Rewrite the expression in the picture in the form k times x^n.

Mathematics
1 answer:
pantera1 [17]3 years ago
3 0

Answer:

8 x^-2

Step-by-step explanation:

2 sqrt(x) * 4x ^ -5/2

Rewriting

2 x^1/2  * 4x ^ -5/2

2*4 = 8

x^1/2 * x^ -5/2  

We know a^b * a^c = a^(b+c)

x^ 1/2 * x^ -5/2 = x^ (1/2 -5/2 ) = x^ (-4/2) = x^-2

8 x^-2

Curtis rides his bike 9 miles one way then turns around and rides back. On the return trip, his speed is increased 20% because t
k0ka [10]

Answer:

The expression that represents his total time is given by "t = 7.5/s" where s is his speed against the wind.

Step-by-step explanation:

In order to solve this problem we will assign a variable to Curtis speed on the first leg of the trip, this will be called "s". Since the speed on the first part is "s" and the speed on the second part is 20% higher, then the speed on the second part is "1.2s". Each leg of the course is 9 miles long, therefore the time it took to go each way is given by:

time = distance/speed

First part:

t1 = 9/s

Second part:

t2 = 9/1.2s = 7.5/s

The expression for the whole course is the sum of each, so we have:

t = t1 + t2

t = 9/s + 7.5/s

t = (9 + 7.5)/s = (16.5)/s

Answer:

When you are finished with the experiment, complete the following data analysis and submit your answers.

Determine the volume of the box and the block.

Determine the ratio of the block to the box:

The volume of box=(L)(W)(H)

The volume of the block (L)(W)(H)

Multiply this number by 100 to turn it into a percent.

Complete this statement: The volume of the block is _____ percent of the volume of the box.

Determine the ratio of the number of hits to the number of shots:

(number of hits100 shots)

Multiply this number by 100 to turn it into a percent.

Complete this statement: The block was hit _____ percent of the time.

Compare the results of step 2 to the results of step 3. Are the percentages similar?

Write a conclusion discussing the following items:

Based on your findings, do you think Rutherford's hypothesis was reasonable?

Restate Rutherford's hypothesis and describe how you tested it.

State whether your results support the hypothesis. If they do not, can you suggest some error in experimental procedure (other than a general human error) that might explain it?

Finally, explain how this experiment confirms the nuclear model of the atom and the idea that most of the atom is empty space.

Use the given figure to find the length of FG
frutty [35]

Answer:

FG = 19

Step-by-step explanation:

The two sides of the triangle are equal since JG is a perpendicular bisector

FG = HG

5x-6 = 3x+4

Subtract 3x from each side

5x-3x -6 = 3x+4-3x

2x-6 =4

Add 6 to each side

2x-6+6 =4+6

2x = 10

Divide by 2

2x/2 = 10/2

x =5

We want to find FG

FG = 5x-6

FG = 5(5)-6

    = 25-6

    = 19
