Answer and Step-by-step explanation:

Simply multiply 3 by 5.

We do this because for every hour we run, we run 5 miles, and the person runs for 3 hours.

So, the answer is 15 miles.

It would be 15 miles because it’s 5 miles per hour and you run for 3 hrs so you multiply 5 times 3

N=4; 2i and 3i are zeros f(-1)=50

Nonamiya [84]

Solution:- $\text{Let f(x) be any nth degree polynomial with n=4}\\$

$\text{Given that 2i and 3i are the zeroes of f(x)}$

$\text{so (x-2i) and (x-3i) are factors of f(x)}$

$\text{Since 2i is a zero of f(x) then its conjugate -2i is also a zero of f(x)}$

$\Rightarrow(x+2i) \text{is a factor}\\\text{Similarly, conjugate of 3i is -3i is also a zero of f(x) }\\\Rightarrow(x+3i)\text{is a factor}\\\text{So , }\\f(x)=k(x-2i)(x+2i)(x-3i)(x+3i)\\=k(x^2-(2i)^2)(x^2-(3i)^2)\\=k(x^2-4i^2)(x^2-9i^2)\\=k(x^2+4)(x^2+9)\\=k(x^4+13x^2+36)\\\text{As given}\\f(-1)=50\\\Rightarrow k((-1)^4+13(-1)^2+36)=50\\\Rightarrow k(1+13+36)=50\\\Rightarrow k(50)=50\\\Rightarrow k=1\\\text{So by substituting k=1 in f(x) we get ,}\\f(x)=(x^4+13x^2+36)$

describe a sequence of transformations that maps triangle abc onto a''b''c'', a student starts with a reflection over the x-axis

arsen [322]

Note that both triangles are congruent, so no dilations/contractions occured.

Going clockwise, we have ABC but A''C''B'', so a reflection occurred, not a rotation.

Thus, one sequence of transformations is:

1. Reflect ABC across the x-axis and call this new triangle A'B'C'.
2. Translate A'B'C' 2 units right and 6 units up so that its image is A''B''C''.

I hope my answer has come to your help. God bless and have a nice day ahead!
