  c.  10^2

Step-by-step explanation:

It can be helpful to remember that an exponent signifies repeated multiplication. Here, the denominator factors cancel an equal number of numerator factors

  [tex]\dfrac{10^6}{10^4}=\dfrac{10\cdot10\cdot10\cdot10\cdot10\cdot10}{10\cdot10\cdot10\cdot10}=10\cdot10=\boxed{10^2}[/tex]

Answer:

x = 1, x = 6

Step-by-step explanation:

Given equation:

[tex]\dfrac{x+2}{x-4}=\dfrac{2x}{x-3}[/tex]

Cross multiply:

[tex]\implies (x+2)(x-3)=2x(x-4)[/tex]

Expand brackets:

[tex]\implies x^2-3x+2x-6=2x^2-8x[/tex]

[tex]\implies x^2-x-6=2x^2-8x[/tex]

Collect and combine like terms:

[tex]\implies 2x^2-x^2-8x+x+6=0[/tex]

[tex]\implies x^2-7x+6=0[/tex]

Factor:

[tex]\implies (x-6)(x-1)=0[/tex]

Therefore,

[tex](x-6)=0\implies x=6[/tex]

[tex](x-1)=0 \implies x=1[/tex]

Answer:

5,2,2,2,2.

Step-by-step explanation:

2×2×2×2×5=80

Answer:

Option (5)

Step-by-step explanation:

Lina's speed during the first part of the trip = s miles per hour

If she travels initial 80 miles on this trip with this speed, time taken to cover the distance [tex]t_1=\frac{\text{Distance}}{\text{Speed}}=\frac{80}{s}[/tex] hours

Now speed at which she traveled remaining 50 miles = (s + 10) miles per hour

So the time spent to cover this distance  [tex]t_2=\frac{50}{s+10}[/tex] hours

Total time for the complete trip = [tex]t_1+t_2[/tex] = [tex]\frac{80}{s}+\frac{50}{s+10}[/tex]

= [tex]\frac{80(s+10)+50s}{s(s+10)}[/tex]

= [tex]\frac{80s+800+50s}{s(s+10)}[/tex]

= [tex]\frac{130s+800}{s(s+10)}[/tex]

Therefore, Option (5) will be the answer.

Option C is correct. The expressions that represent the total time of her trip in hours is [tex]t_1 + t_2 = \frac{80}{s} +\frac{50}{s+10} \\[/tex]

Let the speed travelled during the first part of the trip be "s"

The formula for calculating the distance is expressed as:

[tex]distance=speed\times time[/tex]

For the first part of the journey:

distance = 80miles

time = t₁

Speed = s

Substitute the given parameters into the formula:

[tex]80 = st_1\\t_1=\frac{80}{s}[/tex]........................................... 1

For the second part of the trip;

Distance travelled = 5 miles

speed = s + 10 (10miles/hour faster than the first part of the trip)

time = t₂

Get the time  t₂

[tex]50=(s+10)t_2\\t_2=\frac{50}{s+10}[/tex]

Adding both times taken to get the total time of her trip in hours.

[tex]t_1 + t_2 = \frac{80}{s} +\frac{50}{s+10} \\[/tex]

Hence the expression that represent the total time of her trip in hours is [tex]t_1 + t_2 = \frac{80}{s} +\frac{50}{s+10} \\[/tex]

Answer:

The technician can combine 10 liters of pure acid with 30 liters of 20% acid to get the desired concentration

Step-by-step explanation:

For pure acid, the concentration will be 100%

Let the liters of pure be a and the liters of 20% be b

Since we want 40 liters of total;

a + b = 40 ••••••••(i)

Also,

100% of a + 20% of b = 40% of 40

a + 0.2b = 16 •••••(ii)

From ii , a = 16-0.2b

Put this into i

16-0.2b + b = 40

0.8b = 40-16

0.8b = 24

b = 24/0.8

b = 30

Since a + b = 40

a = 40 - b

a = 40-30

a = 10

The time taken for the light to reach earth will be 3.6 ×10⁴ hours. The quantity of time that an activity or a condition continues to exist. is known as the time period.

The amount of time that an action or a state continues to exist. is the time period. Depending on the nature of the activity or situation under consideration, it might be measured in seconds or millions of years.

The given data in the problem is;

v is the speed of ultraviolet light= 3 ×10⁸ m/sec

d is the distance covered by the light= 4×10¹³ Km=4× 10¹⁶m

The  time taken by the light to reach the surface of the earth will be;

[tex]\rm d = v\times t \\\\ \rm t= \frac{d}{v} \\\\ \rm t= \frac{4\times 10^{16}}{3\times 10^8} \\\\ \rm t= 1.33 \times 10^{8} \ sec[/tex]

In one hour there are 3600 seconds so the time period in the hours is found as;

[tex]\rm t= 1.33 \times 10^8 \times \frac{1}{3600} \\\\ \rm t=3.6 \times 10^4\ hours[/tex]

Hence the time taken for the light to reach earth will be 3.6 ×10⁴ hours.

Line B has a positive slope and a positive y-intercept because crosses the y-axis above the origin.

As per the shown graph,

In line A, we move from left to right along the line, and the y-values decrease. This means line A has a negative slope.

In line B, we move from left to right along the line, and the y-values increase. This means line B has a positive slope.

Similarly, line C has a positive slope.

Here, lines A and B cross the y-axis above the origin (positive y-intercept)

Thus, line B has a positive slope and a positive y-intercept.

Answer:

B the range of f (-00,-4)

Answer:

A and D

Step-by-step explanation:

A is correct as x must be any real number to yield a proper f(x) value.

B is incorrect, as a value of x=0 would mean f(x) = 0 which is outside the listed range.

C is incorrect as the equation is a quadratic (highest exponent is ^2) which forms a parabola shape on a graph and therefore does not infinitely decrease.

D is correct. To find a maximum or turning point, we can take the derivative of the function and set it to 0, as the slope at any turning point will always be 0:

f'(x) = -8x

0 = -8x

x = 0

So, the maximum occurs where x=0

f(x) = -4x^2

f(x) = -4(0)^2

f(x) = 0

This means the y-value is also 0, meaning that (0,0) is our maximum.

E is incorrect. Since the maximum is only just on the x-axis (0,0) it only touches the x-axis once so it only has one x-intercept.

13

Step-by-step explanation:

The missing statements are skewed left, Outlier, score and scores; range; scores.

1. This distribution of test scores is skewed left.

  The distribution is skewed left because the tail of the boxplot extends to the left, indicating that there are more lower scores in the dataset.

2. The test score of 23 is an outlier.

  The value 23 is an outlier since it lies outside the whiskers of the boxplot. An outlier is a data point that is significantly different from the rest of the data.

3. The median test score is 61.5.

The median is the value that separates the data into two equal halves. Since the line divides the box at 61.8, the median is 61.5.

4. The range of all the test scores is

After placing 1 at both extremes ;

Each two successive digits in row 6 are summed up;

Row 6: 1, 6, 15, 20, 15, 6, 1.

(1 + 6) = 7;

The magnitude, M, of an earthquake is 1.544 units when the magnitude of an earthquake is 1,000 times more intense than a standard earthquake

It is given that the magnitude of m, of an earthquake, is defined as:

[tex]\rm M=log\frac{I}{S}[/tex]

Where 'I' is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and 'S' is the intensity of a "standard" earthquake.

It is required to find the magnitude of the earthquake that is 1,000 times more intense than a standard earthquake.

It is another way to represent the power of numbers and we say that 'b' is the logarithm of 'c' with base 'a' if and only if 'a' to the power 'b' equals 'c'.

[tex]\rm a^b=c\\\rm log_ac=b[/tex]

We have:

[tex]\rm M=log\frac{I}{S}[/tex]

and  [tex]\rm I=35S[/tex]  putting this value in the above equation, we get:

[tex]\rm M=log\frac{35S}{S}[/tex]

[tex]\rm M=log35[/tex]

[tex]\rm M=1.544[/tex]  (From log table)

Thus, The magnitude, M, of an earthquake is 1.544 units.

A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, line, or geometric figure.

Rotation in mathematics is a concept originating in geometry. Any rotation is a motion of a certain space that preserves at least one point. It can describe, for example, the motion of a rigid body around a fixed point.

Brick A rotated 90° to brick B.

Step-by-step explanation:

Menal wants to know the minimum number of pages, p, she must read during each of those 4 weeks to meet her goal.What is the inequality for this problem?

Total pages = 625

First week = 50 pages

Fifths week = 45 pages

First week + fifth week

= 50 + 45

= 95 pages

Total pages remaining = Total pages - pages read

= 625 - 95

= 530 pages

Total pages remaining = 530 pages

Pages per week for 4 weeks ≥ 530 pages / 4 weeks

p ≥ 132.5 pages
