The will intersect at a point with a positive x coordinate.

We can tell this because they actually already have a shared space on the graph. If you plot the 3 points of g(x) given, you'll see that f(x) and g(x) both share the coordinate (1, 3). As a result, we know that they do intersect and it is where x (1) is a positive number.

I need help find the volume of the composite solid use 3.14 for pi

Evgen [1.6K]

Answer:

$222.312\:\mathrm{in^3}$

Step-by-step explanation:

The composite solid consists of a cylinder and a cone. Therefore, its total volume will be the sum of the volumes of the cylinder and cone:

Volume of the cone: $\frac{1}{3}\cdot 2^2\cdot 3.14\cdot 8.1 =33.912$

Volume of the cylinder: $2^2\cdot 3.14 \cdot 15=188.4$

Thus, the total volume of the solid is:

$33.912+188.4=\boxed{222.312\:\mathrm{in^3}}$

A valet makes $53 each day he works and approximately $7 in tips for each car he parks. if he wants to make at least $186 in one

eimsori [14]

Answer:

19 Cars

Step-by-step explanation:

Write a linear equation:

y=7x+53

Y = Total money

X = cars parked

If we want to earn 186 dollars a day then sub y for 186 and solve x:

186=7x+53

186-53=7x

133=7x

7x=133

x=133/7

x=19

This means that he will need to park 19 cars a day to earn a total of 186 dollars in one day.

In a right triangle, the side adjacent angle a is 12, the

Svetlanka [38]

Answer:

$tan(a)=\frac{opposite}{adjacent}$

Step-by-step explanation:

In a right triangle, the side adjacent angle a is 12, the

hypotenuse is 24.

Angle 'a' is 12

hypotenuse is 24

$sin(a)=\frac{opposite}{hypotenuse}$

$sin(12)=\frac{opposite}{24}$

opposite side = 24 times sin(12)=5

$cos(a)=\frac{adjacent}{hypotenuse}$

$cos(12)=\frac{adjacent}{24}$

adjacent side = 24 times cos(12)=23.5

$tan(a)=\frac{opposite}{adjacent}$

$tan(a)=\frac{5}{23.5}$
