which are rational numbers 3,5,1,9,4,8

Answer:

A quadratic inequality is an equation of second degree that uses an inequality sign instead of an equal sign. The solutions to quadratic inequality always give the two roots. The nature of the roots may differ and can be determined by discriminant (b2 – 4ac).

Answer:

a=10

Step-by-step explanation:

Step 1: Add 54 to both sides.

9a−54+54=36+54

9a=90

Step 2: Divide both sides by 9.

9a\9 =90\9

a=10

Answer:

a=10

Step-by-step explanation:

Add 54 to both sides. You get 9a=90. Divide both sides by 9 and you get a=10.

Answer:

15 ounces

Step-by-step explanation:

0.75 tons is equal to 0.75 * 2000, or 1500, pounds (1 ton is 2000 pounds). Let x represent the number of ounces of fertilizer that should be applied. Set up a proportion:

[tex] \ \frac{1}{100} = \frac{x}{1500} [/tex]

Solving this for x, we have x = 15. So the landscaper should apply 15 ounces of fertilizer.

This is a list of trigonometric functions with the same maximum value:

(A) y = arcsinx and y = cos x

The trigonometric functions in mathematics are real functions that connect the right-angled triangle's angle to the ratios of its two side lengths.

They are extensively employed in all fields of geometry-related study, including geodesy, solid mechanics, celestial mechanics, and many others.

There are six popular trigonometric functions for an angle.

Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms (csc).

So, the following equations give us the following maximum values:

arcsinx = -1 to 1

arccosx = -1 to 1

arctanx = -pi/2 to pi/2

arcsecx = ∞

Arcsinx and Arccosx are trigonometric functions that have the same maximum value.

Therefore, this is a list of trigonometric functions with the same maximum value:

(A) y = arcsinx and y = cos x

Answer:

8750

Explanation:

There are 5/5 math teachers in the university. 3/5 of them did not want to become math teachers which means 2/5 of the math teachers is equal to 3500.

3500=2/5

divide 3500 by 2 to get 1/5 of the math teachers.

3550/2=1750

1750 is 1/5 of the math teachers.

multiply 1750 by 5 to get 5/5 of the math teachers

1750*5= 8750

Based on the data in two-way frequency table, "being in high school" and "gpa above 3.0" are not independent events.

The conditional probability is the happening of an event, when the probability of occurring of other event is given.

A two-way frequency table shows grades for students in college and students in high school.

Let H represent being in high school and G represent the GPA above 3.0. To be an independent event, they must be,

[tex]P(H|G)=P(H)[/tex]

The conditional probability of event H, given that the G is occurred, can be calculated as,

[tex]P(H|G)=\dfrac{14}{40}\\P(H|G)=0.35[/tex]

Total students below 3.0 GPA are 60 and the total number of student are 100. Thus, the probability of being in high school is

[tex]P(H)=\dfrac{60}{100}\\P(H)=0.6[/tex]

Here, conditional probability [tex]P(H|G)[/tex] is not equal to the probability of being in high school.

Hence, based on the data in two-way frequency table, "being in high school" and "gpa above 3.0" are not independent events.

k = 6

Step-by-step explanation:

given x = - 2 is a root then substitute x = 2 into the equation

(- 2)² + 5(- 2) + k = 0

4 - 10 + k = 0

- 6 + k = 0 ( add 6 to both sides )

k = 6

Answer:

k = 6

Step-by-step explanation:

since x = - 2 put x = 2 into the equation

(- 2)² + 5(- 2) + k = 0

4 - 10 + k = 0

-6 + k = 0

Answer:

See below.

Step-by-step explanation:

Hi there!

We are given a circle, and inside that circle, we know that the radius of that circle is 4 inches

We want to find the circumference of the circle.

The circumference (C) is essentially the perimeter of a circle; the formula for the circumference of a circle is 2πr (r is the radius, π is pi)

Since we know the radius, we can substitute that value into the formula

C=2πr, r=4

C=2π*4

C=8π

If you need the answer in terms of pi, then the answer is 8π inches. However, if you need a number, then substitute an approximation for π, which will usually be 3.14 or 22/7

Using 3.14 for example,

C=8*3.14=25.12 inches

Using 22/7 meanwhile,

C=8*22/7=25.14 inches  (rounded to the nearest hundredth)

So the answer is either 8π inches, 25.12 inches, or 25.14 inches (depending on how you need it approximated)

Either way, hope this helps!

Answer:

Apple Cider is the better deal.

Step-by-step explanation:

1 gallon is 128 ounces.

8 times 4.23 is 33.84. So each purchase is 33.84 ounces. If you multiply 33.84  ounces by 4 you get 135.36. (I did 4 because 3 would be too little to make a gallon).

After that you need to multiply 2.39 and 4. You need to do this because it will tell you the cost. That will come out to 9.56$.

So, that is why the apple cider is a better deal, because it is 7$ and the other would be 9.56$.

Answer:

Solve for x = 17

Solve for y = 9

The value of x and y from the figure are 17 and 7 respectively

From the given diagram, we are told that  I ll m, hence:

Get the value of x

5x-3x = -4 + 38

2x = 34

x = 34/2

x = 17

Also from the triangle:

7y - 20 + 5x - 38 = 90

7y + 5x -58 = 90

7y + 5(17) = 90 + 58

7y + 85= 148

7y = 148 - 85

7y = 63

y = 63/7

y = 9

Hence the value of x and y from the figure are 17 and 7 respectively
