Answer:

[tex]x=\frac{5\pi}{4}[/tex]

Step-by-step explanation:

We want to solve;

[tex]\cscx=-\sqrt{2}[/tex] in the 3rd quadrant

Recall that;

[tex]\sin x=\frac{1}{\csc x}[/tex]

We use the reciprocal ratio to get;

[tex]\sin x=-\frac{\sqrt{2}}{2}[/tex]

In the third quadrant the solution is

[tex]x=\pi+\sin^{-1}(\frac{\sqrt{2} }{2} )[/tex]

The stilts increase a persons heart by 1.5 yards.If Bonnie who is 5 feet and 7 inches tall walks on stilts how tall will be.

Answers

Bonnie will be 10 feet and 1inch. Because 1.5 yards is actually 4.5 feet, since 3 feet make up 1 yard. 5 feet + 4 feet= 9 feet. 7 inches plus 6 inches(which is half a foot) = 13 inches or 1 foot and 1inch. 9 feet + 1 foot and 1 inch = 10 feet and 1 inch.

Answer:

[tex]\boxed{\text{10 ft 1 in}}[/tex]

Step-by-step explanation:

1. Convert the height of stilts to inches

1.5 yd × (36 in/1 yd) = 54 in

2. Convert Bonnie's height to inches

5ft 7in = 5 ft × (12 in/1 ft) + 7 in = 60 in + 7 in = 67 in

3. Calculate Bonnie's height on stilts

67 in + 54 in = 121 in

4. Convert inches back to feet and inches

121 in × (1 ft/12 in) = 10R1 ft = 10 ft 1 in  

Bonnie will be [tex]\boxed{\text{10 ft 1 in}}[/tex] tall on stilts.

[tex]( \frac{3}{34} , \frac{501}{34} )[/tex]

EXPLANATION

The given parabola has equation;

[tex]y = 34 {x}^{2} - 6x + 15[/tex]

Comparing this equation to

[tex]y = a{x}^{2} + bx + c[/tex]

we have

a=34, b=-6 and c=15

The x-coordinate of the vertex is given by:

[tex]x = \frac{ - b}{2a} [/tex]

[tex]x = \frac{ - - 6}{2(34)} [/tex]

[tex]x = \frac{ 6}{2(34)} [/tex]

[tex]x = \frac{ 3}{34} [/tex]

The y-coordinates of the vertex is obtained by substituting the x-value of the vertex into the equation:

[tex]y = 34( { \frac{3}{34} })^{2} - 6( \frac{3}{34}) + 15[/tex]

What is a Cone?

A cone is a three-dimensional shape in geometry that narrows smoothly from a flat base (usually circular base) to a point(which forms an axis to the center of base) called the apex or vertex.

The volume of a cone is given by the equation

Volume of Cone = ( 1/3 ) πr²h

where r is the radius of the cone

h is the height of the cone

Surface area of the cone = πr ( l + r )

where l = √ ( b² + r² )

Given data ,

Let the radius of the cone be r = 5 units

Let the height of the cone be h = 9 units

And , Volume of Cone = ( 1/3 ) πr²h

On simplifying , we get

V = ( 1/3 ) ( 3.14 ) ( 5 )² ( h )

V = 1.0467 x 25 x 9

Julio and his family ordered 6 pizzas for dinner. His parents ate 3/7 of one pizza, Julio's brothers ate 2 3/4 pizzas and his sisters ate 2 1/2 pizzas. How much pizza was left for Julio to eat?

Answers

approximately 0.3 or 3/10 pizza was left for Julio to eat.

mind you some numbers were rounded. if you want the exact number then it's 9/28 which is equal to 0.32.

hope this helps

Final answer:

After accounting for the amounts of pizza eaten by Julio's family (parents, brothers, and sisters), you find that there was approximately 0.36 pizzas left for Julio to eat.

Explanation:

This question deals with some basic arithmetic and fractions. Start by counting how many pizzas Julio's family ate altogether. His parents ate 3/7 of one pizza, his brothers ate 2 3/4 pizzas, and his sisters ate 2 1/2 pizzas.

To add these amounts together, you might find it easiest to convert all the fractions to sevenths. The brothers ate 2 4/7 pizzas (as 4/7 is equivalent to 1/2) and the sisters ate 2 3.5/7 pizzas (as 3.5/7 is equivalent to 1/2). Add these to the 3/7 pizza the parents ate, you find the family ate a total of approximately 5.64 pizzas.

Since Julio's family ordered 6 pizzas in total, you then subtract the total amount eaten by the family from 6, which is approximately 0.36 pizzas. Therefore, Julio was left with 0.36 pizzas to eat.

Classify each conic section and write its equations in standard form. Show work.

[tex]4x^2+2y^2-8x+16y-52=0[/tex]

Answers

Answer:

The conic is ellipse of equation (x - 1)²/22 + (y + 4)²/44 = 1

Step-by-step explanation:

* Lets revise how to identify the type of the conic  

- Rewrite the equation in the general form,  

 Ax² + Bxy + Cy² + Dx + Ey + F = 0  

- Identify the values of A and C from the general form.  

- If A and C are nonzero, have the same sign, and are not equal  

 to each other, then the graph is an ellipse.  

- If A and C are equal and nonzero and have the same sign, then  

 the graph is a circle  

- If A and C are nonzero and have opposite signs, and are not equal  

then the graph is a hyperbola.  

- If either A or C is zero, then the graph is a parabola  

* Now lets solve the problem

The equation is 4x² + 2y² - 8x + 16y - 52 = 0

∴ A = 4 and C = 2 ⇒ same sign and different values

∴ The equation is ellipse

* The standard form of the ellipse is

  (x - h)²/a² + (y - k)²/b² = 1

- Lets try to make this form from the general form

- Group terms that contain the same variable, and move the

  constant to the opposite side of the equation

∴ (4x² - 8x) + (2y² + 16y) = 52

- Factorize the coefficients of the squared terms

∴ 4(x² - 2x) + 2(y² + 8y) = 52

- Complete the square for x and y

# To make completing square

- Divide the coefficient  of x (or y) by 2 and then square the answer

- Add and subtract this square number and form the bracket of

 the completing the square

# 2 ÷ 2 = 1 ⇒ (1)² = 1 ⇒ add and subtract 1

∴ 4[(x² - 2x + 1) - 1] = 4(x² - 2x + 1) - 4

- Rewrite as perfect squares ⇒ 4(x -1)² - 4

# 8 ÷ 2 = 4 ⇒ (4)² = 16 ⇒ add and subtract 16

∴ 2[(y² + 8y + 16) - 16] = 2(y² + 8y + 16)² - 32

- Rewrite as perfect squares ⇒ 2(y + 4)² - 32

∴ 4(x - 1)² - 4 + 2(y + 4)² - 32 = 52

∴ 4(x - 1)² - 4 + 2(y + 4)² = 32 + 4 + 52

∴ 4(x - 1)² + 2(y + 4)² = 88 ⇒ divide all terms by 88

∴ (x - 1)²/22 + (y + 4)²/44 = 1

What can you say about the end behavior of the function [tex]f(x) = log_{10} (5x-1)[/tex]?

A. One end decreased and one end approaches a constant
B. One end increase and one end decreases
C. Both ends increase
D. Both ends decrease

Answers

Final answer:

For the given logarithmic function, it is undefined as x approaches negative infinity, and increases without bound as x approaches positive infinity. The correct answer is B. One end increases and one end decreases.

Explanation:

The function [tex]f(x) = log_{10} (5x-1)[/tex] is a logarithmic function with a base of 10. Its end behavior is determined by the properties of logarithmic functions.

Logarithmic functions have one side that increases without bound (to positive infinity) and one side that approaches a certain limit, but never reaches it, hence getting infinitely close to it. In this case, as x approaches negative infinity, the function becomes undefined as (5x-1) becomes a negative number and logarithm is undefined for negative values. On the other end, as x approaches positive infinity, the function will also approach positive infinity because the log of a large number gets larger.

Thus, the correct answer would be B. One end increases and one end decreases (becomes undefined).

Final answer:

The end behavior of the function is that A. one end decreases and one end approaches a constant.

Explanation:

The given function is f(x) = log10 (5x-1).

To determine the end behavior of the function, we can consider the limit of the function as x approaches positive and negative infinity.

As x approaches positive infinity, the argument of the logarithm, 5x-1, will become larger and larger, resulting in a logarithm that approaches positive infinity. Therefore, the right end of the graph increases.

Similarly, as x approaches negative infinity, the argument of the logarithm will become smaller and smaller, resulting in a logarithm that approaches negative infinity. Therefore, the left end of the graph decreases.

Thus, the correct answer is A. One end decreases and one end approaches a constant.

Given the scale drawing of a one bedroom apartment, what is the actual area of the bedroom?
A) 27 ft2
B) 54 ft2
C) 96 ft2
D) 108 ft2

Answers

Answer: Option D.

Step-by-step explanation:

You can  observe that the dimensions of the bedroom in the scale drawing are:

[tex]length=2"\\width=1.5"[/tex]

You know that [tex]\frac{1}{2}"=3feet[/tex]

Then you need to convert these dimensions to the actual dimensions. So, you get:

[tex]actual\ lenght=\frac{(2")(3ft)}{\frac{1}{2}" }=12ft\\\\actual\ width=\frac{(1.5")(3ft)}{\frac{1}{2}" }=9ft[/tex]

Therefore, you can calculate the actual area of the bedroom. This is:

[tex]Area=(actual\ lenght)(actual\ width)\\Area=(12ft)(9ft)\\Area=108ft^2[/tex]

Answer:

Option D.

Step-by-step explanation:

From the given figure it is clear that

Length of the bedroom in scale drawing = 2''

Width of the bedroom in scale drawing = 1.5''

It is given that

Scale [tex]\frac{1}{2}''=3feet[/tex]

[tex]1''=6feet[/tex]

Using this conversion we get

[tex]2''=12feet[/tex]

[tex]1.5''=9feet[/tex]

Actual length of the bedroom = 12 feet

Actual width of the bedroom = 9 feet

Area of a rectangle is

[tex]Area=length\times width[/tex]

Actual area of the bedroom is

[tex]Area=12\times 9[/tex]

[tex]Area=108[/tex]

The actual area of the bedroom is 108 ft2.

Therefore, the correct option is D.

Determine if (-2,6) and (4,12) are solutions to the system of equations:

y = x + 8
2y = x2 + 8

A) Both are solutions.
B) Neither is a solution.
C) It cannot be determined
D) Only (-2,6) is a solution.

Answers

The given points (-2,6) and (4,12) are the solution of the given equations. Option A is correct.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Given a system of equations,
y = x + 8  - - - - (1)

2y = x² + 8 - - - (2)

In order to determine that the points (-2,6) and (4,12) both are solutions of the given system of equations we must put the points in the equations,
So,
Put (-2, 6) in both equations,

Equation 1
put x = -2,
y = -2 + 8
y = 6

Equation 2
2y = [-2]² + 8
y = 4 + 8 / 2
y = 6

So points (-2, 6) is the solution of the given system of equation,

Similarly, by assigning the other point in the equation gives the same solutions

Thus, the given points (-2,6) and (4,12) are the solution of the given equations. Option A is correct.

Write the sentence as a conditional statement. Two parallel lines lie in the same plane. If two lines are parallel, then the lines lie in the same plane. If two lines lie in the same plane, then the lines are parallel.

Answers

Answer:

The conditional statement is:

If two lines are parallel then they lie in the same plane.Step-by-step explanation:

We know that a conditional statement is the statement which is written in the form of:

        If  p then q  i.e.  p → q

where p is the hypothesis of the statement.

and q is the conclusion  of the statement which is based on the hypothesis.

Here we are given a statement as:

 Two parallel lines lie in the same plane.

i.e. the hypothesis of the conditional statement is:

Two lines are parallel.

and conclusion is: They will lie in the same plane

( Because if two lines lie in the same plane then we can't conclude that they will be parallel )

At each point (x,y) on the curve the slope is 2x+3 the curve passes through the point (-3,0)

Answers

Answer:

The equation of the curve is y = x² + 3x

Step-by-step explanation:

I get your drift, but wish you had stated specifically that you wanted to find the equation of this curve.

Slope of tangent line to curve is dy/dx = 2x + 3.

Integrating that with respect to x yields y = x² + 3x + C.

The point (-3, 0) must satisfy this equation:

0 = (-3)² + 3(-3) + C, so C = 0.

The equation of the curve is y = x² + 3x

The equation of the curve where the slope at any point is 2x + 3 and it passes through the point (-3, 0) is y = x² + 3x.

The student's question involves finding the equation of a curve given that at each point (x, y) on the curve, the slope is 2x + 3, and the curve passes through the point (-3, 0). This is a problem that involves differential equations, as it asks us to find a function y(x) whose derivative with respect to x is given.

To find the equation of the curve, we integrate the slope function. Since the slope at any point is 2x + 3, we have:
∂y/∂x = 2x + 3
Integrating both sides with respect to x gives:
y = x² + 3x + C

To find the constant of integration C, we use the fact that the curve passes through (-3, 0). Substituting these values into the equation gives:
0 = (-3)² + 3(-3) + C
0 = 9 - 9 + C
Thus, C = 0, and the equation of the curve is:
y = x² + 3x.
