Answers

Answer 1

Answer:

A: y=2x+4

B. 34° Celsius

Step-by-step explanation:

A:

Since the temperature goes up at a steady rate of 2 degres per minute, we can assume that 2 is our slope. Since the graph shows us that 4 is the y-intercept, we can substitute both the slope and y-intercept into the equation of a line, or y=mx+b. (m is our slope and b is our y-intercept.)

Doing so gives you:

[tex]y = 2x + 4[/tex]

B.

Using the above formula (y=2x+4), we can substitute x with 15 (since x is the minutes that pass).

Doing so gives you y=30+4, the sum of which is 34.

Therefore, the answer should be 34° Celsius.

The distance travelled by the object in meters is 65 meters.

How to find distance?

using the formula,

s = 1 / 2 (u + v)t

where

u = initial velocityv = final velocitys = distancet = time

Therefore, the distance can be found as follows;

s = 1 / 2 (6 + 20)5

s = 1 / 2 (26)5

s = 13(5)

s = 65 m

Therefore, the distance travelled by the object in meters is 65 meters.

Answers

The line which has a gradient of 6 is A. line A

To answer the question, we need to know what the gradient of a line is.

What is the gradient of a line?

The gradient of a line is its slope. It is given by m = Δy/Δx where

Δy = change in y and Δx = change in x.

How to find the line that has the gradient 6?

Now, to find the line that has the gradient of 6, we see that the gradient

m ∝ Δy and m ∝ 1/Δx.

So, for a high value of gradient, we need

a large change in y and a small change in x.

Also, since 6 is positive, the gradient for the line will be positive.

The only line that meets these criteria is line A.

So, the line which has a gradient of 6 is A. line A

Factoring polynomials is breaking them down to the products of other smaller polynomials.

How do I find the formula for the nth term in a sequence? Like for example the sequence:4,9,14,19 what is the next term?

Answers

Answer:

Step-by-step explanation:

Arithmetic sequence:

   a = first term = 4

   d = common difference =  second term - first term

       = 9 - 4

   d  = 5

[tex]\sf t_n =a +(n -1)*d[/tex]

   = 4 + (n - 1) *5

   = 4 + 5n - 5

    = 5n -1

Check; n= 1 ,  first term = 5*1 - 1 = 5 - 1 = 4

           n = 2,  second term = 5*2 - 1 = 10 -1 = 9

           n = 3, third term = 5*3 - 1 = 15 - 1 = 1

The next term, fifth term  = 5*5 - 1

Step-by-step explanation:

a probability is always desired cases / total cases.

from the table and given information we know :

there are 40 blue counters.

0.25 = 40/x

x being the total number of counters in the box.

x = 40 / 0.25 = 160

the sum of all probabilities must be 1 (the always true probability), as there are only counters in the box, and one of the 4 colors is always the result.

so,

1 = 0.25 + 0.35 + 0.3 + red-probability

1 = 0.9 + red-probability

red-probability = 1 - 0.9 = 0.1

0.1 = red counters / 160

red counters = 0.1 × 160 = 16

there are 16 red counters in the box.

A body and tackle with a velocity ratio of 5 is used to raise a mass of 50kg through a vertical distance of 20n at a steady rate if the effort is equal to 80n. Determine (a) distance moved by effort (b)the workdone by the effort in lifting the load (c)the losses in energy involve the operating in machine

Answers

a. Distance moved by effort = 1 meter

b. Work done by effort = 80 Joules

c. Losses in energy = 18 Joules

How to determine the parameters

a. Note that velocity ratio is defined as the ratio of a distance through which any part of a machine moves to the distance moved by its parts

Velocity ratio = distance moved by the effort/distance moved by the body

Where velocity ratio = 5

vertical distance = 20cm

Distance moved by effort = 5 × 0. 20 = 1 meter

b. Formula for work done is given as ;

Work done = Effort × distance moved by effort

Work done = 80 × 1

Work done = 80 Newtons

c. First, let's find the work output

Work output = m g h

Work output = 50 × 9.8 × 0. 20

Work output = 98 Joules

Losses in energy = Work output - work done

Losses in energy = 98 - 80

Losses in energy = 18 Joules

Point X is the incenter of ΔABC.
Triangle A B C has point X as its incenter. Lines are drawn from the points of the triangle to point X. Lines are drawn from point X to the sides of the triangle to form right angles. Line segments X F, X G, and X E are formed.

If EX = 4z + 1, XF = 2z + 7, and mABC = 44°, find the following measures.

GX =

mABX = °

Answers

The value of GX is 13 and m ∠ABX is 22°

How to determine the angles

With the information, we have

EX = 4z + 1  and XF = 2z + 7

It is important to note that  EX = XF = GX are congruent, that is, they are equal

Equate EX = XF to determine z

4z + 1 = 2z + 7

Collect like terms

2z = 6

z = 3

We know that  EX = XF = GX and x = 3, substitute into the value of any one

EX = 4(3) + 1

EX = 13

EX = GX

GX = 13

To determine m ∠ABX, we divide m ∠ABC by 2

We have

m ∠ABX  = 44/2

m ∠ABX = 22°

Therefore, the value of GX is 13 and m ∠ABX is 22°

A tub contains red, yellow and blue counters. There is ten more yellow than red counters, and the ratio of red to blue counters is 3:4.If there are 20 blue counters, what is the probability of picking a yellow counter?

Answers

Answer:

5/12

Step-by-step explanation:

A ratio of 3:4 means that red counters make up 3/7 of the sum of red and blue counters and blue counters make up 4/7 of the total sum of red and blue counters.

If there is 20 blue counters, then 20 is 4/7 of the sum of the total red and blue counters.

So we need to solve for the total sum.

[tex] \frac{4}{7} x = 20[/tex]

[tex]4x = 140[/tex]

[tex]x = 35[/tex]

So the total amount of red and blue counters are 35,

So this means the amount of red counters is 15.

The amount of yellow counters is 25.

So the total number of counters are 60.

So P(Yellow counters)= 25/60= 5/12

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have two systems of the equation:

y = log (−5.6x + 1.3)

y  = −1 − x

After plotting the above equation on the graph we will see two intersections point:

(-2.12, 1.12) and (0.221, -1.221)

So the least value is x = -2.12 ≈ -2.1

The greatest value is x = 0.221 ≈ 0.2

Thus, from the least to the greatest, the solutions are x ≈ -2.1 and x ≈ 0.2

the answers are -2.1 and 0.2.
