Answer:

12

Step-by-step explanation:

Pythag Theorem is Leg² + Leg²= Hypotenuse²

So I set it up as: x² + 9²=15²

Then solved and got: x² + 81 =225

Then I subtracted 81 on both sides and got: x² = 144

Then squareroot each side to undo the x² and got x=12

Find the ratio when partitioned by C

When BA is partitioned, the segments are: AC and CB

From the attachment:

[tex]AC = 3[/tex]

[tex]CB = 2[/tex]

So, the ratio is:

[tex]Ratio = AC : CB[/tex]

[tex]AC:CB = 3:2[/tex]

Answer:

[tex]Polynomial = 5x+ 2[/tex]

Step-by-step explanation:

Given

[tex]Weights = 3 + 4x[/tex]

[tex]Treadmill = 9x + 5[/tex]

Required

Polynomial that represents time spent running treadmill than weight lifting

To do this, we simply subtract weights from treadmill

i.e.

[tex]Polynomial = Treadmill - Weights[/tex]

[tex]Polynomial = 9x + 5 - (3 + 4x)[/tex]

[tex]Polynomial = 9x + 5 - 3 - 4x[/tex]

[tex]Polynomial = 9x - 4x+ 5 - 3[/tex]

[tex]Polynomial = 5x+ 2[/tex]

Answer:

50

Step-by-step explanation:

[tex]\boxed{distance \: between \: 2 \: points = \sqrt{(y1 - y2)^{2} + (x1 - x2) {}^{2} }}[/tex]

Distance between the 2 points

[tex] = \sqrt{( - 3 - 2) {}^{2} +( - 1 - 4) {}^{2} } [/tex]

[tex] = \sqrt{( - 5)^{2} + ( - 5)^{2} } [/tex]

[tex] = \sqrt{25 + 25} [/tex]

[tex] = \sqrt{50} [/tex]

Thus, the number that goes beneath the radical symbol is 50.

Answer:

Step-by-step explanation:

Answer:

The answer would be 150 degrees.

Step-by-step explanation:

When looking at the problem you can see that you have two parallel lines and a transversal. Since the two lines are parallel, this allows alternate interior angles to form, i.e. <A and <B.

Since angle A and B are alternate interior angles, you can now set the two equal to each other.

So, in order to find out what x equals, you have to set the two equations equal to each other.

8x-10=3x+90

Next, solve the new equation.

8x-10=3x+90

Add 10 to both sides.

8x=3x+100

Subtract 3x from both sides.

5x=100

Divide both sides by 5 and you'll get your answer.

x=20

Now that you know what x equals, you can substitute it into the equation for B.

<B= 3(20)+90

60+90= 150

<B=150 degrees

That gives you your answer of <B = 150 degrees.

To check your work you can also substitute x into the equation for <A.

<A= 8(20)-10

160-10= 150

<A=150 degrees.

Therefore, you have just proved that the answer is 150 degrees.

Given:

[tex]\log_34\approx 1.262[/tex]

[tex]\log_37\approx 1.771[/tex]

To find:

The value of [tex]\log_3\left(\dfrac{4}{49}\right)[/tex].

Solution:

We have,

[tex]\log_34\approx 1.262[/tex]

[tex]\log_37\approx 1.771[/tex]

Using properties of log, we get

[tex]\log_3\left(\dfrac{4}{49}\right)=\log_34-\log_349[/tex]      [tex]\left[\because \log_a\dfrac{m}{n}=\log_am-\log_an\right][/tex]

[tex]\log_3\left(\dfrac{4}{49}\right)=\log_34-\log_37^2[/tex]      

[tex]\log_3\left(\dfrac{4}{49}\right)=\log_34-2\log_37[/tex]          [tex][\log x^n=n\log x][/tex]

Substitute [tex]\log_34\approx 1.262[/tex] and [tex]\log_37\approx 1.771[/tex].

[tex]\log_3\left(\dfrac{4}{49}\right)=1.262-2(1.771)[/tex]

[tex]\log_3\left(\dfrac{4}{49}\right)=1.262-3.542[/tex]

[tex]\log_3\left(\dfrac{4}{49}\right)=-2.28[/tex]

Therefore, the value of [tex]\log_3\left(\dfrac{4}{49}\right)[/tex] is [tex]-2.28[/tex].

Answer:

[tex]y - 20 = 24(x - 3)[/tex]

Step-by-step explanation:

Equation of a line:

The equation of a line, in point-slope form, has the following format:

[tex]y - y_0 = m(x - x_0)[/tex]

In which the point is [tex](x_0,y_0)[/tex] and the slope is m.

(3, 20)

This means that [tex]x_0 = 3, y_0 = 20[/tex]. So

[tex]y - y_0 = m(x - x_0)[/tex]

[tex]y - 20 = m(x - 3)[/tex]

Slope:

The slope is the derivative of the function at the point:

The function is:

[tex]y = x^3 - 3x + 2[/tex]

The derivative is:

[tex]y^{\prime}(x) = 3x^2 - 3[/tex]

At the point, we have that [tex]x = 3[/tex]. So

[tex]m = y^{\prime}(3) = 3*3^2 - 3 = 27 - 3 = 24[/tex]

So the equation to the tangent line to the curve a the point is:

[tex]y - 20 = 24(x - 3)[/tex]

Answer: Well, my best guess would be: 1636 beans

apparently the average weight of a jellybean is 1.1 grams

1.8 kg is 1800 grams

1800 / 1.1 = around 1636

So it's around 1636 jelly beans ?

Answer:

Angle 5 is 75 degrees

Step-by-step explanation:

angle 1 is congruent to angle 5

so angle 5 is also 75 degrees.

The measure of angle 2 and 5 are 65° and 85° respectively.

Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal.

Given that, lines A and B are parallel.

Here, m∠1 = 75° and m∠3 = 40°

Now, x+m∠2+m∠3=180°

x=m∠1 (Vertically opposite angles)

x=75°

75°+m∠2+40°=180°

m∠2+115°=180°

m∠2=65°

m∠2=m∠4=65° (Interior alternate angles are equal)

Now, m∠4+m∠3+m∠5=180°

65°+40°+m∠5=180°

m∠5=85°

Therefore, the measure of angle 2 and 5 are 65° and 85° respectively.
