Answer:

a) f(4) = 2(4) - 5 = 3

Step-by-step explanation:

First, we look at the function, and we see different domain restrictions.

We are given the value of 4. The first equation has a domain restriction which includes 4 as it has the line below the greater than sign.

So, the first equation must work.

So our answer is A.

Answer:

Answer:

  {33, 75, 142, 93, 90, 10}°

Step-by-step explanation:

Two angles are supplementary when their sum is 180°. That means the supplement of an angle is the difference between that angle and 180°.

  180° -{147, 105, 38, 87, 90, 170}° = {33, 75, 142, 93, 90, 10}°

Step-by-step explanation:

first you have to divide then after you divide you should get the answer

The balloon’s vertical distance above the ground is 860.0 ft

Right angle triangle are triangle that has one of its sides as 90 degrees. The side of the triangle can be found using trigonometric ratios. Therefore,

The horizontal distance from the landmark tot he hot balloon is 1579 feet and it is the hypotenuse side of the triangle formed. Therefore, the vertical height is the opposite sides.

Using trigonometric ratio,

sin 33° = opposite / hypotenuse

sin 33° = x / 1579

cross multiply

x = 1579 × sin 33

x = 1579 × 0.54463903501

x = 859.985036289

x = 860.0 ft

Step-by-step explanation

Answer:

Equation 1 matches with number 9.

Equation 2 matches with number 7.

Equation 3 matches with number 1.

Equation 4 matches with number 3.

Equation 5 matches with number 5.

Step-by-step explanation:

Equation 1:  −9x > −9

−9x > −9

Divide both sides by −9.

-9x/-9 = -9/-9

Since −9 is negative, the inequality direction is changed.

x < 1

x < 1 matches with the graphed solution of number 9.

So, Equation 1 matches with number 9.

Equation 2: 2x + 6≥ −2

2x + 6≥ −2

Step 1: Subtract 6 from both sides

2x + 6 − 6 ≥ −2 − 6

2x ≥ −8

Step 2: Divide both sides by 2

2x/2 ≥ −8/2

Step 3: Simplify

x  ≥  -4

x  ≥  -4 matches with the graphed solution of number 7.

So, Equation 2 matches with number 7.

Equation 3: x − 9 < −5

x − 9 < −5

Step 1: Add 9 to both sides.

x − 9 + 9 < −5 + 9

Step 2: Simplify

x < 4

x < 4 matches with the graphed solution of number 1.

So, Equation 3 matches with number 1.

Equation 4: −6x < −12

−6x < −12

Divide both sides by -6

-6x/-6 < -12/-6

Since −6 is negative, the inequality direction is changed

x > 2

x > 2 matches with the graphed solution of number 3.

So, Equation 4 matches with number 3.

Equation 5: -7x + 20 > 55

-7x + 20 > 55

Step 1: Subtract 20 from both sides.

−7x + 20 − 20 > 55 − 20

Step 2: Simplify

−7x > 35

Step 3: Divide both sides by -7.

-7x/-7 > 35/-7

Step 4: Simplify

x < -5

Since −7 is negative, the inequality direction is changed

x < -5 matches with the graphed solution of number 5.

So, Equation 5 matches with number 5.

Step-by-step explanation:

The first four-term of the sequence is found by the given equation [tex]a_{n-1} = 4a_n[/tex] is given as 144, 36, 9, and 9/4.

A sequence is a list of elements that have been ordered in a sequential manner, such that members come either before or after.

The given equation will be

[tex]\rm a_n = \dfrac{a_{n-1}}{4} \\\\a_{n-1} = 4a_n[/tex]

And

[tex]a_4 = 2 \dfrac{1}{4} = \dfrac{9}{4}[/tex]

For n = 4, we have

[tex]\rm a_{4-1} = 4a_4\\\\a_3 \ \ \ = 4*\dfrac{9}{4} \\\\ a_3 \ \ \ = 9[/tex]

For n = 3, we have

[tex]\rm a_{3-1} = 4a_3\\\\a_2 \ \ \ = 4*9 \\\\ a_2 \ \ \ = 36[/tex]

For n = 2, we have

[tex]\rm a_{2-1} = 4a_2\\\\a_1 \ \ \ = 4*36 \\\\ a_1 \ \ \ = 144[/tex]

See below.  Veronica's thinking is incorrect.  I've included what she is thinking, but the correct thinking is more useful, as noted below.

Step-by-step explanation:

I don't know what Veronica is thinking, other than:

(398 x 18) = (400*18 - 18)

She should be thinking:

(398 x 18) = (400 x 18) - (2*18).  The "2" is for the two extra groups of 18 that she will have when multiplying 400 x 18, instead of 398 x 18.

We can conclude the following about the box plots:

Median is the middle value which is represented by a vertical line that divides the rectangular box in a box plot.

Median for Group A is smaller than the median of Group B.

Range of a data set is the difference between the maximum value and the minimum value. Range is a measure of variability. The bigger the range, the more the variability and vice versa.

Range of Group A is larger than range of Group B.

The amount Marcia saved in interest by consolidating the two balances will be $105

It is given that

For Card A = 1,879.58 ; APR 14%; monthly = 43.73

For Card B = 861.00 ; APR 10% ; monthly = 18.29

Now [tex]\rm 5\ Years \times\ 12\ months =60\ months[/tex]

For Card [tex]A=43.73\times60=2623.80[/tex]

For Card [tex]B=18.29\times60=1097.40[/tex]

Now the [tex]\rm Total=2623.80+1097.40=3721.20[/tex]

Since Lowest APR is 10%. monthly rate: 0.83%

So the Total Card balance  [tex]1879.58+861=2740.58[/tex]

[tex]A=\dfrac{P\times r(1+r)^n}{(1+r)^n} -1[/tex]

[tex]A=\dfrac{2740.58\times(0.0083(1.0083)^{60}}{1.0083^{60}}-1[/tex]

[tex]A=2740.58\times0.022[/tex]

So monthly payment.

[tex]A=60.29[/tex]  

[tex]60.29\times60=3617.40[/tex]

For Separate cards: 3,721.20

For Consolidated:     3,617.40

The equation of the ellipse is required \frac{(x)^2}{16} +\frac{(y+4)^2}{25}=1

The required equation is

[tex]\frac{x^2}{16} +\frac{(y+4)^2}{25}=1[/tex]

It can be seen that the major axis is parallel to the y axis.

The major axis points are

[tex](h,k+a)=(0,1)\\(h,k-a)=(0,-9)\\k+a=1\\k-a=-9[/tex]

Subtracting the equations

[tex]2a=10\\\implies a=5[/tex]

The foci are

[tex](h,k+c)=(0,-1)\\(h,k-c)=(0,-7)[/tex]

[tex]k+c=-1\\k-c=-7[/tex]

Subtracting the equations

2c=6

c=3

k+c=-1 implies that k=-1-c

k=-1-3

k=-4

[tex]\frac{(x-h)^2}{b^2} +\frac{(x-h)^2}{a^2}=1[/tex]

So we get,

[tex]\frac{(x-0)^2}{4^2} +\frac{(y+4)^2}{5^2}=1[/tex]

[tex]\frac{(x)^2}{16} +\frac{(y+4)^2}{25}=1[/tex]

Therefore the equation is, [tex]\frac{(x)^2}{16} +\frac{(y+4)^2}{25}=1[/tex].
