Jerome has read 50 pages of a novel. He plans to read a certain number of pages, p, each day from Monday to Friday. Which inequality shows that Jerome wants to have read at least 85 pages by the end of the day on Friday?

A. 50 + 5p ≥ 85
B. 50 + 5p ≤ 85
C. 5 (50 + p) ≥ 85
D. 5 (50 + p) ≤ 85

Answer:

C' (5, - 7 )

Step-by-step explanation:

Under a reflection in the x- axis

a point (x, y ) → (x, - y ) , thus

C(5, 7 ) → C'(5, - 7 )

The solution to the problem using laws of exponents is: \(\frac{3^{\frac{5}{12} } }{4^{\frac{1}{6} } }\)

Some of the laws of exponents are as follows:

- When multiplying by like bases, keep the same bases and add exponents.

- When you raise the base to the power of 1 to another power, keep the base and multiply by the exponent.

- If dividing by equal bases, keep the same base and subtract the denominator exponent from the numerator exponent.  

We are given the expression as:

\((\frac{3^{\frac{1}{2}} }{4^{\frac{1}{5}} }) ^{\frac{5}{6}}\)

Applying the laws of exponents gives us:

\(\frac{3^{\frac{5}{12} } }{4^{\frac{1}{6} } }\)

The solution of the equation tan²x + 7tanx + 9 = 0 on the interval -π/2 ≤ x ≤ π/2 is \(x = -\frac{\pi}{4} \quad \text{or} \quad x = -\arctan(9)\)

To solve the equation tan²x + 7tanx + 9 = 0 on the interval -π/2 ≤ x ≤ π/2, we have to factor the left side of the equation.

Let t = tanx.

Substituting this expression in the given equation, we have the following equation in t:

t² + 7t + 9 = 0

We need to solve this quadratic equation.

It can be factored as follows:(t + 1)(t + 9) = 0

So, t = -1 or t = -9.

But t = tanx, so we have tanx = -1 or tanx = -9.

We recall that on the B -π/2 ≤ x ≤ π/2, the possible values of tanx are all real numbers.

Thus, the solution of the given equation on this interval is:

\($$x = \arctan(-1) \quad \text{or} \quad x = \arctan(-9)$$\\$$x = -\frac{\pi}{4} \quad \text{or} \quad x = -\arctan(9)$$\)

So, the solution of the equation tan²x + 7tanx + 9 = 0 on the interval -π/2 ≤ x ≤ π/2 is \(x = -\frac{\pi}{4} \quad \text{or} \quad x = -\arctan(9)\)

The equation in the vertex form will be y = (x + b/2a)² - b²/4a² + c/a and the equation in the standard form will be ax² + bx + c = 0.

The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2.

Convert the standard equation into a vertex form, then we have

x² + (b/a)x + (c/a) = 0

x² + (b/a)x + b²/4a² - b²/4a² + c/a = 0

(x + b/2a)² - b²/4a² + c/a = 0

Put h = - b/2a and k = - b²/4a² + c/a, where (h, k) be the vertex of the parabola. Then the equation will be

(x - h)² + k = 0

The function written in vertex form will be y = (x - h)² + k and in the standard form will be ax² + bx + c = 0.

First find the probability of each color being drawn.

We need to find the total number of marbles first.

4 + 3 + 6 = 13

Everything will be over 13.

Probability of a white marble being drawn --> 4/13

Probability of a blue marble being drawn --> 3/13

Probability of a red marble being drawn --> 6/13

Now to find the probabilities of more than one being drawn, we can multiply.

Part A:

6/13*6/13=36/169

Part B:

3/13*3/13=9/169

Part C:

6/13*6/13=18/169

Part D:

The right triangle, like the other triangles, has three sides, three vertices, and three angles. The difference between the other triangles and the right triangle is that the right triangle has a 90  angle.

To find missing angles and sides and round to the nearest tenth, you can use different methods depending on the given information and the type of triangle or shape involved.

Some common methods include:
Trigonometric ratios (sine, cosine, tangent) for right triangles.
Angle sum property or exterior angle property for triangles.
Pythagorean theorem for right triangles.
Law of cosines and law of sines for non-right triangles.
To help find the missing angles and sides of a triangle, you need certain information about the triangle, such as known angle and side measurements, or information about the properties of the triangle.

Without this information, no concrete calculations can be made.

Provide the necessary information or describe the problem in more detail and we will help you find the missing corners and sides of the triangle and round it to tenths.

Remember to always check if any additional information is given, such as side lengths or angles ' 7 and to apply the appropriate formula or property to find the missing value.

What is linear regression?

Linear regression analysis predicts the value of one variable based on the value of another. The variable you wish to predict is referred to as the dependent variable. The variable you are using to predict the value of the other variable is known as the independent variable.

1) Give the equation of the least-squares regression line. Define any variables you use.

y = 4.133 + 3.0333x

The constant coefficient is what I used as the y-intercept.

2) Use the model from part (a) to predict the area covered by detergent at 5.5 seconds.

y = 4.133 + 3.0333(5.5)

y = 12.55015

3) The prediction made in part b) will be underestimated as the residual value will lie below 0 when x = 5.5.

Hence, the final answers are (1) y = 4.133 + 3.0333x, (2) y = 12.55015 and (3) The prediction made in part b) will be underestimated as the residual value will lie below 0 when x = 5.5.

Step-by-step explanation:

8X11=88sq

Answer:

88 units^2

Step-by-step explanation:

The area of a parallelogram can be found using he following formula:

a=b*h

where b is the base and h is the height.

We know that 11 units is the base and 8 units is the height (forms a right angle with one of the bases).

b= 11 units

h= 8 units

Substitute these values into the formula.

a= 11 units * 8 units

Multiply

a= 88 units^2

The area of the parallelogram is 88 square units.

Answer:

line A:  y = 1/2x + 8

line B:  y = -1/2x + 16

Answer:

width = 7 and length = 9

Step-by-step explanation:

Let's assume width = w, and length = 2 + w

So area of a rectangle = width * length

63 ft² = w (2 + w)

63 = 2w + w²

w² + 2w - 63 = 0

Use the quadratic formula to solve this

here, a = 1, b = 2 and c = -63

w = 7 or -9

The dimensions of a rectangle cannot be negative. So we take the dimension, w = 7.

Width = 7 and Length = 7+2 = 9

Domain = (- infinity, infinity)

Range = (- infinity, 4]

Explanation:

For a function, a vertical line drawn through the graph must not touch it twice. Looking at the graph, a vertical line will not touch the curve twice. Thus, it is a function

The domain of a function is the set of all values of x that satisfies the function. On the graph, it is between the minimum value of x on the left and the maximum value of x on the right. Looking at the graph, it extends infinitely towards the left and right side. Thus,

Domain = (- infinity, infinity)

The range of a function is the set of all values of y that satisfies the function. On the graph, it is between the minimum value of y at the bottom and the maximum value of y at the top. Looking at the graph, it extends infinitely downwards and has a maximum value of 4 at the top. Thus,

Range = (- infinity, 4]

Answer:

58°

Step-by-step explanation: Nick was able to view the museum painting through the mirror due to reflection. The painting was reflected after hitting the plane mirror. According to the law of reflection, the angle of incidence is equal to the angle of reflection. The incident angle is the angle which the incident ray( the ray which strikes or hits the plane mirror) makes with the normal(line perpendicular to the tangent).

Thus, the angle which the painting makes with the mirror is equal to the angle at which the painting is being viewed = 58°.

Step-by-step explanation:

The forecasts for periods 11 through 15 are: F11 = 297.4, F12 = 296.7, F13 = 297.1, F14 = 296.9, F15 = 297.0

Given: Smoothing constant α = 0.45, Forecast for period 10 = 297

We need to calculate the forecasts for periods 11 through 15 using the essential smoothing forecast method.

The essential smoothing forecast is given by:Ft+1 = αAt + (1 - α)

Ft

Where,

At is the actual value for period t, and Ft is the forecasted value for period t.

We have the forecast for period 10, so we can start by calculating the forecast for period 11:F11 = 0.45(297) + (1 - 0.45)F10 = 162.35 + 0.45F10

F11 = 162.35 + 0.45(297) = 297.4

For period 12:F12 = 0.45(At) + (1 - 0.45)F11F12 = 0.45(297.4) + 0.55(297) = 296.7

For period 13:F13 = 0.45(At) + (1 - 0.45)F12F13 = 0.45(296.7) + 0.55(297.4) = 297.1

For period 14:F14 = 0.45(At) + (1 - 0.45)F13F14 = 0.45(297.1) + 0.55(296.7) = 296.9

For period 15:F15 = 0.45(At) + (1 - 0.45)F14F15 = 0.45(296.9) + 0.55(297.1) = 297.0

Therefore, the forecasts for periods 11 through 15 are: F11 = 297.4, F12 = 296.7, F13 = 297.1, F14 = 296.9, F15 = 297.0 (All values rounded to two decimal places)
