What is the domain of the following points? Group of answer choices {-4, 1, 4} {-4, -1, 1, 4} {-1, 4, 1} {1, 4}

The altitude of the trapezoid, based on the given parameters is 5 units

From the question, we have the following parameters about the trapezoid

Base length 1 of the trapezoid = 6

Base length 2 of the trapezoid = 10

Area of the trapezoid = 40

Altitude of the trapezoid = h

The area of the trapezoid is calculated using

Area = 0.5 * (Sum of the two base lengths) * Altitude of the trapezoid

Substitute the given parameters in the above formula

40 = 0.5 * (6 + 10) * h

Evaluate the sum of 6 ad 10 (do not approximate)

40 = 0.5 * (16) * h

Evaluate the product of 0.5 and 16 (do not approximate)

40 = 8 * h

Divide both sides by 8 (do not approximate)

h = 5

Hence, the altitude of the trapezoid, based on the given parameters is 5 units

Answer:

1413.86 ft^2.

Step-by-step explanation:

The diameter of the circle = 50 - 2(18)

= 50-36

=  14 ft.

So its radius is 7 ft.

The total area of the blue shape

= 2(35 * 18) + 3.14*7^2

= 1413.86 ft^2.

Answer:

Yes

Step-by-step explanation:

First we need to determine how much money Allen has

2 dollars = 2.00

5 quarters = 5 * .25 = 1.25

2 dimes = 2 * .10 = .20

7 pennies = 7 * .01 = .07

Add this together

2.00 + 1.25+.20+.07 =3.52

3.52 > 3.50

This is more than 3.50 so he has enough money to buy the pencils

Answer:

b/a

Step-by-step explanation:

Perpendicular lines have slopes that are opposite sign and reciprocals (flipped over).

In the equation

ax + by = c,

the slope of the line is

-a/b

If you haven't memorized this pattern yet, you can calculate it by solving ax+by=c for y.

by = -ax +c

y = -a/b x + c/b

The slope is -a/b

So a perpendicular line would be opposite sign and flipped, b/a

The domain of f(x) is all set of real values while, the domain of g(x) is x ≤ -1 or x ≥ 2 and both functions have the same range

The functions are given as:

f(x) = x^4 - 2x^3 - 3x^2 + 4x + 4

g(x) = √(x^2 - x - 2)

Domain

The polynomial function f(x) has no restriction on its input.

So, the domain of f(x) is all set of real values

Set the radical of g(x) = √(x^2 - x - 2) greater than 0

x^2 - x - 2 ≥ 0

Factorize

(x + 1)(x - 2) ≥ 0

Solve for x

x ≥ -1 and x ≥ 2

Combine both inequalities

x ≤ -1 and x ≥ 2

So, the domain of g(x) is x ≤ -1 or x ≥ 2

Range

Using a graphical calculator, we have:

Hence, both functions have the same range

We have:

h(x) = (-x^2 + x)/(x^2 - x - 2)

Set the denominator to 0

x^2 - x - 2 = 0

The above represents the radical of the function f(x)

This means that the breaks in the domain of h(x) and the zeros of f(x) are the same

Answer:

20 cm

Step-by-step explanation:

When two triangles are similar, they're just dilated by a certain scale factor. In other words, each side is multiplied by the same value to create the similar triangle.

So to find this scale factor, we can use the two sides: 6 and 12, since we're going from the triangle with a 6 cm side to a 12 cm side, we divide 12 cm, by 6 cm to get a scale factor of 2

This means that the bottom side in the top triangle, which is 10 cm, is multiplied by a scale factor of 2, to get the new bottom side of x. So to find x, we simply multiply 10 cm by 2 to get 20 cm

Considering the relationship between velocity, distance and time, it is found that the total distance traveled was of 380 miles.

Velocity is distance divided by time, that is:

v = d/t.

For the first day, we have that:

v = 40, t = t + 2, d = d + 20, hence:

40 = (d + 20)/(t + 2)

For the second day, we have that:

v = 60

60 = d/t

d = 60t

Then, replacing in the first equation:

40 = (60t + 20)(t + 2)

60t + 20 = 40t + 80

20t = 60

t = 3.

By applying the theorem of intersecting secants, the measure of angle XYZ is equal to: A. 35°.

By critically observing the geometric shapes shown in the image attached below, we can deduce that they obey the theorem of intersecting secants.

The theorem of intersecting secants states that when two (2) lines intersect outside a circle, the measure of the angle formed by these lines is equal to one-half (½) of the difference of the two (2) arcs it intercepts.

By applying the theorem of intersecting secants, angle XYZ will be given by this formula:

<XYZ = ½ × (m<WZ - m<XZ)

Substituting the given parameters into the formula, we have;

<XYZ = ½ × (175 - 105)

<XYZ = ½ × 70

<XYZ = 35°.

By applying the theorem of intersecting secants, we can infer and logically deduce that the measure of angle XYZ is equal to 35°.

Total value of all coins together is $2.7

Linear equations are equations having variables with power 1. ax+b = 0 is an example with one variable where x is the variable, a and b are real numbers.

1 Nickel = $0.05 and 1 quarter = $0.25.

Let number of nickels and number of quarter be x.

According to the situation

x.(0.25) = $1.80 + x.($0.05)

x(0.25 - 0.05) = $1.80

x (0.2) = $1.80

x = $1.80/0.2

x = 9 coins

Therefore total value of the currency is 9(0.05 + $0.25) = 9 (0.3) = $2.7

Thus total value of all coins together is $2.7.

Using the algebraic equation, (2x + 6)/5 = 4x - 3, it has been proved that x = 7/6

Algebraic Proof for the Given Algebraic Equation

The given algebraic equation is,

(2x + 6)/5 = 4x - 3

2x + 6 = 5(4x - 3)

2x + 6 = 20x - 15

20x - 15 = 2x + 6

This algebraic equation can be written as,

20x - 2x - 15 = 6

18x = 15 + 6

18x = 21

x = 21/18

x = 7/6

The probability of selecting none of the correct six integers, when the order in which they are selected doesnot matter is 0.43.

According to thr question.

We have to find the probability of selecting none of the correct six integers from the positive integers not exceeding 48.  

Let E be the event of selecting 6 numbers from 40 and S be the sample space of all integers not exceeding 48.

Now,

The total number of ways of selecting 6 numbers from 48

[tex]= ^{48} C_{6}[/tex]

[tex]= \frac{48!}{6!\times 42!}[/tex]

[tex]= \frac{48\times 47\times46\times45\times44\times43\times42!}{6!\times\ 42!}[/tex]

= 8835488640/6!

And, the total number of ways of selecting 6 incorrect numbers from 42

= [tex]^{42} C_{6}[/tex]

[tex]= \frac{42\times41\times40\times39\times38\times37\times36!}{6!\times36!}[/tex]

Therefore, the probability of selecting none of the correct six integers, when the order in which they are selected does not matter is given by

[tex]= \frac{^{42C_{6} } }{^{48} C_{6} }[/tex]

[tex]= \frac{\frac{3776965920}{6!} }{\frac{8835488640}{6!} }[/tex]

The y-intercept of the equation  g(x) = 3^x - 5 is (0, -4) and the asymptote of the equation  g(x) = 3^x - 5 is y = -5

The equation of the function g(x) is given as:

g(x) = 3^x - 5

The y-intercept is a point on the graph where the value of x is 0

This is represented by x= 0 or (0, y)

This means that we substitute 0 for x in the above equation

So, we have:

g(0) = 3^0 - 5

Evaluate the exponent 3^0

g(0) = 1 - 5

Evaluate the difference of 1 and 5

g(0)  = -4

Rewrite this point as

(0, -4)

This means that the y-intercept of the equation  g(x) = 3^x - 5 is (0, -4)

The equation of the function g(x) is given as:

g(x) = 3^x - 5

The asymptote is a point on the graph where that is parallel to the graph
