pound of Swiss cheese? Do not include $ in your answer.

Answer:

[tex]\frac{1}{128}[/tex]

Step-by-step explanation:

The n th term of a geometric sequence is

[tex]a_{n}[/tex] = a [tex](r)^{n-1}[/tex]

where a is the first term and r the common ratio, hence

[tex]a_{10}[/tex] = 4 × [tex](\frac{1}{2}) ^{9}[/tex] = 4 × [tex]\frac{1}{512}[/tex] = [tex]\frac{1}{128}[/tex]

Final answer:

The tenth term of the geometric sequence with the first term 4 and the common ratio of 1/2 is calculated using the formula for the nth term. Substituting the given values into the formula and simplifying yields the tenth term as 1/128.

Explanation:

To find the tenth term of a geometric sequence, we use the formula for the nth term in a geometric sequence which is an = a1 x r(n-1), where a1 is the first term, r is the common ratio, and n is the term number.

In this case, the first term a1 is given as 4 and the common ratio r is 1/2. To find the tenth term, we substitute n with 10 in the formula:

a10 = 4 x (1/2)(10-1)

This simplifies to:

a10 = 4 x (1/2)9 = 4 x 1/512 = 4/512 = 1/128

Therefore, the tenth term of the geometric sequence is 1/128.

Answer:

The Slope Formula ( x1, y1 ) And ( x2, y2 )

Step-by-step explanation:

When moving left, subtract from the x-coordinate and when moving right, add in the x-coordinate. When moving down, subtract from the y-coordinate and when moving up, add in the y-coordinate.

1) Given point = (0, 0). 3 units right and 4 units down means (0+3, 0-4) = (3, -4).

2) Given point = (5, 2). 4 units left and 2 units down means (5-4, 2-2) = (1, 0).

3) Given point = (-6, -1). 8 units right and 5 units up means (-6+8, -1+5) = (2, 4).

4) In Quadrant II, the x-coordinate is negative and the y-coordinate is positive. So taking R = (-6,6). 2 units right and 6 units down means (-6+2, 6-6) = (-4, 0).

5) In Quadrant IV, the x-coordinate is positive and the y-coordinate is negative. So taking R = (6,-6). 7 units left and 4 units up means (6-7, -6+4) = (-1, -2).

Answer:

Option A. [tex]4x+3y\leq 12[/tex] and [tex]x\geq 0[/tex]

Step-by-step explanation:

we know that

The solution of the first inequality is the shaded area below the solid line [tex]4x+3y=12[/tex]

The solid line passes through the points (0,4) and (3,0) (the y and x intercepts)

therefore

The first inequality is

Answer:

Question 6: 6.8

Question 7: 8295

Step-by-step explanation:

Question 6:

Let's say that each hamburger costs x amount of dollars, and each soda costs y amount of dollars. For the first statement, we purchase 7 hamburgers (so 7 times x) and 3 sodas (3 times y) to add up to 27.95. As an equation, this means that 7x+3y=27.95. Similarly, for the second statement, 5x+4y=23.40.

Putting these two side by side, we get:

7x+3y=27.95

5x+4y=23.40

Using Gauss-Jordan elimination, we can multiply the first equation by -4/3 and then add that to the second equation, resulting in

[tex]-13x/3 = 27.95*(-4/3)+23.40\\[/tex]

Simplifying, we get

[tex]-13x = 27.95*(-4)+23.4*3\\\\-13x = -41.6\\\\x=3.2[/tex]

Question 7:

Take the number of students as x and the number of teachers as y. There are 35 times as many students as there are teachers, so 35y=x. We know that the students and teachers added up equal 8544-12=8532 (as 12 seats are empty in the auditorium that can seat 8544, 8532 must be occupied), so x+y= 8532. Since 35y=x, 35y+y+8532, 36y=8532, and y= 237. Since the number of students is equal to x, and x=35y, 35*y=35*237=8295 students.

Answer:

A

Step-by-step explanation:

we have g(x) = 5x+3  

we know that 5x=f(x)

so g(x)=f(x)+3  

thus g(x) is obtained by adding 3 units to f(x)  

that's means the graph of g is obtained by translating the parent function f by 3 units up

Answer:

Step-by-step explanation:

There are two functions f(x) = 5x and g(x) = 5x + 3

This parent function f(x) has been translated to form a new function g(x) = 5x + 3

These linear functions can be represented by two lines y = 5x and y' = 5x' + 3

So when we shift line y = 5x by 3 units up on the y-axis then a new graph of

y = 5x + 3 will be formed.

Answer:

Angle measurements of 35°, 35°, and 110°

Angle measurements of 40°, 60°, and 80°

Step-by-step explanation:

If you specify only the three angles, you can have an infinite number of similar triangles of different sizes.

A is wrong. There can be only one triangle in which all three side lengths are specified.

C is wrong. The angles do not add up to 180°.

The descriptions which can describe more than one triangle is:

a)

Side lengths 6 ft, 8 ft and 10 ft.

First we check whether it form a triangle or not:

6+8=14>10

8+10=18>6

and

6+10=16>8

Yes, these side lengths form a triangle.

With the help of this only one unique triangle is possible.

b)

angle measurements of 35°,35° and 110°

First we check the sum of the angles:

35°+35°+110°=180°

Hence, more than one triangle is possible.

c)

angle measurements of 30°,40° and 50°

First we check the sum of these angles:

30°+40°+50°=120°≠180°

Hence, these angles measure do not form a triangle.

d)

angle measurements of 40°,60° and 80°

First we check the sum of these angles:

40°+60°+80°=180°.

Hence, more than one triangle is possible.

e)

side length of 4 cm, 6 cm and 9 cm.

First we check whether it form a triangle or not:

4+6=10>9

6+9=15>4

and

4+9=13>6

Hence, a unique triangle will be formed.

Answer:

x = 50

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 2 given angles in the lower triangle and subtract from 180 to find the third angle

third angle = 180° - (65 + 65)° = 180° - 130° = 50°

x = third angle = 50 ( vertical angles )

A triangle has to have three angles and they have to add up to 180 degrees so,

65+65=130

180-130=50

X=50 degrees because it is equal to the third angle.

Step-by-step explanation:

Answer:

so b=-9 while c=12.

Step-by-step explanation:

If you have x-intercepts 1 and -4, then that means f(1)=0 and f(-4)=0.

You are given [tex]f(x)=-3x^2+bx+c[/tex]

So you have the system of equations to solve:

[tex]f(1)=-3(1)^2+b(1)+c=0[/tex]

[tex]f(-4)=-3(-4)^2+b(-4)+c=0[/tex]

Evaluating the exponents:

[tex]-3(1)+b+c=0[/tex]

[tex]-3(16)-4b+c=0[/tex]

Doing a little bit of multiplying:

[tex]-3+b+c=0[/tex]

[tex]-48-4b+c=0[/tex]

Let's add 3 on both sides of equation 1 and 48 on both sides of equation 2:

[tex]b+c=3[/tex]

[tex]-4b+c=48[/tex]

Subtracting the equations will eliminate c.

Let's do that:

[tex]5b+0c=-45[/tex]

[tex]5b=-45[/tex]

Divide both sides by 5:

[tex]b=\frac{-45}{5}[/tex]

Simplify:

[tex]b=-9[/tex]

If b=-9 and b+c=3 then -9+c=3 implies c=9+3=12.

so b=-9 while c=12.

To find b and c for the parabola y=-3x^2+bx+c with x-intercepts 1 and -4, we express the equation in its factored form, then expand it. From the expansion, we see that b=-9 and c=-12.

To find the values of b and c in the equation y = -3x^2+bx+c, where the x-intercepts are given as 1 and -4, we use the following steps:

Answer:

a) maximum height is 156.25 ft

b) 6 seconds

Step-by-step explanation:

a) The maximum height can be found by finding the y-coordinate of the vertex. The vertex is the highest point in a parabola opened downward.

I start with by finding the t-coordinate of the vertex.

The t-coordinate of the vertex is [tex]\frac{-b}{2a}[/tex] where the expression [tex]-16t^2+92t+24[/tex] will need to be compared to [tex]at^2+bt+c[/tex].

We see that [tex]a=-16,b=92,c=24[/tex].

So the t-coordinate of the vertex is [tex]\frac{-b}{2a}=\frac{-92}{2(-16)}=\frac{-92}{-32}=\frac{23}{8}[/tex].

We can find the h, the height, that corresponds to this t by using the equation [tex]h=-16t^2+92t+24[/tex] where [tex]t=\frac{23}{8}[/tex].

So inserting 23/8 for [tex]t[/tex].

[tex]-16(23/8)^2+92(23/8)+24[/tex]

Plugging into calculator gives you 625/4.

So the maximum height is 625/4 or 156.25.

b) Let's find how long it takes the ball to hit the ground. If the ball is on the ground, then the distance between the ball and the ground is 0.  So we are looking to solve h(t)=0 for t.

So this is equation we are solving for t:

[tex]-16t^2+92t+24=0[/tex]

These numbers are big but since all the terms have a common factor we can make them slightly smaller.

That is, we are going to divide both sides by -4 and see

[tex]4t^2-23t-6=0[/tex]

It looks like it could be possible to factor.

a=4

b=-23

c=-6

We need to find two numbers that multiply to be ac and add up to be b.

a*c=4(-6)=-24

b=-23

So -24=-24*1 and -23=-24+1.

We are going to replace -23t with -24t+1t giving up something that should be factorable by grouping.

[tex]4t^2-23t-6=0[/tex]

[tex]4t^2-24t+1t-6=0[/tex]

Group the first 2 together and group the last two together:

[tex](4t^2-24t)+(1t-6)=0[/tex]

Factor what you can from each pair:

[tex]4t(t-6)+1(t-6)=0[/tex]

Now each term has a common factor of (t-6) so factor that out giving you:

[tex](t-6)(4t+1)=0[/tex]

Set both factors equal to 0 giving you

t-6=0              or               4t+1=0

  t=6               or               4t  =-1

  t=6               or                 t=-1/4

So it hit the ground in 6 seconds.

Final answer:

The maximum height of the ball is calculated to be at 2.875 seconds, and by inserting this time back into the height function, we get the max height. To determine when the ball hits the ground, we solve the quadratic function for when h(t) equals zero, finding that it occurs at approximately 5.4 seconds post launch.

Explanation:

To calculate the maximum height of the ball, we need to find the vertex of the quadratic function, which gives us the time when the maximum height is reached. The function is in the form h(t) = -16t^2 + 92t + 24. The time at which the maximum height occurs can be found using the formula -b/(2a), where a and b are coefficients from the quadratic function. Here, a = -16 and b = 92, so the time is t = -92/(2*(-16)) = 92/32 = 2.875 seconds. Inserting this back into the height function gives us the maximum height:

h(2.875) = -16(2.875)^2 + 92(2.875) + 24

Now, to find when the ball hits the ground, we need to find the positive root of the height function where h(t) = 0. The quadratic formula h(t) = -16t^2 + 92t + 24 is used to find the time values when the ball is at the ground level. Solving this equation, we get two possible times, and we're interested in the positive one since time cannot be negative.

Thus, we get that the ball reaches the ground at approximately 5.4 seconds.
