What is the equation of the function that is graphed as line a?

Mathematics
1 answer:
Andrei [34K]3 years ago

Answer:

B

Step-by-step explanation:

We see that the line intersects the y-axis at -1.  As a result, we need to choose an equation with -1, either B or C.  We see that the different is the slope.  For choice B, the slope is \frac{1}{3}, meaning that every unit up equates to 3 blocks to the right.  Counting along the line, we see that this is correct.

What is the measure of angle J in the triangle below? <br> A. 99<br> B. 42 <br> C. 9<br> D. 48
Leya [2.2K]
For this use the law of sines:
\sin( \alpha ) \div a = \sin( \beta ) \div b \\ \sin( \alpha ) \div 11 = \sin(103) \div 16
\frac{ \sin( \alpha ) }{11} = \frac{0.97}{16}
cross-multiply:
16×sin (J) = 11×0.97
sin(J) = 10.72/16
sin(J) = 0.67
hit the "arcsin" button on your calculator:
{ \sin}^{ - 1} (0.67) = 42.06 = 42.1 \: deg
therefore answer B. 42 is the correct answer!!

How do I solve this problem. I have to find the missing side lengths and lease my sender as radicals in simplest form
nlexa [21]

Answer:

x = y = 2√2

Step-by-step explanation:

Find the diagram attached

To get the unknown side x and y, we need to use the SOH CAH TOA identity

Opposite side = x

Adjacent = y

Hypotenuse = 4

Sin theta = opposite/hypotenuse

sin 45 = x/4

x = 4 sin 45

x = 4 * 1/√2

x = 4 * 1/√2 * √2/√2

x = 4 * √2/√4

x = 4 * √2/2

x = 2√2

Similarly;

cos theta = adjacent/hypotenuse

cos 45 = y/4

y = 4cos45

y = 4 * 1/√2

y = 4 * 1/√2 * √2/√2

y = 4 * √2/√4

y = 4 * √2/2

y = 2√2
