What restrictions are there on the range of the function H(w) below?
H(w)
(5.0,20.00)
A. H(w) s 1
B. H(w) > 0
C. H(w) < 0
D. There are no restrictions on the range of H(w).

Answers

Answer:

There are no restrictions on the range of H(w).

The restrictions that are there on the range of the function H(w) is:

Option B: H(w) > 0

How to Identify the Function restrictions?

The function, named H(w) is defined by a graph that is a descendant line, that belongs only to the first quadrant.

As w approaches to 0 by the right, the function approaches to + infinity. It never touches the vetical axis, decreases and approaches to 0 when w approaches to infinity. The graph never touches the horizontal - axis.

Then, the function is defined only for positive values of w and H(w) is always positive.

Then, the answer is H(w) > 0, this is the option B

The actual cut should be 16 inches

Question: pentagon STUVW is similar to S' T' U' V' W'. angle U=56 degrees, angle U' = 3x-16, and Angle T'=x+46. ST=57, UV=63, S' T'=19 and U' V' =y+4
a. Find x
b. find angle T'
c. Find y
you have to do, a, b, and c

Answers

Answer:

Similarity doesn't changes angle measures

∠U = 56°, ∠U' = 3x - 16∠U = ∠U'

a) 3x - 16 = 56 ⇒ 3x = 72 ⇒ x = 24°

b) ∠T = x + 46 = 24 + 46 = 70°

c) Scale factor:

k = S'T'/ST = 19/57 = 1/3

Find y using known sides and scale factor:

U'V'/UV = 1/3(y + 4)/63 = 1/3y + 4 = 21y = 21 - 4y = 17

Elena bowls two games on Saturday. Her score in the second game is 30 more than ¾ of her score the first game. Elena's total score for the two games is 478. Write and solve an equation to demonstrate the points scored in her second game.

Answers

Answer:

222 = score in 2nd game

Step-by-step explanation:

Let x = score in 1st game

3/4(x) + 30 = score in 2nd game

x + 3/4(x) + 30 = 478         Multiply thru by 4 to eliminate the fraction

4x + 3x + 120 = 1912

7x + 120 = 1912

7x = 1792

x = 256

3/4(x) + 30 = 3/4(256) + 30

= 192 + 30

222 = score in 2nd game

Check:  222 + 256 = 478

The radius of a quarter circle is 3 millimeters. What is the quarter circle's area?
r=3 mm

Answers

Answer:

28.3mm

Step-by-step explanation:

3(3)=9(pi)= 28.274...

Answer: 9[tex]\pi[/tex], or more specifically, 28.26, or even more specifically, 28.2643.

Explanation:

To find the area of a circle, you need to do r squared x pi. Since pi repeats randomly infinitely, we are going to simplify it to 3.14. 3 squared or 3 x 3 equals 9. 9 x 3.14 = 28.26. Therefore, the area of the quarter is 28.26. If you want to find the answer without simplifying pi, it is approximately 28.2643. You can also write it as 9[tex]\pi[/tex].
