Answer:

the first one

Step-by-step explanation:

Note that the right triangle 90°- 60° - 30° has

legs 1 and $\sqrt{3}$ with hypotenuse 2

The first triangle has sides which are multiples of this special triangle

legs (1 × 5) and ( $\sqrt{3}$ × 5) = 5 and 5 $\sqrt{3}$

with hypotenuse = (2 × 5) = 10

Hence the first triangle is the special triangle

Answer:

During a 336-mile trip the car consumes 9.6 gallons of gasoline.

During a m-mile trip the car consumes 24 gallons of gasoline.

When the number of miles increases, the number of gallons of gasoline also increases. The car consumes gasoline at the same rate, so the ratio of miles to gallons is constant. The proportion is:

336/9.6= m/24

Gertrude started an experiment with 15 gummy bears. After 6 days, there were 1,523 gummy bears. Write an exponential function th

Lunna [17]

9514 1404 393

Answer:

y = 15·2.1599^x

Step-by-step explanation:

We know that the number changed by the ratio 1523/15 = 101.5333... in 6 days, so the daily multiplier is the 6th root of this:

b = 101.5333...^(1/6) = 2.1599 . . . rounded to 4 dp

Of course, the coefficient 'a' in the equation is the initial number, 15.

Your exponential equation is ...

y = 15·2.1599^x

a = 15

b = 2.1599

Consider the equation

muminat

Answer:

A. $a=10\\ \\b\neq -8$

B. $a=10\\ \\b= -8$

Step-by-step explanation:

Consider the equation

$2(5x-4) = ax + b$

A. This equation has no solutions when the coefficients at x are the same and the free coefficients are not the same.

First, use distributive property:

$2(5x-4)=2\cdot 5x-2\cdot 4=10x-8$

So, the equation is

$10x-8=ax+b$

This equation has no solutions when

$a=10\\ \\b\neq -8$

B. The equation has infinitely many solutions when the coefficients at x are the same and the free coefficients are the same too.

So, the equation

$10x-8=ax+b$

has infinitely many solutions when

$a=10\\ \\b= -8$

In other cases, the equation has a unique solution

The function m=30-3r represents the amount m (in dollars) of money you have after renting r video games.

san4es73 [151]

The domain of the equation are all the possible values of the independent variables that would make the equation reasonable, possible or true. In this item, the independent variable is r. This could take a value of 0 up to the point when m is equal to zero.
m = 30 - 3r = 0
r = 10

The domain is therefore [0, 10].

The range is the value of the dependent variable which would be from 0 to the point when no video game is played. This is, [0, 30].

The function is discrete because r and m cannot take every value in the number line.
