Assume that f is a one-to-one function.

Mathematics

Pavlova-9 [17]2 years ago
3 0

It is given in the question that f is a one-to-one function.

And for a one-to - one function,

If

f(a)=b, \ then \ f^{-1} (b) =a

So we will get

a. If \ f(3)=15, \ then \ f^{-1} (15) =3
\\
b. If \  f^{-1}(6)=4, \ then \ f(4)=6

If triangle ABC is isosceles and triangle DBE is equilateral what is the measure of angle C
luda_lava [24]

Answer:

43°

Step-by-step explanation:

For triangle ABC:

A = C so all we need to do is to calculate the value of B

The measure of angle ABD is given as 17° so the measure of angle EBC must be 17° as well

Since DBE is an equilateral triangle angle is DBE = 60°

17 + 17 + 60 = 94 this is the measure of angle B

The sum of interior angles in a triangle is equal to 180

A + B + C = 180

A + C + 94 = 180

A + C = 86 since A = C we divide 86 by 2

C = 43°

Help plz no wrong answers plz help me ASAP thanks!
wariber [46]

Answer:

480

Step-by-step explanation:

The probability she will roll 2 odd numbers is 12/50  (the number of odd rolls over the total).  This simplifies to 6/25

Multiply the probability times the total number of rolls to get a good estimate of the number of rolls that till be odd odd

6/25 * 2000 =480
