Hiw do u get the third angle of a triangle? I was given 65 and 65?

2 answers:

The sum of the interior angles of a triangle are equal to 180o. To find the third angle of a triangle when the other two angles are known subtract the number of degrees in the other two angles from 180o

Add them both and then subtract the sum from 180
This is because every triangles total is 180

Two lines are parallel if and only if their slopes are equal. Write two if-then statement that are implied by this thesis statem

Veronika [31]

If and only if (iff) statements are true if only both statements are true of both are false, its double implied.
Here are the implications:
If two lines are parallel then their slopes are equal.
If the slopes of two lines are equal then they are parallel.

The table below represents the displacement of a horse from its barn as a function of time:

taurus [48]

"Part A: What is the y-intercept of the function, and what does this tell you about the horse? (4 points)" The y-intercept is (0,8), which tells us that at the beginning the horse is 8 miles from the barn.

"Part B: Calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points)" The value of the function at x=1 is 58 and that at x=3 is 158. Thus, the change in the horse's distance from the barn is 158-58, or 100 feet. The time period involved here is 2 sec. Thus, the average rate of change of the horse's position with respect to time is

100 feet

average rate of change = ---------------- = 50 ft/sec

2 sec

If the horse were to move steadily at a fixed rate from 58 feet to 158 feet from the barn, its average rate would be 50 ft/sec.

"Part C: What would be the domain of the function if the horse continued to walk at this rate until it traveled 508 feet from the barn? (2 points)"

Here time begins at x=0 and ends at x=4 sec. Thus, the appropriate domain here is [0,4] sec.

A survey of 1,390 parents of 13- to 17- year-olds found that 653 of 1,390 parents have checked their teen's social media profile

atroni [7]

Answer:

Total number of population = 2043

Step-by-step explanation:

According to the question

Total number of parents = 1390

number of parents checked their teens social media = 653

⇒ Total number of population = 653 +1390

Total number of population = 2043

What is the smallest positive integer for x so that f(x)=200(2)* is greater than the value of g(x)=500x+400?

Goshia [24]

We have to functions, namely:

$f(x)=200(2)^{x} \ and \ g(x)=500x+400$

So the problem is asking for the smallest positive integer for $x$ so that $f(x)$ is greater than the value of $g(x)$ , that is:

$f(x)\ \textgreater \ g(x) \\ \therefore 200(2)^{x}\ \textgreater \ 500x+400$

Let's solve this problem by using the trial and error method:

$for \ x=1 \\f(1)=400 \\ g(1)=900 \\ Then \ f(1) \ \textless \ g(1) \\ \\ \\ for \ x=2 \\f(2)=800 \\ g(2)=1400\\ Then \ f(2)\ \textless \ g(2) \\ \\ \\ for \ x=3 \\f(3)=1600 \\ g(3)=1900 \\ Then \ f(3)\ \textless \ g(3) \\ \\ \\ for \ x=4 \\f(4)=3200 \\ g(4)=2400 \\ \boxed{Then \ f(4)\ \textgreater \ g(4)}$

So starting $x$ from 1 and increasing it in steps of one we find that:

$f(x)>g(x)$

when $x=4$

That is, the smallest positive integer for $x$ so that the function $f(x)$ is greater than $g(x)$ is 4.
