Answer:

Yes, PQR ~ TSV with a scale of 1 : \sqrt{3}

Step-by-step explanation:

Yes the triangles are congruent for the statement given in option C

The scale 1 : \sqrt{3} shows that the side lengths are proportional

PQ/TS = QR/SV

3\sqrt{3}/6/\sqrt{3} and that's simplified as 1/\sqrt{3}

Bertha has $2400 more invested at 4% than she has at 5%. If her annual income from these two investments is $294, how much does
Oksana_A [137]
So
x (4%)
y (5%)
x=y+2400
0.04x+0.05y=294

Once you solve them, x=4600 and y=2200
so 4%= $4600
5%= $2200

What are the domain and range of the logarithmic function f(x) = log7x? Use the inverse function to justify your answers.
S_A_V [24]

Answer:


Step-by-step explanation:

Since log is defined by all positive real  numbers

therefore domain is all  positive real number that is ( 0,∞)

Range is given by real numbers

inverse of the given function is  (10^x)/7

Whose domain is all real numbers and range is all positive real number

And since we know that domain of function and range of its inverse

& range of a function and domain of its inverse is same

which we are getting in the problem

so  answer is justified
