Find the equation of a straight line which is perpendicular to the line
which
passes through the point (3, -2).
Answer:
I don't see the equation for the line, but I describe the process.
Step-by-step explanation:
Let's look for a line that has the form y=mx+b, where m is the slope and b the y-intercept (the value of y when x=0).
The slope of a perpendicular line is the negative inverse of the slope of the reference line. In this case the equation for the reference line is missing. If it is in the form y=mx+b, take the m value, invert it, and then give it a "-" sign. For example, if the line is y = 2x +1, the negative inverse of the slope of 2 would be -(1/2).
The new line will have this new slope [-(1/m)] to make it y = -(1/m)x + b.
To find b, use the given point of (3,-2) in the equation and solve for b:
y = -(1/m)x + b
-2 = -(1/m)*(3) + b
Then solve for b and you'll have the equation for the solution to the problem.

OC is the radius of the circle (O is the center of the circle).
AD is the tangent to the circle at point C
When a radius of a circle meets with a tangent of the same circle, the angle between them is 90°
<ACB = <ACO = 90°
<ABC = 180 - (<ACB + <BAC)
= 180-(90+40)
= 50
Look closely,
<ABC = x = 50°
.
.
Example 8Do same as Example 7
Join O to B to form OB, which is the radius of the circle.
<ABO= 90°
< BOA = 50°
<OAB= x+25= 180-(90+50)
x+25= 40°
x = 15°

Answer:
a) 17.6 ft
b) 81.8 mm
c) 9 cm
d) 12 in
Step-by-step explanation:
Use the formula: πd = circumference to solve this equation
so you need to double the radius to get the diameter.
a) 5.6π = 17.6 ft
b) 26π = 81.8mm
c) 56.5 / π = 18.0 cm / 2 = 9 cm
d) 75.4/ π = 24.0 cm / 2 = 12 in
Amy has conducted a one-tailed hypothesis test to see if the average starting salary for recent State University graduates is greater than $50,000. She calculated a test statistic of 2.06. Her sample consisted of 200 alumni. What is the p-value for Amy's result
Considering the situation described, the p-value for Amy's result is of 0.0203.
What are the hypotheses tested?At the null hypotheses, it is tested if the mean is not greater than $50,000, that is:
[tex]H_0: \mu \leq 50000[/tex]
At the alternative hypotheses, it is tested if the mean is greater, hence:
[tex]H_1: \mu > \leq 50000[/tex]
We are testing if the mean is greater than a value, hence we have a right-tailed test. Using a right-tailed test with t = 2.06 and 200 - 1 = 199 df, the p-value is of 0.0203.

Answer:
-7+4√3.
Step-by-step explanation:
6-4√3 / 6+4√3 Multiply top and bottom by 6-4√3:-
= (6-4√3)( 6-4√3) / (6+4√3)(6- 4√3)
= (36-24√3- 24√3+48) / (36-48)
= (36-48√3+48) / (-12)
= -3 +4√3 - 4
= -7 + 4√3.

A circular flower bed is 16m in diameter and has a circular sidewalk around it that is 3m wide. Find the area of the sidewalk in square meters. Use 3.14 for .PI
Answer:
Step-by-step explanation:
Given that the diameter of the flower bed is 17 m and the width of the side walk is 2 m for a total out side diameter of 21 m.
Total Area is pi *(D/2)^2 = 346.4 m^2
Now subtract the area of the 17 m diameter flower bed for the area of the sidewalk alone. 346.4 - (pi*(17/2)^2 = 346.4 - 227.0 = 119,4 m^2
Answer: 119,4 m^2
Step-by-step explanation:
The equation is area = p times r^2
8 times eight times 3.14 = 119,4 m^2
The numerator of a fraction is 19 less than the denominator of the fraction. GIve that the fraction 2/9 is obtained when 1 is subtracted from the numerator and 1 is added to the denominator, fing the original fraction.
Answer:
[tex]\frac{7}{26}[/tex]
Step-by-step explanation:
let x be the denominator of the fraction then x - 19 is the numerator , so
[tex]\frac{x-19}{x}[/tex] ← is the original fraction
subtrating 1 from the numerator and adding 1 to the denominator , then
[tex]\frac{x-20}{x+1}[/tex] = [tex]\frac{2}{9}[/tex] ( cross- multiply )
9(x - 20) = 2(x + 1) ← distribute parenthesis on both sides
9x - 180 = 2x + 2 (subtract 2x from both sides )
7x - 180 = 2 ( add 180 to both sides )
7x = 182 ( divide both sides by 7 )
x = 26
Then the original fraction is
[tex]\frac{26-19}{26}[/tex] = [tex]\frac{7}{26}[/tex]
A penquin dives at 18 feet per minute how many minutes does it take to
dive to -54 feet?
3 Minutes
30 Seconds
5 Minutes
4 Minutes
Answer:
5 minutes
Step-by-step explanation:
it dives at positive 18 feet in a minute
however in order to dive at -54 feet, it must dive -5 times
18-18-18-18-18= -54
and 1min =18feet
so it needs 5minutes for the 5times
OR
Let x=the time needed to dive at -54 feet's
so 1min=18
x= -54
-54=18x
dividing both sides by 18
-54/18=18x/18
x=-54/18
x=-5
however time cannot be negative
therefore x =5
this implies that the penguin dives at -54 feet in 5 minutes.

The area of a sector of a circle with a radius measuring 15 cm is 75(pi) cm2. What is the measure of the central angle that forms the
sector?
The sector of the circle is bounded by 2 radii, and the measure of the central angle that forms the sector is 120 degrees
How to determine the central angle?The given parameters are:
Area = 75π cm^2Radius, r = 15 cmThe area is calculated using
Area = α/360 * πr^2
So, we have:
α/360 * π * 15^2 = 75π
Evaluate the exponent
α/360 * π * 225 = 75π
Divide both sides by 75π
α/360 * 3 = 1
Multiply
α/120 = 1
Multiply both sides by 120
α = 120
Hence, the measure of the central angle that forms the sector is 120 degrees
