Answer:

1. CE = 63
2. x = 16

Step-by-step explanation:

Use proportions to solve.

Corresponding sides have same ratio.

<u>Question 1</u>

DE/EG = CE/EF

(6x + 3)/17 = (8x - 1)/21
21(6x + 3) = 17(8x - 1)
126x + 63 = 136x - 17
10x = 80
x = 8

CE = 8*8 - 1
CE = 63

<u>Question 2</u>

KM/MD = KZ/ZH

(x + 8)/21 = 32/28
x + 8 = 21*8/7
x + 8 = 24
x = 24 - 8
x = 16

Find Domain of function using Interval Notation

tensa zangetsu [6.8K]

[ - 4 , 4 ) ∪ ( 4 , ∞ )

The denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the value that x cannot be.

solve x - 4 = 0 ⇒ x = 4 ( is a vertical asymptote )

There is a zero when the numerator equals zero.

x + 4 = 0 ⇒ x = - 4 ( is a zero )

domain is [-4 , 4 ) ∪ ( 4 , ∞ )

Need help with this. Hope someone can help

To solve this problem, we must remember that the formula for volume is V = lwh, where l represents length, w represents width, and h represents height. Since we know the respective values for length, height, and volume, we can substitute those into the formula and then solve for the width, as modeled below:

30,000 cm³ = 30 cm * w * 500 mm

We must recognize first, though, that one of the values is given in millimeters, not centimeters. To continue solving this problem, we must convert this value to centimeters, using our knowledge that 1 cm = 10mm. This means that 500 mm = 50 cm, so we can substitute this into our equation below:

30,000 cm³ = 30 cm * w * 50 cm

To begin to solve this equation, we should first multiply all of the factors together on the right side of the equation, which gives us:

30,000 cm³ = 1,500w cm²

Next, we must divide both sides of the equation by 1,500 in order to get the variable w alone on the right side of the equation.

20 cm = w

Therefore, the width of the figure shown above is 20 cm.

Hope this helps!

What is the period of the function y = 2sin x?. A. 2Pi. B. Pi. C. [-2,2]. D. All Real Numbers

Morgarella [4.7K]

Answer:

Step-by-step explanation:

The given function is

$y=2sin(x)$

Notice that the indepedent variable doesn't have any transformation, that means the period doesn't change. In other words, this function has the same period than its parent function which is $2\pi$ .

Therefore, the answer is A.

The image attached shows the graph of this function, there you can observe the period of the function.

Also, notice that this function is verticall stretched by a scale of 2, which doesn't change its original period.
