negative 2 square root of 10 over 7

Step-by-step explanation:

Answer:

It's the second choice ⁶√2.

Step-by-step explanation:

Convert to fractional exponents:

√2 = 2^1/2

∛2 = 2^1/3

√2 / ∛2

= 2^1/2 / 2^1/3 = 2^(1/2-1/3)

= 2^(1/6)

Now change back to radicals:

= ⁶√2.

Answer:

X x 26= 26x +840

Step-by-step explanation:

Answer:

See below in bold.

Step-by-step explanation:

Linear model:

E = 24x + 840   where E is the  enrolment .

If there are 900 students then

900 = 24x + 840

24x = 900-840 = 60

For  E < 900 we have the inequality

24x < 60

x < 2.5

As we are dealing in years our answer is

x <  3 years .

Answer:

The fraction of the fans at the football game that wore both a team T-shirts and team hat is [tex]2\frac{1}{20}[/tex]

Step-by-step explanation:

Let

x----> total fans

we know that

[tex]8\frac{1}{5}x[/tex] ----> wore team T-shirts

Convert to an improper fraction

[tex]8\frac{1}{5}x=8\frac{8*5+1}{5}=\frac{41}{5}x[/tex]

Multiply by 1/4

[tex]\frac{41}{5}x*\frac{1}{4}=\frac{41}{20}x[/tex]

convert to mixed number

[tex]\frac{41}{20}x=\frac{40}{20}+\frac{1}{20}=2\frac{1}{20}x[/tex]

therefore

The fraction of the fans at the football game that wore both a team T-shirts and team hat is [tex]2\frac{1}{20}[/tex]

Final answer:

To solve the exponential equation 7^(3x-1) = 5^(x-1) using properties of common logarithms, we can take the natural logarithm (ln) of both sides. By expanding and isolating x, we can solve for x approximately as x ≈ 0.08.

Explanation:

To solve this exponential equation, you can take the natural logarithm of both sides. The natural logarithm (ln) cancels out the exponential function. So, taking the ln of both sides, we have:

ln(7^(3x-1)) = ln(5^(x-1))

Using the property of logarithms, we can bring down the exponents:

(3x-1)ln(7) = (x-1)ln(5)

Now, we can solve for x by isolating it. Let's expand the equation:

3xln(7) - ln(7) = xln(5) - ln(5)

Combining like terms:

3xln(7) - xln(5) = ln(7) - ln(5)

Factoring out x:

x(3ln(7) - ln(5)) = ln(7) - ln(5)

And finally, dividing:

x = (ln(7) - ln(5))/(3ln(7) - ln(5))

Using a calculator or a math software, we can approximate the value of x to the nearest hundredth to find:

x ≈ 0.08

The measure of angle K and angle L is 35 degrees and 105 degrees

In Triangle JKL the measure of angle J = 40 and the measure of angle L is 3 times the measure of angle K.

here we assume the angle K be x

So Angle L be 3x

Now

J + K + L = 180

40 + x + 3x = 180

40 + 4x = 180

4x = 180 - 40

4x = 140

x = 35 degrees

So, the angle K be 35 degrees

And, angle L should be 3(35) 105 degrees

Answer:

arc BG = 14°

Step-by-step explanation:

∠BMG = [tex]\frac{1}{2}[/tex] ( arc BG + arc JS) = 30

Multiply both sides by 2

arc BG + arc JS = 60, that is

arc BG + 46° = 60° ( subtract 46° from both sides )

arc BG = 14°

Answer:

arc BG= 14°

Step-by-step explanation:

It is given in the figure that  mJS = 46∘ and m∠BMG = 30∘.

If two chords intersect in the interior of a circle, then the measure of each angle formed is half the sum of the measures of its intercepted arcs. So,  

m∠BMG = 12 (mJS +mBG)

Substitute the given values and solve for mBG.

30∘ = 12 (46∘ + mBG)

Multiply by 2.

60∘ = (46∘ + mBG)

Subtract 46∘.

14∘ = mBG

Therefore, mBG = 14∘.

Answer:

20 bricks

Step-by-step explanation:

So if you multipy the dimentions given, you get 750 inches squred. You now take 15,000 and divide it by 750 to get 20. This is your answer.

A company makes 20 concrete bricks.

Given:

Find:

Solution:

A company makes concrete bricks shaped like rectangular prisms.

So, the volume of the brick = 15*10*5 = 750[tex]inches^{3}[/tex]

Now, to find how many bricks they make we have to divide 750[tex]inches^{3}[/tex] from 15000.

Number of brick = 15000/750 = 20

Hence, the number of bricks that the company makes is 20.

Answer:

The manufacturer will have no profit or loss when the selling price equals $200 or $100.

Step-by-step explanation:

The expression to model the monthly profit from sales of a new model of bicycle is

-x^2 + 300x -20,000

Let

f(x) -----> the monthly profit in dollars

x -----> s the selling price of one bicycle in dollars

[tex]f(x)= -x^{2}+300x-20,000[/tex]

we know that

The manufacturer will make no profit nor a loss when the profit is equal to zero

so

f(x)=0

[tex]-x^{2}+300x-20,000=0[/tex]

Multiply by -1 both sides

[tex]x^{2}-300x+20,000=0[/tex]

The formula to solve a quadratic equation of the form [tex]ax^{2} +bx+c=0[/tex] is equal to

[tex]x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}[/tex]

in this problem we have

[tex]a=1\\b=-300\\c=20,000[/tex]

substitute in the formula

[tex]x=\frac{300(+/-)\sqrt{-300^{2}-4(1)(20,000)}}{2(1)}[/tex]

[tex]x=\frac{300(+/-)\sqrt{10,000}}{2}[/tex]

[tex]x=\frac{300(+/-)100}{2}[/tex]

[tex]x=\frac{300(+)100}{2}=200[/tex]

[tex]x=\frac{300(-)100}{2}=100[/tex]

therefore

The manufacturer will have no profit or loss when the selling price equals $200 or $100.

To find the selling prices at which the manufacturer will make neither a profit nor a loss, set the profit expression equal to zero and solve for x, giving a selling price of $5.

To determine the selling prices at which the manufacturer will make neither a profit nor a loss, we set the profit expression equal to zero:

0 = 100x - (500 + 20x)

Solving for x, we get x = 5. This means the selling price for the bicycle to break even is $5.

Answer:

Step-by-step explanation:

The key here is that AB ║ EC. This makes arc AE have the same measure as arc BC. Since those have the same measure as AB and the three arcs together make a semicircle, each has measure 180°/3 = 60°.

Then the various arc measures are:

Then your answers are ...

a) AE = 60°

b) ∠ABD = (1/2)(DE +EA) = (1/2)(100° +60°) = 80°

c) ∠DFC = (1/2)(CD +EB) = (1/2)(80° + (60° +60°)) = 100°

d) ∠P = (1/2)(DA -AB) = (1/2)(100° +60° -60°) = 50°

e) ∠PAB = (1/2)(AB) = (1/2)(60°) = 30°

This expression is different from zero for all real numbers, since for [tex]x^2 +1[/tex] then [tex]x^2 =-1[/tex], there is no number in the real numbers whose square root is equal to -1.

Answer:

(−4, 12), (1, −3)

Step-by-step explanation:

y = −3x

x^2 −4 = y

so

x^2 −4 = −3x

x^2 + 3x - 4 = 0

(x + 4)(x - 1) = 0

x + 4 = 0; x = -4

x - 1 = 0; x = 1

when x = 1, y = -3(1) = -3

when x = -4, y = -3(-4) = 12

Answer

(-4 , 12), (1 , -3)

ANSWER

(−4,12), (1,−3)

EXPLANATION

The system has equations:

y=−3x

[tex] {x}^{2} - 4 = y[/tex]

We equate the two equations to get:

[tex] {x}^{2} - 4 = - 3x[/tex]

[tex]{x}^{2} + 3x - 4 = 0[/tex]

[tex]{x}^{2} + 4x - x - 4 = 0[/tex]

[tex]x(x + 4) - 1(x + 4) = 0[/tex]

[tex](x + 4)(x - 1) = 0[/tex]

[tex]x = - 4 \: or \: x = 1[/tex]

When x=1,

y=-3(1)=-3

when x=-4, y=-3(-4)=12

The solution is (1,-3) and (-4,12)
