Answer:

x=0,-1 and x=

x=\frac{2+\sqrt{10}}{3},\frac{2-\sqrt{10}}{3}x=

Step-by-step explanation:

1 Cancel 2 on both sides.

3{x}^{2}+3x=03x

+3x=0

2 Factor out the common term 3x3x.

3x(x+1)=03x(x+1)=0

3 Solve for xx.

x=0,-1x=0,−1

1 Move all terms to one side.

3{x}^{2}-3x-1-x-1=03x

−3x−1−x−1=0

2 Simplify 3{x}^{2}-3x-1-x-13x

−3x−1−x−1 to 3{x}^{2}-4x-23x

−4x−2.

3{x}^{2}-4x-2=03x

−4x−2=0

3 Use the Quadratic Formula.

x=\frac{4+2\sqrt{10}}{6},\frac{4-2\sqrt{10}}{6}x=

4+2√

4−2√

4 Simplify solutions.

x=\frac{2+\sqrt{10}}{3},\frac{2-\sqrt{10}}{3}x=

2+√

2−√

The number of airline passengers in 1990 was 466 million. The number of passengers traveling by airplane each year has increased

taurus [48]

Answer:

2010.

Step-by-step explanation:

We have been given an exponential growth formula $P(t)=466\cdot 1.035^t$ , which represents number of passengers traveling by airplane since 1990.

To find the year in which 900 million passengers will travel by airline, we will equate the given formula by 900 and solve for t as:

$900=466\cdot 1.035^t$

$\frac{900}{466}=\frac{466\cdot 1.035^t}{466}$ $1.9313304721030043=1.035^t$

Take natural log of both sides:

$\text{ln}(1.9313304721030043)=\text{ln}(1.035^t)$

Using property $\text{ln}(a^b)=b\cdot \text{ln}(a)$ , we will get:

$\text{ln}(1.9313304721030043)=t\cdot \text{ln}(1.035)$

$0.658209129198=t\cdot 0.034401426717$

$\frac{0.658209129198}{0.034401426717}=\frac{t\cdot 0.034401426717}{0.034401426717}$

$19.1331927775=t\\\\t=19.1331927775$

This means that in the 20th year since 1990, 900 million passengers would travel by airline.

$1990+20=2010$

Therefore, 900 million passengers would travel by airline in 2010.

A small explanation would be really appreciated

shutvik [7]

Step-by-step explanation:

the 2 angles marked with orange and green are equal becos the question said that the indicated angles are congruent meaning same deg. so 180 - that given angle = the 2 marked angles (based on the rule known as angles on a str line are supplementary)

since the 2 marked angles are same, you can say that d and k are parallel due to the rule of alternate angles

If you like to venture further, feel free to check out my insta (learntionary). It would be best if you could give it a follow. I'll be constantly posting math tips and notes! Thanks!

Does anyone know this?

Tresset [83]

<ABC would equal 106

seeing in triangle ABD angle A equals 67 you would multiply that by 2 and then subtract it from 180 to get 46, and then triangle DBC all the angles would equal 60. so then add 46 to 60 to get 106 the measure of <ABC

Kristin and her family left their campsite to take a bike ride. They biked 5 miles west and then 12 miles north. How far are the

pickupchik [31]

Answer:

they are 17 miles away from their campsite.

Step-by-step explanation:

we get the answer by adding the miles traveled north to the miles traveled west, and we get the total number of miles they traveled away from their campsite.

5 + 12 = 17
