5N^2=2^2 \times 5^{7} \times x^{8}

Solution:

Given a number N in product of its prime factors.

N=2 \times 5^{3} \times x^{4}

Now, express 5 N^{2} as a product of prime factors in index form.

Substitute 2 \times 5^{3} \times x^{4} in place of N.

5N^2=5\times(2 \times 5^{3} \times x^{4})^2

Use exponential rule: \left(a^{m}\right)^{n}=a^{m n}

Multiply the power 2 into the powers of factors of every number in the bracket.

5N^2=5\times2^2 \times 5^{6} \times x^{8}

Arrange like terms together.

5N^2=2^2 \times 5\times 5^{6} \times x^{8}

Use exponential rule: a^{m} \times a^{n}=a^{m+n}

5N^2=2^2 \times 5^{1+6} \times x^{8}

5N^2=2^2 \times 5^{7} \times x^{8}

Hence 5N^2=2^2 \times 5^{7} \times x^{8}.

F(x)=5x-3 find the domain and range
lakkis [162]

Answer:

Let's solve for f.

fx=5x−3

Step 1: Divide both sides by x.

fx

x

=

5x−3

x

f=

5x−3

x

Let's solve for x.

fx=5x−3

Step 1: Add -5x to both sides.

fx+−5x=5x−3+−5x

fx−5x=−3

Step 2: Factor out variable x.

x(f−5)=−3

Step 3: Divide both sides by f-5.

x(f−5)

f−5

=

−3

f−5

x=

−3

f−5

Answer:

x=

−3

f−5

Write an equation of a line that passes through the two given points. Your answer should be written in slope-intercept form.
Vladimir79 [104]

Answer:

y = x

Step-by-step explanation:

Find the slope using rise over run (y2 - y1) / (x2 - x1)

Plug in the points:

(y2 - y1) / (x2 - x1)

(-8 - 0) / (-8 - 0)

-8 / -8

= 1

So, the slope is 1.

Plug in the slope and a point into y = mx + b and solve for b:

y = mx + b

-8 = 1(-8) + b

-8 = -8 + b

0 = b

Plug in the slope and y intercept into y = mx + b

y = mx + b

y = 1x + 0

y = x

So, the equation of the line is y = x

Can someone help me with this, please? I will give brainliest. Ridiculous answers will get reported.
tatiyna

Answer:

The reasoning here is that the price should be based on the volume.

for a cylinder it's pi * r² * height

for a cone it's 1/3 * pi * r² * height

you'll notice that the formulas are the same, except that the cone is just one third of the cylinders volume.

so a fair price should be 70ct, ignoring packaging of course.
