Solve with the law of sine

Zinaida [17]

1) Triangle QRT, where q = 32.4 ft, r = 29.8 ft, t = 42.1 ft

No this cannot make a second triangle

2) Triangle ABC, where B = 62°, a = 11.52 m, c = 19.34 m

No this cannot make a second triangle

3) Both of the triangles cannot make a second triangle

The following is a detailed explanation of the sine law: In a triangle, side "a" divided by angle sine "a" equals side "b" divided by angle sine "b" equals side "c" divided by angle sine "c."

The formula for law of sine is written as

Sine A a = Sine B/ b = Sine C / c

These law helps in determining the given angles and sides

For the situation given; both cannot be used to make a second triangle

Find the value of w-9 given that –3w+5 = 2

melamori03 [73]

Answer:

$-8$

Step-by-step explanation:

Solving for $w$ given the equation, $-3w +5 = 2$ :

$-3w +5 = 2 \\ -3w +5 -5 = 2 -5 \\ -3w = -3 \\ \frac{-3w}{-3} = \frac{-3}{-3} \\ w = 1$

Solving for $w -9$ when $w = 1$

$1 -9 \\ -8$

Select the true statement plzzzz need help ASAPPPPP

xxMikexx [17]

Answer:

Correct choice is B

Step-by-step explanation:

All three functions are increasing when x is increasing. You can find values of each function when x is "enough large". For example, at x=100,

1. linear function: $y=10\cdot 100=1,000.$

2. exponential function: $y=5^{100}\approx 0.8\cdot 10^{70}.$

3. quadratic function: $y=4\cdot 100^2+5\cdot 100=40,500.$

As you can see, when x approaches positive infinity, the exponential function will exceed both the linear and the quadratic functions.

Also you can use graphical method to get from the attached diagrams result. When x approaches positive infinity, the exponential function will exceed both the linear and the quadratic functions.

Correct choice is B.
