When it was 70 degrees outside, 50 members showed up at the beach club. for each degree temperature rose, another 10 members cam
stellarik [79]

Answer:

f(t)=50+10(t-70)

Step-by-step explanation:

Let the outside temperature be t degree.

So, when t=70 degree, number of members, f(t)=50

Now, for every degree rise in temperature, 10 members gets added.

So, when the temperature is t degrees, rise in temperature is (t-70) degrees.

Therefore,

For (t-70) degrees rise, number of members added = 10(t-70)

Hence, total number of members added as a function of temperature is given as the sum of members at t= 70 degrees and for (t-70) degrees rise. This gives,

f(t)=50+10(t-70)

Suppose a triangle has two sides of length 32 and 35, and that the angle between these two sides is 120°. What is the length of
dezoksy [38]

Answer:

A. 58.04°

Step-by-step explanation:

Let the sides of the triangle be A , B  and C.

A = 32

B = 35

C = what we don't know.

The opposite angle to C is 120° and its just denoted as ∡C

The formula to find C² = A² + B² - 2ABcos∡C

C² = 32² + 35² - 2(32)(35)cos120°

C² = 1024 + 1225 - 2240cos120°

C² = 3369

C = \sqrt{3369} ≅ 58.04°

Parallelogram ABCD has the coordinates shown. A(-3,2) B(0,4) C(3,4) Find the coordinates of point D. A) (0, 1) B) (1, 2) C) (2,
kupik [55]
In a parallelogram opposite sides are equal and parallel;
Therefore, in this case, AB is equal and parallel to CD, thus, the magnitude of AB is equal to the magnitude of CD
The line BC is equal to line AD and the two lines are parallel to y-axis; 
Since; AB = B - A = (0,4) - (-3,2)= (2,3)
 Assuming the coordinates of D is (x,y) DC= (4-y), (3-x) = (2,3)
Hence; y = 2 and x = 0
Thus; the coordinates of D are (0,2)
