What is the surface area of this triangular prism rounded to the nearest tenth?

Final answer:

John can afford a maximum of 13 help sessions with his $170 budget for the year, after accounting for the $25.50 annual fee and the $10.50 per session charge.

Explanation:

To find the maximum number of help sessions John can use within his budget, we need to set up a simple algebraic equation. The total cost for the online help service consists of an annual fee plus the charge per help session. The equation to represent this situation will be:

Total Cost = Annual Fee + (Charge per Session × Number of Sessions)

We know the Annual Fee is $25.50, the Charge per Session is $10.50, and John's budget, or the Total Cost, is $170.

Let's denote the Number of Sessions as 'x'. The equation therefore becomes:

$170 = $25.50 + ($10.50 × x)

Subtracting the annual fee from both sides gives us:

$170 - $25.50 = $10.50 × x

$144.50 = $10.50 × x

Dividing both sides by $10.50 gives us the number of sessions John can afford:

x = $144.50 / $10.50

x = 13.7619...

Since John can't have a fraction of a session, we round down to the nearest whole number. John can afford a maximum of 13 help sessions within his budget of $170 for the year.

Shade in 9 boxes

12÷4= 3 (This is 1 fourth)

3×3=9 (This is 3 fourths)

From the said figure, 9 out of the 12 pieces of the figure are shaded

The figure is cut into 12 equal pieces, and 3/4 of the figure is shaded. To find out how many pieces are shaded, we need to calculate 3/4 of 12.

To do this, we can multiply 3/4 by 12:

3/4 * 12 = 36/4 = 9.

So, 9 out of the 12 pieces are shaded.

To visualize this, imagine a circle divided into 12 equal slices. If you shade 3/4 of the circle, you will shade 9 out of the 12 slices.

Therefore, 9 out of the 12 pieces of the figure are shaded

I would use the pythagorean theorem to find the lengths of each side. a² + b² = c².

Side AB is one we're looking for. If you make other right triangle with that same side you can see that one length is 4 and the other is 3. So, 4² + 3² = c² → 25 = c² → 5 = c. Side AB is length 5.

Side AC is another. Do the same with that side and you get that one length is 4 and the other is 3. (This is the same one as above) so side AC is length 5.

Side BC is the last one. One of the lengths is 1 and the other is 1 → 1² + 1² = c² → 2 = c² → 1.414213562 = c so side BC is approximately length 1.41.

Add each length up and you get a perimeter of roughly 11.4

the domain, is the values for "x", namely the values used up over the x-axis.

the arrowheads on the lines, indicate the graph continues, upwards and to the sides, so it keeps on going to infinity.

however, let's notice that the values between -3 and 5, are not used up, those are not part of the graph, and therefore, are not part of the domain, however -3 and 5 ARE part of it, whilst all numbers between them are not.

ANSWER

1. k=13

2. x=-10

EXPLANATION

The given function is

[tex]f(x) = {x}^{2} + 3x - 10[/tex]

To find f(x+5), plug in (x+5) wherever you see x.

This implies that:

[tex]f(x) = {(x + 5)}^{2} + 3(x + 5) - 10[/tex]

Expand:

[tex]f(x) = {x}^{2} + 10x + 25+ 3x + 15- 10[/tex]

Simplify to obtain

[tex]f(x) = {x}^{2} + 13x + 30[/tex]

We now compare with,

[tex]f(x) = {x}^{2} + kx + 30[/tex]

This implies that:

[tex]k = 13[/tex]

To find the smallest zero of f(x+5), we equate the function to zero and solve for x.

[tex]{x}^{2} + 13x + 30 = 0[/tex]

[tex] {x}^{2} + 10x + 3x + 30 = 0[/tex]

[tex]x(x + 10) + 3(x + 10) = 0[/tex]

[tex](x + 3)(x + 10) = 0[/tex]

[tex]x = - 10 \: or \: x = - 3[/tex]

The smallest zero is -10.

Answer:

Step-by-step explanation:

Given: [tex]4x-6=2x-2[/tex]

To solve for x, we need to isolate the x values on one side of the equation. Let's start by subtracting 2x from both sides.

[tex]2x-6=-2[/tex]

To further isolate x on one side of the variable, we should add 6 to both sides.

[tex]2x=4[/tex]

Answer: option c

Step-by-step explanation:

By definition, if you have:

[tex]\sqrt[n]{x}[/tex]

you can rewrite it has following:

[tex]x^{\frac{1}{n}}[/tex]

Therefore, keeping the above on mind, you can rewrite the expression given in the problem, as you can see below:

[tex]15x^{\frac{1}{3}}y^{\frac{1}{5}}=(15\sqrt[3]{x})(\sqrt[5]{y})[/tex]

Both terms are multiples of 15, then take the 15th root of both and multiply the exponents by 15. Therefore you obtain:

[tex]15\sqrt[15]{x^5y^3}[/tex]

The answer is:

c. [tex]15\sqrt[15]{x^{5}y^{3}}[/tex]

To express the expression using a radical we must remember that:

Transforming radical to exponential form:

[tex]\sqrt[n]{x}=x^{\frac{1}{n}}\\\sqrt{x}=x^{\frac{1}{2} }[/tex]

So, the given expression is:

[tex]15x^{\frac{1}{3}}y^{\frac{1}{5}}[/tex]

Its radical form will be:

[tex]15\sqrt[3]{x}\sqrt[5]{y}[/tex]

Then, the expression could be also equivalent to:

[tex]15\sqrt[3]{x}\sqrt[5]{y}=15\sqrt[15]{x^{5}}\sqrt[15]{y^{3}}\\\\15\sqrt[15]{x^{5}}\sqrt[15]{y^{3}}=15\sqrt[15]{x^{5}y^{3}}[/tex]

Have a nice day!

Answer:  option B.

Step-by-step explanation:

You can apply the elimination method:

- Multiply the first equation by -7 and the second equation by 3.

- Add both equations to cancel out the variable y.

- Solve for x

[tex]\left \{ {{(-7)9x+3y=(-39)(-7)} \atop {(3)(4x+7y)=(-57)(3)}} \right.\\\\\left \{ {{-63x-21y=273} \atop {12x+21y=-171}} \right.\\-------\\-51x=102\\x=-2[/tex]

- Substitute x=-2 into any of the original equations ans solve for y. Then:

[tex]9(-2)+3y=-39\\-18+3y=-39\\3y=-21\\y=-7[/tex]

The answer is:

B.

[tex]x=-2\\y=-7[/tex]

Solving the system of equations by elimination, we have:

[tex]\left \{ {{9x+3y=-39} \atop {4x+7y=-57}} \right.[/tex]

Then, multiplying the second equation by [tex]-\frac{9}{4}[/tex]

So,

[tex]\left \{ {{9x+3y=-39} \atop {4x*(-\frac{9}{4}) +7y*(-\frac{9}{4}) =-57*(-\frac{9}{4})}} \right\\\\\left \{ {{9x+3y=-39} \atop {-9x-\frac{63}{4}y=\frac{513}{4} }} \right\\\\-\frac{51}{4}y=\frac{357}{4}\\\\y=\frac{357}{4}*(-\frac{4}{51})=-\frac{1428}{204}=-7[/tex]

Then, substituting y=-7 into the first equation (also, we could substitute it into the first equation) we have:

[tex]9x+3(-7)=-39\\9x-21=-39\\9x=-39+21\\9x=-18\\x=\frac{-18}{9}=-2[/tex]

So, the solutions for the system of equations are:

[tex]x=-2\\y=-7[/tex]

Answer:

[tex]f(x)=x^3+x^2-4x-4[/tex]

Step-by-step explanation:

From the graph, the x-intercepts are;

[tex]x=-2[/tex]

[tex]x=-1[/tex]

[tex]x=2[/tex]

These are root of the polynomial function represented by the given graph.

By the remainder theorem;

[tex]f(-2)=0,f(-1)=0,f(2)=0[/tex]

According to the factor theorem, if [tex](x-a)[/tex] is a factor of [tex]f(x)[/tex], then [tex]f(a)=0[/tex]

This implies that;

[tex](x+2),(x+1),(x-2)[/tex] are factors of the required function.

Hence; [tex]f(x)=(x+1)(x-2)(x+2)[/tex]

We expand using difference of two squares to obtain;

[tex]f(x)=(x+1)(x^2-4)[/tex]

We expand using the distributive property to get;

[tex]f(x)=x^3-4x+x^2-4[/tex]

Rewrite in standard form to obtain;

[tex]f(x)=x^3+x^2-4x-4[/tex]

Answer:

Choice A: f(x) = x^3 + x^2 − 4x − 4

Step-by-step explanation:

Here's a great and simple answer.

Ok first we need to take the x intercepts to solve.

If we look at the graph we see the x ints are -2,+1 and +2.

To solve we need to put them into factor form

= (x-2) (x+2) and (x+1)

Simplify: (x-2) (x+2) = (x^2-4) and (x+1)

Now we take (x^2-4) and (x+1) and multiply them to find our answer

(x^2-4) (x+1)

= x^2(x) and x^2(1) = x^3 and x^2.

now the other: -4(x) and -4(+1) = -4x and -4

We have nothing common here so we just join them

= x^3 + x^2 - 4x - 4, and that is the same as choice A.

Let the soup can be represented by = s

Let the tuna can be represented by = t

Let the error of the scale in grams be represented by = e

4 cans of soup and 3 cans of tuna are placed on a correct scale and reads 80 ounces.

A can of soup and a can of tuna are placed on this scale, and it reads 24 ounces.

Two cans of tuna weigh 18 ounces on the bad scale.

Now equations becomes:

[tex]4s+3t=80[/tex]   ....(1)

[tex]s+t+e=24[/tex]    .... (2)

[tex]2t+e=18[/tex]     ..... (3)

From equation 3 we get

[tex]e=18-2t[/tex]

Putting this in equation 2

[tex]s+t+18-2t=24[/tex] = [tex]s-t=6[/tex]   ..... (4)  

Now we will solve equations 1 and 4.

Multiplying equation (4) by '4' we get, [tex]4s-4t=24[/tex]

Now subtracting this from equation 1, we get

[tex]7t=56[/tex]

[tex]t=8[/tex]

Now 4s+3t=80 ,

[tex]4s+24=80[/tex]

[tex]4s=56[/tex]

s = 14

And s+t+e = 24

14+8+e = 24

e = 2

Hence, a can of tuna weighs 8 ounces, a can of soup weighs 14 ounces and the amount of error is 2 ounces.

To find the amount of error in the scale and the correct weight of each type of can, set up a system of equations. Solve the equations to find that the amount of error in the scale is 0 ounces and the correct weight of each can is 15 ounces for soup and 9 ounces for tuna.

To find the amount of error in the scale and the correct weight of each type of can, we need to set up a system of equations.

Let's assume the weight of a can of soup is 's' and the weight of a can of tuna is 't'. From the given information, we can write the following equations:

1. s + t = 24   (equation 1)

2. 4s + 3t = 80  (equation 2)

We also know that two cans of tuna weigh 18 ounces on the bad scale. Therefore, we can write:

3. 2t = 18

From equation 3, we can solve for t: t = 18/2 = 9 ounces.

Substitute the value of t in equation 1 to find s: s + 9 = 24. Solving for s gives s = 15 ounces.

So, the amount of error in the scale is 24 - (15 + 9) = 24 - 24 = 0 ounces. The correct weight of each type of can is 15 ounces for soup and 9 ounces for tuna.

Answer:

Part A) The function written in vertex form is [tex]f(x)=15(x+2)^{2}-79[/tex]

Part B) The vertex of the function is the point [tex](-2,-79)[/tex]

Step-by-step explanation:

Part A) Write the function in vertex form

we know that

The equation of a vertical parabola in vertex form is equal to

[tex]y=a(x-h)^{2}+k[/tex]

where

(h,k) is the vertex of the parabola

In this problem we have

[tex]f(x)=15x^{2}+60x-19[/tex]

Convert to vertex form

Group terms that contain the same variable, and move the constant to the opposite side of the equation

[tex]f(x)+19=15x^{2}+60x[/tex]

Factor the leading coefficient

[tex]f(x)+19=15(x^{2}+4x)[/tex]

Complete the square. Remember to balance the equation by adding the same constants to each side

[tex]f(x)+19+60=15(x^{2}+4x+4)[/tex]

[tex]f(x)+79=15(x^{2}+4x+4)[/tex]

Rewrite as perfect squares

[tex]f(x)+79=15(x+2)^{2}[/tex]

[tex]f(x)=15(x+2)^{2}-79[/tex] -----> function in vertex form

Part B) Name the vertex for the function

we have

[tex]f(x)=15(x+2)^{2}-79[/tex]

The vertex of the function is the point [tex](-2,-79)[/tex]

The parabola open upward, so the vertex is a minimum

Final answer:

The two positive integers in question are 8 and 3, as they satisfy both conditions: one integer is 5 less than the other and their product equals 24.

Explanation:

The problem asks us to find two positive integers where one is 5 less than the other and their product equals 24. Let's denote the larger integer as 'x'. Then, the other integer would be 'x - 5'. We can set up the equation:

x(x - 5) = 24

Which simplifies to:

x² - 5x - 24 = 0

By factoring this quadratic equation, we end up with:

(x - 8)(x + 3) = 0

We are given the numbers are positive integers, so we take the positive root which is:

x = 8

Subsequently, the smaller integer would be:

8 - 5 = 3

So the two integers are 8 and 3.
