Answer:

80

Step-by-step explanation:

So Nelly gets £8 an hour for the first 15 hours, so you have to find the product of 8 and 15 which is £120. Then she gets an extra £10 for every extra hour, so we have tl subtract 15 hours from how many total she worked. To do that, we first have to add all of the hours together which would be 22 hours. Then we have to subtract the 15 which is 7 hours. However, the 5 hours on Saturday are going to pay double so we will calculate that afterwards. so 7 minus 5 is 2. Nelly gets paid £8 pounds for every hour so she gets £16 for 2 hours. Now, since are doubling £8 we get £16. So Nelly gets paid £16 an hour for the hours she worked on Saturday. 5 times 16 is £80. Now we add it all together. £120 + £16 + £80 = £216

Hope this helps :)

Answer:

f(x)=a(x - h)2 + k

Much like a linear function, k works like b in the slope-intercept formula. Like where add or subtract b would determine where the line crosses, in the linear, k determines the vertex of the parabola. If you're going to go up 2, then you need to add 2.

The h determines the movement horizontally. what you put in h determines if it moves left or right. To adjust this, you need to find the number to make the parentheses equal 0 when x equals -2 (because moving the vertex point to the left means subtraction/negatives):

x - h = 0

-2 - h = 0

-h = 2

h = -2

So the function ends up looking like:

f(x)=a(x - (-2))2 + 2

Subtracting a negative cancels the signs out to make a positive:

f(x)=a(x + 2)2 + 2

Step-by-step explanation:

The translated value of the function is h ( x ) = ( x + 4 )² - 7

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units: y=f(x+c) (same output, but c units earlier)

Right shift by c units: y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k × f(x)

Horizontal stretch by a factor k: y = f(x/k)

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = x²

we can obtain the function h(x) by first translating it 4 units to the left, which gives us f(x + 4), and then translating it 7 units down, which gives us f(x + 4) - 7. Therefore, the function h(x) can be written as:

h(x) = f(x + 4) - 7

To write this in vertex form, we need to complete the square. First, we have:

h(x) = f(x + 4) - 7

h(x) = (x + 4)² - 7

This is the vertex form of the equation for h(x). The vertex of the parabola is at the point (-4, -7), which is obtained by setting x + 4 = 0 in the equation above.

The value of the vertex is -7, which is obtained by subtracting 7 from the squared term.

Therefore, the vertex form of the equation for h(x) is:

h ( x ) = ( x + 4 )² - 7

Hence , the transformed function is h ( x ) = ( x + 4 )² - 7

Answer:

Step-by-step explanation:

A polynomial is a finite sum of terms in which all variables have whole number exponents and no variable appears in a denominator.

box4aa

box1

rembox22

The leading term in a polynomial is the term of highest degree.

The constant term in a polynomial is the term without a variable.

Polynomials: YES or NO

3x½

NO - exponent is not a whole number

polyd

NO - the variable is in the denominator

-3x2

YES - satisfies the polynomial definition

polyd1

NO - the square root of x can be written with a fractional exponent of x.

2x-3

NO - exponent is not a whole number.

Negative exponent places x3 in denominator.

polyrad3

YES - the exponent of x is 1 which is OK.

The coefficient being radical 3 is not a problem.

Classification by Terms

monomial

one term: 12, 4x, x2, -5xy

binomial

two terms: 2x - 1, x2 - 4

trinomial

three terms: x2 + 2x + 1

polynomial - one or more terms: polynomial means "many", but it can also be one term.

The ending of these words "nomial"

is Greek for "part".

Classification by Degree

Linear - degree of 1 or 0:    3x + 1  or  12

Quadratic - degree of 2:   2x2 - x + 7

Cubic - degree of 3:   3x3 + 4x2 + 3x + 5

definition The degree of a term with whole number exponents is the sum of the exponents of the variables, if there are variables. Non-zero constants have degree 0, and the term zero has no degree.  Example: 6x2 has a degree of 2;   4x2y3 has a degree of 5 (the sum of 2 and 3).

definition

The degree of a polynomial is the highest degree of its terms.

Example: 3x2 + 4x + 1 has a degree of 2;  x3 - x2 + 5x - 2 has a degree of 3

The standard form of a polynomial is when all like terms are combined and the degrees are arranged in descending order.

Polynomial: 2x + 3x5 + 4x3 - 8

Standard form: 3x5 + 4x3 + 2x - 8

3x5 + 4x3 + 2x1 - 8x0

boxdegree1

Will we ever really use the degree?

Knowing the "degree" of a polynomial function will let you determine the most number of solutions the function may have, and the most number of times the function will cross the x-axis.

FYI: The standard form of a polynomial is formally written as anxn + an - 1xn - 1 + ... + a2x2 + a1x + a0, where n is a non-negative integer, and a0, a1, a2, ..., an are real number constant coefficients with an ≠ 0.

bullet Polynomials and Closure:

Polynomials form a system similar to the system of integers, in that polynomials are closed under the operations of addition, subtraction, and multiplication.

CLOSURE: Polynomials will be closed under an operation if the operation produces another polynomial.

• Closure under Addition: (2x2 + 3x + 4) + (x2 - 5x - 3) = 3x2 - 2x + 1

When adding polynomials, the variables and their exponents do not change. Only their coefficients will possibly change. This guarantees that the sum has variables and exponents which are already classified as belonging to polynomials. Polynomials are closed under addition.

• Closure under Subtraction: (2x2 + 3x + 4) - (x2 - 5x - 3) = x2 + 8x + 7

When subtracting polynomials, the variables and their exponents do not change. Only their coefficients will possibly change. This guarantees that the difference has variables and exponents which are already classified as belonging to polynomials. Polynomials are closed under subtraction.

• Closure under Multiplication: (x + 1)(x2 + 4x + 3) = x3 + 5x2 + 7x + 3

When multiplying polynomials, the variables' exponents are added, according to the rules of exponents. Remember that the exponents in polynomials are whole numbers. The whole numbers are closed under addition, which guarantees that the new exponents will be whole numbers. Consequently, polynomials are closed under multiplication.

What about division?

Polynomials are NOT closed under division. Look at this simple counterexample:

closure1

When dividing variables with exponents, there is the possibility of creating a negative exponent. Negative exponents are not allowed in polynomials.

Answer:

the y-intercept is 7

Step-by-step explanation:

hope it helps. i just looked at the ordered pair and took the number that's on the y axis

Answer:

y=5x-3

Step-by-step explanation:

Slope intercept form is y=mx+b and you know the slope so you can get y=5x+b

Then you are given a point, (2, 7), so you can plug that into the equation to find the y-intercept

7=5(2)+b

Then you just solve for b

7=10+b

-10

-3=b

So the final equation is y=5x-3

Answer:

yup

Step-by-step explanation:

Answer:

The perimeter of the track is the two circumferences of the semicircles (when combined, they form one circle, so we can just find the circumference of the circle) added to the lengths of the rectangle (160 meters).

To find the circumference of the circle, we need to know the diameter.

Circumference of a circle: dπ or 2rπ, where d represents diameter and r represents radius

The diameter of the circle happens to be the same as the width of the rectangle. We know that the area of a rectangle is found by multiplying its length by its width. We know that the area is 14400 and that its length is 160.

Width: area divided by length

14400160=90

The diameter of the circle and the width of the rectangle is 90 meters.

Circumference:

90⋅π=90π→ If you are using an approximation such as 3.14 for π, multiply that by 90

Add 160⋅2 to the circumference since the lengths of the rectangle are also part of the perimeter.

160⋅2=320

90π+320

Answer:

Supplementary Angle

Step-by-step explanation:

If you add the angles "a" and "b" together you get an angle of 180º.

A supplementary angle is an angle that adds up to 180º.

A complementary angle is an angle that adds up to 90º.

A vertical angle has two lines that intersect (like an "X".
