Answer:

B (or top right)

Step-by-step explanation:

The equation is written using the y = mx + b format.

m = slope

b = y-intercept

Top right because 3 is the y intercept and it goes down by 2 for every 1 x

Answer: HOPE THIS HELPED! ;D :P

2.075 white paint

Step-by-step explanation:

8.3 x 3/4 = 6.225 blue paint

8.3 - 6.225 = 2.075 white paint

Which choice answer is it?

nekit [7.7K]

Answer:

2. a1 = 10 and an = a(n-1) + 2

Step-by-step explanation:

10 is our first term so it would be a of 1.

Then, in this arithmetic sequence, it is increasing by 2.

So, therefore our recursive formula for this arithmetic sequence would be:

a(n) = a(n-1) + 2

Use the Law of Sines to solve for all possible triangles that satisfy the given conditions. (If an answer does not exist, enter

tresset_1 [31]

Answer:

For a triangle with a = 33, c = 48 and the angle $\alpha=33^o$ , the missing side is b = 60.4, and the missing angles are $\beta=94.6^o$ and $\gamma = 52.4^o$ .

Step-by-step explanation:

The Law of Sines says that in any given triangle, the ratio of any side length to the sine of its opposite angle is the same for all three sides of the triangle. This is true for any triangle, not just right triangles.

$\frac{\sin\alpha}{a} = \frac{\cos\beta}{b} = \frac{cos\gamma}{c}$

We know two sides a = 33, c = 48 and the angle $\alpha=33^o$ , so we use the law of sines to find the angle $\gamma$ as follows:

$\frac{ 33 }{ \sin(33^o) } =\frac{ 48 }{ \sin(\gamma) }\\\\\sin(\gamma) \cdot 33 = 48 \cdot \sin(33^o)\\\sin(\gamma) \cdot 33 = 48 \cdot 0.5446\\\sin(\gamma) \cdot 33 = 26.1427\\\sin( \gamma ) = 0.7922\\\gamma = 52.4^o$

One of the basic properties of triangles is that the sum of the measure of angles, in every triangle, is 180°.

So,

$180=\alpha+\beta+\gamma\\180=33+\beta+52.4\\\beta+85.4=180\\\beta=94.6^o$

To find the side b we use the law of sines:

$\frac{ 33 }{ \sin(33^o) } =\frac{ b }{ \sin(94.6^o) }\\\\b=\frac{33\sin \left(94.6^{\circ \:}\right)}{\sin \left(33^{\circ \:}\right)}\\\\b=60.4$
