The function y= 5^x passes through the point
wlad13 [49]
The correct answer is c :)
the point is described by two variables: x and y. it is written like that: (x, y). so the first variable in brackets is the x variable. the other is y. so pick every point a-d, put these values into the equation, solve it and check if the values before and after = are the same. if so - you are correct!
look:
c) (1, 5) so x=1, y=5
equation: y=5^x
putting values: 5=5^1 and this is true!

Can someone pls help me I’m so confused!!! :(
Naddika [18.5K]

Answer:

u = 150

Step-by-step explanation:

Number of vertices:

10

Find the sum of the interior angles:

180(n - 2)

180(10 - 2)

180(8)

1440

To find u:

u = 1440 - (130 + 145 + 160 + 150 + 130 + 150 + 125 + 155 + 145)

u = 1440 - (1290)

u = 150

How can you put 32.3 as a mixed number in the simplest form
ludmilkaskok [199]

32.3 is a decimal number in which 3 is the digit at the tenth place.

Mixed number contains a whole number and a fraction part.

32.3 expressed as mixed fraction is 32\frac{3}{10} , here 32 is the whole number  and \frac{3}{10} is the fraction part.

\frac{3}{10} is the fraction in the simplest form.

For this reason, 32.3 expressed as a mixed number in the simplest form is 32\frac{3}{10}.
