Answer:

The correct amount is $18

Step-by-step explanation:

The change in her checking account here refers to a reduction in balance due to a deduction made for a gym membership of $18  per year.

Integer, as we know, is a whole number,  not a fraction.

In all fairness, the integer will indicate the change in her checking account due to her gym  membership payment is $18, the first option out of the multiple choices provided

Answer:

a). 8100 bacteria

b). 519 bacteria

c). Infinite

Step-by-step explanation:

Population growth of a bacteria is given by the exponential function,

f(x) = [tex]P_{0}(1+\frac{r}{100})^{t}[/tex]

Where f(x) = Population after time 't'

[tex]P_{0}[/tex] = Initial population

r = Growth rate

t = Duration after t hours

If "100 bacteria gets tripled every hour"

300 = [tex]100(1+\frac{r}{100})^{1}[/tex]

3 = 1 + [tex]\frac{r}{100}[/tex]

r = 100×(3 - 1)

r = 200

So the function is, f(x) = [tex]100(3)^{t}[/tex]

a). Population after 4 hours,

    f(4) = [tex]100(3)^{4}[/tex]

          = 8100 bacteria

b). Population after 90 minutes Or 1.5 hours

     f(1.5) = [tex]100(3)^{1.5}[/tex]

             = 519.61

             ≈ 519 bacteria

c). Population after 72 hours,

    f(72) = [tex]100(3)^{72}[/tex]

            = Infinite

Answer and Step-by-step explanation:

To get this answer you need to understand what a function is, a function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output. If this is false, this is NOT a function. So, knowing that, the correct answers are, All functions have a dependent variable, All functions have an independent variable, and A horizontal line is an example of a functional relationship. So this 1st, 2nd, and 5th options.

Answer:

Step-by-step explanation:

We have tanπ3=−tan2π3=tan4π3=3–√

Since tan(3x)=3tanx−tan3x1−3tan2x

Thus tanπ/9,−tan2π/9,tan4π/9are solutions to the polynomial 3–√=3x−x31−3x2

On simplication, x3−33–√x2−3x+3–√=0.(1)

Since (tanπ9−tan2π9+tan4π9)2

=tan2π9+tan22π9+tan24π9

+ 2( -tanπ9tan2π9+tanπ8tan4π9−tan2π9tan4π9)

By sum and product pairs of roots in (1) above

(−33–√)2=tan2π9+tan22π9+tan24π9+2×−3

∴tan2π9+tan22π9+tan24π9=33

Answer:

Step-by-step explanation:

area of triangle = 1/2 * base * height = 1/2 * 9 = 9/2

area  of semicircle = 22/7 * {3 root 2 / 2}^2 = 22/7 *18 / 4 = 22/7 *9/2 = 198/14=99/7

area of figure =  99/7 + 9 /2 =18.6mm2

mark me as the brainliest

Answer:

area of figure= area of semi circle + area of triangle

area of semi circle= 1/2πr²

1/2×3.14×2.12×2.12

1/2×14.11

= 7.06

area of triangle = 1/2×base×height

but I am going to use the Pythagoras theorem to find the its height

= hypotenus² = base²+height²

3²=2.12²+h²

9=4.5+h²

9-4.5=h²

√4.5=√h²

h= 2.12

so area of triangle= 1/2×4.24×2.12

=4.5

area of figure = 70.6+4.5

= 75.1mm²

hope it helps even if its not correct just wanted to try

According to some reaserch,

To round to a significant figure:

1. look at the first non-zero digit if rounding to one significant figure

2. look at the digit after the first non-zero digit if rounding to two significant figures

3.draw a vertical line after the place value digit that is required

4. look at the next digit

5.if it's 5 or more, increase the previous digit by one

6.if it's 4 or less, keep the previous digit the same

fill any spaces to the right of the line with zeros, stopping at the decimal point if there is one

Answer:

14

Step-by-step explanation:

Make the two function equal to eachother and then, bring -8 to the right which will be added with 20 to get 28. Now you left with 2x on the left side, divide both sides by 2 to solve for (x). Thus x= 14.

Answer:

Option (1). (6, 0)

Step-by-step explanation:

The given question is incomplete; here is the complete question.

Which is the ordered pair for the point on the x-axis that is on the line parallel to the given line and through the given point (–6, 10)?

(6, 0)

(0, 6)

(−5, 0)

(0, −5)

Line in orange color is passing through two points (-8, 6) and (4, -4)

Slope of this line = [tex]\frac{\triangle y}{\triangle x}[/tex]

                            = [tex]\frac{6+4}{-8-4}[/tex]

                            = [tex]-\frac{10}{12}[/tex]

                            = [tex]-\frac{5}{6}[/tex]

Other line parallel to this line will have the same slope 'm' = [tex]-\frac{5}{6}[/tex]

Parallel line passes through a point (-6, 10).

Let the other point through which the parallel line passes is (a, b)

Now, [tex]-\frac{5}{6}[/tex] = [tex]\frac{10-b}{-6-a}[/tex]

-5(-a - 6) = 6(10 - b)

5a + 30 = 60 - 6b

5a = -6b + 60 - 30

5a = -6b + 30

a = [tex]-\frac{6}{5}b+6[/tex]

By satisfying with all the options we find only (6, 0) satisfy this equation.

6 = [tex]-\frac{6}{5}(0)+6[/tex]

6 = 6

Therefore, (6, 0) is the other point lying on the parallel line.

Option (1) will be the answer.

Step-by-step explanation:

First find f(3), which is the value of the blue line when x =3

g(-1) = 6

-6 f(3) - 6*g(-1)

Answer:

A I did the same quiz it’s A

Step-by-step explanation:

The correct option is "option A".

A function is graphed in the given figure.

We have to tell that which option is correct related to the graph.

What is a function ?

The function is the description of how the inputs relate to the output.  Each input has only one output.

According to the figure / graph ;

When x < 3

Then , y = [tex]x^{2}[/tex] + 6

Also , at , x = 3

We get an open interval.

So, we can say that ;

y = [tex]x^{2}[/tex] + 6 is valid for x < 3 not at x =3

Also , y = -x + 6 is valid for x ≥ 3 , here we get a close interval.

Thus , the correct option will be "option A" i.e.,

y = { x² + 6 , x < 3

and

y = { -x + 6 , x ≥ 3

Answer: 50 ft

Step-by-step explanation:

The correct function is h(t)=-16t^2+200t+50.

Hi, to answer this question we simply have to replace t =0 in the function given:

h(t)=-16t^2+200t+50.

h (0) = -16t^2+200t+50.

h(0) = 50

When the time is 0, the rocket is at the top of the building.

The rocket was launched from a 50 ft height.

Answer:

In standard form: x - 2y = -10

In slope intercept form: y = (1/2)x + 5

Step-by-step explanation:

y = total cost

y = flat cost + mileage cost

The flat cost is $5, so you get

y = 5 + mileage cost

The mileage cost depends on the number of miles, x.

1 mile costs $0.50

2 miles cost $0.50 * 2

3 miles cost $0.50 * 3

x miles cost $0.50 * x, or simply 0.5x

Now we add the mileage cost to our expression.

y = 5 + 0.5x

y = 0.5x + 5

In standard form:

0.5x - y = -5

x - 2y = -10

In slope intercept form:

y = (1/2)x + 5
