Step-by-step explanation:

-x² + 8x + 20 = b

-x² + 8x + 20 - b = 0

a = -1 ; b = 8 ; c = 20 - b

 There is no real roots.

So, b² - 4ac < 0

Plug in a, b and c values

8²- 4(-1)(20-b) < 0

When we multiply (-1) and (-4), we will get 4

64 + 4(20 - b) < 0

64 + 4*20 - 4b < 0

64 + 80 - 4b < 0

144  - 4b    < 0

Subtract 144 from both sides

-4b < -144

Divide both side by -4 and when we are dividing by (-4), < will change to >

b > -144/-4

b > 36

So, when value of b is greater than 36, the equation will have no real roots.

Changing the coefficient of x to 6 changes the meaning of expression as 5 is added to 6 times x

Solution:

Given that number 2 in the expression 5 + 2x is called the coefficient of x

We are asked to find what happens when changing the coefficient to 6 change the meaning of the expression

In the expression,

5 + 2x

This means 5 is added to 2 times x or 5 is added to twice of x

Number 2 is called coefficient of x

When we change this coefficient to 6, the expression becomes,

5 + 6x

So now the meaning of expression becomes,

5 is added to 6 times x

So changing the coefficient of x changes the meaning of expressionStep-by-step explanation:

I got it correct on Edge

The slack of activity B, given its duration of 12 days, earliest finish of 22 days, and latest start of 15 days, is -7 days.

Now, let's calculate the slack of activity B. Slack represents the amount of time an activity can be delayed without affecting the overall project schedule. Mathematically, slack can be calculated as the difference between the latest start (LS) and the earliest finish (EF) of an activity:

Slack = LS - EF

In our case, the latest start (LS) of activity B is 15 days, and the earliest finish (EF) is 22 days. Therefore, the slack of activity B can be calculated as follows:

Slack = LS - EF

Slack = 15 - 22

Slack = -7

The slack value of -7 indicates that activity B is already delayed by 7 days, considering the project schedule. Negative slack values imply that the activity is behind schedule, and any further delay will directly impact the project completion date.

Optically active compounds can rotate plane-polarized light in

A - Clockwise rotation

B - Counterclockwise rotation

C - Dextrorotatory

D - Levorotatory

Optically active compounds can rotate the plane of polarization of light, which can be either clockwise or counterclockwise. The direction of rotation is usually expressed as either dextrorotatory (abbreviated as +) or levorotatory (abbreviated as -), depending on whether the compound rotates the plane of polarization to the right or left, respectively.

For example, a compound that rotates the plane of polarization to the right (clockwise) is said to be dextrorotatory (+), while a compound that rotates the plane of polarization to the left (counterclockwise) is said to be levorotatory (-).

Therefore, A corresponds to clockwise rotation, B corresponds to counterclockwise rotation, C corresponds to dextrorotatory, and D corresponds to levorotatory.

Explanation:

We set up a cosine ratio, since we want to connect the adjacent and hypotenuse. Then we'll use the inverse cosine, which is also known as arccosine, to isolate the angle value.

This is what your steps could look like:

cos(angle) = adjacent/hypotenuse

cos(L) = LM/LN

cos(L) = 18/60

cos(L) = 0.3

L = arccos(0.3)

L = 72.542396876278 which is approximate

L = 72.54 degrees approximately

Answer:

190 inches squared

Step-by-step explanation:

You have to split the shape into two different rectangles. Then multiply 22 x 5 to get the area of the right rectangle. The area of this is 110 inches squared. Then you find the area of the other rectangle by solving (15-5) x 8. You get 80. Then add 80 + 110 to get 190.

Hope it helps!

Answer: 190 inches²

Step-by-step explanation:

Area of rectangle = L x W

                             = 15 x 8

                             = 120 inches

Area of smaller rectangle = L x W

                                           = 5 x (22 - 8 = 14)

                                           = 70 inches

Therefore, 120 inches + 70 inches = 190 inches²

2 gallons per hour must flow out at spout B in order to fill the drum in exactly 96 hours

If the rate of flow through spout A is 2 gallons per hour and the drum needs to be filled in exactly 96 hours, then the total volume that needs to be filled is 2 gallons/hour × 96 hours = 192 gallons.

To fill the drum in 96 hours, the same amount of liquid should flow out of spout B. Therefore, the rate of flow out of spout B should be 192 gallons / 96 hours = 2 gallons per hour.

Hence, 2 gallons per hour must flow out at spout B in order to fill the drum in exactly 96 hours.

The exact area of each hexagonal shape is 181.5sqrt(3) cm^2. Option B

To determine the exact area of each hexagonal shape formed by the equilateral triangles, we need to calculate the area of one equilateral triangle and then multiply it by the number of triangles that make up the hexagon.

The formula to calculate the area of an equilateral triangle is:

Area = (sqrt(3) / 4) * side^2

Given that the side of each tile measures 11 cm, we can substitute this value into the formula to find the area of one equilateral triangle:

Area = (sqrt(3) / 4) * (11 cm)^2

= (sqrt(3) / 4) * 121 cm^2

= 121sqrt(3) / 4 cm^2

Now, since the hexagon is formed by six equilateral triangles, we can multiply the area of one triangle by 6 to find the total area of the hexagon:

Hexagon Area = 6 * (121sqrt(3) / 4 cm^2)

= 726sqrt(3) / 4 cm^2

= 181.5sqrt(3) cm^2

Therefore, the exact area of each hexagonal shape is 181.5sqrt(3) cm^2.

The correct answer is B: 181.5√3 cm^2.
