Hello!

As you can see, the angle is a straight angle, which measures 180°. One angle measures 80°.

180 - 80 = 100

That means the rest added all together measure 100°.

3x + 2x = 5x

5x = 100

Divide both sides by 5

$\frac{5x}{5} = \frac{100}{5}$

$\framebox{x = 20 \°}$

$3x+2x+80=180\\
5x=100\\
x=20$

The population of rabbits on an island is growing exponentially. In the year 1991, the population of rabbits was 9100, and by 19

lisabon 2012 [21]

Answer:

$39,223\ rabbits$

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by

$y=a(1+r)^x$

where

y is the population of rabbits

x is the number of years since 1991

a is the initial value

r is the rate of change

we have

$a=9,100$

substitute

$y=9,100(1+r)^x$

For the year 1998

the number of years is equal to

x=1998-1991=7 years

so

we have the ordered pair (7,18,000)

substitute in the exponential equation and solve for r

$18,000=9,100(1+r)^7$

$(18,000/9,100)=(1+r)^7$

elevated both sides to 1/7

$(1+r)=1.1023$

$r=0.1023$

therefore

$y=9,100(1+0.1023)^x$

$y=9,100(1.1023)^x$

Predict the population of rabbits in the year 2006

Find the value of x

x=2006-1991=15 years

substitute the value of x in the equation

$y=9,100(1.1023)^{15}$

$y=39,223\ rabbits$

Pls help me calculate the inverse of y equals 2x over x-7

NeTakaya

Y = 2x/x-7

x = 2y/y-7

xy - 7x = 2y

-7x = 2y - xy

-7x = y(2-x)

y = -7x / 2-x

y = 7x / x-2

f-¹(x) = 7x / x-2

Evaluate 5! + 2!. 60 122 5,040

ludmilkaskok [199]

! Means starting from that number multiply by every number down to 1.

5!= 5•4•3•2•1 = 20•6=120

2!= 2•1=2

120+2=122 :)

Tangent is positive in quadrants I and IV only.<br>True or False

zhannawk [14.2K]

Answer:

The statement is false

Step-by-step explanation:

we know that

$tan(x)=\frac{sin(x)}{cos(x)}$

The tangent function will be positive when the sine function and the cosine function have the same sign

so

In the first quadrant the tangent function is positive

In the third quadrant the tangent function is positive

so

The statement is false
