Answer:

We conclude that:

cosecant (U) = 13/12

Step-by-step explanation:

Given the right-angled triangle ΔUWV, it is clear that

The opposite of angle ∠U = 24The hypotenuse = 26

Using the trigonometric ratio, we know that

sin Ф = opposite / hypotenuse

cosecant Ф = 1/ sin Ф

Thus,

cosecant Ф = hypotenuse / opposite

substituting Ф = U,  hypotenuse = 26 and opposite = 24

cosecant (U) = 26 / 24

cosecant (U) = 13/12

Therefore, we conclude that:

cosecant (U) = 13/12

The sum of all the solutions of the equation (6x+k)(3x-11)=0 is 1. Find K

BRANLIEST PLUS 20 POINTS

Answers

Answer:

16

Step-by-step explanation:

6x+k = 0

x = -k/6

3x-11 = 0

x = 11/3

-k/6 + 11/3 = 1

k - 22 = -6

k = 16

The value of k is "8".

Find K:

[tex](6x+k)(3x-11)=0\ \ is \ \ 1 \\\\K=?[/tex]

[tex]\to (6x+k)(3x-11)=0 \ \ is \ \ 1 \\\\\to (6x+k)=0\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ and \ \ \ \ \ \ \ \ \ \ \ \ \ \ (3x-11)=0\\\\\to 6x=-k\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ and \ \ \ \ \ \ \ \ \ \ \ \ \ \ 3x=11\\\\\to x=-\frac{k}{6}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ and \ \ \ \ \ \ \ \ \ \ \ \ \ \ x=\frac{11}{3}\\\\[/tex]

[tex]\to - \frac{k}{6}+ \frac{11}{3}=1\\\\\to \frac{-2k+ 22}{6}=1\\\\\to -2k+ 22=6\\\\\to -2k =6-22\\\\\to -2k =-16\\\\\to k=\frac{16}{2}\\\\\to k=8[/tex]

Therefore, the final value of k is "8".

Answer:

The center is 4 because 4 is the value in the middle when all of the values are ordered from least to greatest.

Step-by-step explanation:

The center point lies in the middle of the data. This is the point where the midpoint of data set is located. In the given dot plot the data is in descending order and when the data is observed the middle value is 4. The middle value can be between 4 and 5 in case if the data set was observed according to class preference and frequency would have been given separately.

Can someone help me with this and can you also do the work to it that would be nice (:

Answers

Answer:

its 0.5

Step-by-step explanation:

just subtract 2.1 and 1.6

a = 0.5
You have to bring the +16 over to the other side of 2.1 and turn the positive sign (+) into a negative (-)ex: 2.1 - 1.6
Now you have to subtract 1.6 from 2.1
So write:
2.1 - 1.6
a = 0.5

The equation 3x + 2 = 29 is modeled below.
Which is the first step in solving the equation for x?

Answers

Answer:

Subtract 2 from both sides.

Step-by-step explanation:

Remember to do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

> Also, note the equal sign, what you do to one side, you do to the other side of the equation.

First step is to subtract 2 from both sides of the equation:

3x + 2 (-2) = 29 (-2)

3x = 29 - 2

3x = 27

The second step is to divide 3 from both sides of the equation:

(3x)/3 = (27)/3

x = 27/3

x = 9

~

Answer:

The first step is subtracting the two on both sides.

Step-by-step explanation:

You arent exactly following PEMDAS in this equation, but you are still in a way. Before going on to x you need to go on to the numbers first. 3x would be equal to 27.

usebthe elimination method to solve the following system of equations
4x+y=13
5x-y=5​

Answers

Answer:

x = -2, y = 21

Step-by-step explanation:

Let 4x + y = 13 to be equation1 {eqn1}

and let 5x - y = 5 to be equation2 {eqn2}

Using elimination method, you would try to make sure a particular unknown has the same value in both equation 1 and 2. This would make it easy for you to subtract one equation from the other.

Notice how the value of y is the same in both equations. That's a good sign.

But the signs aren't the same. Meaning y in eqn1 has a value of +1, and y in eqn2 has a value of -1. We need to make them similar.

So, we multiply the value of y in eqn1 by all the terms in eqn2. And, do pretty much the same thing by multiplying the value of y in eqn2 by all the terms in eqn1.

You would have:

-1 * (4x + y = 13)

+1 * (5x - y = 5)

This would result in;

-4x -  y = -13 (eqn3)

5x - y = 5 (eqn4)

So, just subtract eqn3 from 4

You would have;

(5x - -4x) + (-y -- y) = (-13 - 5)

9x + 0 = -18

x = -18/9 = -2

and to find y;

just substitute the value of x into any of the 4 equations. let's try equation 1

Therefore;

4(-2) + y = 13

-8 + y = 13

y = 13 + 8 = 21
