The modifications did Kepler make to Copernicus’s model are planetary orbits are elliptical (A) and Earth’s rotation causes the rising and setting of the sun (E).

There are three laws, made by the Kepler, to explain the motion of the planet around the sun.

Earth’s rotation causes the rising and setting of the sun because of the earth's rotation on its axis.

Hence, the modifications did Kepler make to Copernicus’s model are planetary orbits are elliptical (A) and Earth’s rotation causes the rising and setting of the sun (E).

[tex]d = \sqrt{85}[/tex]

Step-by-step explanation:

Distance Formula: [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Simply plug in the 2 coordinates into the distance formula to find distance d:

[tex]d = \sqrt{(5-3)^2+(-1-8)^2}[/tex]

[tex]d = \sqrt{(2)^2+(-9)^2}[/tex]

[tex]d = \sqrt{4+81}[/tex]

g(x) = 2f(x)

Step-by-step explanation:

Answer: X is less than or equal to 240

The solution to the inequality 0.75x - 100 ≤ 80 is x ≤ 240.

Given is an inequality what is 0.75x – 100 ≤ 80, we need to solve it,

To solve the inequality 0.75x - 100 ≤ 80, we can follow these steps:

1. First, let's isolate the variable x by adding 100 to both sides of the inequality:

0.75x - 100 + 100 ≤ 80 + 100

0.75x ≤ 180

2. Next, we can divide both sides of the inequality by 0.75 to solve for x:

(0.75x) / 0.75 ≤ 180 / 0.75

x ≤ 240

Therefore, any value of x that is less than or equal to 240 will satisfy the inequality.

Therefore, the solution to the inequality 0.75x - 100 ≤ 80 is x ≤ 240.

Answer:

2x+2=3x-10

2+10=3x-2x

x= 12

Answer:

x = 12

Step-by-step explanation:

The diagonals PN and MO are perpendicular bisectors of each other, thus

QO = MQ , substitute values

3x - 10 = 2x + 2 ( subtract 2x from both sides )

x - 10 = 2 ( add 10 to both sides )

x = 12

Answer:

B. The function f(x) = tan(x) is an odd function because f(-x) = -f(x)

Step-by-step explanation:

The function f(x) = tan(x) is odd as  [tex]f(-x) = -f(x)[/tex]  so we can conclude the statement B. The function f(x) = tan(x) is an odd function because [tex]f(-x) = -f(x)[/tex] is the true option.

The function is a relation used to determine a value f(x) for a given x using an expression in x.

An even function is when f(x) = f(-x). It is symmetric along the y-axis.

An odd function is when f(-x) = -f(x). It is symmetric along the x-axis.

We are dealing with the function f(x) = tan(x).

We calculate f(-x) = tan(-x) = -tan(x) = -f(x).

∴ The function f(x) = tan(x) is an odd function, and odd functions are symmetric about the origin.

∴ The function f(x) = tan(x) is odd as  [tex]f(-x) = -f(x)[/tex]  so we can conclude the statement B. The function f(x) = tan(x) is an odd function because [tex]f(-x) = -f(x)[/tex] is the true option.

this is very simple actually! i can teach you:

(x,y)

so if you are counting left or right it goes to the x. for example, if you want to find J, you go to the black dot that says J and count starting from 0 or by looking at the x axis.

if you are counting up or down you go to (input the value) the y. if you want to find J for example, (the y coordinate) you go to the black dot and you count starting from 0. usually it will have the points -5 -4 -3 -2 -1 0 1 2 3 4 5 but in your problem it does not have so you just have to count carefully.

i will go search for what K' or J' means

Answer:

18.939

Step-by-step explanation:

Use SOH CAH TOA to find sin(23) = 7.4/x. Convert it to x(sin23) = 7.4. Divide both sides by sin23 to get x=18.939

Hey there!

[tex]\overline{AB} = 7.4m[/tex]

[tex]\overline{ACB} = 23°[/tex]

[tex] Sin(ACB) = \frac{\overline{AB}}{\overline{AC}}[/tex]

[tex] Sin(23°) = \frac{7.4}{\overline{AC}}[/tex]

[tex]\overline{AC}=18.939m[/tex]

The expected number of defective bolts are obtained as 175. The correct option is (C).

Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.

The probability of any event always lie in the close interval of 0 and 1 [0,1].

The zero value of probability indicates that the event will not happen while its value equal to one indicate that it will happen.

The total number of bolts tested are 24.

And, the number of defective bolts are 5.

Then, the probability of defective bolts is given as,

P(defective bolts) = 5/24

Now, the expected number of bolts can be found as,

Expected number = P(defective bolts) × Total number of bolts tested

⇒ 5/24 × 850 = 175

Hence, the expected number of bolts that will be defective is given as 175.

Answer:

48 , 132

Step-by-step explanation:

Let smaller angle = x

Larger angle = 3x - 12

x & (3x - 12) are supplementary

So, x + 3x - 12 = 180°

          4x - 12 = 180

                  4x = 180 +12

                   4x = 192

                     x = 192/4

x = 48°

Larger angle = 3*48 - 12 = 144 - 12 = 132

Answer: The measure of the smaller angle is 48,and the larger angle is 132.
