Identify the 35th term of an arithmetic sequence where a1 = -7 and a18 = 95. (2 points)
Question 1 options:

1) 203

2) 197

3) 168

4) 163,

Answers

Arithmetic sequences have the same value added repeatedly. There are 17 increments between a1 and a18 and the value changes a total of 102 (95 - -7). 102 divided by 17 shows that the value of 6 is being added each time. The 35th term is then given by a1+(35-1)*6 = -7 + 34*6 = -7 + 204 = 197.

What is the value of x? The figure shows 2 right triangles, triangle K L J with right angle J and triangle L J M with right angle M. The measure of angle L K J is 30 degrees. The measure of angle L J M is 45 degrees. The length of side K L is 8 square root 2. The length of side L M is x. Enter your answer in the box.

Answers

Answer: The length of side X is 4.

In triangle KLJ, the hypotenuse is 8 square roots of 2. The side opposite the 30 degree angle is half of that amount. Therefore, it is only 4 square roots of 2.

That side is also the hypotenuse in the 45 45 90 triangle. To find the leg, we simply divide by the square root of 2. We will end of with legs that are 4.

The population of wild horses on a wildlife refuge decreased from 110 to 99 in a year. If this trend were to continue, what exponential equation could be used to predict the horse population in the future?
y = 110(1.1)^x
y = 99(0.9)^x
y = 99(1.1)^x
y = 110(0.9)^x,

Answers

The exponential equation for this situation is y = 110(0.9) ^x. This is because 110 is the principal or the initial number of horses and y is the resultant population after a certain number of years X with a rate of 0.9.  Note that the rate is less than 1 which means that the population is decreasing as time goes by.

The area of each triangular face is

Answers

first you should find that how much 15% of 240 is:
[tex] \frac{15}{100} = \frac{x}{240} \\ x = \frac{240 \times 15}{100} = \frac{3600}{100} = 36 [/tex]

Determine how many, what type, and find the roots for f(x) = x4 + 21x2 − 100.

Answers

Answer:

Step-by-step explanation:

We will make a substitution to make our work easier (when we get there).  We also need to know that

[tex]i^2=-1[/tex]

We will use that as another substitution.  First, let's make the job of factoring a bit easier.  Here's the first substitution.  We will let

[tex]x^4=u^2[/tex]

Therefore,

[tex]x^2=u[/tex]

Now we will write the polynomial in terms of u instead of x:

[tex]f(x)=u^2+21u-100[/tex]

Solve for the values of u by setting the polynomial equal to 0 and factoring.  When you factor, you will get:

[tex](u+25)(u-4)[/tex]

But don't forget that

[tex]x^2=u[/tex]

so we have to put those back in now:

[tex](x^2+25)(x^2-4)=0[/tex]

By the Zero Product Property, either

[tex]x^2+25=0[/tex] or

[tex]x^2-4=0[/tex]

We will factor the first term.  Solving for x-squared gives us:

[tex]x^2=-25[/tex] and

x = ±√-25

which simplifies down to

x = ±√-1 × 25

we can sub in an i-squared for the -1:

x = ±√[tex]i^2*25[/tex]

The square root of i-squared is "i" and the square root of 25 is 5, so

x = ±5i

The next one is a bit easier.  If

[tex]x^2=4[/tex], then

x = ±2

You can see you have 4 solutions.  But you knew that already, since this is a 4th degree polynomial.  The types of solutions are:  2 real, 2 imaginary

Answers

Answer: Question 1.1: It is 1.5 standard deviations away from the mean.

Our value of 26 is 6 units about the mean of 20. If each standard deviation is 4, we just divide 6 by 4. This gives us the number of standard deviations.

Question 2.2 The correct answer is -0.52

If we are 0.52 standard deviations below the mean, then our z-score is simply -0.52. The definition of a z-score is the number of standard deviations from the mean.

A person invested $7,200 in an account growing rate allowing money to double every 8 years. How much money would be in the account after 19 years, to the nearest dollar?

Answers

What is the formula for exponential growth?

The formula for exponential growth:

In this case, the initial amount is $7,200, the rate is 2 (since the money doubles every 8 years), and the number of time periods is 19/8=2.375 (since 19 years is 2.375 times the 8-year doubling period). Plugging these values into the formula, we get:

Which equation represents a direct variation?

y = 2x
y = x + 4
y =1/2x
y = 3/x

Answers

The answer is y = x + 4 because both x and y are being multiplied by the same thing.  They both have a coefficient of 1.  When ever the same number is being multiplied or divided by both x and y, it is considered a direct variation.  This means the coefficients would be the same.

Answer:

A. [tex]y=2x[/tex]

Step-by-step explanation:

We are asked to find the equation that represents a direct variation.

We know that a direct variation is in form [tex]y=kx[/tex], where y is directly proportional to x and k is constant of variation.

Upon looking at our given choices, we can see that equation [tex]y=2x[/tex] represents direct variation, where [tex]k=2[/tex].

It takes Susan 3 hours to fix 2 broken cars and it takes Joseph 4 hours to fix 3 broken cars. If they work together how long will it take them to fix 17 broken cars?

Answers

combined rates

Susan = 2 car / 3 hr
= 2/3

Joe = 3 car / 4 hr
= 3/4

add the rates to get the new combined rate as 17 cars in "t" hours.

2/3 + 3/4 = 17/t

Need common denominator

2/3(4/4) + 3/4(3/3) = 17/t

8/12 + 9/12 = 17/t

17/12 = 17/t

see that "t" is 12 hours
Final answer:

Susan and Joseph can fix 17 broken cars together in 12 hours.

Explanation:

To calculate the time it takes for Susan and Joseph to fix 17 broken cars together, we can calculate their individual rates of work.



Susan takes 3 hours to fix 2 cars, so her rate is 2/3 cars per hour.



Joseph takes 4 hours to fix 3 cars, so his rate is 3/4 cars per hour.



When they work together, their rates are additive. So their combined rate is (2/3 + 3/4) cars per hour. This is equal to (8/12 + 9/12) cars per hour, which simplifies to 17/12 cars per hour.



To find the time it takes to fix 17 cars, we can divide the number of cars by the combined rate: 17 cars / (17/12 cars per hour) = 12 hours.

You won't find such a logarithm function on your calculator, but that isn't a major problem since you can easily convert a logarithm from any base to any other base by simply dividing by the logarithm of the desired base. So:
5.5^(3x) = 805
log(5.5^(3x)) = log(805)
log(5.5^(3x))/log(5.5) = log(805)/log(5.5)
log to base 5.5 of 5.5^(3x) = log(805)/log(5.5)

Your friend wants to borrow $1,137.45 from you to pay off a credit card that charges a 14.7% APR. You agree to the loan but require your friend to pay you interest of 3.6% APR on the loan and your friend agrees.
Your friend pays you $200.00 at the end of the first month. How much goes toward the principal?

Answers

$196.59  
Let's start by calculating the interest on the first month. 1137.45 * (0.036/12) = 1137.45 * 0.003 = 3.41235 
 So at the end of the 1st month, the amount owed will be 1137.45 + 3.41 = 1140.86 
 And after the 200 payment is done, the new balance will be:
 1140.86 - 200 = 940.86 
 Meaning that the principle reduced is: 1137.45 - 940.86 = 196.59 
 We could have also gotten the amount going towards the principle by subtracting the interest from the paying like: 200 - 3.41 = 196.59

The amount that goes into the principal when friend pays you $200.00 at the end of the first month is $296.56.

How to calculate the amount?

The first interest will be:

= 1137.45 × (0.036/12)

= 3.41

The amount owed at the month end will be:

= 1137.45 + 3.41

= 1140.86

The new balance after 200 payment will be:

= 1140.86 - 200

= 940.86

Therefore, the reduction in principal will be:

= 1137.45 - 940.86

= 196.59
