You have 19 digs for your current volleyball season. There are 5 games left in the season. You want to break your previous record of 26 digs in a season. Write and solve an inequality that represents the number x of digs you must get in the remaining 5 games to break your record

Solution: The function that represents the Grace earning each week is defined as [tex]e(h)=9h[/tex], where [tex]e(h)[/tex] is in dollar and [tex]h[/tex] is the time in hours. domain of the function [tex]e(h)=9h[/tex] is [10,20].

Explanation:

Let, Grace works for h hours per week.

For one hour she get $9.

For h hours she get [tex]\$(9\times h)=\$9h[/tex].

So, the function that represents the Grace earning each week is defined as [tex]e(h)=9h[/tex].

It is given that she works from 10 to 20 hours per week, therefore the value of h lies between 10 to 20. Hence the Grace's earnings for each week is defined as [tex]e(h)=9h[/tex] and the domain of the function [tex]e(h)=9h[/tex] is [10,20].

12/4=x/20

x=60

60 people are needed

4x3=12 right. Then 20x3=60.

Step 1. Factor out the common term 2

n - 2 = 2(5n + 2)/2

Step 2. Cancel 2

n - 2 = 5n + 2

Step 3. Subtract n from both sides

-2 = 5n + 2 - n

Step 4. Simplify 5n + 2 - n to 4n + 2

-2 = 4n + 2

Step 5. Subtract 2 from both sides

-2 - 2 = 4n

Step 6. Simplify -2 - 2 to -4

-4 = 4n

Step 7. Divide both sides by 4

-1 = n

Step 8. Switch sides

n = -1

To find the value of n, rearrange the equation and simplify to solve for n.

To find the value of n, we need to solve the given equation. First, distribute the 2 on the right side:

n - 2 = 10n + 4

Next, subtract 10n from both sides:

n - 10n - 2 = 4

Combine like terms:

-9n - 2 = 4

Then, add 2 to both sides:

-9n = 6

Finally, divide both sides by -9 to solve for n:

n = -6/9 which simplifies to n = -2/3.

Answer-

The abs. minimum value of the given function was found to be 3.

Solution-

Here, the given function is,

[tex]f(x)=x^4-x^2-2x+5[/tex]

Then, calculating its first derivative,

[tex]{f}'(x)=4x^3-2x-2[/tex]

Then, calculating its second derivative,

[tex]{f}''(x)=12x^2-2[/tex]

Then, calculating all the critical values of the given function by equating the first derivative to 0,

[tex]\Rightarrow {f}'(x)=0[/tex]

[tex]\Rightarrow 4x^3-2x-2=0[/tex]

[tex]\Rightarrow 2x^3-x-1=0[/tex]

[tex]\Rightarrow 2x^3-x-1=0[/tex]

[tex]\Rightarrow 2x^3-2x+x-1=0[/tex]

[tex]\Rightarrow 2x(x^2-1)+(x-1)=0[/tex]

[tex]\Rightarrow 2x(x+1)(x-1)+(x-1)=0[/tex]

[tex]\Rightarrow (x-1)(2x(x+1)+1)=0[/tex]

[tex]\Rightarrow (x-1)(2x^2+2x+1)=0[/tex]

[tex]\Rightarrow (x-1)=0[/tex]    ( ∵ ignoring the imaginary roots)

[tex]\Rightarrow x=1[/tex]

Putting the value of x, in the second derivative,

[tex]{f}''(1)=12(1)^2-2=10[/tex]

As, the value of f"(x) is positive, the function attains its minimum value at x=1.

So, f(1) will give the absolute minimum value of the function,

[tex]f(1)=(1)^4-(1)^2-2(1)+5=3[/tex]

∴ The abs. minimum value of the given function is 3.

The product of -2 1/2 and -3 1/3 is 8 1/3. This is calculated by converting mixed numbers into improper fractions and then multiplying. Multiplying two negative numbers gives a positive result.

To compute the product of -2 1/2 and -3 1/3, first convert these mixed numbers into improper fractions.  -2 1/2 can be converted to -5/2 and -3 1/3 is -10/3.  Then, simply multiply these two fractions:

(-5/2) x (-10/3) = 50/6 = 25/3 or 8 1/3 .So the product of -2 1/2 and -3 1/3 is positive 8 1/3. Remember, multiplying two negative numbers results in a positive product.

Answer:

Step-by-step explanation:

There are two parallel lines given.

Two transversals cut them.

Here m and n are parallel.

Two transversals cut them so that a triangle is formed.

Let us use the property that sum of angles of a triangle = 180

Bottom angle of triangle = 39 (vertically opposite angles)

Top left angle = 4x+3 (vertically opposite angles)

Top right angle = 180-6x (linear pair property)

Now add these 3 and equate to 180

39+4x+3+180-6x = 180

2x = 42

Or x = 21

The inverse function is [tex]\( f^{-1}(x) = \frac{x + 7}{4} \)[/tex].

To find the inverse function of [tex]\( f(x) = 4x - 7 \)[/tex], we follow these steps:

1. Replace [tex]\( f(x) \) with \( y \): \( y = 4x - 7 \)[/tex].

2. Swap[tex]\( x \) and \( y \): \( x = 4y - 7 \)[/tex].

3. Solve this equation for [tex]\( y \)[/tex].

So, let's solve for [tex]\( y \)[/tex]:

[tex]\[ x = 4y - 7 \][/tex]

Add 7 to both sides:

[tex]\[ x + 7 = 4y \][/tex]

Divide both sides by 4:

[tex]\[ \frac{x + 7}{4} = y \][/tex]

Thus, the inverse function of [tex]\( f(x) = 4x - 7 \)[/tex] is:

[tex]\[ f^{-1}(x) = \frac{x + 7}{4} \][/tex]

Answer:

The second gear will complete 75 complete revolutions

Step-by-step explanation:

- There are two connected gears

- One has 60 teeth and the other has 40 teeth

- The two gears have different revolutions depends on the number of

  their teethes

- They do the same job

- The relation between them is

   [tex]n_{1}*c_{1}=n_{2}*c_{2}[/tex], where n is the number of the complete

   revolutions and c is the number of the teeth

- The gear which has less teethes makes more complete revolutions

∵ [tex]n_{1}[/tex] = 50

∵ [tex]c_{1}[/tex] = 60

∵ [tex]c_{2}[/tex] = 40

- Substitute these values in the rule below

∵ [tex]n_{1}[/tex] × [tex]c_{1}[/tex] = [tex]n_{2}[/tex] × [tex]c_{2}[/tex]

∴ 50 × 60 = [tex]n_{2}[/tex] × 40

∴ 3000 = 40 [tex]n_{2}[/tex]

- Divide both sides by 40

∴ [tex]n_{2}[/tex] = 75 complete revolutions

The second gear will complete 75 complete revolutions

Answer:

The number of melon was 3 and the number of apples was 45.

Step-by-step explanation:

1. Melons cost $20 per crate and apples cost $8 per create. If the total was 48 crates for $420, you can make the following system of equations, where [tex]x[/tex] is the number of melons and [tex]y[/tex] is the number of apples:

[tex]\left \{ {{x+y=48} \atop {20x+8y=420}} \right.[/tex]

2. By applying the Method of substitution, you can solve for [tex]y[/tex] in the first equation and substitute it into the second one to find [tex]x[/tex]. Then, you can substitute the value of [tex]x[/tex] into the first equation to find [tex]y[/tex]:

[tex]y=48-x[/tex]

[tex]20x+8(48-x)=420\\20x+384-8x=420\\12x=36\\x=3[/tex]

[tex]3+y=48\\y=45[/tex]

Final answer:

The order consisted of 3 crates of melons and 45 crates of apples.

Explanation:

To solve the problem of determining the number of crates of melons and apples based on the total cost and quantity, we can use a system of linear equations.

Given that melons cost $20 per crate and apples cost $8 per crate, with a total order of 48 crates for $420, we can set up the following equations:

Solving this system of equations:

Thus, the order consisted of 3 crates of melons and 45 crates of apples.

Answer:

5000 square feet of lawn would provide the daily supplies of oxygen for 8 organisms.

Explanation:

 The daily supply of oxygen for a particular multi cellular organism is provided by 625 square feet of lawn

Total area of lawn provided = 5,000 square feet

Number of organism for which provided lawn area supplies oxygen = Total area of lawn provided/ Daily requirement of lawn area for 1 organism.

Number of organism for which provided lawn area supplies oxygen = 5000/625 = 8 organisms.

So 5000 square feet of lawn would provide the daily supplies of oxygen for 8 organisms.

A total of 5,000 square feet of lawn would provide the daily supplies of oxygen for 8 organisms based on the ratio given.

The question can be solved using the concept of ratios. The ratio of lawn to organisms is 625 square feet to 1 multicellular organism. So, if we have 5,000 square feet lawn area, we can find how many organisms it can support by setting up a proportion and solving for the unknown number of organisms.

Let's denote the unknown number of organisms as X. The proportion would then be: 625/1 = 5000/X.

To solve this equation for X, we can cross-multiply and divide. So, X = 5000 / 625 = 8 multicellular organisms.
