Mathematics

Answer:

5x^2. if I understand your symbolism.

Step-by-step explanation:

I assume the sequence is

4x (= 4x^1)

20x^3

100x^5

so, the difference/ratio of one element of the sequence to the next 5x^2.

this is what you must multiply one element with to get the next.

therefore, the next element after 100x^5 would be

500x^7.

What is an equation of the line that is parallel to y=3x-8 and passes through point (4,-5)?

kompoz [17]

The equation of the line that is // to the given equation MUST HAVE THE SAME SLOPE.

The slope of the hiven equation is the number next to x or 3.

See it?

We know the slope is 3 and one point is given.

We now use the point-slope formula to find the equation.

y - y_1 = m(x - x_1)

See picture. The answer is y = 3x - 7.

How do I solve this question?

g100num [7]

Answer:

$-7 \frac{1}{2}$

Step-by-step explanation:

$\frac{6 {x}^{ - 1} {y}^{ \frac{7}{2} } }{ \sqrt{16 {x}^{2} } {y}^{2} } \\ \\ = \frac{6 {x}^{ - 1} {y}^{ \frac{7}{2} } }{ \sqrt{(4 {x} {y})^{2} }}\\ \\ = \frac{6 {x}^{ - 1} {y}^{ \frac{7}{2} } }{ {4 {x} {y}}}\\ \\ = \frac{6}{4} {x }^{ - 1 - 1} {y}^{ \frac{7}{2} - 1 } \\ \\ = \frac{3}{2} {x }^{ - 2} {y}^{ \frac{5}{2} } \\ \\ equating \: it \: with \: \\ a {x}^{b} {y}^{c} \\ \\ \implies \\ a = \frac{3}{2} \\ \\ b = - 2 \\ \\ c = \frac{5}{2} \\ \\ abc = \frac{3}{2} \times ( - 2) \times \frac{5}{2} \\ \\ = - \frac{15}{2} \\ \\ =- 7 \frac{1}{2} \\$

Charles is reading about computers. He learns that a computer processor can perform one command in approximately 0.000000016

ella [17]

The number 0.000000016 is expressed in scientific notation is:

$1.6 \times 10^{-8}$

Solution:

Given that,

Charlie learns that a computer processor can perform one command in approximately 0.000000016 nanoseconds

We have to express in scientific notation

Step 1:

Given number is:

0.000000016

Move the decimal point in 0.000000016 until there is only one non-zero digit to the left of the decimal point

Here,

Move the decimal 8 places to the right to get 1.6

We have moved the decimal to left, therefore, exponent is negative

$1.6 \times 10^{-8}$

Thus the given number is expressed in scientific notation

Answer:

use a ratio

Step-by-step explanation:

you work 10 hours and make $25. How much do you earn per hour? (this is your unit rate.)
