The length of side q to the nearest 10th of an inch is 4.1 inches.

The sine rule for a triangle ABC is a/sinA = b/sinB = c/sinC.

Given, In ΔPQR, p = 4.7 inches, ∠P=76°, and ∠Q=57°.

∴  the length of q can be obtained by,

p/sinP = 1/sinQ.

4.7/sin76° = q/sin57°.

4.7/0.97 = q/0.84.

q = (4.7×0.84)/0.97.

q = 4.1 inch.

The vertices after reflection will be (-6, 1), (-3, 2), (-5, 7) and the vertices after rotation of 180° will be (6, 1), (3, 2), (5, 7).  

A form of Euclidean space isometry in geometry is called a point reflection, also known as a point inversion, center inversion, or asymmetry through a point.

An object is said to have point symmetry if it is unchanged under a point reflection, and central symmetry or being centrally symmetric if it is invariant below a point reflective thinking through its center.

As per the given information in the question,

The given vertices of the triangle are:

D(-6, -1), E(-3, -2), F(-5, -7).

a.

The equation towards reflection in the x-axis: (x, -y)

D = (-6, -1)

Reflected vertex = (-6, 1)

E = (-3, -2)

Reflected vertex = (-3, 2)

F = (-5, -7)

Reflected vertex = (-5, 7)

b.

Now let's find out the rotation of 180° of the given points,

As we can see that the vertices are in the third quadrant because both the points of each vertex are negative, so after rotation of 180° it will move to the 1st quadrant where all the points are positive.  

So,

D = (-6, -1)

After rotation, D = (6, 1)

E = (-3, -2)

After rotation, E = (3, 2)

F = (-5, -7)

After rotation, F= (5, 7)

The fourth degree polynomial function with zeros 5, -5, 5i, and -5i. written  in factored form is

The zeros of a polynomial function is the the value of x when the function is equal to zero

The zero is also called the root of the polynomial

To find the polynomial we equate to the zeros

the first

x = 5

x - 5 = 0

the second

x = -5

x + 5 = 0

the third

x = 5i

x - 5i = 0

the fourth

x = -5i

x + 5i = 0

Bringing the terms together

(x - 5) (x + 5) (x - 5i) (x + 5i)

Therefore the polynomial of zeros 5, -5, 5i, and -5i is gotten in factored form in the form (x - 5) (x + 5) (x - 5i) (x + 5i)

The monomial that we need to add to have a square of a difference is:

-2bc

Remember that the square of a difference is written as:

(a - b)^2 = a^2 - 2ab + b^2

Here we have the two  terms:

0.01*b^2 + ... + 100c^2

We can rewrite the known terms as:

0.01*b^2 = (0.1*b)^2

100*c^2 = (10c)^2

Then our expression becomes:

The equation for the given linear function is y = 12m + 20.

A linear equation in two variable has the general form as y = ax + by + c, where a, b and c are integers and a, b ≠ 0.

It can be represented as a straight line on a graph.

The given points for the linear function are (2, 44) and (5, 80) respectively.

The slope can be obtained as,

m = (80 - 44)/(5 - 2)

   = 36/3

   = 12

Substitute the value of m in the general form y = mx + c to obtain,

y = 12x + c

Now, substitute x = 2 and y= 44 in the above expression as,

44 = 12 × 2 + c

=> c = 44 -24

=> c = 20

Thus the linear function can be written in the form of equation as,

y = 12m +  20

Hence, the equation of the function for the given case is y = 12m + 20.

The order pair will be greater than (-2,5) because when substituted the value (-2,5) will give 11 that will be false.

An ordered pair is made up of the ordinate and the abscissa of the x coordinate, with two values given in parenthesis in a certain sequence.

The correct answer is option B: "g(-4) = -11". This statement is consistent with the given information about the domain, range, and specific values of the function g. Since the domain of g is -20 ≤ x ≤ 5, the value x = -4 is within the domain of the function, and therefore we can evaluate g at this value. Similarly, since the range of g is -5 ≤ g(x) ≤ 45, the value g(-4) = -11 is within the range of the function. Furthermore, since g(0) = -2 and g(-9) = 6, we know that g takes on negative values, which is consistent with the fact that g(-4) = -11.

Option A, C, and D are all incorrect because they do not satisfy the conditions of the domain and range of the function g. For example, option A states that g(-13) = 20, but since the domain of g is -20 ≤ x ≤ 5, the value x = -13 is not within the domain of the function, and therefore it is not possible to evaluate g at this value. Similarly, option C states that g(7) = -1, but since the range of g is -5 ≤ g(x) ≤ 45, the value g(7) = -1 is not within the range of the function, and therefore this statement cannot be true for g. Option D states that g(0) = 2, but since we are given that g(0) = -2, this statement is not consistent with the given information about the function g.

Part A)

The given expression is in the form y = -16t^2 + 441, which is a quadratic equation. A quadratic equation can be factored into the form (ax + b)(cx + d) = 0, where a, b, c, and d are constants.

To factor in the given expression, we can start by completing the square. To complete the square, we need to add and subtract the square of half of the coefficient of the x^2 term, which is (1/2)(-16) = -8. This gives us:

y = -16t^2 + 441 = (-16t^2 - 8t^2) + 441 = -24t^2 + 441

Now, we can rewrite the expression as follows:

y = -24t^2 + 441 = (-8t^2) + 441

To complete the square, we need to add and subtract (1/2)^2(-8)^2 = 16:

y = (-8t^2 + 16) + 425

This expression can be rewritten as:

y = (-8t^2 + 16) + (20t)^2

So the expression can be factored as:

y = (-8t + 4)(2t - 5) (this is the answer)

Part B)

To find the time it takes the object to fall to a height of 377 feet, we can set y equal to 377 and solve for t. Substituting the factored form of the expression into the equation and solving for t gives us:

377 = (-8t + 4)(2t - 5)

We can then solve this equation by setting each factor equal to 0 and solving for t. This gives us:

-8t + 4 = 0

2t - 5 = 0

Solving these equations separately gives us:

t = 1/2

t = 5/2

The time it takes the object to fall to a height of 377 feet is t = 1/2 seconds. (or 0.5 in decimal form)

Option B is correct, Vincent will be able to buy the sneakers, while David will not be able to.

Because the shoe cost after including sales tax is

David only has 90$ so he can't afford the sneakers. They are 1.16$ over his budget.

While for Vincent,

9% of 86$ is 7.74$

so, 86 + sales tax (which in this case is 7.74) = 93.74

A sales tax is a tax paid to a governing body for the income of certain items and services. Typically, legal guidelines permit the seller to gather funds for the tax from the customer at the factor of purchase. While a tax on goods or services is paid to a governing body immediately by means of a patron, it also includes called a use tax. frequently legal guidelines offer for the exemption of positive goods or services from income and use tax, which includes food, schooling, and medicines. A fee-introduced tax (VAT) collected on goods and services is associated with a sales tax. See the contrast with income tax for key variations.

Traditional or retail income tax is levied at the sale of an amazing to its very last quit person and is charged whenever that item is sold retail. sales to corporations that later resell the products aren't charged the tax. A patron who isn't always an end-user is generally issued a "resale certificate" by way of the taxing authority and required to provide the certificate (or its identification variety) to a seller on the point of buy, at the side of an assertion that the object is for resale. The tax is otherwise charged on each item sold to clients without any such certificate and who are underneath the jurisdiction of the taxing authority.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is given as

f ( x ) = 2x + 5

Now , the values of the function f ( x ) can be determined when we substitute for the values for x in the equation

So , in order to find f ( 0 ) , substituting the value for x as x = 0, we will get the value for the function

a)

when x = 0

The equation is f ( x ) = 2x + 5

f ( 0 ) = 2 x 0 + 5

f ( 0 ) = 5

So , the value of f ( 0 ) = 5

b)

when x = 1

The equation is f ( x ) = 2x + 5

f ( 0 ) = 2 x 1 + 5

f ( 0 ) = 7

So , the value of f ( 0 ) = 7

c)

when x = 5

The equation is f ( x ) = 2x + 5

f ( 0 ) = 2 x 5 + 5

f ( 0 ) = 15

So , the value of f ( 0 ) = 15
