Question 11

The slope is 7/2 (so the line is increasing), and the y-intercept is 3.

Question 12

The slope is -8/3 (so the line is decreasing), and the y-intercept is -5.

Answer:

Number above 42 : 14

Number beside 2 : 1

Number above 0: 12

Step-by-step explanation:

The shaded sections of the trapezoid are triangles.

We know how to find the area of triangles

A = 1/2 bh

Lets start with the left triangle

The bases is 1.1 inches and the height is 3.8 inches

A left triangle is

A = 1/2 ( 1.1) * 3.8 = 2.09

The right triangle has the same dimensions

A right triangle is

A = 1/2 ( 1.1) * 3.8 = 2.09

Add the two triangles together

2.09+2.09 = 4.18 in^2

The area of the shaded region is 4.18 in^2

We can see here, from the first term to the second term, we minus 2. From the second term to the third term, we minus 2.

So, we're constantly reducing by an amount, therefore making this sequence an arithmetic sequence.

The common difference, said above, is -2 (since if the terms are getting smaller the common difference is a negative number.)

If r = -6,  s = -2, v = 10 and w = 3, then the response of the expression vs(r-s) ÷ 2 + rw is option (D) 22

The expression is

vs(r-s) ÷ 2 + rw

The values are

r = -6

s = -2

v = 10

w = 3

Substitute the values in the given expression

= 10×-2 (-6-(-2)) ÷ 2 + -6×3

First we have to do the arithmetic operation in brackets

= 10 × -2 (-4) ÷ 2 + -6×3

Next we have to do the multiplications

= 80 ÷ 2 -18

Do the division

= 40-18

= 22

Hence, if r = -6,  s = -2, v = 10 and w = 3, then the response of the expression vs(r-s) ÷ 2 + rw is option (D) 22

Explanation:

The balance after t years can be calculated using the following equation:

Where P is the principal amount and r is the rate of interest per year.

So, replacing P by $300, r by 3.5%, and t by 5, we get:

So, the balance after 5 years is $356,3059

Answer: $356.3059

Santiago needs to invest  50467.3 dollars for the value of the account to reach $81,000 in 16 years at a rate of 3.3%.

Simple interest is often a predetermined percentage of the principle amount borrowed or lent paid or received over a specific time period.

Borrowers are required to pay interest on interest in addition to principal since compound interest accrues and is added to the accrued interest from prior periods.

Given Santiago is going to invest in an account paying an interest rate of 3.3% compounded annually for the value of the account to reach $81,000 in 16 years.

We know the formula of compound interest which is A = P(1 + r/100)ⁿ,

where A = Amount, P = Principle, n = Time in years and r = rate percentage.

∴ 81000 = P( 1 + 3.3/100)¹⁶.

81000 = P( 1 + 0.03)¹⁶.

81000 = P( 1.03)¹⁶.

81000 = P×1.605.

P = 81000/1.605

P = 50467.3 dollars.

Answer:

The limit from the left does not equal the limit from the right.

The area of the triangle is 18 cm.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

In Triangle ABC,

AB= 6cm

AC= 8cm

BC= 12cm.

Angle ACB= 26.4

The area of a triangle is given as:

Area = 1/2 x base x height

From the figure below,

Base = BC = 12

D is the midpoint of BC.

BC = BD + DC

DC = 12/2 = 6

Height = Tan 26.4

Tan 26.4 = AD / DC = AD / 6

0.50 = AD / 6

AD = 0.50 x 6

AD = 3

Now,

Area of the triangle ABC:

= 1/2 x base x height

= 1/2 x 12 x 3

= 18 cm

Thus,

The area of the triangle is 18 cm.

Answer:

Step-by-step explanation:

According to quadratic formula:

y = - b  ±  √ b²- 4ac / 2a

y = - (-5) ± √ -5²- 4(2x-12) / 2(2)

y = 5 ± √ 25 - 4(-24) / 4

y = 5 ± √ 25 - (-96) / 4

y = 5 ± √ 121 / 4

y = 5 ± √ (11)² / 4

y = 5 ± 11 / 4

Now either,

y = 5 + 11 / 4

y = 4

Or,

y = 5 - 11 / 4

y = -3/2 = -1.5

Equation

Steps

1. Group the variables and constants on each side of the equality

2. Operate the variables and operate the constants.

3. Divide both parts by 4 to clear y

Given that a polynomial function [tex]f(x)[/tex] has,

And we need to find [tex]f(x)[/tex]

as we know that if a polynomial has zeroes as [tex]\alpha[/tex] , [tex]\beta[/tex] and [tex]\gamma[/tex] , then the cubic polynomial is given by,

[tex]\longrightarrow f(x)=k (x-\alpha)(x-\beta)(x-\gamma)\\ [/tex]

where ,

Now substitute the given zeroes, as ;

[tex]\longrightarrow f(x)=2[ (x-2)(x-\sqrt3)(x+\sqrt3)]\\ [/tex]

[tex]\longrightarrow f(x)= 2[(x-2)\{ x^2-(\sqrt3)^2\}][/tex]

[tex]\longrightarrow f(x)= 2[ x^3-3x -2x^2+6]\\ [/tex]

[tex]\longrightarrow \underline{\underline{ f(x)= 2x^3-4x^2-6x+12}}[/tex]

and we are done!

Answer:

[tex]f(x)=2x^3-4x^2-6x+12[/tex]

Step-by-step explanation:

Given characteristics of the polynomial:

As the polynomial has 3 roots, it is a cubic polynomial.

[tex]\boxed{\begin{minipage}{6 cm}\underline{Intercept form of a cubic polynomial}\\\\$y=a(x-r_1)(x-r_2)(x-r_3)$\\\\where:\\ \phantom{ww}$\bullet$ $r_n$ are the roots. \\ \phantom{ww}$\bullet$ $a$ is the leading constant.\\\end{minipage}}[/tex]

The minimum number of balls that must be chosen randomly from the box to ensure that we get 9 balls of the same color is 39.

Given that a box contains 6 red, 8 green, 10 blue, 12 yellow, and 15 white balls.

As the question says that the minimum number of balls chosen must ensure that we get 9 balls of the same color, so we must consider the balls of those colors which are more than 9 in number.

Here, 10 blue, 12 yellow, and 15 white balls are considered as they are more than 9.

By applying the Pigeon principle,

we can get.,

9 blue + 9 yellow + 9 white – 3 + 1 = 25

As we are picking randomly so we can get all the red and green balls before the above 25 balls.

Therefore we add the balls 6 red + 8 green + 25 = 39

Hence, the minimum number of balls that must be chosen randomly from the box to ensure that we get 9 balls of the same color is 39.
