Answer:
y=1/2x-3
Step-by-step explanation:
First, let's put the line into slope intercept form
2y+4x=12
subtract 4x from both sides
2y=-4x+12
divide by 2
y=-2x+6
the slopes of perpendicular lines are negative and reciprocal. If you multiply the slopes of the lines together, the result is -1. Therefore, to find the slope of the perpendicular line, use this formula:
-2m=-1
divide by -2
m=1/2
so the slope of the perpendicular line is 1/2
here is the new line so far:
y=1/2x+b (b is a place holder)
now, since the line passes through the point (8,1), it means that (8,1) is a solution of the line. So we can substitute it into the equation
1=1/2(8)+b
1=4+b
subtract 4 from both sides
-3=b
so the line is y=1/2x-3
Hope this helps!

If the standard deviation of shear strength measurements for spot welds is 9.5 pounds per square inch (psi), what is the minimum number of test welds that should be sampled if we want the sample mean to be within 1.4 psi of the true mean with probability approximately 0.99
Answer: 306
Step-by-step explanation:
Formula to find sample size:
[tex]n=(\dfrac{\sigma\times z^*}{E})^2[/tex] , where [tex]\sigma[/tex] = standard deviation, E = margin of error, z* = critrical z-value.
As per given,
[tex]\sigma=9.5 , E=1.4[/tex]
Critical z-value for 99% confidence = 2.576
Now , the minimum sampl size :[tex]n=(\dfrac{9.5\times2.576}{1.4})^2[/tex]
[tex]\Rightarrow\ n=305.5504\approx306[/tex]
Hence, the required sample size = 306
A plane flying at an altitude of 4 miles is approaching an airport that is 31 miles ahead on
the pilot's line of sight. What is the angle of depression from the plane to the airport to the
nearest TENTH of a degree?
Answer:
[tex]7.4^{o}[/tex]
Step-by-step explanation:
Altitude of the plane = 4 miles
Distance from the plane to the airport = 31 miles
Let the angle of depression from the plane to the airport be represented by θ. Thus applying the appropriate trigonometric function, we have;
Tan θ = [tex]\frac{opposite}{adjacent}[/tex]
= [tex]\frac{4}{31}[/tex]
= 0.1290
θ = [tex]Tan^{-1}[/tex] 0.1290
= 7.3506
θ = [tex]7.4^{o}[/tex]
The angle of depression from the plane to the airport is [tex]7.4^{o}[/tex].

A polygon is transformed according to the rule: (x, y)-(x + 2, y). Every point of the polygon moves two units in which direction?
Answer:
Every point of the polygon moves horizontal translation right '2' units
Step-by-step explanation:
Explanation:-
Type of transformation Change of co-ordinate point
Vertical transformation
up 'd' units (x, y ) → ( x , y +d)
Vertical transformation
down 'd' units (x, y ) → ( x , y -d)
Horizontal transformation
left 'c' units (x, y ) → ( x-c , y )
Horizontal transformation
right 'c' units (x, y ) → ( x+C , y )
Given that a polygon is transformed according to the rule: (x, y)-(x + 2, y)
∴ Every point of the polygon moves horizontal translation right '2' units

Step-by-step explanation:
In order to get the answer, I used the elimination/addition method
8y-9x= -3 <— I decided to eliminate the y
5y-8x= 10 <— I decided to eliminate the y
5(8y-9x = -3) <— switch up the number of y from the bottom to multiply
-8(5y-8x= 10) <— switch up the number of y from the top to multiply, but have a negative sign to it
So...our new equation will be....
40y - 45x = -15
+ -40y + 64x = -80
________________________
19x = -95
x = -5
8y-9x= -3
8y-9(-5) = -3
8y+45 = -3
- 45 = - 45
8y = -48
y = -6

Find the sum of the first 6 terms of the infinite series: 1 – 2 + 4 – 8 + . . .
Answer:
The sum of the first 6 terms of the inifinite series is -21.
Step-by-step explanation:
Following the sequence, we can see that each term is the previous term multiplied by -2. So, the first six terms are:
1, -2, 4, -8, 16, -32
The sum is:
1 - 2 + 4 - 8 + 16 - 32 = -1 - 4 - 16 = -21
The sum of the first 6 terms of the inifinite series is -21.
Answer:

Step-by-step explanation:
Buddy and his Step-brother Michael are in a snowball fight! They get hit by 85% of the snowballs.
If there were 200 snowballs thrown, how many were they hit by?
Answer: 170
Step-by-step explanation:
Since they get hit by 85% of the snowballs and there were 200 snowballs thrown, the number of snowballs that hit them will be gotten by multiplying 85% by 200. This will be:
= 85% × 200
= 0.85 × 200
= 170
Therefore, 170 snowballs hit them

Adrian invested $7,200 in an account paying an interest rate of 3.1% compounded
monthly. Assuming no deposits or withdrawals are made, how long would it take, to
the nearest year, for the value of the account to reach $12,110?
Answer:
17
Step-by-step explanation:
Adrian invested $7,200 in an account paying an interest rate of 3.1% compounded monthly. It takes 17 year for the value of the account to reach $12,110.
What is Compound interest?Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.
Compound Interest =P(1+r/n)^rt
Adrian invested $7,200 in an account paying an interest rate of 3.1% compounded monthly. for the value of the account to reach $12,110 we need to find the time it takes.
The principal amount = $7,200
Rate = 3.1%
Compound Interest = [tex]P(1+r/n)^{rt}[/tex]
12,110 = [tex]7200(1+3.1/12)^{3.1t}[/tex]
t = 17
Thus, for the value of the account to reach $12,110 the time taken is 17.

Estimate the average rate of change from x = 3 to x = 7.
Answer:
Average rate of change = 1.333 or 133.33%
Step-by-step explanation:
Given:
Base x = 3
New x = 7
Find:
Average rate of change
Computation:
Average rate of change = [new - base]/base
Average rate of change = [7 - 3] / 3
Average rate of change = 1.333 or 133.33%
