Step-by-step explanation:
I am not sure what you mean. you don't round the intermediate numbers and results. only the final result.
you keep the irrational terms (like square root) like variable terms as they are and apply operations on them without actually expressing them as numbers.
only at the very last moment (when the final result is calculated) would you express them as actual number. and then you round the final result.
so, this is solved via Pythagoras :
c² = a² + b²
c being the Hypotenuse (the side opposite of the 90° angle), a and b are the legs.
in our case we have
BP² = BN² + NP² = 7² + sqrt(95)² = 49 + 95 = 144
you see ?
no need ever to bring the actual result of sqrt(95) into the picture. just keep it at sqrt(95) and do with it, what you would do with any actual number.
BP² = 144
BP = sqrt(144) = 12
so, we never had to deal with the actual irrational number.
we know how it is created, so we keep using that term to represent it.

Y=1/8x-1
-5x+4y= - 13
Answer:
(2.57, -0.07)
Step-by-step explanation:
To solve the system of equations, we can substitute the expression for y in the second equation:
-5x + 4(1/8x - 1) = -13
We can then simplify and solve for x:
-5x + (1/2)x - 4 = -13
-3.5x = -9
x = 2.57
We can then substitute this value of x back into the first equation to find the value of y:
y = 1/8(2.57) - 1
y = -0.07
So the solution of the system of equations is (x, y) = (2.57, -0.07)

-0. 4 kilometer for every 15 minutes
-0. 6 kilometer for every 20 minutes
As the value of the ratio of both the quantities are NOT same so the given values .
No, The two rates not form a proportion.
Now, According to the question:
Two ratios are equivalent, if the fractions corresponding to them are equivalent. Four quantities are said to be in proportion, if the ratio of the first and the second quantities is equal to the ratio of the third and the fourth quantities.
A proportion is an equation that sets two ratios at the same value. For instance, you might express the ratio as follows:
1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls) There are 1 in 4 boys and 3 in 4 girls. 0.25 are male (by dividing 1 by 4)
Now,
0. 4 kilometer for every 15 minutes equals to (0.4/15) = 0.026
So for every minute they travel 0.026km.
0. 6 kilometer for every 20 minutes equals (0.6/20) = 0.03

The given expression has sin A = BC/AC=36/85, cos A = AB/AC=77/85, tan A = BC/AB=36/77
How to find sin cos tan?In trigonometry, the values of sin, cos, and tan are the main functions we consider when solving trigonometric problems. Using these trigonometric values, the angles and sides of a right-angle triangle are calculated. In addition to sine, cosine, and tangent values, the other three significant values are cotangent, secant, and cosecant.
Normally, when calculating the sin, cos, and tan values for a triangle, the angles of 0°, 30°, 45°, 60°, and 90° are taken into consideration. These specific angles' values are easy to remember. What the trigonometric values are all about is knowing the standard angles for a specific triangle according to the trigonometric ratios (sine, cosine, tangent, cotangent, secant and cosecant).
We have, AB = 77 , BC = 36.and CA=85
When we consider the t-ratios of ∠A, we have
Base = AB = 77, Perpendicular = BC = 36, Hypotenuse = AC =85.
∴sin A = BC/AC=36/85 , cos A = AB/AC=77/85 , tan A = BC/AB=36/77

a cell phone company has three different production sites. five percent of the phones from site 1, 7% from site 2, and 9% from site 3 have been recalled due to unexpected shutdown issue. suppose that 60% of the phones are produced at site 1, 30% at site 2, and 10% at site 3. if a randomly selected cell phone has been recalled, what is the probability that it came from site 3 (write it up to second decimal place)?
So, the probability that a randomly selected cell phone that has been recalled came from site 3 is 2.5 or 25%.
We can use Bayes' theorem to calculate the probability that a phone that has been recalled came from site 3. Bayes' theorem states that:
P(A|B) = P(B|A) * P(A) / P(B)
where:
P(A|B) is the probability of event A occurring given that event B has occurred (in this case, the probability that a phone came from site 3 given that it has been recalled)
P(B|A) is the probability of event B occurring given that event A has occurred (in this case, the probability that a phone has been recalled given that it came from site 3)
P(A) is the prior probability of event A occurring (in this case, the probability that a phone came from site 3)
P(B) is the prior probability of event B occurring (in this case, the probability that a phone has been recalled)
So, in this case, we have:
P(site 3 | recalled) = P(recalled | site 3) * P(site 3) / P(recalled)
We know that:
P(recalled | site 3) = 9%,
P(site 3) = 10%
We also know that:
P(recalled) = P(recalled | site 1) * P(site 1) + P(recalled | site 2) * P(site 2) + P(recalled | site 3) * P(site 3)
= (5% * 60%) + (7% * 30%) + (9% * 10%) = 3% + 2.1% + 0.9% = 6%
So, we can now calculate the probability that a phone that has been recalled came from site 3 as:
P(site 3 | recalled) = (9% * 10%) / 6% = 0.15 / 0.06 = 2.5
So the probability that a randomly selected cell phone that has been recalled came from site 3 is 2.5 or 25%.

Question 32:
Write an equation in Slope-Intercept form for the
line that passes through (1,-3) and is parallel to
y+2 = 4(x-1)
The equation y+2 = 4(x-1) is already in slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept. In this equation, the slope is 4 and the y-intercept is -2.
For a line that is parallel to y+2 = 4(x-1), the slope (m) will be the same, which is 4.
To find the equation of a line that passes through a specific point (1,-3), we can use the point-slope form of a linear equation: y - y1 = m(x - x1)
So, using the point (1,-3) and the slope (4), we can write the equation as:
y - (-3) = 4(x - 1)
Simplifying this equation gives:
y + 3 = 4x - 4
Finally, we can write the equation in slope-intercept form by adding 4 to both sides and dividing both sides by 4:
y = 4x - 1
So the equation for the line that passes through (1,-3) and is parallel to y+2 = 4(x-1) is y = 4x - 1

If x is the same amount of length added to each side, write a function of x giving the length of each of the original sides. Use these functions to make a function for the area of the original lawn.
The function of x giving the length of each of the original sides would be [tex](x + 100) * (x + 60) = x^2 + 160x + 6000[/tex].
What is Function of x?
A function is a formula that expresses one variable in terms of another. The statement "y is a function of x" (denoted y = y(x)) states that y changes depending on the value of x.
The original length of each side of the lawn can be represented by the function x + 100, and the original width can be represented by the function x + 60.
To find the area of the original lawn, we can multiply the length and width functions.
So, the function for the area of the original lawn is:
[tex](x + 100) * (x + 60) = x^2 + 160x + 6000[/tex]
This is a quadratic function in x, whose leading coefficient is 1, and the value of x is the same amount of length added to each side of the lawn.
