The length of the base of a triangle is twice it’s height. If the area of the triangle is 441 square kilometers, find the height
Answers
Answer:
21 kilometers
Step-by-step explanation:
Let the height be [tex]x[/tex]. Then, the length of the base is [tex]2x[/tex]. The formula for the area is of the triangle is given by base*height/2. Therefore, the area of the triangle is equal to [tex]\frac{x \cdot 2x}{2} = x^2[/tex], which is in turn equal to 441. Since [tex]x[/tex] must be positive, then [tex]21^2=441[/tex], meaning that the height is [tex]21[/tex] kilometers.

Polynomial long division is virtually identical to numerical long division, except that the quotient term does not require any guessing. It is simply the ratio of the leading terms of the dividend and divisor. As with numerical long division, the product of the quotient term and the divisor is subtracted from the dividend to form the new dividend for the next step.
The process stops when the dividend is of lower degree than the divisor.
In part (a), you need to make sure the dividend expression has all of the powers of x present. This means terms 0x³ and 0x² must be added as placeholders in the given dividend. They will become important as the work progresses.

Answer:
15 - 8x
Step-by-step explanation:
Remark
This all depends on how you read the question. In other words, which comes first 5 - 3x or 5x - 10. It's not clear.
If you do the first one first, you get
5 - 3x - (5x - 10) Remove the brackets.
5 - 3x - 5x + 10 Collect like terms
15 - 8x So that makes the middle one correct.
Now do it the other way.
5x - 10 - (5 - 3x)
5x - 10 - 5 + 3x
8x - 15
That answer isn't available here. So ..

Your friend offers to place a bet with you. He will pay you $1 if your favorite sports team wins the game on Tuesday night. But you will pay him $3 if his team wins. Your team has an 80% chance of winning, whereas his only has a 20% chance. This bet is in your favor. True or False.
Answers
False because $1 =$1 not $3
True. The expected value of the bet is positive ($0.2),
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
Let's calculate the expected value of the bet for both outcomes:
If your team wins: You get paid $1, so the expected value is 0.8 × $1 = $0.8
If your friend's team wins: You pay $3, so the expected value is 0.2 × -$3 = -$0.6
The overall expected value of the bet is the sum of these two outcomes: $0.8 + (-$0.6) = $0.2
Since the expected value of the bet is positive ($0.2), this means that on average, you can expect to win money if you take this bet. Therefore, the bet is in your favor.

It is the variable which is being measured in an experiment. Here, the test is that the number of sales depends on the number of contact.

find the solution to this system of equations x+y=1
2x-y+z=1
x+2y+z=8/3
Answers
9514 1404 393
Answer:
(x, y, z) = (1/3, 2/3, 1)
Step-by-step explanation:
We can use the first equation to write an expression for x that can be substituted into the other equations.
x = 1 -y
2(1 -y) -y +z = 1 ⇒ -3y +z = -1
(1 -y) +2y +z = 8/3 ⇒ y +z = 5/3
Subtracting the first of these equations from the second gives ...
(y +z) -(-3y +z) = (5/3) -(-1)
4y = 8/3
y = 2/3
z = 5/3 -y = 1
x = 1 -y = 1/3
The solution is (x, y, z) = (1/3, 2/3, 1).

At one time, the town had 740 acres of wetlands.
The wetland area in the town decreases by 5% per year.

The wetland area in the town increases by 95% per year.
Answers
Answer:
When t=10, the town is predicted to have around 443 acres of wetlands.
At one time, the town had 740 acres of wetlands.
The wetland area in the town decreases by 5% per year.
Step-by-step explanation:
Given
[tex]f(t) = 740 * (0.95)^t[/tex]
Required
The true statements
[tex](a)\ f(10) = 443[/tex]
We have:
[tex]f(t) = 740 * (0.95)^t[/tex]
Substitute 10 for t
[tex]f(10) = 740 * (0.95)^{10[/tex]
[tex]f(10) = 443[/tex]
Hence, (a) is true
[tex](b)\ f(t) = 740[/tex]
We have:
[tex]f(t) = 740 * (0.95)^t[/tex]
Substitute 740 for f(t)
[tex]740 = 740 * (0.95)^t[/tex]
Divide through by 740
[tex]1 = 0.95^t[/tex]
Express 1 as 0.95^0
[tex]0.95^0 = 0.95^t[/tex]
Cancel out the bases
[tex]0 = t[/tex]
[tex]t = 0[/tex]
Hence, the area had 740 acres initially;
(b) is true
[tex](c)\ r = 5\%[/tex]
We have:
[tex]f(t) = 740 * (0.95)^t[/tex]
Using the general formula
[tex]f(t) = a * b^t[/tex]
By comparison:
[tex]b = 0.95[/tex]
0.95 < 1 means that:
[tex]b = 1 - r[/tex] --- where r = rates
[tex]0.95 = 1 - r[/tex]
Collect like terms
[tex]r = 1 - 0.95[/tex]
[tex]r = 0.05[/tex]
Express as percentage
[tex]r = 5\%[/tex]
Hence, (c) is true
[tex](d)\ f(10) = 492[/tex]
In (a)
[tex]f(10) = 443[/tex]
Hence, (d) is false
[tex](e)\ r = 95\%[/tex]
In (c)
[tex]r = 5\%[/tex] ---- decrement
Hence, (e) is incorrect
Answer: When the town is predicted to have around 443 acres of wetlands.
At one time, the town had 740 acres of wetlands.
The wetland area in the town decreases by 5% per year.

5^2^x = 5^3^(x+3)
We know a^b^c = a^(b*c)
5^(2x) = 5^(3(x+3))
5^(2x) = 5^(3x+9)
The bases are the same so the exponents are the same
2x = 3x+9

An investor puts $800 into an account that pays 7.5% interest compounded annually. The total amount A in the account after t years is given by which function below?
A = 800(1.75) ^t
A = 800(1.075) t
A = 800(1.075)^ t
A = 800 + (1.075)^ t
Answers
Answer:
A = 800( 1.075)^(t)
Step-by-step explanation:
The equation for interest is
A = p (1+r/n) ^ nt where p is the principle, r is the interest rate, n is the number of times per year and t is the years
A = 800( 1+ .075/1)^(1*t)
A = 800( 1.075)^(t)
Let's see
[tex]\\ \tt\leadsto A=P(1+r/n)^{nt}[/tex]
n is 1[tex]\\ \tt\leadsto A=P(1+r)^t[/tex]
[tex]\\ \tt\leadsto A=800(1+0.075)^t[/tex]
[tex]\\ \tt\leadsto A=800(1.075)^t[/tex]

A perfect square trinomial will factor into two expressions that are the same, for example: x^2 + 6x + 9 = (x + 3)(x + 3). Since this problem has a C value of 49, it will factor into (x + 7)(x + 7). 7 doubled is 14, therefore one possible value of B is 7.
21. (4) 2, -12
x^2 + 10x + 25 = 24 + 25

x = 2, -12
22. (3) 3 + sqrt(17)
x^2 - 6x = 8
Complete the Square
x^2 - 6x + 9 = 8 + 9

x - 3 = +/- sqrt(17)
x = 3 + sqrt(17), 3 - sqrt(17)
