Please help with problem 29​

Answer:

x = 4

Step-by-step explanation:

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

m = (10 - -2)/(4 - 4) = 12/0

so slope is undefined

therefore the line is a vertical line, which is x = 4

It arrives 1 hour early in Kathmandu, if its average speed is increased by 5 km/h;

Average speed = 45 km/h;

Total time taken to arrive Kathmandu from Biratnagar = 10 hours

∴ Distance between Kathmandu and Biratnagar = Speed × Time

                                                                                    = 45 × 10

                                                                                    = 450 km;

If average speed is increased by 5 km/h, new average speed = 50 km/h;

New time to reach Kathmandu = Distance/ Time

                                                   = 450/50

                                                   = 9 hours;

It arrives 10 - 9 = 1 hour early in Kathmandu;

It should be noted that 16 divided by 2 2/3 is 6.

It should be noted that the information is to compute 16 divided by 2 2/3.

Therefore, this will be:

16 ÷ 2 2/3

= 16 ÷ 8/3

= 16 × 3/8

= 2 × 3

= 6

Therefore, the value is 6.

The quotient of the quantity (30 × 10⁻²⁴)/(5 × 10⁻²⁴)  is found out to be 6 × 10⁰.

For writing exceptionally large or extremely small numbers, scientific notation is comparable to shorthand. A process is limited to a number multiplied by ten rather than written in decimal form.

Now, as per the expressed equitation;

= (30 × 10⁻²⁴)/(5 × 10⁻²⁴)

Divide the numerator (30 × 10⁻²⁴) by denominator (5 × 10⁻²⁴) by the quotient.

= 6 × 10⁰

Step-by-step explanation:

The sampling process used by the school newspaper is convenience sampling.

Convenience sampling is the most popular kind of sampling that concentrates on gathering data from individuals (the sample) who are 'convenient' for the researcher to reach. With this sample strategy, researchers can choose subjects at random who are receptive to being contacted and participating in the study rather than selecting participants at random based on any set of criteria (such as demographic variables). This implies that one can locate your sample at any time and any place, such as among individuals in a mall, on the street, at work, or in an online community.

Answer: 4 times a number equals 2 plus 3 times a number

Step-by-step explanation: (NMA)

When, the coordinate a and b are colinear, and b lies between a and c, if ac=36, ab= 2x+4 and bc=4x+2, then the value of x is 5

Given,

The coordinates a and b are colinear.

The point b lies between a and c

Therefore,

ac = ab + bc

ac= 36

ab= 2x+4

bc= 4x+2

Substitute the values

36= 2x+4 + 4x+2

36= 6x+6

6x= 36-6

6x=30

x=5

Hence, when the coordinate a and b are co-linear, and b lies between a and c, if ac=36, ab= 2x+4 and bc=4x+2, then the value of x is 5

The necessary expression for calculating the average rate of change inside the given function f(x) is given using :

f'(x) = (f(9) - f(2))/7

It quantifies how significantly the function changed per unit on average over that time interval. The slope of the single direction connecting every interval's ends on the function's graph is used to calculate it.

As we can see, slope is another way of calculating the average change rate. The average rate of change is calculated by dividing the difference in the dependent  (y-term) by the difference inside the independent variable (x-term). The slope, as well as average rate of change are the same thing.

The function is given to f(x)

The interval is given to be [2,9]

Let a = 2 and b = 9

The expression which is used to determine the average rate of change in f(x) is given by

Step-by-step explanation:

The equation of a circle in the xy-plane is found as (x + 2)² + (y - 1)² = 5.

A circle is a two-dimensional closed figure in which the set of all points with in plane is equidistant from the a given point known as the "centre."

Circle Formula: (x - h)² + (y - k)² = r² ;

Where, (h, k) is the centre & r is the radius of the circle.

Use the distance formula for(-2, 1) and (0,2)

[tex]\begin{aligned}&r=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2} \\&r=\sqrt{(0+2)^2+\left(2-1\right)^2} \\&r=\sqrt{(2)^2+\left(1\right)^2}\end{aligned}[/tex]

Further simplifying;

r = √(4 + 1)

r = √5

Centre (h, k) = (-2, 1)   Radius (r) = √5.

(x - h)² + (y - k)² = r²

(x + 2)² + (y - 1)² = √5²

(x + 2)² + (y - 1)² = 5 is the equation of the circle.
