's how many people

By subtracting the number of travelers snoring (8) from the total number of travelers (15), we determine that there are 7 travelers not snoring.

To find out how many travelers in the hostel are not snoring, we will subtract the number of travelers who are snoring from the total number of travelers. The problem states that 8 travelers are snoring, and there are 15 travelers in total. So, we perform the following calculation:

Total travelers - Travelers snoring = Travelers not snoring

15 - 8 = 7

Thus, there are 7 travelers who are not snoring.

Answer:

c = 36.87

Step-by-step explanation:

arcsin(3/5)=36.87

Answer:

The correct option is D. 81.8%

Step-by-step explanation:

Mean of the data set is given to be 40

⇒ μ = 40

Standard deviation of the data set is given to be 5

⇒ σ = 5

Now we are supposed to find out what percent of the numbers fall between 35 and 50

[tex]\implies z =\frac{x-\mu}{\sigma}[/tex]

Now for P(35 < x < 50) :

Substitute x = 35 ⇒ z = -1

Substitute x = 50 ⇒ z = 2

So, P(-1 < z < 2) = P(z < 2) - P(z < -1)

⇒ P(-1 < z < 2) = 0.9772 - 0.1587

⇒ P(-1 < z < 2) = 0.8185

⇒ P(-1 < z < 2) = 81.8%

Therefore, 81.8% percent of the numbers fall between 35 and 50

Hence, The correct option is D. 81.8%

In the finding of m<FOE, I think it would be 70°.

Answer:

∠FOE = 90°

Step-by-step explanation:

In this question given is m∠AOC = 120°, m∠BOD = 150°.

We have to calculate ∠FOE.

Since ∠AOB + ∠COD + ∠BOC = 180°  [ Angle at a point on a straight line ]

∠AOB + ∠COD = 180° - ∠BOC ---(1)

It is given ∠AOC = 120° = ∠AOB + ∠BOC -----(2)

and ∠BOD = 150° = ∠BOC + ∠COD ------(3)

By adding equation (2) and (3)

150 + 120 = ∠ BOC + ∠COD + ∠AOB + BOC

270 = 2∠BOC + ∠COD + ∠ AOB

Now from equation (1)

270 = 2∠BOC + (180 - ∠BOC)

270 = 180 + ∠BOC

270 -180 = ∠BOC

∠BOC = 90°

Since ∠ BOC ≅ ∠FOE   (opposite angles)

Therefore, ∠FOE = 90° is the answer.

Answer:

vertex = (2, - 16)

Step-by-step explanation:

given

f(x) = (x - 6)(x + 2) ← equate to zero to find the zeros

(x - 6)(x + 2) = 0

Equate each factor to zero and solve for x

x - 6 = 0 ⇒ x = 6

x + 2 = 0 ⇒ x = - 2

The vertex lies on the axis of symmetry which is situated at the midpoint of the zeros, hence

[tex]x_{vertex}[/tex] = [tex]\frac{6-2}{2}[/tex] = [tex]\frac{4}{2}[/tex] = 2

Substitute x = 2 into f(x) for corresponding y- coordinate of vertex

f(2) = (2 - 6)(2 + 2) = - 4 × 4 = - 16

vertex = (2, - 16)

Answer:

40°

Step-by-step explanation:

arc AB has twice the measure of the inscribed angle BCA that intercepts it, so we have the relation ...

(6x-50)° = 2(2x)°

2x -50 = 0

2x = 50

So, angle BCA has measure 50°. Since AC is a diameter, angles BCA and BAC are complementary. Thus ...

m∠BAC = 90° - m∠BCA = 90° - 50°

m∠BAC = 40°

Answer:

7

Step-by-step explanation:

Replace both instances of x in f(x) = 2x + 9 with -1:

f(-1) = 2(-1) + 9 = 7

Thus, f(-1) = 7

The value of the function f(x) = 2x + 9 at x = - 1 Or f(-1) is 7.

A function can be defined as the outputs for a given set of inputs.

The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

Given, A function f(x) = 2x + 9.

We know, Substitution in mathematics is when we replace some specific numerical values to variables according to our wants or given in the problem.

Therefore, f(-1) = 2(-1) + 9.

f(-1) = - 2 + 9.

f(-1) = 7.
