Determine the number of possible triangles, ABC, that can be formed given A = 150°, a = 7, and b = 4.

1 answer:

8 0

1.

When you have the length of two sides and the angle between them, the triangle is totally determined. This is, there is only one segment that can complete the triangle: its length and position is totally fixed.

In a jar of marbles 9 out of 15 marbles are purple. Of there are 400 marbles in the jar, how many of th are not purple?

kramer

Answer:

C) 160

Step-by-step explanation:

Set up a proportion:

$\frac{9}{15}$ = $\frac{x}{400}$

Cross multiply and solve for x:

15x = 3600

x = 240

This means in 400 marbles, 240 are purple.

To find how many are not purple, subtract 240 from 400:

400 - 240

= 160 marbles

So, 160 marbles are not purple

I think 484 is the answer because, 0=t(-16t+176) x=0 and x=11.To get the add up the x intercepts and divide by 2 you should get that x=5.5.

The domain and range for function g are D(−infinity symbol, infinity symbol) and R(−infinity symbol, infinity symbol). Describe

Finger [1]

The answer is d: As x gets closer to 3, the value of g gets closer to 4.

The limit of a function h of x as x approaches the value a, written as $\lim_{x \to a} h(x) = L$ is the value the function h(x) approaches as x tends to the value "a", written as x → a. In this case, L.

Given the domain and range for function g are D(−∞, ∞) and R(−∞, ∞) and that the limit as x approaches 3 of the function g of x equals 4.

This implies that as x gets closer and closer to 3, the value of g gets closer and closer to 4.

Since the value g gets closer to is 3 as x gets closer to 4, we can write that the limit as x approaches 3 of the function g of x equals 4.

we can write this as

$\lim_{x \to 3} g(x) = 4$
