2. Give the degree of x2 - 17x + 2x - 5.00

Answer:

30

Step-by-step explanation:

1/2 x (a+b) x h = area

1/2 x ( 40 + x ) x 50 =  1750

1/2 (40 + x )= 1750/50

20 + 1/2x = 35

1/2 x = 35 - 20

x = 15 x 2

= 30

I hope this is right :)

Answer:(60 + 12)(60 – 12)

Step-by-step explanation:

Answer:

x = 7

y = 4

Arc JKL = 262°

Step-by-step explanation:

Find the diagram attached

Using the theorem;

Sum of opposite angle of the quadrilateral is 180°

7x+131 = 180

7x = 180-131

7x = 49°

x = 49/7

x = 7

Similarly;

11x+y+99 = 180°

11(7)+y+99 = 180°

77+99+y = 180

176+y = 180

y = 180-176

y = 4

arc JKL is the obtuse angle at the centre

Arc JKL = 360-(angle at the centre)

Angle at the centre is twice angle at the circumference.

Angle at the centre = 2(7x)

Angle at the centre = 2(49)

Angle at the centre = 98°

Arc JKL = 360-98

Arc JKL = 262°

Answer:

4.734 * 10^-5 miles

Step-by-step explanation:

Given that:

Distance between House to movie theater = 3 inches

Expressing the distance in miles :

Converting inch to miles

1 inch = 1.578 * 10^-5 miles

3 inches = (3 * 1.578*10^-5)

3 inches = 4.734 * 10^-5 miles

The solution to the system of equation is (7, 2)

Using the simultaneous equation:

5x + 3y = 41

2x + 3y = 20

using elimination method

Subtract equation 1 from 2 to have:

5x - 2x = 41 - 20

3x = 21

x = 21/3

x = 7

Substitute x = 7 into equation 1 to get y

5x + 3y = 41

5(7) + 3y = 41

35 + 3y = 41

5y = 41 - 35

3y = 6

y = 6/3

y = 2

Hence the solution to the system of equation is (7, 2)

Answer:

D I dont know if im right though

Step-by-step explanation:

The system of equations are same and graphs of the equations are the same line because the equations have the same slope and same y-intercept. The system has infinitely many solutions.

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

The first equation is -3x + 3y = 12  be equation (1)  

y = x + 4   be equation (2)

Adding 3x on both sides , we get

3y = 3x + 12

Divide by 3 on both sides , we get

y = x + 4   be equation (3)

So , the equation ( 2 ) is same as equation ( 3 )

Now , the slope of the equation is m = 1 and the y intercept is b = 4

Hence , the equations have infinite solutions

Answer: r = 1.69 inches

              h = 2.15 inches

Step-by-step explanation: Volume of a solid is the amount of space contained within a solid.

Volume of a cone is directly proportional to radius and height:

[tex]V=\frac{1}{3}\pi r^{2}h[/tex]

They want the cones to hold the same volume of 9 cubic inches.

If height is 3:

[tex]9=\frac{1}{3}\pi r^{2}3[/tex]

[tex]\pi r^{2}=9[/tex]

[tex]r^{2}=2.864[/tex]

r = 1.69 inches

When height is 3, radius is 1.69 inches for a cone to have 9 cubic inches of volume.

If radius is 2:

[tex]9=\frac{1}{3}\pi (2)^{2}h[/tex]

[tex]h=\frac{9(3)}{4 \pi}[/tex]

h = 2.15 inches

If radius is 2 inches, height of the cone is 2.15 inches.

Answer:

15 ft

Step-by-step explanation:

At 15 feet below the surface, the scuba diver did his safety stop.

The surface is the common region between two different mediums. Here in the question surface is the common region between seawater and above seawater.

Let us denote the values of descending by negative sign and rising by positive sign and we sum up all the values together.

∴ [ - 80 + 25 + (-12) + 52 ] feet.

= (-80 + 25 - 12 + 52) feet.

= - 15 feet.

So, at 15 feet below the surface the scuba diver dis his safety stop.
