Consider the following advertisement.Which of the following calculations represents the cost of 2 dozen iris bulbs?
Answers
Answer:
C: (6 x $5)+(6 x $4)+(12 x $3)
Explanation:
The total number of bulbs bought = 2 dozens = 2 x 12 = 24
• The cost per bulb for the first half-dozen = $5
[tex]\text{Cost for the first half-dozen=6 x \$5}[/tex]• The cost per bulb for the next half-dozen = $4
[tex]\text{Cost for the next half-dozen=6 x \$}4[/tex]Out of 24 bulbs, we have calculated the cost for 12.
• The number of bulbs left = 24 - 12 = 12.
,• Each additional bulb is $3 per bulb.
The cost for the last 12 will be:
[tex]12\times\$3[/tex]Therefore, the cost for the 2 dozen iris bulbs will be:
[tex](6\times\$5)+(6\times\$4)+(12\times\$3)[/tex]The correct choice is C.

Find the amount and the present value of an annuity of P540 payable every end ofthe month at 7% compounded monthly for 4 years and 5 months.
Answers
We have to find the present value of a annuity of $540 payable every end of the month at 7% compounded monthly for 4 years and 5 months.
We can express the present value PV as:
[tex]PV=M\cdot\frac{[1-(1+r\/m)^{-n\cdot m}]}{r\/m}[/tex]where M: monthly payment (M = 540), r: annual nominal rate (r = 0.07), m: number of subperiods of compounding per year (m = 12) and n: number of years (n = 4+5/12).
We can replace the variables with its value and calculate PV as:
[tex]\begin{gathered} PV=540\cdot\frac{[1-(1+\frac{0.07}{12})^{-53}]}{\frac{0.07}{12}} \\ PV\approx540\cdot\frac{[1-(1.005833)^{-53}]}{0.005833} \\ PV\approx540\cdot\frac{1-0.7347}{0.005833} \\ PV\approx540\cdot\frac{0.2653}{0.005833} \\ PV\approx540\cdot45.4826 \\ PV\approx24560.60 \end{gathered}[/tex]Answer: The present value of teh annuity is P 24560.60.

To get the equation, we will use the equation of half-life:
[tex]\begin{gathered} N_t\text{ = N}_0(\frac{1}{2})^{\frac{t}{t_{\frac{1}{2}}}} \\ where\text{ N}_t\text{ = amount remaining} \\ N_0\text{ = initial amount} \\ t_{\frac{1}{2}\text{ }}\text{ = half-life} \end{gathered}[/tex][tex]N_t\text{ = 90\lparen}\frac{1}{2})^{\frac{t}{17.5}}[/tex]2) we need to find the remaining amount of Arsenic-74 after 70 days
t = 70
[tex]\begin{gathered} N_t=\text{ 90\lparen}\frac{1}{2})^{\frac{70}{17.5}} \\ N_t\text{ = 5.625 mg} \end{gathered}[/tex]So after 70 days, 5.625 mg will be left

What is the slope of a line parallel to the line whose equation is 3x-18y=-3783x−18y=−378. Fully simplify your answer.
Answers
ANSWER
Slope is 1/6
STEP-BY-STEP EXPLANATION
What to find? The slope of the line parallel to a given equation
Given equation
[tex]3x\text{ - 18y = -378}[/tex]The slope-intercept form of an equation is given below as
[tex]y\text{ = mx + b}[/tex]Where m is the slope of the line
y is the intercept of the y - axis
The next thing is to rewrite the above equation in the format of the slope-intercept equation
[tex]\begin{gathered} 3x\text{ - 18y = -378} \\ \text{ Isolate -18y by substracting 3x from both sides} \\ 3x\text{ - 3x - 18y = -378 - 3x} \\ -\text{ 18y = -3x - 378} \\ \text{Divide through by -18} \\ \frac{-18y}{-18\text{ }}\text{ = }\frac{-3x}{-18}\text{ - }\frac{378}{-18} \\ y\text{ = }\frac{1}{6}x\text{ + 21} \\ y\text{ = }\frac{1}{6}x\text{ + 21} \\ \text{ Since y = mx + b} \\ m\text{ = slope} \\ \text{Hence,m = }\frac{1}{6} \end{gathered}[/tex]For lines that are parallel to each other, the slope remains the same
[tex]m1\text{ = m2}[/tex]Therefore, the slope of the line parallel whose equation is y = 3x - 18y = -378 is 1/6
A data set contains an independent and a dependent variable. Which must be true of the data set if a linear function can be used to represent the data?
The set must have a constant additive rate of change.
The set must have a constant multiplicative rate of change.
The values in the set must be positive.
The values in the set must be increasing.
Answers
The correct answer is: The set must have a constant additive rate of change.
Let Y be a data set containing an independent and dependent variable.
The standard form of the equation of a line is given by y = mx + b, where x is an independent variable and y is a dependent variable, m is the slope, and b is the y-intercept.
Now, when m = 1,
y = x + c
When m = 2,
y = 2x + c = x + x + c
When m = 3,
y = 3x + c = x + x + x + c
As a result, the set must change at a constant additive rate.In order to avoid the function changing into an exponential function, which is not linear, the set must not have a constant multiplicative rate of change.As the set of real numbers is the domain of the linear function, the values in the set may be positive or negative.And, the values in the set must be rising.Learn more about data set here:

Answers
1/10⁻³ as a positive exponent is 10³.
How to convert a negative exponent to a positive exponent?
The negative exponent instructs us to rewrite the formula by getting the base's reciprocal and then switching the exponent's sign. A positive exponent indicates that the base should be multiplied by that many. Depending on the question at hand, you must flip an exponent from numerator to denominator or from denominator to numerator in order to change its sign.
Given, the exponent is y = 1/10⁻³
Multiplying both numerator and denominator of y with 10³, we get,
y = 10³/(10⁻³×10³) = 10³/1 = 10³
Therefore, 1/10⁻³ as a positive exponent is 10³.

The hypotenuse is 7m longer than the longer leg.
Length of the hypotenuse = (x+7) m

The sum of the measures of the internal angles of a triangle is of 180º, hence the following relation from triangle ABC is established.
<A + <B + <C = 180º.
The measures of angles A and B were already found, hence we can solve for the measure of angle C with the above equation as follows:
