Find the composition of transformations that map ABCD to EHGF. Reflect over the -axis, then translate (x+ ,y+)

Answers

Answer 1

9514 1404 393

Answer:

(x+ (-4), y+ (-4))

Step-by-step explanation:

After point D is reflected across the y-axis, its coordinates are ...

D(-1, 2) ⇒ D'(1, 2)

This is the point that gets translated to F(-3, -2). The translation is ...

F -D' = (-3, -2) -(1, 2) = (-3-1, -2-2) = (-4, -4)

Then the translation rule is ...

(x, y) ⇒ (x+(-4), y+(-4))

(-4x - 7.5 = 3312.5) + (4x + 4y = 2000)

(please im in a test rn)

Answers

Answer:

y= 1330

Step-by-step explanation:

it might be wrong but

-4x -7.5 = 3312.5

4x +4y = 2000 (x cancels out)

4y -7.5 = 5312.5

4y = 5320

y= 1330

Let f(x)=18/1+3^e-0.1x What is the point of maximum growth rate for the logistic function f(x)? Show all work. Round your answer to the nearest hundredth

Answers

Answer:

(0, 4.5)

Step-by-step explanation:

*The equation can be put into Desmos, to find the point, but the work to prove it is here*

f(x)=c/1+Ae^-Bx

Y=C

C=18 A=3 -B=-0.1

*Replace x with 0 in the equation, so you know 0 is the x value, and it leads you to the y value*

f(0)=18/1+3e^-o.1(0)

= 18/1+3e^0

=18/1+3(1)

=18/1+3

=18/4

=4.5

x=0 y=4.5

Maximum growth rate = (x,y) --> (0, 4.5)

Hope this helps:))!!

Members of a soccer team raised $1719 to go to a tournament. They rented a bus for
$1051.50 and budgeted $44.50 per player for meals. Write and solve an equation
which can be used to determine z, the number of players the team can bring to the
tournament.

Answers

Answer:

44.5x + 1051.5 = 1719

x = 15

Step-by-step explanation:

DeltaMath

The number of players the team can bring to the tournament is 15.

Given:

The total amount of money raised by the soccer team = $1719

Amount to rent the bus = $1051.50

Amount budgeted for each player's meal = $44.50

To find:

Equation and the number of players the team can bring to the tournament

Solution:

The number of players the team can bring to the tournament = z

Amount budgeted for each player's meal = $44.50

Total amount needed for z number of players' meals = $44.50z

Amount to rent the bus = $1051.50

The total amount of money raised by the soccer team = $1719

The equation for numbers of players will be written as:

[tex]\$44.50z+ \$1051.50= \$1719\\\$44.50z= \$1719- \$1051.50\\\$44.50z=\$667.50\\z=\frac{\$667.50}{\$44.50}=15[/tex]

The number of players the team can bring to the tournament is 15.

What is the surface area

Answers

Answer:

red) area = 59.2 km²

Step-by-step explanation:

area of bottom 4 x 4 = 16

area of 4 sides = 4 (1/2)(4)(5.4) = 43.2

16 + 432 = 59.2 km²

Answer:

Step-by-step explanation:

lateral area = 2(base)(slant height) = 2·4·2 = 16 km²

base area = base² = 4² = 16 km²

surface area = 16 + 16 = 32 km²

The graph of y = 4x2 - 4x – 1 is shown.
Use the graph to find estimates for

ii) 4x2 - 4x - 1 = 2

Answers

Answer:

i) The approximate solutions are: [tex]x_{1} \approx -0.207[/tex], [tex]x_{2} \approx 1.207[/tex].

ii) The approximate solutions are: [tex]x_{1}\approx -0.5[/tex], [tex]x_{2} \approx 1.5[/tex].

Step-by-step explanation:

i) The best approach to estimate graphically the solution of [tex]4\cdot x^{2} - 4\cdot x - 1 = 0[/tex] is graphing the following system of equations:

[tex]y = 4\cdot x^{2}-4\cdot x - 1[/tex] (1)

Answers

Answer:

the slope is POSITIVE (answer A)

Step-by-step explanation:

The line goes through: (-1, -2) and ( 2, 1)

Then the slope can be calculated as:

slope = (y2 - y1) / (x2 - x1)

in our case:

slope = (1 - -2) / (2 - -1) = (1 + 2) / (2 + 1) = 3 / 3 = 1

Therefore, the slope is POSITIVE (answer A)

Factor the expression using the GCF. 58+28=

Answers

Answer:

2(29+14)

Step-by-step explanation:

Given function:

To find the GCF of 58+28..

Find the GCF of 58+28:

[tex]58=29[/tex]·[tex]2[/tex] [tex]28=14[/tex]·[tex]2[/tex]

Rewrite:

[tex]2(29+14)[/tex]

Therefore, using GCF, the new expression would be 2(29+14)..

The expression 58 + 28 can be factorized as 2 (29 + 14).

What is GCF?

GCF which is the abbreviated form for Greatest Common Factor of two numbers, as the name implies, is the greatest common factor of both the numbers.

GCF of two numbers can be found using prime factorization.

Given the expression 58 + 28.

To find the GCF of two numbers, list the prime factors of these two numbers.

58 = 2 × 29

28 = 2 × 14 = 2 × 2 × 7

The only common factor is 2.

So the greatest common factor is 2.

58 + 28 = (2 × 29) + (2 × 14)

Taking the common factor of 2 outside the brackets,

58 + 28 = 2 (29 + 14)

Hence the expression 58 + 28 can be factorized as 2 (29 + 14) using the greatest common factor.
