Step-by-step explanation:

Answer:

She ate 8 donuts the first day, 14 on the second, 20 on the third, 26 on the fourth, and 32 on the fifth day

Step-by-step explanation:

Over the course of 5 days, she ate 100 donuts, each day eating 6 more than the day before.  Let n be the number of donuts she ate on the first day, then she ate...

Day 1: n donuts

Day 2: n + 6 donuts    

Day 3: n + 12 donuts

Day 4: n + 18 donuts

Day 5: n + 24 donuts

Add the days together and get the equation...

n + (n + 6) + (n + 12) + (n + 18) + (n + 24) = 100

Now combine like terms and solve for n...

5n + 60 = 100

    5n = 40

    n = 8

She ate 8 donuts the first day, 14 on the second, 20 on the third, 26 on the fourth, and 32 on the fifth day

Answer:

(0,12)

Step-by-step explanation:

Just plug in 0 for x so (0-6)(0-2) = 12 so that's the y value.

Also, a y intercept has to be of the form (0,y) where y is some number.  The x value has to be 0, so that eliminates the last two options automatically, but if we put the x and y value we got together we get (0,12)

Answer:

(0,12)

Step-by-step explanation:

[tex]f(x) = (x - 6)(x - 2)[/tex]

To find out y intercept , plug in 0 for x and find out f(0)

y intercept are the value where the graph crosses y axis

[tex]f(x) = (x - 6)(x - 2)[/tex]

[tex]f(0)= (0-6)(0 - 2)=12[/tex]

When x is 0 the value of y is 12

Write y intercept as (0,y) that is (0,12)

Answer:

The solution in the attached figure

Step-by-step explanation:

we have

[tex]y<16x^{2}[/tex]

we know that

The solution of the inequality is the shaded area below the dashed line of the parabola

The equation of the dashed line is the vertical parabola [tex]y=16x^{2}[/tex]

therefore

The solution in the attached figure

The graph that represents the inequality is in the image at the end.

Which graph represents the inequality?

Here we have the inequality:

y < 16x²

This is a parabola that opens upwards, with a vertex at the point (0, 0).

The area shaded must be the area below the parabola, and because we have the symbol "<" we must graph the parabola with a dashed line instead of a solid line.

With this in mind, we can see that the correct option is the third graph.

Answer:

The measure of each angle is [tex]20\°[/tex]

Step-by-step explanation:

Let

x------> the angle on each side

we know that

[tex]x\°+140\°+x\°=180\°[/tex]

solve for x

[tex]2x\°=180\°-140\°[/tex]

[tex]2x\°=40\°[/tex]

[tex]x=20\°[/tex]

The range of the sample means calculated from the provided data is 2.2.

To find the range of the sample means, we first need to calculate the mean for each row and then find the range of these means.

Calculating the mean for each row:

1st row: (3 + 1 + 0 + 4 + 1) / 5 = 9 / 5 = 1.8

2nd row: (4 + 2 + 3 + 0 + 5) / 5 = 14 / 5 = 2.8

3rd row: (0 + 1 + 1 + 2 + 0) / 5 = 4 / 5 = 0.8

4th row: (4 + 1 + 4 + 4 + 2) / 5 = 15 / 5 = 3

5th row: (3 + 2 + 0 + 1 + 4) / 5 = 10 / 5 = 2

Now, let's find the range of these means:

Range = Maximum mean - Minimum mean

Range = 3 - 0.8 = 2.2

Therefore, the range of the values for the sample means is 2.2.

Answer:

180°

Step-by-step explanation:

The measures of the angles in the triangle shown are ...

81.87°, 60.26°, 37.87°

The sum of those measures is ...

81.87° + 60.26° + 37.87° = 180.00°

Answer: Option a.

Step-by-step explanation:

- Divide both sides of the expression by 7.8:

[tex]7.8e^{\frac{x}{3}ln5}=14\\\\\frac{7.8e^{\frac{x}{3}ln5}}{7.8}=\frac{14}{7.8}\\\\e^{\frac{x}{3}ln5}=\frac{14}{7.8}[/tex]

- By definition:

[tex]e^y=x[/tex]→[tex]y=ln(x)[/tex]

Then:

[tex]\frac{x}{3}ln5=ln(\frac{14}{7.8})[/tex]

- Now, you must solve for x.

Then, you obtain:

[tex]xln5=3ln(\frac{14}{7.8})[/tex]

[tex]x=\frac{3ln(\frac{14}{7.8})}{ln5}[/tex]≈[tex]1.0903[/tex]

The measure of angles in a rhombus can be found understanding the properties of a rhombus (i.e., opposite angles are equal and adjacent angles are supplementary) and possibly applying trigonometry in which angles are not aligned in regular horizontal or vertical manner. Specific measurements can be obtained using a protractor.

To find the measure of the numbered angles in the rhombus, you need to understand the geometric properties of a rhombus. The opposite angles of a rhombus are equal, and the adjacent angles are supplementary, meaning they add up to 180 degrees. Further, the diagonals of a rhombus bisect its angles, and they are perpendicular to each other, forming 90-degree angles where they intersect.

Clearly, the exact measures of the angles will depend on the specific information provided about the rhombus in your diagram. Here are some steps on how you might determine these measures:

Answer:

B) 200 + 4c - 6b

Step-by-step explanation:

Be,

c = number of cards sold at $4

b = number of cards purchased at $6

x = money at the beginning of the day = $200

y = money at the end of the day

The variables x and c owe positive values because they represent possession or income of money, while b must be negative because purchases are expenses.

Then, the following equation is formed:

y = x + 4c - 6b

Substituting x for its value, you get

y = 200 + 4c - 6b

Answer:

w = [tex]-\frac{9}{8}[/tex]

Step-by-step explanation:

The question is  [tex]4w-4+2(5w+8)=-2(w+3)[/tex]

We can first use distributive property to simplify, the distributive property is  [tex]a(b+c)=ab+ac[/tex]

Thus we have:

[tex]4w-4+2(5w+8)=-2(w+3)\\4w-4+10w+16=-2w-6[/tex]

Now we combine like terms and simplify to get the final answer for w.

[tex]4w-4+10w+16=-2w-6\\14w+12=-2w-6\\14w+2w=-6-12\\16w=-18\\w=\frac{-18}{16}\\w=-\frac{9}{8}[/tex]

Thus, w = [tex]-\frac{9}{8}[/tex]

Answer:

1.125

Step-by-step explanation:

we first open the brackets by multiplying every term inside the brackets by 2

We get the following equation: 4w-4+10w+16=-2w-6

collecting like terms together we get 4w+10w+2w=-6-16+4

   16w=-18

dividing both sides by 16 we get w=18/16

=9/8

= 1 1/8 or  1.125

Answer:

Step-by-step explanation:

Divide 2/3 by 4/5

Which is done by K(eep)C(hange)F(lip)

2/3 * 5/4 = 10/12 = 5/6

N= 5/6

Here is how we do it:

First, we must simplify 4/5n to 4n/5.

Then we simplify:   [tex]2/3n[/tex] to get [tex]2n/3.[/tex]

After we multiply both sides by the number 15.

[tex]12n =  10n[/tex]

Alright, now let's move them all together.

It would be: [tex]12n - 10n = 0[/tex]

Our last step is to simplify 12n - 10n to 2n.

Then we receive: [tex]2n = 0[/tex]

After we divide both sides by 2.

Our final answer is: [tex]n = 0[/tex]

Answer:

[tex]s = 21\ ft\\\\a = -6\ \frac{ft}{s^2}[/tex]

Step-by-step explanation:

To find the changes in the slope of the function s(t) we find its derivative

[tex]\frac{ds(t)}{dt} = 3t^2 - 18t +24\\[/tex]

Now we make [tex]\frac{ds(t)}{dt} = 0[/tex]

[tex]3t^2 - 18t +24 = 0[/tex]

[tex]3t^2 - 18t +24\\\\3(t^2-6t + 8)\\\\3(t-4)(t-2)\\\\t_1 =4\\t_2=2\\[/tex]

The particle changes direction for the first time at t = 2 sec

The position at t = 2 sec is:

[tex]s(t=2) = (2)^3 - 9(2)^2 + 24(2) + 1\\\\\s(2) = 21\ ft[/tex]

The acceleration after t = 2 sec is the second derivative of s(t), evaluated at t = 2:

[tex]\frac{d^2s(t)}{d^2t} = 6t -18\\\\\frac{d^2s(t)}{d^2t}(2) = 6(2) -18\\\\ a = 12-18\\\\a = -6\ \frac{ft}{s^2}[/tex]

Answer:

The position is 21 feet

The acceleration is -6 ft/sec²

Step-by-step explanation:

∵ s(t) = t³ - 9t² + 24t + 1

- where s is the displacement in feet and t is the time in second

∵ v(t) = ds/dt ⇒ velocity is the differentiation of s(t)

∵ a(t) = d²s/dt² = dv/dt ⇒ acceleration is the differentiation of v(t)

∴ v(t) = 3t² - 18t + 24

∵ When the particle reverses means v(t) = 0

∴ 3t² - 18t + 24 = 0 ⇒ ÷ 3

∴ t² - 6t + 8 = 0

∴ (t - 2)(t - 4) = 0

∴ t - 2 = 0 ⇒ t = 2 seconds

∴ t - 4 = 0 ⇒ t = 4 seconds

- That means the particle will change its direction first after 2 seconds

  and again after 4 seconds

∵ a(t) = dv/dt

∴ a(t) = 6t - 18

∵ t = 2

∴ a(2) = 6(2) - 18 = 12 - 18 = -6 ft/sec²

∵ s(t) = t³ - 9t² + 24t + 1

∴ s(2) = 2³ - 9(2)² + 24(2) + 1 = 21 feet

Where B is the area of the base and  H is the height.

Assuming that the base of the pyramid is a square, you have that B is:

[tex]B=(10units)^2=100units^2[/tex]

Substitute values into the formula, Then you obtain:

 [tex]V=\frac{(100units^2)(12units)}{3}=400units^3[/tex]

Answer:

Final answer is 400 cubic units.

Step-by-step explanation:

We have been given length of the base edge of square pyramid = a = 10 units

vertical height of the square pyramid = h = 12 units

Now we need to find the volume of the square pyramid.

So apply formula :

[tex]Volume = \frac{1}{3}a^2h[/tex]

[tex]Volume = \frac{1}{3}(10)^2(12)[/tex]

[tex]Volume = \frac{1}{3}(100)(12)[/tex]

[tex]Volume = \frac{1}{3}(1200)[/tex]

[tex]Volume = 400[/tex]

Hence final answer is 400 cubic units.
