Hello I Have A Upcoming Test And Want To Know How To Solve This

Answers

Answer 1

Expression given:

[tex]g>1[/tex]

To know how to graph the given expression, it is easier if we determine what it means in words. In this case, this expression means all the values above one (without including one).

We know that one is not included as it has the sing ">", if the value were included, then it would have the sing "≥" or "≤".

This is important because when you are graphing, a discontinuous line is drawn for values not included, and a continuous one for included values.

Now, we would have to evaluate if it is the independent variable (generally called x), or the dependent variable (generally called y).

Assuming that g is the dependent variable, then the graph would be like this:

However, if the variable was de independent variable, then it would look like this:

We have to note that both graphs go from 1 to bigger values.

S = 1/3 x pi x r^2 + pi x r^2 x h

Answers

The solved equation for h is h= S/ pi x r^2-1/3.

The problem we are dealing with here is related to the literal equation,  where a literal equation is an equation that comprises basically letters. Formulas are an illustration of strict equations. Each variable within the condition "truly" speaks to an important part of the full relationship expressed by the equation. To illuminate a literal equation implies modifying the equation so a different variable stands alone on one side of the equals sign. We got to be told which variable we need to solve.

For the given equation,S=  1/3 x pi x r^2 + pi x r^2 x h

for th the equation will be

=>S=  pi x r^2(1/3 +h)

Answers

The cost of the cotton candy that Jessica purchased is $3.

What is the cost of candy?

The first step is to determine total amount spent on snacks. The total amount spent is the sum of the amount paid by Tom and Jessica.

Total amount spent = $9 + $4 = $13

Two ice creams and one cotton candy is bought. This can be represented with:

$13 = total cost of ice cream + cost of the cotton candy

$13 = (2 x$5) + c

$13 = $10 + c

Bobby can work at most 20 hours next week, but she needs to earn at least $150. Herdog-walking job pays her $6 per hour and her iob as a car wash attendant pays her $10 perhour. If d is the number of hours she walks dogs this week and w is the number of hours sheworks at the car wash, write a system of inequalities that represents Bobby's situation.

Answers

Solution:

Let d represent the number of hours Bobby walks dogs,

and w be the number of hours she works at the car wash.

Given that she can work at most 20 hours next week, this implies that the total number of hours she works is expressed as

[tex]d+w\leq20[/tex]

If her dog-walking job pays her $6 per hour, this implies that for d number of hours, she will earn

[tex]\begin{gathered} \frac{\$6}{1\text{ hour}}\times d\text{ hours} \\ =\$\text{ 6d} \end{gathered}[/tex]

and her iob as a car wash attendant pays her $10 per hour, similarly for w number of hours, she will earn

[tex]\begin{gathered} \frac{\$10}{1\text{ hour}}\times w\text{ hours} \\ =\$10w \end{gathered}[/tex]

Given that she needs to earn at least $150, this implies that her total earnings will be expressed as

[tex]6d+10w\ge150[/tex]

Hence, the system of inequalities that represents Bobby's situation is:

[tex]\begin{gathered} d+w\leq20 \\ 6d+10w\ge150 \end{gathered}[/tex]

Describe the graph of the quadratic function f (x) = -3x^2+ 6x + 5 by stating whether it opens upward or downward and stating how it is stretched or compressed when compared to the parent quadratic functionA. The parabola opens downward. It is compressed shorter by a factor of 3.B. The parabola opens upward. It is stretched taller by a factor of 3.C. The parabola opens downward. It is stretched taller by a factor of 3.D. The parabola opens upward. It is compressed shorter by a factor of 3.

Answers

Answer:

  B. The parabola opens upward. It is stretched taller by a factor of 3.

Step-by-step explanation:

You want to know how the quadratic opens, and how it is stretched or compressed, given its equation is f(x) = -3x^2 +6x +5.

Leading coefficient

The "leading coefficient" is the coefficient of the highest-degree term. That term is -3x^2, and its coefficient is -3.

The minus sign tells you the parabola opens downward.

The magnitude of 3 tells you the parabola is stretched vertically (taller) by a factor of 3.

Having said that, the constant ratio is 1/2. Using this ratio we can find the next three terms.

[tex]\begin{gathered} 8\cdot\frac{1}{2}=4 \\ 4\cdot\frac{1}{2}=2 \\ 2\cdot\frac{1}{2}=1 \end{gathered}[/tex]Therefore, the next three terms are 4, 2, and 1.

Identify the parent function for the function g (x) = x+9 from its function rule. Then graph g and identify what transformation of the parent function it represents.

Answers

The parent function of g(x) = x + 9 is the function f(x) = x.

The function f(x) = x is a linear function, that is, it has degree 1 (the higher exponent of the variable x is 1).

In order to get g(x) from f(x), we can see that the function value was increased by 9 units:

[tex]g(x)=f(x)+9[/tex]

Adding 9 units to the function means we have a translation of 9 units up.

Therefore the correct option is the third one.

as one equation. Using the following property

[tex]\sin^2\theta+\cos^2\theta=1[/tex]

We can eliminate the parameter theta adding the square of the coordinates

[tex]\begin{gathered} \sin^2\theta+\cos^2\theta=1 \\ 6^2(\sin^2\theta+\cos^2\theta)=6^2 \\ 6^2\sin^2\theta+6^2\cos^2\theta=6^2 \\ (6\sin\theta)^2+(6\cos\theta)^2=6^2 \\ (6\sin\theta)^2+(2\cdot3\cos\theta)^2=6^2 \\ (y)^2+(2x)^2=6^2 \\ y^2+4x^2=36 \\ \frac{x^2}{9}+\frac{y^2}{36}=1 \end{gathered}[/tex]

And this is the standard equation of an ellipse

[tex]\frac{x^{2}}{9}+\frac{y^{2}}{36}=1[/tex]

The constrain

[tex]\frac{\pi}{2}<\theta<\frac{3\pi}{2}\implies x<0[/tex]

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Sandy uses clay= 3 1/2 pounds for 7 vase

So, for 1 vase amount of clay used

= 7/2 x 1/7

= 1/2 pounds

Now, for 21 small vases amount of clay used

=21 x 1/2

= 21/2

= 10 1/2 pounds.

guest. Write an inequality to calculate your total cost (T) based on the

If you have a total budget of $1000 how many guests can you

Answers

The inequality that can be used to calculate total cost (T) based on the number of guests (g) is 225 + 15g ≤ 1000.

If you have a total budget of $1000, 51.67 guests can be invited.

How to write inequality equation?

Cost of hall rent = $225Caterer's charge per guest = $15Total cost = TNumber of guests = g

Total cost = Cost of hall rent + Caterer's charge per guest(Number of guests)

225 + 15g ≤ T

If you have a total budget of $1000

225 + 15g ≤ T

225 + 15g ≤ 1000

substract 225 from both sides

15g ≤ 1000 - 225

15g ≤ 775

divide both sides by 15

g ≤ 775 / 15

g ≤ 51.66666666666666

Approximately,

g ≤ 51.67

So therefore, the inequality to represent the situation is 15g ≤ 1000 - 225 and about 51.67 guests can be invited if you have a budget of $1000
