Answer:

n =

Step-by-step explanation:

Although the image is not shown, I imagine that what they are asking (n) is the length of the segment that joins both points. If that is the case, we first proceed to identify each of the given points with the general form of coordinate pairs on the plane. For example, we identify:

(-3,-2) = (x_1,y_1)\\(2,4)=(x_2,y_2)\\

Now we use the distance formula replacing the general coordinates by the given values as follows:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\d=\sqrt{(2-(-3))^2+(4-(-2))^2}\\d=\sqrt{5^2+6^2} \\d=\sqrt{25+36} \\d=\sqrt{61}

Answer:

A - The sum of a unknown value times 3 and 5. B - The sum of a unknown number subtracted by 2 being multiplied by 4.

Step-by-step explanation:

A - The sum of a unknown value times 3 and 5. B - The unknown value subtracted by 2, then multiplied by 4.

Step-by-step explanation:

So, lets pick apart the expressions.

We know the variables will be unknown values:

3unknown value + 5

We know that a number in front of a variable is multipication, so:

3 times unknown value + 5

We know there is a addition symbol, which means a sum of two numbers.  

So:

3 times a unknown value and the sum of 5

5 is just 5, so we can write it as it is.

This might be read as 3 times both the 5 and unknown value, so we want to make sure they are seperate:

3 times a unknown value plus by 5

So basically, instead of talking about the sum of the two numbers, I used plus so that the numbers are seperate. THis way there is no confusion in the answer.  

Next we have 4(x-2)

So first off, x is our unknown value:

4(unknown value-2)

- is subtraction, so:

4(unknown value subtracted by 2)

2 remains as 2.

4 is multiplying the parenthese, so basically, the x-2 is done first. THen it is multiplied by 4. This means the multiplied by 4 should come after the unknown value si subtracted by 2:

The unknown value subtracted by 2, then multiplied by 4.

I used a then to seperate the unkownv alue subtracted by 2 and the multiplied by 4.

A 36 year old male will pay $4.55 per $1,000 for a 10 year policy,

He bought a $150,000 policy:

150,000 / 1000 = 150

Multiply the rate per 1000 by 150:

4.55 x 150 = 682.50

His annual premium is $682.50

Does anyone know how to solve this?
Charra [1.4K]

Answer:

\frac{\sqrt{2}}{2}

Step-by-step explanation:

This almost looks like the left hand side of the following identity:

\sin(A)\cos(B)-\sin(B)\cos(A)=\sin(A-B) .

Here are similar identities in the same category as the above:

\sin(A)\cos(B)+\sin(B)\cos(A)=\sin(A+B)

\cos(A)\cos(B)-\sin(A)\sin(B)=\cos(A+B)

\cos(A)\cos(B)+\sin(A)\sin(B)=\cos(A-B)

Things to notice: 90-76=14. and 90-59=31.

This means we will possibly want to use the following co-function identities:

\cos(90-A)=\sin(A)

\sin(90-A)=\cos(A)

So let's begin:

\sin(76)\cos(31)-\sin(14)\cos(59)

Applying the co-function identities:

\cos(14)\cos(31)-\sin(14)\sin(31)

Applying one of the difference identities above with cosine:

\cos(31+14)

\cos(45)

45 is a special angle so \cos(45) is something you find off most unit circles in any trigonometry class.

\cos(45)=\frac{\sqrt{2}}{2}
