I need help finding if it’s either SOH, CAH or TOA and the indicated side of the triangle, thank you!

Brilliant_brown [7]

Answer:

$\huge\boxed{IJ \approx 2.01}$

Step-by-step explanation:

In order to find the side mentioned (IJ), we need to use SOH CAH TOA.

SOH CAH TOA is an acronym to help us remember what sin, cos, and tan mean. It stands for:

Sin = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tan = Opposite / Adjacent

Since we know the measure of angle K (42) and we know one of the sides, we can use this to find the missing length.

Since the side given to us is the hypotenuse, and we're looking for the side opposite of the angle (IJ), the only possible one to use would be SIN as it includes Opposite and Hypotenuse.

Our equation is now this: $\text{sin(42)} = \frac{x}{3}$

Let's now solve for x.

$\text{sin(42)} = \frac{x}{3}$
$3 \cdot \text{sin(42)} = x$
$\text{sin(42)} \approx 0.67$
$3 \cdot 0.67 \approx 2.01$

Therefore, the length of IJ will be around 2.01.

Hope this helped!

Help! I have looked at so many lessons on writing exponential functions from a graph and nothing has helped.

Over [174]

Answer:

y = $8(-\frac{1}{2})^x$

Step-by-step explanation:

Let the equation of the exponential function is,

y = a(b)ˣ

Since the graph of this function passes through two points $(4, \frac{1}{2})$ and (3, -1)

For the point $(4, \frac{1}{2})$ ,

$\frac{1}{2}=a(b)^4$ ---------(1)

For second point (3, -1),

-1 = a(b)³ ---------(2)

Divide equation (2) by equation (1),

$\frac{\frac{1}{2}}{-1}$ = $\frac{a(b)^4}{a(b)^3}$

$-\frac{1}{2}=b^{(4-3)}$

$-\frac{1}{2}=b$

From equation (2)

-1 = $a(-\frac{1}{2})^3$

-1 = $-\frac{1}{8}a$

a = 8

Therefore, equation of the exponential function will be,

y = $8(-\frac{1}{2})^x$

NEED AS SOON AS POSSIBLE!!!

kati45 [8]

Answer:

Step-by-step explanation:

Let Kaylee used the amount of green paint in the mixture = x ounces

and the amount of white paint = y ounces

Total amount of mixture = 50 ounces

Equation will be x + y = 50 ------(1)

Ratio of green paint to the white paint in the mixture = 5 : 3

⇒ x : y = 5 : 3

⇒ $\frac{x}{y}=\frac{5}{3}$

⇒ x = $\frac{5}{3}y$ ---------(2)

Therefore, By solving these two equations by substitution method we can get the amount of green and white paint used in the mixture.

4 glue sticks cost $7.76<br><br> Which equation would help determine the cost of 13 glue sticks?

Elza [17]

Answer:

$y=1.94x$

13 glue sticks cost $25.22.

Step-by-step explanation:

4 blue sticks cost $7.76, this means that one glue stick costs

$7.76/4 = $1.94.

Let $y$ be the cost of the glue sticks, and $x$ be the number of glue sticks; then

$\boxed{y=1.94x}$

We can use this equation to find the cost of 13 glue sticks; we just put $x=13\$ into our equation and it gives:

$y=1.94(13)=25.22$

So 13 glue sticks cost $25.22.
