The hypotenuse of a
right triangle is 10 cm.

One of the side lengths is 8 cm.

What is the length of the other side?

Answer:

w⁴ + 3w³ + 11w² + 6w + 18

Step-by-step explanation:

Rectanle area = height * width

area = (w²+3w+9)(w² + 2)

        = w²*w² + w²*2 + 3w*w² + 3w*2 + 9*w² + 9*2

        = w⁴ + 2w² + 3w³ + 6w + 9w² + 18

        = w⁴+ 3w³ + (9w²+2w²) + 6w + 18

        = w⁴ + 3w³ + 11w² + 6w + 18

Answer:

w^4 + 3w^3 + 11w^2 + 6w + 18.

Step-by-step explanation:

Area = height * width

= (w^2 + 2)(w^2 + 3w + 9)

= w^2(w^2 + 3w + 9) + 2(w^2 + 3w + 9)

= w^4 + 3w^3 + 9w^2 + 2w^2 + 6w + 18

= w^4 + 3w^3 + 11w^2 + 6w + 18.

Answer:

The possible midpoints of AB are 6.5 and 9.5

Step-by-step explanation:

Given that the coordinates of A is 8

The length of AB = 3

When A is the maximum coordinates of the two coordinates, A and B, we have;

The midpoint of AB = Coordinates of A - 1/2 × Length of AB

The midpoint of AB = 8 - 1/2 × 3 = 8 - 1.5 = 6.5

The midpoint of AB = 6.5

When A is the minimum coordinates of the two coordinates, A and B, we have;

The midpoint of AB = Coordinates of A + 1/2 × Length of AB

The midpoint of AB = 8 + 1/2 × 3 = 8 + 1.5 = 9.5

The midpoint of AB = 9.5

Therefore, the possible midpoints of AB are 6.5 and 9.5.

Answer: $18.76

Step-by-step explanation:

Let original cost of meal =x

According to question,

x+20%=18.96

x=18.96-20%

x=$18.76

Answer:

original cost of meal  = $15.80

Step-by-step explanation:

120% = $18.96 (divide both sides by 120)

1% = $0.158  (multiply both sides by 100)

100% = $15.80

Answer:

(14, - 13 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ [tex]\frac{1}{2}[/tex] (x₁ + x₂ ), [tex]\frac{1}{2}[/tex] (y₁ + y₂ ) ]

let (x₁, y₁ ) = (- 2, - 7) and (x₂, y₂ ) = (x, y)

Using the midpoint formulae equate to the coordinates of the midpoint.

[tex]\frac{1}{2}[/tex] (- 2 + x) = 6 ( multiply both sides by 2 )

- 2 + x = 12 ( add 2 to each side )

x = 14

and

[tex]\frac{1}{2}[/tex] (- 7 + y ) = - 10 ( multiply both sides by 2 )

- 7 + y = - 20 ( add 7 to both sides )

y = - 13

Thus

coordinates of other endpoint = (14, - 13 )

Answer:

1. 3 − 6n

2. Melody: m Fatima: 3m

3. i. Perimeter = y + 10 + 8

   ii. The perimeter is 25 inches when y = 7

Step-by-step explanation:

1. Let the number be represented by n, thus the product of  the number and 6 is 6n.  Since 3 is less than 6n, therefore: 3 - 6n is the appropriate expression.

2. Let Melody's age be represented by m, Fatima is three times Melody's age implies 3m. So that Melody's age is m, while Fatima's age is 3m.

3. Length of the sides of the triangle in inches are 10, 8 and y.

Perimeter = addition of the length of sides of the triangle

                = 10 + 8 + y

When y = 7,

Perimeter = 10 + 8 + 7

                 = 25 inches

Answer:

-1/2

Step-by-step explanation:

To find the slope, pick two points on the line, and use the slope formula

( 1,9) and  (5,7)

m = (7-9 )/(5-1)

   -2/4

  -1/2

Answer:

slope = -1/2

Step-by-step explanation:

Find two points on the line that are easy to read. The easiest points to read are points that lie on grid intersections.

For example, use point (1, 9) and point (3, 8).

slope = rise/run

Rise is the vertical distance between points. Up is positive. Down is negative.

Run is the horizontal distance between points. Right is positive. Left is negative.

You need to go from one point to the other points and note the rise and run.

Start at (1, 9).

Go 1 unit down. That is a rise of -1 since you went down 1 unit.

Now go 2 units right. That is a run of +2 since you went 2 units to the right.

slope = rise/run = -1/2

Answer: slope = -1/2

Answer:

4.8 in, 3.125 mi

Step-by-step explanation:

This situation models direct proportionality, hence, if one variable increases, the other goes increases as well and vice versa. In this case, the variables are inches and miles.

Part A: Since you multiply 60/25 by 25 to get 60 miles, we know that the value in inches will be 2 * 60/25 = 4.8 inches.

Part B: Since you divide 2 by 8 to get 1/4 inches, we know that the value in miles will be 25 / 8 = 3.125 miles.

Answer:

f(a+2)=3(a+7)+4/(a+2)

Step-by-step explanation:

To determinef(a+2) you need to substitute a+2 for each occurrence of x in the given function. See below for full explanation.

Explanation:

If

f(x)=3(x+5)+4/x

Then  

f(a+2)=3(a+2+5)+4/a+2

Simplifying gives:

f(a+2)=3(a+7)+4/(a+2)

Answer:

-3 is a rational integer.

Step-by-step explanation:

An integer is a superset of the whole numbers that includes the negated values as well as 0.

A rational number is simply anything that can be expressed as a fraction.

-3 is by these definitions, a negated 3, and any non fractional number can be expressed as a fraction.

-3 is not a natural number, as that is the set of numbers {1, 2, 3, 4, 5, ... etc} and -3 is not a whole number, as that is the set of numbers {0, 1, 2, 3, 4, ... etc}.

And -3 is also not an irrational number since it can be expressed as a fraction.

Thus, -3 is a rational integer.

Cheers.

Answer:

285.28571429 minutes

Step-by-step explanation:

Let us represent

The number of minutes you talk = t

C1 = Cost in dollars of the first plan

C2 = Cost in dollars of the second plan

First plan

The first plan charges a rate of 26 cents per minute

Converting cents to dollars

100 cents = 1 dollars

26 cents =

26/100 cents

=$ 0.26

C1 = $0.26 × t

C1 = 0.26t .......... Equation 1

Second Plan

The second plan charges a monthly fee of $39.95 plus 12 cents per minute

Converting 12 cents to dollars

100 cents = 1 dollars

12 cents =

12/100

= $0.12

C2 = $39.95 + 0.12t........Equation 2

Find the number of talk minutes that would produce the same cost for both plans

We would Equate C1 to C2

C1 = C2

0.26t = $39.95 + 0.12t

Collect like terms

0.26t - 0.12t = $39.95

= 0.14t = $39.95

Divide both sides by 0.14

= t = $34.95/0.14

t = 285.28571429 minutes

Therefore, the number of talk minutes that would produce the same cost for both plans is 285.28571429 minutes.

Answer:

Solution: Option C

Step-by-step explanation:

Our goal here is to factor the expression such that it is converted into the circle equation (x - a)² + (y - b)² = r² where r = radius centered at point (a,b).

[tex]x^2\:+\:y^2\:+8x\:-\:12y\:+\:43\:=\:0[/tex] (Factor the expression "x² + 8x")

[tex]x^2+8x = x\left(x+8\right)[/tex] (Factor the expression "y² - 12y")

[tex]\:y^2-12y =y\left(y-12\right)[/tex]

That leaves us with the expression [tex]\left(x-\left(-4\right)\right)^2+\left(y-6\right)^2=3^2[/tex], or in other words [tex](x+4)^2 +(y-6)^2 = 9[/tex]. As you can see our solution is option c.

Answer:

Amplitude is 0.3; period is 6π

Step-by-step explanation:

The amplitude is |-0.3| = 0.3.

The period and frequency are related through

                   2π

period  =  ----------

                     b

where b is the coefficient of the independent variable; here that coefficient is 1/3.

Thus, the period here is found using b = 1/3:

period = 2π/b, or 2π/(1/3), or 6π

Use the remainder theorem, which says the remainder upon dividing a polynomial [tex]p(x)[/tex] by [tex]x-c[/tex] is exactly [tex]p(c)[/tex]. In this case,

[tex]p(x)=2x^2+2x+1[/tex]

[tex]c=-1[/tex]

[tex]\implies p(c)=2(-1)^2+2(-1)+1=\boxed{1}[/tex]

Answer:

The domain = 1, 3, 5, 7 and the range = 5, 15, 25, and 35

Step-by-step explanation:

The given parameters are;

The life expectancy of a monkey = 15 years

The life expectancy of an African elephant = 35 years

The life expectancy of a beaver = 5 years

The life expectancy of a grizzly bear = 25 years

Therefore, if the  life expectancy of a beaver = X, we have;

The life expectancy of a monkey = 3 × The life expectancy of a beaver = 3·X

The  life expectancy of a beaver = X

The life expectancy of an African elephant = 7 × The life expectancy of a beaver = 7·X

The life expectancy of a grizzly bear = 5 × The life expectancy of a beaver = 5·X

Therefore;

The domain = 1, 3, 5, 7 and the range = 5, 15, 25, and 35.

Answer:

Relation = {(Monkey, 15), (African elephant, 35), (Beaver, 5), (Grizzly bear, 25)}

Domain = {Monkey, African elephant, Beaver, Grizzly bear}

Range = {5, 15, 25, 35}

Step-by-step explanation:

Relation is just (x,y).

{(Monkey, 15), (African elephant, 35), (Beaver, 5), (Grizzly bear, 25)}  

I like to put domain as least ---> greatest, but in this case, it's just the names

{Monkey, African elephant, Beaver, Grizzly bear}

The numbers.

{5, 15, 25, 35}
