Answer:
k = 500 - a
Step-by-step explanation:
[tex]k + a = 500[/tex]
As we need "k" alone in one side of eqn. , we need to substract "a" on both the sides of the eqn. so that we can cancel "a" which on the left side.
[tex]k + a - a = 500 - a[/tex]

Calculate the a50 term of the geometric sequence with a28 = 3 and r = -1
Answer:
3
Step-by-step explanation:
multiplying by -1 only changes the number if you're multiplying an odd amount of times, but this time you're going from 28 to 50, so it's even, so the number stays the same.

Answer: 17) 41.0° 18) 60.8° 19) 36.0° 20) 19.7°
Step-by-step explanation:
Law of Cosines: a² = b² + c² - 2bc · cos A
b² = a² + c² - 2ac · cos B
c² = a² + b² - 2ab · cos C
17) a = 29, b = 13, c = 21, C = ???
c² = a² + b² - 2ab · cos C
21² = 29² + 13² - 2(29)(13) · cos C
441 = 841 + 169 - 754 cos C
441 = 1010 - 754 cos C
-569 = -754 cos C
[tex]\dfrac{569}{754}=\cos C\\\\\cos^{-1}\bigg(\dfrac{569}{754}\bigg)=C[/tex]
41.0° = C
18) a = 29.3, b = 25.7, c = 16.8, B = ???
b² = a² + c² - 2ac · cos B
25.7² = 29.3² + 16.8² - 2(29.3)(16.8) · cos B
660.49 = 858.49 + 282.24 - 984.48 cos B
660.49 = 1140.73 - 984.48 cos B
-480.24 = -984.48 cos B
[tex]\dfrac{480.24}{984.48}=\cos B\\\\\cos^{-1}\bigg(\dfrac{480.24}{984.48}\bigg)=B[/tex]
60.8° = B
19) a = 12, b = 19, c = 11, A = ???
a² = b² + c² - 2bc · cos A
12² = 19² + 11² - 2(19)(11) · cos A
144 = 361 + 121 - 418 cos A
144 = 482 - 418 cos A
-338 = -418 cos A
[tex]\dfrac{338}{418}=\cos A\\\\\cos^{-1}\bigg(\dfrac{338}{418}\bigg)=A[/tex]
36.0° = A
20) a = 10, b = 9, c = 18, A = ???
a² = b² + c² - 2bc · cos A
100² = 9² + 18² - 2(9)(18) · cos A
100 = 81 + 324 - 324 cos A
100 = 405 - 324 cos A
-305 = -324 cos A
[tex]\dfrac{305}{324}=\cos A\\\\\cos^{-1}\bigg(\dfrac{305}{324}\bigg)=A[/tex]
19.7° = A

If h(x) = -2x+5/4, find h(x) = 3/4
Answer:
x = 1/4
Step-by-step explanation:
We are given the function as h(x) = - 2x + 5/4. If we have to determine h(x) = 3/4 given this function, let's substitute this value into our function and solve for 'x.' This will be our solution -
3/4 = - 2x + 5/4,
If we subtract 5/4 from either side : - 2x = - 1/2
Now divide either side by - 2 : x = 1/4
Therefore our solution is x = 1/4
Answer:
[tex]x=\frac{1}{4}[/tex]
Step-by-step explanation:
So we have the function:
[tex]h(x)=-2x+\frac{5}{4}[/tex]
And we want to find h(x)=3/4.
So, we want to find the value of x such that h(x) equates to 3/4.
So, substitute 3/4 for h(x):
[tex]\frac{3}{4}=-2x+\frac{5}{4}[/tex]
First, subtract both sides by 5/4. The right will cancel.
[tex]\frac{3}{4}-\frac{5}{4}=-2x+\frac{5}{4}-\frac{5}{4}[/tex]
Subtract on the left:
[tex]-\frac{2}{4}=-2x[/tex]
Reduce on the left:
[tex]-\frac{1}{2}=-2x[/tex]
Now, multiply both sides by -1/2. The right will again cancel:
[tex]-\frac{1}{2}(-\frac{1}{2})=-\frac{1}{2}(-2x)[/tex]
Multiply on the left:
[tex]x=\frac{1}{4}[/tex]
So, for h(x) to be 3/4, the value of x is 1/4.
And we're done!

3w – 15
Factoring out the GCF
The factored form of 3w - 15, after factoring out the Greatest Common Factor, is 3(w - 5).
To factor out the greatest common factor (GCF) from the expression 3w - 15, we first need to determine the GCF of the two terms.
In this case, the GCF of 3w and 15 is 3. Both terms are divisible by 3.
To factor out the GCF, we divide each term by the GCF:
3w/3 - 15/3
Simplifying further, we have:
w - 5
Therefore, the factored form of 3w - 15, after factoring out the GCF, is 3(w - 5).
Factoring out the GCF is a process that involves identifying the highest common factor of all the terms in an expression and dividing each term by that factor. This helps simplify the expression and can make it easier to work with or further factorize if needed.
In this case, the GCF was 3, so we divided both terms by 3 to factor it out, resulting in the simplified expression w - 5.

Soccer ball specifications require a diameter of 8.65 inches with an allowable margin of error of 0.05 inch.
Use this information to complete these statements.
The equation that can be used to find d, the diameter of a new soccer ball, is
| ____ | = ____
The minimum possible diameter of a soccer ball is ____,
and the maximum possible diameter is ____
Answer:
Equation for new diameter: |d' - 8.65| ≤ 0.05
Minimum possible diameter = 8.60 inches
Maximum possible diameter = 8.70 inches
Step-by-step explanation:
We are told that:
Ball specifications require a diameter (d) = 8.65 inches.
Allowable margin of error = 0.05 inch
Now, since we have a value for the allowable margin of error, it means that the absolute value equation to determine the possible value or the new diameter (d') would be;
|d' - 8.65| ≤ 0.05
Minimum possible diameter = 8.65 - 0.05 = 8.60 inches
Maximum possible diameter = 8.65 + 0.05 = 8.70 inches

When writing a repeating decimal as a fraction, does the number of repeating decimal digits you use matter? Explain.
Answer:
No
Step-by-step explanation:
If you have a repeating decimal it doesn't matter who many decimal digits there are. Most repeating decimals I have encountered end up converting into a fraction that has a denominator of 9.
Hope This Helps :)
Answer:
It depends
Step-by-step explanation:
It depends on what the repeating decimal is. For instance if the decimal is a repeating 8 then you only have to use one digit. If, however, it is something like .673673673 going on forever you just need however many until it loops again. In this case you would need three, because that is how long the loop is.

Suppose we flip a fair coin n times. We say that the sequence is balanced when there are equal number of heads and tails. For example, if we flip the coin 10 times and the results are HT HHT HT T HH, then this sequence balanced 2 times, i.e. at position 2 and position 8 (after the second and eighth flips). In terms of n, what is the expected number of times the sequence is balanced within n flips?
Answer:
Step-by-step explanation:
Given:
fair coin is flipped n times
sequence is balanced when there are equal number of heads and tails
To find:
In terms of n, what is the expected number of times the sequence is balanced within n flips
Solution:
Let C(n,r) be the binomial co-efficient. The sample space has [tex]2^{n}[/tex]
Suppose that n is even because there are equal number of heads and tails and the number of heads and tails is not equal when n is odd.
As the result can be either head or tail so the probability of getting head is 1/2. So the number of these sequences with n/2 head is C(n,n/2) since we choose n/2 out of n to be assigned heads.
As every string sequence is equal chance of occurring so the probability is
C(n,n/2) / [tex]2^{n}[/tex]
