Answer:

-2 is the y intercept

Step-by-step explanation:

this is because it is in the y=mx+b format so 5x=mx therefore b=-2 making -2 the y intercept

Answer:

Step-by-step explanation:

The y intercept is the value where x = 0

y = 5(0) - 2

The y intercept is (0,-2).

Answer:36

Step-by-step explanation:

The required first and smallest term of consecutive terms is 38.

Given that,

The average of five consecutive numbers is 38. The smallest number to be determined.

The average of the values is the ratio of the total sum of values to the number of values.

The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.

The average of five consecutive numbers is 38.
Let the middle value is a,
Series of 5 number can be given as = (a -2n) , (a-n) , a , (a+n) , (a+2n).
n = 5
Average = ( a-2n +a -n + a +a+n+ a+2n)/5
38 = 5a/5
a = 38
Now smallest and first term (n = 1)   = a - 2n
                                                     = 38 - 2(1)
                                                     = 36

Thus, the required first and smallest term of consecutive terms is 38.

Domain of the function is: 0 < x < 12.

Volume of the box =  4x(12-x)²cm^3

Volume is the measure of how much space a given substance takes up inside a closed, three-dimensional object. A cuboid's volume given by its length (l), breadth (b), and height (h) is as follows:

Side of square  = 24cm

(a) Volume of the box

Let the squares used to create a box have a side of "x" cm.

so,

length will be = 2(12 - x)

Width will be = 2(12 - x)

Hight will be = x

Volume of the Square box (V) = l x b x h

                                    =  2(12 - x) *  2(12 - x) * (x)

                                   = 4x(12-x)²cm^3

(b) The domain of the function V(x)

We see that:

x is length, x >0

x cm of the side's length of 24 cm are removed from both ends.

so that 2x<24

Domain of the function is: 0 < x < 12.

I understand that the question you are looking for is:

An open box of maximum volume is to be made from a square piece of material, 24 centimeters on a side, by cutting equal squares from the corners and folding up the sides.

If V is the volume in cubic centimeters and x is the height of the box in centimeters, find V in terms of x. Determine the domain of the above function

Answer:

-2

Step-by-step explanation:

We can use the slope formula

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

   = ( 8 -2)/(-4- -1)

   = (8-2)/(-4+1)

   = 6/-3

   = -2

Two terms between the 1st and the 4th in the given geometric sequence is 21 and 147.

The formula for the nth term in a geometric sequence is given by:

a(n) = a(1) . rⁿ⁻¹

Where:

a(1) = first term

r = common ratio

Parameters given:

a(1) = 3

a(4) = 1029

Substitute n  = 4 into the formula:

a(n) = a(1) . rⁿ⁻¹

a(4) = 3 . r³

1029 = 3 . r³

r³ = 1029/3 = 343

r = 7

Two terms between the 1st and the 4th term is a(2) and a(3).

In a geometric sequence, the following applies:

a(n) = a(n-1) . r

Hence,

a(2) = 3 . r

       = 3 . 7 = 21

a(3) = a(2) . r

       = 21 . 7 = 147

Answer:

37

Step-by-step explanation:

If you do the reverse equation, that is -72 divided by -4 which gives you 18. Then you add 19 to that 18 and you get 37.

Answer:

the answer is 37

Step-by-step explanation:

37 - 19 = 18

18 x -4 = -72

Answer:

3.5 hours

Step-by-step explanation:

Let us represent

The time spent walking as x

The time spent riding as y

Jim began a 146​-mile bicycle trip to build up stamina for a triathlete competition.​ Unfortunately, his bicycle chain​ broke, so he finished the trip walking. The whole trip took 5 hours.

Hence:

x + y = 5.... Equation 1

x = 5 - y

If Jim walks at a rate of 4 miles per hour and rides at 40 miles per​ hour,

The formula for Distance = Speed × time. Hence,

4 × x + 40 × y = 146 miles

4x + 40y = 146.... Equation 2

We substitute 5 - y for x in Equation 2

4(5 - y) + 40y = 146

20 - 4y + 40y = 146

Subtract 20 from both sides

20 - 20 - 4y + 40y = 146 - 20

- 4y + 40y = 146 - 20

36y = 126

y = 126/36

y = 3.5 hours

Since the time he spent raiding his bicycle is represented by "y", the amount of time he spent on the bicycle is 3.5 hours

The probability is 7/5.

A person is randomly selected from a group of 1000 people.

We have,

440 people use glasses and must wear them.

20 wear glasses but are not required to do so.

140 people who should wear glasses but don't

400 if you don't need to wear glasses, don't wear them.

Therefore, the probability that the person does not wear glasses while driving even though he or she needs to wear them is:

P ( he or she does not wear glasses and needs to wear them / Total number of people surveyed ) = 140 / 100

P = 14 / 10

P = 7 / 5

The probability that he or she drives without wearing eyeglasses despite the fact that they are required is 7 in 5.

the length of side OP of rhombus is 45 mm and PM + MN is equal to 90 mm.

We are given a rhombus MNOP

We know that, a rhombus is a quadrilateral in which there are 4 sides and all the sides are equal.

We are given the length of the side NO as:

NO = 45 mm

Now, we need to find the length of side OP.

OP = 45 mm ( as NO = OP)

Also, we need to find PM + MN

PM + MN = NO + NO ( as PM = MN = NO )

= 2 NO

= 2 × 45 mm

= 90 mm

Therefore, we get that, the length of side OP of rhombus is 45 mm and PM + MN is equal to 90 mm.
