Step-by-step explanation:

f(x)=5x+k

Let x =2

f(2) = 5*2 +k

f(2) = 10+k

We know f(2) = 14

14 = 10+k

Subtract 10 from each side

14-10 = 10+k-10

4 =k

We are given the function f(x) = 5x + k when k is a constant, x equals 2, and f(x) equals 14

Steps to solve:

14 = 5x + k; x = 2

~Substitute

14 = 5(2) + k

Answer:

3927 litres of oil to the nearest litre.

Step-by-step explanation:

The volume of the cylinder = π r^2 h

= π * 100^2 * 250.

When half full the volume is  

1/2 * π  * 100^2 * 250

=  3926991 cm^3     Dividing this by 1000:

= 3927 litres.

A cylindrical tank is half-full of oil.

There are 3928 liters of oil in the tank

Volume of cylinder is teh amount of material the cylinder holds.  Volume is the density of the cylinder.

Volume Formula :

[tex]volume = \pi r^2h[/tex]

Given the radius of the cylinder is 100cm

Height of the cylinder is 250 cm

Substitute all the values inside the formula

[tex]V=\pi (100)^2(250)\\V=2500000\pi[/tex]

Cylinder tank is half full of oil . To find half of the volume , we divide the volume by 2

[tex]V=2500000\pi\\Half - full = \frac{2500000}{2}\pi \\Half-full =3926990.817 cm^3[/tex]

Given that 1 litre= 1000cm^3

convert cubic centimeter to litres

[tex]1000cm^3= 1litre \\3926990.817 cm^3=\frac{3926990.817 }{1000} \\1250000 cm^3=3927.99 liters[/tex]

Answer:

Step-by-step explanation:

You can observe a representation of the problem in the image attached.

Notice that angle ABD and DBC are congruent.

Also, those angles are complementary, which means

[tex]\angle ABD + \angle DBC = 90\°[/tex]

And we know that [tex]\angle ABD = \angle DBC = x[/tex]

So,

[tex]x+x=90\°\\2x=90\°\\x=\frac{90\°}{2}\\ x=45\°[/tex]

Which means that [tex]\angle DBC = 45\°[/tex]

Therefore, the measure of angle DBC is 45°.

Answer:

< DBC is [tex]45^{0}[/tex]

Step-by-step explanation:

The line segment AB perpendicular to CB implies that a right angle is formed at point B. So that, AB and CB meets at B at [tex]90^{0}[/tex] to each other. Since the ray BD bisects <ABC, i.e it divides <ABC into two equal parts.

Thus,  

           [tex]\frac{90^{0} }{2}[/tex]  = [tex]45^{0}[/tex]

Therefore, < DBC = [tex]45^{0}[/tex]

and                  < DBC =  < ABD = [tex]45^{0}[/tex]

These two angles are said to be complementary angles. Complementary angles are set of two or more angles that add up to [tex]90^{0}[/tex].

The value of CT is 13x - 1.

A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.

The figure given below shows a line segment CT, where the length of line segment CT refers to the distance between its endpoints, C and T.

Given that J is the midpoint of CT

CJ = 8x-5 and JT = 5x+4

C______________J______________T

⇒ CT = CJ + JT

Since J is the midpoint of CT, So CJ = JT

⇒ CT = CJ + JT

Substitute the values of CJ = 8x-5 and JT = 5x+4 in the above equation,

⇒ CT= (8x-5)+(5x+4)

⇒ CT= 8x-5+5x+4

Rearrange the likewise terms, and apply the arithmetics operation,

⇒ CT = 8x + 5x - 5 + 4

⇒ CT = 13x - 1

Hence, the value of CT is 13x - 1.

Final answer:

To find the length of CT, solve the equation 8x-5 = 5x+4 to find x, then substitute the value of x into either CJ or JT to find the segment's length and double it.

Explanation:

The student is asking a geometry problem where they need to find the length of the segment CT given that J is the midpoint of CT with CJ being 8x-5 and JT being 5x+4. Since J is the midpoint, these two segments are equal in length, thus the equation to solve is 8x-5 = 5x+4.

To find the value of x, follow these steps:

Once x is found, substitute it back into either CJ or JT expression to find the length of one segment. Then, double that length to find CT, as CT is equal to 2 times CJ or 2 times JT.

Answer:

-(-7)=7

Step-by-step explanation:

the opposite of the Justine score (-7) = Meghan  score  (7)

-(-7)=7

Final answer:

The correct representation of Meagan's score as the opposite of Justine's is -(-7) = 7, which is option D, where the double negative results in a positive score.

Explanation:

The trivia game scenario presents a situation where Justine and Meagan end up with opposite scores, with Justine losing 7 points and Meagan gaining the opposite. To express this numerically, if Justine's score change is represented as -7, then Meagan's score, being the opposite, is the negation of Justine's score, which is -(-7). This negation flips the sign of Justine's score change, resulting in a positive 7 for Meagan. Therefore, the correct way to represent that “the opposite of Justine’s score was equal to Meagan’s score” is -(-7) = 7.

Answer:

14.4 lb

Step-by-step explanation:

In a see-saw in equilibrium, the torque generated by one side needs to be the same generated in the other side. The torque is calculated by the product between the mass and the distance to the center of the see-saw.

The torque generated by the child is:

T1 = 60 * 3 = 180 lb*feet

So, the torque generated by the weight needs to be higher than T1 in order to lift the child.

The lowest mass is calculated when the mass is in the maximum distance, that is, 12.5 feet from the center.

So, we have that:

T2 = 180 = mass * 12.5

mass = 180/12.5 = 14.4 lb

So the lowest weight is 14.4 lb

The concept of leverage acting through a see-saw requires a balancing of forces on either side of the fulcrum. By calculating the torque from the child's weight and distance from the fulcrum, we can estimate the minimal weight needed on the other side to lift the child. The answer is approximately 14.4 lbs when placed 12.5 feet from the fulcrum.

The concept being explored here is leverage, specifically in the context of a see-saw. The see-saw operates on the principle of a basic lever where the two sides are balanced around a pivot point known as the fulcrum.

The input force, or effort, is defined by the weight of the child and the distance from the fulcrum they are sitting, while the output force, or resistance, is the weight needed on the other side to lift the child off the ground.

Here's how you calculate it: the child's weight of 60 lbs is 3ft from the fulcrum. So, the torque, or turning force, created by the child is 60lbs x 3ft = 180 lb-ft. Since we're looking for balance, the weight needed to lift the child would produce the same amount of torque. Technically, that could be achieved with a number of combinations of weight and distance, but given that the question asks for the smallest weight, the weight needs to be placed at the furthest available distance from the fulcrum, which would be half the length of the see-saw (12.5 feet). So, the weight would be 180 lb-ft / 12.5 ft = 14.4 lbs.

Final answer:

A set of symbols expressing a mathematical rule is called a mathematical model or equation, using variables and relationships to define concepts such as a set or a group in group theory.

Explanation:

A set of symbols that expresses a mathematical rule is often referred to as a mathematical model or equation. These models are essential for describing phenomena in a precise and universal language that transcends natural language, allowing for consistent replication and understanding across various fields of study. In mathematics, we use variables like x, y, or n and symbols to create equations which express relationships or rules. For example, to define a set of all even numbers, we could write the rule as the set of all real numbers x such that x/2 is an integer. This uses the structure of the equation to convey the membership rule for the set, which in this context would be described by the notation '{x : x/2 is an integer}' where the colon represents 'such that'.

Furthermore, when these symbols and rules are organized into a specific system with defined properties, such as closure, identity, inverses, and associativity, they can form a group, which is a fundamental concept in group theory.

Answer:

27 gallons, 2 quarts

Step-by-step explanation:

The measurements are given in gallons and quarts. Lets convert everything to quarts.

We know:

4 quarts = 1 gallons

So,

Rain Barrel Capacity = 47*4  + 1 = 189 quarts

Jiko uses 12 gallon  2 quart to water flower garden = 12*4  + 2 = 50 quarts

Jiko uses 7 gallons 1 quarts to water trees = 7*4  + 1 = 29 quarts

He used up = 50 + 29 = 79 quarts

Remaining Water in Rain Barrel = 189 - 79 = 110 quarts

In gallons and quarts:

27 * 4 = 108 quarts

So, water left = 27 gallons, 2 quarts

Answer:

both rates of change equal the slope of the line (3/4)

Step-by-step explanation:

Part a)

We calculate the rate of change using the formula:

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

for the first interval [0,6], we calculate the y-values at x=0 and x=6;

at x=0 : [tex]y=\frac{3}{2} (0)+2=2[/tex]

at x=6 : [tex]y=\frac{3}{2} (6)+2=11[/tex]

therefore, the rate of change in this interval is: [tex]\frac{y_2-y_1}{x_2-x_1}=\frac{11-2}{6-0}=\frac{9}{6} =\frac{3}{2}[/tex]

For the second interval [-4,4], we calculate the y-values at x=-4 and x=4;

at x=-4 : [tex]y=\frac{3}{2} (-4)+2=-4[/tex]

at x=4 : [tex]y=\frac{3}{2} (4)+2=8[/tex]

therefore, the rate of change in this interval is: [tex]\frac{y_2-y_1}{x_2-x_1}=\frac{8-(-4)}{4-(-4)}=\frac{12}{8} =\frac{3}{2}[/tex]

Part b):

Notice that both rates of change equal the value of the slope of the linear function (3/2)

Answer: 35

Step-by-step explanation: It's an arith metic sequence that can be represented throigh the equation y= 65-5x where 5 is the amount of hous since 4pm and if you insert 6 for x you get 35

The mathematics problem involves subtraction, where the temperature drops 5 degrees per hour from 4pm to 10pm. The equation to represent this would be 65 - 5*6 = T. After performing the calculation, we find the temperature at 10pm is 35 degrees Fahrenheit.

In this problem, you are dealing with a decline in temperature over time, which is considered as a subtraction problem. Since the temperature drops by 5 degrees every hour from 4pm to 10pm, that's a total of six hours (10pm - 4pm = 6 hours), so you'll subtract 5 degrees 6 times from the initial temperature of 65 degrees.

The equation to represent this problem is:

65 - 5*6 = T

This means you are subtracting 5 degrees six times from the initial temperature of 65 Fahrenheit to get the temperature (T) at 10pm. So, the calculation would be:

65 - (5*6) = 65 - 30 = 35

So, the temperature at 10pm is 35 degrees Fahrenheit.
