Answer:
Angle A = Right angleAngle B = Obtuse angleAngle C = Acute angleStep-by-step explanation:
The little square symbol made in intersection point of two rays of angle A represents a right angle.
Angle B looks greater than Angle A but less than 180° (straight line) And Angle C looks smaller than Angle A but greater than 0 in measure.
Angle that lies between 0° and 90° = acuteAngle that measure 90° = rightAngle that lies between 90° and 180° = obtuseAnswer:
A. Right angle - it's is a right angle bcuz it's of 90° and perpendicular.
B. Obtuse angle - it's an obtuse angle bcuz it's more than 90°
C. Acute angle - it's an acute angle bcuz it's less than 90°

A billboard painter is using a pulley system to hoist a can of paint up to a scaffold at a rate of half a meter per second. The height of the can of paint as a function of time is given by h(t) = 0.5t + 8. Five seconds after he starts raising the can of paint, his partner accidentally kicks a paint brush off of the scaffolding, which falls to the ground. The height of the falling paint brush can be represented by h(t) = −4.9(t − 5)2 + 38. When does the brush pass the paint can? If necessary, round your answer to the nearest hundredth.
The value of the t in the linear equation is 10 approximately.
According to the statement
We have to find that the value of the t.
So, For this purpose, we know that the
The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line.
From the given information:
The equations are:
h(t) = 0.5t + 8.
h(t) = −4.9(t − 5) + 38.
Then
= 0.5t + 8
= −4.9(t − 5) + 38.
And
= 0.5t + 8
= −4.9t + 24.5 + 38.
And
= 0.5t + 8
= −4.9t + 62.5
Now,
Subtact the equations then
= 0.5t + 8 - (−4.9t + 62.5)
= 0.5t + 8 + 4.9t - 62.5
= 0.5t + 4.9t - 62.5+8
= 5.4t -54.5
Then
5.4t = 54.5
t = 54.5/5.4
t = 10.092.
So, The value of the t in the linear equation is 10 approximately.

Find the value of r so the line that passes through each pair of points has the given slope.
(r, 7), (3, 4), m = -3/5
The value of r so that the line passes through (r, 7), (3, 4) and slope of - 3 / 5 is - 2.
How to find the pair of point of a line using the slope?The slope of the line is given as m = - 3 / 5.
The pair of point are (r, 7)(3, 4).
Using slope intercept form equation is as follows:
y = mx + b
where
m = slopeb = y-interceptTherefore, using (3, 4) we will find the y-intercept
y = - 3 / 5 x + b
4 = -3 / 5 (3) + b
4 = - 9 / 5 + b
b = 4 + 9 / 5
b = 20 + 9/ 5
b = 29 / 5
Therefore, the equation of the line is as follows;
y = - 3 / 5x + 29 / 5
Hence, let's find r (r, 7)
7 = -3 / 5(r) + 29 / 5
7 - 29 / 5 = -3 / 5 r
35 - 29/ 5 = -3 / 5 r
6 / 5 = - 3 / 5 r
cross multiply
-15r = 30
divide both sides by -15
r = 30 / -15
r = -2
Therefore, the value of r is -2.

Your return on investment A is 4.5% and your return on investment B is 3%. If the total of your investment is $75,000, how much should you invest in each fund to obtain a return of 4%?
One has to invest $50000 in A and $25000 in B
Let x represent the investment in A and y represent the investment in B.
Total investment is $75,000 ( given )
hence x + y=$75,000 (from the above information)
x + y= 75,000 (equation 1)
Interest rate in A is 4.5 % and Interest rate in B is 3 %
now, 4% of $75000 = $3000
4.5x/100 + 3y/100 = $3000
= 4.5x+3y=300000 ( equation 2 )
Multiplying 3 to equation 1
which equals to 3x + 3y= 225000 ( equation 3 )
Solving equations: equation 2 & equation 3
4.5x+3y=300000 ( equation 2 )
3x + 3y= 225000 ( equation 3 )
(-) (-) = (-)
1.5x = 75000
x= 50000
substituting x= 50000 in equation 1 (x + y= 75,000)
50000 + y= 75,000

If angle 2 = 6x + 5 and angle 4 = 4x + 14, what is the value of angle 2? Round your answer to the hundredths place.
Answer:
32°
Step-by-step explanation:
Angles 2 and 4 are vertical angles, so they are congruent. That means that their measures are equal.
First, we set their measures equal to each other.
Then we solve the equation for x.
Then, we use the value of x to find the angle measure.
m<2 = 6x + 5
m<4 = 4x + 14
Set the measures equal.
6x + 5 = 4x + 14
Subtract 4x from both sides.
2x + 5 = 14
Subtract 5 from both sides.
2x = 9
Divide both sides by 2.
x = 4.5
m<2 = 6x + 5
m<2 = 6 × 4.5 + 5
m<2 = 27 + 5
m<2 = 32

Determine depreciation for the first year of the trucks useful life by the street wine in units of output methods if the truck is actually driven 16,000 miles.
Round to two decimal places.
The depreciation for the first year of the truck's useful life is $32,000.
The cost of the truck is $40000.
The useful time is 5 years.
The residual value is $5000.
Now, the depreciation is given as:
SLM depreciation = (Cost - Residual Value) / 5 years
Depreciation expense per year = ($40,000 - $5,000) / 5
Depreciation expense for the first year = $7,000
Now,
The depreciation expense per mile is the difference between cost and residual value divided by expected miles over the truck's life.
Depreciation expense per mile = (Cost - Residual Value) / Expected miles over truck's life.
Depreciation expense = Depreciation expense per mile × Miles driven
Therefore,
Depreciation expense per mile will be:
= ($40,000 - $5,000) / 15,000 miles = $2.33 or $2

Find the speed, in miles per hour, of the two drivers.
Charlie 50 miles per hour
Violet 60 miles per hour
It is given that the distance between Memphis and New Orleans is 395 miles. This means, the total distance both covered = 395 miles
Charlie drove for 5.5 hours and Violet drove for 2 hours. Let the speed of Charlie be x miles per hour. Since, the speed of Violet was 10 miles per hour faster than Charlies, the speed of charlie was (x + 10) miles per hour
Since, distance = speed × time
Distance covered by Charlie = 5.5x
Distance covered by Violet = 2(x + 10)
Altogether they covered 395 miles,
So,
395 = Distance covered by Charlie + Distance covered by Violet
395 = 5.5x + 2(x + 10)
395 = 5.5x + 2x + 20
375 = 7.5x

None of the above
Based on the information, the option that is a factor of x³ - 1331 is A. x - 11.
What are factors?It should be noted that factor simply means the number that divides another number. In contrast to multiples, which are multiplied by another number to produce particular numbers, factors are the numbers that split the supplied number exactly.
It should be noted that when we factor out 1331, we will get the values of 11 × 11 × 11. Therefore, it should be noted that the expression will become x³ - 11³.
Therefore, it should be noted that the formula that will be applied will be:
a³ - b³ = (a - b)(a² + an + b²)
Therefore, applying the formula illustrated will give:
x³ - 11³
= (x - 11)(x² + 11x + 11²)
= (x - 11)(x² + 11x + 121
Therefore, the option that is a factor of x³ - 1331 is x - 11.
