Step-by-step explanation:

Answer:The question is a little incorrect, the ice sheet thickness should be 2m and not 222m.

The required function formula is,

S(t) = 2 - 0.25 t

Step-by-step explanation:

Here, the initial thickness of the ice sheet = 2 meters,

After 3 weeks, the thickness of ice sheet = 1.25 meters

Total changes in the thickness in 3 weeks = 2 - 1.25 = 0.75 meters,

⇒ Total changes in the thickness in 1 weeks = 0.75/3 = 0.25 meters,

Since, the ice is melting with the constant rate.

⇒ The rate of ice decreasing = 0.25 meters per week.

⇒ Total changes in t weeks = 0.25 t meters

The new thickness of ice after t weeks = Initial thickness - Total changes in t weeks.

⇒ S(t) = 2 - 0.25 t

Which is the required function's formula.

Answer:

a) Upwards

b) x = -1

c) (-1,-9)

d) x intercepts; (2,0) and (-4,0)

y intercept is (0,-8)

Step-by-step explanation:

a) As we can see, the parabola faces upwards

b) To find the axis of symmetry equation, we look at the plot of the graph and see the point through the vertex of the parabola that exactly divides the parabola into two equal parts

The x-value that the line passes through here is the point x = -1 and that is the equation of the axis of symmetry

c) The vertex represents the lowest point of the circle here,

As we can see, this is the point through which the axis of symmetry passes through to make a symmetrical division of the parabola

We have the coordinates of this point as

(-1,-9)

d) The intercepts

The x-intercept are the two points in which the parabola crosses the x-axis

We have this point as 2 and -4

The x-intercepts are at the points (2,0) and (-4,0)

For the y-intercept; it is the y-coordinate of the point at which the parabola crosses the y-axis and this is the point (0,-8)

Step-by-step explanation:

change the directions i think

you have to make the -1 -> 0

you have to multiply by -1

and if you multiply the direction will change

Answer:

Step-by-step explanation:

f(0) = -2

f(1) = 3*(f(1 - 1)) -  2*1

f(1) = 3(-2) - 2

f(1) = - 6 - 2

f(1) = - 8

f(2) = 3*(f(1)) - 2*2

f(2) = 3*(-8) - 4

f(2) = -24 - 4

f(2) = - 28

f(3) = 3*(f(2)) - 2*3

f(3) = 3*-28 - 6

f(3) = -84-6

f(3) = - 90

f(4) = 3*f(3) - 2 * 4

f(4) = 3*-90 - 8

f(4) = -270 - 8

f(4) = -278

Answer: 1875

Step-by-step explanation:

The nth term of a geometric progression is given as:

= ar^n-1

Given a = 3 ; r = 5, the nth term will be:

= ar^n-1

= 3 × 5^n-1

The fifth term will be:

= 3 × 5^n-1

= 3 × 5^5-1

= 3 × 5⁴

= 3 × 625

= 1875

The fifth term is 1875

Answer:

A) $7,833.32

Step-by-step explanation:

Given data

Principal= $4,571

Rate=3%

n= 6

Time = 18 years

The expression for compound interest is

A=P(1+r/n)^nt

substitute

A= 4571(1+0.03/6)^6*18

A= 4571(1+0.03/6)^6*18

A= 4571(1+0.005)^6*18

A= 4571(1.005)^6*18

A= 4571(1.005)^108

A=4571*1.7136

A=$7832.86

Hence the approximate amount is A) $7,833.32

Step-by-step explanation:

im not completely sure though so please dont get mad if its wrong

Answer:

No

Step-by-step explanation:

No, (-5, -4) is not a solution to the system of equations. In order for a point to be a solution to a system of equations, the lines have to intersect at that point in a graph. Looking at the given graph, the lines do not intersect at (-5, -4), but at (-4, -5) instead. Thus, (-5, -4) is not a solution.

Answer:

C

Step-by-step explanation:

3/4+3/4=6/4=1 2/4=1 1/2

C is located halfway between 1 and 2, so you know it is 1 1/2.

A fraction is a way to describe a part of a whole.  The number on the number line is represented by point C.

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

To plot the fraction on the number line, the sum of the number line is needed to be found. Therefore, the sum of the number line can be written as,

[tex]\rm Sum = \dfrac34 + \dfrac34 = \dfrac64[/tex]

Thus, the sum of the fraction is (6/4), which can also be written as 1.50.

The number on the number line is represented by point C.
