Answer:

c

Step-by-step explanation:

To find the maximum point, differentiate:

D' = -8p +160

Set to zero and solve for p:

D' = 0

⇒ -8p +160 = 0

⇒ 8p = 160

⇒ p = 20

Input p = 20 into the original equation to find D:

D = -4(20)² + 160(20) -310 = 1290

Therefore, the price is $20 and the maximum number of drills is 1,290

then multiplications and divisions (from left to right)

then additions and subtractions (from left to right)

remember, a fraction is a division ...

10 + (2 × 3)² ÷ 4 × 1/2³ =

= 10 + 6² ÷ 4 × 1/2³ =

= 10 + 36 ÷ 4 × 1/8 =

Answer:

Step-by-step explanation:

Distance formula:

d = rt

where d = distance, r = average speed and t = time travelled.

They told us that an object travels 30 meters in 20 seconds.

So we can say d = 30 and t = 20

If you put these values back into the distance formula you get:

d = rt

30 = r times 20

30 = 20 r

So now we want to find what "r" (average speed) is.

Divide both sides by 20.

20 r = 30

r =  [tex]\frac{30}{20}[/tex] = 1.5 meters per second.

✽ Simplify both sides of the equation.

[tex]\frac{x+2}{5}-\frac{x+1}{4}=1[/tex]

[tex]\frac{1}{5}x + \frac{2}{5} + \frac{-1}{4} = 1[/tex] (Distribute)

[tex](\frac{1}{5}x + \frac{-1}{4} ) + (\frac{2}{5} + \frac{-1}{4}) = 1[/tex] (Combine Like Terms)

[tex]\frac{-1}{20}x + \frac{3}{20} = 1[/tex]

✽ Subtract 3/20 from both sides.

[tex]\frac{-1}{20}x + \frac{3}{30} - \frac{3}{20} = 1 - \frac{3}{20}[/tex]

[tex]\frac{-1}{20}x = \frac{17}{20}[/tex]

✽ Multiply both sides by 20/(-1).

[tex]( \frac{20}{-1}) * (\frac{-1}{20}x) = (\frac{20}{-1}) * (\frac{17}{20})[/tex]

Hence, x = -17

Answer:

y= 16, 64, 256, 1024

y/x= 16/2, 64/3, 256/4, 1024/5,

Step-by-step explanation:

    This is just like any other equation, except instead of x being a number, it is an exponent. For example, when x equals 2, y equals 16 because y always equals four to the power of x.  This applies to all of the parts in your table. when x equals 3, y equals 4^3 (4 times 4 times 4) which is 64, and when x equals 4, y equals 4^4 (4 times 4 times 4 times 4), which is 256.

    For the y over x part that is just the value y, divided by the value x. For the first line on the table x equals 2, and we know y equals 16 (4^2 is 4 times 4, which is 16) so 16 divided by 2 is 8. That is the answer.

Hope this helps :)

Step-by-step explanation:

Its very simple, all you have to do is find the number to the power of two because its a square.

The equation represents the inequality will be y < −2x + 3.Option d is correct.

Linear inequalities involve at least one linear algebraic expression. A polynomial of degree 1 is compared to another algebraic expression of degree less than or equal to 1.

Different types of linear inequalities can be represented in a variety of ways.

The linear equation with slope m and intercept y is given as;

y=mx+c

The inequalities are as follows;

(a).  y > 2x +3

(b).  y < 2x+ 3

(c).  y > −2x+ 3

(d). y < −2x+ 3

Because the line meets the y-axis,(0,3)the y-intercept is 3.

The points are (0,3)and(1,1)

The line's slope may be calculated as follows.

[tex]\rm m= \frac{1-3}{1-0} \\\\ \rm m= -2[/tex]

On putting the given origin value;

[tex]y < -2x+3 \\\\0 < -2(0)+3\\\\0 < 3[/tex]

From all the data obtained we get the equation given in option d is correct.

Hence the equation that represents the inequality will be y < −2x + 3.Option d is correct.

Answer:

c

Step-by-step explanation:

Using limits, it is found that the correct statement is:

they give what y-values the function is AROUND the given x.

The limit of a function f(x) as a value of x = a is approached is given by:

[tex]y = \lim_{x \rightarrow a} f(x)[/tex]

The limit can be calculated at a point in which a function is not continuous, for example, in which we consider the lateral limits, which is not the exact value at x = a, but the value of the function as x approaches a by the left and by the right, hence the correct statement is:

they give what y-values the function is AROUND the given x.

Step-by-step explanation:

Work and answer shown above

The Domain is -4 ≤ x ≤ 2

Range = 2 ≤ y ≤ 6

We have given a graph of a function. We have to find the domain and the range of the function

The domain refers to the set of all valid input values for a function. It represents the values for which the function is defined or meaningful. In other words, it is the set of x-values that can be plugged into the function to obtain a corresponding y-value.

The range, on the other hand, refers to the set of all possible output values or y-values that result from evaluating the function with the input values from the domain. It represents the set of all values that the function can attain.

As we can see from the graph

value of x is greater than and equal -4 and less than and equals 2

Domain = -4 ≤ x ≤ 2

Value of y is grater than and equal to 2 and less than and equal to 6

Range = 2 ≤ y ≤ 6
