Ms. Field counts chapter tests as 40% of a student’s grade, homework as
20%, quizzes, and classwork as 20%, and final exams at 20%. Lydia has an
average of 89 before the final. What score must she get correct on the
final to bring her grade up to 90?

Answer:

Here we are given with a graph.

we have been asked to find the value of x for which

As we know that , to find the value of x for the given value of f(x), we need to look onto the vertical axis, and mark a dot on the given value now draw a line perpendicular to vertical axis so that it cut the given straight line, and where they intersect draw another line perpendicular to the horizontal axis and you will get the value where it crosses the horizontal axis.

We get x=5, then f(x)=7.

Answer:

f(x)=23/8

Step-by-step explanation:

To find horizontal asymptotes: If the degree (the largest exponent) of the denominator is bigger than the degree of the numerator, the horizontal asymptote is the x-axis (y = 0). If the degree of the numerator is bigger than the denominator, there is no horizontal asymptote.

Answer:

3+.8+.02+.005

Step-by-step explanation:

In expanded form, 3.825 equals 3 + 0.8 + 0.02 + 0.005. In math, expanded form is useful because it allows us to look at a number and determine the value of each digit.

Therefore,

Expanded Form of 3.825

3.825 = (3 × 100) + (8 × 1/101) + (2 × 1/102) + (5 × 1/103)

3.825 = (3 × 1) + (8 × 1/10) + (2 × 1/100) + (5 × 1/1,000)

3.825 = 3 + 8/10 + 2/100 + 5/1,000

Simplifying the above equation, then we get,

3.825 = 3 + 0.8 + 0.02 + 0.005.

Hence, In expanded form, 3.825 equals 3 + 0.8 + 0.02 + 0.005.

Answer:

The correct answer is D, 5

Step-by-step explanation:

If the table represents a proportional relationship between our values x and y, we can find our function.

From our constants in x, the increase is a product of x by 5 to result in y's value. Therefore, the constant unit rate of y per x is 5.

Answer:

x=45

Step-by-step explanation:

you would change it to 90-x=x because the angles are congruent and then add x on both sides until it is 90=2x, divide 2 from both sides to get 45=x

Answer:

$52

Step-by-step explanation:

32.50/5=6.50

1 costs $6.50

8x6.50=$52

Answer:

$52 dollars because you have to find the original number which is what is 1 box equal to which is $6.50 then you multiply $6.50 by 8 and get $52

Answer:

[tex]m = \frac{4}{3}[/tex] ---- Slope of LK

[tex]m = -\frac{3}{5}[/tex] ---- Slope of LM

[tex]D = 5[/tex] ---- Length of LK

[tex]D = \sqrt{34}[/tex] --- Length of LM

Anthony is incorrect

Step-by-step explanation:

See attachment for complete question.

From the attachment, we have:

[tex]K = (-4,8)[/tex]

[tex]L = (-7,4)[/tex]

[tex]M = (-2,1)[/tex]

Solving (a): Slope of LK

Slope (m) is calculated as thus:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Where

[tex](x_1,y_1) = (-4,8)[/tex] ----- K

[tex](x_2,y_2) = (-7,4)[/tex] ------ L

[tex]m = \frac{4 - 8}{-7 - (-4)}[/tex]

[tex]m = \frac{4 - 8}{-7 +4}[/tex]

[tex]m = \frac{-4}{-3}[/tex]

[tex]m = \frac{4}{3}[/tex]

Slope of LM

Slope (m) is calculated as thus:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Where

[tex](x_1,y_1) = (-7,4)[/tex] ---- L

[tex](x_2,y_2) = (-2,1)[/tex] ------ M

[tex]m = \frac{1 - 4}{-2 - (-7)}[/tex]

[tex]m = \frac{1 - 4}{-2 +7}[/tex]

[tex]m = \frac{-3}{5}[/tex]

[tex]m = -\frac{3}{5}[/tex]

Solving (b): Length of LK and LM

Here, we have to calculate the length using distance formula;

Distance (D) is calculated as thus:

[tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

For LK

[tex](x_1,y_1) = (-4,8)[/tex] ----- K

[tex](x_2,y_2) = (-7,4)[/tex] ------ L

[tex]D = \sqrt{(-7 - (-4))^2 + (4 - 8)^2}[/tex]

[tex]D = \sqrt{(-7 +4)^2 + (4 - 8)^2}[/tex]

[tex]D = \sqrt{(-3)^2 + (-4)^2}[/tex]

[tex]D = \sqrt{9 + 16}[/tex]

[tex]D = \sqrt{25}[/tex]

[tex]D = 5[/tex]

For LM

[tex](x_1,y_1) = (-7,4)[/tex] ---- L

[tex](x_2,y_2) = (-2,1)[/tex] ------ M

[tex]D = \sqrt{(-2 - (-7))^2 + (1 - 4)^2}[/tex]

[tex]D = \sqrt{(-2 +7)^2 + (1 - 4)^2}[/tex]

[tex]D = \sqrt{(5)^2 + (-3)^2}[/tex]

[tex]D = \sqrt{25 + 9}[/tex]

[tex]D = \sqrt{34}[/tex]

[tex]D = 5.83[/tex]

The above findings is not enough to conclude if Anthony is correct or incorrect.

We need to calculate the distance of KM using the same formula;

[tex](x_1,y_1) = (-4,8)[/tex] ----- K

[tex](x_2,y_2) = (-2,1)[/tex] ------ M

D is calculated as thus:

[tex]D = \sqrt{(-2 - (-4))^2 + (1 - 8)^2}[/tex]

[tex]D = \sqrt{(-2 +4)^2 + (-7)^2}[/tex]

[tex]D = \sqrt{(2)^2 + (-7)^2}[/tex]

[tex]D = \sqrt{4 + 49}[/tex]

[tex]D = \sqrt{53}[/tex]

Base on this, we can conclude that Anthony's claim is incorrect.

6 boxes, 3 books

Step-by-step explanation:

Samantha has 45 books

She can pack 7 books in each box

The number of box she can completely fill can be calculated as follows

[tex]y = 5 - 2x[/tex]

i think this is the answer

Step-by-step explanation:

ω = ω₀ + αt

θ = ω₀ t + ½ αt²

We need to eliminate t from the system of equations.  Solve for t in the first equation, then substitute it into the second equation.

t = (ω − ω₀) / α

θ = ω₀ (ω − ω₀) / α + ½ α ((ω − ω₀) / α)²

θ = ω₀ (ω − ω₀) / α + ½ (ω − ω₀)² / α

αθ = ω₀ (ω − ω₀) + ½ (ω − ω₀)²

αθ = ω₀ω − ω₀² + ½ (ω² − 2ω₀ω + ω₀²)

αθ = ω₀ω − ω₀² + ½ ω² − ω₀ω + ½ ω₀²

αθ = ½ ω² − ½ ω₀²

2αθ = ω² − ω₀²

Answer:

heres an example: Replace all x's in

g(x)

with the function f(x) to get

g(f·x)=(x+3)2

Explanation:

g(f·x)

means that you replace all x's in

g(x)

with the function

(f·x)

The easiest way to do this is rewrite

g(x)

replacing all x's with a blank set of parenthesis, like this

-g(f·x)=(x)2

Now place the function into the parenthesis.

(f·x)

g(f·x)=(x+3)2
