Answer:

g(x) = 3x best describes Jane's savings in the long run and

f(x) = 3x+3 Mariah's savings in the long run

Step-by-step explanation:

Jane's savings

x ( years ) g(x) = 3x

1 , 3 ...... g(1) = 3 *1 = 3

2 , 6 ........... g(2) = 3 *2 = 6 -> Values missing in the table

3 , 9 ................. g(3) = 3 * 3 = 9

Mariah's savings

x ( years ) f(x) = 3x + 3

1 , 6 ............. f(1) = 3(1) + 3 = 6

2 , 9 ................ f(2) = 3(2) + 3 = 9

3 , 12 .............. f(3) = 3(3) + 3 = 12

What percent of 60 is 12? Show your work.

Semmy [17]

Percent formula : is/of = %/100
is = 12
of = 60
% = x
now we sub

12/60 = x/100
cross multiply
(60)(x) = (12)(100)
60x = 1200
x = 1200/60
x = 20

check..
0.20(60) = 12
12 = 12 (correct)

so 20% of 60 is 12

A baseball player hits a pop fly ball toward left field where it is caught by a player at a height of 5 feet. The ball was hit a

MakcuM [25]

Answer:

The range of the function are the values of height which are from 3, 4, 5, ..., 50

Step-by-step explanation:

The given parameters are;

The height at which the ball is caught = 5 feet

The height at which the ball was hit = 3 feet

The maximum height reached by the ball = 50 feet

The height of the ball given as a function of time is f(t) s = u·t - 1/2·g·t²

Where;

s = 50 feet

g = 9.81 m/s²

Therefore, we have;

50 = u·t - 1/2 × 9.81 × t²

50 = u·t - 4.905 × t²

Therefore, the range are obtainable values for f(t) which range from 3 to 50.

Solve for a and b in the following circles:<br> A)

rjkz [21]

Given:

A quadrilateral inscribed in a circle.

To find:

The values of a and b.

Solution:

A quadrilateral inscribed in a circle. So, the quadrilateral is a cyclic quadrilateral.

We know that the sum of the opposite angles of a cyclic quadrilateral is 180 degrees.

$a+79^\circ=180^\circ$

$a=180^\circ-79^\circ$

$a=101^\circ$

We know that the measure of arc is twice of measure of subtended angle on that arc.

$(110^\circ+b)=2(96^\circ)$

$110^\circ+b=192^\circ$

$b=192^\circ-110^\circ$

$b=82^\circ$

Therefore, the value of a is 101 degrees and the value of b is 82 degrees.
