Jennifer’s bank account is modeled by the following equation where x equals the number of weeks and f(x) equals the total balance.

f(x) = 12x + 45

The balance of William’s bank account is modeled in the table.

Weeks 0 1 2 3 4
Total Balance ($) 30 44 58 72 86


Part A
What function represents the balance of William’s bank account?

g(x) = 14x + 30

g(x) = 30x

g(x) = 30x + 14

g(x) = 14x

Part B
Jennifer claims that her bank account is growing at a greater rate of change than William’s bank account. Is Jennifer CORRECT?

No, because her rate of change is $ 45 per week which is less than William’s rate of change.

Yes, because her rate of change is $ 12 per week which is more than William’s rate of change.

Yes, because her rate of change is $ 45 per week which is more than William’s rate of change.

No, because her rate of change is $ 12 per week which is less than William’s rate of change.

If a clock shows the hour hand between 6 and 7 and the minute hand at 10. It means : D.50 minutes after 6, E. 6:50

Each of the section time of an analog clock is 5 minutes. Since the hour hand is between 6 and 7 and the minute hand is on 10 ,  it implies that :

The interest on principle $775 over eight year at rate 1.47% is  $91.14

Simple interest is a interest which is only based on principle amount, it does not imply on yearly interest.

The given principle, p = $775 ,

Rate r = 1.47 %,

and Time = 8 year.

To find interest I, Use formula,

I=(p × r × t)/100,

I=775 ×1.47 ×8/100,

I = $91.14

So the interest is I = $91.14

a) The distance travelled on the cycle in the first 14 seconds is; 96 m

b) The acceleration in the first 4 seconds is; 2 m/s²

The velocity time graph for a cycle is as attached.

The distance covered will be the area under the curve.

Formula for area of trapezium is;

A = (1/2)(sum of parallel sides) * height

Area for 0 to 14 sec is a trapezium formed with parallel sides as 14 and  10 while distance between them is 8 is solved as;

Area = (1/2)(14 + 10) * 8  

Area = 24 * 4  = 96  

Thus;

Distance covered = 96 m

Distance travelled on the cycle in the first 14 seconds is 96 m.

Therefore, the acceleration in first 4 seconds = (8 - 0)/(4 - 0)

= 8/4 = 2 m/s²

The Domain is R i.e all real numbers and the range is [-16,∞).

What is the domain and range of function?

A function's domain and range are its components. A function's range is its potential output; its domain is the set of all conceivable input values. Domain, Function, and Range. If a function f: A B exists that maps every element in A to an element in B, then A is the domain and B is the co-domain. The image of an element 'a' under a relation R is provided by 'b,' where (a,b) R. The set of photographs makes up the function's range.

f(x)=x²-4x-12  

For Domain it can take all the real numbers as there is no term in the denominator. so Domain is "R"

Range will be f(x) is minimum at x = 2 i.e. f(x=2) = -16

They are congruent by SAS as follows if I understand you correctly:

Since x is shared by both NR and AG, it must be at their intersection.

Because it lies in the middle of both, NX = XR and AX = XG.

We join point A to point N and point R to point G to complete the triangles (any 2 points define a line).

Due to the fact that there are two triangles on either side of the point X, angle AXN is perpendicular to angle RXG. Angle AXN is equal to angle RXG because the vertical (opposite) angles formed by two intersecting lines are equal.

The following is how the SAS evidence of congruency is established:

Angle RXG in triangle RXG and angle AXN in triangle AXN are congruent (vertical angles)

Triangles AX in AXN and XG in RXG are congruent (midpoint X of line AG created these).

Triangle RXG and triangle AXN's NX and XR are congruent.

By SAS, triangles are congruent. this means they have two corresponding sides that are congruent and the angle between those 2 corresponding sides is congruent also.

Answer:

m = - 3

Step-by-step explanation:

since the line passes through (1, 3 ) then the coordinates of the point make the equation true.

substitute x = 1, y = 3 into the equation and solve for m

3 = m + 6 ( subtract 6 from both sides )

- 3 = m

The measurement of m∠1 and m∠3 is 52° when a is parallel to b.

According to the question,

We have the following information:

The line a is parallel to b and they are being cut a line m.

m∠6 = 128°

We know that when two parallel lines are cut by another line then the sum of consecutive interior angles is 180°. And we also know that vertically opposite angles are equal.

m∠1 and m∠3 are vertically opposite angles.

m∠3 and m∠6 are consecutive interior angles.

∠3+∠6 = 180°

∠3 = 180-128

∠3 = 52°

So, we have:

∠1 = ∠3 = 52°

Hence, the measurement of m∠1 and m∠3 is 52° when a is parallel to b.

The half life of the substance is 828.37

The period of time it takes for one-half of a radioactive isotope to decay is known as the half-life. An individual radioactive isotope's half-life is unaffected by environmental factors and is independent of the isotope's starting concentration.

The amount of time needed for half of a radioactive sample's atomic nuclei to decay

Given:

As, The amount of a substance after t days is given by:

p(t)= [tex]p(0)[/tex][tex]e^{-kt[/tex]

Original amount after 300 days.

p(300)= 0.778p(0).

p(t)= [tex]p(0)[/tex][tex]e^{-kt[/tex]

0.778 = p(0)[tex]e^{-300k[/tex]

-300k= log (0.778)

-300k= -0.109020

k = 0.0003634

So, p(t)= [tex]p(0)[/tex][tex]e^{-0.0003634t[/tex]

This is t for which P(t) = 0.5P(0). So

0.5p(0)=  [tex]p(0)[/tex][tex]e^{-0.0003634t[/tex]

[tex]e^{-0.0003634t[/tex] = 0.5

log ( [tex]e^{-0.0003634t[/tex]) = log 0.5

-0.0003634 t = log 0.5

Answer:

  m∠6 = 61°

Step-by-step explanation:

Given a transversal crossing parallel lines AB and CD, you want the measure of angle 6 given that angle 2 is 61°.

Where a transversal crosses parallel lines, corresponding angles and vertical angles are congruent. This has the effect of making all acute angles congruent, and all obtuse angles congruent.

Acute angle 6 is congruent to acute angle 2, which measures 61°. (They are "corresponding" angles.)
