whats the value of 4/5 x 3/4 in simplest form
The value of 4/5 x 3/4 in simplest form is 3/5. To find the value of 4/5 x 3/4, we need to multiply the numerators and denominators separately and simplify the resulting fraction to its simplest form. Multiplying the numerators 4 and 3 gives us 12, while multiplying the denominators 5 and 4 gives us 20. So, 4/5 x 3/4 can be written as 12/20.
To simplify 12/20 to its simplest form, we need to find the greatest common factor (GCF) of the numerator and denominator. In this case, both 12 and 20 are divisible by 4, so the GCF is 4. Dividing both the numerator and denominator by 4, we get 3/5. Therefore, the value of 4/5 x 3/4 in simplest form is 3/5.
In conclusion, the value of 4/5 x 3/4 in simplest form is 3/5, which can be obtained by multiplying the numerators and denominators separately and simplifying the resulting fraction by finding its greatest common factor.

11. What is the domain of the function? Please show how you solved it and explain.
Answer:
domain: \(x\leq -7, x\geq 3\)
Step-by-step explanation:
\(f(x)=\sqrt{x^2+4x-21}\)
Factor \(x^2+4x-21\):
\(x^2+4x-21=(x-3)(x+7)\)
Therefore,
\(f(x)=\sqrt{(x-3)(x+7)}\)
\(\implies f(x)=\sqrt{(x-3)}\sqrt{(x+7)}\)
Find non-negative values for radicals:
\(\sqrt{(x-3)} \implies x\geq 3\)
\(\sqrt{(x+7)} \implies x\leq -7\)
Therefore, domain: \(x\leq -7, x\geq 3\)
What is the equation of the line in slope-intercept form?
Answer:
5/2; 5
Step-by-step explanation:
The first box is m, which is the slope. To find the slope you do rise over run, so basically the change in x and y. You move up 5 and over 2, so m would be 5/2.
The second box is b, which is the y-intercept. To find the y-intercept, you just find where the line crosses the y-axis. That would be 5

A. Y=30x + 20
B. Y=75x + 30
C. Y=30x + 75
D. Y= 30x
Find the sum of each finite series. Σ¹° n = 5 (20-n)
The sum of the given finite series is 75
The given series is:
\(\sum\limits^{10}_{n=5} {(20-n)}}\)
To find the sum of this series,
Expand the summation notation by using the properties of sum operator:
Σ(a+b) = Σa + Σb
Hence,
\(\sum\limits^{10}_{n=5} {(20-n)}=\sum\limits^{10}_{n=5} {20}-\sum\limits^{10}_{n=5} {n}\)
If a is a constant, then Σa = k. a, where k is the number of terms = upper limit - lower limit + 1
Using this property:
\(\sum\limits^{10}_{n=5} {20} = (10 - 5+1)\times20=6\times20=120\)
Expand
\(\sum\limits^{10}_{n=5} {n}=5+6+7+8+9+10=45\)
Hence,
\(\sum\limits^{10}_{n=5} {(20-n)}=\sum\limits^{10}_{n=5} {20}-\sum\limits^{10}_{n=5} {n}\)
= 120 - 45 = 75

In a research experiment a population of files is increasing according to the law of exponential growth y(t) = aebt where a and b are constant and t is the number of days after 2 days there are 200 files and after 4 days there are 400 files. How many flies will there be after 6 days?
Answer:
After 6 days, there will be approximately 691.6 files.
Step-by-step explanation:
We can use the given information to solve for the constants a and b in the exponential growth equation. First, we can rearrange the equation to solve for b:
y(t) = aebt
ln(y(t)) = ln(aebt)
ln(y(t)) = ln(a) + ln(ebt)
ln(y(t)) = ln(a) + bt
Now, we can use the information given in the problem to solve for b. After 2 days, there are 200 files, so we can use the following equation to solve for b:
ln(200) = ln(a) + 2b
After 4 days, there are 400 files, so we can use the following equation to solve for b:
ln(400) = ln(a) + 4b
We can solve this system of equations using elimination method. Subtracting the first equation from the second equation gives:
ln(400) - ln(200) = 4b - 2b
ln(2) = 2b
b = ln(2)/2
Now that we have found the value of b, we can plug it back into one of the original equations to solve for a. Let's use the equation for 2 days:
ln(200) = ln(a) + 2b
ln(200) = ln(a) + 2(ln(2)/2)
ln(200) = ln(a) + ln(2)
ln(200) - ln(2) = ln(a)
ln(100) = ln(a)
a = 100
So now we have the values of a and b, and we can use them to find the number of files after 6 days:
y(6) = 100e(ln(2)/2)(6)
y(6) = 100e(3ln(2))
y(6) = 100e(3 * 0.693)
y(6) = 100e2.079
y(6) = 691.6
Therefore, after 6 days, there will be approximately 691.6 files.
There are 691.6 flies after 6 days.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 9 is an equation.
We have,
y(1) = a\(e^{bt}\)
Now,
200 = a\(e^{2b}\)
Taking logs on both sides.
log 200 = log a + 2b log e
log 200 = log a + 2b _____(1)
Now,
400 = a\(e^{4b}\)
Taking logs on both sides.
log 400 = log a + 4b log e
log 400 = log a + 4b ______(2)
From (1) and (2) we get,
log 400 - log 200 = log a + 4b - log a - 2b
log (400/200) = 4b - 2b
log 2 = 2b
b = log 2 / 2 _____(3)
Now,
Putting (3) in (1) we get,
log 200 = log a + 2 x log 2 / 2
log 200 = log a + log2
200 = 2a
a = 100
Now,
y(t) = 100 \(e^{(log2/2)t\)
Now,
t = 6
y(60) = 100 \(e^{log2/2 \times6}\)
y(60) = 100 \(e^{3log2}\)
y(60) = 100 \(e^{3\times0.69}\)
y(60) = 100 \(e^{2.079}\)
y(6) = 691.6
Thus,
There are 691.6 flies.

g thompson and thompson is a steel bolts manufacturing company. their current steel bolts have a mean diameter of 145 millimeters, and a variance of 49.if a random sample of 34 steel bolts is selected, what is the probability that the sample mean would be less than 143.5 millimeters? round your answer to four decimal places.
The probability that the sample mean would be less than 143.5 millimeters is 0.1695.
The p-value is a quantitative value that allows us to determine whether a null hypothesis (or claimed hypothesis) is true. Determining the p-value allows us to determine whether we should reject or not reject a claimed hypothesis. We set the significance level, which serves as the cutoff level, for whether a hypothesis should be rejected or not. This cutoff point is also called the alpha level (α). Typical values for the alpha levels are 0.1%, 0.5%, 1%, 2.5%, 5%, 10%, 20%, 25%, and 40%.
If the p-value is less than α, then this represents a statistically significant p-value. This means that we can reject the claimed hypothesis. If the p-value is greater than or equal to α, we cannot reject the claimed hypothesis. To calculate the p-value, this calculator needs 4 pieces of data: the test statistic, the sample size, the hypothesis testing type (left tail, right tail, or two-tail), and the significance level (α).
n = 34
Mean = μ = 145 mm
Variance = σ² = 49
∴ Standard deviation = σ = √49 = 7
\(Z = \frac{value-mean}{standard deviation}\)
The probability required is the difference of the p-value of Z when X = 145 - 1.5 = 143.5 and when X = 145 + 1.5 = 146.5.
When X = 143.5:
z = x - μ/ σ = 143.5 - 145/ 7 = -1.5/7 = -0.2142
p-value is 0.4152
When X = 146.5:
z = x - μ/ σ = 146.5 - 145/ 7 = 1.5/7 = 0.2142
p-value is 0.5847.
The probability required is 0.5847 - 0.4152 = 0.1695
Thus, the probability that the sample mean would be less than 143.5 millimeters is 0.1695.

How are lines KL and MN related?
The lines intersect at point K.
The lines are parallel.
The lines are perpendicular.
The lines do not have slopes
Lines KL and MN are related is by the lines being perpendicular. Therefore, the correct option is C.
What are perpendicular lines?Perpendicular lines are lines that are formed when two lines meet each other at the right angle or 90 degrees. This property of lines is said to be perpendicularity.
If a line passes through two points, then the slope of the line is
\(\text{m}=\dfrac{\text{y}_2-\text{y}_1}{\text{x}_2-\text{x}_1}\)
From the given graph it is clear that coordinates of points on line KL are K(-8,2) and L(6,2).
The slope of line KL is
\(\text{m}_1=\dfrac{2-2}{6-(-8)} =0\)
The slope of line KL is 0, it means it is a horizontal line.
From the given graph it is clear that coordinates of points on line MN are M(-4,8) and N(-4,-6).
The slope of line MN is
\(\text{m}_2=\dfrac{-6-8}{-4-(-4)} =\dfrac{1}{0}\)
The slope of line MN is 1/0 or undefined, it means it is a vertical line.
We know that vertical and horizontal lines are perpendicular to each other. Therefore, the lines KL and MN are perpendicular to each other.
