Step-by-step explanation:

Got right on PLATO

The solution to the complex expression (3+7i) (-2-2i) -4i(5-9i) is -28 - 40i

A complex number is a number of the form a + bi, where a and b are real numbers, and i = √-1

i² = (√-1)² = -1

Given the expression:

(3+7i) (-2-2i) -4i(5-9i)

= -6 - 14i -6i + 14 - 4i(5 - 9i)

= 8 - 20i - 20i - 36

= -28 - 40i

The solution to the complex expression (3+7i) (-2-2i) -4i(5-9i) is -28 - 40i

7. Loan amount = $12000

Monthly payment = $380

Duration of the repayment = 3 years = 3(12) = 36 months.

Total amount Jason repaid = 36 × 380 = 13680

Interest on loan amount = amount repaid - loan amount

= 13680 - 12000

= 1680

Hence, total amount Jason paid in interest on loan = $1680 and the correct option is (D).

8. Loan amount = $35000

Monthly payment = $315

Duration of the repayment = 10 years = 10(12) = 120 months.

Total amount Gerald repaid = 120 × 315 = 37800

Interest on loan amount = amount repaid - loan amount

= 37800 - 35000

= 2800

Hence, total amount Gerald paid in interest on loan = $2800 and the correct option is (B).

Answer:

4.038 < 4.08 < 4.3 < 4.803

Step-by-step explanation:

We are given four decimal numbers and we have to arrange them in increasing order:

The numbers are 4.08, 4.3, 4.803, 4.038

The expanded form of these decimal numbers are:

[tex]4.08 = 4 + \displaystyle\frac{8}{100}[/tex]

[tex]4.3 = 4 + \displaystyle\frac{3}{10}[/tex]

[tex]4.803 = 4 + \displaystyle\frac{8}{10} + \displaystyle\frac{3}{1000}[/tex]

[tex]4.038 = 4 + \displaystyle\frac{3}{100} + \displaystyle\frac{8}{1000}[/tex]

Thus, the increasing order is:

4.038 < 4.08 < 4.3 < 4.803

The quadratic function is given by the equation [tex]h(t)=-0.075t^2+0.6t+2.5.[/tex]

The maximal height will be at vertex. Find t-coordinate of the parabola vertex:

[tex]t_{vertex}=-\dfrac{b}{2a}=-\dfrac{0.6}{2\cdot (-0.075)}=4\text{ seconds.}[/tex]

At t=4,

[tex]h(4)=-0.075\cdot 4^2+0.6\cdot 4+2.5=-1.2+2.4+2.5=3.7\text { feet. }[/tex]

Answer: it will take 4 seconds for the ball to reach the maximal height of 3.7 feet.

12 - 5[(4 +2)² - (22 + 10)]

Remember to follow PEMDAS. First, solve both parenthesis

12 - 5[(4 +2)² - (22 + 10)]

12 - 5[(6)² - (32)]

Next, solve the exponent

(6)² = 6 x 6 = 36

12 - 5[(36) - (32)]

Then, solve the bracket.

36 - 32 = 4

12 - 5[4]

Next, multiply

-5 x 4 = -20

Finally, subtract.

12 - 20 = -8

None of the above. The answer is -8. Please check the answers and the question again

Final answer:

Given that the average of m, n, and -1 is 0, the sum of m+n is calculated to be 1.

Explanation:

The question asks for the sum m+n given that the average of m, n, and -1 is 0. To find the sum, we can set up an equation using the definition of the average:

(m + n + (-1)) / 3 = 0

Solving this equation, we get:

m + n - 1 = 0

And once we add 1 to both sides:

m + n = 1

Therefore, the value of m+n is 1.

I'm pretty sure the unit price is $0.14. :)

Given dimensions of a rectangular garden are:

length = 2(x+6) feet

width = 3.5x feet

using the distributive property on length we get, length = 2x+12

Perimeter of a rectangle is 2(length+width)

So, P = 2(2x+12+3.5x)

Solving it we get,

P = 2(5.5x +12)   ..............adding like terms

P = [tex](2\times5.5)+(2\times12)[/tex] .............multiplying and adding

P = 11x+24

So, perimeter is 11x+24 feet. This value of fencing will be needed.

4x - 2x + 8 = 6(x + 4)   Given

(4x - 2x) + 8 = 6(x + 4)

2x + 8 = (6)(x) + (6)(4)

2x + 8 = 6x + 24    Distributive Property

2x - 6x + 8 = 6x - 6x + 24

-4x + 8 = 24      Subtraction Property of Equality

-4x + 8 - 8 = 24 - 8

-4x = 16    Subtraction Property of Equality

On the number line, smaller numbers are located to the left of larger numbers, which are located on the right.

So, if you have two numbers x and y on the number line, the smaller of the two will be on the left, the larger one on the right.

So, -13 is located to the right of -15, because it's larger.

For the same reason, -11 is located to the right of -13.

On the number line, you would have something like

<--------(-15)-------(-13)--------(-11)---------->

On a number line, negative values decreases as we move to the left while positive values increases to the right. Hence,

Starting from 0 to the left, we have - 1, - 2, - 3,... which continues in that sequence as decreases as we move to the left of the number line.

Moving towards the left, - 13 appears before - 15 ; Hence - 13 is located relative to the right of - 15 on the number line

Similary, - 11 appears before - 13 ; Hence - 11 is located relative to the right of - 13 on the number line.

Therefore, - 13 and - 11 are located to the right of - 15 and - 13 respectively on the number line.

Answer: The total weight  is [tex](1.14)(10^{7})[/tex] pounds.

Step-by-step explanation:

1. To solve this problem you need to multiply the number of whales by the weight. Based on the given information, the weight of each whale is approximately [tex](3.8)(10^{5})[/tex] pounds, therefore:

[tex](30)[(3.8)(10^{5})]=11,400,000[/tex] pounds.

3. To express the result in scientific notation, you must move the decimal point to the right until you have a non-zero number on the left of the decimal point. Then, it is:

[tex](1.14)(10^{7})[/tex]

Answer: The group weights 1.14x10^7 pounds

Step-by-step explanation:

The group has 30 whales.

Each whale weights 3.8x10^5 pounds, then, 30 whales weight 30 times that amount:

Total weight = (30)*(3.8x10^5)

Remember that for the scientific notation we want only one digit before the decimal point.

Here, i will use that 30 = 3x10^1

(3x10^1)*(3.8x10^5) pounds = (3*3.8)x10^(5 + 1) pounds

(11.4)x10^6 pounds

and 11.4 = 1.14x10^1

(11.4)x10^6 pounds =  1.14x10^(1 + 6) pounds = 1.14x10^7 pounds

Answer:

D

Step-by-step explanation:

The longest side is twice as long as the shortest side because lets suppose I have a triangle that has vertices with angles 30 and 60, the last one has to be 90 because the total is 180 degrees. Now for a 30 60 triangle, if the hypotenuse has a length of 2, the following ratios will hold true for the other two sides. The side that shares the 90 degrees and 60 degrees corners will be of length 1 and the side that shares the 30 degrees and 90 degrees corners (vertices) will be of length sqrt(3). This is true all the time. In this case the correct answer is that the longest side is twice as long as the shortest side because the longest side is the hypotenuse with length 2 and the shortest side will be the one that shares the 90 degrees and 60 degrees corners and is of length 1.

Final answer:

To estimate the division of 771 by 3.6, round 3.6 to 4 and divide 771 by 4 to get an approximate result of 192.75.

Explanation:

To estimate 771 divided by 3.6, we can round 3.6 to the nearest whole number, which is 4. The estimation calculation would then be 771 ÷ 4. Dividing 771 by 4 can be done by breaking down 771 into 760 + 11. Now, 760 ÷ 4 equals 190, and 11 ÷ 4 is approximately 2.75. Adding these two results, we get an estimated total of 192.75. Therefore, the estimated result of 771 ÷ 3.6 is approximately 192.75.

For each scenario, we multiply Rachel's daily earnings ($21) by the number of days worked to find her total earnings.

In 22a, Rachel earns 21 × 20 = $420, not $421 as stated.

In 22b, Rachel indeed earns 21 × 15 = $315, making the statement true.

Similarly, in 22c, Rachel earns 21 × 13 = $273, confirming the statement as true.

However, in 22d, Rachel's earnings for 13 days amount to 21 × 13 = $273, not $250, rendering the statement false.

Therefore, the true statements are 22b and 22c, while 22a and 22d are false.
