The answer is 60. The formula is v=bxhxh/b or in this case 6x4x15/6. After you multiply the numerator you will get 360 and then you divide by 6 to get your answer: 60.

Given the Arithmetic series A1+A2+A3+A4 A 1 + A 2 + A 3 + A 4 8 + 11 + 14 + 17 + . . . + 68 What is the value of sum?

wolverine [178]

Because 17 - 14 = 14 - 11 = 3, the ratio of the arithmetic series is 3;

Then, A4 = 8 - 3 = 5; A3 = 5 - 3 = 2; A2 = 2 - 3 = -1; A1 = -1 - 3 = -4.

But 68 = A1 + ( n- 1 ) x r;

68 = -4 + ( n - 1) x 3;

( n - 1 ) x 3 = 72;

n - 1 = 24;

n = 25;

Finally, Sn = ( A1 + An) x n / 2; then, S25 = ( - 4 + 68) x 25/2;

S25 = 64 x 25 / 2;

S25 = 32 x 25;

S25 = 800;

The value of sum is 800.

The range of the function is $\{-19,-4,16\}$

Explanation:

The function is $f(n)=5n-4$

The domain of the function is $\{-3,0,4\}$

We need to find the range of the function.

The range can be determined by substituting the values of domain in the function.

Thus, the range of the function when the domain is -3 is given by

$f(-3)=5(-3)-4$

$=-15-4$

$=-19$

Thus, the range is -19 when $n=-3$

The range of the function when the domain is 0 is given by

$f(0)=5(0)-4$

$=0-4$

$=-4$

Thus, the range is -4 when $n=0$

The range of the function when the domain is 4 is given by

$f(4)=5(4)-4$

$=20-4$

$=16$

Thus, the range is 16 when $n=4$

Thus, the range of the function is $\{-19,-4,16\}$ when their corresponding domain is $\{-3,0,4\}$

Arranging the range in order from least to greatest is given by

$\{-19,-4,16\}$

Hence, the range of the function is $\{-19,-4,16\}$

A sales team estimates that the number of new phones they will sell is a function of the price that they set. They estimate that

USPshnik [31]

Answer:

$204

Step-by-step explanation:

The question is at what price x will the company maximize revenue.

The revenue function is:

$R(x) = 4,080x-10x^2$

The price for which the derivate of the revenue function is zero is the price the maximizes revenue:

$R(x) = 4,080x-10x^2\\\frac{dR(x)}{dx}=0=4,080-20x\\x=\frac{4,080}{20}\\ x=\$204$

The company will maximize its revenue when the price is $204.

Drag the expressions to show the order of their quotients from least to greatest

Damm [24]

Answer:

by solving the divisions

Step-by-step explanation:

8/9 ÷ 7/11 = 8/9 × 11/7 = 88/63 = 1.40
19/12 ÷ 3/10 = 19/12 × 10/3 =190/36 = 5.28
19/12 ÷ 1/15 = 19/12 × 15 = 285/12 = 23.75

8/9 ÷ 3/10 = 8/9 × 10/3 = 80/27 = 2.96.

now from the solutions you can get the least to greatest

1.40 , 2.96, 5.28 and 23.75

After getting answer in decimal form change it to fraction like how they set the question
