Answer:
1078m²
Step-by-step explanation:
Formulas:
Total Surface Area = 2B + Ph
Area = 1/2bh
Solve:
19 × 17 = 323
19 + 19 + 17 + 17 = 72
h = 6m
B = 323m
P = 72m
Total Surface Area = 2(323m) + (72m × 6m) = 1078m²
Find the value of the trig function indicated
Answer:
A. (2√13)/13
Step-by-step explanation:
Recall, SOHCAHTOA.
Thus,
Cos θ = Adjacent/Hypotenuse
Adjacent = 16
Hypotenuse = 8√13
Therefore,
Cos θ = 16/(8√13)
Rationalize
Cos θ = (16*√13)/(8√13*√13)
Cos θ = (16√13)/(8*13) = (2√13)/13

Which number completes the inequality? 2/3
Answer: it’s 3/4
Step-by-step explanation: you have to make the Denominator equal for all of them In order to be able to compare. So if you make the denominator equal to 36 you then have to multiply the numerator by the same number you did for the denominator. Once doing that you will find that 24/36 < 27/36 < 28/36

Which choice is equivalent to the expression below?
✓-27
Square root of a negative value, so it will have a complex part.
We have that:
[tex]\sqt{-a^2} = ai[/tex]
In this question:
The square root of -27 can be factored as:
[tex]\sqrt{-27} = \sqrt{3(-9)} = \sqrt{3}\sqrt{-9} = 3i\sqrt{3}[/tex]
So the correct answer is given by option C.
What is the solution of the equation z +8 = 21?
Answer: 13
Explanation:
21-8=13
z = 13 is the solution of the equation z +8 = 21.
What is simplification?When a mathematical expression is converted into an equivalent, typically shorter statement, it becomes simpler. Procedure simplification is one method to encourage uniformity in work effort, expense, and duration. It reduces diversity and variation that is detrimental, pointless, or unnecessary.
Given, an expression z + 8 = 21
Simplifying it,
z = 21 - 8
z = 13
Therefore, The answer to the equation z + 8 = 21 is z = 13.

If f(x)=x squared-2x and g(x) = 6x+4 for which is a value of x does (f+g)(x) =0
Answer:
For [tex]x = -2[/tex]
Step-by-step explanation:
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
[tex]ax^{2} + bx + c, a\neq0[/tex].
This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:
[tex]x_{1} = \frac{-b + \sqrt{\Delta}}{2*a}[/tex]
[tex]x_{2} = \frac{-b - \sqrt{\Delta}}{2*a}[/tex]
[tex]\Delta = b^{2} - 4ac[/tex]
In this question:
[tex]f(x) = x^2 - 2x[/tex]
[tex]g(x) = 6x + 4[/tex]
[tex]f(x) + g(x) = (f+g)(x) = x^2 - 2x + 6x + 4 = x^2 + 4x + 4[/tex]
Which is a value of x does (f+g)(x) =0
[tex]x^2 + 4x + 4[/tex]
Quadratic equation with [tex]a = 1, b = 4, c = 4[/tex]
So
[tex]\Delta = 4^{2} - 4*1*4 = 0[/tex]
[tex]x_{1} = \frac{-4 + \sqrt{0}}{2} = -2[/tex]
[tex]x_{2} = \frac{-4 - \sqrt{0}}{2} = -2[/tex]
For [tex]x = -2[/tex]

How much money is needed to be invested now to obtain $12,100 8 years from now if this amount is invested at 7.25% compounded continuously?
Answer:
$6,911.92
Step-by-step explanation:
Given the following
Amount A = $12,100
Time t = 8yrs
Rate r = 7.25%
Required
Principal P
Using the compound interest formula;
A = P(1+r)^n
12,100 = P(1+0.0725)^8
12,100 = P(1.0725)^8
12100 = 1.7506P
P = 12,100/1.7506
P = 6,911.92
Hence the amount invested would have been $6,911.92
An air conditioning system can circulate 430 cubic feet of air per minute. How many cubic yards of air can it circulate per minute?
Divide the number of cubic feet that it can circulate by the number cubit feet per cubic yard. That gives the number of cubic yards that it can circulate. It can circulate about 10.37 cubic yards per minute.
The air conditioning system can be circulate in 15.92 cubic yards of air per minute.
Here,
An air conditioning system can circulate 430 cubic feet of air per minute.
We have to find the cubic yards of air which can be circulate in per minute.
What is the value of cubic yard in cubic feet?
1 cubic yard = [tex](3 ft)^3[/tex] = 27 cubic feet.
Now,
1 cubic yard = [tex](3 ft)^3[/tex] = 27 cubic feet.
Hence, Cubic yards of air circulate in per minute = 430/27 = 15.92
So, The air conditioning system can be circulate in 15.92 cubic yards of air per minute.

The "middle" term of the trinomial form of (3x + 5)(4x – 3)
is:
29x
- 3x
O 11x
0 2x
I want the answer the steps
Answer:
The "middle" term is 11x.
Step-by-step explanation:
(3x + 5)(4x - 3)
Solve this by using FOIL: first – outer – inner – last
F: 3x • 4x = 12x²
O: 3x • -3 = -9x
I: 5 • 4x = 20x
L: 5 • -3 = -15
Combine the terms.
12x² - 9x + 20x - 15
Combine like terms.
12x² + 11x - 15
The "middle" term is 11x.
