Answer:

Step-by-step explanation:

Calculate the distance (d) using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (2, 8) and (x₂, y₂ ) = (- 1, 9)

d = $\sqrt{(-1-2)^2+(9-8)^2}$ = $\sqrt{(-3)^2+1^2}$ = $\sqrt{9+1}$ = $\sqrt{10}$ → C

Answer:

$\sqrt{10}$

Step-by-step explanation:

Using the distance formula:

$\sqrt{(x_b - x_a)^2 + (y_a - y_b)^2}$

Plugging the numbers in:

$\sqrt{(-1-2)^2 + (9 - 8)^2 }$

Simplify:

$\sqrt{9 + 1}$

Answer:

$\sqrt{10}$

A farmhouse shelters 10 animals. Some are pigs and sone are ducks. Altogether there are 36 legs. How many of each animal are the

german

8 pigs x 4 legs each = 32. so you need 2 ducks to give you 10 animals total. So 32 + 2 ducks with 2 legs = 36.

There are 8 pigs and 2 ducks.

What is the smallest positive degree angle measure equivalent to sin^-1 (0.391)?

natta225 [31]

Given:

The value is:

$\sin^{-1}(0.391)$

To find:

The smallest positive degree angle measure equivalent to $\sin^{-1}(0.391)$ .

Solution:

We have,

$\sin^{-1}(0.391)$

Using the scientific calculator, we get

$\sin^{-1}(0.391)=23.0167366398^\circ$

$\sin^{-1}(0.391)\approx 23^\circ$

Therefore, the smallest positive degree angle measure equivalent to $\sin^{-1}(0.391)$ is 23 degrees.

(5 points) An urn contains two blue balls denoted by B1 and B2, and three white balls denoted by W1, W2 and W3. One ball is draw

never [62]

Answer:

The probability of the event that first ball that is drawn is blue is $\frac 25$ .

Step-by-step explanation:

Probability:

If S is is an sample space in which all outcomes are equally likely and E is an event in S, then the probability of E,denoted P(E) is

$P(E)=\frac{\textrm{The number of outcomes E}}{\textrm{The total number outcomes of S}}$

Given that,

An urn contains two balls B₁ and B₂ which are blue in color and W₁,W₂ and W₃ which are white in color.

Total number of ball =(2+3) =5

The number ways of selection 2 ball out of 5 ball is

=5²

=25

Total outcomes = 25

List of all outcomes in the event that the first ball that is drawn is blue are

B₁B₁ , B₁B₂ , B₁W₁ , B₁W₂ , B₁W₃ , B₂B₁ , B₂B₂ , B₂W₁ , B₂W₂ , B₂W₃

The number of event that the first ball that is drawn is blue is

=10.

The probability of the event that first ball that is drawn is blue is

$=\frac{10}{25}$

$=\frac25$

How do I find the missing angle?

Sveta_85 [38]

To find the missing angle first we need to fill in the other angles.
If we look at the 128 its on a straight line that is separated by another straight line so to get the angle on the other side of the line we need to subtract 128 from 180 which is 52.
The same goes for 160 so 180-160 = 20
And again the same for 60 so 180-60 = 120
So now that we have 2 out of 3 angles in the triangle we can figure out the final one by subtracting 120 and 20 from 180 (because theres 180 degrees in a triangle) which equals 40
Now if we look at the 40 degrees the other side is its opposite which makes it the same degree, and now we once again have 2 out of the 3 angles in a triangle so go to the triangle with 52 degrees and 40 degrees and subtract them from 180 which would be 88 degrees.
Now we subtract 88 from 180 to get the missing angle that we need (because its on another straight line thats been separated by another straight line) which equals 92

So the answer to your question is 92 degrees
