Which statements are true about polygons? Select three options. All sides and all angles in a polygon are congruent. The sides of a polygon are segments that intersect exactly two other segments, one at each endpoint. In a polygon, all segments with a common endpoint are collinear. If all of the sides of a convex polygon are extended, none of them will contain any points that are inside the polygon. The extension of at least one side or diagonal in a concave polygon will contain a point that is inside the polygon.

Step-by-step explanation:

If the function is translated 2 units down and 1 unit to the left. Then the function will be f(x) = |x + 1| - 2

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

The function is f(x) = |x|.

If the function is translated 2 units down and 1 unit to the left. Then the function will be

f(x) = |x + 1| - 2

Answer:   y= 64  

Step-by-step explanation:

If y is 16 when  x is 2  This means if  x is 8 y will be 64.

Set up the proportional equation

[tex]\frac{2}{16} = \frac{8}{y}[/tex]     Cross multiply  

2y = 128

y= 64

The value of y when x=8 is 256.

It is given that

y ∝ x²

So, y = kx²....(1)

where k = constant of proportionality

It relates two parameters that are mutually dependent.

It is given that

When, x=2, y=16

This means, (1) becomes, 16=k.2² ⇒k =4

So, (1) becomes, y =4x²

So, when x= 8, y= 4*8²

So, y =256 when x=8

Therefore, The value of y when x=8 is 256.

Step-by-step explanation:

189 divided by 21 is 9 (:

Answer:

9m

Step-by-step explanation:

To find the width of a rectangle given area and length all you need to do is take your area (189 in this case) and divide it by your length. (In this case 21.)

Here's our equation:

189 ÷ 21 = 9

(remember the meters squared is important if you're finding area. This doesn't apply in our case as we're only finding the width. To be more clear the "m² and/or m^2")

9m is your answer.

 — • ——

 4   7

Step-by-step explanation:

The width of each interval is Δx = (4−1)/6 = 1/2.

a) Evaluate the function at the beginning and end of each interval.

f(x) = 7√(ln x)

f(1) = 7√(ln 1) = 0

f(1.5) = 7√(ln 1.5) ≈ 4.4573300

f(2) = 7√(ln 2) ≈ 5.8278823

f(2.5) = 7√(ln 2.5) ≈ 6.7006153

f(3) = 7√(ln 3) ≈ 7.3370295

f(3.5) = 7√(ln 3.5) ≈ 7.8348826

f(4) = 7√(ln 4) ≈ 8.2418702

Calculate the area of each trapezoid.

T₁ = ½ (0 + 4.4573300) (1/2) = 1.1143325

T₂ = ½ (4.4573300 + 5.8278823) (1/2) = 2.5713031

T₃ = ½ (5.8278823 + 6.7006153) (1/2) = 3.1321244

T₄ = ½ (6.7006153 + 7.3370295) (1/2) = 3.5094112

T₅ = ½ (7.3370295 + 7.8348826) (1/2) = 3.7929780

T₆ = ½ (7.8348826 + 8.2418702) (1/2) = 4.0191882

The total area is therefore:

T = 1.1143325 + 2.5713031 + 3.1321244 + 3.5094112 + 3.7929780 + 4.0191882

T = 18.139337

b) Evaluate the function at the midpoint of each interval.

f(1.25) = 7√(ln 1.25) ≈ 3.3066651

f(1.75) = 7√(ln 1.75) ≈ 5.2365230

f(2.25) = 7√(ln 2.25) ≈ 6.3036165

f(2.75) = 7√(ln 2.75) ≈ 7.0404861

f(3.25) = 7√(ln 3.25) ≈ 7.5996115

f(3.75) = 7√(ln 3.75) ≈ 8.0477348

Calculate the area of each rectangle.

M₁ = (3.3066651) (1/2) = 1.6533325

M₂ = (5.2365230) (1/2) = 2.6182615

M₃ = (6.3036165) (1/2) = 3.1518082

M₄ = (7.0404861) (1/2) = 3.5202431

M₅ = (7.5996115) (1/2) = 3.7998057

M₆ = (8.0477348) (1/2) = 4.0238674

The total area is therefore:

M = 1.6533325 + 2.6182615 + 3.1518082 + 3.5202431 + 3.7998057 + 4.0238674

M = 18.767318

c) Simpson's rule can be calculated as:

S₆ = Δx/3 [f(x₀) + 4f(x₁) + 2f(x₂) + 4f(x₃) + 2f(x₄) + 4f(x₅) + f(x₆)]

S₆ = (1/2)/3 [0 + 4(4.4573300) + 2(5.8278823) + 4(6.7006153) + 2(7.3370295) + 4(7.8348826) + 8.2418702]

S₆ = 18.423834

Answer:

10/3

Step-by-step explanation:

Answer: The musical group sold  60%of the white hats and  70%of the black hats.

A greater percentage of  black hats were sold.

Step-by-step explanation: to answer this question we have to divide the number of hats sold by the number of total hats for each case.

Then, we have to multiply that result by 100, to obtain the result in percentage form.

White Hats: (120/200) x 100 =60%

Black hats: (210/300) x 100= 70%

The musical group sold 60%of the white hats and 70%of the black hats.  

A greater percentage of black hats were sold. (Since 70 > 60 )

Answer: B. (0,-10)

(I got it right in the exam review.)

Answer:

The answer is B.

Step-by-step explanation:

Steps to solve:

(12x + 4) - 8 = 12

~Combine like terms

12x - 4 = 12

~Add 4 to both sides

12x = 16

~Divide 12 to both sides

x = 16/12 or x = 4/3

Answer: 315 miles

Step-by-step explanation:

let onward speed = x mph, then distance = 7x

return speed = (x+18) mph, (same) distance = 5(x+18)

equating the two,

7x = 5(x+18)

2x = 90 ==> x = 45 mph

so distance = 7*45 = 315 miles
