Answer:

x = 4

Step-by-step explanation:

All of the sides are the same so every angle is 17x-8.

Every triangle adds up to 180 degrees.

3(17x-8)=180

51x-24=180

+24 +24

51x=204

x= 4

Identify the initial amount a and the growth factor b in the exponential function.

alina1380 [7]

Given the equation A (x) = 30 x 8.3 ^x, we can get the initial amount of A when x is equal to zero. Therefore:

A (0) = 30 * 8.3^0

A (0) = 30

In this case the equation grows by 8.3 times as x increases. Therefore the growth factor is 8.3.

Answers:

initial amount = 30

growth factor = 8.3

The answers are not in the given choices. I believe you are giving the wrong equation. If the correct equation here is:

A (x) = 680 x 4.3 ^x

Then the answers are:

initial amount = 680

growth factor = 4.3

The answers are now in the choices given.

How do you solve the questions <br> Plzzzzz I really need help

Answer:

The answers are given in step-by-step explanation

Step-by-step explanation:

In question 4,

Elina walked 12 miles then she walked 0.25 that distance.

We have to find the distance she walked

Distance=12+0.25 of that distance

= 12+0.25(12)

= 12(1+0.25)= $12\times 1.25$ =15 miles

Hence, A, B, and C are correct

In question 5,

Given circumference is 600 m

we have to find the good approximation area of circle

circumference = 600 m

$2\pi \times r=600$

$\pi \times r$ =300 ⇒ r=95.49

Area of circle is $\pi \times r^2$

= $(3.14)(95.49)^2=28631.587914m^2$

Hence, the good approximation area of circle is $30,000 m^2$

In question 6,

Given d=3t where d represents the distance between the snail and rock in inches and t represents the time in minutes.

Number 3 represents that distance between snail and certain rock is 3 times that of time.

given distance is 9 inches we have to find the time i.e d=3t ⇒ 9=3t ⇒ t=3 minutes.

Hence, will be 3 minutes when snail is 9 inches far from certain rock.

Now, times given 9 minutes we have to find the distance, d=3t=3(9)=27 inches.

Answer:

$\cos{A}=\pm\sqrt{\dfrac{1+\cos{x}}{2}}$

Step-by-step explanation:

$\cos{A}=\cos{\frac{x}{2}}=\pm\sqrt{\dfrac{1+\cos{x}}{2}}$

Apparently, you're supposed to recognize that the formula tells you the value of cos(x/2).
