Step-by-step explanation:
For parallel line:
slope of given line:
m=-1/2
Parallel lines have equall slopes:
required slope=-1/2
For perpendicular line:
m1×m2=-1
-1/2×m2=-1
m2=2
slope of perpendicular line=2

Answer:
Just substitue every 't' with -4
Step-by-step explanation:
g(-4) = 3*(-4)*(-4) + 2*(-4) + 1
g(-4) = 64-8+1
g(-4) = 57
Answer:
g(-4) is 41
Step-by-step explanation:
[tex]g(t) = 3 {t}^{2} + 2t + 1[/tex]
when t is -4, substitute -4 in place of t:
[tex]g( - 4) = 3 {( - 4)}^{2} + 2( - 4) + 1 \\ g( - 4) = 48 - 8 + 1 \\ g( - 4) = 41[/tex]

Define intersection of a line
Answer:
perpendicular lines
Step-by-step explanation:
Two lines intersect when they cross each other. ... The point where the lines intersect is called the point of intersection. If the angles produced are all right angles, the lines are called perpendicular lines. If two lines never intersect, they are called parallel lines.
Answer:
When two or more lines cross each other in a plane, they are called intersecting lines.

Keith earns $8.60 an hour and time-and-a-half for all hours over 40
hours. How much did he earn the week he worked 47.5 hours?
a. $344
b. $625.65
c. $109.65
d. $440.75
8.60 per hour x 40 hours = 344
Time and a half over 40 hours:
47.5-40 = 7.5 hours at time and a half:
7.5 x 8.60 x 1.5 = 96.75
Total pay : 344 + 96.75 = $440.75
Answer: d. $440.75

why is 8/4 a natural number but 7/4 is not ?
Step-by-step explanation:
if we divide 8/4 then it comes 2 which is natural number but when we divide 7/4 it comes 1.75 which comes in points
Answer:
8/4=2 7/4=1.75
Step-by-step explanation:
Natural numbers are whole numbers ex: 1,2,3,4,700 etc. However 1.75 is not a whole number which is why it is not a natural number

Find (fog)(x) when f(x)=2/x+3 and g(x)=1/2x
Any help is appreciated :)
Answer:
1st option
Step-by-step explanation:
To find (f ￮ g)(x) substitute g(x) into f(x) , that is
f([tex]\frac{1}{2x}[/tex] )
= [tex]\frac{2}{\frac{1}{2x}+3 }[/tex]
= [tex]\frac{2}{\frac{1+6x}{2x} }[/tex]
= [tex]\frac{4x}{1+6x}[/tex]
There are 1/3 pieces of pie left over on each
plate. How much pie is left over in total?
Answer:
3/3
Step-by-step explanation:
there are 3 plates and 1/3 on each plate is 3
1/3+1/3+1/3= 3/3
An entity can be divided in fractions or ratios. The total number of pie left over on N plates is [tex]\frac 13N[/tex]
Given that:
[tex]k = \frac13[/tex] --- the fraction left over
The total number of pie left over is
[tex]Total = \frac{1}{3} \times N[/tex]
Where N is the number of plates
So:
[tex]Total = \frac{1}{3} N[/tex]
For instance
If N is 6, the number of pie will be 2: i.e.
[tex]Total = \frac{1}{3} \times 6 = 2[/tex]
If N is 12, the number of pie will be 4: i.e.
[tex]Total = \frac{1}{3} \times 12 = 4[/tex]

You are a mechanic who is measuring the valve clearance on a motorcycle engine. The current clearance for one of the valves is 0.30 millimeter (mm). The clearance should be at least 0.18 mm and no more than 0.22 mm. The valve clearance is set by using a spacer that reduces the distance between the cam and the valve by the size of the spacer. Spacers are available in 0.04 mm increments, and the spacer currently in the motorcycle engine is 2.84 mm. Which of the following size spacers, in millimeters, should you use to achieve a correct valve clearance?
The 0.2 mm spacers will be utilized in order to achieve the correct valve clearance.
What is the valve clearance of a motorcycle?On motorcycle and automobile engines, valve clearances essentially refer to the gap or distance between the top of the valve stem and the camshaft that controls it.
The exhaust valves in an automobile engine release the burned gases, while the intake valves permit air and fuel into the cylinder.
Given that:
The current clearance = 0.3 mmThe clearance range is between = 0.18 mm - 0.22 mmThe available spacer = 0.04 mm incrementsThe current spacer is = 2.84 mmThe difference in between the current and clearance range is:
0.3 mm - 0.18 mm = 0.12 mm0.3 mm - 0.22 mm =0.08 mmHowever, for clearance to be positioned within 0.18 mm - 0.22 mm. The required spacers to be used are 0.04 mm, and 0.08 mm in conjunction with:
Clearance 0.3 = 3.14Clearance 0.18 = 3.02Clearance 0.22 = 3.06The mean value = 3.04
Therefore, for us to approach and get to the value of 3.02, the required spacers to be that must be added are:
2.84+0.04 2.882.84+0.08 2.922.84+0.12 2.962.84+0.16 3.002.84+0.2 3.04Therefore, we can conclude that the 0.2 mm spacers will be utilized in order to achieve the correct valve clearance.

Solve the equation.
-(x + 2) – 2x = -2(x + 1)
x = [?]
Answer:
x = 0
Step-by-step explanation:
-(x + 2) – 2x = -2(x + 1)
-x-2-2x = -2x-2
-3x-2 = -2x-2
-3x+2x = -2+2
x = 0
Answer:
x = 0Step-by-step explanation:
-(x + 2) – 2x = -2(x + 1)
=> - x - 2 - 2x = -2x - 2
=> - 2 + 2 = - 2x + 2x + x

A rectangular swimming pool with dimensions 12 meters by 18 meters is surrounded by a pavement of uniform width x meters. Find the area of the pavement, A, as a function of x.
9514 1404 393
Answer:
A = 4x² +60x
Step-by-step explanation:
The area of walkway along each of the sides is the product of side length and walk width x. The total for the four sides is ...
12x + 18x + 12x + 18x = 2x(12 +18) = 60x
There is a square of walkway at each corner whose dimensions are x by x, so the corner area is ...
4·x²
Then the total walkway area is ...
A = 4x² +60x
