Answer:

39

Step-by-step explanation:

to find the area of the triangles use the equation

3(5)(.5)=7.5

since we have 4 triangles, multiply that by 4, which equals 30

Now find the area of the square

3(3)=9

Now add the area of the square and the area of the triangles

Answer:

39 km

Step-by-step explanation:

Surface area=area of square +area of triangles

=3*3 + 0.5*3*5*4

=39

Answer:

7 is the positive whole number which we can multiply by 3 and add 1, or multiply by 2 and add 8; and it will give the same answer.

Step-by-step explanation:

Multiplying the positive whole number 7 by 3 and adding 1 will get:

(7 × 3) + 1 = 21 + 1 = 22

Multiplying the positive whole number 7 by 2 and adding 8 will get:

(7 × 2) + 8 = 14 + 8 = 22

Therefore, 7 is the positive whole number which we can multiply by 3 and add 1, or multiply by 2 and add 8; and it will give the same answer.

Answer: g(x) = (1/3)*(-x)^2 + 3.

Step-by-step explanation:

Let's define all the transformations in a general way,

A vertical contraction/dilation of a scale factor a is written as:

g(x) = a*f(x)

where if a > 1, it is a dilation.

if  0 < a < 1, it is a contraction.

A reflection in the y-axis changes the value of the x-component and leaves the y-component invariable, then this transformation is written as:

g(x) = f(-x).

A translation of A units up (A positive) is written as:

g(x) = f(x) + A.

Then for this case we have:

A dilation with scale factor 1/3.

g(x) = (1/3)*f(x)

A reflection over the y-axis.

g(x) = (1/3)*f(-x)

A translation of 3 units up.

g(x) = (1/3)*f(-x) + 3

(in that order, remember that the order in which you applly the transformations matters)

Then g(x) = (1/3)*f(-x) + 3

and f(x) = x^2, so we can replace that in the equation for g(x)

g(x) = (1/3)*(-x)^2 + 3.

Transformation involves changing the position of a function.

The rule for g is: [tex]\mathbf{g(x) = \frac 13(x - 3)^2}[/tex]

The parent function is given as:

[tex]\mathbf{f(x) = x^2}[/tex]

The rule of vertical shrink by a factor of 1/3 is:

[tex]\mathbf{(x,y) \to (x,\frac 13y)}[/tex]

So, we have:

[tex]\mathbf{f'(x) = \frac 13x^2}[/tex]

The rule of reflection across the y-axis is:

[tex]\mathbf{(x,y) \to (-x,y)}[/tex]

So, we have:

[tex]\mathbf{f''(x) = \frac 13(-x)^2}[/tex]

[tex]\mathbf{f''(x) = \frac 13x^2}[/tex]

The rule of translation 3 units right is:

[tex]\mathbf{(x,y) \to (x - 3,y)}[/tex]

So, we have:

[tex]\mathbf{g(x) = \frac 13(x - 3)^2}[/tex]

Hence, the rule for g is: [tex]\mathbf{g(x) = \frac 13(x - 3)^2}[/tex]

Answer:

[tex]Discount = \$19.98[/tex]

Step-by-step explanation:

Given

[tex]Amount = \$49.95[/tex]

[tex]Price\ Off = 40\%[/tex]

Required

Determine the discount

The discount is calculated by multiplying the price off by the original price:

[tex]Discount = Amount * Price\ Off[/tex]

[tex]Discount = \$49.95 * 40\%[/tex]

Convert % to decimal

[tex]Discount = \$49.95 * 0.40[/tex]

[tex]Discount = \$19.98[/tex]

Hence, the amount of discount is $19.98

Answer:

a or 1. $40,000 is the down payment

b or 2. 180 months = 15 years

c or 3. $168,400 is the left over payment (including mortgage)

d or 4. $935.56 (the monthly payment)

Step-by-step explanation:

1. To calculate the down payment, we need to calculate 20% of $200,000.

200,000 x 0.20  = $40,000

Therefore, the down payment on the home costs $40,000.

2. Now, let's figure out how many months are in 15 years.

15 x 12 = 180

So, the mortgage will be paid in 180 months.

3. Next, we need to find out how much money needs to be paid in the 15 years.

200,000 - 40,000 = $160,000

This price will also include an annual interest rate of 5.25%. So, we need to find 5.25% of $160,000.

160,000 x 0.0525 = $8,400 <--- interest rate when rounded to the nearest cent.

160,000 + 8,400 = $168,400 <--- total amount over 15 years

4. To find the monthly payment, we must divide the total amount of money ( or  $168,400), by the number of months, (or 180.)

$168,400 ÷ 180 = $935.56 when rounded to the nearest cent.

Answer:

[tex]Probability = \frac{1}{969}[/tex]

Step-by-step explanation:

Given

[tex]Members = 19[/tex]

[tex]Selection = 3[/tex]

Required

Determine the probability of selecting Jim, Bruce and Valerie

First, we need to calculate the possible number of selections.

This is calculated using combination formula:

[tex]Selection = ^nC_r[/tex]

[tex]Selection = ^{19}C_3[/tex]

[tex]Selection = \frac{19!}{(19-3)!3!}[/tex]

[tex]Selection = \frac{19!}{16!3!}[/tex]

[tex]Selection = \frac{19 * 18 * 17 * 16!}{16! * 3 * 2 * 1}[/tex]

[tex]Selection = \frac{19 * 18 * 17}{3 * 2 * 1}[/tex]

[tex]Selection = \frac{19 * 18 * 17}{6}[/tex]

[tex]Selection = 969[/tex]

Selection of Jim, Bruce and Valerie is only 1 selection of the 960 possible selection.

So:

[tex]Probability = \frac{1}{969}[/tex]

The probability that Jim, Bruce, and Valerie are selected in any​ order is [tex]\rm P=\dfrac{1}{969}[/tex] and this can be determined by using the given data.

Given :

Assume that Jim, Bruce, and Valerie are three of the 19 members of the​ class and that three of the class members will be chosen randomly to deliver their reports during the next class meeting.

In order to determine the probability that Jim, Bruce, and Valerie are selected in any​ order, first determine the total number of possible selections.

The total number of possible selections is given by:

[tex]\rm S = \; ^nC_r[/tex]

[tex]\rm S = \; ^{19}C_3[/tex]

[tex]\rm S = \dfrac{19!}{16! \times 3!}[/tex]

S = 969

So, the probability that Jim, Bruce, and Valerie are selected in any​ order is:

[tex]\rm P=\dfrac{1}{969}[/tex]

Answer:

Slope=1

Step-by-step explanation:

Slope=y1-y2/x1-x2

Where x1,y1= (1, 1) and X2,y2=(-3, -3)

Slop=1+3/1+4

=4/4

=1

So the slope is 1.

Answer:

1

Step-by-step explanation:

Here,

x₁ = 1 and x₂ = (-3)

y₁ = 1 and y₂ = (-3)

Now,

Slope

= y₁ - y₂ ÷ x₁ - x₂

= ( 1 ) - (- 3) ÷ ( 1 ) - (- 3)

= 1 + 3 ÷ 1 + 3

= 4 ÷ 4 = 1

Thus, Slope is 1

Answer: 7 years

Step-by-step explanation:

Let t be the number of periods in which geese doubles .

The exponential growth function:[tex]y=Ab^t[/tex] , where A = initial value , b= growth factor.

As per given , A = 5 , b=2

i.e. Number of geese after t periods = [tex]y=5(2)^t[/tex]

Put y=111, we get

[tex]111=5(2)^t\\\\\Rightarrow\ \dfrac{111}{5}=2^t\\\\\Rightarrow\ 22.2=2^t[/tex]

Taking log on both sides , we get

[tex]\log 22.2 = t\log 2\\\\\Rightarrow\ 1.346353=t(0.30103)\\\\\Rightarrow\ t=\dfrac{1.346353}{0.30102}\\\\\Rightarrow\ t=4.47263636\approx4.47[/tex]

Now , total months = 4.47 x 18 =80.46≈ 80 months

since 1 year =12 months

Number of years it will take [tex]=\dfrac{80}{12}=\dfrac{20}{3}=6.66666666667\approx7[/tex]

Hence, it will take 7 years (approx.)

Answer: the larger number is 54

Step-by-step explanation:

x + y = 56

xy = 108

x = 56 - y

substitute the x value in equation

(56 -y) y = 108

56y - y^2 = 108

y^2 - 56y + 108 = 0

=(y - 2)(y - 54)

The two numbers are 2 and 54.

Multiplication is the process of adding a number up to a given number.

Given that, the sum of the two numbers is 56 and their product is 108.

Let the numbers are x and y then,

x + y = 56    (1)

xy = 108

x = 108/y

Substitute x = 108/y into equation (1):

108/y + y = 56

108 + y² = 56y

y² -56y + 108 = 0

y² -54y -2y + 108 =0

y(y - 54) -2(y - 54) = 0

(y - 2)(y - 54) = 0

y =2 or y = 54

Now, for y = 2 the value of x is 54 and for y = 54 the value of x is 2.

Hence, the two numbers are 2 and 54.

Answer:

S(-2, -3)

Step-by-step explanation:

Find the diagram attached below,=. Frim the diagram, the coordinate of R and T are (-5, 3) and (-1, -5) respectively. If the ratio of RS to ST is 3:1, the coordinate of S can be gotten using the midpoint segment formula as shown;

S(X, Y) = {(ax1+bx2/a+b), (ay1+by1/a+b)} where;

x1 = -5, y1 = 3, x2 = -1, y2 = -5, a = 3 and b =1

Substitute the values into the formula;

X = ax2+bx1/a+b

X = 3(-1)+1(-5)/3+1

X = -3-5/4

X = -8/4

X = -2

Similarly;

Y = ay2+by1/a+b

Y = 3(-5)+1(3)/3+1

Y = -15+3/4

Y = -12/4

Y = -3

Hence the coordinate of the point (X, Y) is (-2, -3)

Answer:

Mean: 8 free throws

Standard Deviation: 1.3 free throws

Step-by-step explanation:

This is a binomial random variable, so we can use the formula [tex]ux = np[/tex], where n is the number of trials, and p is the probability. Since we know both of these values, just plug it in for the mean. [tex]ux = .8*10 = 8[/tex]

For the standard deviation, we use the formula σ = [tex]\sqrt{np(1-p)}[/tex]. Since we know what np is, we can replace those 2, giving us [tex]\sqrt{8(1-p)}[/tex]. Again, p is our probability, so this gives us our final equation of [tex]\sqrt{8(1-.8)}[/tex], which simplifies to [tex]\sqrt{8(.2)}[/tex]. Using a calculator, we get 1.264, which is 1.3 rounded to the nearest tenth.
