An airplane descends at a rate of 2,700 feet per minute. once the airplane starts its descent, what will be its change in elevation after 312minutes?

Answer:

B. slope: -1/2 , y-intercept: 1

rise over run. go down one, means a negative 1. too the right twice, means positive 2. y-intercept is obvious, it's just the point in which the line intercepts the y-axis.

Answer:

The basic technique to isolate a variable is to “do something to both sides” of the equation, such as add, subtract, multiply, or divide both sides of the equation by the same number. By repeating this process, we can get the variable isolated on one side of the equation.

Step-by-step explanation:

Answer:

1.) CIRCLE B

2.) 14 cm ; 7cm ; 154cm²

Step-by-step explanation:

Given that:

CIRCLE A:

Diameter (d) = 9cm

CIRCLE B:

Radius (r) = 5cm

Circumference of circle A:

Radius (r) = diameter / 2

C = 2 * pi * r = 2 * 3.14 * (9/2) = 28.26 cm

Circumference of Circle B:

C = 2 * pi * r = 2 * 3.14 * 5 = 31.4 cm

CIRCLE B has the larger Circumference.

2.) circle with Circumference (C) = 44cm

Diameter of circle ;

C = 2 * pi * (d/2)

44 = 2 * 3.14 * (d/2)

44 = 6.28d / 2

88 = 6.28d

d = 14.01 = 14.0 cm ( 1 decimal place)

B.) Circle's Radius

Radius = diameter / 2

Radius = 14.0 / 2 = 7 cm

C.) Area (A) of the circle :

A = pi * r^2

A = 3.14 * 7^2

A = 3.14 * 49

A = 153.86

A = 154 cm²

Answer:

x>-15/4

Step-by-step explanation:

1/3(6/8+1/2x)>-3/8

3/4 + 1/2 x>- 9/8

6+4x>-9

4x>-9-6

4x>-15

x>-15/4

This problem is incomplete, but applying the relation between velocity, distance and time, LeBron could find the flight with the fastest average speed dividing distance by time.

Velocity is distance divided by time, that is:

v = d/t.

Hence, to find the fastest flight, he needs the highest speed, which is found  dividing distance by time.

The ratio of the area of the smaller square to the area of the larger square, that have a perimeter ratio of 2:7 is 4:49

The ratio of the perimeter of the squares = 2 : 7

Required: The ratio of the area of the smaller square to the larger square.

Solution: The perimeter of a square of side x is 4•x

The comparative length of the side of each square are therefore;

Answer:

a) The slope of the line is [tex]-\frac{12}{5}[/tex]

b) The slope of the line is 1

Step-by-step explanation:

The rule of the slope of a line that passes through points (x1, y1) and (x2, y2) is m = [tex]\frac{y2-y1}{x2-x1}[/tex]

a)

∵ The line passes through points (-3, 4) and (2, -8)

∴ x1 = -3 and y1 = 4

∴ x2 = 2 and y2 = -8

→ Substitute them in the rule of the slope above to find it

∵ m = [tex]\frac{-8-4}{2--3}[/tex] = [tex]\frac{-12}{2+3}[/tex] =  [tex]\frac{-12}{5}[/tex]

∴ m = [tex]-\frac{12}{5}[/tex]

∴ The slope of the line is [tex]-\frac{12}{5}[/tex]

b)

∵ The line passes through points (5, -3) and (1, -7)

∴ x1 = 5 and y1 = -3

∴ x2 = 1 and y2 = -7

→ Substitute them in the rule of the slope above to find it

∵ m = [tex]\frac{-7--3}{1-5}[/tex] = [tex]\frac{-7+3}{-4}[/tex] = [tex]\frac{-4}{-4}[/tex]

∴ m = 1

∴ The slope of the line is 1

Plant B produces 6000 panels.

Given that, Plant A produces 18,000 panels out of 2% are defective and 6% of the panels produced by Plant B are defective.

Defective percentage : It is the number of defects divided by the sample size, multiplied by 100. So, if one tool is defective out of a sample size of 1,000, your percent defective is 0.1 percent.

No. of Defective Panels from Plant A + No. of Defective Panels from Plant B = Total No. of Defective panels

Let No. of Panels produced from Plant A = A and No. of Panels produce from Plant B = B

2% of 18000 + 6% of B = 3% of (18000 + B)

360 + 0.06*B = 0.03( 18000 + B)

360 + 0.06* B = 540 + 0.03*B

0.06*B - 0.03B = 540-360

0.03*B = 180

 3B = 18000

B = 6000

CHECK:

2% of 18000 + 6% of 6000 = 360+360 = 720 defectives

18000 + 6000 = 24000

720 out of 24000 = 720/24000 = 72/2400 = 3%

Hence, Plant A produces 18000 panels and 2% of them , or 360, are defective.

Plant B produces 6000 panels and 6% of them,  or 360, are defective.

The compound interest is Rs8275

Step-by-step explanation:

The rule of the compound interest is A = P[tex](1+\frac{r}{n})^{nr}[/tex], where

The interest I = A - P

∵ The amount of investment is Rs25000 for 3 years

∴ P = 25000

∴ t = 3

∵ The rate of interest is 10% per annum, compounded annually

∴ r = 10% = 10 ÷ 100 = 0.1

∴ n = 1 ⇒ compounded annually

→ Substitute these value in the 1st rule above to find the new amount

∵ A = 25000[tex](1+\frac{0.1}{1})^{1(3)}[/tex]

∴ A = 25000[tex](1.1)^{3}[/tex]

∴ A = Rs33275

→ Use the 2nd rule above to find the interest

∵ I = 33275 - 25000

∴ I = 8275

∴ The compound interest is Rs8275

It's option 2

Step-by-step explanation:

parallel to the x-axis basically means that it mirrors the x-axis since parallel lines have the same slope. since the question wants the graph with the line that is also below the x-axis, the correct graph would be option 2

Answer:

Option 2 is parallel to the x axis because only option 1 and 2 are a line across and option 1 is 3.2 units above.

Answer:

it is not EWTD compliant

Step-by-step explanation:

Given that :

Directive = maximum average working hours per week = 48 hours

Engagement :

9:00 - 18:45 = (9 hrs 45 mins) - 30 mins = 9hrs 15 mins

9 hrs 15 mins for 3 days = 27 hours 45 mins

10:30 - 21:00 = (10 hrs 30 mins) - 45 mins = 9 hrs 45 minutes

Sundays (10:00 - 14:00) = 4 hours

Total work hours per week :

2(9hrs 15 mins) + 3(9hrs 45 mins) + 4 hours =;

18 hrs 30 mins + 29 hrs 15 minutes + 4 hours

(18 + 29 + 4) + 45 minutes

51 hours 45 minutes.

51 hours 45 minutes > 48 hours ; a Hence, it is not EWTD compliant

y= 1/3 x -1 so thhe y-intercept is at point (0, -1)

to find the x-intercept make y=0

x/3  -1 =0

x/3  =1

x= 3 so x-intercept is at point (3, 0)

Answer:

 D. The slingshot reaches a greater height at 150 feet, which is the vertex of the parabola.

Step-by-step explanation:

First let's examine the given equations

[tex]\displaystyle \rm\\(x -70)^2 + (y-77)^2 = 5184 ............. (1)\\y = -4x^2 + 40x + 50 ............... (2)[/tex]

Equation (1) is of the form of a standard equation for a circle
[tex]\displaystyle \rm (x-a)^2 + y-b)^2 = r^2\\\\[/tex]

where (a, b) is the center of the circle and r is the radius

Equation (2) is the standard equation of a parabola
y = ax² + bx + c where a, b and c are constant

So we know that the Ferris wheel motion is circular while the slingshot motion is parabolic

Let's compute the highest point at which the Ferris wheel reaches.

Given,  

[tex]\displaystyle (x-70)^2 + (y-77)^2 = 5184[/tex]
We can see that r² = 5182 by comparing it to the circle equation[tex]\displaystyle x_v=-\dfrac{40}{2\left(-4\right)}[/tex]

Therefore r = √5184 = 72. The diameter = 144 which is the highest point vertically from the center of the circle

The highest point on the circle = 144 + 5= 149 m since there is a 5' gap between the Ferris wheel and the ground at the lowest point so that has to be taken into account

For the parabola the vertex is the highest point and its x-coordinate given by   [tex]\displaystyle \dfrac{-b}{2a}[/tex]    in the standard equation for a parabola

Comparing the given equation with the standard equation we see that a = -4, b = 40 and c= 50

Therefore [tex]x_v[/tex] the x-coordinate of the vertex:
[tex]\displaystyle x_v=-\dfrac{40}{2\left(-4\right)} = 5[/tex]

The y coordinate of the vertex can be found by plugging in this value into the parabolic equation

[tex]\displaystyle y_v=-4\cdot \:5^2+40\cdot \:5+50 = 150[/tex]

This being the vertical coordinate of vertex of the parabola, the highest point that the slingshot reaches is 150'

So correct answer is D
